1. AUSTRALIA ‒ RENEWABLES GROWTH, WIND, SOLAR

Australia could be at 86% wind and solar by 2050 – on economics only

Giles Parkinson, 10 July 2018

Australia could source 86 per cent of its electricity from wind and solar by 2050, based on economics only and regardless of any climate or emissions policy, according to Bloomberg New Energy Finance.

The global research and news group says that level of wind and solar could be reached quicker, and will need to in order to match the Paris climate target of 2°C, let alone 1.5°C, but the transition to wind and solar is inevitable.

Powering Progress: States Renewable Energy Race

Climate Council of Australia, 16 October 2018

The renewable energy boom is accelerating in Australia, and across the world. In the absence of meaningful commonwealth government leadership, state and territory governments are leading Australia’s electricity transition from fossil fuels to renewable energy and storage.

This report rates states and territories based on their performance across a range of metrics. These include each state’s percentage of renewable electricity, the proportion of households with solar and policies that support renewable energy.

Australia at 19% renewables – NEG 2030 target to be reached in 2021

Giles Parkinson, 6 July 2018

Australia’s electricity grid reached a 19 per cent share of renewable energy in the year to June 30, and with a host of new wind and solar capacity to be added in the next two years will meet its 2030 target for emissions in the electricity sector nine years early.

The latest analysis from The Australia Institute, in its regular energy market audit, is just the latest in a string of reports that highlight how ineffective the Coalition government’s emissions target are.

Clean Energy Australia renewables jobs and investment data – 2018

Renewable energy sources accounted for 16.94% of electricity generation in Australia in 2017, comprising hydro 5.74%, wind 5.72%, small-scale solar-PV 3.43%, bioenergy 1.65%, other solar 0.41%.

Renewables percentage contribution to total electricity generation: Tasmania 88%, SA 45%, Vic 16%, WA 14%, NSW 11%, Qld 8%.

Renewables smash records in 2017, but 2018/19 will be bigger

Sophie Vorrath, 30 May 2018

The Clean Energy Council has detailed a year of remarkable deal-making and record-smashing project activity in Australia’s large-scale solar and wind sectors in its latest annual snapshot of the national clean energy market.

Clean Energy Australia Report 2018

Looks back at a 2017 when 16 large-scale renewable energy project, totalling around 700MW of new generation capacity, were completed and connected to the National Electricity Market.

Among those, four large-scale solar projects were completed in 2017, taking Australia’s total installed large-scale solar capacity to 450MW at the end of the year, from just 34 MW at the end of 2014.

For the wind sector, the 547MW of new capacity added in 2017 was the third highest amount added in the history of the Australian industry, bringing total generation capacity across the country to 4816MW. …

And while 2017 was a record year, CEC chief Kane Thornton says it is “just a glimpse” of what is shaping up to be an unprecedented level of activity in the next couple of years.

“Perhaps most significantly, the large-scale renewable projects either under construction or which had attracted finance add up to more than seven times the amount of work completed in 2017,” he said in comments at the launch of the 2018 report.

“These 50 projects add up to 5300MW of new capacity and 5750 direct jobs.”

Australia can supply 50 per cent of its power needs from clean energy by 2030

Sheradyn Holderhead, The Advertiser, 15 Feb 2018

AUSTRALIA could reach 50 per cent renewable energy by 2030 without significant new storage, given the projects in the pipeline in the state, a new report shows.

The Climate Council report found that the country was on the verge of an energy storage boom because the cost of lithium-ion batteries was rapidly dropping. Despite wind and solar PV already comprising 57 per cent of power generated in South Australia, the report found that renewables produce just 16 per cent of the national electricity supply.

Climate Council energy expert Professor Andrew Stock said the transition to renewable energy and storage was inevitable and happening now. He criticised the “lack of ambition” in the Federal Government’s National Energy Guarantee and said it placed the renewables and storage boom at risk.

Solar installs through the roof, as Australians deliver record growth

Sophie Vorrath, 18 January 2018

Extraordinary figures continue to roll in from the year that was for renewable energy in Australia, but easily the most outstanding so far are the numbers – and “eye watering charts” – that have just come in on national solar PV installations for 2017.

The latest tally from PV market analysts SunWiz has revealed a record smashing total so far of 1.25GW of solar PV installed across 2017, making it out and away the biggest year for the market in Australia ever, eclipsing the former record set in 2012.

Renewables record: solar and wind power blow gas out of the water
16 October 2017

Solar and wind powered more homes than ever before last month and produced more energy than gas, the latest Renewable Energy Index shows. Solar and wind combined generated a record high of 2,363 GWh of electricity, compared with 2,186 GWh for gas.
The analysis, compiled by Green Energy Markets, reveals renewable energy from all sources made up 21.9% of electricity generated on Australia’s main grids — avoiding the equivalent of 9.3 million cars-worth of carbon pollution.
The Index also shows the renewable energy sector employed 17,521 people throughout September, with Queensland again coming out on top with 6,810 renewable jobs.

Record year for renewable energy as costs fall and hydro returns to form

30 May 2017

A record share of Australia’s electricity came from renewable energy in 2016, largely thanks to improved rainfall in key hydro catchments and a series of new wind and solar projects, according to a new report released today by the Clean Energy Council.
The Clean Energy Australia Report 2016 says more than 17 per cent of Australia’s electricity came from renewable energy during the year – the highest proportion at any time this century, putting Australia well on track to deliver the 2020 Renewable Energy Target (RET).

Surge in renewables set to balance Australia’s future energy equation

Brian Robins, 29 June 2017

Australia’s energy future will be increasingly reliant on renewable energy sources, with the operator of the nation’s energy markets conceding that even with a forecast 30 per cent rise in population over the next two decades the amount of energy travelling across the grid will be little changed.

Central to the forecast from the Australian Energy Markets Operator, which runs the nation’s wholesale gas and electricity markets, is the view that more households will install rooftop solar systems as their prices decline, amid an ongoing trend towards installing more energy efficient appliances.

Australian solar capacity now 6GW, to double again by 2020

Giles Parkinson, 27 April 2017

Australia’s total solar power capacity has reached 6GW and is expected to double over the next few years as Australian households continue to invest in rooftop panels to reduce electricity bills, and the large-scale solar sector takes off after years of promise.

The latest industry analysis on installed capacity – released by the Australian Photovoltaic Institute – shows that rooftop solar capacity has now reached 5.6GW and large-scale solar capacity is now at 496 MW, and growing fast.

‘Towards the next generation: delivering affordable, secure and lower emissions power’

Climate Change Authority and Australian Energy Market Commission

1 June 2017

Report webpage or PDF of full report.

Description: The Minister for the Environment and Energy, the Hon Josh Frydenberg MP, asked the Australian Energy Market Commission (AEMC) and the Climate Change Authority to jointly provide advice on policies to enhance power system security and to reduce electricity prices consistent with achieving Australia’s emissions reduction targets in the Paris Agreement. In developing its advice, the Authority and the AEMC were asked to draw on existing analysis and review processes and be informed by independent modelling. This report outlines the AEMC and the Authority’s findings on these important matters.

Australia’s energy sector is undergoing a significant transformation. This change is being driven by new technologies, business models and consumer preferences. It also reflects the intent of governments (particularly the Commonwealth Government as well as the state and territories) to reduce emissions from energy generation to meet emissions reduction targets or, in some cases, to support renewable technology industries.

2. AUSTRALIAN DEEP EMISSIONS CUTS STUDIES

100% Renewable Electricity in Australia

Andrew Blakers, Bin Lu and Matthew Stocks (Australian National University), February 2017, ‘100% Renewable Electricity in Australia’.

Abstract: We present an energy balance analysis of the Australian national electricity market in a 100% renewable energy scenario in which wind and photovoltaics (PV) provides 90% of the annual electricity. The key outcome of our modelling is that the additional cost of balancing renewable energy supply with demand on an hourly basis throughout the year is modest: A$25-30/MWh (US$19-23/MWh).

100 percent renewable energy by 2030

November 2017

Australia can have an electricity grid entirely run by renewable energy by 2030, according to a new research paper by Renew, formerly the Alternative Technology Association (ATA).

The paper, 100% Renewable Grid by 2030, says the target can be achieved by accelerating the installation of wind and solar power by 80% backed up by pumped hydro energy storage facilities and extra transmission lines.

Lead author Andrew Reddaway, energy analyst at Renew, said reaching full renewable energy by 2030 was cheaper and less risky than building new coal-fired power stations.

Renew’s forecasts towards a fully renewable grid in the national electricity market are based on recent research by the Australian National University. The paper considered recent trends and developments in projects such as Snow Hydro 2.0

Australia could be 100% renewable by 2030s, meet Paris targets by 2025

Sophie Vorrath, 10 September 2018

Australia could reach the equivalent of 100 per cent renewables for its electricity needs by the early 2030s by doing nothing more than maintaining the current pace of wind and solar development, a new research report has found.

The report – published by a heavy-hitting team of Australian National University researchers, including solar PV and pumped hydro expert Andrew Blakers – says keeping up the current rate of renewable energy deployment would also meet Australia’s entire emissions reduction task “for the whole economy” by 2025.

To reach these conclusions, the team analysed data for the federal government’s own Clean Energy Regulator, showing that during 2018 and 2019 the nation would install about 10,400MW of new renewable energy.

ANU Energy Change Institute director Professor Ken Baldwin said that at that rate, Australia would eclipse the Renewable Energy Target, reaching 29 per cent in 2020, and by 2025 would reach 50 per cent – a number the federal Coalition likes to say is “recklessly high”, even for 2030.

Perhaps even more importantly, staying on the current trajectory would see electricity sector emissions reduced by 26 per cent in 2021, and the Paris economy-wide emissions reductions target of 26 per cent met five years early, in 2025. …

The ANU forecast compares to recent modelling from the Australian Energy Market Operator, which shows renewables making up 46 per cent of NEM generation by 2030 in their “neutral scenario”, and 61 per cent of generation by 2030 in their “fast change” scenario.

New report shows 100% renewable by 2030 can save Australia money

Giles Parkinson, 19 April 2016, RenewEconomy

A new report from the Institute for Sustainable Futures in Sydney says a rapid transition to a 100 per cent renewable energy system can save Australia money – with avoided fuel costs to quickly offset the extra capital expenditure of building wind, solar and other renewable energy installations.

“The transition to a 100 per cent renewable energy system by 2050 is both technically possible and economically viable in the long term,” the report says. And by 100 per cent renewable, it means all energy use, including transport and heating.

The report canvasses two renewable energy scenarios, one based on a high level of renewable energy in the electricity grid, but with transport largely reliant on fossil fuels. The second is the Advanced Renewables scenario, which canvasses a totally renewable electricity system by 2030 and a fully renewable energy system by 2050.

Australians can have zero-emission electricity, without blowing the bill

6 Dec 2016

Paul Graham ‒ Chief economist, CSIRO energy

In a report released by CSIRO and Energy Networks Australia ‒ titled Electricity Network Transformation Roadmap Key Concepts Report ‒ we show that Australia is so far making rocky progress on reducing emissions, maintaining energy security and keeping prices low. But we also show how Australia can regain world leadership, delivering cheap electricity with zero emissions by 2050.

University of New South Wales Simulation Study (2012)

Ben Elliston, Mark Diesendorf and Iain MacGill, 2012, ‘Simulations of scenarios with 100% renewable electricity in the Australian National Electricity Market’, Energy Policy, vol. 45, pp.606-613

Abstract

As a part of a program to explore technological options for the transition to a renewable energy future, we present simulations for 100% renewable energy systems to meet actual hourly electricity demand in the five states and one territory spanned by the Australian National Electricity Market (NEM) in 2010. The system is based on commercially available technologies: concentrating solar thermal (CST) power with thermal storage, wind, photovoltaic (PV), existing hydro and biofuelled gas turbines. Hourly solar and wind generation data are derived from satellite observations, weather stations, and actual wind farm outputs. Together CST and PV contribute about half of total annual electrical energy supply.

A range of 100% renewable energy systems for the NEM are found to be technically feasible and meet the NEM reliability standard. The principal challenge is meeting peak demand on winter evenings following overcast days when CST storage is partially charged and sometimes wind speeds are low. The model handles these circumstances by combinations of an increased number of gas turbines and reductions in winter peak demand. There is no need for conventional base-load power plants. The important parameter is the reliability of the whole supply-demand system, not the reliability of particular types of power plants.

Highlights

We simulate 100% renewable electricity in the Australian National Electricity Market.

The energy system comprises commercially available technologies.

A range of 100% renewable electricity systems meet the reliability standard.

Principal challenge is meeting peak demand on winter evenings.

The concept of ‘base-load’ power plants is found to be redundant.

Renewables to be cheaper than coal even without climate policy, CSIRO says

2 January 2019

The CSIRO and the energy market operator say existing coal plants are still one of the lowest cost forms of power but new wind and solar farms will soon be cheaper, even without a carbon price.

Australia solar costs hit “extraordinary” new lows – $50s/MWh

Sophie Vorrath & Giles Parkinson, 27 June 2018

The cost of building new large-scale solar energy generation in Australia has fallen to an “extraordinary” new low, the head of the Australian Renewable Energy Agency has said, citing industry reports of numbers down around the $50/MWh mark.

Australia’s PV price plunge has seen the cost of utility-scale solar fall from around $135/MWh when ARENA launched its first auction in 2015, to “somewhere in the $50s” today, or $1/W, ARENA chief Ian Kay said on Wednesday.

Wind and solar slashing corporate energy costs by 40%
Giles Parkinson, 1 June 2018

The continuing fall in the cost of new wind and solar farms, and the emergence of new firming contract products, is allowing large corporate and industrial users to slash energy costs by up to 40 per cent.

TFS Green, a Melbourne-based wholesale energy and environmental market broker, is on Friday launching its new “Renewable Energy Hub”, a day after the formal announcement of its first transaction with the Kiamal solar farm and Mars Australia.

TFS Greens’s Chris Halliwell says wind and solar is clearly delivering electricity at a 40 per cent discount from what is available to medium and large users elsewhere on the grid.

That assessment is shared by Sanjeev Gupta and his team at SIMEC ZEN Energy, which is looking at similar savings from building a massive suite of large-scale solar, pumped hydro and battery storage to power the Whyalla steelworks and other big energy users.

A cost curve for emissions reductions & energy storage

Reputex, March 2017, ‘An Energy Trilemma: A cost curve for emissions reductions & energy storage in the Australian electricity sector’

See media release and report summary.

From the media release:

  • The rising price of gas, coupled with the falling cost of energy storage, has now made renewable energy storage cheaper than gas-fired power in providing reliable generation, such as instantaneous peaking or load-following supply.
  • Flexible renewable supply – such as a solar plant with battery storage that can ramp up even if the sun is not shining – is expected to create a decreasing need for “baseload-only” facilities, enabling states to rely on storage to overcome intermittency concerns and provide clean, reliable supply – at least cost.
  • Notably, findings also indicate “clean coal” will not be commercially mature before 2030, meaning it will not contribute to Australia’s 2030 target under the Paris Agreement.

From the report summary:

Key findings include:

  • Demand reduction via the take-up of solar PV has the lowest marginal cost of emissions reductions in the electricity sector, in line with an anticipated drop in capital costs, and continued availability of financing.
  • “Clean coal” such as Carbon Capture and Storage (CCS) and High Efficiency, Low Emissions” (HELE) coal is not forecast to be commercially mature until at least 2025. Subsequently, clean coal is projected to have a limited impact in support of Australia’s 2030 target under the Paris Agreement.
  • New low cost: Wind is displacing existing generation, causing existing facilities to generate less energy, recover revenue less frequency, and exit the market. As this occurs, system reliability has become an issue, most noticeably where intermittent generation has a high penetration rate, given it does not necessarily coincide with peak demand (timing) and cannot be easily ramped up to follow a load forecast (controllability).
  • Intermittent technologies do not provide the same contribution to system reliability as dispatched technologies, and may therefore require additional system investment (for example in storage) to ensure guaranteed supply.
  • Analysing the “full cost” of renewables, with energy storage, raises the cost recovery for low-cost intermittent generators significantly above their LCOE, however, findings indicate that on a like-for-like basis clean energy is now cheaper than gas-fired generation, driven by higher gas prices and falling storage technology costs.
  • Renewables with energy storage have therefore surpassed gas as the cheapest source of new flexible power in Australia, with analysis indicating these sources may alleviate system pressure by providing load-following and peaking generation services.
  • Analysis indicates that this will create a decreasing need for baseload-only facilities, while enabling South Australia, Victoria, Queensland and New South Wales to rely on new storage technologies to provide affordable, clean, and secure energy – while improving system reliability.

Wind energy’s biggest month, and how it keeps prices down

Giles Parkinson, 8 June 2016

Wind energy in Australia has enjoyed its biggest every month in May, producing nearly a quarter more electricity than its previous record month, and overtaking hydro to provide 8.5 per cent of electricity demand in the country’s main grid.

The record output came, coincidentally, in the same month that the last coal fired power station in South Australia was closed (May 9). And a new analysis from energy consultants Pitt & Sherry points to how wind generation is keeping a lid on wholesale electricity prices.

The Pitt & Sherry analysis notes that four states recorded record monthly totals in May – South Australia (where wind met 49 per cent of demand), Victoria, New South Wales and Tasmania. (There is only one very small wind farm in Queensland and Western Australia operates on a separate grid).

How rooftop solar is saving billions on energy bills for all consumers

Giles Parkinson, 16 October 2017

A major new study has underlined the crucial role played by rooftop solar in moderating energy prices: without it, the study says, the aggregate cost of electricity would have been several billion dollars higher over the past year.

The study by Energy Synapse, commissioned by the community lobby group Solar Citizens, reinforces previous estimates of the broad benefits of the more than 6GW of rooftop solar installed on more than 1.7 million household and business rooftops.

That capacity is often demonised by vested interests as “free-loading” on the network and other consumers, but the study proves otherwise.

Cheap wind, solar will make Australia a magnet ‒ Bloomberg

Ben Potter, 15 June 2017

Cheap wind and solar power will make Australia a magnet for energy-intensive industries such as smelting again within a decade or two, reversing the current trend for large smelters to back off production or threaten closure because of soaring electricity prices, Bloomberg New Energy Finance says in its 2017 Outlook.

Prices for solar PV rooftop panels, wind power and batteries will fall rapidly and quickly undercut coal and gas power, driving rapid uptake of these “distributed energy” technologies and making Australia one of the most decentralised energy markets in the world with a massive 45 per cent of power capacity “behind the meter” by 2040.

Small-scale PV will be the largest single source of generation capacity by 2040, with 44 gigawatts ‒ 31 per cent of the mix. Solar PV will “take the place of coal as the backbone of the national energy supply”, BNEF’s New Energy Outlook 2017 says.

Batteries in homes and business premises will supply another 15GW, helping to stabilise the grid at times of peak demand through “demand response” as coal supplies a diminishing share of demand. It projects that levelised (all in) costs of wind power will fall from $US57/MWh ($76/MWh) today to $US33/MWh in 2040, and solar PV will plummet from $US71/MWh today to $US26/MWh in 2040.

The solar PV boom will be joined by a boom in batteries, Bloomberg New Energy Finance’s New Energy Outlook 2017 projects Bloomberg New Energy Finance, New Energy Outlook 2017

Wind and solar already significantly undercut the cost of power from new coal plant ‒ which BNEF estimates at $US94-172/MWh ‒ and by 2023 will undercut the cost of power from refurbished coal plant.

Solar’s new sweet spot: Low cost, compact PV plants at $1/watt

Giles Parkinson, 22 June 2017

There’s been a lot of attention paid to the big boom in large scale solar in Australia over the past nine months, with more than 2.4GW under construction across the country, and another 8GW in the pipeline, by RenewEconomy’s estimates.

The focus has been on the big end of this construction boom, but something interesting is happening at the smaller end of the market – the emergence of quick-to-build, compact MW scale solar plants that are redefining the technology’s economics.

The majority of large scale solar plants are slowed down by connection issues and getting a power purchase agreement and finance. But there has been no such inhibition for YD Projects, which this week completed the first of a number of solar projects on the NSW/Queensland border.

5. RENEWABLE ENERGY JOBS IN AUSTRALIA

Wind farms power big surge in renewable energy jobs

Cole Latimer, 25 January 2018

A boom in wind farms is fuelling a jobs surge in the renewable energy industry with 17 per cent employment growth in the sector in December.

Nationwide, there are now 15,691 renewable energy jobs, rising to 21,168 when including those in small-scale rooftop solar installation. This is a 17 per cent month on month increase from November job figures. …

Renewables delivering – despite enemies and “lukewarm defenders”

Tristan Edis, 28 August 2017

Today Green Energy Markets has released the Renewable Energy Index, which is a monthly publication tracking: the amount of power produced from renewable energy; the jobs it’s creating; the power bill savings it is delivering for Australian households and businesses; and the environmental benefits of the rising use of clean power.

The story is an impressive one. At the end of June, large-scale renewable energy projects under construction were estimated to create enough jobs to employ 8,868 people full-time for a year. Then in our July edition it had grown by more than a thousand to 9,897 job-years (a person employed full time for a year) thanks to the commitment of a further seven projects.

On top of this we estimate almost 4,000 people were employed full-time in installation, design and sales of rooftop solar systems over the 2016-17 financial year. Renewable energy has now grown to 17 per cent of our power supply across the main east and west coast grids, up from about 7 per cent 10 years ago.

Renewables record: solar and wind power blow gas out of the water
16 October 2017

Solar and wind powered more homes than ever before last month and produced more energy than gas, the latest Renewable Energy Index shows. Solar and wind combined generated a record high of 2,363 GWh of electricity, compared with 2,186 GWh for gas.
The analysis, compiled by Green Energy Markets, reveals renewable energy from all sources made up 21.9% of electricity generated on Australia’s main grids — avoiding the equivalent of 9.3 million cars-worth of carbon pollution.
The Index also shows the renewable energy sector employed 17,521 people throughout September, with Queensland again coming out on top with 6,810 renewable jobs.

South Australia on track to meet 75% renewables target

25 July 2018

South Australia’s energy minister says the state is on track to have 75% of its electricity from renewable sources by 2025 – the target set by the former Labor premier Jay Weatherill and once rejected by his Liberal government. … The Australian Energy Market Operator has projected South Australia would have 73% renewable power by 2020/21 while consultants Green Energy Markets found it could reach 74% by 2025 without any additional policies being introduced.

A new Climate Change Strategy for South Australia was released by Premier Jay Weatherill and Minister for Climate Change Ian Hunter on 29 November 2015. South Australia’s Climate Change Strategy 2015-2050 – Towards a low carbon economy sets a framework for significantly reducing emissions in SA while maximising economic opportunities.

SA Low Carbon Economy Experts Panel

South Australia’s Low Carbon Economy Experts Panel, Nov. 2015, Findings and Recommendations.

As a result of its assessment, the Panel found that it is feasible for South Australia to achieve a target of net zero emissions by 2050 and that a commitment to this target will position South Australia well in a low carbon world.

The modelling for the Panel did not include consideration of whether the nuclear and carbon capture and storage scenarios modelled at the national level are a cost-effective means to move to low carbon electricity for South Australia. The Deep Decarbonisation Pathways modelling found that nuclear power stations generally need to be of a certain size to be cost effective and thus precluded their consideration for use in smaller States such as South Australia. In addition, South Australia’s capacity for cost-effective carbon capture and storage is unknown.

Climate Institute ‒ Clean Energy Jobs: South Australia Snapshot (c.2011)

Some highlights of the South Australia study include:

‒ A large untapped resource: The modelling results show strong growth in South Australia’s electricity sector, with an additional 5,400 MW of generating capacity projected to be installed by 2030. This includes renewable energy, including wind, solar and geothermal, as well as gas.

‒ State-wide employment: Based on the modelling results it is estimated that close to 5,000 new jobs will be created in South Australia’s electricity sector by 2030, including 1,089 permanent ongoing jobs, 2,688 construction jobs and 1,189 manufacturing jobs. The vast majority of these jobs will be in renewable energy.

‒ Regional clean energy jobs: Thousands of jobs are up for grabs in regional South Australia, including over 1,200 on the Eyre Peninsula and over 1,300 in the York and Lower North region.

AEMO sees South Australia at 73% renewables by 2020/21

Giles Parkinson, 2 March 2018

The Australian Energy Market Operator has predicted, in a document published in December, that – based largely on the federal renewable energy target – it expects South Australia to reach 73% renewable energy by 2020/21. It goes further. It says that SA will likely reach between 75% and 80% renewable energy share by 2026/27, depending on the policy pathway.

The Feasibility Of 100% Renewable Electricity Systems: A Response To Critics

Diesendorf M, Elliston B, October 2018, The Feasibility Of 100% Renewable Electricity Systems: A Response To Critics, Renewable & Sustainable Energy Reviews, 93:318-330

Highlights:

  • Large-scale electricity systems based on 100% renewable energy can meet the key requirements of reliability, security and affordability.
  • This is even true where the vast majority of generation comes from variable renewables such as wind and solar PV.
  • Thus the principal myths of critics of 100% renewable electricity are refuted.
  • Arguments that the transition to 100% renewable electricity will necessarily take as long or longer than historical energy transitions are also refuted.
  • The principal barriers to 100% renewable electricity are neither technological nor economic, but instead are primarily political, institutional and cultural.

Abstract:

The rapid growth of renewable energy (RE) is disrupting and transforming the global energy system, especially the electricity industry. As a result, supporters of the politically powerful incumbent industries and others are critiquing the feasibility of large-scale electricity generating systems based predominantly on RE. Part of this opposition is manifest in the publication of incorrect myths about renewable electricity (RElec) in scholarly journals, popular articles, media, websites, blogs and statements by politicians. The aim of the present article is to use current scientific and engineering theory and practice to refute the principal myths. It does this by showing that large-scale electricity systems that are 100% renewable (100RElec), including those whose renewable sources are predominantly variable (e.g. wind and solar PV), can be readily designed to meet the key requirements of reliability, security and affordability. It also argues that transition to 100RElec could occur much more rapidly than suggested by historical energy transitions. It finds that the main critiques published in scholarly articles and books contain factual errors, questionable assumptions, important omissions, internal inconsistencies, exaggerations of limitations and irrelevant arguments. Some widely publicised critiques select criteria that are inappropriate and/or irrelevant to the assessment of energy technologies, ignore studies whose results contradict arguments in the critiques, and fail to assess the sum total of knowledge provided collectively by the published studies on 100RElec, but instead demand that each individual study address all the critiques’ inappropriate criteria. We find that the principal barriers to 100RElec are neither technological nor economic, but instead are primarily political, institutional and cultural.

Can we get 100 percent of our energy from renewable sources?

New article gathers the evidence to address the sceptics

Public release ‒ 17 May 2018

Lappeenranta University of Technology

Is there enough space for all the wind turbines and solar panels to provide all our energy needs? What happens when the sun doesn’t shine and the wind doesn’t blow? Won’t renewables destabilise the grid and cause blackouts?

In a review paper last year in the high-ranking journal Renewable and Sustainable Energy Reviews, Master of Science Benjamin Heard and colleagues presented their case against 100% renewable electricity systems. They doubted the feasibility of many of the recent scenarios for high shares of renewable energy, questioning everything from whether renewables-based systems can survive extreme weather events with low sun and low wind, to the ability to keep the grid stable with so much variable generation.

Now scientists have hit back with their response to the points raised by Heard and colleagues. The researchers from the Karlsruhe Institute of Technology, the South African Council for Scientific and Industrial Research, Lappeenranta University of Technology, Delft University of Technology and Aalborg University have analysed hundreds of studies from across the scientific literature to answer each of the apparent issues. They demonstrate that there are no roadblocks on the way to a 100% renewable future.

“While several of the issues raised by the Heard paper are important, you have to realise that there are technical solutions to all the points they raised, using today’s technology,” says the lead author of the response, Dr. Tom Brown of the Karlsruhe Institute of Technology.

“Furthermore, these solutions are absolutely affordable, especially given the sinking costs of wind and solar power,” says Professor Christian Breyer of Lappeenranta University of Technology, who co-authored the response.

Brown cites the worst-case solution of hydrogen or synthetic gas produced with renewable electricity for times when imports, hydroelectricity, batteries, and other storage fail to bridge the gap during low wind and solar periods during the winter. For maintaining stability there is a series of technical solutions, from rotating grid stabilisers to newer electronics-based solutions. The scientists have collected examples of best practice by grid operators from across the world, from Denmark to Tasmania.

Furthermore, these solutions are absolutely affordable, especially given the sinking costs of wind and solar power.

The response by the scientists has now appeared in the same journal as the original article by Heard and colleagues.

“There are some persistent myths that 100% renewable systems are not possible,” says Professor Brian Vad Mathiesen of Aalborg University, who is a co-author of the response.

“Our contribution deals with these myths one-by-one, using all the latest research. Now let’s get back to the business of modelling low-cost scenarios to eliminate fossil fuels from our energy system, so we can tackle the climate and health challenges they pose.”

Unsubsidised wind and solar now cheapest form of bulk energy

Giles Parkinson, 20 November 2018

The unsubsidised cost of wind and solar now beats coal as the cheapest form of bulk generation in all major economies except Japan, according to the latest levellised cost of electricity analysis by leading energy analyst BloombergNEF.

The latest report says the biggest news comes in the two fastest growing energy markets, China and India, where it notes that “not so long ago coal was king”. Not any more.

“In India, best-in-class solar and wind plants are now half the cost of new coal plants,” the report says, and this is despite the recent imposition of import tariffs on solar cells and modules.

The China experience is also significant. While local authorities have put a brake on local installations, causing the domestic market to slump by one third in 2018, this has created a “global wave of cheap equipment” that has more than compensated for increased financing costs caused by rising interest rates.

The cost of battery storage is also falling – so much so that in countries like Australia and India, pairing unsubsidised wind and solar with four hours of battery storage can be cost competitive with new coal or gas plants.

How rapidly can we transition to 100% renewable electricity?

Mark Diesendorf, 21 June 2018

This article focuses on the transition of the electricity industry to 100% renewable electricity together with energy efficiency.

Vaclav Smil, an expert on historical energy transitions, argues in his book that ‘the process of restructuring the modern high-energy industrial and postindustrial civilization on the basis of nonfossil, that is, overwhelmingly renewable, energy flows will be much more challenging that [sic] was replacing wood by coal and then coal by hydrocarbons.’

To question Smil’s conclusions it’s sufficient to refute the assumptions underlying his key arguments.

A more extensive critique, in Section 6 of our recent peer-reviewed paper ‘The feasibility of 100% renewable electricity’, is available free upon request from m.diesendorf@unsw.edu.au.

FoE International Report: An Energy Revolution Is Possible

A report by Friends of the Earth International (FoEI), launched a week before the 2015 UN climate summit in Paris, estimates that it would take US$5,148 billion of extra investment to generate half the world’s electricity with 100% renewables by 2030. No small amount, but to put it in perspective, FoEI points out that this is an investment equal to the wealth currently held by 0.00001% of the global population, or 782 people.

This means that the personal fortunes of the 782 wealthiest people on the planet – many of them CEOs of major corporations – could power Africa, Latin America and most of Asia with 100% renewable energy by 2030. The wealth of the richest 53 people globally could power the whole of Africa with 100% renewable energy by 2030, and the wealth of the richest 32 people could power most of Latin America with 100% renewable energy by 2030.

The report details the mix of renewable energy sources most appropriate for each region and discusses relevant technical issues regarding capacity factors, storage technologies and so on. But just as importantly, it argues that the energy revolution is necessarily a social revolution as well.

Reply to the letter from Dr. Hansen and others

Excerpt from: Jusen Asuka, Seung-Joon Park, Mutsuyoshi Nishimura and Toru Morotomi, 31 Jan 2014, ‘Reply to the letter from Dr. Hansen and others’

Several studies have been conducted in the past to determine whether this ambitious climate change target is achievable without any reliance on nuclear power. Edenhofer et al. (2010) compared low-carbon scenarios using five different energy-economy models, and identified that the additional costs needed to stop nuclear investment in 2000 would be only around 0.7% of GDP in 2100. Recently other researchers have conducted studies in consideration of the denuclearization movement after the Fukushima accident. Bauer et al. (2012), for example, state that the reductions in greenhouse gas emissions required to limit global average temperature rise to two degrees C from the pre-industrial era would be achievable for the additional cost of less than 0.1% of GDP by 2020, and less than 0.2% by 2050 without nuclear power. Duscha et al. (2013) state that denuclearization would increase global greenhouse gas emissions by 2% in 2020, but that developed countries would be able to achieve their share of the two degrees C target at an additional cost of 0.1% GDP. The same Duscha et al. (2013) reviewed other existing research, and concluded that most existing studies also indicated that ambitious greenhouse gas emissions reductions could be achieved at the additional cost of 1% GDP globally without nuclear power generation.

Energy [R]evolution: A sustainable world energy outlook 2015

Greenpeace International, September 2015, ‘Energy [R]evolution: A sustainable world energy outlook 2015’,

The Energy [R]evolution Scenario has become a well known and well respected energy analysis since it was first published for Europe in 2005. In 2015, the fifth Global Energy [R]evolution scenario was published; earlier editions were published in 200720082010, and 2012.

Greenpeace has been publishing its Energy [R]evolution scenarios since 2005, more recently in collaboration with the scientific community, in particular the German Aerospace Centre (DLr). While our predictions on the potential and market growth of renewable energy may once have seemed fanciful or unrealistic, they have proved to be accurate. the US-based Meister Consultants Group concluded earlier this year that “the world’s biggest energy agencies, financial institutions and fossil fuel companies for the most part seriously under-estimated just how fast the clean power sector could and would grow”. It wasn’t the IEA, Goldman Sachs or the US Department of Energy who got it right. It was Greenpeace’s market scenario which was the most accurate.

Avoiding blackouts with 100% renewable energy

Stanford University, 8 Feb 2018

Renewable energy solutions are often hindered by the inconsistencies of power produced by wind, water and sunlight and the continuously fluctuating demand for energy. New research by Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University, and colleagues at the University of California, Berkeley, and Aalborg University in Denmark finds several solutions to making clean, renewable energy reliable enough to power at least 139 countries.

In their paper, published as a manuscript this week in Renewable Energy, the researchers propose three different methods of providing consistent power among all energy sectors ‒ transportation; heating and cooling; industry; and agriculture, forestry and fishing ‒ in 20 world regions encompassing 139 countries after all sectors have been converted to 100 percent clean, renewable energy. Jacobson and colleagues previously developed roadmaps for transitioning 139 countries to 100 percent clean, renewable energy by 2050 with 80 percent of that transition completed by 2030. The present study examines ways to keep the grid stable with these roadmaps.

The Global Energy Assessment (GEA), launched in 2012, defines a new global energy policy agenda – one that transforms the way society thinks about, uses, and delivers energy. Involving specialists from a range of disciplines, industry groups, and policy areas, GEA research aims to facilitate equitable and sustainable energy services for all, in particular the two billion people who currently lack access to clean, modern energy.

Coordinated by the International Institute for Applied Systems Analysis (IIASA), GEA was led by some of the world’s leading energy experts in research, academia, business, industry and policy, representing both the developed and the developing world. GEA is the first ever fully integrated energy assessment that analyzes energy challenges, opportunities and strategies, for developing, industrialized and emerging economies. It is supported by government and non-governmental organizations, the United Nations Systems, and the private sector.

14. COUNTRIES WITH HIGH PERCENTAGES OF POWER FROM RENEWABLES

A 100% renewable grid isn’t just feasible, it’s already happening

Joe Romm, 22 May 2018

The ongoing debate around whether it’s feasible to have an electric grid running on 100 percent renewable power in the coming decades often misses a key point: many countries and regions are already at or close to 100 percent now.

According to data compiled by the U.S. Energy Information Administration, there are seven countries already at, or very, near 100 percent renewable power: Iceland (100 percent), Paraguay (100), Costa Rica (99), Norway (98.5), Austria (80), Brazil (75), and Denmark (69.4). The main renewables in these countries are hydropower, wind, geothermal, and solar.

new international study, which debunks many myths about renewable energy, notes that many large population regions are “at or above 100%” including Germany’s Mecklenburg-Vorpommern and Schleswig-Hostein regions, New Zealand’s South Island, and Denmark’s Samsø island. In Canada, both Quebec and British Columbia are at nearly 100 percent renewable power.

Last summer, China’s State-run Xinhua News Agency reported that “Qinghai Province has just run for seven straight days entirely on renewable energy … only wind, solar and hydro.” This was part of a test by the country’s State Grid Corporation to show a post-fossil-fuel future was practical.

Bloomberg New Energy Finance (BNEF) has projected that by 2040, Germany’s grid will see nearly 75 percent renewable penetration, Mexico will be over 80 percent, and Brazil and Italy will be over 95 percent. BNEF was not looking at what could theoretically happen by mid-century if countries pushed as hard as required by the Paris Climate Accord. They were just looking at business as usual over the next two decades.

A study out earlier this month found, “Indonesia has far more than enough pumped hydro storage sites to support a 100% renewable electricity grid.” Storage is one of the most straightforward ways to integrate wind and solar power into the grid, to account for the times when the wind doesn’t blow or the sun doesn’t shine. … And pumped hydro is but one of many strategies for integrating more renewables into the grid.

15. CANADA

Canada could go 100% renewable by 2035 if its government gets serious

Katie Valentine, 24 March 2015

Canada can be a world leader in emissions reductions and renewable energy use, but only if its federal government decides to take climate change seriously, according to a new report.

The report, published by 70 Canadian academics, looked at Canada’s potential to shift its electricity production to renewable sources and cut its emissions. It found that the country could get 100% of its electricity from low-carbon sources like wind, solar, and hydropower by 2035 and reduce its greenhouse gas emissions by 80% by 2050. To achieve these goals, the report recommended that the federal government implement a nationwide price on carbon and eliminate subsidies to Canada’s fossil fuel industry – particularly, its tar sands industry.

Unsubsidised wind and solar now cheapest form of bulk energy

Giles Parkinson, 20 November 2018

The unsubsidised cost of wind and solar now beats coal as the cheapest form of bulk generation in all major economies except Japan, according to the latest levellised cost of electricity analysis by leading energy analyst BloombergNEF.

The latest report says the biggest news comes in the two fastest growing energy markets, China and India, where it notes that “not so long ago coal was king”. Not any more. …

The China experience is also significant. While local authorities have put a brake on local installations, causing the domestic market to slump by one third in 2018, this has created a “global wave of cheap equipment” that has more than compensated for increased financing costs caused by rising interest rates.

China could get 85% of its electricity and 60% of total energy from renewables by 2050, according to government agencies.

Emissions will peak by 2025 if wind, solar and bioenergy are rolled out quickly, finds the report led by the China National Renewable Energy Centre claims.

In a “high renewable” scenario, the country’s coal use would peak in 2020 and its greenhouse gas emissions by 2025 – five years ahead of target.

France: 2018 report

France’s environment ministry ADEME released a report finding that France will save €39 billion (US$44.5 billion) if it refrains from building 15 new nuclear plants by 2060, and instead replaces reactors with renewable energy sources.

France should spend €1.28 trillion over the next four decades, the report states, mostly on clean power production and storage capacities, networks, and imports. If it does this, France would progressively shut down its 58 reactors and renewable energy would comprise 85% of electricity generation by 2050 and 95% by 2060, up from 17% last year.

Bloomberg reported: “Falling costs means that photo-voltaic facilities won’t need subsidies from 2030, nor will onshore wind from 2035, the [ADEME] report said. That’s assuming that EDF halts 30 percent of its reactors after 40 years of operation and an additional 30 percent when they turn 50. Otherwise, surplus production capacity would undermine the economics of both nuclear power and renewables, ADEME said. The study doesn’t take into account the impact on jobs, industry and the environment. However, “we’re expecting job creations in renewables and energy efficiency to largely make up for job losses in the nuclear industry,” said ADEME Chairman Arnaud Leroy.”

France: 2015 report

A 2015 report by ADEME, a French government agency under the Ministries of Ecology and Research, shows that a 100% renewable electricity supply by 2050 in France is feasible and affordable. For an all-renewables scenario, the report proposes an ideal electricity mix: 63% from wind, 17% from solar, 13% from hydro and 7% from renewable thermal sources (including geothermal energy). The report estimates that the electricity production cost (currently averaging 91 euros per MWh) would be 119 euros per megawatt-hour in the all-renewables scenario, compared with a near-identical figure of 117 euros per MWh with a mix of 50% nuclear, 40% renewables, and 10% fossil fuels.

Future bids for renewable projects to have 50 pc manufacturing component: R K Singh

June 25, 2018

Union Power Minister R K Singh said, “We will add 175 GW of renewable energy by 2022. We have already added around 70 GW of renewable energy that is solar and wind and around 40 GW is under implementation.”

On lowering emission goals, he said, “We have pledged in 2015 that by 2030, 40 per cent of our installed capacity will come from renewables.”

The minister said that with the addition of large hydro power of 45 GW to 70 GW of renewables, it has already crossed 30 per cent, and by 2030, about 53 or 55 per cent of installed power generation capacity will be renewables.

Talking about investment in clean energy in India, he said about USD 42 billion investment has come in renewables in the last four years which was done by facilitating the market and India did not invest except in the transmission.

On India’s household electrification programme, he said, “In the sphere of power and renewables, we are engaged in massive expansion programme. We are adding about 40 million electricity consumers. We have already added about 7.5 million consumers till date. We have added 100,000 km lines to transmission country.”

Unsubsidised wind and solar now cheapest form of bulk energy

Giles Parkinson, 20 November 2018

The unsubsidised cost of wind and solar now beats coal as the cheapest form of bulk generation in all major economies except Japan, according to the latest levellised cost of electricity analysis by leading energy analyst BloombergNEF.

The latest report says the biggest news comes in the two fastest growing energy markets, China and India, where it notes that “not so long ago coal was king”. Not any more.

“In India, best-in-class solar and wind plants are now half the cost of new coal plants,” the report says, and this is despite the recent imposition of import tariffs on solar cells and modules.

Realizable solar potential in India is 110 GW to 144 GW by 2024

September 2014

A recent BRIDGE TO INDIA analysis suggests that India’s realizable solar potential is 110 GW to 144 GW by 2024. Solar could contribute 10%-13% to India’s grid power supply by 2024 without destabilizing the grid. 26-35 GW is the potential for small rooftops (“bees”), 31-41 GW for commercial rooftops (“pigeons”), 32-42 GW for utility scale plants (“horses”) and 21-27 GW for GW-scale plants (“elephants”)

A Bloomberg New Energy Finance (BNEF) 2018 report found that the cost of wind and solar power has declined dramatically over the past year in India, well beyond the global average. According to BNEF: “Taking India as an example, BNEF is now showing benchmark LCOEs [levelized costs of electricity] for onshore wind of just $39 per MWh, down 46% on a year ago, and for solar PV at $41, down 45%. By comparison, coal comes in at $68 per MWh, and combined-cycle gas at $93. Wind-plus-battery and solar-plus-battery systems in India have wide cost ranges, of $34-208 per MWh and $47-308 per MWh respectively, depending on project characteristics, but the center of those ranges is falling fast.”

Bloomberg New Energy Finance, 28 March 2018, ‘Tumbling Costs for Wind, Solar, Batteries Are Squeezing Fossil Fuels

Research released by Greenpeace India in December 2017 found that at least 65% of India’s coal power generation in financial year 2016 – representing 94 GW of installed capacity – was being sold to distribution companies at a higher cost than power from new renewable energy projects. The analysis showed that replacing the most expensive coal power plants with electricity generated by solar PV and wind would save consumers up to 54,000 crores (US$8.3 billion) annually. Just replacing older, expensive plants – those older than 20 years – would still yield 20,000 crore (US$3 billion) in reduced power purchase costs annually.

Study: wind and solar can power most of the United States
Wind, solar, and storage could meet 90–100% of America’s electricity needs
2018 study: Wind and solar PV could meet 80% of US electricity demand

A new study finds that wind power and solar photovoltaics could by themselves meet 80 percent of all U.S. electricity demand. “Five years ago, many people doubted that these resources could account for more than 20 or 30 percent,” co-author Steven Davis of the University of California at Irvine (UCI) explained in a news release. So, “the fact that we could get 80 percent of our power from wind and solar alone is really encouraging.”

From the news release: “But beyond the 80 percent mark, the amount of energy storage required to overcome seasonal and weather variabilities increases rapidly. “Our work indicates that low-carbon-emission power sources will be needed to complement what we can harvest from the wind and sun until storage and transmission capabilities are up to the job,” said co-author Ken Caldeira of the Carnegie Institution for Science. “Options could include nuclear and hydroelectric power generation, as well as managing demand.””

Also from the news release: “We looked at the variability of solar and wind energy over both time and space and compared that to U.S. electricity demand,” Davis said. “What we found is that we could reliably get around 80 percent of our electricity from these sources by building either a continental-scale transmission network or facilities that could store 12 hours’ worth of the nation’s electricity demand. The researchers said that such expansion of transmission or storage capabilities would mean very substantial – but not inconceivable – investments. They estimated that the cost of the new transmission lines required, for example, could be hundreds of billions of dollars. In comparison, storing that much electricity with today’s cheapest batteries would likely cost more than a trillion dollars, although prices are falling.”

Comments from Think Progress: “It’s especially encouraging for two additional reasons. First, the price of solar and wind have been dropping rapidly. Second, the study only examined how wind and solar could power the grid. In doing so, it found these two sources alone could provide 80 percent of the power. This still leaves 20 percent that could be provided by a variety of alternative types of carbon-free power. And in terms of alternate carbon-free power sources, hydropower already provides 6.5 percent of U.S. power while geothermal and biomass together add another 2 percent. All of those can be expanded.”
