“A 100% renewable economy is 100% guaranteed to pay for itself over time.”
~ Simon Butler, in a talk presented at the conference ‘Climate Change Social Change’ in Sydney, Australia, on 11 May 2013
The vision of zero carbon – stopping all emissions from fossil fuel by using 100% renewables to supply society with energy – is often met with the “yes, but…”. People are asking, “Yes, sounds nice, but is it realistic? Is it possible?”. The answer to this question, in short, is a loud and clear: “Yes! It is absolutely possible. And a handful of countries have proved it already!”
On this page you will find links to reports and experts who provide answers to the question. You will learn that what primarily is the challenge here is that we urgently need to remove the smokescreen of doubt which to a large extent has been created by the deliberate spin from the fossil fuel industry which has a strong commercial interest in delaying the transition.
“It feels like a secret because it seems like nobody knows it. It is this: we can run the planet on 100% renewable energy. The science and technology says we can do it – 100% wind, water and sun. No fossil fuels necessary. No more fracking, no more mountaintop removal, no more tar sands. We have the technology now. What we don’t have right now is enough people and politicians acting to create our new world.”
Josh Fox director
“We know how to get all of the energy we need without using dirty or dangerous fuel sources. It is no longer a question of whether we can – but of whether we will”
Michael Brune Executive Director, Sierra Club, USA
Introduction to the topic: 100% renewables
Regardless of what any expert might say, the bottom line is that this should simply be a “100% Yes!” because even if it should turn out to be impossible to reach the 100% renewables goal in the first or second decade, it will be going to be possible eventually, in one of the following decades. We know that. If we want it to be possible, we will make it possible.
It is as simple as that.
The rest — the current confusion, the doubt, the opinions which keep delaying us in this matter — is nothing but the industrial dinosaurs addicted to oldfashioned fossil fuels trying to protect their investments and their ability to squeeze as many drops of profits out of their assets as possible.
American climate activist Al Gore and his Climate Reality Project formulated it like this:
“If a doctor said your loved one required major surgery to survive, but it would be very difficult to complete, would you take ‘No, it’s too hard’ for an answer?
We didn’t think so. So when climate deniers claim, “Shifting over to clean energy would be too hard and shut down the economy,” we here at The Climate Reality Project politely beg to differ.
Maybe you do too.
We put a man on the moon. We eradicated smallpox. We built a computer that can fit in your pocket. These accomplishments – and so many more – were possible because groups of like-minded, passionate individuals (much like you) saw the future they wanted and worked hard to make it happen.
Big Oil and Big Coal spread big lies claiming that changing to clean energy would cause economic turmoil and finding sustainable solutions to the climate crisis ‘is too hard’.
But that’s just not the case. We’re already seeing that shifting to clean energy is a whole lot easier than they think. In 2012, renewables accounted for slightly over half of new electric generating capacity worldwide.
In the U.S, we’re installing a new solar power system every four minutes. Meanwhile, global investment in clean energy topped out at US$244 billion worldwide. In 2009, global investment was just $178 billion – so in just three years that’s a 37 per cent climb, and nearly ten times the investment made in 2004.”
5.7 million jobs
There is a vast industry being built on tapping energy from sunshine, wind, rivers, sea waves, or heat from the ground, and many are actively encouraged by governments, CSIRO, universities and commercial entities. Currently global renewables sector tops 5.7 million jobs, according to the United Nations Environment Programme.
But they all require building more stuff, using the available fossil energy to do it, and with the current technology it does not look as if they will be able to produce the amounts of energy the world demands. Many — Nicole Foss is one of them — are saying that using less energy and less stuff is the only solution.
According to some scientists and researchers, it is a naive misconception so think that “the only thing we need to do is to replace fossil fuels with renewable energy”. Because it won’t be possible just like that. For instance, the Danish author of the books ‘Re-think’ (‘Om-tanke’) and ‘New energy’ (‘Ny energi’) Klaus Illum wrote in a comment about the report by Armstrong Asset Management called ‘Entering a New Phase of Growth: Renewable Energy in SE Asia’ which was published in May 2012:
“Running a steadily growing world economy with less and less and eventually no consumption of fossil fuels implies — if it could be done — a comprehensive reconstruction of all the energy supply infrastructure which the current economy is based on.
An allegory: You have built a skyscraper with steel in all its structures. It cannot be converted into a skyscraper held together by wood and brick. With wood and brick you simply can not build skyscrapers. Similarly, societies whose energy conversion is based on renewable energy sources will have to be built completely different — technically and economically — than the present.
Therefore, it is irrelevant to compare prices of electricity from wind turbines and solar cells with prices for electricity from power plants fired by fossil fuels, unless the electricity generation in wind turbines and solar cells only contributes with a marginal contribution to the total electricity supply — in which case the comprehensive reconstruction of the infrastructure isn’t needed. And in this case, electricity production based on renewable energy sources can only provide a financial return to the owners of these renewable energy plants, it can not solve the climate change problem — which is what we would be interested in.
Surely, there is money to be made by building wind turbines to cover part of the electricity consumption in the factories that produce oil-powered cars, in the shipyards buildings that build fossil fuel-driven oil and LNG tankers and bulk carriers for coal and feed transport across the oceans, and huge container ships to transport finished goods around the world in a growing offshore and shale-fracking oil and gas extraction industry. But it does not change the course of the fossil fuel societies’ heading towards their own collapse.”
However, an increasing number of experts and authors argue that a transition to 100 per cent renewables within just a few decades is possible, but they are also aware that it will not happen without an extraordinary and unusual global commitment from the citizens of this planet — with the kind of mobilisation which so far has only been seen in wartime, like it happened during the Second World War, for instance.
Below you will find a list of articles which make good reading if you would like to dig deeper into these questions of not whether but when the transition to 100 per cent renewables is going to be completed. Will it be possible in the kind of speed that is required in order to establish climate safety?
At present the answer to the question of speed is still “blowing in the wind”, but we should also remember that there are companies who have a strong economic interest in keeping it blowing up there there as long as possible. And that these companies are getting away with paying leading politicians millions and millions of dollars to have them help them with that agenda.
One could argue that if we simply started the process with full force now, what would we have to lose? We would be sure to reach the goal eventually — so what are we waiting for?
Price: Three per cent of world GDP a year
“Considering the gravity of the climate crisis, it’s maddening to think how relatively easy it would be to take serious climate action. We’d need about 1.5 million wind turbines around the world to replace coal burning for energy — not too hard when you consider that the car industry alone, working at two thirds of its capacity, made 65 million cars worldwide in 2008.
Just the unused manufacturing capacity of this single industry would be enough to build all those wind turbines in a decade.
In 2011, environmental consultants Ecofys released a report that said the world could have 100% renewable energy in 40 years. It said this would cost about 3% of world GDP a year, but would lower energy costs by about $5.7 trillion a year by 2050.
Of course, we’re told that there isn’t enough money to pay for this kind of thing. We’re not supposed to realise that half of all global trade passes through offshore tax havens, which control a third of the world’s wealth.”

As nation states delay, these cities have ambitious renewable energy goals.
Running on 100% renewable energy – how realistic is it really? GreenMatch made this short and informative video.
“According to many researchers a world powered entirely by renewables such as wind, solar, hydro etc, is not unreasonable at all. In fact, they predict that we can achieve this by 2050. In the past, many countries have made it their mission to go all-renewable, and some have been very successful. Today, more than five countries have achieved their goal, and many more vow to go 100% renewable by 2050.”

Running On 100% Renewable Energy – How Realistic Is It Really?
In Australia, the ACT government shows leadership in the renewables sector
In November 2013, the Government of the Australian Capital Territory (abbreviated ACT) legislated an ambitious target to source 90 per cent of the Territory’s power from renewable sources by 2020, a quarter which will come from wind energy.
ACT’s scheme demonstrates that the cost of transitioning to clean renewable energy is entirely manageable: the cost of their ambitious policy is about $4 per household per week which then is offset by about $4 per household per week due to energy efficiency schemes that are currently being deployed. The ACT Government helps Canberran citizens reduce their energy consumption and use more renewable energy.
“What I’m most excited about is showing people that this is possible. People can’t do what they can’t imagine, and the opportunity here in the ACT is to demonstrate what can actually be achieved, and what you can do and that it is affordable and that it is achievable, and that if a small place like the ACT can do it, surely the rest of Australia can,” Simon Corbell, ACT’s energy minister told ABC Radio.
“Addressing climate change requires a global commitment to stabilise greenhouse gas concentrations in the atmosphere, and is a shared responsibility that all countries and communities must embrace,” Mr Corbell is quoted as saying in a press release released in November 2013.
The goal is to have a 40 per cent reduction of 1990 carbon emission levels by 2020, and 80 per cent reduction by 2050.

CSIRO says Australia can get to 100 per cent renewable energy
“A 100 per cent renewable grid is possible”
The Alternative Technology Association’s report ‘100% Renewable Energy Grid – Feasible?’ examines the possibility of a fully renewable energy grid in Australia and concludes that such a grid is doable and can play an important part in our commitments to fight climate change. A fully renewable electricity grid would provide long-term economic, climate and social benefits for Australia, according to the discussion paper published on 9 December 2016.
“We found all experts agree that a 100% renewable grid will be reliable and stable, as long as it uses an appropriate mix of renewable generation sources, energy storage and upgraded infrastructure,” said Andrew Reddaway, the paper’s author and ATA energy analyst.
During periods of calm, cloudy weather electricity could be sourced from sunny or windy parts of the country and supplemented with energy stores such as hydroelectric dams, molten salt heat storage, batteries, renewable gas and stockpiles of pelletised woody waste.
“This grid would be robust, with smarter renewable generators and batteries automatically injecting extra electricity when required for grid stability,” Mr Reddaway said.
“Similarly, smart appliances would detect disturbances in the grid and independently adjust their power level to compensate.”

Go 100% renewable, create three million new jobs and save $520 billion a year
“This report proves once again that going 100% is good for the economy. Technologies like wind and solar can not only save money in energy bills, but also make a good investment. Going 100% renewable just makes good business sense.”
Emily Farnworth, Campaign Director of RE100 at The Climate Group
Adopting targets to go 100% renewable could save the world’s biggest economies a combined US$520 billion each year and generate a combined total of three million new jobs, according to a new report from the New Climate Institute and Climate Action Network.
As well as sidestepping the high costs associated with imported fossil fuels by shifting to 100% renewable energy by the year 2050, these economies will also avoid the “severe, widespread, and irreversible impacts” the International Panel on Climate Change forecasts will happen if we increase global warming 2°Celsius degree above preindustrial levels.
Australia could source 100% of power from renewables by 2050, report finds
A new report sets out what governments need to do. It says all Australia’s energy needs could come from renewables by 2050, without massive costs or depressing economic growth.
A WWF report produced in collaboration with the Australian National University argues Australia could source 100% of its power from renewables by 2050 – without incurring massive adjustment costs or depressing economic growth – if there were clear and stable national policy settings to support investment in renewables.
The city of Vancouver is an example of a big city that recently committed to run 100% on renewables for power, heating and transportation within 20 years. New studies have also been released recently showing the US can get to 100% renewables by 2050 at marginal extra cost.

Major new report: Low-carbon society benefits citizens and business
A major report shows that policies to maintain a safe and secure climate will mean a better quality of life for millions of people around the world. The study, spearheaded by leading names in finance, business and politics – including feted UK economist Lord Nicholas Stern and Former Mexican President Felipe Calderon – dispels the myth that action on climate change comes at the cost of people’s living standards. Instead it underlines that better jobs, cleaner air, and happier, healthier communities are all consequences of ambitious policies to cut carbon.
“This report lays out how countries across the world can reduce the risks of climate change and achieve high-quality, resilient, and inclusive economic growth.”
Launched at the UN headquarters in New York just one week before the UN Climate Summit, the ‘Better Growth, Better Climate: The New Climate Economy Report’ highlights that a major transition is already taking place – boosted by rapid technological innovation and fresh investment in infrastructure.
It offers yet more proof that there are no arguments left in favour of sticking to outdated fossil-fuels and plenty of good reasons for governments and leaders from business and finance to embrace the transition to a cleaner, healthier society run on renewable energy sources.

He goes further and says he and a team at University of NSW have shown, over the last few years, that it is technically and economically feasible for Australia to go to 100% renewables in its electricity supply. He even suggests the transition to 100% renewables could be made without additional cost if existing fossil fuel subsidies were transferred to renewables.

100% Australian Renewable
What does 100% renewable electricity for the whole of Australia look like? Australian Energy Market Operator, commissioned by the Australian Federal Government, has been modelling for what a 100% renewable national electricity grid for Australia would look like.
A community goes 100% renewable
Craig Morris took a trip to one of the country’s numerous 100% Renewable Villages, which are increasingly covering all of their electricity and heat demand from local renewables and becoming exporters to neighboring cities.
“While most other countries debate how quickly they should be moving to decarbonise the economy, the overall theme in Australia is how slowly it should be done.”
“A 90 per cent renewables target would cost no more to consumers if tied in with energy efficiency and other measures. It’s a shame that no other politician from a mainstream party is talking in those terms on a national scale.”
“The Australian Energy Market Operator’s 100% renewables scenario estimates wholesale cost of electricity from a system based largely around wind, solar, geothermal and biomass would cost around $110/MWh.”

Renewables future no more costly than fossil fuels
A renewables future will be no more costly than the largely fossil fuel alternative. By Giles Parkinson
“We are regularly told by conventional utility companies, many politicians and commentators that energies such as solar and wind are hopelessly expensive and reliant on enormous subsidy. But this is simply wrong,” wrote the managing director of AEA Solar GmbH, Ashley Seager, in the British newspaper The Guardian.
“Not investing in renewables only makes sense if you don’t want to meet our emissions targets – if you tear up the Climate Change Act,” chief executive of the British Committee on Climate Change David Kennedy told the Guardian. His committee provides independent, evidence-based advice to the UK Government and Parliament.

“The new report from the British Committee on Climate Change arguing that investing in renewable energy would eventually save consumers a lot of money is spot on,” wrote Ashley Seager.
This report shows that there is a clear benefit in committing to invest in low-carbon generation through the 2020s. The Government recently published a package of measures which would support investment in low-carbon technologies in the years up to 2020. The report considers how best these policies might be advanced particularly in the light of the opportunities presented by the exploitation of shale gas. It also takes account of the highly uncertain investment conditions relating to the period beyond 2020.

Not all renewables are created equal
Remaking the energy economy cannot be accomplished overnight and thus there will be disagreements over strategies and tactics among activists. By Tom Butler
“The main problem of the energy situation today in Europe is the massive subsidies – still in 2013 – going to fossil fuels and nuclear. If that was corrected and with a properly functioning electricity market there would be no discussion of what choice policy makers would make for the energy mix. But even without such a correction, wind energy is already cheaper than nuclear, and in an increasing number of locations already cost competitive with new gas and coal.
Wind energy does not have to be bought and transported into Europe from sometimes unreliable suppliers. Paying higher and higher bills for importing fossil fuels is not my idea of security of supply.
A 2030 target for renewable energy is the best way to make all renewables more cost-competitive, would create jobs and huge investment in Europe – rather than in some fossil-fuel producing country. It would ensure that the world-leading European wind industry grows and flourishes even more.
It is time for BusinessEurope to stop representing the interests of fossil fuel exporting regimes and start representing the interests of European businesses.”

A road map to 100% renewables
Friends of the Earth’s road map to 100% renewables
“With the Australian government doing everything in it’s power to dismantle action on climate change, we need state-based leadership like never before,” writes Friends of the Earth. “Moving to 100% renewables here in Victoria is achievable. It will generate thousands of jobs, share income and opportunity around much of the state, and profoundly reduce our contribution to global warming.”
Can the world convert to total renewable energy by 2050?
Interview with Stanford University’s professor Mark Jacobson by Richard Blackwell published in The Globe and Mail on 3 January 2016:
In 2009, Stanford University engineering professor Mark Jacobson outlined a plan for the world to get all its energy – including transport and heating fuel and electricity – from wind, water and solar resources by 2050.
Considered radical at the time, the model has been fleshed out to provide details for 139 countries and is now seen as far less extreme than it once was. The conversion would not only eliminate most greenhouse gas emissions, Mr. Jacobson says; it would dramatically improve human health and create millions of new jobs. He spoke recently to The Globe and Mail’s Richard Blackwell.
Many people would suggest your proposal is radical and impractical. Is it?
I think it is actually mainstream now. At the Paris conference, they were talking about 100-per-cent renewable energy. In the United States, presidential candidates on the Democratic side have embraced it.
Does that reflect a major change in attitude since you first proposed this in 2009?
It was definitely radical in 2009, and even through 2013 and partly in 2014. Most of this transformation has taken place in people’s minds in the last year. The goal to get to 100-per-cent renewable energy has gathered a huge momentum.
Are you happy with the Paris agreement, which is fairly vague in how it will get to its goals?
It is certainly positive. It is not enough to really address the problem full on. But in terms of what is possible at an international level – trying to get 195 countries to agree – it’s a good start. But each individual country can do a lot more than what that agreement would indicate. Not only can, but should, because it will be to their own benefit.
Is converting transport – cars, planes and other vehicles – the most difficult part?
I think it is easier to transform transportation than anything else, because the turnover time of a vehicle is usually around 15 years. The turnover time of a power plant is between 30 and 40 years. The technology is there for ground transportation right now … although less so for long-distance ships and planes. Aircraft are probably the hardest to change. Everything else we could transform within 15 to 20 years.
What technology would allow the conversion of aircraft to renewables?
We propose cryogenic hydrogen, which is just hydrogen at a low temperature. It was used to propel the space shuttle. It has been tested and it works.
Why do you not have any nuclear power in your models?
It has disadvantages compared to wind, water and solar, and it is not necessary. It might be better than gas or coal, but it still results in nine to 25 times more carbon emissions and air pollution than wind power, per unit of energy generated.
Also, 1.5 per cent of all nuclear reactors built have melted down seriously. And countries have secretly developed weapons under the guise of civilian programs. Then there are radioactive waste issues that are not resolved. And they cost three to four times more right now than wind power and two to three times more than utility-scale solar. There is really no advantage to using it.
Some people oppose hydro power because of the carbon footprint when large projects drown forests. Is that an issue?
We have zero new hydro. It is all existing hydro, so there is no new footprint of any kind.
Isn’t there a physical and environmental footprint from building so much new wind and solar power?
Keep in mind that we are also subtracting all the footprint related to gas, coal, oil and nuclear. There are 2.3 million gas wells spotting the Great Plains of the U.S. and Canada. Well pads, roads and storage facilities take up an area the size of the state of Maine. We would be subtracting that, and all the coal mines, all the oil refineries and the oil wells.
The new physical footprint for everything, worldwide, would be about 0.3 per cent of the world’s land area. The spacing [between wind turbines and solar panels] is another 0.6 per cent of the world. And most of that spacing can be used for agriculture.
What about concerns over materials used in solar panels and wind turbines?
There is an environmental impact for mining [those materials]. But it is a one-time [impact] for each device. With fossil fuels, you need to keep mining continuously. The solar panel footprint is trivial in comparison to the fossil-fuel footprint.
How do you convince countries with big oil and gas industries, like Canada, that this shift is a good idea?
It is [a matter of] information. If people realize that they are going to make and save a lot more money by converting, then the transition would go naturally. If the benefits are clearly laid out, versus the costs, it is a no-brainer for most people.
What about all the people employed in the oil and gas industries who may lose their jobs?
If you convert, you create an additional 22 million jobs worldwide. Sure, you would have to retrain some people, maybe a lot of people in oil and gas, but there are jobs that will be available, both in construction and permanent operation jobs.
Which countries did you find will have the most difficulty to shift to an all-renewable energy economy?
The ones that were the hardest were the smallest – such as Singapore and Gibraltar. They have pretty high populations but not much area, so it is hard for them to produce all their own energy and be energy independent. In Singapore, they will have to transfer some energy from Malaysia. Gibraltar will probably get it from Spain.
Most countries have either a lot of solar or a lot of wind, or a mixture of both. There weren’t any countries that we couldn’t do it in. In some countries, it is more of a political issue because they are war-torn.
Is energy storage going to be a key factor in making this work?
You do need a lot of storage, but it is low-cost storage: pumped hydroelectric storage, concentrated solar power with storage, and heat stored in water and rocks. Combining those with demand response and some hydrogen, which is also a form of storage, will solve the problem.
Is 2050 still a practical date to achieve that goal?
Our goal is to get to 80 per cent by 2030 and 100 per cent by 2050. It is certainly technically and economically practical. Whether it is politically tractable is a different question.

“Sounds like a big task – all those wind farms and solar plants and power lines? Could we do it? Can we afford it? Yes we could, and yes we can.
The investment in this transition to zero emissions electricity is around 3% of GDP over 10 years, or $370 billion. This is about as much as we spend on insurance over the same time. For an average household this would mean an increase to their electricity bill of $8 per week, with a 100% renewable electricity grid to show for it.”

How to power 100 per cent of the planet with renewable energy by 2030
In 2009, Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University, and Mark A. Delucchi a research scientist at the Institute of Transportation Studies at the University of California wrote an article in Scientific American where they outlined a plan to power 100 per cent of the planet with renewable energy by 2030. They calculated it would require 3.8 million large wind turbines, 90,000 solar plants, and numerous geothermal, tidal and rooftop photovoltaic installations worldwide.
The cost of generating and transmitting power would be less than the projected cost per kilowatt-hour for fossil-fuel and nuclear power, but shortages of a few specialty materials, along with lack of political will, loomed as the greatest obstacles, they wrote.

Tokelau turned off the last of its diesel generators in October 2012. In their place, they switched on their new solar plants, making Tokelau the first country in the world to become 100% renewably-powered.
“I woke up before sunrise that day, excited about the history Tokelau was making,” said Mikaele Maiava, a spokesperson for the youth-led climate change action network 350 Pacific:
“My whole village made its way to the site of over 100 solar panels — we could see the many hours of hard labor that had gone into this project. As we counted down to the switch, I could feel future generations smiling at us and thanking us. Our children’s future suddenly looked brighter because we had the vision (and perseverance) necessary to get off fossil fuels and switch to 100% renewable energy.”
Maiava called on the rest of the world to do the same:
“We want to show the world that people from countries and cultures everywhere are standing with us — the Pacific Warriors — in the fight against climate change.”
