When governments fall short, ordinary people can spark extraordinary change. Nowhere is this more evident than in Denmark, where citizens and community groups took the lead in a wind energy revolution that helped set the country on a path to phase out fossil fuels entirely. Decades ago, while the Danish government was hesitating on clean energy, locals banded together to build wind turbines on their own. The result? Denmark today generates 84% of its electricity from renewables, with 54% being from wind. Denmark’s proved that the clean energy revolution can be powered by the people.
People-powered wind revolution
In the 1970s, Denmark faced an energy crossroads. The government was considering nuclear power, but ordinary Danes and NGOs had different ideas. A vibrant anti-nuclear movement emerged with the iconic slogan “Nuclear power? No thanks” and activists didn’t just protest, they offered a solution. Environmental groups and citizens began advocating for wind energy as the safe, clean alternative.
In fact, some communities simply went ahead and built turbines themselves. In 1978, a group of teachers and students constructed a then record-breaking wind turbine at Tvind, proving that local ingenuity could achieve what big utilities hadn’t. This DIY turbine, built by citizens on a shoestring, became a symbol of what grassroots innovation could do.
This early citizen leadership laid the foundation for Denmark’s wind power boom. By the late 1970s and early ’80s, rural communities and eco-minded cooperatives were installing wind turbines to power their towns and farms. Residents pooled funds to erect turbines, sharing both the electricity and the profits. By 1996 there were around 2,100 wind energy cooperatives across Denmark. These co-ops gave tens of thousands of people a direct stake in clean energy.
These citizen-led projects moved forward at a time when government support was modest. While officials slowly came around to renewables, communities were already proving wind power’s viability on the ground. By 2001, over 100,000 Danish families belonged to wind cooperatives that had installed 86% of all the nation’s turbines . In other words, regular people owned the majority of Denmark’s wind infrastructure, long before big energy companies jumped in. This bottom-up momentum not only built turbines, it built public pressure that pushed Denmark’s policies to be greener. Community and NGO leadership filled the gap when the government wasn’t doing enough and ultimately nudged the government to step up as well.
The Middelgrunden Model
A shining example is the Middelgrunden offshore wind farm near Copenhagen. Commissioned in 2000, this 40 MW facility is co-owned by the city’s utility and a cooperative of over 8,500 locals. Citizens invested approximately €23 million, covering half the project’s cost. Through extensive public consultations, the project garnered widespread support, turning potential opposition into pride. Investors saw returns of 6-7% annually, recouping their investments within eight years.
When the people lead a fossil fuel phase out
Middelgrunden was not a one-off, it was a model. Inspired by its success, more community wind projects blossomed across Denmark in the 2000s. In fact, Denmark’s government eventually adopted policies to cement community ownership in all new projects. A 2008 renewable energy law (implemented around 2011) requires that at least 20% of any new wind farm be offered to local residents for purchase. This policy ensures that as wind power expands, communities get a slice of the benefits.
Thanks to decades of grassroots action, Denmark has transformed from a fossil-fuel dependent nation into a global renewable energy leader. Wind now generates over half of Denmark’s electricity and much of that power belongs to the people. By 2016, more than 50% of Denmark’s wind capacity was owned by citizens or co-ops, not corporations.
This people-powered approach also fueled economic prosperity. Denmark became a wind manufacturing giant, with renewables employing around 2% of its workforce and generating billions through exports. Denmark’s transition shows that when the clean energy revolution belongs to the people, climate action and community prosperity go hand in hand.
Australia: ready for a community energy revolution
Looking at Denmark, you might think Australia, with our endless sun, wind and wide-open spaces would be following a similar path. We certainly have the natural potential to be a renewable energy superpower. Yet Australia’s renewable journey has been slower and bumpier, often held back by the influence of fossil fuel interests. While Denmark races toward 100% green electricity, only a bit under 40% of Australia’s electricity currently comes from renewables. And we remain one of the largest exporters of coal and gas. In many ways, Australia today is where Denmark was decades ago: the government is talking about climate solutions, but not acting fast enough. This is where Aussies can learn from the Danish playbook.
The good news is Australians are already stepping up. In the absence of strong federal action in years past, communities, NGOs, and everyday families have taken initiative. Just look at our rooftops: as of 2024, nearly 1 in 4 of Australian households have installed solar panels on their homes, the highest uptake of rooftop solar in the world. That’s millions of Australian families who decided to generate clean power on their own, often long before governments provided any substantial incentives.
Community energy projects are also gaining momentum here. Just look at Hepburn Wind in Victoria, Australia’s first community-owned wind farm. In the late 2000s, locals near Daylesford didn’t wait around for big energy companies to act. They came together, formed a cooperative, and raised nearly $10 million from 2,000 members to make their vision real. By 2011, two turbines were spinning, generating enough clean electricity to power over 2,000 homes.
Hepburn Wind shows what’s possible when communities take the lead. Like Denmark’s early wind pioneers, these locals proved that people-powered renewables can thrive in Australia too.
The power of communities: from Denmark to Down Under
The protest sought to increase pressure on the Australian government to commit to a timeline for a fair and fast phase out away from all fossil fuels, starting with no more coal and gas.
Australia is the world’s third largest exporter of fossil fuels, and the Newcastle Port is the world’s largest coal export port. On the final day of the “protestival”, 170 people were arrested while out in their kayaks blocking the channel to prevent coal ships from passing, successfully forcing one coal ship to turn around.
Danish residents didn’t wait for permission or perfect policies, they organised, invested, and built the future they wanted to see. In doing so, they dragged their leaders along with them and reaped rewards for their communities. Australians have that same spirit. We’ve seen it in the rooftop solar boom, in grassroots campaigns to stop new coal mines, and in local renewable projects that put people and the planet first.
The climate crisis demands urgent action, but Denmark shows that action can begin at the grassroots and turn into a national triumph. It’s a hopeful reminder that even if our leaders are slow, we don’t have to be. When communities lead, politicians will follow. As the Danes have shown, a greener future is not just up to governments or big companies, it’s in our hands. It’s time for Australia’s own people-powered energy revolution.
Sign the petition to demand no new fossil fuels and help spark the change we need.
Can Australia catch up? Top lessons from Denmark’s people-powered energy revolution
The “data-centre boom” is driving a surge in gas investment in the US, pushing its fossil-power spending ahead of China, according to the International Energy Agency (IEA).
A rapid expansion of data centres across the nation is at the heart of the US tech sector’s plans to continue “dominat[ing]” the global artificial intelligence (AI) industry.
High demand for electricity to power these data centres has led to companies rushing to build new gas-fired power plants across the country.
This trend, combined with “soaring” gas-turbine prices, drove a threefold increase in US gas‑power investment in 2025 – and the IEA expects this to continue throughout 2026.
As the chart below shows, Chinese investment in coal- and gas-fired power is expected to drop this year, amid domestic policy changes and the Iran war sending gas prices spiralling.
Together, these trends mean the IEA expects US investment in fossil-fuelled power plants to overtake China’s in 2026.
The IEA’s latest world energy investment report shows that spending on renewables and electricity grids continues to dominate at the global scale.
In the US, Trump administration policies such as the phase-out of tax credits for renewables has led to the IEA revising its forecast for new wind and solar power downwards.
At the same time, US electricity demand is expected to rise by an average of 2% per year from 2026 to 2030, with data centres contributing half of the overall increase.
This is leading to what the IEA calls an “AI-driven push” to build new gas-power plants in the US, the world’s largest data-centre market and largest gas producer.
Globally, orders for new gas-power plants increased to 130 gigawatts (GW) in 2025 – a 25-year high – and US demand was a “major factor” in this, according to the IEA.
Much of the demand is coming from tech companies in the US seeking to bypass grid connection queues by building “captive” gas-power plants.
As the chart below shows, since the start of 2025 these US captive data centres alone have signed off on more investment in new gas turbines than any country in the world – aside from the US itself.
Overall, investment in grid upgrades, power equipment and electricity generation to support the buildout of data-centre infrastructure around the world hit $105bn in 2025, according to the IEA.
This is more than the total invested in the energy sector across the whole of Africa – a continent where more than 600 million people do not have access to electricity.
The IEA notes that strong demand for gas-power plants for data centres in the US – and, to a lesser extent, the Middle East – is “limiting the availability of turbines for near-term deployment elsewhere in the world”.
The agency also points out that as the tech sector becomes a “major energy investor”, accounting for around 40% of all corporate power-purchase agreements, it is also “underpinning momentum” for emerging clean technologies, such as small modular nuclear reactors and advanced geothermal.

The world’s most comprehensive disaster database – relied on by thousands of climate scientists and policymakers – is at risk of closing as a result of cuts to US foreign aid by the Trump administration.
The “emergency events” database (EM-DAT) has for 30 years provided free-to-use information on the size and impact of extreme weather events and other disasters around the world.
Its data underpins a vast range of scientific research, government policymaking, humanitarian response efforts and environmental investigations.
However, Trump’s dismantling of the federal Agency for International Development (USAid) – which provided 90% of the funding for EM-DAT – has left the future of the database in jeopardy, scientists tell Carbon Brief.
An open letter coordinated by climate scientists and signed by more than 4,000 academics and students is calling on governments, multilateral development banks and philanthropy to step in to stop the database from closing.
‘World’s memory of disasters’
For the past three decades, a small team of researchers at the Centre for Research on the Epidemiology of Disasters (CRED) at the University of Louvain in Belgium have maintained EM-DAT.
It is the world’s most comprehensive database of extreme weather events, such as heatwaves, floods and tropical storms, along with other disasters. It offers information such as the timing and length of an event, how many people were killed or displaced and the economic cost.
Since 1988, this continuous record has been free to use and independently verified by the researchers at CRED.
When considered in its entirety, the database provides more than just a list of disasters – it acts as a “memory” of how extreme weather events and their impacts on people are changing, says Prof Niko Speybroeck, an epidemiologist and director of EM-DAT. He tells Carbon Brief:
“EM-DAT can be considered the world’s memory of disasters. It contains more than 27,000 natural and technological disasters. It’s not just a database. It makes it possible to know who was affected, when, where and with what consequences.”
The database is frequently used by climate scientists. It is often cited in research papers and underpinned analysis in the most recent Intergovernmental Panel on Climate Change (IPCC) report on the impacts of climate change.
It is also used by government officials and environmental organisations.
The database is particularly important for global-south nations, which are less likely to have comprehensive national or regional records of disasters than those in the global north.
For example, the Indonesian government used EM-DAT to develop a national strategy against disasters, says Speybroeck.
The database has also been used to document the “disproportionate climate burden” borne by small-island nations, he adds, which “prompted the UN to release more funding” for these states.
EM-DAT is of critical importance to national and multinational initiatives tracking extreme weather in Africa, says Prof Dewald van Niekerk, head of the African Centre for Disaster Studies at North-West University in South Africa. Van Niekerk was one of the climate scientists who authored the open letter calling for EM-DAT to be protected from closure. He tells Carbon Brief:
“We use it on various levels, from sub-national straight up to continental level.”
Since 2018, van Niekerk has utilised EM-DAT to prepare reports on extreme weather events in Africa for the African Union. These efforts are to meet goals agreed under the Sendai Framework for Disaster Risk Reduction, a voluntary international agreement to prevent disasters from upending development.
Without EM-DAT, it would not be possible to conduct such analyses, he says:
“Not all [African] governments can compile these databases. Where they do, they are extremely fragmented. You can’t compare apples with apples.”
(Carbon Brief has also used EM-DAT data to investigate the impact of extreme weather on Africa, finding that such events killed at least 15,000 people on the continent in 2023.)
Uncertain future
Despite having a global impact, EM-DAT’s small team of researchers require just €300,000 ($350,000) a year to maintain operations.
For decades, EM-DAT obtained 90% of this funding from USAid, the US’s federal agency for foreign aid, says Speybroeck:
“[USAid] allowed us to work in an independent and neutral way, so we were not influenced by any politics. That was one of the strengths of the database. They only asked for us to leave it open access, meaning that anyone can use it.”
USAid was dismantled by Donald Trump after he became US president for the second time in January 2025. By July, the agency officially closed its doors.
Speybroeck received a letter in February 2025 informing him that his team were to lose their funding.
“I decided for a long time to keep silent,” he tells Carbon Brief. However, by the end of 2025, he chose to start speaking out about the impact of USAid cuts on EM-DAT.
Learning of the threats to the database, four leading climate scientists published an open letter in March calling for other governments, multilateral development banks and philanthropy to step in to stop the database from closing. It has attracted more than 4,000 signatures.
One of the letter authors, Prof Gabriele Messori, director of the Swedish Centre for Impacts of Climate Extremes at Uppsala University in Sweden, tells Carbon Brief:
“It’s very worrying that a long-term dataset that has become a reference for many different sectors, when looking at the impacts of a wide range of natural and technological events on society and the economy, could be suddenly interrupted.”
(The cuts to EM-DAT’s funding come as the Trump administration has laid off thousands of scientists and frozen research grants worth billions of dollars in the US. For more on how these actions are impacting climate science, see Carbon Brief’s explainer on how Trump is threatening polar research.)
Since going public about EM-DAT’s funding crisis, Speybroeck says he has had some “positive signals” from potential new funders, but “there is nothing on paper yet”.
Another letter author, Prof Dewald van Niekerk, says he hopes to see EM-DAT move towards a model of using multiple funding sources, to create a “more robust structure” where “no one can just pull the plug” on its work.

A new Trump administration rule will likely cost consumers more money while creating higher emissions of climate-warming superpollutants, industry and environmental groups warn.
President Donald Trump said new regulatory rollbacks on chemical refrigerants will reduce the prices consumers pay for groceries and will not impact the environment. However, U.S. chemical, refrigeration and air-conditioning manufacturers said the changes will raise prices and his administration’s own projections show that greenhouse gas pollution will increase.
