The cost of offshore wind power in the North Sea is 30% lower than that of new nuclear, writes Kieran Cooke - helped along by low oil and steel prices, reduced maintenance and mass production. By 2030 the sector is expected to supply 7% of Europe's electricity.
Belarus may have taken the brunt of the fallout from the Chernobyl nuclear disaster in Ukraine, writes Kieran Cooke. But now it's pushing ahead with its own nuclear power station at Ostrovets - just 50km from Lithuania's capital, Vilnius, where the project is causing widespread public concern.
Improved technology and falling costs are moving electric car sales into the fast lane as manufacturers seek achieve significant economies of scale, writes Kieran Cooke. And now China is leading the EV charge with its plans for 5 million plug-in vehicles by 2020.
Economist Nicholas Stern warns that the stakes have never been higher for radical action to be agreed at the Paris summit, writes Kieran Cooke: while we have the capacity to do all that's needed, it's far from clear that we will actually will.
China is by far the world's biggest producer of solar panels, writes Kieran Cooke. But the industry is suffering from over-capacity, razor thin profits and a failure to innovate.
China's success in driving down its fossil fuel burn will raise chances of a success at this year's Paris climate talks, writes Kieran Cooke - but first the world must appreciate the changes China is making, and how clean energy is catalysing a broader economic transformation.
Wind generates almost a twentieth of America's power, writes Kieran Cooke - and that's set to double in five years, despite the phase-out of tax credits. Now the main constraint to future expansion is power line capacity.
California's worst drought on record is far from over, writes Kieran Cooke. But while residents are getting used to dusty cars and parched lawns, the state's massive agricultural sector is still growing water-intensive crops like rice. How crazy is that?
Increased production from US fracking operations is a major reason for the drop in oil prices, writes Kieran Cooke. But there are warnings that the industry now faces an existential crisis from which it may never recover, as the financial sector faces the prospect of worthless shares and $100s of billions of defaulted debt.
Beijing has called a halt to new coal mines and will close hundreds of existing operations, writes Kieran Cooke. The move reflects the slowing economy, falling energy demand, concerns over air pollution and climate change, and the massive rollout of renewables.
Higher oil production and falling demand are creating big problems for the fossil fuel industry, writes Kieran Cooke. Risk-averse investors, spooked by drastic oil price falls, are turning away from the sector in search of more secure returns.
Despite record heat and drought Australia's emissions and coal exports are soaring, says a new report, and both are increasing as a matter of government policy. But a homegrown climate action movement is putting a spanner in the works - and just stopped its first coal train.
The growing popularity of olive oil has driven more intensive systems of olive tree cultivation, writes Kieran Cooke. But they are vulnerable to the kind of extreme weather that has brought pests and disease to olive crops across southern Europe, damaging crops and pushing up prices.
As the forest fires burn on in the western US, writes Kieran Cooke, a new report predicts that climate-led temperature rise will lead to millions more acres across the world being burned to the ground, especially in southern Europe and Australia.
At the UN climate summit in New York today, institutional investors managing $24 trillion of assets are demanding stronger, more ambitious policies on climate change, writes Kieran Cooke. These include an effective carbon price and an end to fossil fuel subsidies.
There are hopeful signs that China, the world's biggest emitter of greenhouse gases, is becoming less reliant on the polluting coal that powered its rapid economic rise, writes Kieran Cooke. Great news for China, and the planet - but worrying for coal exporters!
A new report names the 30 biggest sources of greenhouse gases in the EU, writes Kieran Cooke. Coal-fired power plants are undermining Europe's long-term targets on emissions reductions - and the UK and Germany lead the list of shame.
It's billed as 'the biggest story of our time', writes Kieran Cooke. This weekend viewers of Showtime, the US cable channel, will be watching the first of an 8-part documentary series on climate change: some of the biggest names in Hollywood are involved.
Australia has been growing rich from exporting coal to China. But as Kieran Cooke reports, China's renewable energy revolution may soon bring the 'good times' to an end.
