End support for Drax: stop subsidies for biomass power and phase out coal!

The Undersigned

22nd April 2015

Hundreds of millions of pounds meant to be spent on green energy will soon be lavished on Britain's biggest coal fired power station to reward it for burning 7 million tonnes of wood pellets a year - meant to be 'renewable' but actually driving biodiversity loss and even worse for climate change than coal. DECC must stop this madness! more...

The mirage of fossil fuel wealth - our energy future is green, renewable, decentralised

Vicente López-Ibor Mayor

20th April 2015

Hopes of strengthening Britain’s energy security are often pinned on the fossil fuel industry says Vicente López-Ibor Mayor, as exemplified by the hysteria over the claimed 'discovery' of 100 billion barrels of oil beneath Gatwick airport. But the real long-term solution lies with abundant and ever cheaper decentralised renewables. more...

Why a submerged island is the perfect spot for the world's biggest wind farm

Xavier Lemaire

27th March 2015

Way out in the turbulent North Sea, the Dogger Bank may seem like an unlikely place to site a large part of Britain's energy infrastructure. But given the stable sea floor, consistent winds, and distance from sensitive neighbours, it could be the perfect place. Even the fish could come to like it! more...

Energy market madness is the death spasm of the oil age - renewables now!

Nafeez Ahmed

4th February 2015

Current oil price volatility is a symptom of the end of cheap oil, writes Nafeez Ahmed, and it's destablising the entire global economy. The answer is a major shift to renewables - but the the International Energy Agency, which should be leading the transition, is in the grip of nuclear and fossil fuel interests. Instead the leadership must come from us, the people! more...
