• Greens hit out at plans to 'reclassify' nuclear power (The Parliament, 2012-04-17).

• Ministers planning 'hidden subsidies' for nuclear power (The Guardian, 2012-04-20). Green campaigners are threatening to bring a legal challenge when the plans are made public later in the year. ... But the plans are likely to come under severe attack in the European parliament. The Guardian understands that the Greens in Europe are preparing to take legal action against the government, arguing that the plans amount to state aid for nuclear. Claude Turmes, a leading Green in the European parliament, told the Guardian: "We think these plans for feed-in tariffs for nuclear are state aid for nuclear power, which would not be allowed. We are looking at this very closely and we are going to fight this." The Decc official said: "We don't think it should be seen as state aid and are in discussion with the commission on that."

• Norstec. Harnessing the domestic renewable energy resources from Europe’s northern seas represents an extraordinary economic and investment opportunity. Over 40GW of offshore wind capacity could be deployed in the region by 2020, generating enough electricity to power London, Paris, Berlin, Dublin, Edinburgh, Copenhagen, Amsterdam, and Brussels combined. In the longer term, the total potential of economically-accessible offshore wind energy resources in Europe is larger than current European production of oil and gas put together.
