Friends of the Earth director of policy and campaigns Craig Bennett said the nuclear power agreement with Chinese investors was "a bad deal for taxpayers".
Mr Bennett said:
The Government has chosen to give enormous long-term handouts to Chinese and French companies when they could be developing a world-class renewable industry in the UK.
The reality is that nuclear power takes decades to build, but climate change and energy challenges are upon us now - this focus on nuclear distracts from more urgent priorities such as delivering energy efficiency to households who are suffering rocketing energy bills due to the rising price of gas.
The head of policy at environmental group Friends of the Earth, Mike Childs, has said that experts expect to see extreme weather events such as intense rainfall become more common as a result of global warming:
So far, the world has warmed by an average 0.7°C above pre-industrial levels - if temperatures rise by the 4°C scientists widely predict then we can only begin to imagine the impacts on our lives and livelihoods.
But there is still time to tackle climate change. We must end our dependency on dirty fossil fuels and reap the benefits of energy efficiency and developing clean power from the wind, waves and sun.
