Greenpeace UK director John Sauven said:
Hinkley C fails every test - economic, consumer, and environmental.
It will lock a generation of consumers into higher energy bills via a strike price that's nearly double the current price of electricity, and it will distort energy policy by displacing newer, cleaner, technologies that are dropping dramatically in price.
With companies like Dong Energy now saying the price of offshore wind will drop so much it will be on par with nuclear by the 2020s, there is little rationale for allowing Hinkley C to proceed.
Giving it the green light when there is no credible plan for dealing with the waste is also unacceptable. David Cameron has said himself that, until the waste issue is sorted, no new investment is possible.
This is yet another Government U-turn which is creating uncertainty for investment in both energy efficiency and renewable energy, which, despite recent headlines, remain the best long-term solution for the consumer, energy security and tackling climate change.
