Is Hinkley Point C the future of low carbon electricity MWh strike price to incentivise the development of generation in Britain or a white elephant – a Hinckley C was based on the assumption that the technology hangover from the 20th century? The new price of non-nuclear fuel would double. Yet they are UK government seems to be having doubts. It states lower than in 2013 not rapidly rising.

The Esos savings identifi ed though they are from a technological point of view, they are not the end of the whole story but if we just take should not be built.
