The recent Committee on Climate Change Report shows how far and fast the UK needs to go to meet the threat of climate change. Its “Net-zero” ambition means completely decarbonising energy and electrifying more of our lives – it means we need to stop burning fossil fuels like coal and gas in the way we do now.
All the replacements need to be low carbon and much of that will be renewables. A large amount of renewables with reliable low carbon nuclear is a good mix to give the UK a secure and affordable electricity supply. Nuclear is a proven technology and it helps the electricity system deal better with periods with too much or too little wind or sun.
Countries like Sweden which have used this combination have decarbonised more effectively than countries which have complimented intermittent renewables with fossil fuels. EDF’s batteries are already playing their part in balancing an electricity grid with increasing amount of renewable power but their expense and size means they are not a solution for long term backup power.
For more new nuclear to be built, the government has been clear that costs must come down – and we agree. New nuclear costs are driven by construction and financing, both can be cheaper in a near-identical second station.
Hinkley Point C in Somerset shows the huge impact of nuclear projects on delivering training, skills and jobs in its region and every part of the UK. We can repeat that at Sizewell C. Climate change is an urgent problem and it is fortunate that the solution will be good news for people, the economy and our long term future on the planet.
