24 Jun 2025

June marked an important moment for the UK as the government unveiled its latest Spending Review.

The UK has ambitious net-zero targets and a pressing need for energy security, so this month鈥檚 announcements were seriously important in terms of the green energy and the environment.

Here鈥檚 what happened鈥�

The Sizewell C nuclear reactor

The government has committed 拢14.2bn towards funding the new Sizewell C nuclear plant in Suffolk, the total cost of which could be up to 拢40 billion. They say it will take a decade to complete but nuclear projects never come in on time. Hinkley Point C was supposed to be switched on in 2017 but now it鈥檚 estimated to be 2031 鈥� a 14-year delay.

Sizewell C may eventually provide low-carbon electricity but the world has changed. It鈥檚 predicted to make seven per cent of the UK鈥檚 energy, but the same money spent on renewables would make 40 per cent of the energy we need 鈥� and those wind and sun parks could be up and running long before Sizewell C is ready.

Renewable energy is also cheaper. Hinkley Point C鈥檚 electricity will cost , almost twice the price of wind power.

This is our founder, Dale Vince鈥檚 verdict: 鈥淪izewell C is a waste of public money - 拢40 billion of it. Nukes are always late and over budget 鈥� and make the most expensive electricity we鈥檝e ever known. If we want to get our energy bills down 鈥� we have a faster, cheaper, cleaner option 鈥� power from the wind and the sun.鈥�

Nuclear, but different

The chancellor has also announced 拢2.5 billion for small modular nuclear reactors, with Rolls Royce to develop and build them.

The idea is that they will be easier and quicker to build than the likes of Hinkley Point C and Sizewell C, but they鈥檙e still not scheduled to be connected to the grid until the mid 2030s. That鈥檚 years after we hit the 2030 green energy target, something that鈥檚 entirely doable with today鈥檚 technology given the political will.

It begs the question: why do we need these expensive nuclear plants when renewables and batteries can solve our energy security problems long before they start generating power?

Climate Clock

The Climate Clock is a version of the Doomsday clock that has been running since 1947 - this tracks the risk of global man-made disaster, through man made technology (like nuclear weapons) - displaying the minutes and seconds left before midnight, when disaster strikes. The climate crisis is a small part of the calculations made.The climate clock uses a similar approach, but, focuses only on the climate crisis - which is the biggest and most urgent existential threat we face."The Climate Clock is a countdown to the biggest man-made disaster we face - but also a measure by which we can track our progress - moving from fossil to renewable energy. It shows we have no time to lose - the clock is ticking鈥�" Dale Vince, OBE.
