The National Infrastructure Commission is calling for a halt to nuclear construction plans and a ramping up of renewable energy schemes.
Its National Infrastructure Assessment report wants to see 50% of electricity generated from renewable sources like wind and solar by 2030 – up from 30% today.
The report said: “The National Infrastructure Assessment therefore cautions against a rush to agree government support for multiple new nuclear power stations, and proposes that after Hinkley Point C in Somerset the Government should agree support for only one more nuclear plant before 2025.
“This would give flexibility to move towards newer low-carbon energy sources in future, while at the same time maintaining the UK’s nuclear supply chain and skills base.”
It is also calling for a major upgrade in the energy efficiency of Britain’s buildings and £3.8bn to be invested between now and 2030 to make improvements to the country’s social housing stock.
Preparing for the growth in use of electric cars is also a key theme of the report.
It calls for widespread investment in car charging infrastructure to ensure “that charging an electric vehicle is as easy as refilling a conventional vehicle, or even easier.”
Chairman of the National Infrastructure Commission Sir John Armitt said: “If we act now we have a golden opportunity to make our country greener, and protect the money in the pockets of consumers long into the future – something few of us expected to be able to do.
“Ministers can seize this chance by investing in renewables and other low-carbon technologies so they become the main players in our energy system – something that was considered a pipedream as little as a decade ago.
“But they need to act now to realise the full potential of what can be achieved.”
