A green think tank has criticised Rishi Sunak’s promise to protect farmland from solar farms, saying biofuels use 77 times the amount of arable land.
Dustin Benton, policy director at the think tank, said: “Solar energy isn’t standing in the way of food production in the UK.
“Instead, solar panels generate cheap, clean energy that doesn’t depend on Russia, and provide income to farmers too.
“A much better way of feeding people would be to stop using food crops to fuel cars. Biofuels for cars are a zombie policy.
“It’s now cheaper to decarbonise transport by getting more electric vehicles on the roads and freeing up land we’ve used for biofuels for food production instead.”
The Green Alliance said biofuel production covered 108,000 hectares of arable land, enough to grow food for 3.5 million people, while solar farms covered only 1,400 hectares.
The think tank added that land used for solar farms could be used to grow crops at the same time.
The former chancellor also promised to boost domestic food production through a UK food security target.
His rival Ms Truss has previously described solar farms as “paraphernalia”, as she emphasised the importance of using productive arable land for growing crops.
