Liz Truss’s plans to stop farmers putting solar panels in their fields risks placing them under greater financial pressure, and fails to recognise the extent to which crops are now used for polluting biofuels, new research suggests.
Ms Truss reiterated her desire to crack down on solar power this week, saying she would stop farmers from “filling fields with paraphernalia like solar farms”.
But new research by think tank Green Alliance found biofuel production in the UK uses 77 times more arable land than farmland used for solar panels.
At the moment, 10 per cent of every litre of petrol put into vehicles in the UK is made up of biofuels – largely from plants such as oilseed rape, wheat and sugar.
While this portion of the fuel is routinely described as “sustainable”, studies have revealed that the difference is minimal, and in some cases “worse than fossil fuels”, with additional concerns that giving over large tracts of land to growing crops to burn in engines can result in the degradation of land and increases in food prices, as competition for land rises.
Biofuel production for use in the UK occupies around 108,000 hectares of land – the equivalent of 200,000 football pitches – enough space to grow food for around 3.5 million people per year, Green Alliance said.
By contrast, solar farms built since 2010 only account for around 1,400 hectares of arable land in the UK.
However, farmland used for solar panels can also be used to grow crops, with previous research suggesting that combining food production and solar panels results in just a 7 per cent reduction in yield on average.
Ms Truss’s comments come a week after she made a similar pledge at another rally, when she told the audience: “Our fields… shouldn’t be full of solar panels, and I will change the rules. I will change the rules to make sure we’re using our high-value agricultural land for farming.”
Rishi Sunak has also indicated similar opposition to solar panels being built on farmland.
Meanwhile, plant biomass production uses nearly three-quarters as much land as the entire UK potato industry and is a “strong factor” in rising food prices, analysis has found.
Boris Johnson recently clashed with Joe Biden after the PM said he wanted to slash production of biofuels in a bid to free up land for food production, saying the process is pushing up the cost of food.
The Liberal Democrats’ spokesperson for the environment, Tim Farron told The Independent, Ms Truss’s stance could put farmers out of business.
He said: “Liz Truss is promising yet more pain for farmers, not only did she personally agree trade deals that undermine our high standards, but now she’s saying that they can’t diversify their businesses by supporting green energy.
“We need our farmers to protect our countryside, repair our natural environment and help us cut emissions, all while growing our food. Liberal Democrats back British farmers to do that, meanwhile, the Tories threaten to drive them out of business.”
Ms Truss’s contempt for renewable energy also appears to be out of step with what Conservative voters would like to see, polls have shown. Not least due to rising concerns about the energy crisis, the environment, and the need to end dependency on gas.
Friends of the Earth’s head of policy, Mike Childs told The Independent that Ms Truss’s stance was “bizarre”.
He said: “With millions more people about to be plunged into fuel poverty it’s bizarre to suggest that we should stop building solar farms, which will provide the nation with cheap electricity, as well as cutting climate-changing emissions.
“Solar farms can happily co-exist with sheep farming, and be a haven for wildflowers, bees and butterflies.
