The government has agreed a new funding arrangement with the controversial wood-burning Drax power station that it says will cut subsidies in half.
The power station, a converted coal plant in north Yorkshire, generates about 5% of the UK's electricity and has received billions of pounds from the government and bill-payers because wood pellets are classed as a source of renewable energy.
Though there are plans to eventually capture the carbon emitted from Drax, its emissions from burning the pellets are currently unabated.
Critics of the power station have called it one of the UK's leading emitters of the climate warming gas CO2, but Drax disputes that description.
