The business secretary wants to triple the number of solar panels and double onshore wind farms by 2030.
Kwasi Kwarteng is putting forward the targets in an energy security white paper, due to be published by the Department for Business, Energy and Industrial Strategy.
The policy document has been delayed by several weeks while the Treasury wrangles over the cost implications. Kwarteng’s 2030 targets include increasing solar from its current capacity of 14 gigawatts to 50GW, offshore wind from 11GW to 50GW, onshore wind from 15GW to 30GW, and nuclear power from 7GW to 16GW.
