Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what recent estimate he has made of the proportion of UK electricity demand which will be supplied by non-nuclear renewable sources in (a) 2020, (b) 2030 and (c) 2040.

The Department’s Energy and Emissions Projections[1] include estimates of total electricity generation by source to 2035. The latest published projections show (non-nuclear) renewable sources accounting for around 40% of total generation in 2020 and over 50% of total generation in 2030. The projections do not extend to 2040, but it is anticipated that the equivalent proportion for 2040 would be over 50%.
