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

To ask the Secretary of State for Energy and Climate Change, what estimate she has made of the proportion of electricity that will be produced from renewable sources in (a) 2020, (b) 2030 and (c) 2040.

DECC has published projections of electricity generated by renewables up to 2035 as part of the 2015 Updated Energy and Emissions Projection, as follows:

Source: Annex J of the 2015 Updated Energy and Emissions Projections, available at https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/477618/Annex-j-total-electricity-gen-by-source.xls. Note that these figures include a small amount of electricity generation from non-renewable wastes.

Projections of the electricity mix so far into the future are subject to considerable uncertainty as they depend on uncertain factors such as the degree of cost reduction, fossil fuel prices and future government policy.
