Question to the Department for Transport:

To ask Her Majesty's Government what source of energy (1) is, and (2) is planned to be, used to power electric (a) buses, and (b) cars; and what estimate they have made of the sustainability of those sources of energy.

The Department for Business, Energy & Industrial Strategy produce annual statistics and future projections of UK energy demand currently up to 2035. Of electricity generated in 2019, low carbon electricity’s share of generation amounted to 54.2 per cent. This comprised 36.9 per cent renewables and 17.4 per cent from nuclear generation. Fossil fuel’s share of generation was 43.4 per cent, of which 40.9 per cent was from gas, 2.1 per cent coal and 0.3 per cent oil. The remaining 2.4 per cent generation share came from pumped storage and other fuels including the non-renewable component of waste. It is not possible to identify accurately what proportion of energy is used to recharge electric buses and other electric vehicles.
