Find efficient heating options that reduce your carbon footprint:
UK Fuel Mix disclosure information, published by Government Department DESNZ, recognises electricity from wind, solar and nuclear fuel produces zero carbon dioxide emissions at the point of generation.
The zero-carbon electricity purchased is supplied to the National Grid. Customers receive electricity via the National Grid, not directly from zero-carbon generators.
The below table summarises zero-carbon generation by company demonstrating EDF generating 19.8%. The data supporting the table below and the % values is sourced from a mixture of industry settlement data and the UK government renewable obligation database.
|Company||Onshore wind / offshore wind / solar / biomass / hydro TWh 2022||% of total zero carbon generation|
Sources: UK figures from company reports; EDF analysis; total zero carbon generation for 2022 from DESNZ Energy Trends 5.1
Note: SSE figure is for financial year 2022/23. All EDF generation in UK is currently located in GB.
Three and a half times more efficient is based on a heat pump efficiency of 3.48 vs a gas boiler of 93% or 0.93. 3.5 x 0.93 = 3.25, which is less than 3.48.
