The first step to help you cut heat loss is to get insulation professionally installed. A typical house with no insulation will lose 33% of heat through walls and 25% through the roof(1)
UK Fuel Mix disclosure information, published by Government Department BEIS, 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 32.4%. 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.
|ZERO-CARBON GENERATION SUMMARY BY COMPANY||2020||2020|
|Supplier name||zero-carbon||GWh of zero-carbon electricity generation||% of overall zero-carbon electricity generation|
|Fred Olsen Renewables||zero-carbon||1,100||0.9%|
These estimated annual savings come from the Energy Savings Trust website. They’re based on an average three-bedroom semi-detached home. If you’d like to find out more, go to energysavingtrust.org.uk.
Calculation is based on:
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.
