Recommendation 36

Decarbonising electricity generation is crucial to the government’s net zero strategy, including decarbonising home heating. If, as the government expects, most homes switch their heating systems to heat pumps or heat networks, it is important that these are powered by clean sources of electricity to achieve decarbonisation. In 2021, the government set an ambition that by 2035 all electricity should be generated using clean sources, subject to security of supply, while meeting an expected increase in electricity demand of up to 60%. This means phasing out polluting types of electricity generation, such as gas-fired power stations and replacing them with a new mix of zero and low-carbon generation, including wind, solar and nuclear power.73
