Britain's energy-per-capita has collapsed since 1965 [0]. How are they meant to build houses and live in them without energy? Construction is one of the most energy-intensive activities we have, and maintaining a warm home is up there. Britain is one of the usual suspects who listened to environmentalists, fought nuclear, let fossil fuels slide and bet big on renewables. They're going to need to have a bit of a focus…
The UK's targets meet the very minimum which they agreed to with other nations (Paris Accords: https://unfccc.int/process-and-meetings/the-paris-agreement) but are trotted out by the conservatives as if they're very forward thinking.
However, it was 2008 that the UK agreed that it would build more nuclear energy generation plants, and EDF planned to build 4 of those by 2017.
On 26 January 2017, the UK notified the European Atomic Energy Community (Euratom) of its intention to withdraw, following on from its decision to withdraw from the European Union. Leaving has wide-ranging implications for Britain's nuclear industry, including regulation and research, access to nuclear materials and impacts about twenty nuclear co-operation agreements with non-EU countries.
The UK withdrawal raises the question of nuclear fuel availability in the UK, and the need for the UK to enter into new treaties relating to the transportation of nuclear materials, which haven't even begun.
In 2020, nuclear power generated 46 terawatt hours (TWh) of UK electricity, just over 15% of gross electricity generation, and about half its 1998 peak of 91 TWh.
The new EDF sites aren't ready and are expected to be commissioned by 2026, just in time for Hartlepool and Heysham 1 to close down.
