Once this political objective was achieved the British government stopped worrying about energy. It has only re-appeared on the political agenda recently.
This is the sort of boring, infrastructure issue that the British political class, fixated by punching above their weight in foreign policy and eye-catching initiatives (for which read badly thought out and probably counterproductive, illiberal measures on topics like crime and immigration), only reluctantly engages with.
Building a new power station, whether coal-fired or nuclear is difficult. Most localities will resist such a scheme, which is why the idea seems to be to build on existing nuclear power sites.

Consequently a few dry winters leaves the reservoirs and ground water supply at a low level and there are hosepipe bans in southern England now, with a threat of drought orders (preventing certain uses of water in affected areas) and even the risk of the cutting of mains water supply in some places, if things go badly this year.
It is good that the free market is so much more efficient than the state. Think how bad things would be if the Labour Party still believed in socialism.

The difference between theory and practise in practise ...
