Boris Johnson’s speech was light on policy but heavy on vision - although it was not a particularly novel vision, and the passages about private enterprise being the foundation for prosperity were very similar to the speeches he’s been making at Conservative conferences for years.

One of the most interesting passages, though, came when he spoke about his desire to use the coronavirus crisis as a catalyst for change. In doing so, I have identified Churchill’s wartime coalition government as a model. He said:

In the depths of the second world war, when just about everything had gone wrong, the government sketched out a vision of the post-war new Jerusalem that they wanted to build, and that is what we're doing now, in the teeth of this pandemic.

He also said that crises like this one were “a time to learn and improve on the time that went before”.

(But at this point in his speech Johnson did not find time apologize to the Labor MP Kate Green. For the last two weeks at PMQs he has criticized her for saying, in relation to Covid, that you should never let a good crisis go to waste, but her argument was very similar to the one he was making today.)

Boris Johnson to unveil plan to power all UK homes with wind by 2030.

PM vows to make Britain world leader in low-cost clean power with ‘Build Back Greener’ drive.

Boris Johnson will promise to power every home in the UK with offshore wind energy within a decade, pledging to make the coronavirus pandemic a catalyst for green growth.

In a speech to the virtual Conservative party conference on Tuesday, he will say that the government will invest in a clean energy future to create “hundreds of thousands, if not millions of jobs” in the next decade.

The prime minister said the UK would “become the world leader in low-cost clean power generation – cheaper than coal and gas”, comparing the UK’s resources in offshore wind to Saudi Arabia’s oil wealth.

“We believe that in 10 years’ time offshore wind will be powering every home in the country, with our target rising from 30 gigawatts to 40 gigawatts,” he will say. “Your kettle, your washing machine, your cooker, your heating, your plug-in electric vehicle – the whole lot of them will get their juice cleanly and without guilt from the breezes that blow around these islands.”
