The latter is concentrating minds as costs spiral and households struggle to pay to keep themselves warm and fed.

With an over reliance on imports and renewables, we must find a way, and as quick as we can, to keep UK plc on the move.

And let’s not forget that we contribute one per cent of global emissions, compared to China, the US and India, with figures of 28, 15 and 7 per cent, respectively.

We’re also world leaders in reducing them, though few acknowledge that.

The electric car revolution is stalling, with costs, lack of recharging points, inadequate domestic supply, battery problems, ‘range anxiety’ and this week the possibility of road tolls, slowing uptake.

And the Prime Minister is backing a series of new, British-built, mini nuclear reactors.

Decarbonise we must, but not to the serious detriment of our country.
