Many letters in The Echorecently have been very critical of the prime minister,and I heartily concur with those criticisms.
But they have not offered anything specific to do about climate change.
So it might be worth considering a couple of practical suggestions?
The first is to focus on electric cars powered by solar cells.
The problem with solar, as everyone knows, is the need to provide storage cells for when the sun doesn’t shine. But the beauty of electric cars is that they have the storage cells built-in.
If we could arrange things so that the cars were being charged continuously during the day – either by solar cells at home or at work – then running the cars at night would generally not be a problem.
We could largely eliminate petrol use by cars.
The second would be air-conditioning.
The beauty of air-conditioning is that we generally need it most when the sun is hottest.
If large flat-roofed buildings, like supermarkets, could be air-conditioned by solar panels on the roof, we could save a lot of electricity, and ditto with some homes. Air-conditioning is going to be ever-more important as the climate gets hotter, and indeed, a matter of life or death in some cases.
