Re: Reduce is always the first element of the mantra...
-Reduce could mean restarting the government insulation programme
Which will be subcontracted to local private cowboy builders cold-calling pensioners, as these schemes always are.
-It can mean replacing old/failed gas boilers with heat pumps instead of new gas boilers.
Meet my concrete. Lots of it. Have fun digging through it and finding space for a heat pump. But don't worry, I won't be getting a new gas boiler as builders' regs would require new gas pipes and that would mean ripping out my fitted kitchen. Thankfully, the old one, unlike an iThing, is built to last decades.
-It can mean, as in the post above, choosing to walk to the local shop, or to school.
In rain, snow or 40 degrees. But many people cannot carry their shopping home in any weather and would rather not pay the 25% extra to buy from their local shop. Bus services are being reduced, albeit not by as much as the trains. And just wait for the 57 varieties of traffic reduction schemes to come on stream. Expect serious unhappiness as traffic gridlocks around closed roads and property values are hit.
Brexit has beggared the UK by about one third. 25% reduction in Sterling, the rest in extra border costs. Deglobalisation ends access to low-cost Chinese solar tech. Many Britons can no longer afford the basics, never mind the luxury of spending the extra to transition to green. That ship sailed with Brexit. The government are now having to fund a UK EV industry out of public funds. Ditto for silicon. And what else? The UK can no longer afford any of this. The UKG are hoping that private industry will innovate a magical fix (faery dust perhaps) that ensures we can have a net zero economy. But it won't, because it isn't possible.
We can, at best, shave a few percent off our impact. So we should be building solar farms, wind farms, desalination plants, and more reservoirs as fast as we can.
