As for the electricity supply issue, I would think that many motorways are ideal places for wind turbines as motorways already blight the countryside. They could be placed alongside electricity pylons in many places.
I would also like to ban the word goals from the COP26 talks. It is not goals that we need (we have had these for years) but actions, rather like the budget where a proposal is made alongside the likely cost or benefit to the exchequer. This would be transparent and measurable. For instance, building new roads would increase CO2 by x tonnes, electrifying a railway line would decrease emissions by x tonnes. Planning permission for onshore wind turbines would reduce emissions by x tonnes.
In 2019, 27% of net greenhouse gas emissions in the UK were estimated to be from the transport sector, 21% from energy supply, 17% from business, 15% from the residential sector and 10% from agriculture. Each sector needs addressing. Targets rather than goals with pre-proscribed penalties for failure to reach them.
Agriculture could start by moving to electric tractors (already produced by John Deere), farms have the space and resources to produce their own electricity by wind, solar, biofuels. Food supply chains need addressing globally and locally – and we definitely do not need trade deals with Australia and New Zealand for food stuffs we can produce here.
And before people complain that this is so middle class, and what about the cost of food for the poor I would reply that it is about time we ensured a decent living wage for all. No full time worker should need to claim universal credit, wages should be sufficiently high, and rents capped to sustainable levels. And if a landlord loses out – that is a gamble they took by buying a property to rent in the first place, it may be necessary to have a compensation scheme in place until the system readjusts.
