There are local government proposals to redevelop the area where I live based on a garden city plan
Amongst other things such as better railway access and a metro tram extension to cover our area, housing will be fitted with solar panels and electric vehicle charging points.
We already have solar panels at home which significantly reduce electricity costs.
Maybe the cheap solar energy coupled with domestic wind turbines would make EVs virtually cost free to run?
Only during the daylight hours, provided you are generating more than you use. But as most EV cars will have been used for the commute they wouldn't be at home.
Local area wind turbines are an effective way forward, provided nimbys don't block them.
A solar panel set up of 4Kw as opposed to the 2.7Kw usually put on housing by local authorities will generate sufficient electricity to run a house in concert with the usage change to make it effective. If refurbishing housing stock replacing white goods and ovens/hobs with A+++ rated appliances and LED lights will deliver considerable benefits. The biggest user of energy in a home is the washing machine, followed by a dishwasher. Only run them whilst generating and not at the same time realises the benefits. It's the mindset change required to not fill the dishwasher after dinner and not switch it on till the following daytime, then the washing machine. But it pays dividends. Our solar panels generate 3 times more electricity than we use. Probably a better investment than a pension fund currently.
The main issue with EV is the grid capacity. The electrification of more railways, more trains, HS2, trams, onshoring manufacturing, EV charging etc al has to be accounted for. Sadly our political idiots haven't figured that bit, the additional capacity required, as yet. Base load can be easily met, it's the mid winters severe storm that is the issue and the massive uplift in peak load requiring capability that is the crux. Solar can't be switched on in the middle of the night. Wind cannot be switched on in Scotland, and has to be switched off in high winds. Deep water offshore wind is capable, when the infrastructure is there, but that is still a way off.
Other difficult decisions like replacing poorly insulated and energy wasting housing stock with new energy neutral using things like local area ground source heating networks, small nuclear generation are probably beyond the wit of the populous currently. It needs open and frank debate. Too many vested interests at present, particularly developers who are solely focussed on short term returns.That is the problem with having an economy based on the price of houses, primarily in the South East, instead of goods and services saleable at scale across the globe.
