There are a surprising number of people on this thread who seem to be resiting any and all change and clinging to the large infrastructure.

Maybe it's because we have done the arithmetic and plugged in some real-world figures. And discovered that for the vast majority of people it simply does not compute either from a practical viewpoint or a cost viewpoint.

Come up with realistic figures for (a) how many MWh the average household with an electric car would need per year and (b) how many MWh the average roof full of PVs will generate in the UK (at its half-life point). Then give a realistic estimate of the cost of the installation and its expected lifetime.

Then see how realistic and cost-effective your "solution" is. And that's without taking into account the vast proportion of flat-dwellers who have no roof and/or cannot park their car close enough to charge from the home, or do not have a roof suitable for efficient PV installation.

It's similar to the notion that we should all grow our own vegetables. All great when you are hand-waving, but not so great when you go into the details of carrying it out.
