disingenuous, though, isn't it? And the capex you blithely mention for solar ignores the fact that PV technology is hugely expensive in terms of outlay and that the payback simply isn't big enough or fast enough to make it an attractive, large-scale option - certainly in this country. Geothermal tech on any large scale would mean essentially digging up most of the country at enormous financial and environmental expense, while wind farms are hugely unreliable (the gearbox bearings being a massive issue for geared ones and the high cost and shortage of rare earth metals being a problem for those using permanent magnet technology). Equally, their maintenance is incredibly difficult and expensive - especially offshore. And then there is the simply enormous and incredibly costly infrastructural issue of actually getting the energy these sources generate into the f**king grid.

And as for everything 'going electric', well a/ no it isn't and b/ where do you think the electricity is coming from?

And, as an engineering and technology journalist, I know a fair bit about driverless vehicle technology. It is certainly coming, but has no relevance in terms of environmental impact.
