Considering your following remarks I can only assume you are being facetious and/or sarcastic here.

I believe I was tactful and, more importantly, not insulting towards you in my reply.

Alot of assumptions there but thanks for being so "tactful" by not coming right out and calling me an ignorant brainwashed fool which your remark clearly implies I am.

Simply because I did not realise a single apparent law of thermodynamics does not mean I have been programmed by the oil companies to believe whatever they tell me.

Granted electric leaves no residues if the power source from which the electricity is produced leaves no residues. That will clearly not be the case in the foreseeable future.

At prohibitive cost for starters and for seconds, as has been mentioned previously, even if the car is covered in PV cells and a car port covered in PV cells were sold with the car it is very unlikely with today's combination of EV and PV cell technology that the car would be completely self sufficient. In the future that may change and is just one of the breakthroughs I would be waiting for before thinking of purchasing an EV.

Yes the power source must be the most natural possible. However, in todays world it will not be.

Well I'd be sceptical of those calculations. Further, since not every building is covered in them I fail to see how that would help power EV's sold today.

The other, fuel cell, is the more promising but it's really far away from the tangible goal of an autonomy of 300 miles. And their main propulsion is ... the electric motor...
The biggest trucks that we use in mines have electric motors.
The newest and most efficient propeller systems on huge ships are driven by electric motors.
Many trains use electric motors.

I never said EV's are no good or not useful or not in use today so I'm not really sure why you are listing all these uses of EV's.

Yes it is and that was exactly my point about whether or not swapping one form of emissions for another is of real benefit environmentally.

In todays world, EV's get their power from the power grid. The power grid produces the overwhelming majority of its electricity from unclean sources.

In the future maybe that will be different and maybe it wont.

Skip... well, it's not worse than petrol...

I never said hydrogen was perfect. I simply said I think I'll probably wait until it is an option unless something drastically changes with EV's.

I suppose the idea of a panacea is only good for binary people or those who insultingly and evengelically argue the merits of their preferred option over any other.
