Here we go again...

Yeah, like electric trains... problem is that electricity is generated with CO2 emissions.

Alexei, pardon me for saying so, but that is the standard but dim response of rabid greenies.

Electricity is a highly transferable energy source, so if all your new transport is electrically-powered, it can use electricity from anywhere - wind farms, nuclear, hydro - when it becomes available.

I heard a greenie a few days ago on the radio saying that nuclear power stations will not be much use because most of our homes are heated by gas. I'll leave you to work out the lack of foresight that went into that remark.

Main issue is burning of fossil fuels.
Everyone in the world knows these are of a FINITE supply and will start to run out in the next few decades (a blink of an eye in global timescales).
Other means of transportation and energy generation are essentially Carbon neutral.
Therefore we will soon (in global terms) be in a position of using far more CO2 then we are producing and the world climate will adjust accordingly. So whether we use it now or eke it out for an extra 20 years makes no difference.

Excellent point. On the one hand we have worriers about exponential use of fossil fuels, on the other we have worriers about fossil fuels running out.

Unfortunately its not that easy - say take National Grid, nicely allowing to transfer electricity around... can't be bad, right? Well, electricity does not get moved over wires for free - you do lose some of it and I heard on the radio that about 66% of electicity is actually lost in national grid, that's pretty hefty loss.
