Article here about a Renewable Energy European supergrid in place by 2030.
High voltage Direct Current enables electricity to be transmitted long distance without the losses that we get with the present AC grid. The idea is that a vast europe-wide grid will smooth out the intermittency of wind and solar sources.
The cost is trivial by Credit Crunch standards - a mere 1.4 trillion euros over 20 years, which is only a fraction of the investment planned for planet - killing fossil fuels over the same period.
So it is all very possible, very economic, very realistic. All we have to do is to get the decision makers (Prime Ministers, Ministers, Civil Servants &c) to
(a) understand it,
(b) stop letting the coal, gas and nuclear barons pay for their lunches.
(a) is not difficult.
(b) is going to be immensely difficult.
In fact it is going to be so difficult that I now see, on reflection, that the HVDC grid idea is just another utopian, hopelessly unrealistic green dream that is never going to get anywhere, so we all might as well shut up go home and accept the fact that we are all just going to have to die.
Damn. It was such a lovely planet. Pity about the electoral system...
