Did not mean to be insulting, in fact, wasn't. First I am not arguing for an all wind and PV grid, as i've stated over and over.

But to have wind a very high penetration in the grid, i also stated is now  EASY to do FAST in a mature industry, which wind has already proven. I stated the UK could ramp up to 6 gigs a year within 3 years, that's huge. Wind's current capacity total in the UK is 6.5 gigs, equal to 4.5% of annual demand. So i claim 4.5% of new demand met each year by 2015.

Further, it could be even higher, AND it all begins with using already existing under capacity "shovel-ready."

Yes coal must go away fast, and fossils as well. But it's a huge step forward to just use them as old-style base load, and some others for spinning reserve or cold start reserve.

As for Hitachi saving us from coal, that's another discussion. Of course i understand that introducing new technology in our civilization is problem free, with the very first plants working flawlessly over their lifetime, but i can't seem to name another technology of such a scale which hasn't had any number of whoops.

including wind, with regular whoops.... though our whoops ain't all that bad.

Airbus wing cracks anyone?

Fazit: a renewable powered grid is completely feasible, and the 15 year aggressive time frame is more than long enough to make the proper changes.

Yes, and doing it actually comes with real jobs. And the power comes from the energy source that gave us life, which could have some additional benefits for a sick civilization. Without the Hubris of thinking your civilization is capable of building miniature suns yet.

And i mentioned Romania to show that a far less industrialized area has already done it, so perhaps the UK might also be capable of following Romania's lead.
