In 2010 or 2011 solar capacity was increased by 10GW in one year. We are currently at about 70GW, so it would take 7 years at the 2010 rate - one would assume that with much more efficient panels available today, the first doubling could be easily done in 5 years and obviously we might try much harder today than we did back then, when it was not critical yet. I wouldn't see why we couldn't do 20 GW/year today and more in the future. Going to renewables certainly is a 90/10 style problem, but as we are very much pressed for time, we should push for the 90 quickly first and then tackle the rest. And if we hit 20GW/year solar buildup and also have strong wind buildups, we might quickly have enough to just use power2gas and the existing infrastructure to bridge the gaps in the supply. And of course, some amount of importing is acceptable too. If Arabia and northern Africa build up large hydrogen plants, we should buy that too. Helps achieving our goals quicker, gives those regions important income. But of course, we shouldn't make us so much dependant on a single suppler any more as we did with gas. What other ways would we have to achieve this goal in short notice?
