I should have posted this a while ago but it maybe part of the reason why fuel cells went crazy a little while ago. Basically the IEA says that countries converting to a renewable based power system would be fairly cheap and that all base load power sources should be able to compliment renewable systems. Intro paragraph of a story on the report below and link


"The International Energy Agency (IEA) has released a report in which it concludes that the integration of large amounts of renewable energy can be achieved by any country at only a small increase on whole system costs, compared with the current fossil-fuel heavy electricity systems. Making the conclusion even more startling is that the IEA used present-day costs for solar PV and wind, with the two most widely-deployed renewable energy technologies set to provide the bulk of the generating capacity in these transformed electricity systems."
