  •  FWIW, Ray Kurzweil says solar usage doubles (1+ / 0-)

    about every couple years and has for the last 20 years in a smooth curve. He's comparing it to Moore's law. Personally I think Kurzweil is a bit of a blue-sky optimist, but even if his claim is within the ball park and it holds true, in about 15 years, solar will be at 128% of where it is now and should handle our electrical needs. In part this is because solar becomes more efficient and cheaper every two years.

    Add to that successful advances in photo-voltaic films which could be used as coverings as we use fabrics, or even a photo-voltaic paint which is being demonstrated as usable, and solar may be ubiquitously used on clothing, cars, backpacks, or you name it. Every little bit adds up.

    And other researchers are figuring out how plants use photosynthesis which is much more effective and our current usage and are trying to adapt it to commercial usage. Battery storage is probably the bottleneck. Likely, that problem will continued to be resolved also.

    •  IMHO 20% from solar in 20 years (0+ / 0-)

      is optimistic enough. We dont have the manufacturing capacity and wouldn't for 5-7 years.
