We could recycle the world's most "efficient" solar cells when they fail, um, couldn't we?

20. Keep it simple

For us poor beknighted unintelligent souls who don't care about anything except feeling good about ourselves.

1) how many of the world's 570 exojoules are attributed to electricity demand annually?
2) out of that portion attributable to electricity, how many new exojoules have been added in the last 10 years (when almost all of the investment in solar has taken place)?
3) how much of the new growth in electricity growth in the last 10 years has been attributed to the BRIC and other developing countries?
4) how much of this new growth has been supplied by renewables, coal, gas, and nuclear, and what has been the investment in each?
5) given the desperate energy poverty in the developing world, which technology is best suited to provide basic needs - solar, wind and storage - whose costs are rapidly dropping and which can provide power close to where people live and which don't require expensive transmission lines, or expensive nukes which adhere to an outdated centralized generation model?
