Solving The World Problems

[Fake Messiah]

Fortunately, there's already a solution to hand - solar.  I mean, the sun is everywhere.  The cost of building and maintaining solar power systems is dropping like a paralyzed falcon, storage systems are improving and conservative estimates are expecting solar power to provide some 30% of the world's electricity needs by 2050 (I think that's what I read).

Plus, if your solar panel breaks, you can clear it up with a broom - no HazMat suit required.

Sorry I forgot to address this. You can't be serious? While solar is good help, it is not suitable as a primary central-station power source. Fifty years from now, only coal, fission, and fusion are capable of supplying the dependable, steady backbone power that the civilized world can count on.
1GW of electricity needs 50 square miles or to completely supplement all today's energy needs you would need area of United States all covered with solar panels.
The atmosphere absorbs part of the sunlight. The sun does not shine at night and does not rise high in the winter. There are cloudy and stormy days. There is little sunlight at high latitudes, where the power is most needed. Solar cells can capture only part of the solar spectrum and are not efficient at that. The peak efficiencies quoted apply only when the sun is directly overhead. The color of sunlight changes near sunset and no longer matches the color the solar cells are optimized for. Solar panels cannot economically be turned to follow the sun as it moves across the sky. We are lucky to capture a few percent of solar energy, but even that is a lot of energy that should not be wasted.

But sure there are solutions even today like Earthship - a house you can live in that you don't have to slave to pay the heating bills, cooling, electricity and even food is free if you are a vegetarian.
