Go here and do the math yourself: solar-estimate.org I could install a system for $137,000 that would supply nearly 50% of my power. Wow - that's fantastic!

"How many square meters are AT the equator, you moron!" Zero....moron. I thought you were an engineer.

Bentway, > The amount of solar energy hitting the Earth in one hour Unless you are advocating covering the entire Earth with solar panels, such a statement is meaningless. > Where do you GET these crap "facts"? Your own link said so: "By the time it reaches Earth's surface, the energy in sunlight has fallen to about 1,000 watts per square meter at noon on a cloudless day." Tenchusatsu

The amount of solar energy hitting the Earth in one hour, if we could perfectly capture it, would power us for a YEAR! Which allows a LOT of inefficiency. We also wouldn't be able to see anything on moonless nights without artificial lighting, having captured all the natural sunlight. That's a pretty big if. Why stop at all the energy of the sun hitting the Earth, why not if we could capture the sun's entire output, which is about as likely for the near term future. The inefficiency applies to the extremely tiny portion of the sunlight hitting the actual solar power cells or mirrors reflecting on to solar thermal generators. How many square meters are AT the equator And what percentage of those will ever be covered by solar cells?
