Food for thought

• 3.9×10²²J : estimated energy contained in the world's fossil fuel reserves as of 2010
• 2.2×10²³J :total global uranium-238 resources (using fast reactor technology)
• 3.8×10²⁶J : total energy output of the Sun each second

Every single second, the sun outputs more than a thousand times the sum of all of the fossil fuel and nuclear fusion fuel we believe exist on the Earth

What I find even more interesting:

• 5.5×10²⁴ J : total energy from the Sun that strikes the face of the Earth each year

One order of magnitude higher than the total uranium figure, two higher than the total fossil fuel figure. I'm not saying we could harvest all of that energy, but even a fraction of it would be enough.

(Actually... 1/10000th would be enough, given this: 5x10²⁰ J : total world annual energy consumption in 2010 )
