And the profits grow

[Zenda]

For those who think the sun cannot sustain the earth...

http://en.wikipedia.org/wiki/Photovoltaic_array:

"The unpopulated area of the Sahara desert is over 9 million km², which if covered with solar panels would provide 630 terawatts total power. The Earth's current energy consumption rate is around 13.5 TW at any given moment (including oil, gas, coal, nuclear, and hydroelectric)."

That's based on current technology, with 12% efficient solar panels.


For those who think that nuclear power is the answer to all problems...

http://en.wikipedia.org/wiki/Uranium:

"The ultimate supply of uranium is believed to be very large and sufficient for at least the next 85 years"

That's right. Only 85 years, according to optimistic sources (like http://www.iaea.org/NewsCenter/News/2006/u...resources.html). Hardly worth investing in, I'd say, considering all the risks.

http://en.wikipedia.org/wiki/Uranium:

"In other words, there is very little high grade ore and proportionately much more low grade ore."

In other words, it won't be long before nuclear power becomes expensive too.
