I was watching Glenn Beck tonight and he interviewed a guy named "Raymond Kurzweil". This guy is some kind of genius inventor and idea man who is also somewhat of a futurist.
He is big into technology and he explained how technology is growing exponentially and how that will lead to the rise of solar power as our number one source of energy for the planet. I have always thought this was our true source of energy and have wondered why we have not reached that point in our technology yet.
This guy says that in seven years we will have reached that point and by building massive solar plants in the desert we will be able to generate enough electricity to power the country. He also stated that the sun provides us with 10,000 times more energy than we need to consume worldwide....
Here is a link if you want to read more about him. He has been inventing stuff for years.
