I Was Just Watching Carbon Nationand i like how they outlined it:
Human civilization requires 16 terawatts a year to function. We all want and need to get these 16 tw from clean, renewable energy sources; however, we only get less than two terawatts from renewable energy sources.
But think of it this way. 86,000 terawatts hit the earth every day as solar power. We can get over 32 terawatts from geothermal power. And over 870 terawatts of wind power are blowing around the globe right now. We only need 16.
Watch Carbon Nation on netflix, or watch it at
or just google the title and im sure you can watch it free somewhere.
