Take a look at what is possible. Not all of it is here yet, but you can help bring it along.

Solar power is a totally renewable source of energy

Bio-fuels are renewable, but they come with a cost

Wind power, wave power, tide power are all ways to use the forces of nature

Nuclear fission comes with a major cost

Methanol is a bio-fuel, but it takes energy to produce and takes food away

Hydrogen is only a way to transport energy from a source to a user

Hydrogen fusion is the longterm solution to an (virtually) inexhaustable supply

On the other side of the equation, you can help by conserving energy. If you do not use so much, there will be more to go around.

LEDs are a prime example of saving energy

Drive more slowly

Drive fewer miles

Move to more efficient devices
