I'm guessing that the most underdeveloped source of energy is created by the oceans' tides.

Lets face it, the reason alternatives haven't been developed is that the profits are not as good as they are with oil production. I can think of at least one oil-rich family that has probably done all they can to insure that their revenue is not hurt by alternate sources of energy.

...but no matter what alternate sources are developed, it must be coupled with an effort by individuals to curb consumption. As the biggest consumers, N. America must lead the way - otherwise we have no right to deny developing countries the right to squander and pollute.
