Gravitational energy stored in the planets.
If one considers how planets interact, they have forces that pull them towards the sun. The formula for this is:

The numbers are awful to look at, but solve quite easily.For the Sun and Jupiter,
They pull together with a force of 4.16E+23 Newtons

The numbers are awful to look at, but solve quite easily.For the Sun and Jupiter,
- G is approximately equal to 6.67 × 10−11 N m2 kg-2
- The mass of Jupiter is 1.90E+27 kg.
- The mass of the sun is 1.989E+30 kg.
- the distance from the Sun to Jupiter is 7.79E+11 meters
They pull together with a force of 4.16E+23 Newtons
So what?
Well, the world's energy utilization is 4.62E+17 BTU per year. ref. This is 4.87E+20 Joules.
Still so what?
Bottom line - if we could somehow harvest the gravitational energy between the Sun and, say, Jupiter, by "stealing" energy from its orbit about the sun, the World could steal all the energy it needs from the orbit of Jupiter about the Sun - causing it to move slowly towards the Sun at a rate of ONE MILLIMETER A YEAR. Or the thickess of a dime.
There is so much energy stored in the orbital character of this one planet alone, it would take a million years of energy harvesting from Jupiter to cause its orbit to diminish JUST ONE KILOMETER from 778,547,200 kilometers to 778,547,199 kilometers. There's that much energy. It would take 600 billion years for Jupiter to decrease its distance to the Sun by 0.1%

It's out there.
All we need to do is figure it out.

PS: Check the math.
PPS: I ignored the effect on kinetic energy. If you're so smart, figure the exact answer out yourself.
PPPS: If we stole the energy from the Moon's orbit about the Earth, it would move the moon about 2.5 meters/year closer to the Earth. After a million years, the Moon would be 1% closer to the Earth than it is now. (If that freaques you out, the Moon is already wandering further away from the Earth from tidal effects, about 4 cm/yr.)
Enuffathat.
Are there any other mega-sources for energy that you know of? It's out there - we just gotta figure out how to get it. (And make sure that Cheney doesn't get his mitts on it.)
