Plenty of helium on the moon.

Lunar Mining of Helium-3

There is no doubt that one of the most difficult problems that a peaceful world will face in the 21st century will be to secure an adequate, safe, clean, and economical source of energy. Existence of lunar helium-3, to be used as fuel for fusion reactors, is well documented; verified from numerous Apollo and Luna mission samples, current analyses indicate that there are at least 1 million tonnes embedded in the lunar surface. The helium-3 would be used as fuel for fusion reactors.
