The Moon Does Not Have Water

But it has energy.

Moon has enough helium-3 to power Earth for five millenniums
25 tons of helium-3 per year will more than suffice to meet mankind’s energy needs....... On Earth, helium-3 is measured in grams, while its reserves on the Moon are estimated at 500,000 tons.
Helium-3 - Wikipedia Hydrogen-1 and helium-3 are the only stable nuclides in existence that contain more protons than they have neutrons.... a light, non-radioactive isotope of helium with two protons and one neutron .... sought for use in nuclear fusion research ..... The abundance of helium-3 is thought to be greater on the Moon (embedded in the upper layer of regolith by the solar wind over billions of years ..... The helion, the nucleus of a helium-3 atom, consists of two protons but only one neutron, in contrast with two neutrons in common helium ..... Its hypothetical existence was first proposed in 1934 ..... Helium-3 is proposed as a second-generation fuel for nuclear fusion in hypothetical fusion power plants, but such plants are still very early in their development -- especially since the first generation has not entered service anywhere, yet.

Helium-3 is a very rare gas with the potential to fuel clean nuclear fusion power plants. However, one of the problems is that the nearest supply of helium-3 is on the Moon.
Lunar Helium-3 as an Energy Source - The Artemis Project
Jun 27, 1999 .... The total supply in the U.S. strategic reserves of helium is about 29 kg ..... In their 1988 paper, Kulcinski, et al. (see ref note below), estimate a total of 1,100,000 metric tonnes of He3 have been deposited by the solar wind in the lunar regolith. Since the regolith has been stirred up by collisions with meteorites, we'll probably find He3 down to depths of several meters. ..... The highest concentrations are in the lunar maria; about half the He3 is deposited in the 20% of the lunar surface covered by the maria...... To extract He3 from the lunar soil, we heat the dust to about 600 degrees C....... We get most of the other volatiles out at the same time, so we'll be heating up the rocks anyway. (To get the oxgyen out, we'll turn up the furnace to about 900 deg C
