16. What power sources and what kind of energy do we use in space? Where do we get those? (A K2S Question)

From The Space Library

Well, our favorite energy is electricity and we use a lot of it in space. We use it for lighting, heating, communications, motors, and many other things. We can produce electricity using fuel cells, large arrays of solar cells, solar dynamic generators—for example, parabolic mirrors that concentrate the Sun's rays on a sodium pump, nuclear generators, and of course, batteries. If we had a base on the Moon or Mars, we might mine minerals to use in electrical power generators.
