QUESTION: How can we get energy on Mars? ANSWER from Steve Wall on January 19, 2000: Excellent question. Think about how you get energy on Earth and see how many of those ways would work on Mars. My list of energy sources on Earth includes running water (maybe not likely on Mars), wind (but think about how the Mars atmosphere is thinner, so maybe the windmills need to be different), nuclear power, solar energy (remember the sun is a lot further away from Mars so its not as bright), and chemical (burning fuel or combining chemicals that give off energy). For chemical energy, remember that you might have to bring the fuels or chemicals with you, so that makes it harder.
