Abundant power is needed to significantly explore and expand into space. A robust power source is needed that can provide high energy and power density while being independent of location, environment and application. The primary energy alternatives that are available in the near-term are discussed below.Solar PowerUsing the sun as an energy source in space is often the preferred option, but is limited in power density and is location specific; if you’re ever in the sun’s shadow or in a dusty/cloudy environment, or as you move deeper into the solar system the sun becomes a poor energy source. Even on Earth, the sun is not practical as a source of baseload electricity. Solar power on the Moon is significantly hampered by the 28 day cycle (i.e. 14 days of darkness). The technology to efficiently and reliably store energy in the deep cold on the lunar night presents substantial challenges, and would likely be more complex and heavier than the solar power system itself. On Mars, the diminished sunlight decreases the value of solar power, but it is the dust, and more importantly dust storms that make solar power unattractive. The potential of a protracted dust storm will require more baseload ...
