The availability of Energy is one of the vital requirements for a settlement on Mars. The following sources are discussed:

Solar

Solar panels provide electricity out of sunlight. There are already experiences with Mars probes. The availability strongly depends on the weather conditions and the daytime. Maintenance effort is low.

Wind

Wind turbines provide electricity out of the atmosphere and can produce lots of energy. Dust storms may have a massive abrasive effect on the rotor blades. The availability strongly depends on the weather conditions.

Nuclear

Nuclear power has been considered as the preferred energy source for most plans for medium- to long-term human expeditions to Mars. It does not depend on weather condition. Vast effort of the nuclear enrichment process.

Thermocouples

Thermocouples provide electricity out of temperature differences. The amount of energy produced with this technology is sufficient for powering sensors or small gadgets for information technology.

Geothermal

Depth drilling can be used to heat buildings.

Open Issues

  • What is the effect (efficiency) of thin air on the wind turbines?
  • Are there scientific theories about the inner temperature on Mars?
  • What is known about nuclear resources on Mars?
