Answer:
No water source is available that can be used for the production of energy from water.
Explanation:
Solar energy, energy from water, nuclear energy, geothermal energy, and wind energy are used to produce electricity on Earth. All these sources are present in large amount on earth but on Mars all sources are available except water so that energy from water can't be produced. It has low temperature of the soil so no production of geothermal energy occurs. Water and oxygen for the survival of humans are important which are not available on Mars which are the potential problems that need to be solved.
