What energy sources would be the easiest and fastest to harness?

Is there wind on Mars that could be used to feed the rovers ?

Is there anything on Mars (in the air, soil, or whatever) that could be used by and for the rovers ?

What is the total amount of energy in joules taken to achieve an orbiter mission, and what percentage is self generating after launch?

Will energy be able to be "teleported" to Mars in the form of radio waves by just putting a lot of energy into one wave? (there is suprisingly no known limit to how much energy can be put into a light ray)

If UFOs existed, what would they probably be powered by? Would they be powered by solar power, geothermal power, wave power?

why have NASA decided to power the Mars Science Laboratory with nuclear energy instead of solar energy? Would'nt solar energy make the mission lorger lasting?

Is wind powerful enough to generate energy as here on earth?

Can we transfer the energy that generated from Mars to Earth by microwaves and coolected by Earth in order to let Earth has a clean energy if we can source new clean energy source from Mars?

if we were to settle on mars what power source could we use?
