Solar energy . . .

-- is renewable (it can't be used up)

-- varies with location  (more concentrated in the Tropics,
                                  more spread out near the poles)

-- is expensive to set up equipment for, but inexpensive to use after that

-- varies with time of day (you don't get any at night)

This is kenetic energy.
