    You can use gravity in the form of a waterfall. But you can't make a stand alone system without the waterfall. That would mean an endless cycle with only energy output. You are defying the first law of thermodynamics.

    Google "hydroelectric power" for information. The simple answer is: falling water causes the turbine to rotate in a generator.

    According to this Wikipedia article, the largest hydroelectric plant currently produces around 20,000 MW. There are also smaller capacity plants.
