I would guess that those are the methods currently used - usually burning some fuel, or using hydraulic energy.
Hydroelectric power is the cheapest renewable energy source for large-scale production. That is, it has the lowest cost to construct and maintain the generating facilities compared to the amount of energy produced. Solar power is the cheapest renewable energy source for small-scale use, such as pocket calculators, LED lights, and remote (small) electrical appliances.
Assuming it is used to produce electricity, it will be sold in kWh, or MWh probably on a commercial scale.

You don't. But coal is an economical fuel. One method of producing electricity on a commercial scale is with steam. Coal provides an inexpensive source of heat to heat water to steam, which is directed through turbines which in turn drive generators. You can do the same thing with falling water (without the steam) if you have a large enough waterfall, or you can use a different heat source like natural gas or atomic energy. Coal is sometimes more economical.
