Okay, I'll add wind...That I think is more or less a complete list...

Off the top of my head...

1) Nuclear: Energy is derived from the heat produced by nuclear fission (similar to steam engine, only uranium is used instead of coal)
2) Solar: Solar panels are used to harness the sun's heat.
3) Wind: Popular in Europe, "wind farms" consist of windmills which harness the kinetic energy f the wind.
4) Hydroelectric: Most famous of which is probaly the Hoover dam, water's movement is used to generate electricity.
5) Fuel: Especially coal, these power plants burn fuel to power a steam turbine engine, which is in turn used to generate electricity.

There may be a few other types...

Thermal power plants are classified by the type of fuel and the type of prime mover installed.

By fuel:
Nuclear power plants use a nuclear reactor's heat to operate a steam turbine generator.
Fossil fuel powered plants may also use a steam turbine generator or in the case of Natural gas fired plants may use a combustion turbine.
Geothermal power plants use steam extracted from hot underground rocks.
Renewable energy plants may be fuelled by waste from sugar cane, municipal solid waste, landfill methane, or other forms of biomass.
In integrated steel mills, blast furnace exhaust gas is a low-cost, although low-energy-density, fuel.
Waste heat from industrial processes is occasionally concentrated enough to use for power generation, usually in a steam boiler and turbine.

[By prime mover:
Steam turbine plants use the pressure generated by expanding steam to turn the blades of a turbine.
Gas turbine plants use the heat from gases to directly operate the turbine. Natural-gas fuelled turbine plants can start rapidly and so are used to supply "peak" energy during periods of high demand, though at higher cost than base-loaded plants.
Combined cycle plants have both a gas turbine fired by natural gas, and a steam boiler and steam turbine which use the exhaust gas from the gas turbine to produce electricity. This greatly increases the overall efficiency of the plant, and most new baseload power plants are combined cycle plants fired by natural gas.
Internal combustion Reciprocating engines are used to provide power for isolated communities and are frequently used for small cogeneration plants. Hospitals, office buildings, industrial plants, and other critical facilities also use them to provide backup power in case of a power outage. These are usually fuelled by diesel oil, heavy oil, natural gas and landfill gas.
Microturbines, Stirling engine and internal combustion reciprocating engines are low cost solutions for using opportunity fuels, such as landfill gas, digester gas from water treatment plants and waste gas from oil production.

Other power stations use the energy from wave or tidal motion, wind, sunlight or the energy of falling water, hydroelectricity. These types of energy sources are called renewable energy.

Hydroelectricity:
Main article: Hydroelectricity
Hydroelectric dams impound a reservoir of water and release it through one or more water turbines to generate electricity.

Pumped storage:
A pumped storage hydroelectric power plant is a net consumer of energy but decreases the price of electricity. Water is pumped to a high reservoir during the night when the demand, and price, for electricity is low.
