They are source of electrical energy.

nuclear power plants
The source of energy in almost all nuclear power plants is fission or the splitting of the atom. There are a few experimental fusion power plants, (or the joining of the atoms), but, there are few of them, since the energy needed to produce fusion is extremly high, and only last a few seconds. Around 99.99% of nuclear power plants are fission power plants.
Some advantages of power plants are clean source of energy and efficient. Disadvantages of power plants are dangerous and is difficult to dispose of waste.
Hydroelectric power plants
Hydal power plants convert mechanical energy into electrical energy. Hydal power plants use flowing water as a source of mechanical energy. Electricity generated by flowing water from dams is called hydal power.
Nuclear power plants and fossil fuels such as petroleum.

No. Some forms of renewable energy (e.g. solar cells) are much less efficient than conventional energy sources. Modern coal and natural gas power plants are about as efficient as it is possible to make an energy source. Hydroelectric power plants are about the only renewable energy source with efficiency near coal and natural gas power plants.
