This is only cause of water pollution. Other causes are discharge of sewage in water bodies, discharge of industrial waste, use of fertilizers and pesticides, throwing garbage and other human activities.

Thermal pollution, you boob
We get electric power from falling water, and that will last when into the foreseeable future. Hydroelectricity is a renewal energy and has almost no pollution, once the dam is built.
Thermal pollution is a byproduct of the production of nuclear energy.Thermal pollution is a byproduct of the production of heat. A foundry, for example, produces much thermal pollution in the process of forging steel.

They decrease the amount of electricity you use which in-turn causes less pollution. (Pollution made by the production of the electricity through means of burning coal or water generators.) It'll also help you cut down on your electric bill.
The primary pollution associated with obtaining energy from wind power is noise pollution, caused by the sound of the rotating turbines. Additionally, there may be minor pollution during the manufacturing and transportation of wind turbine components, but this is typically minimal compared to other forms of energy production.
Local heating of river water (usually due to industrial cooing or energy production) is thermal pollution.
Hydro electric. No waste or pollution. Just using gravity and water, provided from potential energy of the height of water.
