There are several hydroelectric power concerns,
* Building a dam/reservoir to harnes water may flood ecosystems and destroy ancestral lands of aboriginal peoples (a UN concern)
* Building the access infrastructure may open up natural forests to hunters and tourists * Doing the above to have electricity to sell out of the country may be seen as unwise by the citizens * Methane from flooded ares affects global warming - a world wide problem
hydroelectric causes noise pollution, but other wise there isn't any pollution caused by it.
The greatest negative effect of obtaining hydroelectric power is the disruption of local ecosystems caused by dam construction. This can lead to habitat loss for aquatic and terrestrial species, altered water flow, and changes in sediment transport, which can significantly impact biodiversity. Additionally, the flooding of large areas for reservoirs can displace communities and affect local economies. These environmental and social consequences often raise concerns about the long-term sustainability of hydroelectric projects.
they are eco friendly because no pollution is caused by them .
No, apart from the destruction of environment/habitat caused by the dams and reservoirs required.
It isn't "caused" by anything. Water goes through a dam and turns a turbine. That turbine creates electricity. Not exactly rocket science. The phrase "hydroelectric power" refers to the technology of intercepting some of the kinetic energy of falling water and converting it to electrical energy. Wherever the process is in use, it's caused by human engineering.
The name of water energy is Hydroelectric energy caused by moving water generating electricity.
Indirectly. Hydroelectric power is generated from flowing water, which is ultimately powered by the sun. Solar energy drives the water cycle by evaporating water from oceans and lakes, creating precipitation that flows through rivers, ultimately turning turbines in hydroelectric power plants.
The nuclear weapons that the super power countries had caused international tensions after World War 2. This caused the Cold war between the US and Russia.

Sun, wind (which is caused by the sun), and hydroelectric (Also a result of the Sun's activity) are a few that do not emit harmful wastes.
