no, in fact it is very cheap and creates no polution whatsoever.....but the dams are hard to take down though..
China
no it is cheaper
Once the dam is built and the power plant installed, there are no fuel costs and no pollution
they are eco friendly because no pollution is caused by them .
Yes.But I think it's pretty expensive.
Hydro power is expensive up front in a large scale but eventually pays for itself. This is particularly true with hydroelectric dams which power large areas.
Because neither burns fossil fuel to create energy, and neither causes pollution.
Hydroelectric power is clean, safe, and efficient. Building a dam is expensive, but the water is free and is naturally renewed by the water cycle. Unlike power plants that burn coal or oil, hydroelectric plants do not contribute to air pollution. But flooding the land behind a dam can destroy wildlife habitats as well as farms and towns. In addition, the dam forms a barrier across the river. It may prevent fish from traveling to the parts of the river where they usually lay their eggs and hatch their young.
False, in fact hydroelectric is one of the cheapest form of energy available. the only possible expensive part if it is building the dam or whatever else the build
Hydroelectric power is made from water.
Flood Control, Hydroelectric Power Generation
the problem with mining is that it creates noice and exhaust pollution when sending it to power stations
