Hydro
power is another source of clean, plentiful renewable energy. Widely used
in countries such as Switzerland and France, they provide high efficiency
and are a reliable source of power.
New
developments include micro turbines on waste waters and other artificial
streams.
While some projects are huge and costly, micro turbines are a cost
efffective way to generate electricity without damaging the environment.
They can be fitted on low head situations as well as high head (pelton
turbine).
