Hydroenergy is the world’s largest and cleanest source of renewable energy. If you have a reliable stream, a DIY hydro system can be a very cost effective way to generate power. Since hydro gives 24-7 generation, the energy from even low power hydro generators adds up.

Simple, and cheaply made water turbine. The 36 cups are made from 7 cm diameter PVC-pipe and bolted onto a bike wheel. In this particular video, the wheel is not connected to any load, and the thread and the pulleys only shows a way to transport the power away from the wheel.// Audun

In recent years scientists are in a constant search for alternative energy sources because in recent years conventional energy sources have started to decrease significantly.

So engineers design many of these technologies. In some areas, water is a reliable, clean and inexpensive renewable energy source suitable to replace fossil fuel-burning power plants.
