Hydro energy source from rivers, lakes and reservoirs can all be used to generate clean renewable energy. Hydroelectric power is a proven and mature technology that has been supply electrical power around the world for many years. But small scale hydro power plants used in run-of-river or low-head hydro schemes still remain under exploited. Hydropower energy based on renewable sources, reduces pollution and emissions of greenhouse gases thereby having positive impacts on our quality of life. Hydro energy production is an important resource for many countries and was once the only renewable energy source being exploited
Waterwheel designs use shaped buckets or blades transfer the kinetic energy of flowing water into a rotary movement of a shaft. Waterwheel deigns include overshot, breastshot and undershot designs use the gravitational effect of water pushing against the buckets or blades in different ways. Many factors influence the performance of each waterwheel design including are the number of buckets, wheel diameter and width, bucket shape and rotational speed.
