Hydro power depends on running water to turn the turbine and produce electricity. A small scale Hydro Power Generator is often called Micro Hydro Electric Generator. A Micro Hydro Plant usually produces electricity below 100kW.
Recent interest in Small Scale Hydro Plants as part of movements in producing more cleaner and greener energy has attracted many researches to study and develop many improvements in Micro Hydro Technology.
When we talk about energy we should never forget to mention such things as Hydro-Electric energy, which at one point in the last decade accounted for almost 22% of our energy resources. Hydro-electric generation really makes sense as the water keeps flowing in an unending cycle as rain fall brings it in and then it attempts to go back to the sea or into a lake.
One thing that not a lot of people consider is that during drought years there is less water to go through hydro-electric generations stations and this causes a great demand for energy on other generation stations which use coal, nuclear or some other form to make the energy. One consideration, which luckily is not an issue this year is the Colorado River and the water usage to three states post Hoover Dam. As the water flows down toward Mexico it is used to generate electric energy, but in years of severe drought we cannot allow the water to flow out of Lake Meade, NV as fast as we wish to generate the power we need.
