The use of the sun to create energy, whether in the form of heat or electricity, is not new. Solar energy has been in use for many centuries.
Advantages of Hydroelectric Energy
Power generated by flowing water is referred to as “hydroelectric energy.” This principle has been used by man, throughout history. It was utilized in ancient times, to mill grains such as corn. In 1878, the Cragside House in England was the first house to be lit by this process. In 1882, hydroelectric energy was used to power two paper mills and a residential building.
