The second alternative energy source is hydro electricity. This source can be complicated though seeing as you need to live near a strong steady current of water in order for this way of acquiring power to be affective. It is also the most costly of the three ways. Mostly due to the building of a water mill needed to use this method. Low water levels and drought can negatively energy impact energy generation; the surrounding aquatic ecosystem aquatic ecosystem can be harmed by the building of dams and turbines.
Wind power is an important aspect of alternative energy on a large scale, wind power is extremely affordable. Nearly 15,000 mega watts of wind power could power more than 3 million households. The problem is getting that many homes to change to this source of
