Alternative Energy: Hydropower
... Figure 1: Historical hydroelectric energy generation in the U.S. First of all, hydroelectric power is not as cheap as we often think. While there is no cost for fuel, as there is with coal and oil, there is a heavy cost for construction, upkeep, and land rights. The hydroelectric facilities that wer ...
