Further, hydropower is not expensive as compared to energy produced from nuclear energy or fossil fuels. The advantage of hydroelectric reservoirs is that they are able to tackle daily, seasonal, and peak loads. For instance, when the demand of electric falls, the reservoirs or dams store water while some installed electricity generators are used to store excess energy (Harvey and Brown 33).
