Hydropower Types of water power Hydroelectric power
 Hydroelectric power is a means of conserving the energy. Large dams are still being designed. Apart from a few countries with plenty of it, hydro power is normally applied to peak load demand because it is readily stopped and started. Nevertheless, hydroelectric power is probably not a major option for the future of energy production in the developed nations because most major sites within these nations are either already being exploited or are unavailable for other reasons, such as environmental considerations.
