1 Renewable Energy II Hydroelectric power systems high initial investment, low operating cost, long life expectancy no emissions; high capacity, reliability reservoirs provide water storage for navigation, irrigation, water supply flood control, controlled discharge for recreation, fishing reservoirs flood valuable land; displacement of towns; cultural history reservoirs may increase evaporation and salinity of water water quality may decline due to impoundment natural fluctuations in stream flow are reduced – flooding reduced, but... temperature regimes are disrupted – cold water released sediment starvation of downstream system Colorado River – Lake Powell, Lake Mead Yangtze River – Three Gorges Dam Nile River – Aswan High Dam

24 Tidal and Wave Power Tidal systems generally require a control dam (‘barrage’) to direct flow through turbines. Some tidal systems have sufficient velocity to drive turbines without impoundment Wave systems - experimental; disappointing to date Geothermal Steam and hot water Hot dry rock – injection and recovery of steam or hot water has been problematic Ground, groundwater and lake geothermal – heat pump system Depend on low-temperature (66-39 F heat exchange provide air conditioning Closed loop systems preferred

29 “Hot’ geothermal systems currently in operation depend on natural recharge of cool surface water which is heated by hot rock or magma in areas of volcanic activity.

30 http://www.quantecgeoscience.com/Q_images/HotDryRockDiagram.jpg Hot dry rock systems require injection of cool surface water and production of steam or hot water from fractured rock at depth. These systems have not been successfully developed to date. Loss of water to dry rock, and possible triggering of earthquakes are ongoing problems.
