This hypothetical graph shows how daytime and nighttime temperature vary in the vicinity of a large city. Notice how daytime temperature is higher over heat-reflecting buildings and lower over a water body. The urban heat island effect causes cities to run warmer than surrounding rural areas, especially at night. Development produces heat islands by replacing vegetation, particularly forests, with pavement and other urban infrastructure.

Every year, the United States consumes more than 3 trillion KWh of electricity. This power is generated by coal-fired power plants, nuclear plants, solar panels, hydroelectric damns, wind turbines, geothermal wells, and other sources and it requires water to produce.

Reservoir Construction is slowing is U.S

You need lots of water and a lot of land where you can build a dam and reservoir, which all takes a LOT of money, time, and construction. The trend for the future will probably be to build small-scale hydro plants that can generate electricity for a single community.
