It generates 320 megawatts of electricity. A possible site for a tidal power station is at the Bay of Fundy, between New Brunswick and Nova Scotia. The tidal head difference there is 50 feet. Tidal Electric's concept. Geothermal Power Center for Renewable Energy and Sustainable Technology Geothermal power is produced from heat that is brought from the Earth's interior to ground level by thermal conduction, and by molten magma penetrating into the earth's crust.
Ground water is heated in underground reservoirs to form naturally occurring hot water and steam.
The steam is separated from the water and fed to a turbine, which turns an electric generator. Energy conversion efficiencies From the vertical to the horizontal mech. Gigatons coal eq. The greatest challenge facing humanity in the next twenty years is to preserve our fundamental life support systems in the face of increasingly inequitable and unsustainable production and consumption patterns.
