1. Geothermal Powered House Sonoma, California

2. Geothermal Power Plant Water and the earth are used to create electricity It is the same process to create electricity as with fossil fuels, but no fossil fuels are used 3 types Dry steam Flash steam Binary cycle http://www.youtube.com/watch?v=3o6Me3 gVXtc&feature=related

3. General Advantages and Disadvantages No fossil fuels used No need to transport Only admissions are steam and small amounts of gases Only able to be built on or near tectonic plates

4. Dry Steam Hot steam and or water from the ground is routed to a turbine which powers a generator that creates electricity

5. Flash Steam Uses hydrothermal fluids above 360°F Fluid is put into low pressured tank which causes it to vaporize or “flash” Vapor→ turbine→ generator→ house Extras can be “flashed” again

6. Binary Cycle Low temperature water mixed with a secondary fluid (hence binary) are sent through a heat exchanger which causes the secondary liquid to flash which powers turbines

7. Binary cycle (continued) Closed system so produces no waste New and up and coming more and more of these kind of plants are being built

8. Tankless instant water heater Tankless water heaters use natural gas or propane to heat water only when water is needed When a faucet is turned on the heater begins to heat water as it passes through a copper heat exchanger 84% of the energy as heat is used so extremely energy efficient Faucet is turned off and heater also shuts off so uses no phantom power

9. Recycled countertops Old glass that does not break down is broken into small pieces and mixed with fly ash and concrete that also helps the environment rid of these wastes They recycle but are very expensive to make and install they are still a very good choice in your home (see note below)
