  1. Geothermal Energy By: Billy Simon

  2. Geothermal Energy: is thermal energy generated and stored in the earth Thermal Energy: is energy that determines the temperature of matter Definition

  3. Dry Steam Plants- directly use geothermal steam to turn turbines Flash Steam Plants-pull deep, high pressure hot water into lower pressure tanks and use the resulting flashed steam to drive turbines Binary- Cycle Plants- pass moderately hot geothermal water by a second fluid with a much lower boiling point than water. This causes the second fluid to flash to vapors driving the turbine. Collection of Geothermal Energy

  4. Sustainability: it is a globally sustainable energy source Availability: emerging technologies will continue to make it available in more areas Cleaner: it is, on average, a cleaner energy source than fossil fuels Safety: it is less dangerous, to develop and use than fossil fuels Pro’s of Geothermal Energy

  5. Is it more cost efficient to build a geothermal power plant compared to a power plant that uses natural gas? How many years will it take for the pay back of the geothermal power plant to equal the cost of fuel used by a natural gas power plant? Question?

  6. Cost to build a Geothermal Power Plant? $3,400 per kw installed A 100 mw Power Plant would cost $340,000,000 Cost to build a Natural Gas Power Plant? $1,200 per kw installed A 100 mw Power Plant would cost $120,000,000 Data 1

  7. It takes 7cubic ft. of natural gas to produce 1 mw for an hour 7000 cubic ft. of natural gas = 100 mwh Natural gas prices: 1000 cubic Ft. = $7.00 7000 cubic Ft. * $7 = $49,000 of fuel per hour $49,000 * 24 * 365 = $429,240,000 It would cost $429,240,000 a year to fuel a power plant with natural gas Data 2

  8. A Geothermal Power plant cost $340 million to build but doesn’t have to pay for fuel. Leading to a cost of $340 million overall A Natural gas fueled power plant cost $120 million to build but it cost $429,240,000 annually to purchase natural gas to fuel it. Leading to a cost of $549,240,000 overall Data 3

  9. I found that within a year the Geothermal power plant would be more cost efficient than a natural gas power plant. It would save approximately $200 million in the first year. Results

  10. I assumed the power plants were operating 24 hours a day, 7 days a week I also assumed that both power plants had comparable maintenance costs Limitations

  11. Geothermal energy from the earth is a cleaner and cost efficient form of energy More geothermal power plants should be built in order to help prevent pollution at a cheap cost Questions? Conclusion
