Geothermal Energy By: Nicole Pytel Evan Grunberger Amy Weinhaus
2
Uses for Geothermal Electricity Santa Monica, CA Heating Iceland 1% of world’s electricity .36% of U.S.’s electricity
3
How does it work? Heat of the Earth’s core Where to drill? Geothermal Reservoirs Dry steam Wet steam Hot water
6
Advantages Very clean, none or little emission Small Land use Most reliable energy source Inexpensive electricity price Perpetual Source of Energy Steam as a byproduct
7
Disadvantages Expensive to build Few spots in US- West Coast Only Only enough to supply ¼ of US electricity demand
8
Where is it now? Alaska California Idaho Hawaii New Mexico Nevada Utah
9
Mainstreaming Will replace coal power plants

Challenges Barriers Transactional Costs: Address institutional barriers to decrease project transactional cost. Technical Unfamiliarity: Make decision makers aware of geothermal benefits and resource locations. Power Market Process: Make utilities, power generators, and regulators aware of geothermal benefits. Leasing, Permitting and Public Policies: Address policy constraints of land use plans, and federal and state requirements. Environmental, Tribal, and Public Perception: Address environmental impacts and educate the public.
