ENERGY 303 Lecture Notes - Lecture 13: Fossil Fuel, Demand Curve, Hot Dry Rock Geothermal Energy
Document Summary
Wind energy capacity in the us: texas has the highest wind power capacity of 12,212 mw, very little wind power capacity back in 1999. Global trends in wind energy capacity (the us graph would look similar: dramatic growth in wind power capacity over the past decade. Pros and cons of wind: advantages, renewable, no direct co2 emissions, technology available, disadvantages/problems, land use and environmental consequences (mojave desert example, bird deaths from wind turbines, not constant supply (generation vs. demand; intermittence, high capital cost. Overall cost about 6-9 cents/kwh: not sure that it"s true that high cost has been a major deterrent. Boundaries of tectonic plates: locations of high heat flow out of the earth: plate boundaries, ring of fire, reference picture. Locations of identified geothermal resources: hottest known geothermal regions, reference picture. The importance of a steep geothermal gradient : temperature gradient data, need steep geothermal gradient.
