GEOG 339 Chapter Notes - Chapter 13: Concentrated Solar Power, Water Cycle, North Sea Oil
Document Summary
Overly vague statements about the potential for renewables. For wind and solar, statements of the total amount of energy received in a certain area without providing any information about the very small fraction of total energy that is technically (or economically) capturable. Sustainable energy, david j. c. mackay the developed world gets 80% of its energy from fossil fuels. Unsustainable: easily-accessible fossil fuels will run out at some point. Burning fossil fuels is having a measureable and very-probably dangerous effect on the climate continued rapid use of north sea oil and gas reserves will soon force britain to depend on imports from foreigners. Photovoltaic panels; cover 5 to 10% would provide 50 kwh/d per person. Offshore wind farms; sea-area twice size of wales would provide 50 kwh/d per person three strategies for eliminating he gap reduce energy demand: Population reduction lifestyle change changing to more efficient technology the other strategies for eliminating the gap increase energy supply:
