Wind Energy

Currently the world's population uses three main energy sources: fossil, renewable, and fissile. The fossil energy sources are petroleum, coal, natural gas, bitumen, oil shale, and tar sands; the renewable energy sources include biomass, solar, wind, geothermal, and hydropower; and the fissile energy sources are uranium and thorium (Demirbas 212). Demirbas also estimates that at the present rate of production, known petroleum reserves will be depleted in less than 50 years (212). Additionally, energy production from fossil fuels results in high greenhouse gas emissions creating critical environmental problems throughout the world. According to Demirbas energy consumption will be double the 1998 level by 2035 and triple by 2055 if the global growth rate of about 2% a year of primary energy use continues (213). The combination of climate change, escalating oil prices and concerns about long-term energy security has put energy at the top of political and policy...
