This program explores wind power's alternative energy production in today's oil-dependent economy - how it works and the environmental factors that scientists are researching.
Solar Power – An Alternative Energy Source
Part of the Series: Show Me Science Series - Advanced
Alternative energy sources are being researched and developed to improve efficiency and reduce costs. Fluctuating costs of oil, coal and natural gas, along with their possible negative effects on the environment, has made energy sources such as wind and solar more cost-competitive with fossil fuels. More energy strikes the Earth…
Gas Turbines – Energy Powerhouses
Part of the Series: Show Me Science Series - Advanced
In a gas turbine, the linear motion of gas causes rotors to spin, ultimately creating electricity. The forward rotating blades pump air under high pressure into the combustion chamber where natural gas ignites on contact with the air. At 1,500 degrees Celsius, the stream of gas rushes past the rear…
