Alternative energy
Tuesday, November 11th, 2008Alternative energy is a general term for any form of energy that can be substituted for another form. Natural gas, for example, can be an alternative for coal or oil. Alternative energy is derived from natural, renewable resources such as wind, sun, and water. Popular forms of alternative energy include solar, biofuels (ethanol), geothermal, coal gasification, hydro, and wind power. Alternative energy is the energy component beneath the clean technology umbrella. It includes solar, wind power, fuel cell technology, biofuels and others energy technologies that promote an economic and environmental benefit.
Alternative energy is a popular topic these days. Oil prices are rising; reserves of oil , coal and natural gas are being depleted; and the continued use of nonrenewable fuels poses threats to the environment.
Alternative energy is an extremely important and relevant topic for today’s students. As more emphasis is placed on improving these resources, students need to be aware of their choices and how each alternative energy source works. Alternative energy is not just cost-effective and necessary for foreign policy, it is also required for domestic policy, to promote a sustainable environment and to prevent global warming and the worldwide catastrophe that advanced global warming could create. The cause of environmentalism is becoming increasingly popular, among both experts and ordinary people, politicians and businessmen, liberals and conservatives, scientists and religious leaders.
