According to environment.about.com, “The U.S. Energy Policy Act of 1992 identified eight alternative fuels.” The site lists them, in order, as ethanol, natural gas, electricity, hydrogen, propane, biodiesel, methanol, and “p-series” fuels. A brief description is given of each type of fuel.
Saveenergy.about.com lists the most popular sources of alternative energy, in order, as wind power, solar power, geothermal energy, and hydroelectric energy, as well as listing the pros and cons for each source.
This was answered a week ago; see link. Natural gas would not normally be considered an alternative, nor would electricity inasmuch as almost half the electricity is generated by coal, and almost 90% comes from non-renewables (coal, natural gas, uranium).
