Some examples are solar energy, wind energy, tidal energy.
Usually an "alternative energy source" is one that is not now a major contributor to our energy supplies. That would make "alternative energy" anything that is not based on fossil fuels of one sort or another. Some people exclude nuclear energy from the "alternative" universe
Some of the least expensive types of alternative energy include petroleum, coal, alcohol and biomass. Solar and wind energy are, of course, free of charge.
Some alternative energy sources that do not produce greenhouse gases include solar power, wind power, hydropower, and nuclear power.
