Alternative Energy

Alternative energy is energy that does not come from fossil fuels, such as oil. Alternative energy sources are not completely equal to oil. Alternative energy sources must be considered because the cost of recovering oil exceeds the energy in the recovered oil. Examples of alternative energy are solar energy, wind energy, fusion, geothermal energy and hydroelectric power. Alternative energy sources must be found because oil may not be as available in the future to fuel the modern world.
