As the use of alternative energy sources increases, the consumption of the Earth's fossil fuels will also decrease. One watt of energy that is used by solar cells is one less watt used by power plants burning oil or coal. If society hopes to see the next generation have the resources needed to heat homes and drive cars, alternative energy sources are needed today.
Fossil fuel is the most common source of energy today, but it is not considered clean energy. There are various other sources of alternative energy that must be incorporated if the next generations are expected to have energy. Water, wind, the internal heat of the Earth, and the sun are all being used to create energy. Geothermal energy and solar energy are more common. Homes are being heated and cooled, cars are being driven, and electricity is used all from these various alternative sources of energy. All are examples of clean energy, which is better for the environment because it does not cause pollution.
