We have traditionally used fossil fuels to provide most of our energy needs. These fossil fuels, like gasoline and coal, have some significant disadvantages. First, the world's supply of these nonrenewable resources is diminishing. Second, the prices continue to skyrocket, making it unaffordable for many people. Third, fossil fuels are damaging to the environment, because of this we are starting to look at alternative energy sources. We really need to look carefully at these sources. Fossil fuels will not be around forever, and we are currently using them as if we have an unlimited supply. Fortunately, there are other options, many of which do not have the same concerns as fossil fuels, as these alternative sources are environmentally friendly, renewable, and more affordable in some cases. Some types of alternative energy are solar, hydro, biomass, wind and nuclear power. |
