Alternative energy sources include hydroelectric, wind, solar, geothermal, biomass, and nuclear power. Currently, these power sources do not produce a large percentage of the worlds’ energy needs. Each energy source has positive aspects and drawbacks, but the technology is continuously improving. Due to the environmental issues caused by fossil fuel energy sources, it is very likely that the use of these alternatives will continue to rise. The energy demands of the world continue to grow and new, clean energy sources are more important than ever.

In recent years, more and more car companies are introducing cars that are powered by electricity. These cars are run on batteries that are charged with electricity, and can simply be plugged in at home or at a special charging station at rest areas. Some of the current models can charge in as little at 45 minutes or up to a few hours depending on the battery. Many of these cars can travel 100 miles or more on a single charge and battery technology is continually improving.
