Types of Non-Conventional Energy Sources

Non-conventional energy sources are being researched to reduce our dependence on fossil fuels that pollute the environment and leave the United States dependent on foreign countries for resources. Though many non-conventional energy sources are functional, they are not yet as cost effective as fossil fuels.

Types

Non-conventional energy sources include biomass, hydropower, wind power and solar power.

Limitations

Non-conventional energy sources that rely on weather cannot be counted on to supply energy around the clock because wind speeds could be low or the weather could be cloudy for several days.

Geography

Some non-conventional energy sources are limited based on geographic features. Hydropower cannot work where there is now a downhill flow of water, and wind power works best in the plains because of the high wind speed.

Benefits

Non-conventional energy sources emit less pollution into the air than fossil fuels, which reduces global warming and acid rain. They are also renewable resources unlike fossil fuels, which will eventually be depleted.

Potential

Renewable energy accounted for about 9 percent of electricity generation in the United States in 2008 and is expected to continue to grow as oil and natural gas prices rise.
