The main sources of electricity are fossil fuels, nuclear power and renewable energy. Electricity is a secondary source of energy derived from primary sources.Continue Reading
Electricity is a secondary source of energy because it cannot be extracted from the ground, like fossil fuels, or captured from moving phenomena, such as water or wind. Most electricity consumed in the United States has a fossil fuel as its source, according to the United States Environmental Protection Agency. Renewable resources, such as wind and solar, represent a small but growing percentage of electricity sources.
Fossil fuels occur naturally in the earth and are the remains of living organisms from the geological past. They include coal, oil and natural gas, which generate electricity when they burn in large electric power plants.
Nuclear power is a nonrenewable energy source that uses radioactive materials as part of the process of heating water to generate electricity. The process generates zero atmospheric emissions, as stated by the National Academy of Sciences.
Renewable energy sources are naturally replenished and include biomass, hydro, geothermal, solar and wind. Some of these renewable sources are intermittent, such as wind, which can create complications when using them to generate electricity on a large scale.Learn more about Electricity
The negative aspects of biomass energy are similar to those associated with the use of fossil fuels for generating electricity, with the exception that biomass fuels are renewable energy sources. Burning of biomass fuels causes concerns about emissions and water use. Biomass fuels are less efficient and require more land.Full Answer >
Wind power produces economic, energy and environmental benefits: it serves as a domestic fuel source, operates without burning coal and fossil fuels and provides a steady source of electricity. Wind energy comes primarily from turbines, which operate on land and offshore. Siting is another benefit of wind energy, involving turbines set up on private and public lands in order to provide electricity to residences, commercial offices and communities.Full Answer >
According the United States Geological Survey, hydroelectric power offers clean energy without the emissions created by fossil fuels, but it is very location- and precipitation-dependent and can have major land and ecological effects. Hydroelectric dams can require major changes in natural waterways to function, and the dams may disrupt or displace humans and wildlife populations.Full Answer >
As of 2015, Dominion's services include the provision of natural gas and electricity to utility and retail customers in 13 states; the generation of 24,900 megawatts of electric power that is delivered over Dominion transmission lines; and the expansion of renewable energy sources, such as solar power. Dominion also operates one of the largest natural gas storage systems in the United States and manufacturers and markets home security systems, air cleaners, outdoor lighting, surge protectors and energy meters.Full Answer >
