Biomass is living or recently dead biological matter that can be used for fuel or industrial production.
Coal is a concentrated form of prehistoric biomass in the form of plant life and is the most abundant fossil fuel produced in the United States.
Energy is known as the “lifeblood of society” because of the essential role it plays in sustaining life on Earth. When it comes to energy, more is better, as history illustrates.
Fossil fuels—coal, petroleum oil, and natural gas — are concentrated organic compounds found in the Earth’s crust. Fossil fuels make modern life possible.
Geothermal energy is harnessed from the natural heat of the Earth. In some cases, this means tapping extremely hot temperatures via steam at great depths. These are known as “heat sinks” and are valuable for their use in creating energy.
Most hydroelectric power comes from dammed water driving a water turbine and generator. Hydroelectricity is dependent on amount of precipitation and will vary somewhat over time.
Natural gas is a principal component of modern chemistry and, as such, plays a central role in our quality of life. Natural gas is colorless, odorless fossil fuel gas that is prized for its cleanliness and its many uses – including energy.
Nuclear power comes from the process of nuclear fission, or the splitting of atoms. The resulting controlled nuclear chain reaction creates heat, which is used to boil water, produce steam, and drive turbines that generate electricity.
U.S. Western oil shale is a fine-grained sedimentary rock which is very rich in organic sedimentary material called kerogen used to make superior quality jet fuel, diesel fuel, kerosene, and other high value products.
Due to its high energy density, easy transportability, and relative abundance, oil has been the world’s leading source of energy since the mid-1950s.
Renewable energy relies upon the natural forces at work upon the earth, including the internal heat represented by geothermal, the pull of lunar gravity as it affects the potential for tidal power, and solar radiation such as that stored through photosynthesis in biomass.
The power of the sun’s radiant energy is what makes life on earth possible. Efforts to harness it in concentrated form and direct it to man’s ends have long been a human pursuit. The current state of technology generally uses two approaches: solar thermal collectors and the more complex design and manufacture of photovoltaic cells.
Wind power is typically generated by large-scale wind farms where they are connected to power grids that distribute their electricity. Though wind power has increased substantially since 1970, it constitutes only a small fraction of U.S. electricity supply.
