A type of energy or fuel consumed in a building. In the CBECS, information about the use of electricity, natural gas, fuel oil, district heat, district chilled water, propane, wood, coal, and solar thermal panels in commercial buildings was obtained from the building respondent. In most tables, wood, coal, and solar thermal panels are included in the “Other” category under "Energy Sources." (See Electricity, Natural Gas, Fuel Oil, District Heat, District Chilled Water, Liquefied Petroleum Gas [LPG], Propane, Wood, Coal, and Solar Thermal Panels.)
A potential source for electricity, e.g. water, coal, oil, gas, uranium.
High voltage electricity, radiowaves, flashes of light, or another laser used to excite the laser medium. Also indirect pumping schemes such as rapid adiabatic expansion, or rapid cooling by contact with gas or dust.
Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy.
High voltage electricity, radio waves, flashes of light, or another laser used to excite the laser medium.
A substance, such as oil, natural gas, or coal, that supplies heat or power. Electricity and renewable forms of energy, such as wood, waste, geothermal, wind, and solar, are considered to be energy sources.
Raw materials that are converted to electricity through chemical, mechanical or other means. Energy sources include coal, petroleum and petroleum products, gas, water, uranium, wind, sunlight, geothermal and other sources.
The primary source that provides the power that is converted to electricity through chemical, mechanical, or other means. Energy sources include coal, petroleum and petroleum products, gas, water, uranium, wind, sunlight, geothermal, and other sources.
A source that provides the power to be converted to electricity e.g. hydro, solar, wind, biomass, fossil fuel, nuclear fuel.
the origin of the light, heat, or electrical energy people use
Any electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other source.
Matter or a system from which on or more forms of energy can be obtained. For instance, natural gas is a source of thermal energy, and sugarcane is a source of chemical energy.
Raw materials or natural phenomena that can be converted to electricity through chemical, mechanical, or other means. Includes fossil products (coal, petroleum, natural gas, etc.) water, uranium, wind, sunlight, geothermal, and other sources.
A type of energy or fuel consumed by the household. For this report, the energy sources identified are electricity, natural gas, fuel oil, kerosene, liquefied petroleum gas (propane), wood, coal, and solar energy. (See Electricity, Natural Gas, Fuel Oil, Kerosene, Liquefied Petroleum Gas [LPG], Wood, Coal, and Solar Energy.)
