Credits established by the federal and state government to assist the development of the alternative energy industry. Beginning in 1976, California had a solar tax credit. From 1978 to 1985, both California and the federal government offered tax credits for alternative energy equipment. The state provided a 55 percent tax credit on solar, wind, geothermal and biomass for residential applications. However, the residential tax credits were reduced by applicable federal credits. State commercial tax credits for alternative energy systems in commercial and industrial sectors ranged from 10-15 percent. During this same time, the federal government offered a 40 percent tax credit on residential applications and a 10-15 percent credit on commercial and industrial applications. California in 1990 instituted a new 10 percent tax credit for commercial solar systems in excess of 30 watts of electricity per device. This credit expired December 31, 1993.
Degree of hotness or coldness measured on one of several arbitrary scales based on some observable phenomenon (such as the expansion).
One hundred thousand (100,000) British thermal units (1 therm = 100,000 Btu).

(thermal barrier) - An element of low heat conductivity placed in such a way as to reduce or prevent the flow of heat. Some metal framed windows are designed with thermal breaks to improve their overall thermal performance.
A technology that lowers the amount of electricity needed for comfort conditioning during utility peak load periods. A buildings thermal energy storage system might, for example, use off-peak power to make ice or to chill water at night, later using the ice or chilled water in a power saving process for cooling during the day. See THERMAL MASS.
A material used to store heat, thereby slowing the temperature variation within a space. Typical thermal mass materials include concrete, brick, masonry, tile and mortar, water, and rock or other materials with high heat capacity.

Any stationary or floating electrical generating facility using any source of thermal energy, with a generating capacity of 50 megawatts or more, and any facilities appurtenant thereto. Exploratory, development, and production wells, resource transmission lines, and other related facilities used in connection with a geothermal exploratory project or a geothermal field development project are not appurtenant facilities for the purposes of this division. Thermal powerplant does not include any wind, hydroelectric, or solar photovoltaic electrical generating facility.
(TEOR) - Injection of steam to increase the amount of petroleum that may be recovered from a well.
A study of the transformation of energy into other manifested forms and of their practical applications. The three laws of thermodynamics are: Law of Conservation of Energy energy may be transformed in an isolated system, but its total is constant Heat cannot be changed directly into work at constant temperature by a cyclic process Heat capacity and entropy of every crystalline solid becomes zero at absolute zero (0 degrees Kelvin)
(SETBACK) - A device, containing a clock mechanism, which can automatically change the inside temperature maintained by the HVAC system according to a preset schedule. The heating or cooling requirements can be reduced when a building is unoccupied or when occupants are asleep. [See California Code of Regulations, Title 24, Section 2- 5352(h)]
