is a measurement of energy. BTU is commonly used to measure the energy content of various fuels and steam. One BTU is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit.Clean Air Act Amendments of 1990 represent a major overhaul of the earlier

Changes include revised provisions for attainment and maintenance of National Ambient Air Quality Standards, mobile sources, hazardous air pollutants, and other assorted air quality issues. In addition, it establishes guidelines for reductions in air pollution. The Act also specifically limits sulfur dioxide and nitrogen oxide emissions of power pl [..]

is the simultaneous production of two or more forms of useable energy from the combustion of a single fuel source. Because cogeneration uses the waste energy, which is vented in a traditional power plant, the process is 50 to 70 percent more efficient. Most cogeneration systems are designed to simultaneously produce electric power (to be used on si [..]

refers to utility programs intended to affect the timing or amount of customer electricity use. These include energy efficiency programs aimed at reducing the energy required to serve customer needs and programs that shift electricity demand to reduce peak loads or to make more economic use of utility resources.

is the ability of a generating unit to increase or decrease generation, or to be brought on line or shut down at the request of a utility's system operator.

manages programs of research, development and commercialization for various energy technologies, and associated environmental, regulatory and defense programs. DOE announces energy policies and acts as a principal advisor to the President on energy matters.

is the ability of a power plant to produce a given output of electric energy at an instant in time, measured in kilowatts or megawatts (1,000 kilowatts).

, broadly defined, is the capability of doing work. In the electric power industry, energy is more narrowly defined as electricity supplied over time, expressed in kilowatt-hours.

is the first comprehensive federal energy law promulgated in more than a decade. The act will help create a more competitive U.S. electric power marketplace by removing barriers to competition resulting from the Public Utility Holding Company Act of 1935. By doing so, EPAct allows a broad spectrum of independent energy producers to compete in whole [..]
