Energy Energy In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by
Jeffrey Energy Center Jeffrey Energy Center Jeffrey Energy Center (Jeffrey EC) is a sub-bituminous coal-fired power plant located in Emmett Township, Pottawatomie County, seven miles (11 km) northwest of St. Marys, Kansas. Jeffrey EC is jointly owned by Westar Energy, Topeka, Kansas and Aquila Corp., Kansas City, Missouri. Jeffrey EC is composed of three separate 800-MW units providing a name-plate energy center capacity of 2.16 gigawatts. Unit 1 began operation in 1978, unit 2 in 1980 and unit 3 in 1983. Jeffrey EC is a typical modern coal-fired energy center. Its primary mission is to convert the chemical energy available from its Wyoming
