Kinetic energy is this capacity as manifested by the motion of matter. The joule (J) is the common SI unit of energy, where 1 J equals the amount of energy required to increase by one Kelvin the temperature of one gram of water. Other units include kilocalories (kcal), kilowatthours (kWh), and

The major forms of industrial energy are oil, coal, natural gas, nuclear, and hydroelectric. In addition to hydroelectric, industrial energy also includes other technologically complex methods of harnessing renewable energy, including photovoltaics, electricity-generating wind turbines, and geothermal turbines. energy, nonrenewable Forms of energy whose trans-
