Abstract from DBPedia
    Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes by the electric power industry through an electric power grid. Electric power is usually sold by the kilowatt hour (3.6 MJ) which is the product of power in kilowatts multiplied by running time in hours. Electric utilities measure power using an electricity meter, which keeps a running total of the electric energy delivered to a customer. Electrical power provides a low entropy form of energy and can be converted into motion or other forms of energy with high efficiency.

    電力(でんりょく、英: electric power)とは、単位時間に電流がする仕事(量)のことである。なお、「電力系統における電力」とは、単位時間に電気器具によって消費される電気エネルギーを言う。国際単位系(SI)においてはワット[W] が単位として用いられる。 なお、電力を時間ごとに積算したものは電力量(electric energy)と呼び、電力とは区別される。
