Energy Units and Conversions. Power = Current x Voltage (P = I V) 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour. (E = P t). 1 kilowatt-hour (kWh) = 3.6 x 10 6 J = 3.6 million Joules.

A calorie (or thermochemical calorie) is a unit of energy in the International System of Units (SI). The symbol for calorie is cal. A calorie is measured as the quantity of heat required to raise the temperature of 1 gram of water by 1°C from a standard initial temperature at a pressure of 1 atmosphere. A calorie is also called a small calorie or gram calorie.

Energy is the capacity of something to do work: If something contains a store of energy it is able to do work. If something does not store energy then it will not work. The law of conservation of energy states that: Energy cannot be created or destroyed, it can only change from one form to another. What this means is that the total amount of ...

Automobiles, for example, are only about 20% efficient in converting the energy stored in gasoline to mechanical work; the rest of the energy is released as heat, either emitted in the exhaust or produced by friction in bearings and tires. The production of electricity by coal- or oil-powered steam turbines (Figure (PageIndex{1})) is can be ...
