Power and energy are closely related.
Energy is a measure of the amount of work something has done or can do. It is measured in Joules in a laboratory, calories in certain other fields such as food and other units such as KWH for electrical supplies. As an example, a battery can provide a certain amount of energy which will be used up as the battery delivers a current to a circuit.
Power is the amount of energy used or transferred in a certain amount of time so it is a measure of the rate of transfer of energy. It is measured in Watts. One Watt is equal to one Joule being used or transferred each second. Looking at the battery example once again, if the battery delivers energy at 3 joules every second, then its power output is 3W.
