Energy is.Energy, abilities which are in what may labor English Energy is called the power used in a certain period of time. Or the distance one is Joule (Joule).Examples of energy including electricity in batteries, chemical energy in food, thermal energy of the water heater. Or potential energy of the water over the dam.Energy can be transformed from one form into another form. By the law of conservation of energy states that in a closed system, the total energy is composed of the power of small portions is constant.The energy that this can"t die. Unless it is changed to be in the form of energy in other forms, for example.Change the light energy from the sun into electrical energy used by households (using solar cells).Change the accumulated energy contained in the water stored in the dam (potential energy) is the energy use and driven dynamo (kinetic energy) of the power plant.There are many variations and energy we can use but not yet used did not invented, such as the energy from nuclear fusion And so on.The difference of energy (energy) and power (power) are as follows.Energy (energy) is the ability to work at one time or distance, such as the lights lighting 100 watts left 24 watch means. We use the energy to 100 × 24 = 2400 watt - Watch or 2.4 kWh or 2.4 electric unit, has to tell the time, or ระยะทางเสมอ unitIs in work, power) is the rate that was made or volume equations can do, such as car battery size 12V 500A means strength. 12 × 500 = 6000 watts or 6 kW (don"t say can work long).
