Power(watt) is the rate of change of energy. Take energy(joules) divide by time(seconds). u'll get power

Energy is the capacity to produce power
Electrical energy is a form of energy, and can be measured in the same units, Joules in the SI system. Note that 1 watt = 1 Joule/sec. Electrical energy is often expressed in Kilowatthours or Megawatthours, which are the normal ways an electric company measures your usage. 1 Kilowatthour just means a steady power of 1 kilowatt maintained for 1 hour. Since there are 3600 seconds in an hour, 1 kilowatthour = 3600 kilowattseconds.
Now 1 watt = 1 Joule/sec, so 1 Joule = 1 wattsec, 1000 joules = 1 kilowattsec, so 3600 kilowattsecs = 1000 x 3600 Joules = 3.6 x 106 Joules = 1 kilowatthour.
They're the same thing!!!!
not really, they don't even have the same units.
Voltage is the potential energy per unit charge.
ANSWER BY KAKOOLI
The more voltage ( potential difference), the more energy
ohm's law: Voltage=Current x Resistance
power is measured in Watts/W
Voltage is measured in Volts/V
Current is measured in Amps/I/A
Electrical energy/energy is measured in kilowatt per hour (Formula): Energy=Power x Time
Power in watt = Energy in Joule/Time in second
P=E/t , i.e., Watt=J/s
Energy and Power two are most all equal but a small difference between those two. that is Energy doesn't change. But power Power is a rate. describe how something changes with time.
Power is energy expended in a given time.
nuclear power
Thermal Energy is the kind of energy that is related to and/or caused by heat
All current nuclear power plants use nuclear fission to produce energy. For more information on fission and power plants, see the related links.
Energy Is an interdisciplinary engineering science having to do with the efficient
Power is a measure of the amount of work done in a certain amount of time.
Energy is related to power in that power is energy per second. The units for power are J/s, otherwise known as a Watt (W).

Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time

Thermal Energy is the kind of energy that is related to and/or caused by heat
Power is energy divided by time. Solving for energy, energy is power multiplied by time. Work is closely related to energy - work is the amount of energy transferred.
It is related to a power house.Thats because it generates energy.

Power is the rate at which energy is transferred from one object to another or converted from one form to another.
The rate of expenditure of energy is power. To perform work energy is needed. So rate of doing work is also known as power. Unit of energy and work is one and the same i.e. joule. So unit of power is J/s This is also termed as watt.
