Hello Ankit,
Energy and power are closely related but sre not the same physical quantity. Energy is the ability to cause change, power is the rate energy is moved, or used. Energy is the capacity to do work. It is the power integrated over time.
Work is done when a force produces motion. And for doing work energy is required. This energy we get from the food which we eat and if work is done by machine, then energy is supplied by fuels or by electricity.
Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat.
Hope it helps.
Good Luck!
