Power is the rate at which Work is performed.

Explanation:

In general we can write:

#"Power"="Work"/"time"#

basically it tells us how "fast" we transfer Energy.
Consider an example:
You need to take one truckload of bricks to the third floor of a building.
You can take the bricks by hand or using a lifting crane; at the end of the day the Work done (against gravity) will be the same in both cases BUT the crane will have done the Work more rapidly than by hand!!!
