Rate and efficiency are two different things, but can be related. Rate : How many units per period are being completed For example, a car assembly line might be set at a rate of '5 cars an hour' passing through each station. Workers would have an average of 12 minutes to complete their tasks at each station. Efficiency : Staying busy with a task within its established time requirement. For example, using the previous car assembly line, each worker at the station should need all 12 minutes to complete their task -- to be efficient. If the worker can complete their task in 10 minutes, they're not staying efficient... they're standing around idle for 2 minutes waiting for the next task. Note that if for some reason the worker needs 15 minutes to complete their task, they're still being efficient (constantly working) but they did slow down the 'rate' process, probably affecting the other workers after them.
Yes, power is the rate at which work is done.

(physics) the rate of doing work; measured in watts (= joules/second) - See more at: http://www.chacha.com/question/what-is-the-rate-of-doing-work-or-using-energy-(58%26%2345%3B19)#sthash.l6xRuIk4.dpuf
The rate of doing work is known as power, which is the amount of work done in a unit of time. It is often measured in watts (W) or horsepower (hp).

"Power" is the rate of work, or of energy transfer.
Power is the rate of doing work
Power is the rate at which work is done or energy is transferred. It is measured in watts (W) or horsepower (hp).
Power is the rate of doing work or delivering energy whereas energy is the capacity for doing work.
