Which Power Plant Emits More Heat: Nuclear or Fossil Fuel?

[ChunkymonkeyI]

Homework Statement

Modern nuclear power plants have an overall efficiency of about 30%. Fossil fuel plants achieve overall efficiencies of 40%. Compare the rate of heat emission from a nuclear plant with that from a fossil fuel plant each of which produces an output power of 1000 MW

Homework Equations

e=W/Qh

The Attempt at a Solution

I don't know where to start because we're only given the efficency and the power but that's not enough information i think

I don't think your formula is useful in this case. It is a more basic efficiency question.

It's kind of like this. Say you are picking berries and you eat 70% of what you pick. After a long hot day, you have 5 pounds of berries in your pail. Can you figure out what you picked and what you ate? If you have trouble with that, try a 50% eating rate first.
