Answer to Question #133122 in Physics for Elvis

Question

A fossil fuel electric-power plant consumes 9800 Btu to produce 1kWh of electrical energy. Calculate the conversion efficiency if 1kWh is equivalent to 3410 Btu.

Answer 1

If 1kWh is equivalent to 3410 Btu then plant produces 3410 Btu. The conversion efficiency then will be:

$$\eta = \dfrac{3410}{9800} \approx 0.348$$

Answer. 0.348 or 34.8%
