A geothermal power station uses thermal energy from deep underground to drive a steam turbine and generate electricity.
Calculate the efficiency of the geothermal generator.
Use the equation:
efficiency=useful energy transferred by the generator in one secondtotal energy supplied to the generator in one second \text{efficiency} = \frac{\text{useful energy transferred by the generator in one second}}{\text{total energy supplied to the generator in one second}} efficiency=total energy supplied to the generator in one seconduseful energy transferred by the generator in one second
