Power Plant Efficiency: Coal, Natural Gas, Nuclear, and More

The result is that less energy is lost in the conversion process. Oil power plant efficiency rates are around 40%. Hydro plants are the most efficient power plants with a 90% efficiency rate. This is because dams funnel water directly to the turbines that generate the electricity, resulting in very little energy loss during the conversion process.
