INTRODUCTION
given amount of water falling a given distance will produce a certain amount of energy. The head and the discharge at the power site and the desired rotational speed of the generator determine the type of turbine to be used. The head produces a pressure (water pressure), and the greater the head, the greater the pressure to drive turbines.

Power Plant Efficiency: Coal, Natural Gas, Nuclear, and More
The power plant efficiency calculation divides 3,412 British thermal unit (Btu) (the equivalent of 1 kWh of electricity) by the heat rate. For example, if the heat rate is 7,500 Btu, you''d divide 3,412 by 7,500 and get a 45% efficiency rate. In traditional power plants, electricity is generated by burning a fuel source such as coal.
