Hydroelectric Power: How it Works
30 08 2018So just how do we get electricity from water? Actually hydroelectric and coal-fired power plants produce electricity in a similar way In both cases a power source is used to turn a propeller-like piece called a turbine which then turns a metal shaft in an electric generator which is the motor that produces electricity

How a Geothermal Power Plant
How is geothermal energy transported? It is not a surprise that the electricity that is generated with geothermal power plants is transported in the same way as you would with any other power plant (or a wind or solar farm for that matter): Voltage is increased to minimize losses and the current is sent onto the electrical grid
