Electric energy is produced in the generators. By using the principle of electromagnetic induction, the magnetic field around conducting wires is changed and this creates the potential difference. This results in the formation of electric energy. Show More ...
Can the heat energy be stored or used? The SWG3 Arts Centre in Glasgow. Scotland uses a system called Bodyheat, which can use body heat of the dancers as a source of energy.In the arts centre, there are some air collectors taking in the heat produced by dancers. The heat goes ...

How is energy efficiency calculated? To learn more about the energy efficiency of devices, it is important to know the calculation used to assess performance in terms of the ratio of energy used to energy produced. To determine the exact figure that corresponds to the efficiency of a system, ...
How is Geothermal Energy Produced? Wells of up to a mile deep or more are drilled into underground reservoirs to tap into the geothermal resources. These resources can be exploited from naturally occurring heat, rock and water permeability or through enhanced geothermal systems, which enhance or cr...
