what is generation power?

Question

the question is under advanced electricity and magnetism

Answer 1

Rotating turbines attached to electrical generators produce most commercially available electricity. Turbines may be driven by using steam, water, wind or other fluids as an intermediate energy carrier. The most common usage is by steam in fossil fuel power plants or nuclear power plants, and by water in hydroelectric dams. Alternately, turbines can be driven directly by the combustion of natural gas or oil. Combined cycle gas turbine plants offer efficiencies of up to 60%. They generate power by burning natural gas in a gas turbine and use residual heat to generate additional electricity from steam. Wind turbines generate electricity by using the wind. Solar chimneys use wind that is artificially produced inside the chimney by heating it with sunlight. Solar parabolic troughs and solar power towers concentrate sunlight to heat a heat transfer fluid that is used to produce steam to turn a turbine. Small electricity generators are often powered by reciprocating engines burning diesel, biogas or natural gas. Diesel engines are often used for back up generation, usually at low voltages. Biogas is often combusted where it is produced, such as a landfill or wastewater treatment plant, with a reciprocating engine or a microturbine, which is a small gas turbine.

Answer 2

Rate of change of flux.
