Hydroelectric power generation is the act of using moving water to generate power. Historically this was done using paddle wheels in streams to turn grinding stones for making grain flour. Today, most hydroelectric dams are of a larger scale. A hydro dam location is chosen because it has a large amount of flowing water that can exit the dam at a much lower height than it was taken at. As in a waterfall, the waters falling through the dam generators speed up and drive turbines, generating power.
Generating Electricity Coal is used to generate electricity by burning it. The heat is then used to run a heat engine, which utilizes water steam to turn electric turbines. Coal was the fuel that started the industrial revolution, and it’s use continues to grow today. Coal-fired electricity production accounts for more electricity than any other […]
“Wind Power” is the extraction of energy from the wind. Common techniques use a tower with a set of propeller blades that will spin when wind blows against them. Wind power is a renewable form of energy because wind is caused by the uneven heating of the earth by the sun.
