WHAT EXACTLY IS ELECTRICITY?
Electricity is electric current that is used as a power source; this electric current is generated in a different power plant and then sent over a power grid to your homes and ultimately to your power outlets.
HOW AN ELECTRIC CURRENT IS GENERATED?
The electric current generation whether from fossil fuels, nuclear, renewable fuels, or other sources is usually based in different ways. Wind power generation has significantly increased in recent years with the help of windmills. In Hydroelectric power plants, the use of water power is generated by electrical power. Solar power plants use the sun's energy to either boil water or directly convert solar energy into electrical energy.
Nuclear power plants also can generate electricity with the help of nuclear fuels. Solar power plants use the sun energy to either boil water or directly convert solar energy to electrical energy.
Ocean thermal energy, tidal energy uses temperature differences between different depths of ocean water to drive a heat engine. Working fluid is ammonia which is in gaseous form at room temperature. Biomass energy conversion uses municipal solid waste burning wastes to drive heat engines. Geothermal energy created by naturally occurring heat in the earth due to radioactive decay. Tidal energy which uses the gravitational pull of the moon on our oceans to drive turbines, and finally we can generate electricity.
