Energy source of the world is primarily dependent on petroleum or Crude Oil which comprises 32% to the total energy production closely followed by Coal (30%) and Natural gas (23%). Nuclear and Hydroelectric energy sources contribute at 5% & 6% respectively, and Wind power (1%) with the remaining 3% coming from solar, wave, tidal, geothermal and biofuels sources.(see Live Commodities)
Electricity is the physical phenomena associated with the flow of electric charges which can be positive or negative. Electricity Generation is the process of generating electric energy from other forms or source of energy. Basically, Electricity is generated by the movement of a loop of wire,or disc of copper between the poles of a magnet. An Electric Generator is a device that converts mechanical energy to electrical energy.
The Electric Generator can be operated by manual hand crank and compressed air. At an Electric power generating station, the sources of mechanical energy are driven by direct-coupled internal combustion engine such as Diesel fueled and other petro-chemicals, turbine fueled by gas, steam turbine heated by nuclear fission reactor, fossil fuel & biomass, and turbines driven by kinetic energy such as hydro-electric, water wave & tides, and wind. Technology had advances to harness solar photovoltaics and geothermal energy to generate electricity. Harnessing a lightning bolt and using the electricity is not easy to overcome
due to obstacles such as; knowing when and where lightning will strike,
capturing, materials that could withstand the sudden surge and transmitting it onto the electrical power grid.
Renewable energy sources include all fuel types and energy carriers,
different from the fossil ones. Renewable energy sources include solar energy,
wind energy, geothermal energy, Biomass from plants or animals, and hydropower from water.
Coal, Crude oil and Natural gas are called "fossil fuels" because they have been formed
from the organic remains of prehistoric plants and animals. While Biofuels include fuels derived from Biomass conversion, such as Bioethanol alcohol from corn or sugarcane, Cellulosic Biomass for Ethanol production that is derived from trees and grasses, and Biodiesel which is made from vegetable oils and animal fats. Ethanol and Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as additive to gasoline and diesel respectively to improve emission. Biogas is a type of Biofuel produced by the biological breakdown in the absence of oxygen to convert gas from organic waste such as dead plant and animal material, animal feces, and kitchen waste including municipal solid waste.
There are may be very efficient nuclear fuel source of the future such as frozen Deuterium in laser driven nuclear fusion and Antimatter that are still at the development steps on the road to commercial use.
