When doing energy comparison, fossil fuels like coal, gasoline and natural gas are still the most widely used sources of energy in the world today and the most limited and polluting. Coal is the most expensive of all sources of energy production as well as the most toxic to our environment. Burning coal in the mid-20th century caused a large part of the air pollution as well as the build-up of greenhouse gases on our planet. Gasoline is the 2nd most expensive source of energy used by human beings as well as another major pollution creating component used today. Natural gas is the next most expensive form of energy, though less polluting than coal and gasoline still emits toxic fumes into our air as well as can seep into our water systems. An example of this sort of pollution happened in the United States in 2008 when people were able to light their water on fire with a match. All of these fossil fuels are limited in supply, since it takes centuries to change organic matter into these fuels, eventually in the not too distant future we all know they will be exhausted.

Nuclear energy is safe, if handled properly as well as being a much less expensive, form of clean energy than fossil fuels. Nuclear energy costs 73% less than generic viagra pills coal, 66% less than natural gas and 63% less than lignite. There are two types of processes utilized today to produce electricity from the atom. Fission, or splitting the atom, creates less energy than fusion, or combining atoms. The only dilemma with nuclear energy is the possibility of accidents and the handling of toxic wastes.

Where renewable energy is concerned the most widely used in the 20th and 21st centuries has been hydro-electric, where electricity is produced by kinetic energy where the water flows naturally with gravity over blades called a turbine which connects to a generator to produce electricity.

Even though wind energy has been utilized on the plains of the United States for over a century to pump water for livestock, it is a relatively new source of electrical energy, for human consumption. Wind or air in motion contains the “kinetic energy”, which is converted into mechanical power by means of a wind turbine, very much like the hydroelectric energy is produced. The potential for wind energy is immense, and experts indicate wind power can furnish 20% of the world’s electricity. Since these statistics came from the turn of the 21st century, with the onslaught of new technology and research, the energy collected from the wind may be more efficient today.

Solar energy is one of the most important inexhaustible energy sources. As opposed to the established not renewable sources such as gasoline, Silagra coal, etc. solar energy is clean, inexhaustible and free. The main applications of photovoltaic (PV) systems are in either stand-alone (water pumping, domestic and street lighting, electric vehicles, military and space applications) [1] or grid-connected conformations (hybrid systems, power plants) [2].

Regrettably, PV generation systems have two major problems: the changeover efficiency in electric power generation is low, and the amount of electric power rendered by solar arrays varies endlessly with weather conditions.

All this in mind, energy comparison can play a good role in determining efficient and cost effective alternatives to the current energy sources.
