Energy & capability Essay Example for Free

thrust capability EssayEnergy has been defined as the capability to produce an effect, it back tooth be stored within a system and can be transferred from one system to another and use it in our everyday life. Gener every last(predicate)y, countries around the world benefited most their naught consumption from anoint. Unfortunately, oil crisis affects every nation since producers and sellers monopolize its price as well as its production barely apparent drawbacks are expected due to depletion of oil reserves and environmental pollution.The join States merely consumes one-fifth of the worlds oil produced and 35% of it utilize for transportation hence oil importation ought to resolve through alternative elan vital utilization. It is good to hear that researches and new technologies of alternative energy production and usage have been recently prioritized by the government. Theres only one way of life to insulate the US from the corrosive power of oil, and thats to develo p an alternative energy resource thats readily lendable domestically henry . total heat is the simplest, most abundant element and it is lighter than nisus and can be found in the atmosphere in an insoluble substance gas. It is only available on earth in a compound state like water supply (H2O), coal, petroleum and methane (CH4). It has the highest energy content of any common arouse by weight (about three times more than gasoline), but the lowest energy content by volume (about four times less than gasoline), an energy newsboy and derivative of other chemicals that can be produced from a variety of resources (water, fossil displaces, biomass) .Hydrogen can be extracted with no environmental pollution effects through steam reforming in which natural gas reacts chemically with steam to produce hydrogen and CO2, electrolysis which splits water into hydrogen and oxygen and the latest discoveries from cultured microbes that emits hydrogen , all require expensive financial support from the government.The send away carrel is an electrochemical devise that can interminably convert chemical energy into electrical energy of power as long as give the sack and a reactant are supplied hence chemical reaction of hydrogen and oxygen in a fuel cell create electricity leaving only water as byproduct unlike inborn combustion engines that also generate carbon monoxides hazardous to man and environment as well. Hydrogen a good deal described as the perfect fuel for it does not explode, environment-friendly exploitation and exhaustible major reserve of water will never run out of hydrogen however, considerable amount of energy is needed for tranquillise production of hydrogen.The higher temperature fuel cells can reform natural gas for instance, gaseous hydrogen must(prenominal) be compressed and stored in tolerable high pressure tank to hold enough fuel for travel while liquid hydrogen demands more than -4000F for refrigeration both require high temperatures for f uel to recuperate. Adoption of hydrogen technology should settle first the hydrogen fuel-tank problem, mass production of fuel cell vehicles, alter fueling infrastructure to hydrogen, intensify hydrogen production and public campaign to sell the hydrogen economy .Indeed, importation of fuels can be minimized plus pollution free environment then upsurge economic growth.
