Hydrogen EnergyHydrogen is the most abundant element available on earth but it is rarely alone. Even water contains two third of hydrogen. It is usually available with other elements and have to separated before we can make use of it. Hydrogen has tremendous potential and can be used to power up homes, vehicles and even space rockets. It takes a lot of energy to separate hydrogen from other elements and therefore it proves toquite expensive to extract it. Take a close look at hydrogen energy and see how it works.The main beneft of hydrogen energy is that it is clean source of fuel and does not leave any waste elements behind except water. There are no harmful emissions and is environment friendly. It is completely renewable and can be produced over and over again on demand. Hydrogen can also be used to make bombs like the ones used by America on Hiroshima and Nagasaki which makes it highly infammable. Dependency on fossil fuels still remains as we need them to extract hydrogen from other elements. Also, it is quite expensive to produce and store.These are some of the alternative energy sources that can be taken into consideration when planning your energy production and usage. You can harness any of these and you will satisfy your power needsAlternative Forms of Energy / HydrogrenAs many of you may know, hydrogen comes from water (which is two-thirds hydrogen and one-third oxygen). Electric current is passed through water to separate hydrogen from oxygen. The resulting gas, Hydrogen, is then stored in pressuried tanks.Hydrogen Alternati!e Energy has shown promising results recently.And it has "een particularly successful in the car industry.#n these cars, the fuel cell system is used which con!erts hydrogen into electricity. Hydrogen as fuel is eco-friendly and much more safe than gasoline.Hydrogen EnergyHydrogen is the most common element on earth as it is available with water and 70% of the earth is covered with water. Once hydrogen is separated from water, it can be used to generate electricity. Hydrogen is completely renewable as it is extracted from water and is available in abundant supply.Hydrogen energy, when burnt does not leave any toxic gases in the atmosphere. The downside of using this alternate source of energy is that the technology is still in its early stage and it will take a long time before it can be used on a wide scale.What is Alternative Energy? Alternati!e energy is power that comes from sources which are not goingto run out, do not pollute as much as fossil fuels (oil, coal, natural gas), or do not create lefto!er materialsthat are harmful to people and the en!ironment.The term, $alternati!e,$ in a sense,is meant to contrast en!ironment friendly energyagainst formsofenergy that hurt the en!ironment (coalpower, naturalgas, and oilpower). %ther names for alternati!eenergy include clean energy, green energy and renewa"le energy.Alternative energy fuels can help reduce harmful greenhouse gas emissions produced from traditionalgasolineor diesel fuels. &singalternati!eenergyfuelsmeansthat youmight ha!etochangeyourcon!entional !ehicle in for a more en!ironmentally-friendly ride. #s this true' (et)s find out.Alternative Energy Fuels - Battery-electric VehiclesAlternative Energy Fuels - Hybrid-electric VehiclesAlternative Energy Fuels - Fuel Cells and Hydrogen#f you are using a porta"le or a stationary power de!ice, then fuel cells might "e the ideal option for you.Electricity is generated in fuelcells electrochemically when hydrogenandoxygen arecom"ined. *uel+ells can produce ero or !ery low emissions depending on the source of the hydrogen.
