What are alternative source of energy?
In an age of increasing fossil fuel prices, uncertainty of energy supplies and concern over the effect of rising carbon dioxide levels in the atmosphere, the role of hydrogen fuel as an alternative energy source is being reexamined. Plentiful Supply of Hydrogen Hydrogen is the most common element in the universe. David L. Heiserman, in his Exploring Chemical Elements and their Compounds, published by TAB Books in 1992, lists hydrogen as the most common element in the universe. On Earth, according to Basic Research Needs for the Hydrogen Economy. published by Argonne National Laboratory, U.S. Department of Energy, in May 2003, hydrogen is the third most abundant element. However this hydrogen does not exist as the pure element, but as part of other compounds, mainly water and fossil fuels. Hydrogen is Not a Source of Energy Commercially, hydrogen is mainly produced from fossil fuel and to a lesser extent by electrolysis using energy produced from fossil fuels. Basic Research Needs for t
