The decreasing carbon to hydrogen ratio in fuel. From prehistoric ages, about 750,000 years ago, until the beginning of the 19th century, wood was the main source of energy. Since society has moved from wood, to coal, to oil to natural gas, to – soon- pure hydrogen. Wood has 10 atoms carbons for 1 atom of hydrogen. Coal, 1~2 Carbon for 1 hydrogen Oil, 1 carbon for 2 hydrogen Natural Gas, 1 carbon for 4 hydrogen. Burning Carbon produces CO2 a Green House Gas. Burning Hydrogen produces water. Together with energy conservation, Decarbonization of our economy is a sustainable solution to Climate Change.
