methane major component of fossil fuel, natural gas. can produced biological product in digestion, , anaerobic action of microbes on biomass (as in biodigester.)

part of natural gas, methane used predominately cooking , heating fuel. possible adjust internal combustion engine accept natural gas (often in compressed form: cng) motor fuel similar way propane used (forklifts...)

however, "eco-friendlyness" of fossil fuel relative. methane greenhouse gas several times more potent carbon dioxide. (although tends remain in atmosphere 6 years.)

recovering natural gas uses criticized practice of hydro-fracking. issues of hydrofracking mentioned include increased earthquakes, pollution of ground water, excessive use of fresh water supplies , no present plan disposal of millions of gallons of water polluted chemicals , radioactivity being used medium hydrofracking. claims fuel "non-polluting" mistaken. can claimed may better alternatives.

it eco-friendly, non-polluting. works
