Ethanol fuel. The use of ethanol as a fuel for internal combustion engines, either alone or in combination with other fuels, has been given much attention mostly because of its possible environmental and long-term economical advantages over fossil fuel. Ethanol fuel is an alternative to gasoline.
Methane is then purified and used as an energy source to produce heat (thermal energy) or electricity. Fermentation is adding bacteria to biomass and produce ethanol (an alcohol). We can use 10 percent ethanol made from corn and added to gasoline to run our cars.
