Many people wonder what clean fuel means. Essentially, clean fuel is fuel that does not produce C02 or green house emissions. Many vehicles are beginning to transition into clean fuel propulsion. Hybrids, EVs, and hydrogen are just some. As more and more fuels are sought after in hopes of establishing a clear clean fuel alternative, there continues to be a debate on the parameters used to denote an authentic clean fuel. This debate has affected fuels like biodiesel and ethanol and as more research indicates, they are in fact not clean fuels do to pollutants found in them.
