1. Biofuel Energy
Pros:
Made from different sources (ethanol, biodiesel, biomass, wood chips, municipal waste, among others)
Pollute less than fossil fuels during burning
Cheaper to produce than fossil fuels
Renewable energy source
Can be produced by any country
Cons:
Emissions include CO2, CO, and sulfur.
Biodiesel creates more nitrogen oxide than diesel from petroleum
Ashes from biofuels may contain harmful metals, such as cadmium and lead
A great amount of energy and water is necessary to grow crops, produce fertilizers and pesticides, and transform plants into biofuel.
Less efficient than fossil fuels
A great amount of the energy used to produce biofuels comes from fossil fuels
Although they have less carbon footprint, biofuels increase footprint through cultivation and harvest of crop, in addition to the destruction of forests for crop plantation
Currently, production costs are more than that of fossil fuel
