Biofuels and Alternative Energy

Biofuels are those which are derived from newly dead or living plant material and animal waste. The frequently used biofuels are ethanol and biodiesel. Biofuels are divided into four “generations,” or categories based on the raw materials used to produce them. They are:

·         First generation - food related sources

·         Second generation - non-food sources

·         Third generation - algae

·         Fourth generation – other sources

Some energy sources, such as sun and wind are considered sustainable because   they are renewable. Biofuels are also considered renewable because you can grow biomass feedstock again and again to produce biofuels continuously. The biofuels is considered as one of best source of alternate energy to overcome the future energy demand. Alternate energy is the best option with respect to the environmental pollution.
