Fossil fuels like gasoline and coal were once the primary source of energy everywhere. However due to soaring costs, shrinking reserves, and the harmful effect of fossil fuels on the atmosphere, other sources of environment friendly energy producers are being looked into.
Biofuels or fuels from biomass can be described as “solid, liquid or gaseous fuel obtained from biological matter and fossil fuels.” They consist of plant and animal waste which when decomposed is converted to energy. Therefore it is nothing but recycling of organic waste. It is inexpensive, does not pollute the environment, and reduces global warming. Biofuels can be produced from plants and their derivatives, and used to run automobiles, in cooking, and heating homes. Methane from animal waste, wood and wood shavings, landfill gas from decomposition of organic waste, and ethanol from plants are termed biofuels.
