Difference between Fossil fuel and Bio mass
Fossil fuel
- The fuel in the form of wood, coal, crude oil which is obtained from mines or from earth’s crust is known as fossil fuel.
- Fossil fuel is non renewable form of energy.
- The work efficiency is moderately high due to which it is preferred in large scale application where large amount of energy is required.
- Fossil fuel is present in limited extent, so after certain year it will run out of stock.
- It produces the hazardous gases like carbon dioxide during burning which increase the air pollution in atmosphere.
- Release of gases like SO2 can cause acidic rainfall, produces green house gases which are responsible for global warming.
- Wastage left after burning is of no use.
Bio mass
- The fuel which can be generated from plant and animal products (waste) is known as Bio-Mass.
- Bio mass is renewable form of energy.
- The work efficiency is moderately low due to which it is preferred in small scale application where less amount of energy is required.
- It mainly consists of cow-dung, waste of animals, plant materials which left behind in harvesting the crops, vegetable waste allowed to decompose in the absence of oxygen to produce bio-gas.
- Bio-gas can be used as fuel for cooking instead of LPG.
- The bio- gas is 100 % safe and cost free mode of fuel.
- Slurry left behind contains nitrogen and phosphorus is used as fertilizers.
