Write a short note.

Bio-fuels

Answer 1

1. Plants produce biomass by the process of photosynthesis in which solar energy is used to prepare carbohydrates and oxygen.
2. Biomass includes forest residues, crop residues, etc.
3. For production of biofuel, biomass is harvested and transported for threshing. The residue left after threshing contains cellulose, which is later on converted to glucose.
4. The glucose is then converted to liquid fuel through fermentation, which is used for different purposes.
5. Biofuels are renewable sources of energy.
6. They are available in solid (dung, crop residue), liquid (vegetable oils, alcohol) and gaseous (gobar gas) forms.
7. Biofuels are easily available in sufficient amounts.
8. They are reliable fuels of the future.
