it includes biofuels, biomass, and biogas

1. India is a land of villages where the
energy required for domestic
purpose such as cooking is met
from dried woods, twigs and leaves
of plants and other dried organic
matter such as cow dung.
This organic matter called as
biomass is available freely as waste.

2. What is Biomass?
 It is renewable energy source because it is available
freely as waste and discarded matter.
 It is a sustainable fuel which can reduce the net carbon
emissions when compared with fossil fuels.
 It includes matters like grass, leaves, wood chips, rice
husks, sugarcane fiber etc.

4. Advantages
 Biomass can make electricity and heat (can replace
fossil fuels).
 Cheaper than fossil fuels.
 According to a study, there are 66,000 jobs supported
by Biomass.
 Rural development and income opportunities.
 Biomass is available everywhere so no need of any
transportation.
 Don’t pollute enviroment.

5. Disadvantages
 Biomass collection is difficult and expensive.
 Calorific value of biomass is very low.
 Biomass contain 50%-90% water and it is heavy, If
transportation is needed it becomes very difficult.
 Direct combustion of biomass produces smoke
and smell.
 Biomass plants occupy large land and areas.

8. Biogas
 Biogas typically refers to a mixture of
different gases produced by the breakdown of organic
matter in the absence of oxygen.

9. Utilization
 Cooking
 Lighting
 Power generation
 Transport fuel

10. Benefits
 Reduces global warming.
 Reduces deforestation.
 Produces good quality manure for increasing soil
fertility.

11. Disadvantages
 Less economic.
 Need a large area.
 Difficult to enhance the efficiency of a biogas system.

13. What is a bio fuel?
 Any hydrocarbon fuel that is produced from organic
matter (living or once living material) in a short period
of time (days, weeks, or even months) is considered a
Bio fuel.

14. Types of Bio Fuels
Bio fuels are often broken into two categories
 First generation biofuels, also known as conventional
bio fuels
 Second generation biofuels, also known as advanced
bio fuels.

15. Positives of Biofuels
 Fossil fuels are exhaustible,
 Biofuels can be used as a alternative,
 Biodegradable,
 Biofuels produe less pollution,
 Sulphur free,
 Reasonable calorific value.
