United States already generate 45 billion kilowatt-hours of electricity from biomass and that is 1.2% of whole United States electric sales.

United States also produce 4 billion gallons of ethanol, which is almost 2 percent of the liquid fuel used in cars and trucks. Same like that contribution for heat is also considerable. But still it can be produced more by better conversion technology and more attention paid to energy crops.

There are many benefits of biomass energy but an appropriate use is required for reaping these benefits. The benefits of Biomass Energy are given below:

Small Carbon Footprint

As compared to fossil fuel the carbon footprint of biomass energy is small which is one of the major benefit of biomass energy. When new plant material is available to replace the used material, no net carbon dioxide increase is produces by biomass energy. Bio power reduces fossil fuel consumption which also reduces the release of carbon dioxide, this seems to be a good news but there is a problem that fossil fuels are often used for manipulation and harvesting of biomass.

As it is suggested by the term, bio-fuels are fuels that are formed by the decomposition of biological matter.

Mostly the bio-fuels are derived from plants and they exist in all the three states of matter:solid, liquid, and gas.

Differences Between Bio-Fuels and Fossil Fuels

The differences between bio-fuels and fossil fuels are:

• Million years are required for fossil fuels to build whereas bio-fuels can be made extremely fast. They take just few days to build.
• Huge amounts of pollution are generated by fossil fuels. As compared to bio-fuels fossil fuels are comparatively safer.
• Unlike fossil fuels bio-fuels are renewable sources of energy.

Different Types of Bio-fuels

There are four types of bio-fuels:

1. First generation bio-fuels,
2. Second generation bio-fuels,
3. Third generation bio-fuels, and
4. Fourth generation bio-fuels.
