Biomass belongs to renewable energy sources and refers to different biological material that has its origin in plants and animals. The most widely used source of biomass is wood but biomass has a variety of different other sources such as waste and alcohol fuels.
Biomass is a renewable source of energy and therefore is being constantly replenished because plants can be re-grown time and time again.
Biomass improves our energy independence and our energy security by decreasing the need for expensive foreign oil import.
Increased biomass production from waste could give us a very interesting and useful waste disposing opportunity.
Biomass emits significantly less greenhouse gases than currently dominant fossil fuels.
Biomass sources are available in all parts of the world and can give instant results.
Large number of conversion methods can be used to convert biomass into useful form of energy.
High dependence on wood could lead to deforestation that would contribute to climate change because our trees are important carbon sinkers.
Biomass isn't 100% emission free energy source, and it's therefore not as environmentally friendly as some other renewable energy sources like sun and wind. Burning wood can lead to big increase in greenhouse gas emissions.
The competition with food crops for the land which could lead to higher food prices and more hungry people in the world.
Science is still looking for cheap and efficient biomass production technologies.
Often connected with large land requirements.
