Biomass Biomass is organic material made from plants and animals. Biomass is a renewable resource. When it is burned chemical energy is released as heat. Biomass if found all around the world. It is most commonly found in rainforests.
History of Biomass Biomass was discovered when humans started using fire. Up until the 1860’s the United States used biomass for 91% of all energy consumption in the form of wood.
Where do we get Biomass? Biomass if found all around the world. It is commonly found in rainforests. Biomass is mostly found it waste such as dead trees, tree branches, yard clippings, left-over crops, wood chips and other stuff. Biomass is used for duel applications such as heat and power generation.
How is Biomass stored and released? Plants store the carbon dioxide when they grow. When it decomposes, it releases the CO2. When we replant the plants it ensures that the CO2 Biomass contains stored energy from the sun.
Forms of Biomass http://dsc.discovery.com/videos/how-stuff-works- ethanol.html http://dsc.discovery.com/videos/how-stuff-works- ethanol.html This video shows how corn is used for biomass.
Advantages of Biomass Advantages: It can be used in place of fossil fuels for power production. It can reduce greenhouse gas emissions and dependence on foreign oils. It does not add CO2 as it absorbed carbon as it releases when consumed with fuel. By using biomass is can reduce the need for Earth’s other important resources.
Disadvantages of Biomass Collecting enough materials to make fuel can be difficult. Although it is a little bit, Biomass still creates greenhouse gasses. Certain materials needed to create biomass can be hard to get. It takes more energy to plant, cultivate and harvest the crops and trees than it does to get a net energy gain
How it is Used Today Around the world, more than 2.5 billion people rely on biomass such as wood, crop residues, dung, and other fuels for heating and cooking. Most of the energy consumption of biomass today is wood and charcoal. Biomass energy can be used for heating, cooking, and generating electricity.
