What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
waste. Because they are artificial, they has about 10-15 percent higher methane (CH4) content than normal landfill gas.
Amount of organic waste is approximately 8,300tons/year by 2008 and 2007, among which only about 7% (6.1million tons/year) are used to source of energy (biogas).
Bio-gas produced by using organic waste were used mostly as a heating fuel of the dige

Do not use expansive catalyst
Do not need reforming
Do not need electrolyte supplement
Price is cheaper than others
Technical characteristic

variety form and high efficiency are possible because components are solid
1.1 New Renewable Energy
New Renewable Energy= new energy+ Renewable Energy
New energy : future energy
Renewable energy: almost indefinitely energy
condition
1 Replace petroleum
2 Carbon emits less than petroleum.
3 Sustainable energy can be used without depletion
