Each cubic meter (m 3) of biogas contains the equivalent of 6 kWh of calorific energy. However, when we convert biogas to electricity, in a biogas powered electric generator, we get about 2 kWh of useable electricity, the rest turns into heat which can also be used for heating applications. 2 kWh is enough energy to power a 100 W light bulb for 20 hours or a 2000W hair dryer for 1 hour.

These gases, called biogases, can then be used in various applications. Biogas is sometimes called deep green energy because it is such a valuable source of energy in rural areas. It provides a clean, easily-controlled source of renewable energy and requires very little labor, replacing firewood or fossil fuels. What Is Biogas Made Of?
