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.
U.S. Bioenergy Statistics Society has just begun to tap new renewable sources of energy from agriculture and forestlands on a commercial scale that impacts energy markets. Among these sources are biofuels, a small but important component of current fuel consumption in the U.S. transport sector. In 2012, biofuels accounted for roughly 7.1 percent of total transport fuel consumption, or 13.8 billion gallons, unchanged from the previous year. Ethanol, made mostly from corn starch from kernels, is by far the most significant biofuel in the United States, accounting for 94 percent of all biofuel production in 2012. Most of the remainder is biodiesel, which is made from vegetable oils (chiefly soy oil) as well as animal fats, waste oils, and greases.
