How much energy is in biogas?

Each cubic meter (m³) 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.
