The production of biogas is sustainable, renewable, carbon neutral and reduces the dependency from imported fossil fuels. Often operators or beneficiaries of biogas plants are able to become fully energy self sufficient. They produce the heat and eletricity they consume.
The use of biogas supports the objectives of the European Union of 20 % of renewable energy by 2020. Biogas is a carbon neutral way of energy supply. The substrates from plants and animals only emit the carbon dioxide they have accumulated during their life cycle and which they would have emitted also without the energetic utilization. On the whole, electricity produced from biogas generates much less carbon dioxide than conventional energy. 1 kW of electricity produced by biogas prevents 7,000 kg CO2 per year.
