Biogas is one of the most common renewable energy resources. It can be produced by the anaerobic fermentation of wood or agricultural waste, on landfills or in sewage plants. These last two ways of producing biogas are the most interesting for cities in their policies of promoting renewable energies. The use of biogas is also interesting economically as it is in 1999, already one of the cheapest renewable energy sources. It often is burned in combined heat and power plants. J.S.C. Energy Investment Group has constructed first in Moldova Republic and first in post Soviet Union Cogeneration Station which will operate on biogas. Now Station is started on natural gas, but in 3 years will be transferred on biogas.
