Energy is an important necessity for the continuity of human life. While energy contributes to human life, it can also harm the environment and human health. The method of obtaining energy, inputs and outputs in production are the most important elements. As an environment and human friendly alternative energy, biogas is the product of the digestion of organic materials under anaerobic conditions. On the whole, electricity produced from biogas generates much less carbon dioxide than conventional energy. Shortly, Biogas is a carbon neutral way of energy supply. Turkey's energy demand has increased over the years and Turkey's importance in world energy market has been growing both as a regional energy transit hub and as a consumer. The increasing energy consumption of Turkey makes it dependent on foreign sources year after year. Renewable energy projects have been attractive for a few years as Turkey aims to reduce its dependence on external sources. Today, Turkey has high biogas potential and infrastructure that will provide enough input for biogas production and energy generation. Raw materials are mainly procured from animal livestock (e.g. manure from cattle or manure from poultry) agricultural areas (e.g. straw of cereals, sugar beet leaf or tomato waste) and residues from food, fruits and vegetables (e.g. press cake of sugar beet, olive press cake). Because it is a very useful and economic energy in terms of the use of organic wastes Biogas is preferred in terms of clean energy alternatives. Turkey is one of the livestock and agricultural zone in the world therefore has a large biogas potential more than European Countries. Today, Turkey has the potential of 2000 biogas plants which will operate in animal waste. According to official information biogas in Turkey, convertible biomass weight is 117 million tons/year. This study describes the situation and the importance of energy production via biogas in Turkey, an agricultural country. The current status of bio-energy and requirements in biogas production which plays important and vital role for human life and the environment, has been examined.
