Usually organic matter will begin to break down when it is exposed to warmth and oxygen but there are those products that are able to decompose using only the bacteria which is present within the matter. Biogas is then created and it is a truly unique source of energy. Carbon dioxide and methane are considered to be greenhouse gases, but they are rather wonderful, and safe, when they are burnt. The gas reacts with the oxygen and release a clean energy. One of the biggest threats to the energy available on the earth is its renewability. Most of the energy sources on the planet are not renewable and this is where biogas is such a wonderful option. Biogas is a renewable energy resource and as fast as it is used up it can be renewed. Biogas is often produced from sewerage and waste matter so technically we will only run out of the energy source if we stop producing such waste. This is of course unlikely so biogas can continue being produced. Biogas technology is used for heating and to produce electricity, and when it is taken further it can be used to create fuel for vehicles. It can be used to reduce the greenhouse effect by making use of the landfill gases rather than allowing the gases to rise into the atmosphere. Because it is so easy to set up a system for harvesting biogas, farms can especially benefit from having a biogas system set up. This is an especially wonderful thing to have on a farm as the waste from farm animals can be used to produce the biogas. An interesting fact to know is that the waste from a single cow is enough to power a light bulb for a day. Biogas is able to create work for hundreds of people especially in rural areas where electricity is mostly unattainable and jobs are just as scarce. A simple technology with some of the most important benefits towards renewable energy, biogas is the way of the future.
