Biogas - Wikipedia

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.Biogas is a renewable energy source.. Biogas is produced by anaerobic digestion

Concentrating Solar Power: Energy from Mirrors

ing solar power systems generate electric-ity with heat. Concentrating solar collectors use mirrors and lenses to con-centrate and focus sunlight onto a thermal receiver, similar to a boiler tube. The receiver absorbs and converts sun-light into heat. The heat is then transported to a steam generator or engine where it is converted into
