Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste. When organic matter, such as food scraps and animal waste, break down in an anaerobic environment (absence of oxygen) they produce a mixture of gases, primarily methane and carbon dioxide.This gas is further used for cooking, Electricity Generation, BioCNG for Vehicles etc.
Solar energy is pure form of energy available from sun radiation. This abundant available natural energy is further harnessed using a range of ever-evolving technologies such as Solar Water heating, Photovoltaics, Solar thermal energy etc.
Rain water harvesting is simple, reliable and easily adoptable method for water conservation. There is rise in urban/rural water demands due to Natural imbalance & uncertainty of rainfall,dense population density etc. RWH is counter method to resolve water scarcity and flood issues.
