ABSTRACT
Biomass energy is a term that includes all energy materials derived from biological sources, including wood wastes, agricultural residues, food industry wastes, sewage, municipal solid waste, and dedicated herbaceous or woody energy crops. Wave energy is produced when electricity generators are placed on the surface of the ocean. The fraction of solar radiation that is reflected back into space is known as the albedo of the atmosphere. Solar radiation available at a particular location keeps changing both on a daily basis as well as annually. Hence the amount of solar radiation keeps fluctuating at any given time interval depending on the position of the sun and the location of the site. The three main cases of solar radiation depending on the position of the sun can be categorized with the help of the Solstices. The systems which are available commercially are described below: As the name implies, these systems are not connected to electricity grid.
