The process to convert solid biomass raw material to gas fuel or chemical feedstock gas (syngas) is known as Gasification. Chemical conversion of gas would be lavish and there are some microorganisms that can convert the CO, H(2), and CO(2) gas to fuels. The discovery of organisms which are capable of higher product yield, as metabolic engineering of microbial catalyst, will make this technology a feasible option for reducing our dependency on primary fuels. Different conversion methods are Gas Production, Pyrolysis , Anaerobic digestion, Bio refineries, Bioethanol production and sugar release from biomass. Production of energy crops could potentially compete for land with food cropping as a demand for biomass increases.

Bioenergy is conversion of biomass resources including agricultural and forest area residues, organic municipal waste and from vegetation to useful energy carriers inclusive of heat, power, electricity generation and transport fuels. Biomass uses is increasing day by day for modern applications such as Dendro-power, Co-generation and Combined Heat and Power generation (CHP). Relying on the useful resource availability and technical, economic and environmental impact, these can be the alternatives to fossil fuels applications. Bioenergy is a renewable energy resource mainly appropriate for electricity generation, heating & cooling in delivery, will be at the core of this sectorial shift in renewable power manufacturing and use and is becoming the dominant form of RES.

Plant material and animal waste as biomass is used to create transportation fuels and to generate electricity. Biomass energy is obtained from plant-based material and solar energy has been converted into organic matter. Biomass can be used in a variety of energy-conversion process to produce power, heat, steam, and fuel. Biomass is used by food processing industries, animal feed industry, and wood products industry, which includes construction and fibre products (paper and derivatives), along with chemical products made from those industries which have diverse applications together with detergents, biofertilizers, and erosion control products. The biggest opportunity for the global bioenergy technology is the increasing demand for electricity across the world.

Energy and environment are co-related in the technological and scientific aspects including energy conservation, and the interaction of energy forms and systems with the physical environment. The levels of atmospheric carbon dioxide has elevated by 31% among 1800 and 2000, going from 280 parts per million to 367 parts per million. Scientists see coming carbon dioxide levels to be as high as 970 parts per million by the year 2100. Different factors are responsible for this development, which include progress with respect to technical parameters of energy converters, in particular, improved efficiency; emissions characteristics and expanded lifetime. Various environmental policies have been implemented across the globe for reduction of GHG emissions for improvement of environment.

Solar panelS convert the sun's lightweight into usable alternative energy victimization with N-type and semiconductor device material. Once daylight is absorbed by these materials, the alternative energy knocks electrons to loose from their atoms, permitting the electrons to flow through the fabric and thus it provides electricity. This method of changing lightweight (photons) to electricity (voltage) is named the electrical phenomenon (PV) result , presently star panels convert most of the actinic radiation spectrum and regarding half the ultraviolet and actinic ray spectrum to usable alternative energy. Solar energy technologies use the sun's energy and light-weight to produce heat, light, hot water, electricity, and even cooling, for homes, businesses, and business.
