Abstract

As fossil fuels are depleted, renewable energy as an alternative for the replacement of fossil fuel is extensively considered. The new trend for developed countries would behave well as independent to fossil oil resources. In European Countries, highly developed and purified biofuel/biogas is the mostly used as a suitable fossil fuel replacement in city transportation sectors. Renewable energies became more popular in China and United States, having great number of plants for generation of heat and domestic power sources. In this article different renewable energy sources were reviewed and potential sources were identified. Renewable energies could be categorized based on the origin of their resources. Main potential sources of renewable energies would be solar energy which is benefited from sunlight radiation. Another potential renewable source would be wind power, ocean thermal, sea waves, biomass and etc. In fact, some of the renewable energy resources are dominated based on availability of renewable energies. Renewable energies from biomass are one of the main sectors which are very attractive for government agencies. These sources of energy are used for many years for instance use of biogas in China and India or burning biomass for providing heat sources. Present review paper focused on processes of renewable energies from biological sources for production of biohydrogen, bioethanol and biogas as suitable and alternative fuel.
