Since the emergence of the industrial revolution, the use of energy resources has increased considerably, particularly non renewable (coal, oil and gas), so these resources are no longer sufficient to cover the different energy needs, and this has become a challenge to the energy independance of many gouvernment now and in the future. This has caused the world to scramble for other ways to satisfy these needs in which the results of scientific research and development envolved from alternative uses of old energy sources and named green economy, and many think about the future of energy despite the barriers that still hinder the general application of this type of economy. Energy consumption in Algeria is focused almost entirely on fossil fuels, hydrocarbons, and gas in particular. In recent years, Algeria is deciding to move intro the green economy, the unique solution for meeting future energy requirements and helping reduce environmental risks.
