Abstract:

By knowing energy carriers, human beings have made extensive efforts to extract and apply them in industry and economic development. These resources played an important role in the development of the industrial revolution, which led to the development of industry and technology, and global dependence on fossil fuels, especially oil, expanded rapidly in response to the need. With vast investments in alternative sources of renewable energy to address the crisis caused by the production and use of energy in terms of resource constraints and environmental threats, world life is affected by the need for energy and will be significantly dependent on fossil fuels in the future. The results of this paper indicate that use of oil and its derivatives is currently the first because of economic dependence of countries, and in the future, despite the constraints on resources, will play the most important role in global demand and supply.
