Abstract: Publisher Summary Energy can be simply described as a dynamic indicator that shows the development level of a country. There is a strong positive correlation between energy production/consumption and economic development/scientific progress. Energy demand is increasing at an exponential rate due to the exponential growth of the world population. Global energy demand is expected continue to grow steadily, as it has over the last two decades. According to an investigation, with current consumption trends, the reserves-to-production (R/P) ratio of world proven reserves of coal is higher than that of world proven reserves of oil and gas–155 years versus 40 and 65 years respectively. Despite environmental issues and competitive pressure from other fuels, coal is expected to maintain a major share of the world's future energy use. In recent years, concerns have been growing worldwide regarding the environmental consequences of heavy dependence on fossil fuels, particularly climate change. Coal is undoubtedly part of the greenhouse problem. The main emissions from coal combustion are sulfur dioxide, nitrogen oxides, particulates, carbon dioxide, and mercury. The introduction of cleaner coal technologies can reduce the environmental impact of the increase in coal use. During the last two decades, significant advances have been made in the reduction of emissions from coal-fired power plants. In short, greenhouse gas reduction policies have and will have a major impact on the future use of coal.
