What Are The Benefits Of Coal To Our Life

As global demand for energy continues to rise - especially in rapidly industrializing and developing economies - energy security concerns become ever more important.To provide solid economic growth and to maintain levels of economic performance, energy must be readily available, affordable and able to provide a reliable source of power without vulnerability to long- or short-term disruptions.Interruption of energy supplies can cause major financial losses and create havoc in economic centers, as well as potential damage to the health and wellbeing of the population.The forecast growth in energy demand means that we will need many sources of energy now and into the future.A diverse mix of energy sources, each with different advantages, provides security to an energy system by allowing flexibility in meeting each country's needs.Coal has an important role to play in meeting the demand for a secure energy supply.Coal is abundant and widespread.It is present in almost every country in the world with commercial mining taking place in over 50.Coal is the most abundant and economical of fossil fuels.At current production levels coal will be available for at least the next 118 years - compared to 46 years for oil and 59 years for gas.Indigenous coal resources enable economic development and can be transformed to guard against import dependence and price shocks.Coal is also readily available from a wide variety of sources in a well-supplied worldwide market.It can be transported to demand centres quickly, safely and easily by ship and rail.A large number of suppliers are active in the international coal market, ensuring competitive behaviour and efficient functioning.Coal can also be easily stored at power stations and stocks can be drawn on in emergencies.Unlike gaseous, liquid or intermittent renewable sources, coal can be stockpiled at the power station and stocks drawn on to meet demand.Coal is also an affordable source of energy.Coal prices have historically been lower and more stable than oil and gas prices and it is likely to remain the most affordable fuel for power generation in many developed and industrialising countries for several decades.Coal-based electricity is well-established and highly reliable with the application of dryer machine.Over 41% of global electricity is currently based on coal.The generation technologies are well-established and technical capacity and human expertise is widespread.Ongoing research activities ensure that this capacity is continually being improved and expanded, facilitating innovation in energy efficiency and environment performance.Coal can also be used as an alternative to oil after processed by impact crusher.The development of a coal to liquids industry can serve to hedge against oil-related energy security risks.Using domestic coal reserves, or accessing the relatively stable international coal market, can allow countries to minimise their exposure to oil price volatility while providing the liquid fuels needed for economic growth.Dryer machine:http://www.Hx-crusher.Com/dryer_machine.Html impact crusher:http://www.Hxjqchina.Com/product-list_12.Htmldryer machine:http://www.Hxjq-crusher.Com/21.Html.
