Coal is a mineral of fossilized carbon, that mean is a sedimentary rock.
In fact is the result of fossilized pet and plant matter. What's coal?? History of coal The coal reserve is estimated by 2 international institution.
The first is the German Federal Institute for Geo sciences an Natural Resources (BGR). The second is the World Energy Council (WEC). Coal reserves Coal is cheapest material

Coal is also abundant; all of the continents have coal resources.

Coal is dominant because of his "power density". . Economic aspect of coal In the present, coal still represents the most significant source of electricity in the world; with dwindling reserves of oil and gas its share is likely to be even higher.





Therefore, attention is being paid to development of more efficient and cleaner methods of coal combustion and its conversion to electricity. Energy resources it's a resource that we burn or use the natural power to get energy. Some energy resources are unlimited, we can
use it without effect the rest of the energy or ecosystem,and other is quantifiable, we can evaluate the storage. Advantages:
relatively cheap,
large deposits left that
easy to obtain, some coal being close to the surface.
easy to transport
it's a solid. Disadvantages:
deep below the ground
dificult, costly and dangerous to mine. The coal reserve is enough for 112 year at the current rates of production. In comparison the oil reserves are around 46 years and the Gas reserve around 54 years. That's why coal still to be very important energy sources for the future. Why coal is so important energy? Coal is primarily used as a solid fuel to produce electricity and heat through combustion.

China is the largest consumer and producer of coal.

Coal represents 70% of the energy needs of China.

46% of total power generated in the USA was done using coal.

Limit the escalation of oil prices. The major coal exporters are Australia, Indonesia and Russia.
In 2003 Australia has exported 238.1 million short tons. In 2010 she has exported 328.1 million short tons.

Indonesia has exported 107.8 million short tons in 2003 and 316.2 million short tons in 2010.

Russia increases also his coal export from 41 million short tons in 2003 to 122.1 million short tons in 2010. The major coal importers in 2010 are:
Japan with 206.7 million short tons
China, with 195.1 million short tons of coal
South Korea, with 125.8 million short tons of coal Future forecasts: Kyoto protocol and coal In the future the governments are expected to close illegal and dangerous mines:
to create attractive conditions for private sector investments,
to place emissions from coal in a more balanced perspective,
to encourage efficient and clean use of coal and also to support the Research and Development on carbon sequestration.

But it is necessary to help the new developing country to develop modern, safety and clean coal technology. Acceptability: The most specialist project that, the competitiveness of the coal price will grow till 2030.
The main competitors from coal in the future will be the natural gas and perhaps the new nuclear technology. The idea of technologies that improve the ‘efficiency’ of coal-fired power stations is something that is often derided Using these efficient technologies does make a significant difference in reducing emissions from coal-fired power plants. “Fossil fuels will be part of the energy mix for many years to come.

Arguing that developing countries shouldn’t use coal and shouldn’t get any form of support, such as through the CDM, to actually clean up their coal burn is not helpful – either to the sustainable development of these countries, or to the global response to climate change. The sustainability of coal’s contribution is gauged against tree benchmarks.

The availability to make demand, the accessibility for customers and the acceptability and computability with societal concern. Accessibility: With the Fuel economic development in developing country, coal covers 33% of primary energy demand and 53% of electricity generation till 2030.

To abate local and regional pollution and also mitigates climate changes. The clean coal energy (EU) expects to reach 72% of the coal based electricity till 2030. The coal and associated industries are expected to replicate good health and safety standards, to facilitate the transfer of technology, to apply clean coal technologies actively, to assist community development and to build national awareness campaigns. New methods utilization of coal:
coal gasification
modern liquid fuels form coal
the future of coal concerning production of electricity
removing of carbon dioxide from combustion gases
new materials Thank you;)
