Energy is the key word is always looking for every human beings in this world. Energy within the scope of breadth is the result of mankind's right to life becomes easier and much longer to be the caliph in this world. Coal is going salahsatunya between energy generated by the earth include petroleum, natural gas, geothermal, nuclear. When scarce and the price of oil began to soar, the world market will begin to look coal, would not be surprised if the coal was nicknamed The Black Gold.
Coal produced from plants that process coalifikasi remaining dead for millions of years. Sedimentary rocks that jet-black color will generate high heat when burned, is simply its almost like charcoal. The calorific value generated varies depending on the nature of the process coalifikasi coal. The more perfect the process coalifikasinya then usually the dihasilkanpun calorific value will be higher. The calorific value is what affects the price of coal, the higher the calorific value, the higher the sale price. In addition to its high heat so it is a good source of energy is also due to coal with high calorific value obtained is more rare than low-calorie coal. Caloric value in its formation is directly proportional to the age of the formation of coal geology or there are some cases that make coal a more instant to have a high calorific value.
Who feel the need for the Black Gold is machine power plants and industries that make the combustion process in its production. Each thereof has its own requirements of the calorific value and specific qualities that accompany coal so it is more economical and more effective utilization. For power plants need coal with high calorific value 6000 - 8000 cal while for other industries requiring coal with calorie range 4500 - 6000 cal.
Coal to be excellent when the world oil crisis so that the price of oil to be crazy. That's when the world market will begin to look for alternative energy other than petroleum and coal had to be excellent with IM. Coal used to produce energy that the human race with a lower price than petroleum, mining process is not as complex penambangannyapun petroleum. But it is precisely this which backfired in the human race itself.
Coal seam easily recognizable from the jet-black color so striking compared to other rock layers. No need technology that is too sophisticated to distinguish them so that way of uptake is also quite easy. This is the root of the problem when everyone feels able to menambangnya so that environmental aspects be ignored for the sake of a wad of money obtained easily. An example of this is very easily found in South Kalimantan. The people leaving in droves livelihood as a rubber tapper into impromptu coal miners with only with crowbars, hoes, sacks and knee. The more wealthy will hire ekscavator from the rental of the capitalist to tear apart the land contains coal in it. They clear land and create or open pits, tunnels and then collect the Black Gold into burlap sacks and then gathered again to be loaded into trucks that have been waiting patiently in the streets of the shaft. There is no environmental liability in this mining process. After being picked up the coal mining pits will be left open and the coal waste will contaminate the whole drainage basin. Coal contains sulfur value is higher then when in contact with water will produce H2SO4 or Sulfuric acid so that the water will be colored red and will kill the organisms that depend on it. Easily mining process is supported by coal price rise is also less specifically the apparatus to make miners more flourishing and breed.
Mbah Al Gore in filemnya Inconvinient Truth explains in a clear and frothy-foam on the bottom line of global warming that our planet is becoming more and more heat so that the collection of the polar ice began to melt and various other effects that threaten the survival of mankind. Well, the effect of offering the Black Gold is just not hamper the process of melting ice, but instead actually speed up the process in other words the use of coal is very supportive of global warming. It means support for our beloved geothermal add this. New coal will generate energy when burned and when the residue of combustion processes will produce smoke. Smoke is what brings high levels of CO gas and will be trapped in the atmosphere produces a greenhouse effect to take part rollicking make the earth hotter.
Currently, the axes of human life that depends on a lot of coal production, simpelnya example is the powerhouse for the surrounding areas of East Java and Suralaya and Paiton highly dependent on the coal supply and not from other power stations around the world plus the industry-industry. As long as oil prices soar still higher (not likely go down again), the utilization of alternative energy such as natural gas, geothermal, biodiesel is not maximized, coal would still be excellent. Roughly if made comparisons with statistical data muantep between gains and losses of coal utilization where a larger portion of it? Or even have contrived comparison ga kalo tau aja because the results will make my own horror and can not sleep in peace. The important thing is money well, so calm bobo
