Energy, we all need it to do a
work. As humans we use energy stored in our body. But most of the time energy
stored in our body is not sufficient enough to finish the required work.
Therefore we use machines to do our work. Most of these machines driven by
electricity which makes electricity to play a major role in the form of energy for
development of a country. Electricity generation required an efficient energy
source. Energy sources that we use today is limited resulting a global problem called
energy crisis.s
Hydro power is the most common
energy source that people familiar with the electricity generation in Sri Lanka.
Other than that developed countries use nuclear energy to generate electricity.
Fossil fuels, geothermal energy is also using for electricity generation. Due
to the modern climatic changes hydro power stations cannot operate at their
maximum capacity. And Nuclear power plants need more advanced technology and
more capital which cannot afford by developing country like Sri Lanka, which
lead to find a convenient alternative energy source to generate electricity. Such
convenient alternative energy source is Coal. Coal is a solid fossil fuel which
containing Carbon and it is the most impure of fuels, its impurities range from
trace quantities of many metals including uranium and thorium to much larger
quantities of aluminum and Iron to still larger quantities of impurities of
such as Sulfur.
