What is Coal?
Electricity is the main use. Last year, 88% of all the coal used in the United States was for electricity production. Coal is no longer a major energy source for heating houses and other buildings.

How coal turns into electricity?
Coal is a fossil fuel used to produce around 40% of the world's electricity. It is created form the remains of plants that lived and died 100 to 400 million years ago when parts of the Earth were covered with huge swampy forests.
This is a movie about how coal turns into electricity:
Electricity is generated when coils are rotated quickly.
There 6 simple steps:
1. The coal or natural gas is first burned for mainly thermal (or heat) energy.
2. That thermal energy is used to boil water and to produce steam.
3. That steam is then forced through a high pressure tube called a steam line.
4. The steam then pushes a turbine.
5. That turbine then produces electrical energy.
6. The electrical energy is transported to your home and then it is used.

What's bad about burning coal?
Conclusion
Climate Change
If you use coal for filtering it helps the environment. Mineral carbon has properties that removes some toxic substances from the water, that is the reason why mineral carbon is widely used in filtering systems.
Burning coal to generate electricity produces greenhouse gases, which causes climate change. Just one 150 mega-watt coal-fired power plant can produce more than a million tonnes of green house gas emissions per year. That's about the same as 200,000 cars produce. Coal-fired power is the leading source of mercury emissions in North America, which are dangerous to people, fish and wildlife. Burning coal also produces large quantities of sulphur dioxide, nitrogen oxides and particulate matter.
