coal and technology
Really and truly, coal and oil aren't being created fast enough for human use. Coal is most likely not to be used that often; since not everyone is burning coal, we have plenty of it. Oil is a different story. Since we use oil, sometimes in our daily lives, it has to be produced more often the coal, because me use it so much!
The steam engine needs coal, the coal comes from the coal mine
It is very important to use clean coal technology. The pollutants from burning coal causes health problems as well as environmental problems. The clean coal technology cuts back on these pollutants and provides a cheap form of energy.
Using coal to generate electricity. (APEX)
No, coal is not environmentally friendly. Gathering it requires mining with machinery and burning coal produces many pollutants. Eventually, coal will run out. Solar energy is a good alternative since it is free and will not run out.

When you burn coal you are using it not altering it.
Damage to the lungs from coal dust. Entrapment or death from cave-ins.
Yes. Cars do for gas
Because coal is a non-renewable fossil fuel that will run out someday.

-crushing the coal into small chunks and washing out the sulfur dioxide. -burn the coal, reducing the NOx. this is called 'staged combustion'. -using a 'fluidized bed boiler', realising the sulfur dioxide, then the limestone captures the sulfur and changes it into calcium sulfate. hope this helps...its just a rough draft of how clean coal tech can be done though.
