It contains LOTS of energy that you can release simply by setting the coal on fire, yet it's

stable enough that you can store it loose in a box, unlike nearly every other major

Plus, it's one of the most abundant and widely distributed fuels; in lots of places

you can basically just start shoveling and boom!

Because of these great properties, we started using coal thousands of years ago to stay

warm and cook, and more recently, to fuel the ironworks, steam engines, and electricity

of the Industrial Revolution, which led to, y'know, the modern world.

Today, coal still supplies more electricity than any other source, and there are underground

reserves that could power humanity for over 100 years.

But for as long as coal has been awesome, coal has also been the worst.

Mining coal has led to accidents and diseases that kill coal miners, and burning coal has

coated our cities, homes and lungs with layers of soot and poisonous chemicals, and left

If we must use coal, we can mine it without humans, and we can try to bury the pollution

But we also no longer need to use coal at all; we now have alternatives like wind and

solar and hydro and nuclear, which are way safer than coal, way better for the climate,

It may take a while before we can fully replace the energy source that made and still powers

the modern world, but it's high time we try to go coal turkey.
