What is the sustainability of coal mining?
Sustainability. By requiring coal mining, clean coal technologies are and always will be unsustainable. Coal is, by definition, a non-renewable resource and therefore cannot be replaced at anything close to the rate that it is being extracted, or would need to be extracted in an even more coal dependent United States.
Is coal good or bad for the environment?
There鈥檚 no doubt that coal is one of the most impactful energy sources of the last two centuries. For better or worse (and a lot of people would argue for worse), coal has provided billions with the energy to light up the planet. Without coal, the world would be a very different place today.
