Top Reasons Why Coal Is Bad (Problems With Using

2019-7-5  Lignite is fairly wet compared to hard coal when it is excavated, and it is often burned wet — it can be as much as 75% saturation in some varieties. This makes it inefficient to burn compared to if it was dried out which means using more fuel to get the same amount of energy, and more mining.
