It looks like we may have peak fossil fuel demand quite soon, due to the ramp-up in renewable energies. But then again, it may be because of the overhang in debt is killing demand, at least for finished products.
And last year the demand for coal dropped quite a bit. It's probable that the drop in coal demand was because of drop in demand from China for commodities: its economy has been faltering a bit lately. But the drop in coal demand was made up for, and a little bit more, by demand for oil and natural gas. All in all, fossil fuel use rose by 0.56% yoy in 2015.
