See how they don't use any heavy fuel oil anymore? They switched to biofuels. Chopped down all their forests.

The massive production of charcoal (at its height employing hundreds of thousands, mainly in Alpine and neighbouring forests) was a major cause of deforestation, especially in Central Europe. In England, many woods were managed as coppices, which were cut and regrew cyclically, so that a steady supply of charcoal would be available (in principle) forever; complaints (as early as in Stuart England) about shortages may relate to the results of temporary over-exploitation or the impossibility of increasing production. The increasing scarcity of easily harvested wood was a major factor for the switch to the fossil fuel equivalents, mainly coal and brown coal for industrial use.
