Biomass (wood) power plant
The world is mostly run on fossil fuels (81%). Nuclear makes up 5%, with 14% from renewables. Solar panels and wind turbines contribute 0.8%.
When you hear 14% renewables, you will likely think ‘wow, things are going pretty well with the switch to renewables’. But these renewables are not the ones you hear about. The biggest contributor is humanity’s oldest fuel: wood.
4.91% is known as biomass as we also burn food (ethanol) and energy forest (trees or woody shrubs) in the rich world. This is, for instance, the American forests, cut down and shipped across the Atlantic to be burnt in European power plants to be called green and CO₂ neutral – of course, that is only true when the new woods have grown up in 50-100 years.
