The renewable fuels I’m thinking of are bio diesel and ethanol, not wind or solar.
In: Chemistry
When you burn fossil fuels you are reintroducing carbon long removed from the environment. We evolved in this lower carbon environment and Earth has adapted to it. By reintroducing it, you increase the amount of carbon, vs Biofuels which just burn the carbon that currently exists in the environment.
Worth adding that biofuels aren’t “clean”. Just significantly less problematic.
Edit: To clarify a bit. The existing carbon wouldn’t always naturally get added to the atmosphere. The carbon in a plant might be consumed by an animal and added to that animal. I’m just keeping it simple.
