Very polluting.
Fossil FuelsFormed from the remains of living beings transformed in the underground by bacteria, pressure and heat.
OilComes from planktonAdv.: efficient, easy to extractDis.: Pollution during extraction, transformation and usageNatural GasComes from planktonSmall protozoa and algae that live in water bodies.Mostly methaneAdv.: Cleanest of threeDis.: toxic for humans, risk of accidentsCoalComes from woody fernsAdv.: cheapDis.: difficult extraction, highly pollutingOthersNuclearBased on unstable uranium isotopes.
