Most experts predict we will exhaust easily accessible reserves within 50 years,though opinions and estimates vary.We could fast reach an energy crisis in the next few decades,when demand exceeds supply. As conventional reserves become more difficuh to access.others such as oil shales and tar sands may be used instead.Petrol could also be obtained from coal.
Since we started using fossil fuels,we have released 400 billion tonnes2 of carbon,and burning the entire reserves could eventually raise world temperatures by 13℃.Among other horrors,this would result in the destruction of all rainforests and tile inching of all Arctic ice.
