This episode of the TEOTWAWKI specials, we're focusing on every crazed doom-prepper's favourite scenario for the end of the world - Peak Oil. Our society runs on oil and petroleum products (sadly, still). These fossil fuels are the fossilised remains of plants and animals that died millions of years ago, and they take tens of thousands of years to form. So it seems to be a perfectly reasonable assumption to make: one day, we are going to run out of fossil fuels, and we will need renewable forms of energy.  But what if we run out of fossil fuels before transitioning to renewables? What if surging oil prices, and steady demand, causes us to pursue more and more dangerous and environmentally unsound methods of extraction? What could the consequences of our dependence on oil be, and how can we hope to get around it?  You can find us on Twitter @physicspod, where you'll even find a donate link for the show if you want to support what we do. Fire all questions @physicspod or towards physicspod@outlook.com . Until the oil runs out - stay safe.
