Yeah, there are technical alternatives already, but it's a question of econonmics. If there is less oil produced prices will rise and less will be consumed. There are many alternatives, but today oil is just cheap enough for many uses. Natural gas is one alternative, that can be used instead of oil to fuel cars and for heating. There is plenty of that around. If the price of oil rises a lot more than natural gas, more people will run cars on natural gas. Electrical cars and wood gas are other technologies that have been around for a long time, but just aren't quite as practical. But if oil becomes a lot more expensive, the alternatives will start to look better in comparison.
