Let's get real, you can make oil for 80-100$ a barrel from coal, and around 200$ a barrel from air and nuclear power. There is nothing magic about long chain hydrocarbons they are just really cheep right now. So we use them for building roads, (Asphalt), lubricants, plastics, fertilizer, and fuel. Something like 20% of our GDP depended on whale oil we found a cheaper alternative. Once supply becomes expensive you will see oil demand fall like a stone.
