You seem to miss the absolute impact that the petrochemical industry has had on humans. Not only does it supply fuel that enables us to ship goods cheaply all over the planet, but that is actually only about half of the use.... Without petrochemicals, you would not have pretty much anything you look at in your home. All of your furniture and clothing is made with synthetic fibers coming from petrochemicals, not to mention every single item that you own that contains some form of plastic, (which is pretty much everything), and medical equipment as well as most medicines that you take and all of the artificial heart valves, and your roof, and the insulation in your wiring, and the paint on your walls, asphalt, the synthetic rubber in your cars tires, etc.... the list is endless. If there was no such thing as oil, almost NOTHING of what we have today would exist, and there is no other source for all of the things that keep so many people alive on the planet today. The fact is, is that without oil, we wouldn't ever be able to build solar power plants in the first place.
You are living in a fantasy world if you think that there is any other resource on this planet that would have replaced oil if it wasn't around. Without it, we would still be living as we were in about 1880, our lives would be much shorter, our technology would be crap, we would still be dying from a myriad of deseases that we no longer suffer from, and there would be far more people starving to death on the planet or not living past childhood then there are now. Frankly we would probably actually be polluting much MORE now if oil had not been around to create the newest products that we can use so cleanly now. We would have probably been forced to cut down every tree and kill every animal in an effort to keep up with demands for resources that petrochemicals now satisfy
Take a look at this subject, and educate yourself. See if you can clearly think about what modern technology we would have been able to create to take us forward into a cleaner world WITHOUT oil.
It may be time to move past it soon.... but without it, we would not have the capability of creating any new technology in the first place.
