Hydrocarbons are dead in the long run. No doubt. At some point we just plain run out. Every petroleum producer lies about their reserves; that's just a fact of life. But it makes it impossible to say whether we've got a few decades or a few centuries left. Wind, solar, and hydro are the other main sources of electricity, but their contribution is still small compared to fossil fuels. If we are to keep anything like the current standard of living, new sources must be found or the use of renewable sources greatly expanded. There are other possible sources such as geothermal and ocean movement, by they are limited in the one case and no one has figured out how to economically exploit the other. Batteries are improving. Remember when all cars had was lead-acid batteries and everything else was lead-chloride small capacity batteries? Now many types exist. As research continues, we can hope that one will be found that will change that expensive toy into a practical reasonably priced car.
