No offence meant! So here's the interesting thing, our known reserves today are bigger than they were in the 19th century and paradoxically are getting bigger every year even though we are using more and more oil. Until this situation ends there's no need to waste resources developing an alternative energy source (assuming the sole reason for doing so is to mitigate running out of oil). We are essentially running into oil rather than out of it. Higher oil prices automatically command resources and people to direct their attention to oil production. This is why we never run out of any resource, as soon as the price rises people move into the field (in order to get higher wages/returns) to solve the problem.
