It's science. Oil that we extract from the ground takes millions of years to become oil, and by time it's all sucked up in the 200 years of industrialization, we'll be waiting a bit for replenishment of those deposits.
What is possible (although not likely at the current rate of development) is we'll come up with a synthetic means of running combustion vehicles that doesn't puke more CO2. The tech is there but is not easily ramped up to the levels we need for full replacement. It's likely we'll be seeing an electric future in stages. Stage 1 are hybrids, cars that either use gas as generators or use electric engines for city / low speed travel. Stage 2 will be full electric. Stage 2 is a long way off due to battery tech and charging infrastructure being very far behind what is necessary.
The answer to the power grid issue handling the additional electric cars is home solar power (and/or wind) and batteries for off hours use. People are already doing this, and as that industry grows the costs will come down. Additionally, power companies are starting to see the clouds on the horizon and loosening their grip on the industry, allowing more and more people to sell excess power back to the grid. This helps the home owner with solar as well as the power company who doesn't have to build another costly station or dam or huge solar/wind farm. The vision for power companies of the future is to have them simply connect us all together, rather than be the sole source of power generation.
