That's just not true. If you're in the USA, today, you can walk down to a Nissan dealer and order a Leaf : a highway capable (relatively, for new tech) affordable family car which runs on electricity. Electricity is a far superior power source than oil, given it can be generated in a variety of ways. And the technology is here, today, available. The technology to generate and distribute electricity is here, today, available.
The reason we're not all in electric cars is a combination of inertia and newness of the tech. But if the oil price doubled in the next 12 months, the Leaf assembly plant would be running at full capacity. But I disagree strongly that there is no alternative to oil.
Malthus was wrong and will continually be proved so. You can blindly just accept human ingenuity will drive things forward as long as people are allowed to keep the bulk of the reward for their efforts. It might be a leap of faith, but it's a better one to take than living with a doom and gloom mentality.
