Do we need them? Most certainly. I don’t believe it is possible for the planet’s resources to support all of China and India at the consumption rates in the West, an astounding 200kWh per head, every day. We find ourselves in a cross over period of history. The internal combustion engine has 100 years of development behind it, making it to at least the nearest order of magnitude the best it can be, yet still only 20% efficient. The nascent EV alternative is woefully expensive, poor in performance and comes with use constraints. No surprise that it seems uncompetitive.
