Heartland Director of Communications speaks with Heartland Senior Fellow for Energy and Climate Fred Palmer about a recent cover story in the Economist magazine about the supposed impending death of the internal combustion engine. Not so fast, says Palmer. While electric cars may be more prevalent in the future, that future is a long way off. The energy density of the internal combustion engine – perhaps the most significant engineering accomplishment of the last 100 years – cannot be matched by current or even soon-to-come battery technology. The future of fossil fuels is still strong, so it’s a good thing we have a couple of centuries of it below our feet to exploit.
