“… the main claim for pushing widespread EV [electric vehicle] use is that it would radically reduce global carbon-dioxide emissions. It won’t. In fact, an all-EV America would barely trim 8 percent off world oil demand. And the impact on carbon-dioxide emissions would be smaller.”
“Why? It takes energy — the equivalent of 80 to 300 barrels of oil — to fabricate a battery that can hold energy equal to one barrel. Thus, the energy used to make batteries means EVs carry a carbon “debt” that greatly diminishes, or can even cancel out, emissions saved from avoiding oil.”
…
“And by the way, as the International Energy Agency notes, expected efficiency improvements for combustion engines will save 300 percent more global energy than will all the EVs forecast to be on the roads by 2040.”
