Electric cars are often praised as the cleaner future, but the full lifecycle emissions—from battery mining to electricity generation—paint a murkier picture. A 2022 study by the IEA showed that manufacturing an EV can produce up to 70% more CO2 than a comparable gasoline car, mostly due to battery production. However, over a 15-year lifespan, EVs typically still come out ahead if the grid isn't coal-heavy. Should we be pushing EV adoption as aggressively as we are, given the upfront environmental cost and the fact that most of the world's electricity still comes from fossil fuels? I'm genuinely unsure if the timeline works in our favor, but the long-term trend seems clear.
