Similar to the idea that electric cars are net worse for the environment because some of the materials used to make them. Worse than 20 years of burning gasoline in an ICE car? It's so ridiculous.
it depends where your electricity comes from actually. In west Virginia it comes from coal so is worse than a hybrid but still better than non-hybrid gas cars (in terms of CO2)
No it's not. The efficiency of an EV Motor > efficiency of ICEV motor. Even with 100% black coal. The carbon is reduced by about 30% IIRC (that number can and does improve as the grid greens).
