Since around 60% if the electricity generated in the US comes from fossil fuels trading a gas car for an EV is a wash in that department. You're trading the use of one fuel type only to increase demand on another. If there was an increase in nuclear and renewables to that 60% mark then it could be a good trade in that respect. I could also charge at home utilizing mainly solar but that brings me to the next draw back the batteries. If the lifespan of a battery is 8 years your range or capacity would begin to degrade before that which would reduce your range. Add to that the cost of the batteries and you're looking at replacing a EV every 5 years or so. In addition, where do these old batteries go? How do we dispose of them? What issues does that cause? Making the batteries is another issue not discussed. What effect will that have with increased EV usage.The problem with EV's is the demand for electrical energy from power plants powered by fossil fuels.
Nuclear and natural gas powered plants are the only answer to solve the problem. What is the cost of replacing the batteries and pollution the dead batteries cause?
I like the hybrid idea as the non-plug in types cut fuel usage without a lot of the added problems of a full EV but for now it seems moving to an EV is trading one problem for another.
