Aaron, you are correct that
Aaron, you are correct that it's not good to use coal energy for anything, even powering your house, right? That's why plug-in vehicle advocates always work for renewable energy to power out homes and cars. It's incredibly easy, and in most cases, cost effective. After buying a 3 kW PV system in 2002, then buying an EV that same year, I have driven 105,000 miles on kWh generated from the sunlight falling on my roof. My electric bill averages a mere $100 per year for both the house and car.
My solar system paid for itself as of last year. For the rest of my life, I get free energy from the sun.
Before you say anything negative about EVs, please consider the full picture. We need these cars, fast.
