I saw a presentation on plug in electrics. According to presenter, the tail pipe emissions from a gas engine are as bad as the dirtiest, nastiest coal fire plant. So if the power used to charge the battery comes from renewables, nuke, or cleaner coal, you are better off with a plug in electric. Go ahead and call your power company and ask them exactly what plant your power comes from. I am sure the will be able to tell you right away.
There wasn’t much discussion about the pollution involved in battery manufacturing or the fact that the batteries are expected to last less than 10 years. When asked about the pay back period, all the presenter could say was “what is the pay back on leather seats”. Right now it is just a feel good option.
The big advancement is going to come with smart meters and what not when you can charge your car during off peak times and then use the batteries to power your house during peak when the car is parked in the garage. Energy storage is the future.
