Not all electricity is the same

California’s new law requiring solar panels in new residential builds has just gone into place.  That’s pretty cool– I’m hoping that the resultant increase in demand will cause technology improvements that will make solar worth it for my house by the time we need a new roof.

California already has cleaner energy which means it’s a great place to drive an electric car.

But not every state gets a lot of energy from renewables and (not great but still) relatively cleaner forms of energy generation such as nuclear power or natural gas.  Some still have electricity generation that may be dirtier than the same amount required to fuel a gasoline-powered hybrid car.  In these places, it’s better for the environment to buy a hybrid than to buy an electric vehicle.

Here’s an article from 2015 that describes this situation in more detail.

And here’s a nifty NYTimes article from 2018 that shows where your state gets the majority of its energy (or at least where it did back in 2017):

The US government also has a tool that’s hopefully more up-to-date (but actually looks like it’s still using 2017 data) that provides a ton of information on energy generation and consumption by state.  You can see why CA is a great place for electric cars, but say, West Virginia should stick to hybrids.

What kind of electricity do you have?  Has this influenced your decision about what kind of car to buy?
