Electric Cars: Are They Better for Your Pocket and the Climate Right NOW?

Last week, I read a blog post from Connecticut Fund for the Environment President Curt Johnson, and he reaffirmed what I already expected: my next car will likely be an electric vehicle (EV). I currently drive a Toyota Prius hybrid, but when I bought it in 2013, the price to purchase and to operate an EV did not work out, so I chose the Prius, which has very reliably achieved 50 mpg over the last six years.

As an engineer who admittedly knows nothing about cars, I feel like the information out there on EVs is either slightly biased (i.e., published by EV manufacturers) or not transparent enough with the math to convince me. So I set out to create a blog post that was unbiased and transparent. I liked this one from Tom Murphy, an associate professor of physics at the University of California, San Diego, so hopefully I’m making it a bit more user-friendly and applicable to your current/local situation.

I just wanted to know two simple things (and admit to ignoring a long list of other factors that influence the type of car most people will choose to drive):

Number 1: At what gas price is an EV cheaper to drive per mile?

Number 2: While EV tailpipe emissions are zero, is my local electric grid clean enough that it’s a good idea, right NOW? I know my next car will be electric, I just don’t know WHEN the grid will be clean enough that it’s better for the environment for me to switch.

When I began writing this article, I had no idea what the answers would be.


Tech Notes: Accessible Electric Vehicle Charging Stations

Electric vehicle charging stations must provide a basic level of accessibility, including controls within reach and user access.

Over the past several years, as the desire for more sustainable and environmentally friendly transportation has increased significantly, we have been seeing a corresponding increase in the number of electric vehicle charging stations provided in parking lots and garages. Applicable federal, state, and local accessibility laws and building codes may not specifically address how to make these charging stations accessible, but that does not mean they are exempt from compliance. Under most regulations, where electric charging stations are provided, at least one must be accessible.

But what does an accessible charging station look like?
