The fate of the lithium-ion batteries in electric vehicles is an important question for manufacturers, policy makers, and EV owners alike. Today, EVs are a still a small piece of the automotive market.
With New Manipulation of Benefit-Cost Analysis, the Trump EPA Attempts to Hide Bodies in the Fine Print
Julie McNamara, Senior Energy analyst | June 4, 2020, 4:51 pm EDT Nobody reads the fine print. Or that’s the apparent thesis of the Trump administration’s EPA, anyway, in its newly proposed spin on benefit-cost analysis. Here, now, the agency with its mission to protect human health and the environment is attempting to shovel tens of thousands of pollution-caused deaths off the main page and into the margins to make regulatory inaction pencil out.
10 Things That the Scholarly Community Can Do to Stand in Solidarity
Acknowledge the history Science has a deeply problematic relationship with race. The dimensions of this history are many, and most remain in operation to this day. Don’t expect your Black colleagues or friends to educate you on this history whenever you deem it necessary to learn about it. They have already written countless studies to help you understand it. Read them. Cite them.
The Second-Life of Used EV Batteries
When an electric vehicle (EV) comes off the road, what happens to the vehicle battery? The fate of the lithium ion batteries in electric vehicles is an important question for manufacturers, policy makers, and EV owners alike. Today, EVs are a still a small piece of the automotive market. Many of the batteries coming off the road are being used to evaluate a range of options for reuse and recycling.

Lunch in the Time of COVID-19: What Schools Need Now to Ensure Kids Don’t Go Hungry During a Pandemic
Karen Perry Stillerman, senior analyst, Food and Environment | March 10, 2020, 3:03 pm EDT Regular readers will know that I take a pretty dim view of the Trump administration’s Department of Agriculture and many of its anti-science, anti-farmer, and just plain mean-spirited actions over the past three years. The administration is also getting a lot of things (very) wrong in its response to the novel coronavirus disease (COVID-19).
How Long Will My EV Battery Last? (and 3 Tips to Help it Last Longer)
The low battery indicator on my phone seems to be an increasingly frequent source of stress. It turns out I’m not alone as there is real social anxiety associated with a dead cell phone battery. As batteries age, less of the stored energy becomes accessible, so less time for sending email and playing Candy Crush away from the plug. For an electric vehicle (EV), low battery fear can contribute to what’s known as ‘range anxiety’, an often cited barrier to wide-spread EV adoption.
