Electric cars vs gasoline cars. Who wins on climate change? We’re two engineers and we’ve been asking the same question (and finding some pretty cool answers). Ask us anything!
Hello Reddit! Following years of investigation, we’ve just released a report on the global warming emissions of electric cars. We looked at everything from battery manufacturing to regional charging emissions to vehicle disposal and re-use. Our findings show that today’s average electric cars are 50% cleaner than equivalent gas cars, even on a lifecycle basis—and they’re only getting cleaner.
Rachael Nealer is a Kendall Fellow at the Union of Concerned Scientists (UCS) and has worked for the U.S. Environmental Protection Agency, modeling the lifecycle greenhouse gas emissions from biofuels. She has a PhD in civil and environmental engineering and engineering and public policy from Carnegie Mellon University.
Dave Reichmuth is a senior engineer at UCS and is focused on oil savings and vehicle electrification. Before UCS he worked at Sandia National Laboratories, modeling the costs and benefits of battery electric and hydrogen fuel cell vehicles. Dave has a PhD and masters in chemical engineering from University of California-Berkeley.
We’ll be here for about 2 hours. Ask us anything!
Edit: That's it for us. Good stuff, as always!
