Scientific American Features Azevedo/Hittinger Piece

The article by Robert Fares highlights my recent work: “While there is no doubt that energy storage can help integrate renewable energy with the grid, a recent study by Eric Hittinger of the Rochester Institute of Technology and Inês Azevedo of Carnegie Mellon University indicates that bulk energy storage would most likely increase total U.S. electricity system emissions if it were installed today, because it would typically store electricity generated from fossil fuels rather than renewable sources.” Read the rest here.

Which Vehicle Holds the Smallest Carbon Footprint?

A new study by Carnegie Mellon University researchers finds that in some regions of the United States electric vehicles have the smallest carbon footprint, but in other regions, hybrids do. Carnegie Mellon Professor of Engineering and Public Policy and Mechanical Engineering Jeremy Michalek, Associate Professor of Engineering and Public Policy Inês Azevedo and University Professor of Civil and Environmental Engineering Chris Hendrickson, together with Mili-Ann Tamayao, a professor at the University of the Philippines who earned his Ph.D. in engineering at CMU, studied carbon dioxide emissions of different vehicles in different regions.

Michalek, Hendrickson, Azevedo Highlighted in Torque News

A paper recently published by Jeremy Michalek, Chris Hendrickson, and Ines Azevedo, titled “Regional Variability and Uncertainty of Electric Vehicle Life Cycle CO2 Emissions across the United States” was recently featured in Torque News. The study shows that the all-electric Nissan LEAF emits less CO2 than the Toyota Prius Plug-in and the Chevrolet Volt.

Wired Magazine features article on Inês Azevedo’s research on electric cars and infrastucture funding

“AMERICA NEEDS BILLIONS to fix its crumbling, crappy roads. But no one’s got that kind of money and the Highway Trust Fund – Uncle Sam’s primary means for paying for road construction and repairs – teeters on insolvency. That’s because it’s funded largely by a federal fuel tax that’s been parked at 18.3 cents per gallon since 1993, even as cars use less gas than ever.” Read more at

Daniel Posen and Inês Azevedo recently published a blog post on The Energy Collective

In this short essay, they discuss the potential benefits of expanding the scope of the U.S. Renewable Fuel Standard (RFS2). A link to the article is available here.

Researchers Propose Solutions To Reduction in Revenue from Gasoline Tax

Researchers from Carnegie Mellon University’s College of Engineering have found that an increased adoption of electric vehicles (EVs) would result in reduced consumption of gasoline and consequently a decrease in gasoline tax revenue that currently supports infrastructure development and maintenance in the U.S. The scientists say the loss of tax revenue could be between $200 million and $900 million by 2025, depending on the EV adoption rate.
