"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 wired.com.
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.
To transition to sustainable energy systems, we need to look at technology, policy, innovation, and people, says Engineering and Public Policy Associate Professor Inês Azevedo. In this video, she discusses how she researches each of these aspects to help us successfully move to sustainable energy systems.
"Bulk energy storage is generally considered an important contributor for the transition toward a more flexible and sustainable electricity system. Although economically valuable, storage is not fundamentally a "green" technology. Hittinger and Azevedo model the economic and emissions effects of bulk energy storage providing an energy arbitrage service. They find that net system CO2 emissions resulting from storage operation are nontrivial when compared to the emissions from electricity generation."
Jornali, a major Portuguese newspaper, named Ines Azevedo one of the top immigants they would like to see return to the country.
Azevedo was recently featured in a video explaining some of the recent research with Kyle Siler-Evans, Granger Morgan, and Jay Apt, addressing the question: "Are you REALLY saving the environment investing in a wind farm or solar power plant?"

This video is based on a paper, "Regional variations in the health, environmental, and climate benefits of wind and solar generation," in the Proceedings of the National Academy of Sciences
Stanford Energy Resources Engineering Professor Inês M.L. Azevedo co-authors a report from the U.S. National Academy of Sciences on the topic of Recuding Fuel Consumption and Greenhouse Gases for Medium and Heavy Duty Trucks.
