Like the legendary falling apple that hit Isaac Newton and led to his groundbreaking insight on the nature of gravity, COVID-19 could provide unintended glimpses into how complex Earth systems operate, according to a new Stanford-led paper.
Fan Tong and Inês Azevedo examined the most beneficial vehicle fuel technology for transportation in the US and the trade-off between decarbonization and air pollution mitigation. The results show electric vehicle use must accompany clean energy grids to mitigate both climate change and air pollution.

In an article by Nicholas Muller and Daniel Raimi in Resources magazine, they discuss the paper from the journal Proceedings of the National Academy of Sciences called, “Fine particulate matter damages and value added in the US economy" authored Nicholas Z. Muller, Peter Tschofen and Inês M.L. Azevedo.
Costa Samaras at Carnegie Mellon University and Inês Azevedo at Stanford University are quoted in Forbes article by Jeff McMahon regarding the Power Sector Carbon Index, which track the CO2 emissions of the U.S. power sector. The Power Sector Carbon Index shows that carbon intensity of the U.S. power sector reached a new low in 2019, more than a third below its 2005 level.
Studies have been exploring the connection between reducing climate-warming emissions and healthier air, and how that plays out at a local level. But Brian Sergi, Inês Azevedo and colleagues wanted to take an even more granular, county-by-county approach to assess how a combined climate-and-health-driven strategy for the U.S. electricity system might play out compared to one prioritizing only climate.
The economic impacts of Covid-19 in India are likely to be quite steep. Madalsa Singh and Aniruddh Mohan contend that any stimulus package to restart the economy has to be ‘green’; it must encourage an economic path that reduces the carbon intensity of the economy, instead of propping up business models that have no place in a future low-carbon world. They further discuss what steps can be taken in three key areas: electricity, transport, and the urban economy, to deliver broad-based growth and improve environmental outcomes.
When it comes to the precise technological makeup of a future decarbonized economy, expert opinions diverge. Engineers and economists, for the most part, imagine solutions that bundle several approaches, with both CCS and nuclear power acting as important complements to renewables.Political scientists, on the other hand, tend to see a bigger role for renewables.
U.S. farms cost the economy more in health and environmental damage than they contribute to the economy, according to a recent study in the Proceedings of the National Academy of the Sciences (PNAS). For 20 economic sectors, the study compares the cost of premature deaths from particulate air pollution to the value added to the economy. Farms performed worst, driven down by animal agriculture.

Medium- and heavy-duty trucks, motor coaches, and transit buses - collectively, "medium- and heavy-duty vehicles", or MHDVs - are used in every sector of the economy. The fuel consumption and greenhouse gas emissions of MHDVs have become a focus of legislative and regulatory action in the past few years. This study is a follow-on to the National Research Council's 2010 report, Technologies and Approaches to Reducing the Fuel Consumption of Medium-and Heavy-Duty Vehicles. That report provided a series of findings and recommendations on the development of regulations for reducing fuel consumption of MHDVs.
In an article by Sam Jarman of Physics World, experts Brock Glasgo, Inês Lima Azevedo and Chris Hendrickson agree that a widespread adoption of direct current (DC) power systems in commercial and residential buildings could offer significant advantages over alternating current (AC) systems, according to a new study.
In the article A fork in the road for U.S. power, Ben Geman of Axios discusses the nationwide trend toward a lower-carbon mix, while the Trump administration is preparing steps that would halt coal's decline. The focus of the article resides heavily with the paper Assessing the evolution of power sector carbon intensity in the United States, by Carnegie Mellon University Post-Doc, Greg Schivley, and Professors Inês Azevedo and Constantine Samaras.
In the article by David Roberts of Vox, Roberts discusses the secret behind energy storage in the US. "The way it’s typically used in the US today, it enables more fossil-fueled energy and higher carbon emissions. Emissions are higher today than they would have been if no storage had ever been deployed in the US." In his article, he references a paper written by Eric S.
