People using energy-efficient smart thermostats are willing to sacrifice comfort and control to save relatively small amounts of energy that could add up if enough people sign on, a Georgia Tech economist reported in a recent study. With federal and state energy policies targeting aggressive decarbonization in the next 15 years, smart technologies have the […]
Who breathes cleaner air when Americans put solar panels on their roofs? Using plant-level emissions data, an air-pollution transport model, and census-block demographics, Bobby Harris (Georgia Tech)—the study’s EPIcenter affiliate— and Travis E. Dauwalter (Artera Services) show that today’s rooftop solar fleet delivers $0.77 in environmental benefits per person annually and disproportionately benefits higher-income households. […]
Workplace EV charging congestion threatens corporate decarbonisation targets. Asensio, Apablaza, Lawson and Walsh (Georgia Tech; EPIcenter affiliate Omar I. Asensio) examine whether a tiered price of $1 per hour after 4 hours and injunctive “charging-etiquette” emails can curb charger over-stay across 105 stations and 84 employees. High-frequency session data are analyzed with sharp and dynamic […]
Federal housing block grants may be an untapped tool for energy-efficiency policy. EPIcenter affiliate Omar Asensio and his coauthors Churkina, Rafter and O’Hare (Georgia Tech, Harvard Business School and Georgia State University) link 5.9 million monthly utility bills with 16 years of Community Development Block Grant (CDBG) and HOME Investment Partnerships projects in Albany, GA […]
How can a country minimize long-term power-system costs when future electricity demand is uncertain? Yuang Chen (PhD ISyE Georgia Tech and now assistant professor at the Chinese University of Hong Kong at Shenzhen), Beste Basciftci (PhD ISyE Georgia Tech and now assistant professor at the University of Iowa) and Georgia Tech’s Valerie M. Thomas (an […]
When a hurricane is coming, can a city with lots of electric cars top-up all those batteries fast enough without frying the local power grid? Three Georgia Tech engineers—Alejandro Owen Aquino, Samuel Talkington and EPIcenter affiliate Daniel Molzahn—built a computer model to find out. Using realistic-but-not-real data from Greensboro, North Carolina, the model shows that […]
Across the country, solar farms have experienced rapid growth, supported by advancements in technology, cost reductions, and policy initiatives such as state-level renewable portfolio standards and tax credits. As shown in Map 1, roughly 18% of ground-mounted PV facilities in the U.S. were installed between 2021 and 2023, with a notable portion of these projects […]
To gain a deeper understanding of the current energy landscape in Georgia and the southeast, this blog series examines emerging topics in the energy sector, provides timely information on key energy challenges and opportunities, and discusses how Georgia and the southeast are adapting to meet growing energy needs while embracing sustainable energy goals and supporting […]
Listen to the Curtailment 101 podcast: EPIcenter affiliates Gaurav Doshi and Matthew Oliver’s article in The Energy Forum discusses the why grid operators occasionally curtail wind and solar output when transmission capacity is insufficient or demand is low, and the economic and environmental impacts of these decisions. Congestion-based curtailment arises when the transmission network cannot […]
Municipalities have shunned solar farms because these large installations are believed to reduce property values. Now, in a first-of-its-kind study, Georgia Tech economist Laura Taylor shows that utility-scale solar farms don’t adversely affect sales prices for agricultural land. The work, published recently in the journal Land Economics, may help inform local decision-making. “As zoning boards […]
The assistant professor in applied economics researches, among other topics, ways to make the benefits of large electrification projects more transparent. It’s a chicken and egg situation: Should renewable energy projects launch first hoping that transmission lines to pipe generated power to distant places will follow on their heels? Or should the transmission lines be […]
As summers get increasingly hotter, expect more adverse effects on health. EPICenter grant recipient Pengfei Liu is exploring the connection between the two as a necessary step in climate adaptation. The trendlines point in one direction: The ten hottest years on record were all just in this nascent century. Summers, especially, are getting hotter. And […]
When it comes to finding solutions to climate change, there’s no shortage of technologies vying for attention, from renewable energy to electric vehicles to nuclear energy. One such contender, solar geoengineering, is favored by proponents who say it could quickly cool the planet and give the world time to fully implement efforts to limit emissions […]
Smoke cloud rising from a brush wildfire burning in San Francisco, California (Source: Adobe Stock) You’re managing the Texas Panhandle’s power grid. Heavy winds are blowing, and a worn-out utility pole ignites a fire by crashing onto a transmission line. Luckily, the fire department arrives quickly, putting out the fire before it spreads to nearby […]
While the U.S. federal government has clean energy targets, they are not binding. Most economically developed countries have mandatory policies designed to bolster renewable electricity production. Because the U.S. lacks an enforceable federal mandate for renewable electricity, individual states are left to develop their own regulations. Marilyn Brown, Regents’ and Brook Byers Professor of Sustainable Systems in […]
The NSF grant winner and associate professor is working to improve the resilience of power grids while also indulging in his other love: history. Daniel Molzahn will readily admit he’s a Cheesehead. Born and brought up in Wisconsin, the associate professor at the School of Electrical and Computer Engineering attended the University of Wisconsin, Madison, […]

Master of the rebound — Economist Matthew Oliver measures the sometimes concealed costs of pivoting to clean energy Students in Matthew Oliver’s economics of environment and international energy markets classes likely don’t have a clue about his unusual journey to the lectern: “I was bent on being a rock and roll musician from the time […]
Shifting focus from theoretical physics to research on environmental problems over the course of her distinguished career, the professor is working to decarbonize the industrial complex. Climate change might feel like an intractable problem but Valerie Thomas wants us to take heart. “It’s not hard, we make it hard. We can recreate our industrial system,” […]
