Q+A: Post-Paris, America’s First Step To Reduce Greenhouse Gas

January 4, 2016

As part of the 2015 Paris Climate Conference in December, the United States supported a proposal to cut global emissions of greenhouse gas in hopes of stalling global temperatures from rising as much as 3.6 degrees Fahrenheit by the year 2100 — a benchmark scientists say would be of great concern. Days later the U.S. Department of Energy took the first step toward reaching this goal when it announced new energy efficiency standards for commercial air conditioners and furnaces. According to the DOE, the new standards are the largest energy efficiency standard in US History with expected utility savings to business of $167 Billion and a reduction in carbon pollution of 885 million metric tons over 30 yrs

Read a Q+A with Drexel environmental engineering professor Patrick Gurian, PhD, who recently led a team including researchers from the the A.J. Drexel Institute for Energy and the Environment that produced a plan for the city of Philadelphia to cut its greenhouse gas emissions by 80 percent by the year 2050, to see why this was the first move coming out of the Paris meeting and what other carbon-reducing changes could be on the horizon.

Cleaning Wastewater With Pond Scum

January 5, 2016

A blob of algae scooped from a fountain on South Street almost two years ago, has seeded a crop of the green stuff that Drexel University researchers claim is more effective at treating wastewater than many of the processes employed in municipal facilities today.  Christopher Sales, PhD, an assistant professor in the College of Engineering and a member of the research team at the A.J. Drexel Institute for Energy and the Environment, aims to improve wastewater treatment with a little help from algae and its symbiotic relationship with the bacteria to remove excess nitrogen from water.


Diagnosing 'Sick' Buildings to Save Energy

September 9, 2015

"Are you feeling too cold right now? Too warm? Is your office's air a little stale today? On average, Americans spend 90 percent of the day indoors, in a controlled environment. Controlling that environment, at least in the workplace, is the Sisyphean labor of building operators. Jin Wen, PhD, an associate professor in the College of Engineering and co-director of the Building Science & Engineering Group, is developing a powerful tool that can analyze the big data generated by various components in building control systems ..."

Drexel Reseachers First to Detect Air Quality Effects of Natural Gas Extraction in PA's Marcellus Shale Region

May 19, 2015

While there have been a number of studies focusing on water quality impacts related to natural gas extraction in shale regions across the country, few have looked at the effect on air quality. In a paper recently published in the journal Environmental Science & Technology, Peter DeCarlo, PhD, an assistant professor in the College of Engineering and College of Arts and Sciences and IExE affiliated faculty member, and J. Douglas Goetz, a doctoral researcher in the Drexel Air Resources Research Laboratory, present the findings of a two-month mobile air monitoring campaign in several counties in the northeastern and southwestern Pennsylvania.

Using Viruses to Help Water Blow Off Steam

March 25, 2015

Matthew McCarthy, Assistant Professor in the Deparment of Mechanical Engineering and Mechanics, and IExE affiliated faculty member, is using a common plant virus to improve the phase-change heat transfer of fluids. McCarthy and his team in the Multiscale Thermofuidics Lab, are utilizing "legions of viruses that infect the leaves of tobacco plants to potentially make power plants safer, heating and cooling of buildings more efficient, and electronics more powerful". McCarthy says "Phase-change heat transfer plays an important role in everything from power generation to water purification, HVAC and electronics cooling.  Increasing performance of these systems would translate to significant improvements in the way we produce, consume and conserve our energy and water resources".

Are We Wasting Our Energy (And Land) on Biofuels?

February 4, 2015 

"A recent report by the World Resources Institute suggesting that policy changes are necessary in Western countries to phase out the use of agricultural land for growing crops that will be made into biofuels. In the United States alone, 30-40 percent of corn crops are being converted to fuel additives. But the report indicates that our efforts to turn plant matter into liquid fuel are barely a drop in the gas tank when it comes to satisfying the world’s energy demand." Sabrina Spatari, PhD, Associate Professor in the Civil, Architectural and Environmental Engineering Dept. answers questions raised by the report and biofuels more broadly.

On The Road Again…This Time, It’s For Air Quality Testing

June 24, 2014

“Cities like Philadelphia have a network of fixed air pollution monitors that track our air quality for regulatory purposes,” said Peter DeCarlo, PhD, an assistant professor in the College of Engineering and the group’s advisor. “These sites are expensive to run and maintain, so there is a limit to the number of sites that can be supported. A mobile measurement facility allows us to take our measurements anywhere, and characterize air quality and emissions from facilities at a neighborhood to city scale, complementing the fixed site monitors run by the city.”

<aDr. Mimi Sheller, Director, Center for Mobilities Research and Policy, and Professor of Sociology, publishes Aluminum Dreams, The Making of Light Modernity.</a

June 9, 2014

"Despite the fact that aluminium makes up one-twelfth of the Earth’s crust, and is the third most common element on the planet (after oxygen and silicon), aluminium is hard to get at in its pure form and exists mostly locked away in bauxite. It takes four tonnes of bauxite to create one ton of primary aluminium and the big producers are Australia, Brazil, China, Guinea, Jamaica and Vietnam. Heavy consumers include the United States and the Middle East, and this unequal distribution has the potential to create political tensions such as those we’ve seen in the international oil markets. Other issues, such as encroachment onto indigenous peoples’ lands, human rights and environmental degradation make production something of a mixed blessing." Click here to read a Q&A with Dr. Sheller.
