Katie Purvis-Roberts, professor of chemistry and environmental science, co-authored a paper assessing dynamic urban emissions displacement in Malaysian photovoltaic applied fueling stations. The paper, published in Cleaner Engineering and Technology, found that the photovoltaic system refurbishment of a fueling station in Malaysia would produce cost and emissions savings, but that the return on the refurbishment investment would take approximately eight years. “In reality, fossil fuel divestment is impossible due to its reliability,” the co-authors write, “but renewable technology can improve the built environment and air quality management in the city.”
