Investment in electrical transmission and distribution (T&D) systems could significantly reduce air pollution, according to a study led Lauren Janicke, an undergraduate in civil and environmental engineering (CEE), and Destenie Nock, assistant professor of CEE and engineering and public policy.
Janicke, Nock and their co-authors noted that, "Globally, 10.2 million premature annual deaths can be attributed to fossil fuel generation and associated PM2.5 emissions (fine inhalable particles less than 2.5 millionths of a meter in size), a large part of which comes from the electricity sector."
In analyzing several scenarios, the team found that improving T&D efficiency between 5% and 33% would decrease global median emissions by as much as 40%.
