[Green Car Congress] Researchers at Carnegie Mellon University (CMU) have published two new policy briefs, along with accompanying videos, about the benefits of electrified vehicles and the potential for their adoption in the US. The briefs condense the findings of a number of recent papers coming out of the CMU group led by Professor Jeremy Michalek.
The first—“Electric Vehicle Benefits and Costs in the United States”—shows that the benefits of vehicle electrification vary based on vehicle type; driving style; climate; how supplying electricity is generated; and time of charge. To achieve the best outcomes, the brief suggests, plug-in vehicle adoption should typically be focused on HEVs and PHEVs by city drivers in mild-climate regions with a clean electricity grid, such as San Francisco or Los Angeles. Further, drivers should not be encouraged to charge at night in coal-heavy regions.
As the electric power grid becomes cleaner, as electric vehicles become cheaper and faster to recharge with longer range, and as policies adjust, electrification may offer benefits across the board, the brief notes.
