Conventional Hybrids Better
For Climate than EVs in Most U.S. States
Conventional gas-powered hybrid vehicles are still better for the climate than all-electric cars in most U.S. states, in part because these states still rely heavily on fossil fuels to produce electricity, according to a new report
. In 39 states, high-efficiency hybrids, such as the Toyota Prius, produce fewer carbon emissions during their lifecycle than the least-polluting electric cars, an analysis by Climate Central found. Although an increased reliance on cleaner energy sources in some parts of the country doubled the number of states (32) where driving electric cars would be more environmentally friendly, that advantage disappeared when analysts also considered the high emissions associated with building the batteries and other components for the EVs. In 11 states, the best all-electric cars are better for the environment than gas-powered hybrids, even when manufacturing is taken into account. In 26 states, plug-in hybrid cars are the most climate-friendly vehicles, the analysis found.
