Electric vehicles emit 20 percent less heat than gas-powered cars, which helps mitigate the urban heat island effect and An electric car recharges its battery. could lead to lower air conditioner use in major cities, according to research published in the journal Scientific Reports. Heat emanating from vehicles is an important contributor to the heat island effect ā€” the difference between temperatures in heavily urbanized areas and cooler rural regions ā€” and a shift toward electric vehicles could help, the researchers say. They used data from Beijing in the summer of 2012 to calculate that switching vehicles from gas to electricity could reduce the heat island effect by nearly 1 degree C. That would have saved Beijing 14.4 million kilowatt hours of electricity from air conditioning and cut carbon dioxide emissions by 11,779 tons per day, the study says.
