Data suggest there are no harmful electromagnetic emissions from plug-in cars. There is no broad agreement in the United States over what level of exposure to electromagnetic fields may constitute a health hazard, and there are no federal standards for allowable exposure levels. A National Institutes of Health report shows (on page 41) that electric cars and buses have lower electromagnetic fields than conventional gasoline cars, similar to findings reported in a 1999 study by the U.S. Department of Energy.
