According to findings describe in prior installments of reports on the Climate Insights 2020 survey of American public opinion, large majorities of Americans believe that the earth has been warming over the past 100 years; that this warming will continue in the future if unaddressed; that it will constitute a nationally and globally serious problem; and that governments, businesses, and individuals should take steps to curb this warming and its likely effects.

According to some natural scientists and economists, one potential step to reduce emissions and mitigate climate change would be the widespread adoption of all-electric vehicles (EVs), which can be powered by electricity generated by sunlight, wind, and water. According to the US Environmental Protection Agency (see below), transportation emits more greenhouse gases than any other sector in the US, attributable to transportation’s near-complete dependence on fossil fuels. Thus, emissions can be dramatically reduced by widespread adoption of EVs. Perhaps partly for this reason, manufacturing and sales of EVs have been increasing in recent years. Still, thus far, such sales represent a small share of consumer automobile purchases in the United States.
