The U.S. Energy Information Administration Annual Energy Outlook report for 2014 predicts that by 2040, nearly eight in 10 cars sold will run on gasoline, down marginally the number sold last year. The number of diesels rolling out of showrooms will double to 4 percent of all vehicles sold, while hybrids will comprise 5 percent of cars. That’s up from 3 percent last year.

But the headline figure is this: The EIA predicts that only 1 percent of total vehicle sales in the U.S. will be plug-in hybrids, with another 1 percent being fully electric in 2040.

“The numbers of LDVs [light duty vehicles] powered by fuels other than gasoline, such as diesel, electricity, or E85, or equipped with hybrid drive trains, such as plug-in hybrid or gasoline hybrid electric, increase modestly from 18 percent of new sales in 2012 to 22 percent in 2040,” the report states.
