SAN DIEGO • A biofuels lobbying group says it wants to work with the oil industry to fight the threat to both from subsidies for electric vehicles.

The two industries have been at loggerheads for years as they seek to influence federal regulators over how much biofuel should be included in gasoline and diesel.

But that enmity is thawing as the growing number of electric cars on the road threatens to cut demand for both renewable and conventional fuels.

The two groups are more aligned on many objectives than they have previously acknowledged, Renewable Fuels Association (RFA) President Bob Dinneen said on Tuesday, noting electric vehicles as one area where both sides have concerns.

"We want to make sure there's a level playing field," Dinneen told reporters on the sidelines of an annual meeting.

The RFA sees opportunity to work on key regulatory and other issues with Big Oil, he added.

"Our objectives will align more times than not," Dinneen said to two representatives from the petroleum industry on a panel.

Oil advocates agreed that electric vehicles are cause for concern to the transportation fuel sector.
