The fight over American energy consumption is coming to a Nascar track near you this summer.

The American Coalition for Clean Coal Electricity, an advocacy group representing coal producers, electric utilities and railroads, announced its sponsorship Tuesday of Nascar driver Dale Earnhardt Jr. and his race team, JR Motorsports.

As one of the sport’s most famous faces, Mr. Earnhardt will serve as a spokesman for the group, and JR Motorsports cars will feature the ACCCE logo, starting this week at a Nationwide series race in Richmond, Va. The sponsorship is part of a $40 million advocacy push, according to a spokeswoman for the group.
