The political action arm of a conservative clean energy group is endorsing two New York Republicans on Thursday in a bid to boost their chances of re-election.

The ClearPath Action Fund announced Thursday it is endorsing two conservative clean energy champions, Reps. Tom Reed and Elise Stefanik, in their respective races to keep their seats.

"Tom and Elise are independent leaders who work across the aisle to enable the development of clean energy, which creates jobs and lowers costs," the group's founder and CEO Jay Faison said in a statement.

"Their continued leadership is critical to ensuring that we move ahead with a sensible, affordable and diverse set of existing power sources, as well as make the necessary investments to foster innovation that will create the next generation of clean energy power," he said.

The ClearPath Action Fund, and the affiliated ClearPath Action, are 501(c)4 advocacy organizations focused on advocating for lawmakers that support clean energy. The groups plan to inject $5 million into this election year "promoting a select group of conservative clean energy leaders."

The endorsements will be followed by a six figure ad buy supporting the candidates. The ad campaigns will include digital buys on Facebook, Google, Twitter, YouTube and 4info.

ClearPath Action will also be rolling out a larger ad buy in two Republican Senate races for Sens. Rob Portman of Ohio and Kelly Ayotte of New Hampshire. It had endorsed the candidates in April. Portman has been a strong supporter of energy efficiency and nuclear power, and Ayotte has supported energy efficiency and biomass-based power plants that burn pelletized wood waste to produce electricity with lower emissions.

In addition, the group will also be setting up websites for the candidates to detail their energy records, including: RobForCleanEnergy.com and KellyForCleanEnergy.com.

"Not only do I intend to help re-elect Senators Portman and Ayotte, but we're going to build a new model for winning in the Republican Party," Faison said back in April when he endorsed the senators. "I continue to believe that clean energy is an issue that Republicans can rally behind and will help our party move forward."

It's been a busy week for the fund. On Tuesday, it issued its first U.S. House endorsement for Rep. Carlos Curbelo of Florida's 26th congressional district.

Faison's separate ClearPath Foundation has been pushing support for a Republican clean energy platform that includes nuclear, hydropower, natural gas and energy innovation.

Faison has been working with the Republican National Committee to include a clean energy plank as part of the GOP platform in the runup to next month's convention in Cleveland.
