Citizens for Responsible Energy Solutions (CRES) has announced a slew of advertising in support of lawmakers advocating for clean energy solutions in the U.S.

The group, which describes itself as a nonprofit advocating for comprehensive and responsible solutions to the U.S.’ energy issues, has launched TV and radio ad buys in Nevada and Iowa, as well as continued radio advertising in Alaska.

Specifically, the group is applauding Rep. Joe Heck, R-Nev.; Sen. Chuck Grassley, R-Iowa; and Sen. Lisa Murkowski, R-Alaska, for their leadership in support of clean energy solutions in Congress.

CRES says it spent $155,000 on the TV and radio ads in Reno, Nev., and $106,000 on the radio ads in Des Moines and the Quad Cities in Iowa. The statewide radio ad buy in Alaska represents a continuation of a $110,000 ad spend launched recently.

In addition to these ads, CRES says it has spent $710,000 supporting candidates and committees in 2016. The group is aiming to aggressively support Republican House and Senate candidates who speak out in support of commonsense, clean energy solutions on the campaign trail and Capitol Hill.

“More than seven in 10 voters are more likely to vote for a congressional candidate that supports an agenda that promotes the diversification and growth of clean energy resources like wind, nuclear, solar and hydropower,” stated Andrew Bird, the group’s director of federal affairs.

“In addition to achieving substantive progress in advancing clean energy technology on Capitol Hill, CRES remains firmly committed to ensuring that voters demanding action in support of renewable energy are familiar with the records of clean energy champions who place results and good policy before partisanship in Washington.

“We stand firmly behind elected leaders focused on supporting clean energy policies that grow the economy, strengthen our national security and preserve our environment for future generations,” he said.
