Add two more baseball teams to the list of professional sports organizations choosing to go with renewable energy for their home stadiums. Both the St. Louis Cardinals and the Kansas City Royals have installed rooftop solar arrays in time for the 2012 season, joining six other teams that have done the same in the last few years.

At the Cardinals’ Busch Stadium in St. Louis, Microgrid Energy installed 106 solar panels on the roof of Ford Family Plaza. It will produce 32,000 KW of electricity each year, generating enough energy to cook four million hot dogs. And while that may not be the best use of a solar installation ever devised, it’s certainly a good place to start at a baseball stadium to reduce grid-based energy consumption. Vice President of Stadium Operations Joe Abernathy said that the solar array is part of the team’s commitment to going green and that “since the stadium opened in 2006, we’ve been able to cut our energy use by 20 percent and water use by 10 percent.”

Over in Kansas City, Royals’ Kauffman Stadium has the largest in-stadium solar array in Major League Baseball. It is a 28.8 kilowatt array made up of 120 solar panels capable of generating 36,000 KW of electricity every year. That’s enough energy to refrigerate all the concession beverages in the stadium prior to sale to attendees.

The Cardinals and the Royals join six other teams – the San Francisco Giants, Seattle Mariners, Cleveland Indians, Boston Red Sox, Arizona Diamondbacks, and the Colorado Rockies – in installing solar arrays which will partially power some part of their stadium. Upcoming seasons should see even more MLB teams going green, as a partnership with the NRDC started back in 2005 is in place in order to help all teams pursue more eco-friendly operations.
