Kudos to the Minneapolis-St. Paul International Airport. Minnesota’s largest solar power project is now generating electricity atop two parking ramps at the airport.

The three-million-watt system containing 8,705 solar panels went online December 1, and is expected to supply 20 percent of the electricity used in Terminal 1 and cut carbon emissions by nearly 7,000 tons per year, according to airport officials.

The $20 million solar project is the first of two at the airport. The commission recently approved a plan to install a 1.3 million-watt solar array atop a parking ramp at Terminal 2, at a cost of $8.5 million. Construction is expected to begin this year.
