The Abercrombie administration has unveiled an energy efficiency program for the Department of Transportation’s Airports Division that it claims will cut energy use by 49 percent, saving $518 million in energy costs over the next 20 years.

The airports, according to a press release, will be modernized “with the latest in energy-efficient and green technology.”

The project will replace 372 transformers and 74,500 light fixtures, install 9,100 solar photovoltaic panels and include upgrades and replacement of chilled water and air conditioning systems and installation of smart controls.
