Federal Energy Department highlights energy efficiency at Oklahoma City school

An energy efficiency effort at Oklahoma City’s Harding Charter Preparatory High School has been highlighted by the federal Energy Department.

The department said Harding took advantage of funding from the State Energy Program to upgrade light bulbs, put in a new heating and air conditioning system and replace older entry doors with new energy-efficient models.

Energy-efficient upgrades to Harding Charter Preparatory school are expected to save nearly 2 million kWh of electricity and more than 1,000 MMBtus of natural gas annually — reducing the school’s energy costs by about $45,000 a year.
