The Department of Energy reports that taxpayers spend $6 billion on energy costs for K-12 schools each year. This is more than what is spent on textbooks and computers combined, and it’s the second highest expenditure after salaries.
Due to the inefficiency of current systems, school energy costs are estimated at about 25% more than what is actually necessary for daily operation. According to SchoolEnergySaving.com, the average school building in the United States is 42 years old. These aging buildings were not designed with today’s student population in mind. Modern technology has significantly increased the energy loads a school must meet.
In Brighter Future: A Study on Solar in U.S. Schools Report, the Solar Energy Industries Association states that there are 3,752 K-12 schools in the United States with solar installations. The electricity generated yearly from these systems represents a combined value of $77.8 million. This combined value is enough for nearly 2,200 new teachers’ salaries or 155,000 tablet computers for classroom use.
School energy use is divided as follows:
• Lighting: 26%
• Cooling: 26%
• Office equipment: 20%
