Schools in US are huge consumers of energy. According to ENERGY STAR, K- 12 schools spend more than $6 billion every year on energy, far more than the amount spent on other resources, and at least 30 percent of this energy is used inefficiently or needlessly.
Realizing that, some schools are seeking measures to save energy in several ways, from low-cost adjustments, such as turning off lights in unused rooms, to large-scale projects, such as turning to green equipment.
As solar energy is becoming a more financial choice for powering buildings, more schools are making the move toward the renewable energy and using solar panels(太阳能电池板)on their rooftops. According to an online solar marketplace EnergySage, schools have their strong points to use solar energy. They often have the kind of enough space, suitable locations that are perfect for setting up solar panels.
In September 2020, a nonprofit Generation180 released its third edition of a study on solar use in US schools. The findings showed that more than 7, 300, or 55 percent, of K- 12 public and private schools used solar energy, the number has increased by 81 percent since 2014.
They also described how solar schools were saving millions in energy bills, and provided several cases to show the increased savings achieved by solar-powered school districts. For ex- ample, an Arkansas school district used its every year's energy savings of nearly $100, 000 to increase its teachers' salaries.
The Interstate Renewable Energy Council, which tracks the number of K- 12 schools with solar equipment and helps schools go solar, says on its website that schools with solar setups have an opportunity to educate students about clean energy, and show them that they are de- voted to do something for students' and the planet's health and future.
Third-party ownership also makes funding for 79 percent of schools to use solar energy possible, meaning a majority of schools don't have to spend large amounts of money but can get the rewards of solar energy.
