If every public school in the United States went 100% solar, the resulting emissions reductions would be equal to shuttering 18 coal-fired power plants. And, as one Arkansas school district recently proved, the money saved on energy costs could translate into higher pay for teachers.
The number of public school students attending schools equipped with solar panels has increased 81% since 2014, writes Climatewire, in a post republished by Energy News Network.
“In 2019, 16% of U.S. school districts (home to about 5.3 million students) had installed a total of 1,337 megawatts of solar capacity,” it the publication states. But standing in the way of that remaining 84% are “policy roadblocks, financing complications, and unease in some communities about opting for a non-traditional energy source.”
One of the policy shifts that has had the greatest effect in boosting uptake among U.S. schools has been allowing solar developers to “use power purchase agreements to finance, build, and maintain arrays on a customer’s property,” said Generation180 Program Director Tish Tablan. The approach allows a customer to pay the developer “for the energy that the panels produce over a period of time—almost always at a lower rate than it would pay the utility.”
Once installed, the solar panels have proven golden for public schools: “They’re seeing no up-front costs and immediate cost savings,” said Tablan.
At one particular site, that money is being put to good use. The solar systems and efficiency upgrades installed at a public school in Batesville, Arkansas, have “translated directly into higher wages for district teachers.”
The local school board embraced solar after a 2017 energy audit discovered that “the district’s annual utility bills surpassed US$600,000, a steep sum for a school system that for years was strapped for cash—and struggled to retain teachers as a result.”
The audit also found that the district “could save at least $2.4 million over 20 years if it outfitted Batesville High School with more than 1,400 solar panels and updated all of the district’s facilities with new lights, heating and cooling systems, and windows.” In the end, Climatewire says, the solar panels and retrofits slashed the district’s annual energy consumption and “generated enough savings to transform the district’s $250,000 budget deficit into a $1.8-million surplus.”
School Superintendent Michael Hester told Climatewire he knew immediately what he would do with the money: pump up teachers’ salaries, thereby retaining both staff and students. Educators in the district have since seen average salary increases of between $2,000 and $3,000.
The success has led at least 20 neighbouring school districts to follow suit, said Hester.
“We have the numbers to prove and to show from performance that we’re walking the walk. That’s a slam-dunk for districts around us,” he added.
it reflects extremely poorly, when Watt is mentioned as a unit of energy.
Further, the audit says the savings could be upwards of 2.4 million over 20 years. When talking about a budget , it is usually yearly. So over 3 years, a yearly budget deficit of 250.000 became a 1.8 million surplus? Not only does the scale not match, but it somehow saved almost its entire value over 20 years in 3 years.
Nice catch, Michael, thank you. I don’t have too much trouble with them projecting a 20-year saving, since it’s not unusual to build cost-saving assumptions for renewable energy installations based on the life of the equipment. But we should have caught the reference to watts, rather than watt- or kilowatt-hours, in our editing.
I’ve edited the post in a way that still reflects the original source material we were working from, but corrects the errors you’ve flagged by deleting the inconsistencies. That’s not a perfect solution — but even if the details in that original content appear to be imprecise, I’m confident in the source, and therefore still certain there’s a story here. (Beyond the specific calculations, we wanted this story in the first place because it’s brilliant to see underpaid teachers getting a boost thanks to a technology that also reduces the state’s emissions.) If anyone wants to go back to the original Climatewire post and see what we’re talking about here, the link is in the second paragraph of the story.
