5,500 K-12 Schools Have Already Gone Solar

Nearly 5,500 K-12 schools in the U.S. are harnessing the sun's rays for energy, according to a new report by the Solar Energy Industries Association (SEIA), the Solar Foundation and clean energy nonprofit Generation 180. That means about five percent of all K-12s in the nation are solar powered.

The study, Brighter Future: A Study on Solar in U.S. Schools, 2nd Edition, touts that this switch to renewables has allowed schools to reduce their electricity bills, all while freeing up resources to invest in education. Roughly four million students attend such schools.


A total of 5,489 schools have a combined capacity of 910 megawatts, which is enough to power more than 190,000 homes, the study found.

Here are some notable state achievements from the Brighter Future report:

  • California leads the nation with 1,946 solar schools and a 489-megawatt capacity.
  • Nevada has the highest adoption rate, with 23 percent of schools using solar energy statewide.
  • Arizona has the most solar school capacity on a per capita basis, at 86 watts per student.

As GreenTechMedia reported, cumulative PV capacity on K-12 school buildings has increased by 86 percent since 2008. The reason behind the surge is down to dipping installation prices and new financing options. The cost of installing solar in schools has decreased 66 percent in the past seven years.

"All of the reasons why people are going solar, […] really tie back to the affordability," SEIA spokesman Dan Whitten told the website.

However, the possibility of the Trump administration's new tariffs on imported solar equipment from the Section 201 Trade Case could stymie the country's adoption of solar power.

“Injecting significant additional costs on these projects would poke holes in the very reason that people are adopting solar: That it is affordable and that it is competitive with other fuels. Artificially raising prices is never a good thing," Whitten explained.

The Brighter Future report includes case studies of the unique paths that schools took to install solar.

For instance, at Sacajawea Middle School in Bozeman, Montana, a seventh-grader named Claire Vlases led the charge and helped raised funds to bring solar to her school. Installation cost $115,000, but the solar system is expected to pay for itself in nine years.

“My favorite part about this project was that one person like me could start something small and then the project could grow and have a big impact on the community," Vlases said.

To tie-in with the release of the report, Generation 180 is launching a national Solar Schools Campaign to encourage more schools to make the transition.

The Generation 180 website includes a toolkit that provides a step-by-step advice on the process, as well as resources to assess feasibility and financing.

Climate Change and Weather Extremes: Both Heat and Cold Can Kill

By Garth Heutel, David Molitor and Nolan Miller

Climate change is increasing the frequency and strength of some types of extreme weather in the U.S., particularly heat waves. Last summer the U.S. Southwest experienced life-threatening heat waves, which are especially dangerous for elderly people and other vulnerable populations.

More recently, record-setting cold temperatures engulfed much of the country during the first week of 2018. This arctic blast has been blamed for dozens of deaths. Some scientists believe that Arctic warming may be a factor in this type of persistent cold spell, although others question this connection.

One Year Into the Trump Administration, Where Do We Stand?

By John R. Platt

What a long, strange year it's been.

Saturday, Jan. 20 marks the one-year anniversary of the Trump administration officially taking office after a long and arduous election. It's a year that has seen seemingly unending attacks on science and the environment, along with a rise in hateful rhetoric and racially motivated policies. But it's almost been met by the continuing growth of the efforts to resist what the Trump administration has to offer.

Are Microwaves Really as Bad for the Environment as Cars?

According to many headlines blared around the Internet this week, "microwaves are as damaging to the environment as cars." But this misleading information, based on a new study from the University of Manchester, hopefully doesn't make you feel guilty about zapping your next Hot Pocket.

The research, published in the journal Science of the Total Environment, found that microwave ovens across the European Union generate as much carbon dioxide as nearly 7 million cars and consume an estimated 9.4 terawatts per hour of electricity per year. Okay, that sounds like a lot. But also consider that there are about 130 million microwaves in Europe and some 291 million vehicles on its roads.

Monsanto's Roundup Destroys Healthy Microbes in Humans and in Soils

We're only beginning to learn the importance of healthy gut bacteria to our overall health—and the relationship between healthy soil and the human microbiome.

We know that the human microbiome, often referred to as our "second brain," plays a key role in our health, from helping us digest the food we eat, to boosting our brain function and regulating our immune systems.
