Why solar power is taking over the world

By Stephanie Pappas , Scientific American. Excerpt: Forty-seven years ago U.S. President Jimmy Carter stood grinning in front of a set of 32 bulky solar panels. It was 1979, and the oil crisis had sent fuel costs skyrocketing. Carter, in response, was making the White House an example of conservation and alternative energy. “Solar energy will not pollute our air or water,” he said. “We will not run short of it. No one can ever embargo the sun or interrupt its delivery to us.” ...Even before the U.S.-Iran conflict closed the Strait of Hormuz for months, causing fossil-fuel prices to spike, solar was soaring. Last year the world added 600 terawatt-hours of solar photovoltaic generation, enough to power Canada for a year. It was the first time that a renewable source took the top slot in global supply growth. It was also the largest single-year increase for any electricity-generation technology, according to the International Energy Agency (IEA). ...Solar Is Now the Cheapest Way to Produc...

Full article at Solar Farms Are Having An Unexpected Effect On An Endangered Species

By Noelle Corbett, BGR.  Excerpt: In addition to supplying clean energy, solar panels have a surprisingly positive impact on degraded land and local wildlife . The panels block the sun, allowing the soil to retain more moisture to the point where China's largest solar farm is changing the desert around it , turning a once dry landscape green with plant life. Animals can also benefit from solar farms, including the San Joaquin kit fox, an endangered species that lives in central California, whose population faces many threats, including habitat loss and predators. ...Researchers examined how the facilities impacted local foxes in two separate studies carried out from 2014–2017, with results published in a 2019 report .... They found that solar farms' fences kept out common predators like bobcats and coyotes, animals too large to fit underneath. Additionally, the solar panels provided shielding from birds of prey like the golden eagle.... Another study carried...out between 2019 ...

Most big US solar projects don’t spark backlash after all, study finds

By Michelle Lewis , Electrek.  Excerpt: Despite the impression that large solar farms are constantly sparking local fights, a new study from researchers at the University of Massachusetts Amherst found that most large-scale solar projects in the US move forward with relatively little public opposition. The study, published in the journal Energy Research & Social Science , looked at 686 utility-scale solar projects that came online between January 2022 and November 2023. Researchers found that 56% of the projects fell into “no” or “low” conflict categories, while just 19% experienced high levels of conflict. ...Researchers also found that utility-scale solar projects approved through state-level permitting systems tended to face less conflict than those reviewed under local or hybrid permitting systems. However, Katz cautioned that the study shouldn’t be interpreted as proof that state-level permitting systems are automatically better than local review processes. Instead, she sa...

Power to the people: how ‘balcony solar’ could help fight rising US utility costs

By Ben Tracy of Climate Central .  Excerpt: ...Unlike traditional rooftop solar, which requires thousands of dollars in upfront costs, specialized mounting hardware and professional electricians, this system is designed for the everyday consumer. It’s a $400 kit from Bright Saver, a non-profit advocating for “plug-and-play” solar that works for renters and homeowners alike. The setup is deceptively simple: you hang the panel on a balcony or prop it up in a back yard and plug it directly into a standard wall outlet. ...While these panels won’t take a home entirely off the grid, Stryker says the units can trim monthly costs by 10% to 25% depending on how many panels a user installs. More savings can be had if the panels are paired with batteries that can store excess solar energy. “They cover a part of your energy bill and then you do need to draw the rest from the grid as you do now,” Stryker said. While the technology is just gaining a foothold in the US, it is already a cultural p...

Solar ranch in Tennessee aims to prove grazing cattle under the panels is a farmland win-win

By TAMMY WEBBER  and  JOSHUA A. BICKEL , Associated Press.  Excerpt: CHRISTIANA, Tenn. (AP) — From a distance, the small solar farm in central Tennessee looks like others that now dot rural America, with row upon row of black panels absorbing the sun’s rays to generate electricity. But beneath these panels is lush pasture instead of gravel, enjoyed by a small herd of cattle that spends its days munching grass and resting in the shade. Silicon Ranch, which owns the 40-acre farm in Christiana, outside of Nashville, believes cattle-grazing is the next frontier in so-called agrivoltaics, which mostly has involved growing crops or grazing sheep beneath the panels. The solar company debuted the project this week and will spend the next year working to demonstrate to farmers that much larger cattle also can thrive at solar sites. If successful, advocates say, that could jump-start new projects to meet the soaring electricity demand driven by rapidly expanding data centers — with...

‘Yes to fields of wheat, no to fields of iron’: how the world’s greenest country soured on solar

By Ajit Niranjan , The Guardian.  Excerpt: In one telling of the story, the golden fields of a proud farming nation are under attack. Besieged by an industrial sprawl of solar panels, they are being smothered at the behest of an urban elite. That narrative has failed to thrive in conservative heartlands such as Texas and Hungary, which have embraced solar power while lambasting green rules. But it is taking root in  Denmark , the most climate-ambitious nation on Earth. “We say yes to fields of wheat,” said Inger Støjberg, the leader of the rightwing populist Denmark Democrats in a speech in 2024. “And we say no to fields of iron!” ...in Denmark, which generates 90% of its electricity from renewables and aims to  cut planet-heating pollution  faster than any other wealthy country, the spread of solar power has alarmed some regions in which construction is concentrated. Solar tripled from 4% of Danish power production in 2021 to 13% in 2025. And a handful of villages h...

Why farmers in California are backing a giant solar farm

By Dan Charles , NPR.  Excerpt: A  mammoth solar farm  is moving forward in the heart of California. If built, which seems increasingly likely, it would cover 200 square miles of land and generate 21,000 megawatts of electricity, enough to power entire cities. Huge batteries will store some of that power until it's needed most. Farmers are among the project's backers. They don't have enough water to grow crops on big chunks of their land, and they're looking for new uses for it. "We're farmers, and we would rather farm the ground," says Ross Franson, president of Woolf Farming and Processing, his family's business. "If we had the water to do it, we would farm it. But the reality is, you don't. You have to deal with the cards you're dealt."...  Full article at https://www.npr.org/2026/02/26/nx-s1-5726411/farmers-california-san-joaquin-valley-solar-farm-westlands-water-district-golden-state-clean-energy .

Cheap Solar Is Transforming Lives and Economies Across Africa

By Somini Sengupta , The New York Times.  Excerpt: Solar has risen from almost nothing in 2019 to roughly 10 percent of South Africa’s  electricity-generating capacity . ...No longer do South Africans depend entirely on giant coal-burning plants that have defined how people worldwide got their electricity for more than a century. ...Joel Nana, a project manager with Sustainable Energy Africa, a Cape Town-based organization, called it “a bottom-up movement” to sidestep a generations-old problem... unreliable electricity, expensive electricity or no electricity at all,” ...South Africa was the largest destination for Chinese solar, but not the only one. Sierra Leone imported the equivalent of more than half its total current electricity-generating capacity, and Chad, nearly half. ...Chinese state-owned companies are among several international firms to bid on South Africa’s $25 billion grid expansion, vying to build the lines and then make money, in part, by operating them........

ERCOT’s Market is Transitioning Toward Storage and Solar

By Arcelia Martin , Inside Climate News.  Excerpt: Capacity additions to the Texas grid continue to be led by renewables. Battery storage facilities and solar farms powered virtually all capacity growth in Texas’ electric grid throughout 2025, as the home of the nation’s oil and gas industry created almost twice as much new solar power as California. ...according to the Electric Reliability Council of Texas (ERCOT), operator of Texas’ electric grid...Solar power accounted for the second-largest capacity addition, with more than 4,500 megawatts installed....  Full article at https://insideclimatenews.org/news/10122025/texas-electric-grid-transitioning-to-battery-storage-solar/ .

Renewable energy and EVs have grown so much faster than experts predicted 10 years ago

By Adele Peters , FastCompany.  Excerpt: Most climate reports are bleak. Temperatures are soaring. Sea levels are rising. Companies are missing—or abandoning—their emissions targets. But a  new report  from the nonprofit Energy & Climate Intelligence Unit (ECIU) looks at the surprising amount of progress that’s happened since the Paris climate agreement 10 years ago. Renewable energy has grown faster than every major forecast predicted in 2015. There’s now four times as much solar power as the International Energy Agency (IEA) expected 10 years ago. Last year alone, the world installed  553 gigawatts  of solar power...which is 1,500% more than the IEA had projected. Investors are now pouring twice as much into renewables as into fossil fuels. More than 1 in 5 new cars sold worldwide today is  an EV ; a decade ago, that number was fewer than 1 in 100. ...the world is on track to reach 100 million  EVs  by 2028. Dozens of countries have net-zero...

China Is Leading the World in the Clean Energy Transition. Here's What That Looks Like

By Antonio Piemontese , Wired.  Excerpt: Speaking by video  at the UN Climate Summit in New York last week,  China's  president Xi Jinping laid out his country's  climate  ambitions. While the stated goals may not have been aggressive as some environmentalists would like, Xi at least reaffirmed China's green commitment. “Despite some countries going against the trend, the international community should stay on the right track, maintain unwavering confidence, unwavering action, and undiminished efforts,” he said. Any reference to Donald Trump and the United States was surely intended (though not explicit). ...Xi Jinping's speech included a commitment to reach 3,600 gigawatts (GW) of installed wind and solar capacity by 2035, six times the country's 2020 figures. This is already the leading country in terms of installed renewable power, and a giant on the technology front as well, with universities churning out environmental and climate tech research at full ...

Is This L.A. Home the Solution to America’s Growing Energy Crisis?

By Ivan Penn  and  Malika Khurana , The New York Times.  Excerpt: U.S. electric grids are increasingly under strain and utility companies are spending tens of billions of dollars on upgrades — expenses that are driving up electric bills. At the same time, power-hungry data centers, electric vehicles and heat pumps are increasing demand for electricity. ...One solution is to install more rooftop solar panels and batteries. Each such system is small, but collections of them can act like small power plants by supplying electricity to the grid when demand surges on, say, summer afternoons. ...“Putting on solar without a battery, does almost nothing to help” the energy system, Mr. Borenstein, the Berkeley professor, said....  Full article at https://www.nytimes.com/interactive/2025/09/27/business/energy-environment/rooftop-solar-panels.html .
