ESTELA joins Solar Impulse Foundation

We are happy to announce that ESTLA is joining Solar Impulse Foundation to materialise climate neutrality and green transition targets for 2030 included in the EU Green Deal. The goal of this fresh initiative is to accelerate the energy transition effort and offer key policy-makers existing and ready-to-be implemented solutions at a national and local …

Margaret Hamilton popularized the term ‘software engineering’ while leading nearly 100 developers on Apollo, partly to win respect for a discipline so new it was not yet a recognised field when her team’s code helped land Apollo 11 on the Moon September 21, 2026
Margaret Hamilton was 32 and running a team of nearly 100 developers at MIT when she coined the phrase 'software engineering' — half as a joke, half as a demand for respect. Six weeks later, her team's code became the first ever to run on the Moon. The post Margaret Hamilton popularized the term ‘software […]
How did a Sahel nation facing advancing desert regrow roughly 5 million hectares of trees on farmland by changing one rule about who owns the seedlings sprouting in a farmer’s field? September 21, 2026
Over two decades, roughly 5 million hectares of Niger's degraded farmland regrew an estimated 200 million trees — not through planting, but through a change in who legally owns a sprout in a farmer's field. The post How did a Sahel nation facing advancing desert regrow roughly 5 million hectares of trees on farmland by […]
Every normally sighted human eye has a blind spot about as wide as three small coins held side by side at arm’s length, created where the optic nerve exits the retina and leaves no photoreceptors, and the brain quietly paints over the gap using whatever pattern surrounds it September 21, 2026
Every human eye has a permanent blind spot where the optic nerve exits the retina, roughly the size of a small coin at arm's length. The brain hides it by painting in whatever pattern surrounds the gap — a trick so seamless it is now being used to test theories of consciousness. The post Every […]

September/October 2026 issue: Preparing for tomorrow’s solar and storage trends October 12, 2026
How much is an electron worth? I’ve been staying inside a lot more this year because the weather in Pennsylvania has been mercurial. Frequent flash flood conditions, hazy skies from traveling wildfire smoke, sweltering heat in record breaking temperatures. I’m more familiar with the hum of central air conditioning than I’ve ever been,… […]
Solar + storage construction starts on Project Sterling in Arizona October 8, 2026
Solar and storage system construction has begun for Project Sterling in Mohave County, Arizona. ContourGlobal is building the 509-MW solar and 1.4-GWh storage project, for which Tesla has already signed a PPA. “Arizona’s sun has been shining on this land for billions of years. Project Sterling will put it to work by turning sunlight into… […]
4-hour battery storage is cheaper to install than gas turbines all across globe October 8, 2026
Wood Mackenzie’s latest global report on levelized cost of electricity (LCOE) shows that advancing technologies and market dynamics continue to drive divergent prices, with four-hour battery storage now less expensive than open-cycle gas turbines in all 43 markets where both technologies were modeled. In the Middle East and Africa, where utility-scale solar already leads at… […]
