According to an analysis from Environment America and Frontier Group, permitting requirements can add a whopping $7,000 to the cost of a rooftop solar power system. $7,000?! That’s a crazy amount of extra money to add onto a solar power system just to get a permit. The good news in … [continued]
"For the manufacturing process of perovskite-silicon tandem solar cells, Fraunhofer ISE focuses on the so-called “hybrid route,” a combination of vacuum and wet chemical processes."
The idea of putting solar panels on vehicles has been around for decades. I can’t say how many companies I’ve seen come and go that planned to produce and sell solar-powered cars. It’s just not the safest and most efficient place to deploy solar panels. However, I’ve never really seen … [continued]
The Denza Z was the big news this week from the 408th monthly MIIT regulatory filings. The sports car has a 500 kW motor on the front axle and two 340 kW motors on the rear axle for a total of 1180 kW (1582 horsepower). 0-100 km/h has previously been … [continued]
Ingmar Rentzhog of We Don’t Have Time wrote recently that investors have already begun the transition to clean energy.
2026 Tesla Model Y with HW4 and FSD V14. As suggested in the upper left: Tap the brake and then push the blue Start Self-Driving button or push the right scroll wheel and off you go. In this case, the car then automatically left my garage. June 11, 2026. Photo by Fritz Hasler.
I lived through almost 7 years of numerous releases of Tesla’s Full Self Driving (FSD) as it progressed in my 2019 Model 3 using “Hardware 3” (HW3), finally reaching FSD V12. Elon Musk promised every year that all of us Tesla owners with HW3 would see Level 4 self-driving in … [continued]
Tesla has gotten “Full Self Driving (Supervised)” approved in another European country. Following the Netherlands, Lithuania, Estonia, and Denmark, the driver-assist system is now allowed to be deployed in Belgium. Well, Tesla still has to pass some tests with it, and then it can be rolled out to customers, but … [continued]
ICE model sales crash 39% in May High gas prices and a never ending wave of new models has allowed May to reach record EV market share, with plugins reaching a record 63%! However, while record market share was achieved in the past thanks to strong EV sales, this time, … [continued]
The updated aviation fuel-service projection starts from post-COVID recovery, then bends liquid-fuel growth through regional-electric displacement, constrained SAF and demand pressure.
Aviation is one of the harder transition sectors to model well because it invites two bad shortcuts. One is to assume that flying keeps growing as it did in the cheap-kerosene era, with a cleaner molecule somehow dropped into the same demand curve. The other is to assume that decarbonization … [continued]
New solar PV module efficiency record from III-V germanium PV module — 34.4% efficiency. © Fraunhofer ISE / Photo: Daniel von Kutzleben.
The Fraunhofer Institute for Solar Energy Systems (ISE) is no stranger to solar power records, and it’s just set another one. Via its own III-V germanium solar PV module, the institute reached 34.4 percent solar module efficiency. The solar record march goes on. “The solar cells were developed by AZUR … [continued]
While the US is languishing thanks to permitting hell, the UK is looking to speed up its clean energy transition with faster grid connections for solar, wind, and battery projects. “Britain has offered grid connections to more than 700 projects, the country’s power planning body said on Wednesday, under a … [continued]
