By Ryan Austin Swiss company Insolight has created the most efficient concentrating photovoltaic solar panels (CPV), a technology that uses lenses to concentrate light onto small solar panels underneath, to date. After two years of research, its created a CPV panel that achieved 29% efficiency, verified by the Universidad Politécnica de Madrid. Today’s conventional rooftop…
By Charles W. Thurston An R&D team at Fraunhofer ISE has unveiled a new solar cell stringing machine that can boost cell performance 2% by using electrically conductive adhesives to fix solar cells to a foil substrate in a shingled pattern. The process reduces the number of manufacturing steps that soldering a connective ribbon would…
By Michelle Froese DTE offered its first green bonds in May 2018. DTE Electric recently issued its second offering of green bonds. The $650 million in bonds will finance green investments, including renewable energy and energy efficiency. In its initial green bond offering in May 2018, DTE became the fifth investment-grade energy company in the…
By [email protected] (Eric C. Evarts) Falling reliability costs the Tesla Model 3 its Consumer Reports recommendation. Could high-speed rail be replaced with high-speed highways? Volvo is pulling depleted batteries out of electric buses to use as energy storage for solar in a large apartment complex in Sweden. Argonne National Lab has developed a smaller, lighter,…
By Charles W. Thurston A novel combination of high-grade spacecraft solar cell material and advanced light-concentrating lenses has yielded solar panels with a record 29% efficiency that may become available for general rooftop use by 2022. The crux in the commercialization of the planar optical micro-tracking technology will be cost-controlling manufacturing process, which is the…
By Pat Remick California has laid a strong foundation for energy efficiency in new buildings. Now the state needs to figure out how to help the entire building sector meet a carbon-neutral future by 2045. A new report offers a five-point path forward, addressing barriers that have held back progress toward clean energy homes and…..

By Nicolas Zart Electric vehicles (EV) and gas cars are not very efficient in cold weather. But while we’ve grown to blindly accept the limitations of traditional cars, EVs are still misrepresented, especially when it comes to cold weather. It’s time we nip that myth Read Full Article Here For more great articles: Clean Technica
By Clare Taylor With rising GDP, the European Union is once again at risk of missing the 2020 targets for energy efficiency, and yet more ambitious targets for 2030 lie ahead. Regulation, especially for energy efficiency in buildings, is already driving demand, according to the European Investment Bank, with commercial banks acting as aggregators. Peter…
By [email protected] (Bengt Halvorson) In just one model year, Kia has more than doubled the rated driving range for the Soul EV. The 2020 Kia Soul EV, which is expected to reach dealerships this spring, will go 243 miles on a charge—four more miles than the Kia Niro EV—according to the EPA, in ratings that…
By [email protected] (Eric C. Evarts) It turns out there’s more than one way for automakers to meet fuel-economy targets. One is to develop and sell more fuel-efficient cars and trucks. The other—as demonstrated over the years by quite a few automakers—is to pay fuel economy fines to the U.S. Treasury as a course of doing…
