Originally published on Planetsave.com. The Union of Concerned Scientists’ Clean Vehicles program recently released an updated version of its rather comprehensive “backgrounder” on electric vehicles — “how much the technology is growing in the country, the opportunities it presents for consumers and automakers, and the challenges facing its adoption,” to … [continued]
Following up on two articles about my tour of Activ Solar’s Perovo Solar Power Station in Crimea, Ukraine, below is a lengthy interview with the COO of Activ Solar* that I found particularly interesting and fun to conduct. Activ Solar is currently the 3rd-largest utility-scale solar developer in the world … [continued]
Remember the man who gathered $32,400 to attend a Democratic National Committee fundraiser? He wanted 2 minutes to tell the president some things about electric vehicles. That man, occasional CleanTechnica guest author Paul Scott, was uninvited from the fundraiser and refunded the money (which actually came from his retirement fund). … [continued]
Originally published on EV Obsession. Oftentimes with filters, limits, or intellectual boundaries, they say there is a line to walk.
