Solar ERoEI Is Actually Really, Really Good

The terms “energy payback” and “energy payback period” when used to discuss solar power might be kind of confusing at first glance, but when you dig a little deeper, you get much more clarity. Energy payback refers to the amount of energy a solar power system has to make in order to equal the energy which was used to produce it. Most solar panels are made up of solar cells which are manufactured from silicon. This non-metal element must be processed in order to be usable in solar cells. The processing consumes some energy, as does the assembly of solar cells into solar panels.

Car Gangsters: Should We Support Their Evolution Despite Their Mafia Past & Present?

Credit to the CleanTechnica reader who used the email subject “car gangsters” when he sent along news of ethically sketchy German auto industry “research.” Aside from the catchy phrasing, the astoundingly immoral approach that was employed on so many levels to deceive and harm society brought me back to a question that often pops into my head: Should buyers support car gangsters’ efforts to change their ways and offer electric cars, or should we just support companies that are “all in” on clean transport?

Tesla vs Bolt … China’s HUGE 2017 Electric Car Sales … Renault Zoe Wins Europe…

The hottest CleanTechnica story of the past week was, no surprise, a Tesla-related story.

I imagine you’ve already read it, but have a gander if not — at least for the pics!
