• The problem of solar panel disposal “will explode with full force in two or three decades and wreck the environment” because it “is a huge amount of waste and they are not easy to recycle.”

Were these statements made by the right-wing Heritage Foundation? Koch-funded global warming deniers? The editorial board of the Wall Street Journal?
None of the above. Rather, the quotes come from a senior Chinese solar official, a 40-year veteran of the U.S. solar industry, and research scientists with the German Stuttgart Institute for Photovoltaics.
With few environmental journalists willing to report on much of anything other than the good news about renewables, it’s been left to environmental scientists and solar industry leaders to raise the alarm.
“I’ve been working in solar since 1976 and that’s part of my guilt,” the veteran solar developer told Solar Power World last year. “I’ve been involved with millions of solar panels going into the field, and now they’re getting old.” ...
