The article paints a rosy picture: that solar and wind is basically taking over, that most new capacity installed in the U.S. and U.K. is now PV and wind, that even the World Bank and big investors have come on board, despite backward and myopic government policies that promote fracking and subsidize fossil fuels. All true, but there is a dark side that I wish had been mentioned.
First, I'd like to see mention of the environmental problems that come with PV -- the hazardous waste generated in PV panel production and the eventual disposal of dead panels. Second and more important is the fact that the increasing share of renewables in the energy production mix won't help if, at the same time, total energy production from all sources continues to rise at the same rate.
It isn't my habit to nitpick at articles that I feel basically aligned with. Maybe it was just the rosiness of the picture it paints triggers me -- so used to bad news, am I afraid to hear the good news? I feel wary.
