“The newest wind turbines gracing the naction’s countryside actually are turning more slowly than their older cousins. The languid pace is the most visible consequence of new-generation wind turbines that are taller, have longer blades, capture more wind and produce more power.” Austin Daily Herald
The Guardian reports on a new report outlining the promise and challenges facing wind energy development.
“Wind energy could provide 20-100 times current global power demand, according to a study published this week in Nature Climate Change. Other studies have shown similar results, but they do not mean that wind power is all we will ever need, says Ken Caldeira of Stanford University’s Carnegie Institution, and co-author of the new study.’We’re always going to need a variety of energy sources,’ Caldeira told the Guardian. Nor does it mean installing enough wind turbines to power the world is practical or even feasible. There are significant technical and resource problems to overcome, not least of which is finding the money to construct millions of turbines, he acknowledged.’It’s a huge scale-up … but not unimaginable. The reality is this is what the global energy generation is right now.’” (Guardian)
