Setting himself up for countless "hot air" punchlines, Gavin Newsom "is calling for windmills throughout the city," reports KCBS. An estimated 29 of them might pop up in SF sometime in the very near future. Or not. (Although he'd like to "streamline the permit process" to get them up ASAP.) Anyway, Newsom goes on to said that the wind turbines cold be put on historical landmarks. he also emotes, "wind is a rural or suburban phenomenon and not necessarily an urban phenomenon ... We believe wind needs to be part of the urban mix of renewables. Our goal is to have 50 megawatts of renewable energy being generated within the city and county of San Francisco over the next few decades."
