Two new solar arrays on Phoenix city garages were celebrated Wednesday with a City Hall rooftop view and a visit from the U.S. Environmental Protection Agency administrator.The newest solar projects, totaling 1.18 megawatts, are Phoenix’s latest investment to reducing greenhouse gas emissions by 15 percent by 2015, a new goal set Tuesday by the city council after exceeding its original 5 percent goal. The city is now about halfway towards that goal.
