The Green Seen

Posted by: Leonard Anderson

Several items relating to the business and technology of clean energy caught our attention this week:

• San Francisco has passed a law requiring all homes and businesses to recycle and compost. Mayor Gavin Newsom says if everyone puts all the garbage, food scraps and other waste in the correct color-coded buckets, the city's recycling rate would rise to 90 percent from the current 72 percent. There's a cap of a $100 fine for homes and small businesses, but Newsom says the goal is to heighten public awareness.
• Smart Sewers? Yes, we will have them right here in San Francisco. The city's Public Utilities Commission and IBM Corp. have teamed up to install software to monitor maintenance of the city's 1,000-miles of sewer pipes and pinpoint potential water pollution, overflowing storm drains and other underground emergencies. 
• Chicago's 110-story Sears Tower, the tallest building in the Western Hemisphere, will get a $350 million "green" retrofit that aims to reduce electricity use by 80 percent and water consumption by 40 percent. The makeover will include gas boilers with fuel cells to generate electricity, heat and cooling; solar panels to heat water; wind turbines, if possible; "green" roofs; new lighting systems; and water conservation in new restroom fixtures, among other energy-saving features.
