The Green Seen

Posted by: Leonard Anderson

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

Major league baseball spring training begins next week and the greening of the sport continues to show no letup. The Minnesota Twins are installing a giant underground storage tank the size of a freight car to harvest and recycle rainwater at their new ball park, Target Field. The Twins may save more than two million gallons of water a year. The Rain Water Recycle System will purify rainwater for human consumption as well as maintenance and irrigating the field. It was designed by Pentair, a company specializing in water systems and storage. The Twins also are seeking a LEED (Leadership in Engineering and Environmental Design) certification for the new park.

Eco-minded residents of Berkeley are recycling and composting so much that the city's refuse revenues are down by $4 million, the biggest factor in a $10 million city budget deficit. Residents are switching to smaller trash bins which carry a lower collection rate. People are buying less stuff so there's less packaging and cardboard waste, and a failed business means there's no trash to collect. "Not only does the amount of garbage change with the economy, but the very nature of garbage changes," says Robert Reed, spokesman for Recology Sunset Scavenger, San Francisco's garbage company.

Car sharing memberships in North America soared by 117 percent between 2007 and 2009, according to the Frost & Sullivan research firm, and total membership is projected at 4.4 million in North America and 5.5 million in Europe by 2016. The firm estimates that each vehicle in a car sharing fleet replaced 15 personally owned vehicles in 2009 and car sharing members drove 31 percent less than when they owned a personal vehicle. This means fewer cars on the road and a reduction of more than 482,000 tons of CO2 emissions. Meanwhile, car sharing firm Zipcar Inc. has pulled the 2010 Toyota Prius hybrids from its fleet (less than 1 percent) due to the recall for a potential brake problem. Zipcar also has removed 2009 and 2010 Toyota Matrix models in a previous safety recall.
