The first, an item from the Philadelphia Inquirer, notes that PNC Bank, the nation's 20th largest bank, has opened 43 environmentally friendly, or "green," branches since 2002 with many more on the way. PNC officials would not say how much they spend on green branches, but said it had spent $100,000 less than an unspecified competitor spends on conventional branches.Meanwhile a data center energy meeting in Boston this week attended by a variety of large users and vendors such as IBM, EMC, AMD and HP said data center designers and operators often fail to take advantage of existing technology and design principles that could greatly reduce power consumption. The average data center probably uses three times more air conditioning and cooling than is needed. http://www.networkworld.com/community/node/18444"
