Christina Page, Director of Climate and Energy Strategy at Yahoo!, is tasked with reducing the footprint of a website network that serves more than 600 million users. “We really ‘walk the talk’ as much as we possibly can,” Page says. “Yahoo! Green is the number one green-content website on the Web right now. There is great green content to be found on virtually all Yahoo! properties.” Page has overseen Yahoo!’s data centers become increasingly more efficient. She claims that Yahoo!’s data centers are 40% more efficient than the competition, use 90% less water and cost far less than most others. The amount of water saved in Yahoo!’s eco-friendly data centers is enough to provide drinking water for approximately 200,000 people for a year.
