Hotels are known as energy wasters, generating large amounts of water and electricity to serve their customers. But one hotel entrepreneur is trying to change that by going green. In this video, correspondent Sumi Das meets Wen Chang, founder of the Gaia Hotel in the Bay Area's Napa Valley. He believes hotel owners can do more to help the environment, without hurting the bottom line. According to Chang, the Gaia Hotel is saving $50,000 to 75,000 dollars a year on electricity by using clean energy to power 12% of its operations.
