Since April 2008 The Sacramento Municipal Utility District has been using peer pressure and social proof to try and get customers to lower their energy consumption by giving them information about their energy consumption compared to their neighbors and to the company’s most efficient customers. Those customers who have gotten this information have lowered their energy usage by up to 2%.

This is a very interesting example of Social Proof, where seeing how others are saving, hits the customer directly in the wallet. What a great idea.
