Reservoir Hill writes "In a demonstration project in Washington State, 112 homes equipped with digital thermostats and computer controllers attached to water heaters and clothes dryers were connected to the Internet so homeowners could monitor energy consumption constantly. The homeowners could go to a Web site to set their ideal home temperature and how many degrees they were willing to have that temperature move above or below the target allowing them to decide the trade-off they wanted to make between cost savings and comfort. The households in the demonstration project on average saved 10 percent on their monthly utility bills. "I was astounded at times at the response we got from customers," said Robert Pratt, the program director for the project. "It shows that if you give people simple tools and an incentive, they will do this.""
