A2: Water, Energy

By

On the blog Information Systems for Environmental Sustainability, an Ann Arbor homeowner posts information about his home’s water and energy usage: “My water meter pings the city every day, which packages and presents that data to me online. We used 86.5 gpd in the most recent period, despite reductions from one year earlier (I think we had a slow water leak last year that caused this). Time to buy a shower timer, or limit showers to 3 ipod songs, or something.” [Source]
