My interest in interactive wireless sensor networks has been growing over the past several months. This technology supports how we will interact with our "things" in the world. It sounds futuristic, but the technology is here and is in the implementation stage in Boulder, Colorado, known as SmartGrid City.
There are some issues facing the usability of this system for homeowners who participate in the SmartGrid City project. Here is an example from an article in the Wall Street Journal:
"...The Petersons' experience with the smart grid has not been entirely smooth. Mrs. Peterson says it can be cumbersome -- and "boring" -- to use the smart-grid Web site to manage her home's energy use. She has to set more than a dozen data points just to get her bedroom temperature where she wants it through the week.
Her husband finds some of the online charts that track his home's energy use too abstract. "If I told you that today you saved four pounds...of carbon emissions, what does that mean to you?" he asks. He prefers when the software serves up analogies he can visualize: He's saved enough energy to microwave 9,550 frozen pizzas or to light a major-league ballgame for three innings."The system, of course, was designed by engineers, right?
If you click on the graphic below, you will link to an interactive graphic from the Wall Street Journal that gives a good visual overview of a house that is linked to the SmartGrid City:
"SmartGridCity is the nation's first fully integrated smart grid community and will boast the largest and densest concentration of these emerging technologies to date."
