Read my complete post on The Scholarly Kitchen. Excerpts:
Hohm is a Microsoft home energy monitoring software available in beta since July 2009. The premise is straightforward — consumers complete an individual energy profile online and agree to let Microsoft access their current and historical data from participating utility providers (the first to partner with Hohm were Xcel Energy, Sacramento Municipal Utility District, Seattle City Light, and Puget Sound Energy). Via the information that consumers supply and these utility-provided datafeeds, Microsoft acquires detailed data about on-site usage of heat, cooling, lighting, appliances, water heaters — even electric cars.
The proposed consumer value is that Microsoft will monitor your energy use to provide dashboard-like reports analyzing your household consumption and energy use and make recommendations for system or practice modifications that will result in lower energy use and cost savings.
As with all things in the hot-and-getting-hotter showdown between Google and Microsoft, that’s not the end of the story. Paul Miller on Engadget mentions the competitive offering from Google, the PowerMeter API. And, just days ago, MicroChip announced that has partnered with Google PowerMeter to release a more developer-friendly Reference Implementation that will “make it much easier to create products that are compatible with Google PowerMeter.”
