Energy expert Paul Scheckel and Kevin discussed ways to monitor energy usage around the house. The whole-house electrical monitoring system that uses the internet to provide a "dashboard" showing electrical usage is manufactured by: eMonitor by PowerHouse Dynamics

From virtually nothing in 2000, the industry today can boast 1.5 GW of installed offshore wind capacity, of which 334 MW – more than one fifth – was installed in 2008 alone, see Figure 1, (below). An additional 1.5 GW is currently under construction, and Douglas-Westwood forecasts more than 5 GW will be in the water by 2012.

Materials
- Current Transducers - $46.00 for 2
- Arduino Diecimilia Microcontroller ~ $20
- Arduino Ethernet Shield ~ $45
- Small sheet plexiglass with mounting screws and standoffs ~ $5
- Router capable of running openwrt or something can serve a cgi script (optional) ~ $40
- Web server to host the power charts (optional) ~ $5/month
Total cost ~ $110 (not counting what I already had lying around) If money is tight there are a few things that can make this cheaper by about fifty bucks:
Other energy management startups that aren’t as closely aligned to Google as Tendril, are, for the most part, excited about the search engine bringing much-needed attention to the space. “It’s great to have Google on the energy-efficiency train,” said Agilewaves CEO Peter Sharer. “Over the past couple of years we’ve been largely swimming upstream.” Greenbox CEO Jonathan Gay expressed the same sentiment, saying he thinks Google will shine a spotlight on the sector and attract interest. Even a spokesperson for meter maker Itron, Sharelynn Moore, said Google “adds enthusiasm and validation” to the industry.
.... will Google be a competitor or a partner? Gay said it’s too early to tell if the product will be competitive to Greenbox, but explains the two as follows: Google is building a platform, while Greenbox, which is focused on the software side of home energy management, is an application that can ride on that platform.
PowerMeter will take data from smart meters and process it into the PowerMeter interface, enabling consumers to see their energy consumption over time. Since smart meters are being rolled out by utilities, the tool will largely rely on utility deals. But Google has also said it is looking at ways to use energy data without smart meters, as well as working with third-party device and application makers.
Hohm is a tool that will enable consumers to see their energy consumption over time and recommend ways to save energy. If Microsoft hasn’t hooked up with your utility yet, you can still enter some basic information into Hohm about location and home, and it will use predictive algorithms to predict your energy consumption. If Microsoft has partnered with your utility, Hohm will integrate your historical energy use, and you will eventually see data from smart meters once they have been rolled out. Hohm will eventually be integrated with applications built by third parties.
