Duke Energy’s long-term vision is to transform the operation of its electric power grid by creating a reliable and scalable networked infrastructure capable of delivering and receiving information from intelligent devices distributed across its power systems, automating components of the distribution systems and leveraging the linked networks for improved operational effi ciencies and customer satisfaction.
Xcel Energy’s vision of a Smart Grid includes a fully network-connected system that identifi es all aspects of the power grid and communicates its status and the impact of consumption decisions (including economic, environmental and reliability impacts) to automated decision-making systems on that network. This vision leverages the multitude of vertical system solutions currently available and deploys a horizontal integration of these systems into a real-time, automated “neural network” that will manage all of the variables involved in delivering energy to the consumer. We believe this vision of an advanced decision-making system will allow Xcel Energy to more effi ciently deliver energy while providing consumers with valuable information for better decisions on when, where and how to consume energy. The impact will be a greatly improved delivery system that optimizes the impact on the environment, ensures the most effi cient delivery, and maximizes reliability.

How much does it cost to leave your TV on all day? What about turning your air conditioning 1 degree cooler? Which uses more power every month ― your dishwasher or your washing machine? Is your household more or less energy efficient than similar homes in your neighborhood?
Its nearly impossible to make informed choices about electricity. This is a problem but also a huge opportunity for us all to save money and help the environment by reducing our power usage. Studies show that access to your household's personal energy information is likely to save you 5--15% on your monthly bill. Even greater savings are possible if you use this information to see the value of retiring your old refrigerator, installing a new air conditioner or insulating your home. The potential impact of large numbers of people achieving similar efficiencies is even more exciting. For every six households that save 10% on electricity, for instance, we reduce carbon emissions as much as taking one conventional car off the road (see sources and calculation).
At Google we're helping enable a future where access to personal electricity information helps everyone make smarter energy choices. Google PowerMeter shows consumers their electricity consumption in a secure Google gadget. Today we are testing the product with utility partners in the US, India, Germany, and Canada.
We think Google PowerMeter offers more useful and actionable feedback than complicated monthly paper bills that provide little detail on consumption or how to save energy. But Google PowerMeter is just a start; it will take a lot of different groups working together to create what the world really needs: a path to smarter power.
How can you get a personalized energy report for your home?
1 Get your Hohm account: Once you’ve signed up with your Windows Live ID and Postal Code, Hohm will give you useful information about your energy use.
2 Tell us about your home and energy usage: Help us understand how, when and where you’re using energy.
3 View your energy report: Hohm will suggest ways that can help you reduce your energy consumption and your energy bill.
4 Connect with others and share your ideas: Be a part of the Hohm community to share your energy-saving ideas and experiences.
Note: Home Energy Management space; this market is still in the early phases of development as generally speaking you first need to have a smart meter and network in place to generate and transport the end-user data upon which these that these systems rely.
