Google PowerMeter now offers "personalized energy savings recommendations" to help you save more energy and show off your savings. "You can find it under "Take action" in your PowerMeter page. Over time, the feature will provide even more useful tips. As your energy consumption behavior changes, you'll receive new recommendations to help you save even more. In addition to receiving customized energy saving recommendations, you'll earn a special badge when you complete a recommendation," informs Google.
Also you can now easily see how much energy you're using with a new display feature on PowerMeter chart. Now, when you move your cursor over the chart, you'll see a pop-up that shows the amount of power used at that moment in time.
