Real-Time Feedback Saves You Money & Reduces Carbon Emissions

Ever wonder how much power you're using? Want to save money on your electric bill? If so, check out the PowerCost Monitor by Blue Line Innovations. This wireless energy monitor tells you how much electricity your home is using from moment-to-moment and in total.

Energy monitors such as this one encourage you to change your lifestyle and reduce your overall carbon footprint, by showing you just how much power your home is using at any given point in time. In fact, it's believed that households that use real-time feedback can reduce electricity use by as much as 6 to 18 percent.

The PowerCost Monitor is a two-part device. A sensor unit attaches to the face of the power utility meter outside your home. Using an infrared eye, it reads the movement of your meter's dial, then transmits information to a receiver/digital display that you keep indoors. It's not compatible with all meters, so be sure to look your's up before placing an order.

Although it will take you a few months to make up for the cost of the unit (~$110), you'll enjoy saving up to 20 percent on your energy bill with the PowerCost Monitor thanks to the sticker shock of watching your energy use in real time.

Windspire Wind Turbine Modeled After Ancient Egyptian Windmill

As wind power is getting a lot of attention here in NC, both in the mountains and off the Outer Banks, I thought it was fitting to cover Windspire wind turbines, which were present at President Obama’s inauguration festivities.

These 30 foot tall and four foot wide wind turbines are different than propeller-based systems; they generate power when the wind blows against vertical airfoils, which is then converted to AC electricity. Each wind turbine produces about 2,000 kilowatt (KW) hours per year in 12 mph average winds, and includes wireless monitoring software so power production can be checked.

Windspire wind turbines cost $9,000 to $12,000, but after rebates they could cost as little as $3,800. There is a 30 percent federal tax credit available, plus local rebates are available in some areas. The average payback is under ten years for the turbines that are designed to last over 20 years. According to Windustry, a wind turbine that's capable of powering an average home costs $35,000 to $50,000.

To see the Windsphere in action, check out this video:



Founded in 2005, Mariah Power launched its Windspire wind turbines in 2008. A Michigan plant began producing the wind turbines in April. The factory used to make automation equipment for all of the major car manufacturers. They were down to five employees when they met with Mariah Power to show how they could make the Windspire with better quality and for a better price. Most of the people who were laid off have been rehired now to work on the Windspire. The plant was featured on ABC's 20/20 on Friday, June 19th.
