Rooftop Wind Turbine Idea

There’s a lot of reasons why most homes in America do not have their own wind turbines — high costs, permitting issues, and just plain aesthetics. But there’s a wave of entrepreneurs trying to change that, including James Post, who has developed the SmartWind RidgeBlaster and submitted the concept to GE’s Ecomagination challenge. Watch the video (complete with music that would make the Techno Viking proud) below for a comprehensive description of the idea. It’s a wind turbine that stretches horizontally across the ridge of a gable roof, and has a diameter of 22 inches. The wind is meant to sweep up the roof through the turbines and the design is supposed to be able to utilize wind at any angle. According to GE’s materials on the concept, the customer would pay around $4,000 for a 1.8 kW, plus the cost of a 3 kW grid-tied inverter.

Report says Geothermal Energy to double by 2020

The world will see a significant increase in the use of geothermal as an energy source between now and 2020. That's according to a report released this week by Pike Research. The research analyst constructed several scenarios based on an estimated 10.7 gigawatts of geothermal capacity in existence throughout the world in 2010. That 10.7 gigawatts equates to about 67 terawatt-hours (TWh) of electricity, with the U.S., which currently possesses 3.1 gigawatts of installed geothermal systems, as the world's leading user. In fact, 88 percent of the world's geothermal energy systems currently in operation are used in only eight countries, according to the report. Peter Asmus, the senior analyst on the report, emphasized that geothermal is currently one of the world's least-tapped opportunities for alternative energy. In the report's high-growth forecast, geothermal capacity increases 134 percent to 25.1 gigawatts. In the report's most conservative forecast, Pike estimated that world geothermal capacity will grow to 14.3 gigawatts by 2020.

S-5!® PVKIT™ 2.0 Solar Rooftop Solutions

S-5!® PVKIT™ 2.0 Solar Rooftop Solutions

The concept of combining PV arrays with standing seam metal roofing is growing-for good reasons. Metal roofs have a life expectancy of more than 40 years. Shouldn't the mounting system last as long? With S-5! zero-penetration attachment technology and PVKIT 2.0, the solarized metal roof is the most sustainable system available -and without compromising roof warranties! PVKIT 2.0 is the also the best solution for attaching PV modules directly to any exposed fastener metal roof.
