The small wind market is doing well these days with lots of new companies popping up all the time. Since 2007, Urban Green Energy, one of these newish companies, has been expanding and growing — their vertical axis wind turbine (VAWT) has been installed in 48 countries. One of their most recent installations was broadcast to the world last month on ABC’s Extreme Makeover: Home Edition (pictured).

Depending on where you are on the Pyramid of Water Conservation, you may still have turf grass or an irrigation system, or both. And these things guzzle water like crazy through Spring and Summer. If you’re thinking about using less water and saving more money at the same time, perhaps UgMO Technologies — short for underground monitoring — could help out with their water-saving UgMO ProHome system.
Pythagoras Solar makes a revolutionary solar-powered window – literally an insulated window with integrated photovoltaics – that has the ability to turn buildings into massive power producers. The company has been testing a pilot project on the south-facing windows of the 56th floor of Willis Tower, formerly known as Sears Tower. If the pilot goes well, Willis Tower could end up with a surface area of up to two megawatts of solar.
The U.S. market for small wind turbines — those rated 100 kilowatts or less — grew 15% in 2009 with the installation of about 10,000 new units, according to the AWEA Small Wind Turbine Global Market Study in 2010. In the same report, AWEA found that the largest manufacturer of these turbines in terms of kilowatts sold is Arizona-based Southwest Windpower. I had the opportunity to email with the company’s marketing director, Miriam Robbins, and she was kind enough to share what’s new with Southwest Windpower.
Sunnovations, a Virginia-based start-up, is seeing more and more interest in its unique solar thermal technology and just closed a Series A round of financing led by Two Seven Ventures. That technology is explained in the attached images, and it may just make solar water heating a no-brainer for every home in the country. The system is relatively affordable, easy to install, and simple to maintain, according to the company.
Today Lighting Science Group unveiled a new 60-watt replacement LED bulb that “meets or exceeds all of the criteria for the L Prize,” according to CTO Fred Maxik.
