Sauer Energy, one of the leading companies in the small wind segment, is getting its product closer to the consumer after striking 25 distribution deals for its WindCharger wind turbine, a vertical axis unit to generate wind power on a small scale.

WindCharger only requires a wind speed of five miles (more…)

The U.S.’s continued reliance on coal and natural gas to generate electricity makes efficient gasoline-powered vehicles a lower-carbon alternative to electric vehicles in most states, according to a new report by Climate Central.

In an analysis of life-cycle emissions from vehicles, (more…)

Exhilaration swept through the energy efficiency industry as city after city, state after state and nation after nation set aggressive energy saving goals over the last several years. But with target dates nearing in certain jurisdictions, a more sober attitude now permeates. Some governments are asking: Are we reaching too high? (more…)

Imagine this. You live in historic home built in 1916. At the end of your flagstaff walkway, pale grey banisters lead you up weathered stairs onto a wrap around porch. The front window is grand and welcomes early morning sunshine in as you drink your robust Columbian blend. However, your morning coffee isn’t agreeing with you. It’s not that the table cream (more…)

Solar3D, a company that develops a three-dimensional solar cell technology to increase conversion efficiency, appeared on News and Fox Business Network last weekend. The article featured an interview with company’s CEO Jim Nelson.

Solar 3D employs the same principle of fiber optic (more…)

In a sharply worded analysis that will cause fear and trembling in the U.S. cleantech industry, a group of three research and policy organizations have produced a report saying that a cleantech collapse is imminent in this country unless subsidies, incentives, and federal policies are extended and reformed. Entitled “Beyond Boom & Bust,” the lengthy report from the Brookings (more…)

Two years ago, an explosion on BP’s Deepwater Horizon drilling platform killed 11 workers and marked the beginning of a prolonged environmental disaster now acknowledged as the worst in American history. Before the Macondo well was finally capped, more than two hundred million gallons of crude oil had gushed into the Gulf of Mexico, killing untold (more…)

U.S. and UK officials have announced plans to work together in developing floating wind turbine technology, an innovation that could open new areas of the world’s oceans to wind energy generation.

In a collaboration announced before a meeting of global energy leaders in London, U.S. Energy (more…)

In previous posts (here and here), I discussed the IP litigation in China between American Superconductor (AMSC) and Chinese wind energy system maker Sinovel.

The of heart of the dispute is AMSC’s allegations that Sinovel misappropriated its proprietary software code for controlling wind turbines and power converters. (more…)

Wind density is an issue for the wind power industry. The windier the site, the higher the energy output will be. But a new product, launched at the EWEA 2012 in Copenhagen, promises to achieve maximum returns from low-wind sites. The makers hope it will become a benchmark in the industry thanks to its low power (more…)
