“Reaching New Heights” uses a combination of time-lapse footage, aerial photography and behind-the-scenes action shots to document the steps involved in building MidAmerican Energy’s first concrete wind turbine tower, located at the company’s Adams wind farm in Adams County, Iowa. At 379 feet from ground to hub, the concrete turbine is more than 100 feet taller than its neighboring turbines constructed with steel towers.
Many of the largest operational onshore wind farms are located in Germany, China and the United States.
By Jordan Blum for Fuel Fix: The Texas electric grid hit a new record for wind power use early Thursday, as the state continues dominating the rest of the nation in wind farm growth. At 12:30 am Thursday, the main Texas grid operator reported that nearly 37 percent of demand was met with wind power. The Electricity Reliability Council of Texas, which manages nearly 90 percent of the state’s electric needs, said it used 12,237.6 megawatts of wind power at the time. That bested a previous record set on Sept. 13 of 11,467 megawatts. A megawatt powers about 500 typical Texas residences during periods of normal demand. The new record came the same day as the American Wind Energy Association reported Texas accounted for nearly half of the nation’s wind power growth in the third quarter of the year. Texas added 771 megawatts of wind generation in the third quarter and, nationwide, about 1,600 megawatts were put online. Texas now has about 16,400 megawatts of wind power, according to the AWEA, which is about 10,000 megawatts more than the second and third windiest states, California and Iowa. Cont'd...
6th annual conference on Wind Turbine Blade Manufacture 2015, which takes place from 30th November to 2nd December 2015 at the Maritim Hotel in Dusseldorf, Germany.
Dominic Bates for The Guardian: A new bladeless wind turbine that promises to be more efficient, less visually intrusive, and safer for birdlife than conventional turbines has been welcomed by two of the UK wind energy industry’s most vocal critics. The RSPB and the Campaign to Protect Rural England (CPRE), which have both expressed concerns over the impacts of industrial-scale windfarms on the landscape and wildlife, said the new turbine was encouraging news for birds and had the potential to open up more urban environments to the sector. The streamlined design contains no contacting moving parts, making it virtually noiseless and less prone to vibration. Vortex Bladeless, the turbine’s Spanish developers, hopes these advantages could finally help usher in a viable consumer wind power market. “Wind turbines now are too noisy for people’s backyard,” says David Suriol, who co-founded the company with Raul Martin and the turbine’s inventor, David Yáñez. “We want to bring wind power generation to people’s houses like solar power.”

Oklahoma's pro-business climate and excellent wind resource have helped to attract wind developers from across the country and the globe.
The U.S. now has an installed wind capacity of 61,327 MW. There are over 13,000 MW currently under construction, an industry record.
Inland sites can offer sufficient wind yield for wind-farm operation. Initial results obtained from a TÜV SÜD test wind mast show that wind yield depends on the specific location.
The benefits of a centralized database and platform for managing data extend beyond the scope of one software product.
Technologies to harness high-altitude winds have been around for several decades now but are still in the planning or prototype stage. When these systems are placed into use, the cost of high-altitude wind energy will range from two to four cents per kilowatt hour.
One of the many challenges of operating a wind farm is meeting ongoing payments. The right technology can help wind companies meet this formidable challenge. That, in turn, helps to advance further development of wind power.
The debate of the PTC just took too long and put the players to uncertainty. Installations were pushed in 2012 to record level of almost 13 GW. This year will be a big dip to estimated 4 GW or so and midterm the installations should level on 7 GW level.
Over the past few years we've seen a real interest from schools, commercial sites, and homeowners. Local and federal governments are also seeing the benefit in on-site energy generation.
The two countries where we have seen the most substantial investment and growth is China and India, where they see opportunities to export technologies worldwide and invest in global solutions. This is something that Europe has practiced over the past few years.

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
