Economics, politics, grid constraints, and a fair amount of luck have set in motion an awkward relationship between the natural gas and cleantech industries that could be characterized as “frenemies with benefits.” My colleagues Kerry-Ann Adamson and Mackinnon Lawrence have already shared their views on this complex dynamic, and their outlooks

WindMade, the first global consumer certification for companies that use wind energy, issued its first label to Danish hearing aid manufacturer Widex.
The label is supported by the UN Global Compact and requires participating companies to obtain at least 25% of their electricity from wind power. A wind turbine
On the heels of a decision that imposed a tariff of up to 35 percent on some Chinese solar panel manufacturers, the U.S. Department of Commerce has now ruled that wind turbine towers made in China also benefited from unfair subsidies and has imposed duties ranging from 13.7 to 26 percent on those towers.
This is a question that many of us who follow the clean energy industry may have asked ourselves: which one represents more value for money, wind or solar power? Surely they are both alternative energy types that we should embrace in order to break ourselves from our oil addiction.
Europe has been operating huge wind turbines offshore for more than a decade, while here in the U.S., this cutting edge clean technology seems perennially “five years off.”
The infamous project proposed offshore of Cape Cod, Massachusetts has been under deliberation for more than 10 years. During that time, Denmark,
Puerto Rico currently generates an estimated 70 percent of their electric energy from fossil fuels. Due to the rising cost of fossil fuels and compounded by concerns over climate change, Puerto Rico has realized that they have an obligation to promote healthy economic development and a healthy environment. Puerto Rico’s Constitution supports the
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
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.
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
Recently, Belgium created the Belgium Plan, providing the required steps the European country will need to achieve in an effort to meet their renewable energy and energy efficiency objectives. As the capital of Belgium, the city of Brussels is looking to do its part to streamline the objectives and have Brussels
The American Wind Energy Association has just released its 2011 Annual Market Report, which shows the period registered double-digit growth. The market report highlights how market certainty has been key to the creation of a “positive feedback loop” which allowed for states to generate affordable wind power electricity at record levels.
Advanced Controls for Wind Turbines and Farms Boost Efficiencies, Profitability
written by Walter Wang
Advanced control technologies hold perhaps the greatest potential in the wind energy industry for improvements in individual turbine and entire wind farm efficiency. Using sophisticated, nimble controllers built on innovative principles could be the key to making wind more profitable, even in light of falling government subsidies and research support.
All wind turbines are equipped with a certain power control feature in case the speed of the wind is too high or too low and to have a frequency coherent with the grid. The traditional and the simplest and least expensive method in this respect is a system of natural limitation known as “stall”. The blades are mounted directly on the hub at a fixed angle. When the wind
DeWind Co. (DeWind) is a vertically integrated global wind company headquartered in Germany.
One part of DeWind’s business is wind farm development, and in 2009 the company entered into an agreement with Glenmore Wind Farm, Urban Power, and Prelude by which it agreed to pay
