Global Wind Power Projections for 2010. Both Onshore and Offshore Wind Sectors To Continue Upward Trends

2010 Jan 4

As well, the growth in the offshore sector, which has lagged the onshore sector, will continue to develop and grow as more governments and power generation companies locate areas where the wind energy warrants wind farm development.

Wind Power a Viable Energy Source

In 2010, the global acceptance of wind power as a viable alternative energy source is closely related to the capability of the international community and governments of all countries to negotiate and agree upon legally binding terms on limiting greenhouse gasses.
While Copenhagen 15 did not result in any binding agreements on limiting greenhouse gasses, wind power was represented by a large wind turbine erected on-site, a massive rotor blade, and photographs of onshore and offshore farms.

European Wind Power

In Europe, which has a much longer experience with the capability of wind power to generate electrical energy, than North America, wind energy has become a driving force, and the European Wind Energy Association (EWEA), the voice of the European wind industry, reports that it now has over 600 members from almost 60 countries, with a 90 percent share of the world wind power market. Members include manufacturers, plus component suppliers, research institutes, wind and renewables associations, developers, electricity providers, finance and insurance companies and consultants
European wind power will continue to grow as the older and antiquated onshore grid systems are enhanced and a dedicated offshore grid is established.

US Must Transition to Clean Power by 2012 or Miss the Chance

2010 Jan 26

If the US was smart, we would be funding a massive switch to renewable energy now, while we still can. By 2012 we could be out of luck. China is sitting on the only currently mined sources of many of the rare earth minerals needed to build electric cars, solar panels and wind turbines. Reasonably enough, having developed the resources, China wants to keep them for its own needs, that is has planned for.
But we are not smart. Even before the Supreme Court ruling this week, we already allowed fossil interests to dictate our energy policy by allowing the purchase of both policy makers and the formerly public airwaves to impede smart energy policy. In no other democracy is such corruption allowed.
The result is that we will be out of the ability to protect ourselves from peak oil from 2012 to at least 2020 (the earliest that new rare earth mines outside China might begin to come online). If we don’t pass effective climate legislation this year, we will miss that crucial transition window.
Now that other nations are beginning to move into renewable energy development, the world will need 200,000 tons of rare earth elements by 2014. In just a decade world needs went from 40,000 tons to 120,000 tons, but there is not enough to go around. Faced with shortages, China plans to stop exporting completely by 2012.

Adobe Installs Windspire Turbines in Downtown San Jose - VIDEO -

2010 Jan 19

Adobe Systems is yet another company that has jumped on the alternative power energy bandwagon. Located in the heart of Silicon Valley, Adobe Systems has installed 20 Windspire vertical axis turbines atop the parking garage of its LEED certified office complex.
While the feasibility of placing wind turbines in urban areas was once problematic, new integrated systems have made it possible for wind energy to be used in cities and residential areas.
The Windspires, installed last month, are the first wind turbines to be installed on a downtown San Jose building. The sleek and near-silent turbines, manufactured by Mariah Power, each stand about 30 feet tall, measure four feet in diameter and weigh about 650 pounds. And the Windspires, made in the USA, are made from 80 percent recycled materials.
Although Adobe doesn’t have enough room for a significant roof-top solar system, there is plenty of wind. The software company’s three office towers, which stand 16, 17 and 18 stories high, help funnel the wind across the roof of the parking garage, which also serves as an open-air patio, basketball and bocce courtyard for employees.
And because the propeller-free turbines turn more slowly making them more visible than traditional turbines, the manufacturer says birds and bats are less likely to be harmed. In fact, there have been no reports of bird collisions thus far. And because peregrine falcons and other birds are frequent visitors to the headquarters, installing a bird-friendly system was important.
According to the company website, the 1.2 kW Windspire will produce about 2,000 kilowatt hours annually, in 12 mph average winds. It is anticipated the 20 turbines will produce less than 2 percent of the power used at the headquarters. According to Inhabitat, the San Jose-based company will eventually use the electricity generated from the turbines to power an EV charging station in the garage and the San Jose Semaphore.

The wind energy of the future

2008 Dec 2

Thousands of massive wind turbines might not be the ultimate solution after all. Bigger is not necessarily better when it comes to wind energy.

Doug Selsam, CEO of Superturbine, Inc. and wind turbine inventor, certainly doesn’t think so. He knows “small is beautiful”.

Cheaper, lighter turbines can operate on an industrial scale. Doug gets 400 watts per pound out of his small rotors, where as the giant megawatt rotors get 30 watts per pound, that’s a better than 10 to 1 ratio of improved performance.

What’s different about Selsam’s design is its simplicity; no gears or other complex parts, just one spinning drive shaft!

A small module, such as an assembly of 8 propellers in line can produce up to 2 kilowatts. He can make this assembly longer and get more power, he can multiply the assemblies, the sky is the limit…One could imagine thousands of these drive shafts side by side and it would be enough power to run a small city.

Mass Megawatts Could Bring More Efficient Wind Power to Ski Resorts

2009 Dec 27

Mass Megawatts Wind Power, Inc., is testing new wind turbine equipment that could help boost the efficiency of the company’s Multi-Axis Turbosystem wind power generators. The tests are under way at a wind power installation in Hunter, New York.

If successful, the technology could start appearing soon at ski resorts in the Pocono Mountains of Pennsylvania. Last spring the principal owner of one major ski facility in the region, Camelback Mountain Resort, took an equity position in a licensed manufacturer of the Multi-Axis Turbosystem. It appears to be a first step toward introducing sustainable wind power to ski resorts on an industry-wide scale.

SoWiTec, Enel to Develop 1,000MW of Wind Power in Mexico

2009 Dec 4

A Mexican subsidiary of Germany's SoWiTec international GmbH has signed a development agreement with Enel Latin America LLC to develop several wind power projects in Mexico with a total capacity of up to 1,000 megawatts (MW).

Enel Latin America LLC is a subsidiary of Enel Green Power-- a business unit of Enel (ENEL.MI).

Through this agreement, Enel Green Power (www.enelgreenpower.com) will have exclusive access to wind power projects being developed by Sowitec de México Energías Renovables, as well as the right to acquire these projects once they are fully authorized. The projects are located in the states of Sonora, Coahuila, Aguascalientes, Tamaulipas and Veracruz with a preliminary capacity for each project ranking between 100 to 200 MW.

SoWiTec has been present in Mexico since 2007 and is developing a pipeline of more than 5,000 MW of wind projects all over the country.

SoWiTec and Enel have already signed similar agreements for 1,000 MW in Brazil and 850 MW in Chile. With these three agreements the total project volume to be built within the next few years amounts to some 1,500 wind turbines.
