Green Options

A couple weeks ago, I wrote about China’s new policy to focus on buying (almost entirely) “China-grown” wind turbines and wind turbine technologies with Chinese patents. That policy wasn’t a big hit internationally and China is back-tracking.

However, is it changing its stance out of international moral pressure or a major financial incentive (recent deal) in the US? And who is to benefit the most from this shift?

European energy giant E.ON “turned on” what is reported to be the largest wind farm in the world this week, in Texas.

The farm contains 627 wind turbines on almost 100,000 acres of land near Roscoe, Texas.

On the endless laundry list of markets that have struggled to muddle through the financial mess known as the global economic crisis, the wind sector seems to be showing signs of a rebound, albeit a small one. A recent article featured in the Financial Times highlighted the “period of calm” that wind producers and investors, alike, are more than relieved to see return in the market.

Prior to the global economic vortex that has sent the sensitive wind market spinning (as well as other renewables markets), wind had been showing strong growth in the first half of 2008. The market for turbine installation was worth $47.5 billion and global wind power capacity was 121 GW - more than twice the 48GW capacity in 2004.

Unfortunately, investors and analysts do not even need the figures from late 2008 and the first half of 2009 to know that the pleasant breeze of financial success had turned into a market maelstrom. In the aftermath, there is reason to hope that recent signs of improvement may lead to more growth.

 

Wind farms in Italy threaten to wipe out the Golden Eagle, farmers` organisation Coldiretti and national environmental organisations declared recently. As concern about climate change and sustainable, eco-friendly alternative energy grows, it‘s surprising that an industry with so much potential – the wind industry – is under fire from environmental groups.

Coming in at second place in the world in energy consumption - second only to the United States - the People’s Republic of China (PRC), the world’s most populated nation, is looking for ways to shift to renewable energy. This desire to increase renewable energy sources and cut greenhouse gases has led the PRC to promote private investments in renewables.

The state of Massachusetts is hunting for unusual places to put wind turbines as it looks to meet an ambitious goal of producing 2,000 megawatts of windpower by 2020.

The Associated Press reports that state officials are encouraging municipal planners to look at using capped landfills as potential wind farm locations. Plans were also just announced for a military reservation on Cape Cod.

The state is hoping to jump start development, because right now, the AP reports, there are only 11 commercial scale turbines in the state. But, ther are dozens of smaller ones installed and nearly 200 other projects in various stages of planning.

A wind farm that was planned for the upstate New York town of Beekmantown and shot down by town officials after a collapse of a turbine at a nearby park, may be back on again.

A new developer has submitted plans to the town, the Plattsburgh Press-Republican reports. The town council voted down a plan submitted by Windhorse Power LLC in March. Among the reasons cited were contentious lawsuits filed by residents, inaction by Windhorse Power and fears of an incident similar to a turbine collapse in neighboring Altona.

Passive structure design of “Wind Energizer” by Leviathan Energy reportedly increases wind turbine efficiency 30% in field tests.

Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. Put simply, the model has been: longer blades = more output per turbine.

But that pattern of incremental improvements may be a thing of the past if Leviathan Energy has anything to say about it. Leviathan Energy has completed initial testing on their Wind Energizer unit and is reporting gains in wind turbine output in the ballpark of 30% — and as much as 150% at lower wind speeds.

The principle theory at work is that by placing passive objects around a wind farm it will change the circulation around a large wind turbine. The advancement is not in the turbine itself, but rather in the area around it, as such, units can be adapted to any wind turbine from any manufacturer.

“This is a disruptive technology,” Leviathan Energy CEO Dr. Daniel Farb told me via telephone from Israel last week. “We are changing the environment of the wind turbine; this is a very different approach.”

Earlier this week Spain’s government approved a map of offshore areas to lease for wind energy development. This move will help Spain to further cement its status as an alternative energy giant.

Spain is already the world’s #3 wind power producer (it trails the U.S. and Germany) and is also the world’s #2 producer of solar power (only behind Germany). Until now, Spain has not used its extensive coastline to develop wind power in a significant way.

In this current gold rush climate for green energy words such as “biggest” and “largest” get thrown around all the time in an effort to grab some headlines.  But this project in Sweden is big no matter how you parse it.

With 1,101 turbines it would be Europe’s biggest wind farm, and as organizers told the Norrbotten county board in the region where the project would be built, possibly the biggest in the world. It would cost 55 billion kronor or roughly $6.9 billion. It would be located in the northern part of Sweden, near Markbygden and occupy 175 square miles.
