The article states, "Asia is slated to witness the fastest growth in installed wind capacity, to reach 25.5 GW by 2013." It would be depressing if this were true. Already today, China has exceeded the 25.5GW installed wind capacity, and China is only part of Asia. For the above statement to be true, Asia would have to start taking down windmills rather than adding new ones.

I would assume the author and the gentleman from Seimens mean 25.5 GW per year by 2013. That's an incredible number, but it certainly seems doable.

Renewable are a proven means to lessen our societies need on traditional fuels. Although there is much excitement over the new advances in energy creation, the reality of it is we are not going to get away from fossil fuels anytime soon. Renewables make only a fraction of our energy mix in the United States. Even if we continue to invest at the same rate we are, we will be lucky to install 20% of our capacity in renewable sources. Whether we like it or not, oil and gas are here to stay for awhile. What is more important, however, is how we use these resources. For so long we have used fossil fuels literally as "free energy". This is not the case anymore. We must strive to break this habit by promoting more fuel standards and efficiency, as well as aggressively investing in renewables.

I am a member of the Spirit of Ireland iniative, www.spiritofireland.org
The basic idea of our project is to effectively marry renewables with seawater pumped storage, in order to create a dispatchable on demand natural energy power staion.

Ireland is blessed with enormous wind and ocean energy resource's and is also fortunate in having u shaped glacial valleys close to the atlantic coast. By using the ocean as the lower reservoir and building a dam across the mouth of one of these valleys we will create an extremely cost efficient pumped hydro storage facility with a capacity of 100GW/hrs.

By using the output of large scale windfarms and later wave farms to pump seawater into our valley/HSR, we can create conventionally despatchable electricity with no intermittantcy.

A natural energy power station.

We are now into the permitting process for our first project, with a rated output of 1GW.

Take away the mandates and subsidies and see what happens to this erratic power source.

The article title, "Is current wind growth sustainable" is troublesome on two counts. First, it should be obvious to anyone with cursory knowledge of our energy situation that we've harnessed only a small portion of the potential wind resource. Second, the word "sustainable" in its contextual usage has to do with whether an energy source sustains the health of the planet. A better formulation would have been, "Will the growth rate of wind energy be maintained?" In this translation, it still strikes me as a naive question and is a magnet for platitudinous responses.

You raise a valid point, Joel, but the point of this type of article is to open the debate rather than to limit the discourse to those with an obvious stake in the success of the industry.

Though evidently those with an intimate knowledge of the business are more likely to hold an opinion, we nonetheless invite and welcome any response to the same question - from those with a less favourable view too.

I also work for a company in the process of licensing pumped hydro storage but because of the environmental concerns connected with the aquatic resource we have designed what we termed CLPS or closed loop pumped storage. We build two reservoirs and replenish for evaporation when needed. Because the wind here in the western US blows mostly at night this is the best storage possible. It should be welcomed with open arms by the wind folks but they remain in denial for the most part. We should be filing for FERC licensing later this year. We have sited 10 such projects located near major transmission sources in relatively environmentally benign locations.

In answer to the article's question yes if massive bulk storage is available. See symbioticsenergy.com and follow the links to our storage projects.

I am still not sure about the energy used by the backup power! A director of Electrabel once stated on television, that in a special year all the energy produced by their windturbines was compensated by the fuel for the backup powerstations (mean load of the turbines in that year 14%).

Texas has good winds and 3 times the name plate wind of any state. In 2009, ERCOT reports Texas wind farms had an 8.7% capacity factor and produced 1%(repeat one percent) of Texas 72,000 MW summer wind requirement. There is no effective massive bulk storage for wind's excess. That's why it is a supplement, not a substitute, for base load power.

I don't see why windpower's current growth would not be sustainable from its current still low percentage of electricity markets. Simply keep mandating it over all other forms of energy and back it up with natural gas. The question should be is this economical and no government is doing prudent cost-benefit to find out for the public good.

It is sustainable Mike, with the current mandates and 2.1 cent/kwh hour subsidy which is nearing $1.5 billion/yr. If you gave that to nuclear it would be at $17 billion, indicating the relative amount of power generate by the two sources. If you halted it for wind, the wind business would be as quiet as those turbines on hot summer days when there isn't a "breath of air" and grid demand is at its peak.

OK Rolf. But let us deregulate the power industry fairly and let power sources be decided by free markets or at least cost-benefit analysis but certainly not politics. I also oppose Obama giving $55 billion in loan guarantees to nuclear. (BTW, I believe I live down the road from you in Crosslake).

Mike, you are just up the road, as we are on Bay Lake a little south of Ruttgers.
Those loan guarantees won't cost the taxpayer anything as nuclear plants are profitable and the loans will be repaid. Minnesota's 3 reactors are gold mines for Excel with total operating costs around 2 cents/kwh.
You may read my energy articles in the Brainerd Dispatch, Duluth News Trib, Echo, etc.

Wind needs to read the curtailment report, because most wind blows at night it can't be used; dreaming about the day when electric cars will suck up that extra power won't keep all proposed wind sustainable until that point in time. More so the argument concerning storage isn't about its net loss of 14% its about its ability to smooth out the grid thus removing the variability factor of both solar and wind plus its ability to respond to minute by minute demands at the load centers.

The energy balance for wind farms is very good with a return of about 15 times the manufacturing and construction energy input. The grid will adapt and there is great scope for innovation in generation, transmission and demand technologies and commerical arrangements, even moreso when you consider all the renewable technologies and not just wind (maybe like the changes the internet has brought in the last 10 or 15 years).

Wind is not a replacment for baseload but with a mix of technologies and innovation much is possible in reducing the need for fossil fuels.

I don't think the comparsion between the dotcom bubble and the wind industry is very relevant. Market forces have no impact on where or when the wind blows and demand for electricity is still strong.

I think the future for wind is good until we see significant inroads by renewables into the electricity, transport and heat markets, which will take a good few years to achieve. The geographic versility of where wind farms can be developed and its modular nature are still key industry strenghts.

To the gentleman who commented on the nameplate capacity for Texas wind farms. Below is a quote from a press release from ERCOT issued May 29, 2009:
ERCOT continues to lead the nation with the most installed wind generation capacity at 8,135 MW, according to the summer assessment. For summer peak capacity, ERCOT counts 8.7 percent of wind nameplate capacity as dependable capacity at peak in accordance with ERCOT's stakeholder-adopted methodology.
The statement released by ERCOT comments ONLY on what it views as reliable capacity during summer peak demand, the least windy time of the year in Texas. Let's not imply that all wind farms in Texas produce at 8.7%throughout the year. There's already enough misinformation out there.

The NREL study suggesting 20% wind power for the US by 2030 predicts that capacity additions will peak at 16 GW/year and that that value is also all that will be needed to sustain the 20% value after it is reached. Last year the US installed 10 GW, so if the study is to be believed we will either experience a marked slowdown in the rate of growth of capacity additions in the near future, or we will somehow address the intermittency problems that will arise beyond the 20% of total generation level or we will experience a bubble in the industry.

Costs or lack of them - what does this mean for environmental protection? If a man depends on the life according to nature, it has developed various new technologies for electricity generation. At the same time must come to terms with the various consequences of this type that accompany an investment or project. But new methods of electricity generation are there to protect ourselves and our planet, right? So let us build and develop as much renewable energy sources.

Right now, infrastructure providers are producing wind towers that can stand at 120 meters, with generators that are 75% smaller than the present standard, producing the same amount of power at 99% mechanical to electrical efficiency. Just imagine what we'll be capable of in another 20 years!

Try walking around a wind park (No, not driving a fossil fuel or electric vehicle) and you will realize at HUMAN scale that this technology can't work without an outside concentrated energy source like fossil fuels. Look at Cuba (Yes Cuba) which is the only country defined as being sustainable on the planet and you will see that they can't implement wind or solar without outside help (fossil fuels) and what a perfect spot for this technology.
