DOE data show states with most wind energy have largest electric rate decline

Newly released Department of Energy (DOE) data show that consumers in the states that use the most wind energy have fared far better than consumers in states that use less wind energy.

The 11 states that produce more than seven percent of their electricity from wind energy have seen their electricity prices fall by 0.37% over the last fice years, while all other states have seen their electricity prices increase by 7.79% over that time period.

The following charts summarize the change in power prices for consumers in Texas, Wyoming, Oregon, Oklahoma, Idaho, Colorado, Kansas, Minnesota, North Dakota, South Dakota, and Iowa compared to all other states. Between the end of 2008 and the end of 2013, these eleven states more than doubled their operating wind power, increasing their wind capacity by 116%.

Onshore Wind Is The Cheapest Electricity Generation Option In Europe

The falling cost of renewables is not news to those who have paid attention to analysis from green-focused think tanks, or groups like Bloomberg New Energy Finance. But it is when a major European utility, with equal exposure to fossil fuels, wind, and hydro, says that onshore wind is the cheapest of any new utility-scale technology.

That is the assessment of Portugal’s EDP, which has around 24 GW of generation, of which around 8.7 GW is in onshore wind.

In a recent presentation to analysts, EDP’s head of renewables Joao Manso Neto presented this slide below, which shows that the levellised cost of electricity of onshore win in Europe is 20 per cent cheaper than gas and one third cheaper than coal. (The figure assumes 25 per cent wind capacity factor).

European Wind Power: Denmark, Portugal, & Spain Leading the World

The Earth Policy Institute always produces great content, so I’m happy to share another article from that team via this sustainablog repost. Beforehand, however, I’ll just point you in the direction of a bit more (context from previous CleanTechnica articles).

We’ve got articles with more details on some of the points quickly noted below, such as Denmark rising above 30% electric from wind power, wind generation getting to #1 in Spain, as well as Denmark, Spain, and Portugal’s wind power leadership in relative terms such as wind power per capita and wind power per GDP.

And for a ton of wind fun, check out these wind energy facts and charts.

2 Big Hints That US Offshore Wind Power Will Dominate

So far, the story of the US renewable energy transformation has skipped a key chapter, which is the exploitation of our massive offshore wind power potential. In the offshore wind category, the US has been lagging far behind other nations. However, the spotlight is starting to swing out to embrace this wind power option, and we picked up a couple of tantalizing hints that US wind power, both onshore and offshore, is set to explode in the coming years.

One big hint was dropped on Saturday by President Obama himself in his weekly radio address Saturday morning. The speech laid the groundwork for Monday’s highly anticipated announcement of new carbon pollution rules for power plants, so you can bet that every word was weighed carefully.

In that context, consider that when Obama listed the progress that the US has made in clean tech under his Administration, he cited a laundry list of accomplishments leading off with wind power:

Thanks in part to the investments we made in the Recovery Act, the electricity America generates from wind has tripled. And from the sun, it’s increased more than tenfold. In fact, every four minutes, another American home or business goes solar – and every panel is pounded into place by a worker whose job cannot be shipped overseas.

Now consider that the President touted US wind power even though we don’t have a commercial offshore wind power farm in operation yet, despite our massive offshore wind power resources.

For the record, Rhode Island offshore wind power is on track to be first out of the box, probably followed by Massachusetts, despite the usual Koch brothers shenanigans.

And here is another fine example. With all that has been happening with wind power over the last ten years we find it necessary to jam the entire topic in a "THE" thread?

For shame! It's an ENERGY topic that is directly related to Hydrocarbon Depletion!

Wake Up!
Stop filling dumpsters, as much as you possibly can, and everything will get better.

Just think it through.
It's not hard to do.

To sell offshore wind as dominating is nonsense, you only have to read relevant papers:

Onshore wind has much more potential (one order of magnitude) and is much cheaper (2-3 times). Offshore is a nice addition but no substitute. The backbone of RE infrastructure in most developed countries will be onshore wind.

U - Yes... very strange story. I've home over Texas wind before so I'll skip thus time. The first offshore wind pilot project went up offshore Texas a few years ago. We offered the first offshore wind leases in the nearshore state waters. Unlike all the other states Texas has sole authority over this area.

Big plans for wind offshore Galvestn and S Texas. But I'm also a bit skeptical they'll be built for the economic reasons you mentioned. We have a huge wind for right along the coast where one of the big offshore projects is planned. No local resistance and the land is mostly scrub with few municipalities. Here and on our vast and barren western planes it's much cheaper. And now the state has greatly expanded the distribution system which had actually been a big factor in developing more onshore wind.

I've worked operations in the GOM offshore region for almost 4 decades. It is a very expensive theater to function in and that's even with our huge and competitive offshore support system.

Yes U is correct but offshore wind does have environmental "value".

Onshore wind has the advantage of being one of the most affordable renewable energy sources. Generating electricity from onshore wind turbines typically costs around 7–9p per kWh, which is around half the cost of offshore wind and a quarter of the costs of solar photovoltaic panels.


Onshore wind has been criticised for its visual impact. Although other power infrastructure, like fossil fuel and nuclear power stations, can also modify landscapes and habitats, onshore wind turbines are typically more spread out than other large-scale energy infrastructure projects and so can affect a larger area. Another criticism is that species such as birds and bats may also be affected by wind turbines – though bird fatalities due to turbine collisions are relatively low compared to other fatality causes, such as traffic and domestic cats. Impacts on wildlife can be minimised by careful site selection and by avoiding areas of high conservation or habitat value. A third potential issue is that turbines can contribute to noise pollution, but government studies find noise levels are comparatively low and should not significantly impact on nearby residents. New guidance is being drafted to inform future planning policy on noise issues.

Environmental Impact Assessments review these kinds of potential impacts on a case-by-case basis and seek to protect unsuitable areas, such as those of high conservation or heritage value. In some cases, undesirable local impacts may make more expensive renewable technologies, such as offshore wind or solar, more attractive. The extra cost of offshore wind can be seen as the premium society is willing to pay in order to avoid the local environmental cost of onshore turbines.

Cost of wind energy is lower thanks to thousands of U.S. companies, now ready to do more to meet EPA rule affordably

U.S. wind industry developers, manufacturers and other key players have worked hard for years to make wind energy cheaper. As a result, today they express confidence they can deliver a reliable, affordable product – wind energy – to states and consumers to meet EPA’s proposed rule limiting carbon emissions from existing power plants.

Wind energy is cheaper by 42 percent in four years, thanks partly to 560 factories making wind energy components across 44 states. Utilities and other power providers have increasingly been signing contracts for wind energy, because they can get long-term, fixed-price deals that help hedge their portfolio against the price volatility of fuel-based sources. The thousands of U.S. companies that help manufacture, develop, build, and service wind turbines are capable of leveraging up to $25 billion in private investment in a single year.

Below is a collection of responses from U.S. wind industry companies to the announcement of EPA’s proposed rule:

Graeme,

the avarage size of a new US onshore wind turbine is still much smaller than that of an European turbine, this indicates for me that there is not a lack of good sites in the USA. If you want to reduce the enviromental impact for really cheap money I would simply increase the avarage size.

Offshore was in 2000-2005 considered essential for Germany due to its high FLH (4500) and the small size of onshore turbines, however, with the developements in 2005-2010 in respect to layout of onshore turbines this physical argument has died, it is now politics:

Offshore wind in Germany gives additional investment opportunities for large utilities which have no chance here in Germany to get an larger onshore market share, most interesting sites are used by the owners or local energy cooperatives. :-)

In North America with much better onshore wind resources and much much lower population density compared to Germany I simply do not see any longer a good argument for offshore wind.

I wonder if offshore wind installations that happen to be areas of strong tidal currents could have one or two tidal turbines tethered to each wind tower foundation. The tidal power would be more predictable then wind and use the same power distribution cables increasing the energy produced per mile of distribution system.

U - That's why I wonder if the Texas offshore wind projects are just opportunistic efforts to suck in investor $'s. For fun you might Google the land areas along the S Texas coast and the plains in western Texas. It certainly ain't Germany. LOL. And the reality is that most of those lands are used to run cattle. And the cattle aren't bothered by wind turbines and thus agricultural productivity isn't reduced. And the visuals for the landowners out there? Wind turbines vs. scrub grass and cow butts? Not much of a sacrifice. LOL

As I pointed out before I'm very familiar with offshore ops cost. Send a tech 80 miles to work on a turbine in S Texas: transport cost...$300 max. Send him offshore 80 miles: $5,000 to $10,000. And building a wind tower on dry land vs. one just off the coast? I wouldn't waste time running the numbers. LOL. Here's a link showing what the land and owe look like. The picture could be just 10 miles from the coast. I won't bother to post a picture of water looks like 10 miles off the coast.

http://www.bloomberg.com/news/2013-10-1 ... -fade.html

And don't pay attention about the BS from the King Ranch folks that complain about both the sight of the turbines and the danger to birds. They aren't Ranch folks living off the land. They are a management company running a multibillion $ operation for the Kleberg that is one of the biggest oil/NG properties in Texas. And birds? Literally millions of birds have been killed on the Ranch by hunters. And most were those cute little doves that migrate through the area every year.

The Klebergs...a taste: Earlier this year, the San Antonio Court of Appeals issued an opinion in a case contesting the will of Belton Kleberg (B.K.) Johnson, greatgrandson of the founder of the King Ranch. Johnson died in 2001 at the age of 71. In the 1950's, Johnson was passed over to head the management of the 825,000-acre King Ranch lands, and he sold his interest in the Ranch in 1976, but kept his royalty interests. Johnson's life and the will contest opinion give a rare glimpse into the world of the rich and powerful in South Texas.

Great idea! Maybe you could attach wave and solar power modules as well.

I found some news about offshore wind in China (conclusions applicable to USA), and a wind fact sheet.

UK Skills Can Speed 5,000 MW China Offshore Wind Plan For 2015

In a tripartite report released Friday, the Carbon Trust has suggested China accelerate its progress with offshore wind energy by taking cues from the UK’s extensive research, funding, and deployment expertise.

Like other nations, the colossus of southeast Asia has major concerns about continuing to rely on coal for energy. Coal currently supplies about 70% of China’s power, and China has relatively recently overtaken the US as the world’s #1 greenhouse gas polluter. The Chinese government has established ambitious targets of 5,000 megawatts (5 gigawatts) of offshore wind power installed by 2015 and 30,000 megawatts by 2030. Supplying large amounts of wind energy close to the country’s huge east coastal cities would help meet demand in a renewable and geographically sensible way.

To that end, the Chinese Wind Energy Association and CECEP Wind-Power Corporation teamed with the British Embassy in Beijing to investigate ways a China offshore wind plan could scale up its capabilities quickly. Over 20 Chinese companies collaborated with the Carbon Trust to assemble the reports (PDFs available below):

Offshore Wind in China—Sharing the UK’s policy experience


Mapping existing technology solutions to barriers identified in China’s Offshore Wind industry


Detailed appraisal of the offshore wind industry in China

Presently, China is developing about 1,000 megawatts of nearshore projects, but technical and commercial barriers are hindering these efforts toward a China offshore wind plan.

The Carbon Trust identified some of the technical issues as corrosion and heat with Chinese-manufactured turbines offshore and uncertain foundation stability for traditional concrete monopile towers in the soft, silty soils of China’s east coast.

Wind Power Fact Sheet

Wind power capacity is an indicator of building a sustainable economy because wind is poised to become the foundation of the new energy economy.

With total capacity exceeding 318,000 megawatts, wind farms generate carbon-free electricity in more than 85 countries. Twenty-four countries have at least 1,000 megawatts.

The wind power capacity installed worldwide would be enough to meet the residential electricity needs of the European Union's 506 million people.

Wind is abundant, carbon-free and nondepletable. It uses no water, no fuel, and little land.

Although a wind farm can cover many square miles, turbines occupy only 1 percent of that area, leaving space for growing crops or grazing livestock.

Unlike coal, gas, and nuclear power plants, wind farms do not require water for cooling.

In China, wind-generated electricity surpassed generation from nuclear power plants for the first time in 2012. Wind's advantage over nuclear increased dramatically in 2013.

In the United States, wind accounted for at least 12 percent of the electricity generated in nine states in 2013, including Iowa (27 percent) and South Dakota (26 percent).

Texas, long the leading oil-producing state, is now the U.S. wind power leader.

That's what I'm talking about but I think they have it upside down. Much easier to lower it from an anchored barge to the optimum depth and be able to pull it up for service. In the case of a wind tower foundation you would mount two on a ring surrounding the foundation column 180 degrees apart set so it would weathervane with the changing tide and utilize both incoming and outgoing tides. You might even have the hoist mechanism on the mounting ring controlled during operation to seek a depth that has the right velocity of tide flow to yield the desired power output. A governor if you will that is more versatile then the wind generator on top of the tower which is take it or leave it.

Newbie - Exactly. I just wanted to give our cohort a starting point. If I recall correctly much of the early enthusiasm for ocean sourced energy generating systems has fallen off. A west coast wave energy generating project was canned not long ago. Sorts like rust never sleeping: the ocean is relentless in attacking infrastructure 24/7. Turns out Mother Earth doesn't care what we model...she has her own methods. LOL.

Actually, I just remembered another benefit of offshore wind - reduce the intensity of hurricanes. Google it. This would be quite an important benefit in the southern and eastern US unlike in Europe. Here is a recent development:

US Considering Wind Development Offshore New York

The United States Bureau of Ocean Energy Management (BOEM) is considering a competitive lease process for wind energy development offshore New York of New York. The potential project is part of President Obama’s Climate Action Plan to develop domestic clean energy sources, cut carbon pollution, and to create jobs.

According to BOEM, it is publishing a call for information and nominations to obtain nominations from companies for commercial wind energy leases. The proposed location for the leases is eleven nautical miles off the south of Long Beach, New York.

The BOEM reports it is also seeking “public input on the potential for wind development in the call area, which includes comments on site conditions, resources, and existing uses of the area that could be relevant to the wind energy development authorization process.” The call is considered an important step in planning for wind offshore New York.

GlobalData report: Worldwide cumulative wind power capacity to more than double by 2020.

China accounts for the largest single wind power market with 45% share of total global annual capacity additions in 2013.

The global cumulative wind power capacity is expected to grow from 319.6 GW in 2013 to 678.5 GW by 2020, says research and consulting firm GlobalData. This despite an overall slump in installations in 2013.

The report, "Wind Power Update, 2014," confirmed that China remains the largest single wind power market. The country is expected to have a cumulative wind capacity of 239.7 GW by 2020, according to GlobalData. If you recall, China overtook the US as the leading market for installations in 2010, when it added a massive 18.9 GW of wind capacity.

Energy Department Announces New Regional Approach to Wind Energy Information

In order to provide the highest quality information to support decision-making regarding wind energy, the Energy Department today kicked off the collaborative partnership between its new WINDExchange initiative and six supporting Regional Resource Centers.

The new WINDExchange initiative and website will serve as a digital portal providing fact-based informational resources about the costs and benefits of wind power, technical assistance and guidance for simplifying the deployment process, and public access to educational resources. Upholding the Energy Department's commitment to making high-quality information available to advance clean energy technologies, WINDExchange provides key resources and tools through its website such as: wind resource maps; e-newsletters published twice a month; webinars; podcasts; databases; economic development studies; fact sheets; the Wind for Schools Portal; and a Small Wind Guidebook.

Six new Regional Resource Centers (RRCs) will serve their regions as wind energy information centers, supporting WINDExchange's efforts and working collaboratively with local organizations to engage diverse stakeholder groups. Their geographically-based focus will enable the RRCs to better understand and target the specific priorities and challenges relevant to their regions. Leaders from the RRCs are meeting this week at the National Wind Technology Center in Colorado to kick off this year's engagement activities in each region and discuss the new WINDExchange resources available to support their work.

UK offshore wind to meet 10% of national electricity demand by 2020, says new report

The UK is "on course" to double its offshore wind energy generation capacity to 10GW or more by 2020, meaning that the "maturing" technology would be able to supply around 10% of the country's electricity demand, according to the body responsible for managing the seabed.
