The advantages of wind power

An advantage to any community where a wind farm is built is first the employment during construction, then the Community Fund ($50k per year in the case of Clements Gap Wind Farm) that will be there for the life of the wind farm.

Some of the advantages that wind power has over other forms of electricity generation are:

• It is environmentally sustainable.
• There is huge potential for wind farm development in Australia using currently available technology.
• Wind farms can be built with little environmental damage and little loss of economically productive land.
• Wind generated electricity, on a level playing field, is as cheap as most conventional forms of power generation and cheaper than most of the other sustainable forms.
• Unlike 'clean coal' (coal with sequestration), which may be achieved at some time in the future at an unknown cost, wind farms are being built now at a competative cost.
• Mining, concentrating and refining the uranium used for nuclear power uses large quantities of fossil fuels; the 'fuel' for wind farms is free and sustainable. There is no waste from wind farming that is difficult to dispose of and nothing that can be used for nefarious purposes. The lead-time for building a nuclear power station is ten to fifteen years, for a wind farm it is about three years.
• Wind farms, once operating, produce negligible greenhouse gasses. The greenhouse gasses produced in the construction of wind farms are 'abated' within the first few months of operation. Coal-fired power stations are one of the largest producers of greenhouse gasses on the planet; in terms of tonnes of CO2 per GWhr of electricity, oil fired power stations are less polluting than coal and gas-fired is less polluting than oil, but gas-fired power still produces about half the CO2/GWhr of coal.
• Wind farms use a negligible amount of water. By comparison, coal-fired power stations typically use more than a million litres of water for each gigawatt-hour of electricity generated; nuclear power stations and even many of the larger solar power stations also require significant amounts of cooling water.
• Compared to solar power wind farms use little land. (Solar and wind are compared elsewhere on this site.)

The future of wind power in Australia

Wind turbine at Starfish Hill, Fleurieu Peninsula

Wind, at the present, is the only economically competitive form of sustainable energy ready to take a significant part of the load. (Australia's wind power potential is dealt with on another page on this site.) Using biological waste and methane from land-fill to generate electricity is feasible and is being done, but its capacity is limited. It is looking like solar thermal and 'hot dry rock' geothermal is close to being competitive, but these are not ready yet and will take many years to 'scale-up' to the point where they are major sources of energy. Wave-power, photovoltaics, harnessing algae to produce fuels, and other alternatives seem further away. A decade or two could change that picture.

Limits to growth of the wind industry

1. The lack of electricity transmission lines where they are needed (Governments seem willing to build transmission lines to new mines, but unwilling to build them for the large-scale development of wind farms);
2. The artificially low price of Renewable Energy Certificates which is at least partly due to the Rudd Government's dodgy solar credits incentive scheme for small solar power installations;
3. A growing level of opposition to the building of wind farms, which seems based mainly on the NIMBY principle.

Certainly wind power is not 'the answer' to climate change. Only a naïve person would believe that there is a single answer, and only a naïve person would object to wind power because it is not 'the answer'. It is a part of 'the answer'. Other parts are energy conservation, technological innovation, development of other forms of sustainable energy, and education. (I have listed some suggestions in What should be done.)

If the logic in the few sentences above is correct, then wind power must be developed to the maximum reasonable degree and as quickly as possible.

In Australia's wind power potential I argue that the potential installed wind power in Australia is more than 91GW, and the amount of generation then would be more than 241TWhr p.a.

Off-shore wind power installations are also quite possible. Turbines can either be set in the seabed in shallow water or they can float and be tethered to the seabed in deap water. Off-shore developments could at least double Australia's wind power potential. The greatest Australian potential for off-shore wind power is near Tasmania, but all the southern coast of Australia could be used.

Whether all of this potential should be developed is another matter.

Will we get sick of the sight of wind turbines? Quite possibly. The alternatives, it seems to me, are either to throw caution (and, I believe sanity) to the wind and continue with fossil fuels, or to totally change our life-styles and enormously cut down on the amount of energy that we use, in our personal lives and in industry. I cannot imagine our society being ready or willing to do that.

The figures below were calculated from Australian Energy Market Operator (AEMO) data downloaded via the Australian Landscape Guardians (ALG) Net page. The AEMO does not control WA wind farms, and they do not provide data from several of the smaller Victorian wind farms. Graphs of average power generation, on a month-by-month basis, for each of the wind farms in the table below are given on the state wind farm pages, via the menu at the top of this page or the Wind farm index.

The capacity factors and average power outputs were calculated for data recorded in the given periods (inclusive of the starting and ending months). Internationally, I believe, a capacity factor of anything above 30% is considered very good.

Wind farm power generation in Australia

Notes:

• None of the WA wind farms and several of the smaller Victorian wind farms are not included, eg. Codrington, Toora and Wonthaggi.
• Lake Bonney Stage 3 is not included in the total for Lake Bonney.
• While Lake Bonney Stages 1 to 3 have a considerably higher installed capacity than Waubra, Waubra seems at present to be the most productive wind farm in Australia – due to the low capacity factor of the Lake Bonney wind farms. Hallett is a close second, and when Hallett #4 comes fully on-line, Hallett will easily surpass Waubra.

Compare these figure with the installed capacities of major wind farms in Australia.

Australia's record on wind power, on the world stage, is poor.

Germany has one twenty-first the land area of Australia, yet has about 16 times as much wind power (and hugely more solar power). Spain has about twice the population of Australia, a fifteenth the land area, yet about 11 times as much wind power. Little Denmark, with a quarter our population and 0.6% of our land area has more than twice our wind power.

Even the USA, a nation whose federal administration has, in the recent past, been notoriously against doing anything about greenhouse/climate change, has about 16 times as much wind power as Australia.

Australia has huge potential for developing wind power, but has been notably slow in doing so.

The proportion of electricity that can be generated by wind before problems relating to variability of supply become intolerable has been debated for years. The magazine Wind Power Monthly reported that Denmark generated 31.5% of its power by wind in January 2008 (apparently January is its windiest month) and had generated even more in January 2007 (35.5%). Even more important, the article stated that there had been no need to constrain production from the turbines at any time. (I believe that Denmark has the advantage of power-sharing with neaby Norway which has a large hydro-power resource.)

Twenty percent by 2020

Australia's target of 20% renewable power by the year 2020

Old sustainable energy To the time of writing (2009/03/04) I have not been able to find out exactly how much hydro-electricity is generated in Australia annually, but believe that, together, the Snowy Mountain Authority (SMA) and Hydro Tasmania (HT) generate about 15TWhr per year. Installed capacity of all other hydro-generators in Australia is about one third of that owned by SMA and HT, (DEWHA figures) so it is reasonable to assume that generation from them would be about 5TWh/yr; giving a total for Australian hydro-power generation of about 20TWh/yr. (This may be declining because of climate change, reducing rainfall, and hence less run-off and less water to run through turbines.)

The Rudd Government's stated target of 20% renewable energy by 2020 involved adding 20% new renewable energy above the baseline at the time the MRET was promised. If Australia is to reach the target then we will require about 42TWhr/yr of new renewable energy and a total of 62TWh/yr of renewable generation by 2020.

Little new hydro capacity is being built, so we can figure on hydro making up no more than 20TWhr (see the box on the right) of the 62TWh/yr required by 2020. This leaves a deficit of 42TWhr to be generated by technologies other than hydro.

Installed wind power in Australia at the end of 2009 was about 1.9GW. I have not been able to obtain any figures for actual wind power generation for the whole of Australia, but using a capacity factor of 35% we can calculate about 5.8TWhr per year from the 1.9GW installed capacity.

It seems unlikely that forms of sustainable energy other than hydro and wind can make up more than 5TWh/yr by 2020, see Sustainable Energy – Overview. Wind currently makes up just over 90% of new renewable energy, so it seems that if we are to reach the target, wind power will have to fill most of the gap. So, if we are to have 62TWh/yr of renewable energy by 2020 it is likely to be made up of about 20TWhr (old) hydro, wind at least 37TWh, and other probably less than 5TWhr (20+37+5=62).

In Australia's wind power potential I argue that the potential installed wind power in Australia is more than 91GW, and the amount of generation then would be more than 241TWhr p.a.

Will Australia reach 20% by 2020?

At the end of 2009 there are only two wind farms under construction in the whole of Australia! It takes about fifteen months to build a wind farm and there are 100 wind turbines in the two farms under construction, so this equals a contruction rate of one turbine every four or five days; well short of the rate required.

Considering that governments, both state and federal, are providing only limited encouragement for the development of wind power it seems unlikely that we will reach the target; unless our total electrical consumption is substantially reduced and the only way that would happen would be some sort of catastrophic economic collapse.

Small wind disadvantaged against solar

This produces an unfair discrimination against the small-scale wind industry. Why would you pay full price for a small wind turbine when you can get a $7500 rebate on solar?

Wind turbines and sailing ships

Both sailing ships and wind turbines are graceful and are works of art, while steam ships and fossil fuel power stations are simply practical and are means-to-an-end.

Both sailing ships and wind turbines are sustainable; steam ships and conventional power stations are not, because of the finite reserves of fossil fuels they burn and the damaging carbon dioxide they dump into the atmosphere.

To anyone who says that a wind turbine is not a work of art I would say go and stand in the middle of a modern wind farm and watch while the sun sets. If you go with an open mind you cannot help seeing their beauty and grace: quietly powering our energy-hungry life styles while doing very little harm to the environment. I don't mind admitting that they fascinate me.

Ironically, steam ships replaced sailing ships, yet wind turbines are, to some extent, replacing fossil fuel fired power stations. With greenhouse and the approaching end of oil, will we one day see the return of sail?

The number of homes supplied by a given wind farm

Company	No. homes per MW	Wind farm
AGL	570	Brown Hill Range (Hallett)
Acciona	740	Waubra
Epuron	400	Broken Hill
Pacific Hydro	500	Challicum Hills
Roaring 40s	500	Woolnorth
Verve	700	Albany
WestWind	571	Lal Lal

Why the variation? Perhaps it is due to the perceived quality of the local wind resource, perhaps it depends on how much power households use in different regions, perhaps it is only due to variations in the estimations of company public relations people?

The numbers above vary from 400 to 740 homes per installed megawatt. If we assume a 35% capacity factor we can calculate that an installed megawatt will generate 350kW on average. If 350kW will supply 400 homes then the assumption is 875 Watts per home; if it will supply 740 homes then the assumption is 470 Watts per home.

How big can wind turbines get?

As of December 2009 the largest wind turbines in Australia are 3MW (3000kW) which are being used at Lake Bonney Wind Farm. These have steel towers 78m high and fibre glass blades about 44m long.

Roaring 40s are considering 3.3MW turbines for Stoney Gap and Robertstown wind farms.

The technical challenges of lifting loads of nearly 100 tonnes (the Nacelle, including gearbox, dynamo, cooling system, etc.) to heights of around 80m are considerable.

In some European off-shore wind farms, turbines of 6MW are now being used. They have blades of up to about 65m long (the wingspan of a Boeing 747-400 aircraft is 64.67m – that's the length from wingtip to wingtip). When assembling these turbines, instead of raising the whole of the nacelle and its contents in one lift, as has generally been done in Australian wind farms, I believe that the main components of the nacelle are raised in separate lifts for these very big turbines.

The limit to the size of a wind turbine seems to be in the size of the crane needed and the difficulty of lifting very heavy loads to great heights.

Energy return on investment (EROI)

Importantly the EROI for petroleum is declining as more wells have to be drilled, more pumping done, more high-tech processes used, to obtain the same amount of oil.

It has been suggested that if EROI for our most important energy sources gets down to 10:1 it will begin to have a heavy impact on the modern way of life.

Studies on EROI for many of the energy industries have been reported on The Oil Drum and in particular Dr. Cutler Cleveland and Ida Kubiszewski posted an article describing a meta-analysis on the EROI of wind power on The Oil Drum.

From Cleveland and Kubiszewski's data the following can be extracted;

Energy return on investment for wind power
Country	Number of values recorded in each country	Average EROI
Belgium	2	29
Denmark	12	28
Germany	28	17
Japan	9	10
Switzerland	2	4
USA	4	20
Overall average		18

It should be noted that there is a huge range of EROI values, indicating that the industry is not mature. As the industry matures businesses will learn to develop wind power in areas and using methods that maximise the EROI value.

Cleveland and Kubiszewski calculated an overall average EROI of 18.1, placing "wind energy in a favourable position relative to conventional power generation".

Unfortunately, Cleveland and Kubiszewski's data did not include any information on Australian wind farms. ESIPC (SA Electricity Supply Industry Planning Council) does not record EROI figures for South Australian wind farms.

Kurt Cobb has posted on EROI in the Energy Bulletin. Some of his figures for energy sources other than wind are in the table below (I added wind):

Energy return on investment
Energy source	EROI or Range	Comment
Wind	Around 18	See above
Crude oil	Around 20	Conventional
Tar sands	1 to 7	Figures vary greatly
Coal	80	but falling
Nuclear	2 to 11	Figures vary greatly
Solar	?	Figures vary greatly
Hydro-electric	very high

EROI x Scale for fossil and renewable energy sources

EROI against total energy

The original of the figure was posted on the Oil Drum. It relates primarily to US data.

The distance the balloons are from the bottom shows increasing energy return on energy invested. The distance from the left shows increasing power obtained from that source.

Denmark successfully produces some 20% of its electricity by wind farms and plans to increase this to 40% in the future. The Danish Wind Energy Association has confirmed (pers. com.) the need for detailed wind forecasting if a large component of wind power is to be used. Denmark has the advantage of being part of a large European power grid. Australia, on the other hand, has the advantage of being much bigger than Denmark; a wind change on the west coast of Eyre Peninsula will take a long time to affect wind farms in Victoria or eastern NSW.

The rise of the world-wide wind industry has caused a very competative wind forecasting industry to follow. At present, I believe, wind forecasting in Australia is produced by a single organisation and the forecasts are distributed to all interested parties. It has been suggested that "this discourages competition by being centrally produced and a better solution is a central forecast that is NOT distributed to participants. That way the system operator gets a forecast and they should also require operating schedules from the wind plants – not ones that are as strict as fossil fuel operating schedules, but something none-the-less. This is good for everyone – except maybe the incumbents.

1. Competition will force down prices (if the prices are inflated too much) – we bring our same pricing structure as we use in the very competitive US market.
2. Competition will force the forecasters to continue to improve.
3. The system operator will get a system wide forecast (very useful) but will also get project specific forecasts that are tuned to each wind farm and will likely be more accurate for that wind farm (which in turn helps scheduling transmission).
4. It helps get more wind onto the system as it will be better forecast and easier to control (i.e. there will be an expectation to meet schedules to some extent). This will allow for higher wind penetration."

In regard to the way that wind forecasts are produced, I am informed that: "In a VERY high level overview, good forecasts are created using numerical weather prediction [NWP] models which use global models as inputs (e.g. Global Forecast System) which are derived from observations all around the world. This is the best method 6 hours to almost a week ahead. Shorter time frames use some kind of local observation-based system. This approach is best up to around 6 hour out – primarily because the NWP models take so long to run that they are out of date by the time that have finished operating (and you can get better information by using local observations). The exact overlap of usefulness depends strongly on the location."

Much of the above couple of paragraphs were from a person in the wind forecasting industry who didn't want his/her name published. If others in the industry can add more, I'd be please to hear from them.

Community investment in wind energy

40% of local residents have invested in the Galmsbüll "Citizens' Wind Farm"

Community investment has helped Germany to become the most successful nation for wind power in Europe. At Marienkoog in the North Friesland region, dozens of local people have taken a share in their local wind farm and watched the turbines being constructed for the benefit of the neighbourhood.

When the older wind turbines at Marienkoog were replaced by fewer more powerful models, the local community was offered a third of the shares in the 'repowering' project. Altogether, in the Galmsbüll Bürgerwindpark (Citizens' wind farm), of which Marienkoog is part, a total of 240 residents invested 5 million euros. This represented 40% of the district's adult population.

One result has been general acceptance of the new taller wind turbines in the landscape of this mainly farming region close to the North Sea coast. The local council also receives income from the business tax paid by the wind farm.

Payments to land-owners

There may be a once-off payment for access, and there usually is an annual payment per turbine. Some years ago I heard that a typical payment for one turbine was $4000 per year. More recently I had a confirmed figure of $7000 per turbine per year for one wind farm (the company didn't want it to be commonly known, most of these deals are 'confidential'). I have recently (July 2009) heard, second hand, unconfirmed, that some wind farmers are paying $12 000 to $14 000.

Farmers should, for their own protection, make sure that the agreement that they sign does not leave them liable for decommissioning the turbines at the end of their useful life. Depending on how the decommissioning is done, it could be very expensive, especially if nearby native vegetation has to be protected in the decommissioning process.

Wind power in territories

Australian Antarctic Territory Wind Farm

Two 300 kW wind turbines were installed at Mawson in 2003 and now make a significant contribution to the station's power requirements.

The Mawson wind turbine system ranks among the world's most innovative, and is capable of providing 600kW of renewable power. Australia is the first country to obtain a significant electricity supply for its Antarctic stations fuelled by the most powerful winds on the planet.

Studies in the early 1990s revealed that the constant katabatic winds blowing from the inland of the continent make Mawson ideally situated to generate the bulk of its energy requirements with wind turbines.

The AAD worked closely with a German turbine manufacturer (Enercon) and an Australian company (Powercorp Pty Ltd) to install the turbines and the associated computerised powerhouse control system in early 2003.

I thank Lee Sice for allerting me to the AAD net page on the Mawson wind farm.

Footnote on AGL My personal experience with AGL is not a happy one. I installed photovoltaic (solar) panels on my South Australian house. AGL were legal obliged to pay me $0.44/kWhr for the power that I fed into the grid from July 1st 2008, but they did not until about October of that year. In spite of many attempts to get the payments out of AGL, and contacting the Energy Industry Ombudsman on the matter, AGL have never paid what they owed. They also changed my supply back from green to brown electricity without my permission.

Wind turbine art   Photo by Klaus Rockenbauer. More of his photos are on Flickr. Here is something that has, so far as I know, never been done in Australia; a wind turbine used as an art form; or you could say, as a canvas on which to mount a work of art. Klaus Rockenbauer placed a copy of the photo on the right on Flickr. It is of an Enercon turbine in Munich, Germany. Klaus said: "On the blades of this wind turbine were placed about 9000 LED's. They draw motives in the night sky every day for about 7 hours. This art-object should be a sign to the energy problem worldwide and also is the biggest Christmas-star of the world." The Osram Net site has a page on the turbine: "Right on time for the first Advent Sunday it is obvious to all: But still it moves! Siemens – together with multimedia artist Michael Pendry – has lighted up the world's biggest revolving Christmas star. The lighting installation can be seen throughout December [2009] at the northern gateway to Munich – beginning at dusk every evening." The entire installation uses only as much electricity as a hair dryer or a water kettle, yet in good weather it can be seen for 30 kilometres. A similar thing could be done in Australia. It could have the potential to make turbines more of an attraction than they are at present.
