Which way will wind power blow?

By nearly any metric, 2011 has not been a particularly good one for Vestas, the world’s biggest wind turbine marker. Lower than expected demand for wind turbines, and fierce competition from rivals, particularly in Asia, has pushed the company to a third quarter loss and forced it to abandon its long-term financial goals – its so called Triple15 plan of €15 billion in revenue and an EBIT margin of 15 per cent by 2015. The outlook – clouded by the sovereign debt crisis in Europe, a slowdown in wind turbine development in China, and the likely removal of a crucial tax credit in the US – has helped push its shares down 55 per cent in the year and nearly 90 per cent from their 2008 peak.

Vestas CEO Ditlev Engel, however, says that the best days of wind are not over. In an interview with Climate Spectator, Engel says the Danish company can match the Chinese (and says it already sells more turbines in China than the Chinese sell outside of their country), and will play a critical role in future energy needs.

Engel says Australia has a magnificent wind resource which is as valuable as the resources that lie in the ground. But it is unlikely that Vestas will consider reopening the wind place and nacelle assembly plants it closed a few years ago.

He also says gives his views about technology development, and how the youth of today will have a different approach to energy than the current generation.

Giles Parkinson: Vestas is the world’s biggest wind turbine manufacturer. Just a week or so ago you announced losses for the third quarter. You’ve signalled that you’ve abandoned your long-term financial goals and your shares are down quite sharply. Has wind already seen its best days?

Ditlev Engel: No. Absolutely not. I think what we said the other day was because of the two main reasons: the sovereign crisis, predominantly in Europe; plus obviously the fact that there’s a lot of uncertainty in the United States in 2013 concerning the extension of the PTC (tax credit) could pose a challenge. But we, actually, at the same time, said just the reverse; that we still believe that the long term outlook for the wind sector is still very strong, but since, for instance, we have about a half of our business in Europe could be more impacted.

GP: You also face immense competition from Asia, particularly from Chinese wind companies. I guess to guarantee your long-term future you’ve also got to make certain of your short-term future as well. Are you confident you can match the Chinese?

DE: We have to remember that Vestas has 3000 colleagues in China and we went into China in 2006 and we built a number of plants there. That means that if the rules of the game going forward, for instance, are that everything should be used in China and shipped around the world, Vestas can definitely do that as well. Now, because of the magnitude of the products, but also, of course, the transportation costs, etc, etc, we don’t think that’s really going to happen. But actually, if you add up the numbers, if you look at 2010, Vestas sold more megawatts in China than all of the Chinese combined sold outside China.

GP: If you can’t beat them, join them, as it were.

DE: Well, China is of course the world’s largest wind market, but if you look just here in 2011, I think we have already seen that the Chinese market has not grown to the level that it had done in the previous year, so I would say it’s getting into a more a normal stride now going forward than the very steep road that we saw just over the last few years.

GP: Both Denmark in wind and Germany in solar have invested a lot to encourage the development of the wind and the solar industries in their countries. Part of that was justified by the fact that they would create a manufacturing base in their own countries. Do you think those strategies will ultimately prove successful or will those manufacturers inevitably disappear overseas into cheaper economies?

DE: I’m not going to comment on solar because that’s not my home turf, so I’ll speak to the wind side of the business. And I would say, seeing from the wind point of view, I think one of the very important issues for us has been to globalise our business. And if we had not set up a global business as we have done now, we would have been in a very challenging position. We have five million people in Denmark and a very small country, so I think it’s nothing unnatural about the fact that we are globalising it. The wind sector has created a lot of jobs in Denmark and especially in the research and development, and now the Danish government has just increased its targets, so I’m sure that we’ll keep on seeing this development.

And just to give you an idea of how important it is, talking about China, we have just made a huge study on how you actually balance the grid much better going forward ...which is obviously a very important knowledge that we have built over the years in Denmark, thanks to the very heavy focus on integrating wind into the totality of the energy system.

GP: I’ll get on to the balancing issue in a minute; you mention in your presentation – that was presented two weeks ago – you had a vision; wind, oil and gas. What you mean by that?

DE: We are 22,000 people in Vestas, and I think it’s very important that we all understand wherever we sit on the globe. And the focus when we say wind, oil and gas is really to position wind as an energy source on par with oil and gas. This means the performance of the turbines, the reliability, and the grid integration is very important. Oil and gas is going to be the base load for decades to come for the world. We all know that. And therefore it’s also very much a question of how do we incorporate with the existing energy sources. And if I just look at what has happened since 2005 until today, Vestas’ customer base has changed dramatically from small-, medium-sized developers, into some of the largest utilities in the world – and I think that’s another way to signal our vision, namely that we have to develop this energy source going forward.

You then look at it from a cost of energy perspective and then wind is by far the cheapest of the alternatives on the table and thereby it makes more sense to make wind as the natural partner of the existing cost of fuel going forward because we keep bringing down the cost of energy and it can be integrated with the existing technologies, which we have shown in Denmark. You know, with Denmark we get more than 20 per cent of our electricity from wind and it’s going to get up to 50 per cent, so it is the main part of the energy sources going forward.

GP: Well, let’s go back then to the balancing question, because wind is criticised still a lot for its intermittency, that it doesn’t serve its purpose, and some people say we’d better off without it. How do you respond to that?

DE: First, we have to look at the macroeconomics... Normally when people ask me this, my first question I always ask back is: Ok, if you don’t want to do wind, what do you want to do? When you just say no, you have to come up with an alternative. We know the energy sources in the world are going to come under tremendous pressure. Three comments which came out of the International Energy Agency the other day, which is obviously one of the, if not the most respected commentators on the energy business going forward; they came out with a few, I think, very important messages. The first message is that we will soon go from $US100 to a $US150 per barrel of oil - the days of cheap oil of $100 per barrel are over. That’s the first point. The second point is that in Copenhagen the world leaders agreed that we have to keep the temperature increase below 2°C, because otherwise the costs to societies would go up dramatically.

According to the IEA, if we don’t start to change our carbon footprint, then by 2017 the world will pass the 2°C and then the window closes forever. And therefore, they said, any dollar that you do not invest today in making the new energy development will cost you… after 2020 will cost you $US4. And don’t take it from a wind guy, like me. Take it from the IEA. Politics has a very important role to play because I think it’s the job of the politicians to look at what are the costs of energy to society, short, medium and long term. And therefore, when people say to me, now we don’t want this turbine, we say fine, how will you then deal with these other very serious macroeconomic challenges?

GP: But how confident are you that the politicians will actually respond to the challenge, then, of lowering emissions? Because they’ve talked about broad targets, but are they actually implementing those policies? They are still a long way from those policies and I think that was the fundamental point that the IEA was making as well.

DE: But you know the day before yesterday in New York we unveiled the criteria for our Wind Made initiative that we have done together with a lot of major corporations in the world which we launched, actually, back in January. Now, we’ve set out the criteria. What we believe – and we can see from a lot of the consumers polled all over the world, also together with major companies – is that the sustainability issue is still very much at the forefront of the consumers' minds. We can’t just rely on the politicians, you know, to solve everything, because we need to make sure that we all… that people can, sort of, on a broader base, see the picture here. So, I think there are other issues at the table.

 If I could just comment on the political side, let me say I was chairing a green growth working group at the G20 in Seoul and I was chairing the same theme with a group of different companies at the G20 which was conducted in Cannes in France just a few weeks ago and the interesting thing is when you talk to business from all over the world, as I had in my working groups – very big companies – they all say the same thing; we know exactly what is needed in order to move green growth forward. And the first one, and this is of course where we are very happy to see what has happened in Australia, is to put a price on carbon. Secondly, we need to remove some of the trade barriers that are in green growth. Thirdly, we have to scale out the renewables. And fourthly, we have to stop subsidising fossil fuel, which is running at a magnitude of $US400 billion a year. And these were included in both of the G20 in Seoul and the G20 in France as recommendations from heads of state. And therefore I have to say I have to give a lot of credit to Australia for actually going out and actually delivering on the agreements made at the G20.

And I have to say, I’ve been very encouraged. Just to give you an example, I sat just two weeks ago and watched the president of Mexico, President Calderon, giving a presentation with slides on how ...[failing] to act now on turning Mexico into a green economy ...will cost Mexico, in the long run, much, much more. So, obviously it’s very important for the political leadership, but of course I think also to make people aware of what are the real costs, as per Mr Calderon did the other day in France. …Because people can understand that. I mean I think everybody can understand what the IEA says. If it’s one to four, I think that’s a calculation most of us can understand.

GP: On the question of subsidies, the wind industry is criticised a lot for relying on subsidies to build wind turbines. Notwithstanding that you think that there are more subsidies going to fossil fuels, but when do you think that the wind industry will be able to stand up without subsidies?

DE: You know, the question of subsidies and the costs of energy has to do with what does it cost society. And the key question is, do you measure the cost at the meter or do you measure the cost of the total costs for the taxpayer? And I can tell you, for instance, in Denmark, we have made a calculation because we have a lot of oil and gas coming out of the North Sea. We made a total calculation of what will it cost a Denmark to become 100 per cent fossil fuel free and the cost to GDP to run Denmark entirely on wind would be 0.5 per cent of GDP.

Now, we would obviously pay more for the electricity, but then we will save a lot on health care. We would save in a lot of other areas which, of course, society has to pay anyway. When people say to me, what is grid parity, then the only way to answer that is you’ve got to make a calculation for society. I know that in Colorado, one of the states in the US, they made the same calculation – because they, like your country here, have a lot of tourism and they used to be a big coal state – and they found out that, with the cost of coal, it actually ended up they were paying a lot of money for cleaning up their lakes, their rivers, in order to make the tourists happy. They actually found out that they had a lot of wind, so in making Colorado much, much greener, actually it looked like a higher cost per kilowatt hour, but if at the end of the day you looked at the total cost of Colorado, it was actually a better deal.

GP: Let’s talk about Australia. A few years ago you had a blade manufacturing plant in Australia. You had a nacelle assembly plant in Australia. Under what circumstances would you consider having such plants in Australia again? Will that never happen?

DE: Well, coming back again to the cost of energy ...How can we, in the most cost effective way, deliver our products to Australia? We are building the largest wind farm right now called Macarthur in the state of Victoria and there we are getting the blades and the nacelles are coming from Denmark, but the towers are being produced in Australia. So, we try to look at what is the most optimal. The reason why we closed down the plants in Australia was because of the lack of longevity in the planning and, at that time, there were no signs that Australia was going to embrace wind again, which obviously has changed now. So, it’s all got to do with what is the the best business case for Australia. So it will depend on the size of the market, but at this moment I think it will be cheaper for Australia to get at least part of the turbines outside Australia, instead of making them here. So at this moment, we don’t have plans to reopen those. It was a great shame. We took it up at the time with the government before we took the decision, but it was just not possible.

GP: In Australia we have a lot of sunshine. Do you see wind competing with solar in Australia and how do you think it will match up?

DE: The discussion between wind and solar, I think we’re going to need all of it, because the energy challenges of the world are so huge that ...I think we’re going to need anything we can come up with. Just the other day we passed seven billion people on the planet and we are going to have another two billion people in the next 25, 30 years, so the pressure on resources is going to be massive. Which I guess is exactly the reason why the economic outlook for Australia is so strong, because you are a society very much relying on all of the resources that you can export to the rest of the world, which I guess is good news from an Australian point of view, but it again means that from an energy perspective the cost of energy is going to be under significant pressure upwards. And I think we’re going, you’re going to need all of it. But if you look at it today, from a cost of energy perspective, then wind is significantly cheaper than solar now, but actually solar is going to reduce their cost as well in the coming years.

GP: Where do you think growth in the wind market is going to be? Is it going to be in onshore or is it going to be in offshore?

DE: In Australia, you guys have so much land, so since it is much cheaper to install them onshore instead of offshore, then I’m sure that onshore is going to be the name of the game in Australia. And you also have to remember that the onshore wind resources you have in Australia are phenomenal. I mean, again, a lot of people know that you have a lot of resources in mining and so on and so forth. Having fantastic wind resources onshore as you have in Australia is as good for the future economic security as having a lot of resources in the ground and you just have them up in the air as well, but people don’t think about it this way.

GP: Sure. Can you tell us about the size of the turbines of the future? Will they continue to just get bigger and bigger or will there be…?

DE: I don’t think so. From a transportation, cost efficiency point of view, I think we are at the peak now. The turbines we are sending for Macarthur are called the V112 which is I think sort of the largest we are going to see. And for practical reasons, shipping reasons, transportation, I think we are at the edge, now, onshore. I think we’re going to get bigger and we have for offshore; we have a launch that’s a seven megawatt turbine, but that is so large that it has to be manufactured at a port very close for installation, so if you’re going up in that scale, you need to have a significant offshore market just around the corner like, for instance, we have in the UK.

So, I think we are at the peak now, and because of the cost of materials, the lighter you can make the design, the smarter you can make the design and thereby reduce the consumption of materials, the more you can lower the cost of energy. So, in the old days it was about, you know, making them just bigger and bigger. I would say going forward it’s about keeping them at this size and then keeping making them lighter, because that will keep on checking out the total cost of the manufacturing.

GP: Will there be a complete step change in the way that turbines look, big three-bladed machines?

DE: I’m not an expert in this area, but I can tell you that we have tried so many different versions, two, four, whatever, and I think it’s going to end up a bit like a car, you know. They’ve been running on four wheels for a while.

GP: Yes. Fair enough. Can you give me your vision of what the energy map of the world will look like in 50 years’ time?

DE: In 50 years’ time?

GP: Yes.

DE: Wow. That’s a tough one.

GP: Ok, 20 years then.

DE: But even that… Well, I will put up a disclaimer and then I’ll give you my best shot. Walt Disney once said if you can dream it, you can do it. And where I really put a lot of hope on is the fact that all the people who are very, very into this debate see the future of energy and consumption in a very different light compared with the elderly generation. I think that the younger generation is going to push this agenda much, much harder. This is something we are polling on a global scale, and therefore I would say I think in the next 20 years I think you’re going to see companies and future leaders embrace sustainability and a new energy debate in a completely different way than we have done in the past. Young people today have a different perspective than the rest of us, which I find very encouraging, so I’m sure they will do a good job here.

GP: Does the view between young and old, does that explain a lot of the push back against wind that we see around the world at the moment, just in commentary? Wind does come in for a lot of criticism for one reason or another.

DE: The other day one of the heads of state at the G20 said you know, all history has shown that the best ideas start out with somebody starting to embrace it and then they develop over time. And I think one of the most important jobs we have to do in the renewable sector is to work with people and explain to them what are the myths and what are the facts and keep having this debate. And if people have challenges, if they’re anxious about the issues concerning wind, if they think that [wind farms] in some way are problematic to deal with, the best we can do is to have a dialogue about it. As I said before – ok, if we’re not going down this route, what should we then do, because we know we have to change. And therefore I think we have a very important role to make sure that there is public acceptance.

So, I think that’s going to be very important, also, coming back to the outlook for the next 20 years. If we can explain what are the pluses and the minuses associated with our type of technology, then I think people embrace that. And then I think there’s one thing we should not forget, and that is that technology always seems to change everything. We have a lot of close cooperation also at universities in China, so if you just imagine, for instance, that some of the issues concerning storage; there will be some breakthroughs there. You’re going to see the whole energy sector change forever. So, I think we have to remember, you know, that we are starting to say: ok, what happened in the mobile phone sector 20 years ago, well then some people might have said, well, maybe every household will have two phones, and it ended up with everybody has a phone with a tremendous capacity. We have to remember that there will be a lot of things coming from technologies that may be impossible to envisage today.

GP: Terrific. I do thank you for your time.

DE: Thanks very much. Nice talking to you.

Wind farms a misnomer

The wind industry will have you believe that you are against turbines because you are not hosting them and therefore are not receiving an income from them.  They are not windmills as some seem to think but industril turbines. They cause CO2 emissions with their construction, destroy the environment,kill fauna and destroy flora, they do cause some people health issues and if they were so wonderful why are people walking out of their homes? They are costly, inefficient and rely on some other source of power when the wind does not blow or is too strong and have to be turned off. Denmark sells off their wind power and import electricity from other countries. German in 2009 only got 7% total and yet they are the biggest consumers of wind energy. What is wrong with waste to energy, geothermal and nuclear (although with Japan not likely yet France has many nuclear plants without incidence). Many experts from overseas now state there are problems with windpower see europes ill wind for one, D. M. Swinbanks (former NASA scientist), Dr. John Etherington and there are so many more.  You cannot store any excess wind energy and turbines actually take from the grid when unreliable weather is afoot because the generators have to keep turning.There is also now according to a spokesperson in the USA that they have a 99% CO2 emission free coal-fired electricity plant. So why can't we do the same?

 

Anecdotal evidence seems to be flawed..Reply to David leComte

 

 

Hi David ,

As soon as someone begins with " I don't mean to offend you...."............ then they obviously do !

 

 

 

 

Anecdotal evidence tends to be flawed

In response to George Papadopoulos:

I dont mean to offend you Giorgos, but such anecdotal evidence seems hard to believe.

I remember similar scares regarding power lines, all of which were proven again, and again, to be not based in fact.

The reason that all clinical drug trials include a significant portion of people that are given placebos is simple.  It is almost always found that there are positive health impacts for those given the placebo.  The positive health impacts of those given the real drug have to be better than the improvements of those given a placebo, in order to have the drug approved.

The placebo effect is well known - convince someone they have been given a drug that will help them, and then they miraculously get better.

Well the opposite is true.  Tell people that something will make them sick, and sure enough they get sick.

The mind is a powerful thing, and is not something we can always control.

I suspect, Giorgos, that you are only suffering from mild NIMBY-itis.

"We will save a lot on health care" - and pigs will fly!

There is a flawed assumption that wind turbines cause no health problems. Ever since the latest lot were installed 35km away east of Yass and around Lake George, I can hear them and they cause me much tinnitus, occasional sleepless nights and predictably severe agitation at times.

I have spent four weeks at Wallerawang 4km from the local coal plant. The local coal plant didn't cause such problems. I was just worried about the locals inhaling in all the soot and emissions and the long term risk of cancer and respiratory conditions - but didn't see anyone go psycho over any noise or sleep deprivation issues.

And of course it was the first time in my life I met a coal plant. The story is very different with turbines - they are going up everywhere like mushrooms - good luck to those who need to find a place to escape their hazards, myself included.

Which way will wind power blow?.... Currently, in our face

Continental transmission lines have many advantages

That the technology exists is clear.  The Xiangjaba-Shanghai link is 6.4GW, and over 2000km long.

Whether or not it is affordable, I cannot say.  I have seen various costs, but I suspect they are higher than what we read.

The principal advantage to long haul links is the ability to smooth the spot price of electricity.  The more players that can contribute to generation, the less price spikes will be.

In a recent article on this site, spot prices in Victora exceeded $10,000/MWh during a recent Melbourne heat wave.  In the article, it said that something like 20-25% of power costs in a year are spent in 36 hours over the year.

Giles, can you provide a link to this article, in case I've mis-remembered it?

If we could get more power, in this example, down to Melbourne from Qld, or across the Nullarbor, or from dams in Tasmania, then these excessive price spikes could be lessened with great savings to everyone.

With a 150 minute lag between Sydney and Perth we could smooth the diurnal load pattern significantly, reducing the peak capacity needed.

Whether power is generated by nuclear means, wind, solar, or even coal power, there is a great economic benefit if that power can be shared over a vast area.

Combined cycle gas turbine CCGT technology, as proposed by the UNSW, does seem to be a great complement to wind and solar.  It can be turned on quickly and turned off quickly.

There are reports and then reports

In response to John Bennets:

One can look at this matter objectively. For example please look at: www.stanford.edu/group/efmh/winds/aj07_jamc.pdf or one can look at similar data with a hidden agenda: http://www.renewableenergyworld.com/rea/news/article/2011/04/geographic-...

A high pressure system can be several thousands of kilometres across, so why would anyone be surprised that aggregation over an area of less than 1000km shows short-term smoothing, but diminishing returns (for smoothing) when the number of windfarms within a 1000km sphere is not much more than 5.

We can trade reports till the cows come home.

Ultimately it comes down to the bias of the person writing and/or reading the report.

Well John, you believe that nuclear power is our only option. I believe in wind, solar, and nuclear power. I do not believe it is possible to address our needs in the next 30 years without recourse to all three. (If geothermal proves useful, or wave energy, then I'll jump on either of them too).

Right now, solar is very close, and wind and nuclear are both mature technologies. In terms of the latter, though, I would prefer us to invest in Gen IV technologies such as an IFR reactor.

John, you really need to start thinking about what we can do; not beat up anyone who isn't just nuclear, nuclear, nuclear. Surely you realise that even if we embarked on an ambitious nuclear program today, we couldn't make a serious impact on coal for several decades.

Wind is part of the solution

Not quite sure what to make of John Bennetts posting. Just because David leComte's vision of continental transmission lines might be "tripe", doesn't make wind power a material and relatively economic addition to Oz power grid.

Wind just needs back up, which is obviously gas. The same applies to solar PV (and solar thermal).

The solution to lower carbon electricity in Oz will not be one "wonder" solution, but a mixture and that mixture has to be relatively cost effective. By moving to around 50/50 renewables + gas, Australia could reduce its CO2 output from electricity production by around 60-70%, at a phased in cost that is affordable and with technology that is commercially proven. By all means if wind and PV costs keep falling then have higher renewables %. If solar thermal (or wave) get past prototype stage at affordable cost then add them to the mix).

Instead, due to the loonies of the right and left we are either going to get "business as usual" or some sort of $350 billion "bet the house on one technology" experiment.

What most people miss in this debate is that to make meaningful progress in reducing Oz CO2 output from electricity we don't have to invent nirvana or take huge risks with hundreds of billions of dollars. All we have to do is do what we have been doing but a lot better, ie. more CCGas, more wind, more house PV. But there also needs regulatory staged closure of all coal power stations.

Which way will wind power blow ?

 

 

Wind turbines do have a place in power generation, an expensive one ! ........And a noisy & ugly one as well !

The best location for them is far out at sea over the horizon  !  Preferably blighting someone elses view !

One aspect of wind-power that I hope will be utilised in the future is the effect of wind on water.........waves.   I think wave generation of electricity is far more practical as it is continuous & the energy is transmitted over vast distances & has the effect of "smoothing out" the supply so dear to David leComte.

Using intermittent power to pump water to high levels for future release in a smooth , reliable hydro-electric power scheme seems a sensible way to utilise an otherwise unpredictable power supply. However,there is a loss of efficiency & increased costs at every stage. If you don't care what it costs then all things are possible , but hardly practicable.

 

Geographic wind smoothing is a dangerous fallacy.

@ David leComte:

OK, we all know that David believes that a bigger grid will somehow smooth over the fluctuating inadequacy of wind generation, but where is the study demonstrating that this is so?  Where are the costings for the hugely expensive non-existent high voltage DC powerlines connecting these far-flung corners of the globe?

Since David has not provided any hint that his advice is other than wishful fantasy, I will provide a link to a very good study which demonstrates that even if Denmark, Australia and so forth were connected by perfect transmission lines of infinite capacity, wind's unreliability problem would not be solved. 

David's contribution is exactly the kind of unsupported tripe which is preventing effective action against anthropogenic climate change.  In what other field would proponents say that they know that what they are doing is fatally flawed, but that if they were only able to repeat the error on a wider scale, the problems would go away.  They would not.

Aggregation over a large area is the key to wind power

Wind + solar + gas/biofuels is definitely a viable medium term option.  The gas turbine technology proposed by UNSW could be the ideal companion to wind and solar?

But wind (unlike solar) can provide baseload power on its own.

This can be done with a sufficiently large grid.  Countries such as the USA, Australia, and Russia, are big enough to aggregate wind over an area larger than the largest high pressure system.

Everywhere else has to fight the parochialism of national borders in order to establish a proper grid.

It is a pity that those establishing our constitution could not see that the grids being laid down in New York etc, at that time, would eventually criss-cross whole countries.

Understandably that would have been considered science fiction in 1900.

The result is that even now, the ability to transfer power across state borders is woeful.

It is time, now that state governments are divesting themselves of control of their own grids, that the Federal government starts to take some control of the mess.

Even without the idea that a national grid could be used to smooth out the supply of wind energy, consider the advantages of being able to smooth peak loads between East and West; use spare capacity of Hydro in Tasmania to supply peak loads in Brisbane in a heat wave up there; or storing power in Tasmania via "pumped storage" during the night.  [We do have a DC link to Tasmania, but it has a peak capacity of only 0.6GW]

Wind and other renewables vs fossil fuels

I, too, was horrified at the blase apparent acceptance that gas and oil will be baseload fuels for decades. Yes, politicians and shock jocks can't see beyond the current economic system, but if climate change is to be limited, we have to shift away from fossil fuels much faster.

Gas, if used locally, is less carbon polluting than coal, but if liquified and exported, it is worse than coal because of the energy needed to refrigerate and compress it!

Oil is becoming more and more limited and because we use it for so many important products other than fuel, it is criminal that we burn it!

And 'clean coal' doesn't exist yet, and even if it eventually is developed it will probably only suit a percentage of power stations because of geological and other factors.

So we need to look at technologies already proven like solar thermal which can meet the baseload requirement considered so important.

Also smart grid and other systems can markedly reduce our demand for electricity.

So please, don't accept the need for oil or gas - there are better and ultimately cheaper ways, esp if you consider the whole cost as expressed by the interviewee.

wind power is not unreliable

John Bennetts, wind power is not unreliable, it is intermittent, or maybe variable is a better adjective. From what I have read on regions with large % of wind you can fairly accurately forecast ahead on wind's likely generation level.

But you do need storage, or backup to make up for the days when the wind isn't blowing much. However the key point is that you can forecast this with a reasonable degree of accuracy.

Personally I would rather go with gas as backup until the next 20-30 years brings the technology and cost improvement in power storage the world needs to go 100% renewable. But others have different views.

You make the same mistake as many other commentators on this site in thinking that we have to have the 100% perfect thought out solution before we can do anything. Instead the most important thing is to be heading in the right direction. To me wind + solar PV + CCG are all heading the world in the right direction to ditch the coal age.

 

Which way will wind power blow

The Netherlands are unloading the costs of wind power unto the taxpayers. That is something, as this is a very windy area and costs should be the lowest of any country. So I conclude that wind power is uneconomical as long as storage is not feasable. Why not use potential and kinetic energy science to store energy and reuse it, such as in reverse water dams ? At least you keep the water and a percentage of the stored energy. Just a thought.  

Wind => oil and gas baseload.

Quote: "Oil and gas is going to be the base load for decades to come for the world. We all know that."

Not true.

How can coal and nuclear be ignored, when one or both are the baseload fuels of China's and many other of the world's grids, the true baseload of the world's energy supplies?

This man has seen his company's shares tumble 90% and his workforce heading downwards rapidly as his market share shrinks.  Of course, he would favour comparisons with oil and gas, both of which are more expensive than wind on an energy basis, but are capable of balancing the unreliability of wind during the 70% or more of the time that it is not generating.  Oil and gas are the lion's share of a wind market, but at present nuclear and coal are still cheaper. 

Even this interviewee indicates that 50% wind is going to be a challenge and that 100% wind is not achievable yet.

Is a switch to 50% wind + oil + gas OK for the world's future?  I think not.  The important question is what the second 50% will be, and at this stage, storage via either batteries or pumped hydro is not the answer.

Perhaps wind power, through being unreliable, is as much a part of the problem as it is of the answer.
