Wind turbines are neither clean nor green and they provide zero global energy

From The Spectator

We urgently need to stop the ecological posturing and invest in gas and nuclear

Matt Ridley

The Global Wind Energy Council recently released its latest report, excitedly boasting that ‘the proliferation of wind energy into the global power market continues at a furious pace, after it was revealed that more than 54 gigawatts of clean renewable wind power was installed across the global market last year’.

You may have got the impression from announcements like that, and from the obligatory pictures of wind turbines in any BBC story or airport advert about energy, that wind power is making a big contribution to world energy today. You would be wrong. Its contribution is still, after decades — nay centuries — of development, trivial to the point of irrelevance.

Here’s a quiz; no conferring. To the nearest whole number, what percentage of the world’s energy consumption was supplied by wind power in 2014, the last year for which there are reliable figures? Was it 20 per cent, 10 per cent or 5 per cent? None of the above: it was 0 per cent. That is to say, to the nearest whole number, there is still no wind power on Earth.

Matt Ridley and climate change campaigner Leo Murray debate the future of wind power:

Even put together, wind and photovoltaic solar are supplying less than 1 per cent of global energy demand. From the International Energy Agency’s 2016 Key Renewables Trends, we can see that wind provided 0.46 per cent of global energy consumption in 2014, and solar and tide combined provided 0.35 per cent. Remember this is total energy, not just electricity, which is less than a fifth of all final energy, the rest being the solid, gaseous, and liquid fuels that do the heavy lifting for heat, transport and industry.

Such numbers are not hard to find, but they don’t figure prominently in reports on energy derived from the unreliables lobby (solar and wind). Their trick is to hide behind the statement that close to 14 per cent of the world’s energy is renewable, with the implication that this is wind and solar. In fact the vast majority — three quarters — is biomass (mainly wood), and a very large part of that is ‘traditional biomass’; sticks and logs and dung burned by the poor in their homes to cook with. Those people need that energy, but they pay a big price in health problems caused by smoke inhalation.

Even in rich countries playing with subsidised wind and solar, a huge slug of their renewable energy comes from wood and hydro, the reliable renewables. Meanwhile, world energy demand has been growing at about 2 per cent a year for nearly 40 years. Between 2013 and 2014, again using International Energy Agency data, it grew by just under 2,000 terawatt-hours.

If wind turbines were to supply all of that growth but no more, how many would need to be built each year? The answer is nearly 350,000, since a two-megawatt turbine can produce about 0.005 terawatt-hours per annum. That’s one-and-a-half times as many as have been built in the world since governments started pouring consumer funds into this so-called industry in the early 2000s.

At a density of, very roughly, 50 acres per megawatt, typical for wind farms, that many turbines would require a land area greater than the British Isles, including Ireland. Every year. If we kept this up for 50 years, we would have covered every square mile of a land area the size of Russia with wind farms. Remember, this would be just to fulfil the new demand for energy, not to displace the vast existing supply of energy from fossil fuels, which currently supply 80 per cent of global energy needs.

Do not take refuge in the idea that wind turbines could become more efficient. There is a limit to how much energy you can extract from a moving fluid, the Betz limit, and wind turbines are already close to it. Their effectiveness (the load factor, to use the engineering term) is determined by the wind that is available, and that varies at its own sweet will from second to second, day to day, year to year.

As machines, wind turbines are pretty good already; the problem is the wind resource itself, and we cannot change that. It’s a fluctuating stream of low–density energy. Mankind stopped using it for mission-critical transport and mechanical power long ago, for sound reasons. It’s just not very good.

As for resource consumption and environmental impacts, the direct effects of wind turbines — killing birds and bats, sinking concrete foundations deep into wild lands — is bad enough. But out of sight and out of mind is the dirty pollution generated in Inner Mongolia by the mining of rare-earth metals for the magnets in the turbines. This generates toxic and radioactive waste on an epic scale, which is why the phrase ‘clean energy’ is such a sick joke and ministers should be ashamed every time it passes their lips.

It gets worse. Wind turbines, apart from the fibreglass blades, are made mostly of steel, with concrete bases. They need about 200 times as much material per unit of capacity as a modern combined cycle gas turbine. Steel is made with coal, not just to provide the heat for smelting ore, but to supply the carbon in the alloy. Cement is also often made using coal. The machinery of ‘clean’ renewables is the output of the fossil fuel economy, and largely the coal economy.

Ireland is NOT one of the “British Isles” As it’s name would suggest, it’s Irish.

The official title is: The United Kingdom of the British Isles and Northern Ireland. So without taking sides on the issues of a divided Ireland, it is decidedly NOT part of the British Isles even according to Her Majesty’s government.

That the very British toff 5th Viscount Sir Matthew White Ridley pretends not to know that is disrespectful and insulting, not an accident.

Oh dear! Geography is clearly not your strong point. There was no disrespect. The island of Ireland is part of the British Isles.

Here is a brief tutorial from the (British!) Ordnance Survey.

The difference between UK, Great Britain and the British Isles

Ordnance Survey team
One of the most common mistakes people make when talking about geography in this country is to confuse the UK with Great Britain or the British Isles – a cardinal sin in the eyes of any true geographer!

So let’s clear this up once and for all…

The United Kingdom

The United Kingdom of Great Britain and Northern Ireland (to give its full name) refers to the political union between England, Wales, Scotland and Northern Ireland. The UK is a sovereign state, but the nations that make it up are also countries in their own right.

From 1801 to 1922 the UK also included all of Ireland.

The Channel Islands and Isle of Man are not part of the UK, but are Crown Dependencies.

Great Britain

Great Britain is the official collective name of of England, Scotland and Wales and their associated islands. It does not include Northern Ireland and therefore should never be used interchangeably with ‘UK’ – something you see all too often.

Here at Ordnance Survey, we’re responsible for mapping Great Britain, which is why we don’t make maps of Northern Ireland.

British Isles

This is purely a geographical term – it refers to the islands of Great Britain and Ireland – including the Republic of Ireland – and the 5000 or so smaller islands scattered around our coasts. Remember this only refers to geography, not nationality, and while the Republic of Ireland is part of the British Isles, its people are not British – a very important distinction.

I hope that’s explained the very different meanings between UK, Great Britain and British Isles and why it’s important to use the right name at the right time. Geography really does matter!

We could go on to talk about nationalities but maybe we’ll save that for another day…

Try again, it is the United Kingdom of Great Britain and Northern Ireland.

Whereas the British Isles is a group of islands in the Atlantic Ocean off the coast of Continental Europe. It includes Ireland, Great Britain, the Isle of Man, Shetland, Orkney, and thousands of smaller islands. It is a geographical term, not a political one.

Reply to  Greg
January 10, 2019 5:45 am

The British Isles is a term coined by the mediterranean civilisations, first appearing in writing in about 500BC as Pritaigne, later changed by the Romans (possibley in error) to Britaigne. It encompasses all of these islands off the north west coast of mainland Europe.

The “official title” as you put it is The United Kingdom of Great Britain and Northern Ireland. Great Britain being the largest Island of what we now call the British Isles.

There is a difference between global electricity demand and global energy demand.

so far the biggest advances in renewables are in electricity, not heating or transport.

It is therefore convenient for those who want to run down renewables to focus on all energy rather than on electricity.

If you look at renewable electricity in developed nations and in India and China it is clear renewables and wind in particular are making a significant and increasing contribution to the electricity supply and they are both clean and green

Did you even read the article? The author wasn’t trying to hide anything or continue to deceive as wind-power advocates must do.

“Remember this is total energy, not just electricity, which is less than a fifth of all final energy,” with the other four fifths being used for “heat, transport and industry”.

So with a wave of the hand, you want to completely dismiss 80% of the world’s energy needs because wind isn’t of any value in furthering the propaganda. It isn’t important that people can cook or heat their homes and factories, not at all relevant that people and things need to be moved around; that crops need to be grown, processed and shipped; that products need to be manufactured – none of all this matters, just that there is enough wind at the moment to power up your Apple products.

You probably also missed that the definition of “renewables” that includes burning of wood, peat and feces. Much easier to conflate and deliberately deceive others into thinking that wind is even a significant slice of the “renewable” pie by equating all renewable energy as either PV or wind.

It seems that you missed the entire point of the article.

And a very important point. I use a heat pump to heat my home. The economic crossover point is at 25 oF with todays gas prices. That means more than 75% of the time it is cheaper to heat my home with my HP than the high efficiency gas furnace. The only way every one in the USA can heat with electricity an not have CO2 emissions is when the majority of the electricity is generated from nuclear power.
Same applies to electric cars and other transportation.

And equally convenient for those who want to push the case for renewables to ignore the fact that the plan is for renewables to supply all the world’s energy needs, primarily by eliminating as far as possible those energy demands that cannot be met by wind or solar. Neither wind nor solar are “clean” (whatever that means) nor “green” (you need to painfully selective in your thinking to come anywhere close to believing that).

The fuel may be “clean” but its intermittency makes it totally unsuitable as a provider of reliable energy for a civilised society. Perhaps griff would care to explain to us which aspects of civilisation he, personally, would be happy to sacrifice in order for this utopian dream to become a reality.

Oh that much is self-evident. All electricity will be supplied by wind and solar, that electricity will be used for the benefit of the ruling green priest class, and the restcpf us can burn renewable wood (as long as it holds out) or dung to cook the birds and bats killed by the windmills and thermal solar plants. This will provide a protein supplement to the subsistence farming we engage in for survival in the shadow of all those windmills. Once the raptor are gone, the rodent population will boom and we may be allowed to hunt those to add to our diet.

e.g. Manufacturing, refining, mining, smelting, concrete production, fertilizer production, plastics production, transport by any vehicle, flight by any vehicle, building construction, etc. etc,; even including constructing, installing and maintaining wind turbines.

Instead, everyone is supposed to wear blinders so they can only view the pathetic wind and solar farms supplying trivial amounts of poor quality electricity sporadically.
All while consuming huge quantities of raw material, vast swaths of land, and unable to provide reasonable length of service.

If not, then it is justifiable to include all forms of energy when calculating what fraction is being produced by renewables.

In other words, if you want to power everything using “renewable” energy, than it is correct to use all energy when calculating how much more energy renewables are going to have to create.

Wind? Probably not

Solar? Yes, although it would require paving much of the planet’s mid-latitude deserts with solar panels, and probably is NOT a good idea using current storage technology. Solar hot water heating incidentally is currently cost effective for a large percentage of the people on the planet and is — along with better insulated housing — something that is both green and worth supporting.

BTW, the percentage of world energy usage provided by wind in the 18th and early 19th centuries was much higher than today. It fell out of favor because it simply didn’t work very well. e.g. It took the Mayflower NINE WEEKS to make the relatively short trip from England to Cape Cod Bay. And that wasn’t all that unusual.

Howevere, there’s no doubt that the mainstream media and governments along with so-called “green energy” promoters have done a great job in conning the general public. One of these days, people will finally wake up and put a stop to this scam.

BTW, I couldn’t get the link to the original article to work. Thanks!

It’s on Matt’s Blog.

It also includes the alteration that hasn’t been included in this report which I presume has been cut and pasted from the original Spectator article of some time ago.

The real number is half of Russia would be covered in wind turbines, not the whole of Russia.

Not that it makes much difference because it’s only dealing with the 2% annual growth, ignoring the existing energy mix which would still be churning out many tons of the non-pollutant CO2.

Griff, of course, jumps in with both feet waving his hands about wonderful renewables and misses the point of the article entirely, that merely keeping up with 2% growth would soon swamp the world in wind turbines and we would still need reliable energy from fossil or nuclear.

The other presentation I enjoy is from a committed green, the late Sir David MacKay, who did a TED talk on the futility of renewables.

It’s fun rubbing green faces in both Matt and David’s practical outlook of renewables.

If a wind turbine uses 200 times the materiel per unit capacity, how long does it have to operate before total CO2 emissions from construction and operation are below, say, a CCGT gas plant of the same output? How does that square with the recent article pointing out that Wind Turbine life is actually only about half the original 25 year expectation?

Reply to  Russell Robles-Thome

As an installer of Gas Turbine combined cycle units for 28 years I can tell you some facts about their output. Once they are commissioned the average for the reliability and output is 98% for a years worth of run time. I will concede 2% of the total output for regular maintenance and some upsets due to line conditions or unwanted shutdowns. That is running at the total output of the name plate rating regardless of the size of the unit. The newer Combined cycle units are low emission units that provide reliable power at 1/10 of the emissions that a unit from 1980’s would produce. The total payback on the units footprint depends on the rate given for the power sold but the average I have worked out is 7 years to zero out the emissions required to manufacture. Now a British study looked at the total output from all of the wind turbines installed in Britain over seven years and found that in that time the highest output from ANY wind turbine on any given day never went over 30% of name plate. So if the green crowd is spouting off about wind mills for energy then if they can not get them over 30% of name plate then the whole argument to install these bird choppers is a very unicorn like fallacy for reliable energy.

Find the original non subscription article here:

As a coal miner himself, its odd he doesn’t seem to know how steel is made.
Yes, you make iron, take all the carbon out of it then put just a little back in. And other stuff like vanadium, Chromium, Manganese, Obtainium whatever whatever..
(This is where Chinese steel recyclers go so badly wrong and thus produce Junk Steel – they don’t have any Obtainium. Junk is very apt doncha think?)

But you need the chemistry of carbon reducing iron oxide to iron primarily.
That’s where the coal goes, into the blast furnaces.
Iron Oxide + Carbon > Carbon Oxide + Iron

Adding limestone helps somehow but mainly in producing truly epic soil/dirt conditioner and plant-food in the shape of Basic Slag

How are the fusion reactors gonna work that I wonder?

350.000 wind turbines are needed, each 2 MW. Or 29.200 if each is 12 MW. Danish company Vestas has already produced more than 60.000 windmills! In Denmark windmills produce more than 43% of electricity!

In Denmark, 39% of the wind power in total electricity consumed in 2014 was responsible for only 5% of total energy produced. Notice that the units are different: consumption vs production.

How precise do you want to be? Energy produced as energy produced in an engine? In that case the efficiency is about 30%. Denmark produced 200 TWh (mainly oil and gas and wind power) in 2014, 13 TWh of this was from wind turbines. From oil and gas they got 187 TWh or net 56.1 TWh. The percentage of wind energy is then 18.8 % (13/69.1).

January 10, 2019 5:56 am

The public overestimates by a large degree the amount of renewable energy they consume, according to a recent Ipsos poll. Of course, they have been misled by all the hype in the media. But in addition, sources like the World Bank provide inflated statistics for wind and solar power production. Canada and the Netherlands are two examples showing the hypocrisy.

Overheard, 100 years ago: “We must break from this morbid fascination with coal long enough to modernize our society, and usher in a glorious future of clean energy supplied by beauteous, bountiful, endless oil and its many byproducts! 300 years hence our great civilization will still be purring along on this marvel. All we need do is make the oil derrick safe enough to reside in your town, and that means raising stacks over a hundred feet into the sky to carry that useless, dangerously explosive gas that accompanies the oil up into flares that shall burn day and night.”

Overheard, 50 years ago: “Well who could have possibly foreseen that? We’ve closed down almost all the wells now and capped them off so that useless, dangerously explosive gas does not escape. So now we must break with this morbid fascination with coal and domestic oil to consider the exciting prospect of meddling in the affairs of Middle Eastern governments to ensure a bountiful, endless supply of petroleum arriving on ocean tankers. Surely this prosperity and mutual cooperation will endure for 300 years! Long live the Shah of Iran!”

Overheard:“No nukes! No nukes!”

Overheard, 25 years ago: “Well shucks, who could possibly have known how much trouble the Middle East would become. It’s time to break with this morbid fascination with coal and Middle East oil long enough to modernize our society, and that means retreating into dreamland and proposing marvels of technology that will change everything. The 1990s will go down in history as the decade when fusion energy became closer than ever! Remember, fusion is not fission so it’s okay to talk about it. It’s been around the corner for a while now, that means it will be better than ever! Fusion ships, fusion plants, fusion cars, fusion pacemakers. Every other science story is about fusion, it’s that close! As soon as fusion pops into existence tomorrow it will become our kind’s energy miracle for the next 300 years! And the next.”

Overheard:“No nukes! No nukes!”

Overheard, 15 years ago: “Well it looks like fusion is still around the corner. Why not dispense with this morbid fascination with coal and fusion and put all our effort into solar and wind? Let’s manufacture in other countries countless delicate machines from toxic components and place them out into the elements where they will underperform and wear out quickly. Let us deceive the public and ourselves by failing to mention that all these things together, should we give over completely to them, would support a comfortable utopian modern civilization if we get rid of 95% percent of the people (through Population Control), with the remaining few descending into a Medieval lifestyle in the ruins as the regional grids finally shut down. By scrounging all available parts left over from the Golden Age, the Temple of the Sun and the Temple of the Wind might maintain a ceremonial electric light that will still be burning in 300 years…”

Overheard:“No nukes! No nukes!”

Overheard, 10 years ago: “Hey… remember that useless and dangerous gas byproduct? April fool! We’ve been using it all along despite that CO2 thing. Well it’s time to finally do away with coal and the nice gas will help us to hold on to that solar and wind dream a little longer. We can even use it to help eliminate those 95% of people who are still alive, another unsolved problem. Let’s uncap those wells, dig deep and extract even more of the gas, and crisscross our continent with explody pipelines until all modern civilization is hanging by a tiny thread! Let’s prove to the world that were are smart by changing over to use the gas completely, even spending more energy to compress it and sending giant explody-ships to sell it overseas! Let’s calculate… after more than 80 years of flaring off a terrifying amount of it, fracturing some rock to get a little more, using it almost exclusively for powering the grid, selling out what future we may have by mass exporting it overseas, accounting for leakage in the whole system which now has trillions of parts where it once comprised millions… that leaves us… [deletes result] 300 years! Yes — 300 wonderful years of gassy prosperity while fusion comes around the corner, we eliminate 95% or people (through Population Control) and do some other things, like mopping up the Middle East to obtain a little -surplus-…”

Overheard, 8 years ago: “I have a friend who’s trying to start a rare earth mine in Missouri. ‘Jim, how much thorium do you think you’ll be digging up a year?’ And he goes, “I think about 5,000 tons.” 5,000 tons of thorium would supply the planet… with all of its energy for a year. And he goes ‘And there’s like a zillion other places on earth that are just like my mine. It’s a nice mine, but it’s not unique, it’s not like this is the one place on earth where this is found.’ Every time mankind has been able to access a new source of energy, it has led to profound societal implications. Human beings had slaves for thousands and thousands of years. When we learned how to make carbon our slave, instead of other human beings, we started to learn how to be civilized people. Thorium has a million times the energy density of a carbon-hydrogen bond. What could that mean for human civilization? Because we’re not going to run out of this stuff. We will never run out. It is simply too common.”

Overheard:“No nukes! No nukes!”

Perhaps he read my letter.

Overheard, 2 years ago: [President Trump] “We will begin to revive and expand our nuclear energy sector — which I’m so happy about — which produces clean, renewable and emissions-free energy. A complete review of U.S. nuclear energy policy will help us find new ways to revitalize this crucial energy resource. […] the Department of the Treasury will address barriers to the financing of highly efficient, overseas coal energy plants. Ukraine already tells us they need millions and millions of metric tons right now. There are many other places that need it, too. And we want to sell it to them, and to everyone else all over the globe who need it…”

Overheard:“No nukes! No nukes!”

Too little, too late. Amidst the infantile hype about solar and wind and its insidiously deceptive crypto-advocation of natural gas as THE primary source for grid power generation… and the fusion delayers — no, not the scientists working on the problem, but the every day investors and people putting stock in an ridiculous and unaffordable dreams… they have all been useful idiots.

But in the end, might the least useful idiots of all have been within the industries who have been generating nuclear power from fission over the decades without much fuss.

Clearly more fuss was called for.

Nuclear Energy professionals are excruciatingly polite you see, tragically polite. It is an unfortunate side effect of their safety culture and utopian mindset. They believed that simple performance and demonstrated results would make their case for them, even amidst an ignorant public outcry. They believed nuclear energy would be embraced by neo-hippies who loathe CO2 as nuclear is an emissions-free resource that is guaranteed to succeed. It is maybe the first one that COULD last those ‘300 years’. They were fools.

So they went about their business, and neglected to do the one thing that might have changed the course of history… getting behind the pursuit of Alvin Weinberg’s vision of molten salt reactors and active processing that reduces necessary waste storage to a small volume and brief 300 year span, from a cheap and limitless fuel source.

Nuclear plant operators watched as the percentage of US nuclear feeding the grid rose (much too slowly) to around 20% even as it had reached as much as 70% in another countries, then they watched started dropping again. They have witnessed whole decades without new US construction, or even useful research into molten salts. They have been ‘playing nice’ with everyone, not stirring up much of a fuss. Years ago they became excited about the AP-1000. How many are there operating in the US, today?

The problem is, it’s actually a war and not some public relations challenge. And the modern lifestyle and abundant energy hangs in the balance. When ignorant and unworkable ideas become commonplace, it’s time to lose the politeness and call out the idiocy and engineering-stupids. Raise a fuss.

Overheard:“No nukes! No nukes!”

Statoil and Masdar aim to reduce the costs of energy from the Hywind floating wind farm to EUR 40-60 (USD 50-75) per MWh by 2030.

Don’t get too excited, as an engineer I can tell you that cost is only the difference between keeping it running, or walking away from it when you still have to pay off the R&D and the construction loan. There is nothing in the article about how much government money they sucked up to get it built, nor how much to keep it operating.

@Ketill Jacobsen that’s all we’re asking, if wind is such a great idea, kill the subsidies and mandates, cancel the feed-in tariffs, if they’re the best thing since slice bread they don’t need ’em!!! So far, no wind project has been able to get off the ground without government putting its thumb on the scale somehow. Thus our instant skepticism.

Hywind Scotland had a capacity factor of 65% in its first three months (November 2017 to January 2018). I have not been able to find newer data of production. One of the largest wind mill manufactures (maybe GE) is saying that they expect to obtain a capacity factor of 63% with their 12 MW floating wind turbine.

The EU countries have an electricity production of ca 2900 TWh per year. If the North Sea was built out with a wind turbine farm within a square with sides 950 km long, this amount of electricity can be produced. There is enough area to be used in the North Sea!

Equinor (who built Hywind Scotland) expects a price of € 40 to 60 per MWh within 2030. This price is about the same as the market price at Nord Pool. No subsidies will be required in the near future (onshore windmill electricity is already the cheapest energy)!

I’m supposed to be simultaneously concerned that there is too many people, and we are going to run out of space to grow food, climate change will make it worse via sea level rise, drought etc, we need to plant more windmills and solar cells which take up an enormous amount of space per energy unit?

Ian Macdonald
January 10, 2019 9:16 am

Another way to look at this is that if we want to go ‘100% renewable’ using wind and solar, then taking the best case estimate of 2% of world energy replaced so far in 10 years, that would take 500 years at current installation rates. Current spend is about $350 billion a year.

So, if we wanted to go 100% renewable in 20 years (which some climate alarmists say is necessary) then we would have to up the expenditure by a factor of 25, to nearly nine trillion a year.

The overall cost would be in the region of $175 trillion. For comparison purposes, the Apollo project’s cost was about $270 billion in modern money. So, going 100% renewable would cost as much as 648 Apollo projects. Not allowing for economies of scale and assuming six missions with a 3-man crew per project, that would be just under 12,000 astronauts making a trip to the Moon and back.

Even this ignores the need for energy storage to make wind energy practical as baseload, also the R&D for a moon program only needs to be done once and then you just spend the rest on building rockets at much lower cost. So the actual cost comparison would be worse than this.

Basically, we could put a sizeable colony on the Moon for the same money. That’s how crazy the cost is.

The capacity-weighted average installed project cost within our 2017 sample stood at $1,610/kW. Using that number then using the number of 2 MW turbines turbines needed just to keep up with projected expansion [see article] “The answer is nearly 350,000, since a two-megawatt turbine can produce about 0.005 terawatt-hours per annum.” Then, 350,000 times $3Million/ installation = $1,050,000 Million. About 20% of that $1Trillion would be for the USA, about $200Billion a year, 70,000 Wind turbines a year. Then there is the transmission line and substation construction, Backup generators, and New NG power plants.
Don’t forget, these Wind Turbines will be sucking off about 8 -10% of nameplate output for maintaining equipment operation within the WT. That means that the proliferation of wind turbines alone will increase the load on the grid. For example, if 50% of the power used in the USA was generated from wind turbines, then 4 – 5 % of that power is going back into the idle wind turbines just so they can operate.
Get ready for a whopping electric bill and much higher federal taxes to pay the subsidies.

Matt Ridley’s article is good. But he misses another problem with wind turbines.

The steel used on them needs to be high quality tensile steel… And this also leads to a huge amount of Caron Monoxide being generated during it’s production..I recently heard from a former worker that the Wyalla steel plant here in South Australia when making this steel, generated 1500 ppm of CO wheres the health standard requires just 10 ppm.
