How to Fight Misleading GMO Labelling (in Canada)

Canadian food labelling laws are pretty strict. Unlike in the US, it is not enough for a food label to be true in the general sense. In Canada, there is a specific provision in the Food and Drug Act that “prohibits the labelling, packaging, treating, processing, selling or advertising of any food (at all levels of trade) in a manner that is false, misleading or deceptive to consumers or is likely to create an erroneous message regarding the character, value, quantity, composition, merit or safety of the product.” And while Health Canada and the Canadian Food Inspection Agency may be too pressed for resources to enforce the law every time, when they do the consequences for violators can be serious. Just ask Danone.

Sometimes, mischievous companies try to circumvent the law by using a trademark instead of an outright claim, but in Canada that’s illegal, too. Here’s what the CFIA has to say about that: “[T]he word “fresh” in a product’s brand name might be determined to be misleading to consumers if it implies that food itself is fresh when it is not. Generally, the word “fresh” implies that food is not canned, cured, dehydrated, frozen or otherwise processed or preserved.” For a more detailed and in-depths breakdown of Canadian law on the use of trademarks to circumvent labelling laws, I recommend this article, but in short: if your claim would be illegal under Canadian law, don’t try to make it a trademark, either.

This brings us to the question of GMO labelling in Canada. Thanks to almost two decades of fearmongering by misguided activists and the billion dollar “organic” food industry many consumers have been convinced that genetically engineered crops and foods made from these crops pose a unique danger to the environment and human health. Never mind that there is absolutely no scientific foundation for these beliefs – there’s lots of money to be made from fear, and there are always unscrupulous operators willing to do so.

Many companies have tried to bank on these fears by using “non-GMO” labels, implying their foods are somehow better than those not carrying that label. But, slapping a non-GMO label on your product has been illegal since 2004, when the Canadian General Standards Board adopted the (awkwardly named) national standard for the “voluntary labelling and advertising of foods that are and are not products of genetic engineering.” This standard – which is binding under Canadian law – “applies to the voluntary labelling and advertising of food in order to distinguish whether or not such foods are products of genetic engineering, or contain or do not contain ingredients that are products of genetic engineering, irrespective of whether the food or ingredient contains Deoxyribonucleic Acid (DNA) or protein.” Under this standard, it is illegal to describe pretty much any food as “not genetically modified.” As described in the introduction of the standard,

“It has been recognized that the term genetic modification is sometimes used as a synonym for genetic engineering as defined in this standard. However, to genetically modify a plant, animal, or micro-organism implies making any change to the genetic makeup of the organism by any intentional means whatsoever and is defined in this manner in the Food and Drug Regulations. Because of the broad nature of this definition, many food products would be considered genetically modified, and very few could be considered non-genetically modified. In order to meet the needs of consumers for information about the application of specific techniques of biotechnology, the standard limits itself to claims about the use of genetic engineering in the production of foods and food ingredients.”

Until quite recently, this standard made it legally impossible for all but the most unscrupulous companies to slap a “non-GMO” label on their products. That is, until a group of clever American anti-GMO activists came up with the idea of creating what seemed like a smart solution: they created an organization called the “Non GMO Project,” and developed a “standard” under which companies could use their pretty logo as a “seal for GMO Avoidance.”

Like a plague of wheat rust, this seal is now appearing mostly on the products of smaller brands, but also large companies like Post Foods, who really should know better. Even my otherwise beloved Costco is selling these products – which breaks my heart every time.

But, and this is the critical point, this “logo” is illegal in Canada.

According to the “standard” developed by the Non GMO Project, “GMO, or genetically modified organism, is a plant, animal, microorganism or other organism whose genetic makeup has been modified using recombinant DNA methods (also called gene splicing), gene modification or transgenic technology.” The full “standard” can be found here, and on page 23 elaborates more on this definition.

This definition is what per Canadian law should be referred to as “genetic engineering”, not “genetic modification.” It is therefore illegal to use the term “Non GMO” for products that are not made by means of genetic engineering, but are still genetically modified (which is pretty much every plant that isn’t a wild blueberry or fiddlehead).

But that’s not where it ends. According to the CGSB standard – which, I must repeat, is legally binding in Canada – it is illegal to label a food as “not genetically engineered” if there are no genetically engineered variants for sale in Canada. For example, it is illegal to label a tomato as “not genetically engineered” (never mind “not genetically modified”), since no tomatoes sold in Canada are genetically engineered.

The technical language for this in the standard is here:

B2.5.2 Claims that a food is not a product of genetic engineering, when no similar foods that are products of genetic engineering have been offered for sale, are considered misleading because they create the false impression that the product is unique. In such cases, it is appropriate to use an alternate statement or to include an explanatory statement to avoid misunderstanding (par. 6.1.4 and 6.2.4).


These onions are not a product of genetic engineering, non-genetically engineered chicken, and non-genetically engineered asparagus are unacceptable statements, since they imply that onions, chicken, or asparagus that are products of genetic engineering have been offered for sale.

So, whenever you see a package of quinoa with the “Non GMO Project Verified” label, you are looking at an illegal product – unless it clearly states that there is no GMO quinoa on the market (Quinoa is probably not genetically modified as per Canadian law. I think.) And any wheat or soy product bearing the label is definitely illegally labelled, since there is not a single variant of wheat or soy on the market that isn’t genetically modified as per Canadian law, and there’s definitely no genetically engineered wheat on the market.

The Non GMO Project Verified label is a blatant attempt to circumvent Canadian law by means of a trademark based on a marketing gimmick disguised as a standard. This “standard”, however, was put together by a group of activists with no oversight from any reputable scientific or industry organization, never mind any government agency. It’s a purely private label companies are allowed to use for a fee so that they can better market their products to a misinformed public. The label is designed to imply that products that carry it are better, healthier, and more environmentally friendly than products that do not carry this label. In short, it’s pure consumer fraud.

Companies that use this label in Canada are either ignorant of Canadian law, or believe that a private American label can be used in disregard of Canadian law.

Fortunately, there’s a way to put a stop to this. The Canadian Food Inspection Agency, which is the Canadian government agency responsible for enforcing Canadian food labelling laws, is obligated to respond to consumer complaints about illegally labelled food products. For this purpose, it has set up a complaints mechanism on its website any consumer can use to identify illegal labels.

This is the link:

The form requires quite a bit of information about both the person filing the complaint, as well as the product about which the complaint is filed. In addition, the form requires a specific description of the complaint. I suggest the following wording – though I welcome any suggestions for better wording:

This product carries the “Non GMO Project Verified” logo, implying the food is not genetically modified. This claim is in violation of CAN/CGSB-32.315-2004 “Voluntary labelling and advertising of foods that are and are not products of genetic engineering,” according to which the term “not genetically modified” may not be used as a food label in Canada. The use of a logo violates Canadian labelling law, according to which “the use of trade-marks in labelling and advertising food sold in Canada must comply with applicable federal food legislation, including the Food and Drugs Act (FDA) and Consumer Packaging and Labelling Act (CPLA).”

If enough people file complaints about such products, the CFIA will have little choice but start investigating and take action.

Consumer fraud is wrong. Time to put a stop to it.

50% of Global Electricity from Wind? Not so fast.

One of the most puzzling studies on the viability of providing global electricity from primarily wind and solar is Mark Z. Jacobson‘s and Mark A. Delucchi’s 2011 paper “Providing all global energy with wind, water, and solar power, Part I: Technologies, energy resources, quantities and areas of infrastructure, and materials,” published in Energy Policy. The paper has been cited more than 280 academic papers so far, and tends to crop up all over the place when discussing alternative energies. Let’s look at some of their assumptions. In their introduction they state that they’ll only consider

  • “options … that can be scaled up as part of a global energy system without further major technological developments”
  • “technologies that have low impacts on wildlife, water pollution, and land”
  • “do not have significant waste-disposal or terrorism risks associated with them”

They then go on to argue that wind power meets these criteria best, followed by concentrated solar.

I’m not entirely sure how wind turbines have low impacts on wildlife and land, considering the just under 50,000 wind turbines in the US already kill entire populations of bats and hundreds of thousands of birds – while Jacobson and Delucchi recommend to build at least 540,000 more by 2030. I’m also not going to discuss why their dismissal of nuclear power is wrong – I’ll leave that to others.

I’m going to stick entirely to basic wind power facts. Jacobson and Delucchi that by 2030, total global electricity demand will be about 100,740TWh, requiring approximately 11.5TW installed capacity, approximately five times of current values. So far, so reasonable.

But it’s what follows makes very little sense, and seems completely wrong.

They then suggest that 50% of this demand (50,370TWh) can be met by 3.8 million turbines, with a capacity of 5MW (5.75TW installed capacity) taking up about 1.17% of the global land surface. But to arrive at these numbers they make some very unrealistic assumptions. For example, to generate 50,370TWh with 5.75TW installed wind capacity assumes a capacity factor of 30.26%, that is: they produce on average 30.26% of their nameplate capacity. That is highly optimistic at best, and misses some important points.

It is true that current wind power systems in the US have an annual capacity factor of about 32%. Some wind projects in the UK and Denmark have reached annual capacity factors of close to 50%. But that is not enough. Annual capacity factors don’t tell us anything about how much electricity a turbine will produce at any given time, which may range from 0% to 100%.

What matters more than average capacity factors is the ability for wind to replace conventional power sources at any given time, also known as the replacement factor: how many units of wind capacity needs to be installed to replace one unit of conventional capacity? When wind power provides only a small fraction of the total energy generating capacity – say 1% – the replacement factor does not matter very much. Even if there is no wind, it is no serious challenge to increase power production of other generating stations by 1%. However, as the share of wind increases, the ability of the overall system to absorb these fluctuations becomes diminished, and it becomes necessary to overbuilt wind capacity to ensure it generates sufficient electricity even when there is little wind. As the share of wind generating capacity increases, the replacement factor goes down – to the point that it if wind reaches requires 25 units of installed wind capacity to replace a single unit of conventional capacityregardless of the average capacity factor.

Jacobson and Delucchi’s calculations do not appear to account for the diminishing returns on installed wind capacity and instead appear to assume that the capacity factor is all that matters. Once the replacement factor is taken into consideration, the numbers for how many 5MW turbines will be required to generate 50% of electricity in 2030 are quite different from those calculated by Jacobson and Delucchi: 28,75 Million, not 3.8 Million.

Jacobson and Delucchi further assume that the total land surface required for their 3.8 million wind farm of 5MW turbines would take 1.17% of global land area. I did not see them reference any specific wind turbine, but I will base my calculations on the 526 Hysosung 5MW offshore wind turbines, with a diameter of 139m. (In my calculations, I generally assume a minimum spacing of 6x diameter. The exact numbers depend on complex factors, but using a formula with 6x diameter (approximately 5x diameter between rows, and 7x diameter between turbines) provides a very good minimum space requirement for wind farms when compared to existing projects. ) Using a more realistic 6x turbine diameter spacing, 3.8 million turbines with a diameter of 139m would require a wind farm of at least 2,075,896 square kilometers – equivalent to 1.39% of global land area. Not 1.17%. To reach their number, the spacing is closer to 5.5x diameter. That’s extremely tight spacing – even by current standards.

Still, 1.17% of global land surface is equivalent to 12.2% of Russia, 20.8% of Canada, 105.2% of Mexico, and 379.5% of France, or 10,949% of Lake Ontario.

However, when combined with the more realistic 28.75 million turbines required to generate 50% global energy demand, and using a minimum spacing of 6x diameter, one would have to build a windfarm covering 15,705,792 square kilometer – that is 10.5% of the global land area, or 92% of Russia, 157% of Canada, 2,871% of France, or 82,836% of Lake Ontario.*

How much would it cost to build this many turbines? If we generously assume 1MW of nameplate capacity costs about $1.3M (the lower bound right now), and that ramping up production by at least an order of magnitude per year will not increase prices, building 28.75 million turbines would cost at least $187 trillion – more than 10 times current US GDP. For Jacobson and Delucchi’s calculations to be defensible, they must address the replacement factor issue. I don’t see how they can, though – and I must conclude that their entire thesis is based on a catastrophic conceptual error.




*An earlier version of this article had included a silly mistake – I had accidentally used the total surface of the earth to derive Jacobson and Delucchi’s spacing assumptions. That had two effects: I thought they had made a surprisingly realistic assumption on spacing (about 10x turbine diameter vs my 6x), while also creating a much greater space requirement for the total number of turbines that are required to meet 50% of global demand by 2030. Unfortunately, once I plugged in the correct number for the global land surface it appears their assumptions on turbine spacing are too tight by almost 10% even by current standards – and therefore underestimate land requirement for their 3.8 million turbines by a non-trivial 15.8%. Since new research seems to suggest turbines should be placed apart an even greater distance – possibly up to 8x turbine diameter – space requirements of a realistic wind farm to supply this much power will be even greater. However, I will stick to the 6x diameter standard to avoid accusations of being unfairly biased against wind.

There’s DNA in Your Food!

In the tradition of Penn & Teller’s hilarious send-up of food activists signing a petition to ban water, the otherwise rather serious authors of the monthly Food Demand Survey sometimes try to have a little fun. While the bulk of the survey deals with consumers’ willingness to pay for pork, chicken, or beef, and their weekly food expenditures, it also contains some “ad-hoc” questions, some serious – and some not so much. Consumer responses to these questions range from the interesting to the downright hilarious. In December 2014, for example, a whopping 20.41% of consumers said they would eat a protein bar made from – insect flour. That’s rather impressive – and very sensible of them. The January 2015 edition, however, contained a real gem. At first priming their respondents (victims?) with questions straight from the CSPI playbook: “a tax on sugared soda?” (Opposed, at 60.91%), “mandatory calorie labels on restaurant menus?” (Supported, at 69.11%), and “Mandatory labels on foods produced with genetic engineering?” (Supported, at 82.28%), the authors went straight for the absurd and asked about support for the “mandatory labels for foods containing DNA.” Result? 80.44% support this. Yes, that’s right – 80.44% of consumers appear to support the mandatory labelling of foods containing DNA. And frankly, I think that’s a great idea. Congress should get right to it. As soon as it is done with the “Let me Google that for You Bill” currently before the Senate.

Starbucks in China, or how reading the Atlantic can make you dumber

To say that I’m no expert on China is a grand understatement. To be honest, I have no clue about China at all, at least no more than your average white Canadian middle-class schmuck who thinks that nee-howing the hostess at the local Emerald Palace is the apex of worldliness. I can probably find China on an unmarked world map with fair accuracy, and I know that Beijing is the capital city, but beyond that – sorry.

So, having that cleared up, I will now proceed to call bullshit on a cute little story that appeared in the Atlantic just a few days ago (and two days earlier in the Wall Street Journal), according to which a Starbucks grande latte costs about $27 in Beijing. Once the price is adjusted for national income.

Before I continue, I want to point out that the original WSJ article was quite good. It lists a number of political and economic reasons why coffee in China is so relatively expensive. That was interesting. And informative. I expect as much of WSJ reporting. Had I read only the WSJ article, I wouldn’t have bothered with it any further.

However, the Atlantic article was bad. Really bad. In fact, it was so bad that if you have read it, you are currently a little dumber for it than you were before.

Let’s take this step by step.

According to the Atlantic’s Matt Schiavenza, Chinese per capita income is about $7,200, while a cup of name-brand hot milk with a shot of overly bitter coffee costs $4.80. Since US income per capita is about 5 1/2 times greater, Mr. Schiavenza multiplied the price of joe by 5.5 and – voila: we have $27.

That’s cute. But it’s also wrong.

I have no idea where Mr. Schiavenza has his numbers from. Seriously. No idea. According to the World Bank, Chinese GDP per capita in 2012 was $6,091, not $7,200 – as claimed by Mr. Schiaveza. The funny thing is that the earlier story in the WSJ pegged the average national income at “about” $7,500. I have no idea where that number comes from, either – but it seems obvious Mr. Schiaveza felt uncomfortable with it, and reduced it by $300. I have tried to find the source for either of these numbers. I really tried. I even went to Wikipedia, which lists nominal GDP per capita according to three different sources, but none of which come even close to $7,200 – never mind $7,500. I then went to the Wikipedia page on “per capita income,” which lists a bunch of additional measures, such as GDP (PPP) per capita, GNI (Atlas Method) per captia [???], and GNI (PPP) per capita, but those numbers are totally different again.

If any of my handful of readers could point me to where the WSJ got its numbers from, and which source Mr. Schiavenza used for his article, I would be truly grateful. Because, for now, I’m utterly mystified.

Ok, moving on: according to the World Bank, US GDP per capita in 2012 was $49,965 – a whopping 8.2 times more than China’s middling $6,091. Which means that Starbucks grande lattes in Beijing cost the equivalent of $39.38, not $27. Which means the Chinese must be even crazier than either journal suggested.

Ha, those weird Chinese!

But, wait a minute. China is a really big country. I mean, really big. It has 40 times more people than Canada – and since nobody knows how many people live in Canada, that’s about four times as many as in the US. And it’s also really large, just a smidgen bigger than the US of A – including Alaska and Hawaii.

And just like in Canada – or the US – not everybody in China makes the same money. You think income inequality in the US is bad? Well, it is. The top 10% of Americans make about 16 times more than the bottom 10%. But in China – they make almost 22 times more. And that’s if you believe all the high-rolling Chinese report their income honestly.

The top 10% of China are about 130,000,000 people – that’s more than four times the population of Canada. Try to picture this: four times as many people as live in all of Canada constitute the top 10% of income earners in China.

Or try this one: two years ago, there were more than a million millionaires in China. China has more billionaires than Russia. And only the US has more billionaires than China. Ok, almost four times as many. But, I think you get my point: there are a huge number of really, really rich people in China.

Even more interestingly, there are a number of cities in China where people make good money – even by US standards – on average. Measured by Purchasing Power Parity (look it up), average income in 2011 in Beijing was 19,854 – about the same as in Pensacola, Florida. And there are at least four Starbucks in Pensacola – for about 52,000 people. Beijing has maybe a dozen – for 20 MILLION.

Average income (PPP) in Guangzhou is about $23,700, about the same as the Fort Collins–Loveland, Colorado Metropolitan Statistical Area (damn you, United States Census). Fort Collins has about 147,000 people and just about a dozen Starbucks. Guangzhou has about 10 MILLION people and about a dozen Starbucks.

Start seeing a pattern here? If not, let me help you out: there are Chinese cities that have more people than most US states, but have fewer Starbucks in absolute numbers than almost any fourth-rate US town – there are more Starbucks in Detroit than in Beijing.

In China, there are about 850 Starbucks cafes. In the US? 13,279. 16 times as many. But it has less than a quarter of China’s population. So, while in the US, there is one Starbucks cafe for 23,453 people, in China there is one Starbucks cafe for 1.56 million people. That means that, per capita, the US has 68 times as many Starbucks cafes as China. Even if you adjust this number for income, that is: divide the excess number of Starbucks cafes in the US by the income ratio (8.2), the US still has 8.32 times more Starbucks than China per capita of people who make about the same amount of money.

Wait… this is interesting…

Starbucks coffee in China costs about 8 times more than in the US, relative to average income. However, there are also only about 1/8 as many Starbucks in China for every consumer with the same average income as an American. This means that if in the US there were as many Starbucks as in China, relative to population and income, there would be only about 1,600 Starbucks cafes, not 13,000. Or put differently, Starbucks would have to have at least 7,000, not 850, outlets in China before reaching the same level of outlets relative to the population that can afford going there. And for these people, the cost of Starbucks coffee relative to their income is the same as for Americans.

See, all it took to figure out that the entire argument so far was bullshit is a few minutes on Google, and a pinch of logic.

Which Mr. Schiavenza clearly lacks, or else he wouldn’t have written this howler:

With the rise of e-commerce—and more frequent foreign travel—Chinese consumers have begun to feel that they’re paying too much for simple pleasures like a cup of coffee.

Never mind the fact that Mr. Schiavenza provides absolutely no evidence for this change in consumer opinion – other than his expat friend. What I would like to know is this: what on earth does e-commerce have to do with coffee? When is the last time you ordered your grande no-foam soy latte through Amazon? And how likely is it that your average globetrotting, coffee-sipping nouveau riche Chinese will spend time exploring cheaper coffee alternatives while in New York, London, Paris, or Frankfurt?

This is just a stupid argument.

But, there’s more.

Here’s where it gets tricky, and here is where the Atlantic article really went out of its way to make you a little bit dumber.

I’ll walk you through it.

Schiavenza writes:

Most cities in the country have coffee shops that provide a roughly similar cup of coffee—and similarly comfortable atmosphere—at much lower prices. How does Starbucks make it work?

I doubt this. In the original WSJ article there was a chart – also included in the Atlantic – that broke down the various cost factors for Starbucks’ coffee:

Notice how almost all these costs are outside the control of Starbucks? With the exception of the profit margin – 18% – I don’t see much room for significant cost reductions if you wanted to run a coffee store with similar atmosphere and quality coffee. Where would you cut, dear reader? The rent and store operating expenses? There goes the atmosphere. The raw materials? There goes the quality.

I really would love to see those places in Beijing and Shanghai with “roughly similar cup of coffee—and similarly comfortable atmosphere—at much lower prices.” Having lived in, and visited, a number of major cities in North America and Europe, I have found that if you want a really good cup of coffee in a nice atmosphere, you pay about the same as you do at Starbucks. You can get cheaper, but you’ll compromise either on the atmosphere or the quality of the coffee. I have had excellent coffee at highway rest stations in Germany, though you really can’t compare that to a well-run Starbucks in terms of atmosphere.

But what does our Atlantic writer provide as the real reason?

One major issue is culture.

Ah… yes… That mysterious Chinese culture. Of course. Let’s see how that goes:

Since the Chinese economy opened up to import products in the late 1970s, these goods acquired a certain cache with image-conscious consumers. “Traditionally foreign products were regarded as better-made, higher-status, and simply nicer,”

I may be going out on a limb here, but I don’t believe that back in the late 1970s the idea of Western products being of better quality than Chinese products was much of a stretch. Considering the Chinese had just gone through decades of social upheaval, wars, and communist mismanagement – it would have been shocking if Western products had not been of better quality. That’s not a weird Chinese culture thing, that’s an economic development thing. Countries with lower levels of economic development generally produce products of lower quality. That’s almost a tautology.

Why am I belaboring this point? Because I’m ticked off by the implicit presentation of the Chinese as stupid dupes. Wanting better products is not some weird Chinese cultural thing. It’s a universal human thing. You work hard for your money. You want to spend it on things that give you as much utility and pleasure as possible. Europeans are like that. Americans are like that. Well, except for those who ‘buy American’ out of principle. That’s just dumb.

In any case, let’s move on:

Fei Wang, a Washington, DC-based consultant who grew up in Wuhan, told me. “A person’s social standing was defined by the objects they own.”

Oh – fascinating. Those weird Chinese… defining their social standing by the objects they own. Amazing. Tell us more about those exotic strangers.

Far from acting as a deterrent, high prices actually enticed customers who wanted to show off their new affluence; put another way, purchasing a good like a cup of coffee at a premium was a good way to obtain “face” in business or personal relationships.

Ah… that mysterious Chinese concept of “face”. I’m kind of disappointed the scare quotes around the word weren’t amplified by including 面子 in brackets. Because in the US or Canada, nobody would even think about impressing a business partner or anyone else by inviting them to a fancy restaurant or coffee place. No, here, in our rational Western society, we don’t care about such superficiality at all.

And Starbucks had the good fortune of entering the country at a time when coffee drinking became fashionable among hip, young Chinese consumers.

What a coincidence. How fortunate for Starbucks they just happened to enter  the Chinese market when the Chinese started to take a fancy to coffee. What a lucky, lucky company.

Please excuse me while I smack my head on my desk.

There. Better.

Eventually, though, Chinese customers may decide that a latte is just a latte—and the no-name place down the street is more than good enough.

How much Electricity does Solar Power generate?

I’ve spent quite some time and effort on calculating the space requirements of wind power installations during my time at the Canadian Nuclear Association. The fruits of my labor can be found on pages 13 and 24 of the Canadian Nuclear Factbook (the numbers are actually not quite correct, they greatly favor wind by assuming a pretty unrealistic utilization rate of 25%).

However, calculating wind is easy. Turbine manufacturers are more than happy to post the capacity of their machines online, and there’s also a lot of data available on the productivity of various wind farms, both in the EU and North America. The rest is simply geometry.

Solar power installations are trickier. There are far more variables in terms of the technologies used and the local geography. Also, solar power manufacturers seem far more coy about the generating capacity of their products, at least as far as their websites are concerned. I think the reason is that the technology simply isn’t that straightforward.

However, there are the occasional nuggets of good data that can be used to extrapolate some of the data I am interested in. For example, in this recent post by the US DOE, we find the following data:

Mesquite Solar 1 taps into 300 days of sunshine each year to generate 150 MW of clean electricity — enough to power about 30,000 homes.

Let’s break this down:

According to SW Energy, annual electricity consumption for per household is just above 11,000kwh.

If this facility can provide power for 30,000 households, it must generate at least 330,000,000kw/h annually.

Since the anticipated output of Mesquite Solar 1 is to be  about 330,000,000 kw/h, this means that even in an ideal location like the Arizona desert, a solar power facility can be expected to operate with at about 25% utilization.
