Sports which can be cancelled because of windy weather

Yachting:

While offshore and trans-oceanic racers clearly have no choice but to face the conditions at sea, high winds can also be associated with large waves on inshore courses. Since inshore craft are often smaller than their long-range cousins, races may be delayed or abandoned completely should the race organisers feel that conditions could pose a risk to the safety of the crews or officials.

Aerobatics:

The Red Bull Air Race™ pilots are all very experienced in their field. However, the maneuverability of their aircraft depends on the use of a light airframe, and this can easily be affected by adverse wind conditions. The Red Bull Air Race™ tour around the world is timed to try to avoid well-known local seasonal meteorological “hotspots”. However, if the safety of pilots or spectators is ever called into question, the race will be halted, postponed or completely abandoned.

Jenga:

When played outside, excessive wind can result in the tower being unstable and premature tumbling may occur. If this happens, Rule 8.6(a) allows for the event to either be postponed or moved to a suitable indoor location, provided all competitors are in agreement.

Archery:

Generally only an issue in very high winds, especially those from lateral or semi-lateral directions, driftage of arrows between bow and target could result in potential injury to those in the vicinity. In these instances, competition is suspended until conditions improve. A 4 hour suspension is allowed for by the World Archery Federation, provided that failing light does not then become an additional hazard because of the delay.

Lawn Bowls:

A “howling northwester” (also known as a “stiff breeze”) is usually the only category of wind which can result in cancellation of a game of lawn bowls. Should these be the prevailing conditions, an announcement should be made not earlier than 1 hour and 3 minutes before play is due to commence (when a game has been arranged for 6 weeks or more). While the safety of competitors is unlikely to be compromised by a bit of a blow, the game “is meant to be fun” and clearly, attempting to roll some heavy balls in a mildly gusty Force 5 while nursing a massive hangover falls outside that descriptor.
Competitors should note that there is no internal appeals system within the informal lawn bowls organisation, and any photos of administrators passed out drunk at a party a few hours before the official start time which were shared on social media platforms should be overlooked.
It was entirely the “howling northwester” that was to blame.

Badminton (Outdoor):

You’re taking the piss, right? Completely unmanageable.

How was your Sunday morning?

Change of season

We’ve dealt with the folly of “Spring Day” in South Africa before. The vernal equinox in the Southern Hemisphere is the 23rd September, and not a moment (or 22 days) before.

But despite the fact that it’s definitely not Spring, it is just around the corner. The mornings are getting lighter, the evenings too, and stuff in the garden is beginning to bud and flower.

And so, also coming soon is the biannual Cape Town whinge switch. That moment of the year when the complaining about the cold changes to moaning about the wind. And thus, I was reminded of this piece from last year, which is amongst the most overly dramatic things I’ve ever read about the infamous “Cape Doctor”. Or anything else, actually.

A pal was visiting from New York when Cape Town was at Peak Wind, and one day she came into my flat from out of The Wind, looking all startled and like she had just been in a war, and said “I don’t know how you live like this.” Me neither, friend. I wake up sometimes at night and think, “This cannot go on.” I wake up and think “This is too loud for nature.”

“Peak Wind” is not a phrase any local person would use. This is the language of someone trying to make a hurricane out of a simple evening gale.
“Like she had just been in a war”. Wow. Was she dead or missing a limb or something?

No.

Yes, I’ve lived in Vredehoek. Yes, I’ve witnessed garden furniture flying off the deck, but no, I’ve never thought:

 I bet you the wind kills people every day.

Or:

The wind robs us of our life force, so that all we can do is be angry and text each other about how much we hate it. The wind, the wind, the wind.

Honestly, love. Get a grip.

It’s been a chilly couple of weeks, and it’s been discussed widely on social media. That’s winter in Cape Town. A succession of cold fronts that (usually, anyway) bring wind and rain. Now, as we approach spring, we’re allowed to complain about the wind. It is sometimes annoying.

But should you be tempted to:

…send each other texts that say things like “This wind is destroying my quality of life” and “I can’t handle the wind” and “Let me tell you the wind.”

(That last one doesn’t even make sense.)

Or if you ask questions about the wind like:

Why it makes us all want to just pitch ourselves off the roof?

or:

Why it makes us lose our entire personalities?

Then you’re overstating its effects rather too much.

I don’t know if the author is still in Cape Town, but having gone through another summer complete with the South Easter blowing, I’m guessing that she’s either jumped off a roof or lost her personality.

That latter one would probably only have taken a gentle breeze, to be honest.

Let’s make electricity

Shall we? Well, we need to.

We’re short of electricity. We have been for a long while. Things have been better recently, but that’s mainly due to the economic downturn rather than any huge increase in generating power.

So, we need more electricity so that when things pick up again (lol!), we are ready to go and there are no further instances of “rolling blackouts” or “loadshedding”.

Much has been made of the SA Government’s insistence of going down the nuclear route. Currently, we have just one nuclear power station, just up the road at Koeberg. The alleged R1 trillion deal with Russia would add several more, and also the opportunity (so the cynics say, at least) for massive kickbacks, corruption and general naughtiness.

The cynics may well be right. But their fears are not what this post is about.

Brian Molefe, group chief executive of Eskom, allegedly recently stated that nuclear was “the cheapest option” and a local fact checking website went after him on that claim. They found, perhaps unsurprisingly, that his alleged claim was incorrect. But his inaccuracy is not what this post is about.

Here’s a screenshot of a graph that Africa Check’s data generated (geddit?):

And you can see that Brian was incorrect. Naughty Brian. Well done, Africa Check.

Thankfully, one thing everyone can agree is correct is that South Africa needs to generate more electricity. Oh, and that we really can’t afford to pay any more for it. So, what exactly are our options?

There’s hydroelectric. Clean, renewable, easy, cheap. It would be lovely to run our country with electricity from mountain streams and melting snow. But we don’t have mountains streams and melting snow. In fact, we have a few issues with the amount of water we have available for anything full stop. Put simply, there just isn’t enough water to make HEP a viable option.

There’s coal. Coal is cheap, we have lots of coal and we have lots of big coal-fired power stations. But coal is filthy. It makes shedloads of greenhouse gases and a billion other pollutants that no-one wants. Greenpeace says no to coal, and it’s just about the only thing I agree with them on. Going forward, coal should not be on the table (or in the furnace) for generating electricity.

Next up is gas. It’s there with wind and nuclear as a level levelised cost. Now, I happen to know that just under the Karoo is (conservatively estimating) about 450 000 000 000 000 cubic feet of shale gas. And I’d tap that gas. We could drop coal, drop our carbon emissions and make lovely, relatively clean, relatively cheap electricity. Except the green people aren’t happy with the plan to extract the shale gas. We’ve covered this… er… “extensively” on 6000 miles… I don’t think I need to go into again. Shale gas would be brilliant for SA. But the bunnyhuggers are determined that it won’t happen.

There’s nuclear – right there. Reasonably cheap, very clean, super reliable. Look at Koeberg – running without any big problems since 1984. There may be issues about corruption, but whatever methods we choose, this is electricity generating infrastructure on a massive scale. Sadly, there will always be those opportunities.

Still, wind looks like an option. Until you do the sums, that is. Remember that the nuclear option is for 9.6GW of electricity generation. Now look at this:

At 3MW per massive 145 metre (90m hub + 55m blade) turbine, you’d need 3,200 turbines! And that’s assuming 100% efficiency. Wind farms don’t do 100% efficiency. Wind farms only do about 30% efficiency (and I’m being nice here). So basically 10,000 turbines to guarantee that 9.6GW figure. If you’ve seen the blot on the landscape that is the Dassiesklip Wind Farm near Caledon, you’ll see how much of an eyesore just 9 (nine) turbines can be. And how much space they take up.
Dream on.

Look at the left hand side of that bar chart. Realistically, you’d probably have to rule out solar on the grounds of price. Oh, and also, the ridiculous scale required:

To achieve the 9.6GW capacity planned for this nuclear thing, we’d need something about 33 times the size of the current largest solar park in the world. That would cover 32,043 hectares and would cost about $33 billion.

So, no. Nuclear might not be the cheapest option for generating electricity in South Africa. And Brian Molefe shouldn’t be saying that it is. But until someone comes up with any other viable option – and I really don’t see anything reasonable on the table or anywhere close – it might well be the best option for electricity generation in South Africa.

Whether you like it or not.

Keeping The Lights On

One of the benefits of being over in the UK recently was that I was able to pick up the latest copy of Private Eye magazine. I used to be a subscriber, but found that the postal delay rendered much of the content dated and irrelevant. If ever there was a case for a publication having a digital edition, Private Eye are it. Topical satire simply doesn’t age well.

But I digress. Often.

There was a column in it written by ‘Old Sparky’, entitled “Keeping The Lights On”. It was very interesting to read it as a SA resident. It’s probably a bit long to add into a blog post, to be honest, but I’ve never been one to abide by the petty unwritten rules around blogging, so here is it, in its entirety – I’ll see you for more comment on the other side:

WHEN the authorities make contingency plans against predictable disasters, we all applaud their foresight. Which catastrophes they are thinking about, however, can be revealing and give cause for concern; and right now the government is working on the possibility of a five-day nationwide power blackout – putting all its breezy denials of the lights going out into perspective.

As frequently noted here, energy policy since the dreadful Energy Act 2008 has resulted in the safety margin between reliable electricity generating capacity and peak demand becoming progressively and dangerously tighter. A 20 percent margin would be considered comfortable; but this winter it will only be 1.2 percent – down from 4.1 percent last year – before the National Grid takes special short-term measures.

Homes and hospitals
The grid has recently been bolstering its emergency resources with banks of diesel generators and the right to switch off industrial customers. Publicly the government always insists “the lights will stay on” – in homes and hospitals, that is. But it’s a costly, third-world way to run a grid in a supposedly advanced economy: and now we know they obviously don’t think it is guaranteed to work.

Papers seen by Private Eye indicate that the Cabinet Office and Treasury combined are planning for a scenario in which there is a five-day nationwide blackout with only small stand-by generators working. The detailed consequences they envisage include:

  • No landline telephones available to businesses or homes
  • Mobile phones with voice-only service (not data)
  • No street lights, traffic lights or public transport
  • Two-thirds of petrol stations closed
  • Shops open only sporadically and unreliably
  • ATMs unavailable, with cash running out fast

This would most probably happen in winter. It goes without saying that such a situation would also bring about ghastly accidents and loss of life, with the emergency services much constrained in their ability to cope. The implications for industry, commerce and public order are grim, too. If it’s any comfort, the German authorities – based on their own crazy energy policy – are looking at very similar scenarios.

With all this at stake, as prudent as it may be to plan for potential calamities, it would surely have been better to render the blackout scenario redundant by properly ensuring security of electricity supply. The current combination of intermittent wind farms, ageing nukes, fast-closing coal-fired power stations and mothballed gas-fired plants doesn’t do that: and privately the government knows it.

Yeah. We think that SA is the only one with problems like these. But there’s a real danger that the UK could experience some form of load-shedding this winter as well. (Regular readers shouldn’t find this news surprising.)

When similar ‘disaster’ plans made by Eskom and the SA Government became public knowledge, there was considerable disquiet and some small degree of panic (probably mainly thanks to scaremongering headlines). Sales of tinned goods reached heights not seen since 1994 and we all waiting to be plunged into dark, apocalyptic anarchy.

It didn’t happen.

Yet.

SA signed up (or didn’t sign up, depending on whom you choose to believe) for 4 new nuclear power stations, designed and supplied and ostensibly run by a foreign power – Russia. (Ironically, the UK has pretty much done the same thing with China and France.)

The cost of this SA/Ruskie venture? A tidy One Trillion Rands. It’s a lot of money, but the issues are not specifically around the cost, but (as you will read here) mainly around the safety of nuclear power stations and the potential for widespread corruption. Thing is though, the safety issue isn’t actually an issue – one only has to look at the still completely unexploded Koeberg Power Station to see that. And the corruption thing, while entirely valid, has got very little to do with this specific deal, and would be a problem no matter what large scale civil engineering project was being undertaken, and by whomever. That’s how these things work in SA. It’s sad, but it’s true.
So your plans for a ‘super clean’, ridiculously big, massively inefficient solar plant would attract the same problem. Your unpretty, flying thing killing, massively inefficient wind turbine plan will also be loaded with backhanders. But Greenpeace will probably choose to ignore that.

Large scale projects are expensive. Producing electricity is expensive. It’s something we have to accept though, because these are things that we need. People with trendy, fleetingly zeitgeist ideas like diverting that Trillion Rand to tertiary education are missing the rather obvious point that without some form of generating more electricity, there will be nothing for their newly graduated thousands to do in an economy that’s lying in small bits and pieces all over the bottom of Africa.
Yes, of course this situation could definitely have been better managed – it could still be better managed – but we need to do something, because otherwise we’re going to end up implementing that Eskom blackout plan.
And that is not a road we want to be going down.

Fracking v Solar v Wind discussion

This from the Guardian:

Researchers at Manchester University have found that fracking causes less toxicity to humans and marine ecosystems and uses less resources than solar panels and wind turbines.
Their study, which measured the environmental impacts of fracking and compared it to other energy sources, prompted a story in the Times under the headline: Fracking ‘greener than solar panels’.

What follows is a discussion involving study authors, some experts, some interested parties and some of the general public. It makes for an interesting read, but it’s quite long, so I’ve taken a couple of points out of it which I think are of particular interest. The first being this question:

What do you think we can do to make the public discussion about fracking more rational, and less emotional? Do you think it [the discussion] needs to be more evidence-based?

I may have mentioned this exact thing over three years ago, right here. And as (report author) Laurence Stamford says:

Definitely. The shale debate is almost entirely based on rhetoric and hearsay (although this also applies to most topical issues e.g. nuclear). What we’re hoping to do here is simply to add some numbers and some neutral, evidence-based discussion to allow people to make informed judgements.

This is undoubtedly the best way to make informed judgements. But there are problems with this approach, namely that (predominantly) the bunnyhugger side know that in the struggle for hearts and minds, the hearts are generally the ones that win through. Appealing to people’s emotions will always be more successful in attracting supporters to your cause, so why bother with the uncomfortable truth of facts and figures that don’t support your case?

The flip side is that those facts and figures need to be independently sourced – or at least independently audited and verified – if we are going to consider them. All too often (and not just in the case of fracking), a bit of digging reveals that research, papers and reports have been funded by organisations with a specific interest in the subject under investigation.

Then there’s the interpretation of information by the media. The Times reported this study under the headline: “Fracking ‘greener than solar panels’, which Stamford says was not what he feels the study says:

“That makes it look like we are saying that solar panels are all around worse than shale gas, which… is not really what we’ve said. We are certainly not trying to say that shale gas is greener than renewables.”

He says it would be more accurate to say:

“For certain environmental problems shale is better than solar, whereas for others solar is better than shale.”

The lesson from this one? Don’t believe everything you read in the newspapers. Who knew?

And then what factors should be considered when comparing electricity generation technologies? Well, ideally, all of them, but then how much weight should be given to each – once again, there’s no easy way of answering that.

Interestingly, the major environmental concern related to solar was not investigated in the study. According to the solar industry, the turning over of agricultural land to solar farms is the biggest environmental public and policy obstacle the industry faces.

Yep – 6000 miles… covered that one too.

All in all, it’s an interesting study – albeit that people’s views on it have already been tarnished by that Times story – and a worthwhile discussion. A reminder on what we should be striving for when considering various forms of electricity generation and that the case for “renewables” isn’t always as clear cut as the anti-frackers would have us believe.
