Lightbulbs, windmills, common sense and Ecobuild

Monday, March 9th, 2009

I found myself at Ecobuild last week, not so much for the eco as for the build.

Thought I’d listen in to a debate they were having that day – here’s the info:

11.45 – 12.30   Climate change – behavoural change
Rt Hon Michael Portillo
, Conservative Minister for eleven years, writer, and broadcaster – BBC 1’s This Week programme and Radio 4’s Moral Maze
Dr Julian Baggini, British philosopher and author; co-founder and editor of The Philosophers’ Magazine
George Marshall, Founder of COINet (Climate Outreach Information Network); author of Carbon Detox
Prof Herbert Girardet, Director of Programmes, World Future Council; author, consultant, filmmaker

Hosted by: Matthew Parris  political   journalist, award winning writer and former Tory MP

The format was supposed to be a brief introduction of 5 minutes or so by each of the speakers, followed by a debate, then a Q&A.

Unfortunately, Parris let his chum Portillo deliver a 20 minute monologue, meaning that everyone else had to have a go too. Didn’t leave much room for debate, or questions. Again, Parris let the questioners ramble on with opinion rather than question. I had a quick question I never got to ask, but it would have a been a response to George Marshall’s point of:

“People say that China is building a new coal-fired power station every week. I mean, really, who’s putting that sort of thing out there?”. He said it dismissively, as if it wasn’t true. Which, of course, it is. Then went on to suggest that we shouldn’t worry about China, we should concern ourselves with stuff like cutting the little plastic windows out of enveloped before we recycle, and almost suggesting we do nothing, ever, just in case it uses carbon. I just wanted to ask “are you saying that a: it’s not true, and b: China doesn’t matter”?

Because China most definitely matters! One single day of a China coal-fired power station is more than all the people in an entire town doing all the right green things. For their entire lifetime.  I want to know that every action on my part the government force me to do, has an opposite reaction by that government against the massive polluters like China.

I far prefer the George Monbiot approach of campaigning against stupid stuff like 500w £2000 rooftop windmills which only give “green” energy a bad name.

As with all things, you have to use a bit of sense. I read an opinion piece recently (I forget where) but the point was that climate change may or may not be happening. And even if it’s not, being efficient isn’t a bad thing, is it?

What’s the difference between living in a town and commuting to work in a:) a massive 12mpg gas guzzler b:)A hybrid Lexus c:) A smart looking sporty little 75mpg diesel hatchback?
With a:) you’ll be pouring money into terrorist states in the middle east and everyone except Rush Limbaugh will think you’re a massive wanker; with b:) you’ll only being massaging your own green ego as it still only does 35mpg, and with c:) you’ll save a load of cash, get their just as quick and safely, have more space to park, pay less tax and do the journey probably a bit quicker.

Same goes for lightbulbs – you always wonder what kind of dick writes these things about ES bulbs “costing £9 each” or “polluting landfills with mercury” or flickering or starting slowly.
Modern Philips “instant on” ES bulbs costs 25p each, only faulty ones flicker, and any mercury in them is more than offset by the mercury emmisions not put out by generating the massive amounts of electricity to heat up a coil of wire in an inefficient design over 100 years old.

More on the mercury business from snopes and wikipedia. Needless to say, the bottom line is that a CFL is just a mini version of the same standard flourescent tubes that have been lighting schoolrooms for 30+ years now, therefore, most of the hysterical Daily Mail bad science is a crock of shite.

Going back to George Marshall, I’ve also read him saying that if a family can’t afford to go to Europe on the train, they shouldn’t go. That’s just so elitest! It’s not the family flying once a year to Spain in a modern plane with a per-passenger efficiency of that of a similar car journey. It’s the pointless weekly business-class flights to-from New York for a 2 hour meeting. And as anyone who’s ever been to any sort of meeting, almost all meetings could be replaced by some hot air, or at most a short email.

In summary – I’m happy to go with almost all the world’s eminent qualified peer reviewed scientists in believing that the current climate-change is aggravated by pollution, rather than go for the voodoo-blogging crystal healing conspiracist bloggers who think it’s a global conspiracy.

However, it’s all about degrees and balance, and both sides of the argument need a little perspective:
Greenies – stop complaining about large, efficient wind-farms, while putting pointless, dangerous devices on your house.
Anti-greenies: Stop (for example) pretenting large wind-farms only provide a few % power – we’re not so stupid to believe that they’re all sited in one place and the wind only blows in that one place at one time (which I really did see a whole argument based on).
Governments: Stop taxing random things pretending it’s for a green agenda
And carbon trading companies: Stop lying to people!
There – that’s the world set to rights. Next?

Another look at domestic wind turbines

Friday, August 22nd, 2008

Just an interesting collection of articles for anyone thinking of installing a domestic wind turbines or who thinks that the government is doing the right thing by throwing away millions in grants for these pointless adornments of the gullible (btw, I’m not against “proper” wind turbines)

Channel 4 to be censured for fake “documentary”.

Sunday, July 20th, 2008

In March 2007, Channel 4 screened a fake/hoax documentary (fokumentary?) called The Great Global Warming Swindle.

And a lot of people fell for it. Unfortunately, some of the more, shall we put it “cerebrally challenged” saw fit to embarrass themselves into using it as an argument.

In the style of Obie from Family Guy: “Well, uh….there’s uhhhh…this man I uhhh…know from the pub and …uhh.. he saw this uhhhh…documentary on … uhhhh … channel ummmm four …. uuuuhhhh … vote Republican!”.

UPDATE: 25th July – Marcus Brigstocke from The Now Show comments on the judgement (more at the bottom of the post)

Well, you get the idea. Anyhoo, they had their asses whipped by the regulator!

From The Times:

A Channel 4 documentary that argued that global warning was a fraud is to be criticised by the media regulator.

On Monday Ofcom is expected to publish a long-awaited report that upholds claims by some of the scientists who appeared in the programme last year that they were misrepresented.

The Great Global Warming Swindle, which aired in March last year, has been accused of downplaying the threat in the public mind. It sparked an outcry among environmentalists and many campaigners argue that the programme has contributed to people believing that the threat is not real.

It is understood that complaints by Carl Wunsch, a climate expert at the Massachusetts Institute of Technology, will be upheld

It misrepresented evidence about the threat of global warming and that it rehashed discredited arguments and skewed data and charts to make its arguments stand up. In the closing moments of the program a voiceover from the climate change sceptic Fred Singer claimed that the Chief Scientist of the UK had said that by the end of the century the only habitable place on the planet would be in the Antarctic and that “humanity may survive thanks to some breeding couples who moved to the Antarctic”.

Sir David has never made such a statement. It is thought that Mr Singer confused the comments with those made by the scientist James Lovelock, who infuriated many colleagues in the science community when he publicly questioned global warming.

From The Guardian:

The detail of the ruling is expected to criticise Channel 4 over some aspects of the controversial programme, made by the director Martin Durkin.

The programme was criticised by scientists, who claimed it fundamentally misrepresented the evidence about global warming, that it rehashed discredited old arguments and manipulated data and charts to make its case.

I heard Durkin being interviewed once – what a complete cock! When they put one argument to him, he threw his toys out of the pram and started being abusive.

And here it is on Youtube – but I disagree with him about China, though. China is by far the greatest threat and will overtake the USA as the world’s worst polluter (by country and capita) within a year or two.

Green / alternative energy. The good and the bad.

Thursday, July 17th, 2008

From time to time, I get someone saying “all renewables is rubbish, isn’t it?”. The most recent site I got pointed at was:

http://www.greenliving.co.uk/Articles/theeconomiccasef.html

I read that site and hung my head in despair. Now, we all know that small scale wind turbines currently don’t pay for themselves, either in carbon footprint payback or financial terms. Would it be great if there was someone who had found a way of making it work out?! Except, as I was reading through, I couldn’t help thinking “what about this? what about that?”. I was twitching to find the “contact” link, when my questions were answered at the bottom:

http://www.greenliving.co.uk/Articles/theeconomiccasef.html#FAQ

It appears “the economic case” puts aside small things like depreciation, maintenance, replacement of batteries, installation costs, etc etc etc.

So, let’s have a brief look at a summarized version of the Q&A (I have abridged but not edited or changed any words)

Q. You haven’t considered the cost of borrowing money to fund the installation.
A: I didn’t factor in the cost of borrowing as I wanted to keep the article simple.

Q. Do the battery banks not need replacing periodically?
A. This is a complex area whose costs I cannot accurately quantify

Q. [The article] does not deal with storage issues
A. Regarding how electricity is stored, I deliberately kept that side of the article simple because I did not want to obscure the main argument.

Q. Does your calculation include installation costs?
A: No, because these are difficult to quantify.

Q. What would the planned maintenance costs be over 20 years?
A. Difficult to say

Q. Are there any maintenance or insurance costs associated with the turbine?
A. A|l turbines need regular preventative maintenance, [...] I have not included these costs.

Riiiight, so as long as you don’t actually factor in any real-world costs, it works out perfectly!

For those of us trying to make a living out of viable energy (solar thermal etc), these kinds of sites don’t help at all – they just make the whole industry look bad.

BTW – grants paid since inception of scheme:

Not very inspiring.

I also read a book, “How to live Off Grid”. Except, it’s not very “how to”.

I’m afraid I have to agree with this review from Amazon (I’d gone there to write almost precisely the same!)

One of the lesser problems with this book is that the author spends too much time talking about himself instead of the subject. For example he writes in detail about his difficulty in finding parking space when he visits one of the off- grid people. He also brags about getting gadgets for free and talks far too much about his family. He seems to brag about rather than describe his off grid place in Spain. He then says that he can not afford a house in the country in addition to his expensive 2 homes and his van.
The very worst problem is that the book is badly structured, in that the details of how each off grid community works is in a separate chapter to the general description of it and it’s inhabitants. It is hard to flick back and forth between chapters. The quality of writing is not the best.

The only saving grace is a very good tiny section at the beginning about the history of the grid. There is also possibly useful bit in the chapter about planning permission at the end.
There is also the odd thing, that Nick Rosen admits himself, about the irony of him choosing to drive a van to be “off grid”. I was disappointed.

Additionally, there are some glaring typographical and factual errors – weird things seem to happen with random brackets in several places, and p334 – energy saving bulbs do NOT cost £3.50! They are between 40p and 60p each. Well, the Philips ones do, anway.

Good that it is FSC paper though – I have first edition (2007).

I suppose it’s a good try – but it’s embarrassingly obvious that he must have been on “pay per plug” for the Vodafone 3g card :)

Finally, check out this bit of nonsense from the local paper in the letters section:

Image this – school mums are delivering their little darlings to school past eco-friendly homes that have wind turbines.
A typical British mini-tornado blows up and demolishes a wind turbine.
The knife-like blades shoot about as if from a whirling dervish killing or maiming several of those mums.
Come on! Roll out the nuclear future. The people of Reading cannot wait any longer for this.

TWO politicians speaking sense in one week?!

Tuesday, July 8th, 2008

Admittedly, they are straight from the department of the bleedin’ obvious, but in the same week that Gordon Brown pointed out that

…each household could save £420 a year by not throwing away edible food. Approximately 4.1 million tonnes of food which could be eaten are disposed of each year, the government estimates.

David Cameron said:

…that some people who are poor, fat or addicted to alcohol or drugs have only themselves to blame.

He said that society had been too sensitive in failing to judge the behaviour of others as good or bad, right or wrong, and that it was time for him to speak out against “moral neutrality”.

“We talk about people being ‘at risk of obesity’ instead of talking about people who eat too much and take too little exercise,” he said. “We talk about people being at risk of poverty, or social exclusion: it’s as if these things — obesity, alcohol abuse, drug addiction — are purely external events like a plague or bad weather.

“Of course, circumstances — where you are born, your neighbourhood, your school and the choices your parents make — have a huge impact. But social problems are often the consequence of the choices people make.”

Blimey. Personal responsibility? Whatever next?! Not sure a country infantalised by ZaNu Labour is ready for this kind of thing….

RICS report claims Solar Thermal energy takes 208 years to pay back

Saturday, October 13th, 2007

I saw a report in today’s (Saturday 13/oct/2007) Times, Mail or Telegraph that Solar Thermal energy takes 208 years to pay back. In fact, ALL of the figures in the report are drastically wrong – the figures and costs quoted are 5-8 times greater than “real world” quotes, and the figure for solar energy is completely incorrect. As member of the Solar Trade Association (STA) , Solar Powered Services abide by the strict ethical guidelines for both marketing and suitability of solar products. I’ve contacted the STA and RICS for explanation, and look forward with interest to see where they go the figures from. Click the image below and you’ll quickly see just how wrong the figures are.

Global Warming – suddenly it all seems a bit futile…

Tuesday, May 15th, 2007

From The Independent...

In the next 24 hours, deforestation will release as much CO2 into the atmosphere as 8 million people flying from London to New York. Stopping the loggers is the fastest and cheapest solution to climate change. So why are global leaders turning a blind eye to this crisis?

The accelerating destruction of the rainforests that form a precious cooling band around the Earth’s equator, is now being recognised as one of the main causes of climate change. Carbon emissions from deforestation far outstrip damage caused by planes and automobiles and factories.

The rampant slashing and burning of tropical forests is second only to the energy sector as a source of greenhouses gases according to report published today by the Oxford-based Global Canopy Programme, an alliance of leading rainforest scientists.

Figures from the GCP, summarising the latest findings from the United Nations, and building on estimates contained in the Stern Report, show deforestation accounts for up to 25 per cent of global emissions of heat-trapping gases, while transport and industry account for 14 per cent each; and aviation makes up only 3 per cent of th

I heard some pillock on BBC Radio 4’s otherwise-excellent comedy, The Now Show, on a great rant, the gist of which was “how dare the west criticise China for building a new coal-fired power station every week.”

Well, you know, if I’m going to be recycling my lightbulbs and reading low-energy newspapers to save my 1 gram of carbon, I think it’s pretty fair to put the onus on so-called “developing” countries to do their bit to.

The whole air-travel thing is a big-old ruse for a stealth tax. There was a hole in the coffers. Gordon wanted a billion quid.
Let’s have a new tax – and invent carbon offsetting while we’re at it.

And this guy’s gonna be the new PM…..we’re doomed!
