One thing we have learnt this week

Today the UK Energy Bill deal has been announced after protracted negotiations between the coalition partners.  Reactions have been mixed and quite a good explanation can be found here .  As a compromise its got its good and bad points.  Essentially an electricity decarbonisation target has been dropped until after the election and we know which side each coalition partner will fight that on…  However, the overall climate act carbon budgets still remain.  In theory there might be a dash for gas but since Labour is sticking to its total decarbonisation by 2030 investors may not be so keen to build new gas power stations knowing they could not get through their lifetimes. What’s been agreed is generally regarded as pretty good news for renewables and RenewableUK were apparently full of praise.  Whether its good news for nuclear remains to be seen.  We will know next week when the strike price to be paid for electricity generated by each technology is announced.  The current rumour is 10p/units tops for any technology, but I would doubt if new nuclear can be built for anything like that. If there is a dash for gas which succeeds then we will all face much higher bills, but conversely this is good news for renewables, especially micro-generation.  Finally this takes us up to 2020- what happens after that is anyone’s guess but by then PV and onshore wind will no longer require subsidy and probably offshore will be the same.

What’s certain is that your bills are going to rise.  The more gas and nuclear that’s in the mix the more they will rise.  I will be returning to this is a future blog post.

Good stewardship and LED’s

I have recently bought some more LED’s. With the EU’s incandescent bulb phaseout complete (at least for 240V – a low voltage bulb efficiency mandate is mooted) the manufacturers have really worked on technical improvements to alternatives and prices have also fallen. Compact fluorescents and LED’s have improved with better light and in the case of compact fluorescents faster start-up times. In addition LED’s are being produced at higher power outputs and are able to replace higher wattage bulbs. I’ve noticed all this over the last few years. I bought some very low power LED 240V candle LED’s and the light was still slightly blue. When mixed with other light types this was not noticeable, but you certainly would not want to use them solely to light a room (in any case the light output was too low). Now 25W light output equivalent (using just 5W) bulbs are available. I’ve purchased two.

In terms of light quality the manufacturer (a very well known multinational) has got it right. The light is indistinguishable from an incandescent bulb. This is a remarkable technological feat. Also with LED’s there is no warm-up time. The cost is still high however. I paid £12. What I was wondering was how do the economics stack up?

There are two alternatives to LED’s; compact fluorescents and GLS halogens which use about 30% less electricity than a classic halogen bulb, but a lot more than a compact fluorescent.

LED versus GLS. Cost of “25W” LED £12 (5W consumption) cost of GLS “35W” £2.95 (28W consumption). They are not quite “like for like” but this is near as can get and these are the bulbs I’ve actually bought for lighting my daughters room via spots (gradually using more LED’s and compact fluorescents). The crude economics are better than I thought. GLS bulbs are (like normal halogen ones) not incredibly reliable. I reckon they last 6 months at the use they get, so it looks like a payback of 4 years (not taking electricity savings into account).

The other alternative is a “51W” compact fluorescent that uses 12W of power and costs £5.95. Again the comparisons are not exact, but this is one I have bought in the past for this use. Compact fluorescent bulbs last a lot longer than halogens, so if you are considering which one of the two to buy on cost grounds you should buy the compact fluorescent. Compact fluorescent bulbs longevity makes them in theory a economic challenge to LED’s. They can work for many years, we had an outside one that lasted 15 years at least. However, we have also had some fail and I’m going to stick my neck out and suggest that a compact fluorescent will have half the lifetime of an LED, making the economics merely on bulb replacement even stevens.

Of course for a full analysis we need to take into account the relative amounts of electricity used. For this I’m going to have to make some assumptions about usage. Assumption one is we import the electricity used rather than produce it ourself on-site. The second assumption is that the usage by my daughter for each bulb is 5 hours per day. This is on the low side, but I’m being conservative. Third that electricity prices won’t rise (or fall – although this seems less likely). Lastly the economics will be calculated for one bulb at a cost of electricity of 16.4p/KWh (which in two weeks time is what I will be paying). So per year I calculated the running costs as the following;

GLS 5 hours x 365 days a year x 28W/1000 is 51.1KWh a year @ 16.4p/unit making the cost £8.38.

Compact fluorescent 5 hours x 365 days a year x 12W/1000 is 21.9KWh a year making the cost £3.59.

LED 5 hours x 365 days a year x 5W/1000 is 9.125KWh a year making the cost £1.49.

Since I’ve only partly bought energy efficient bulbs for monetary reasons and never considered the economics before I have to say I’m stunned by the results. The LED compared with a GLS bulb pays for itself in less than a year taking into account both projected failure rates and the cost of running them. Comparing the LED to a compact fluorescent isn’t as good with just over £2 a year difference in the price of running them its going to take 6 years of running costs to close the gap. However, remember that compact fluorescent will need replacing over the lifetime of the LED and a simple calculation suggests if you use it more the payback is faster. If the usage was double the payback would be three years. Of course the opposite is true if you use a light very little then the economics of the extra cost looks terrible.

My parents church has replaced a failed outside light with an LED cutting the power consumption from 500 to 50W. Since its on a lot the economics almost certainly stack up. My church has bought some LED stage lights and intends buying more. However, the remainder of the lighting is either 12V fed by transformers that are incompatible with 12V LEDs or compact fluorescents (we have some LED’s in our entrance). Is it good stewardship to replace our compact fluorescents with LED’s? In my view it is and we should replace them gradually as they fail. Please let me know your views and experiences. Neil

One thing we have learnt this week

I would dispute the word “learnt”, but what has been doing the rounds here is the fallout from the latest World Energy outlook from the International energy agency (IEA). The UK press has been full of America becoming a net exporter of oil and gas and and overtaking Saudi Arabia as a producer.  Natural Gas is said to be too cheap to meter in the US and we should all start fracking etc.  I have to say I don’t completely accept this hypothesis (as you will not be surprised).  I will be reading up on the latest findings and writing a blog entry this coming week on this.  I have downloaded some reports to read, but I will leave you with the following for now.  First, if you drill down (pun intended) into the summary of the WEO report its not quite as optimistic as has been reported, second unconventional oil and gas is more energy intensive and therefore more expensive to extract.  Peak oil is not just about running out of oil, its about running out of cheap easy to extract oil.  The cheap easy oil has peaked, in previous reports even the IEA accept that.  Therefore whilst I might accept we are at the top of a broader oil peak than was previously thought, I still think we are around the summit.  At the moment I have not seen sufficient evidence to change my mind.  Therefore “No oil in the lamp” is still very relevant and will continue to be so.

Neil

PS. I would be interested in knowing how much US readers are paying for their natural gas on the gas grid.  Mine is going to go up in a few weeks and I will be paying 8 cents (including 5% sales tax) per KWh.

Harvest celebration

Our eco-congregation group wanted to involve more people, and since we’re a small church we can manage to involve most of the congregation if we find a good idea!

Sourcing and using locally grown food seemed like a good focus for our celebration of harvest. There’s several good gardeners amongst us, and some of us belong to a group which encourages choosing locally grown produce. We suggested ahead of the date, that at our celebration of creation, we would like to have a bring and share lunch, using specifically locally grown or sourced ingredients.

The ministry team created an all-age worship liturgy, using material from Christian Aid about access to land for honey gatherers in India. This was introduced with a ‘taste test’ of sweet honey and sour vinegar to intrigue the kids. For this valuable and nutritious food, the honey farmers need to have local access to the forests, free from harassment by officials who try to deny them land rights. So we were reminded that for some, access to local food is a necessity, not a consumer choice.

After celebrating creation, giving God our thanks for the earth’s resources, and coming to a new appreciation of what difficulties are involved in how some of these resources are harvested, we cleared space for our celebration lunch. Delicious and imaginative food appeared, and lively conversations flowed as people compared what they had grown and how well (or not) their plants, trees, bushes had flourished. And how their recipes had made the best of what was harvested. Lots more taste-testing!

My favourite moment was when a 4 –year old friend showed me proudly the salad of fresh rocket grown by him and his mum, beautifully decorated with marigold petals.  Given our dreadful summer with so much rain and so little light, tales of woeful yields were predominant, but none of us went hungry – unlike some in areas of the world seriously affected by climate change.  We also contributed fresh ingredients and tinned food to our celebration display, which were taken to St Catherine’s convent, for their food for the homeless project.

2062 and everythings fine

I was going to blog about something else – but that will have to wait. Larry Elliot in the Guardian has written an interesting article . In it he happened to mention a report by the OECD which purports to predict economic growth forward to 2062. I needed a laugh so I downloaded it. Of course its an economic report written in economic language, such as this;

“The growth scenarios for the global economy over the next 50 years are shaped by developments in education, technological progress and labour force participation based on a framework in which GDP per capita in each country is expected to converge to the long-run path that is consistent with its own endowments, policies and institutions”.

A prize to anyone who can tell me what the second half of the sentence means. Or the very next one;

“Once this path is reached, all countries are expected to keep growing at the same pace determined by the worldwide rate of technical progress.”

However, the main problem is that the report makes series of apparently unmerited assumptions.

“Once the legacy of the global financial crisis has been overcome, global GDP could grow at around 3% per year over the next 50 years.”

There is surprisingly little basis for this factoid in the report. However, the main problem with the report is not so much what it puts in (the usual prevailing trickle-down neo-liberalism rubbish that got us into this mess), but what it leaves out. Astonishingly there is no mention of resource depletion or in particular peak oil. We can all argue about when this may take place and in “No oil in the lamp” we put forward some alternative views. Despite the latest World energy outlook (for criticisms of the this viewpoint see our very first blog entry “Is peak oil a myth”) we think we are pretty much at the top of the oil peak. However, to imply that by 2062 this won’t have happened seems quite frankly-well words fail me. But we apparently needn’t worry because after 2030 there will only be a 1% increase in oil prices every year. We are obviously going to be swimming in the stuff and floating on gas as well (all of the unconventional variety). Everything will be fine we will be humming along on a sea of oil at 3% a year, frying the planet. Yes, that’s also left out. Not a single mention. Climate change is also going act as a growth limiter. We can see that with this years weather. Even if we cannot attribute each individual act to climate change, this type of extreme weather is going to become more frequent with damage to livelihoods and crops. They call economics the dismal science and after looking at this report I can see why.

“In praise of slow” by Carl Honoré.

Honoré is a Canadian journalist living in London. In the year 2000 standing in an airport queue he realised his whole life was lived at breakneck speed. The catalyst for this thought was the advert he saw for condensed children’s books (that you can read in 1 minute). As the queue snaked forward he put down his newspaper and decided he’d gone completely insane. He and everyone he knew were dominated by what he calls the “cult of speed”. The book came out of his desire if not to slow down completely, then rebalance his life. After a chapter looking at why we should slow down the book smoothly moves through the following areas of living; Food, Cities, Mind and Body, Medicine, Sex, Work, Leisure and Children. The author taking part in activities and speaking to practitioners in each area.

The only aspect of the “slow movement” (and as Honoré says there is technically no formal slow movement) I have heard of is the “Slow food” movement. This was formed in Italy when McDonalds opened a branch in Rome by the Spanish steps. To many Italians this was like the Vandals sacking Rome again. The slow food movement has now spread worldwide and has three aspects to it. The first is as its name implies eating more slowly and savouring and enjoying food (this the book informs us can help loose weight). The second which Honoré describes has an ecological aspect to it, that is growing food locally and organically and slowly. This is unlike much of modern farming where everything is bred and fed to grow as fast as possible with deleterious effects for us, the environment and the livestock. The last aspect is related to locality, protecting and encouraging artisanal foods. The front line of the slow food movement for most of us is deli’s, farmer’s markets and small artisanal producers (in the UK this area is booming, cheese and beer are two examples of these).

There is a problem with all this though. That is, high quality food is expensive food. The author does attempt to counter this. One of his arguments is that some foods such as fruit, are cheaper at farmer’s markets. Another counter argument he makes is that cooking food yourself is cheaper than ready made meals. Unfortunately this is not always true. The one factor he does leave out from the cost point of view (though he mentions it for other reasons) is that of growing your own. This is undoubtedly cheaper than buying food, especially with the price of food having soared over the last 4 years or so. Ultimately Honoré thinks we have to be prepared to pay more for good food. My view is slightly more nuanced in that I think we be forced to pay more (because of peak oil with all agricultures dependency on the black stuff). He also thinks that small scale slow farming maybe the solution to feeding the world in the future. By and large so do I. The problem is all this will hit the poorest hardest and some solution will have to be found for this. I’m sure churches have a role to play here setting up community gardening schemes.

The Cities chapter is highly relevant to the subject matter of this blog. This chapter looks at examples from all over the world from again Italy with it “Citta Slow” movement to “New Urbanism” in the US. Broadly speaking most of the measures involve either restricting car use, or designing urban environments to reduce the dominance of the car. The “Citta Slow” movement is very allied with a the slow food movement and has many of the same aims of localism, but also creating locations for people to hang out with one another as well as green spaces. New urbanism believes in designing these features in, the example given of Kentlands in Maryland has been designed so that all the needs of the community are within easy walking distance. Plenty of green space is provided and the houses are designed with front porches so that community cohesion can be built. The problem as the the “Citta Slow” movement has found that this is not easy to do in existing cities. Here Portland may offer a vision with redesigned urban centres and a light rail system.

The book covers almost all areas of life, including mind/body. This chapter majors on meditation. By this we are talking about TM not the Christian discipline of mediation. For Christians this is where the book began to get a bit difficult (in the introductory chapter he actually quotes from the gospels a few times). However, some of the physical exercise ideas are very interesting and make sense, such as doing exercises very slowly. Again the chapter covering health from a Christian perspective is tricky with lots of alternative medicine. One of its major themes though is about slowing down the whole medical process of diagnosis and treatment and this does make sense in some instances (for example having a much longer consultation between Doctor and patient).

I’m going to say very little about the chapter on Sex. Mostly because many people I know maybe reading this. Its not a very titillating read but continues the new age theme and doesn’t have much of use to me personally and the bits that are I’m not going to share with you…

The book finishes off with chapters on Leisure and Children. The leisure chapter is again relevant to the post oil world. We all need to take time out from our increasingly frenetic lives and for example garden, learn to make something or listen to music (and switch off the television or computer/mobile phone). And talking of music, Honoré claims even this has speeded up and performances of well known classical pieces are faster than the composers envisaged. He also describes a slow performance of a piece of music by John Cage that is not due to finish for 639 years after it had started. One of my children had heard of this performance.

The slow child chapter is perhaps the least satisfactory chapter. The problem of children having their lives filled with activities is one I recognise. I know children who are never allowed to rest being shunted from one activity to another and as he says this is particularly true of privately educated pupils. However, its difficult to stop this when your own teenager wants voluntarily to do this. Nor do I think that the UK’s state schools do not “hothouse” (one of his solutions is to move your kids out of the private sector). Whilst testing at primary level has been abolished in Scotland and reduced at all levels in England and Wales I remain unconvinced that “slow learning” has gained any great traction since the book was published. The authors other remedies, that of alternative private schools such as Steiners and home education are never ones that have appealed to me. [Note to US readers the reasons for home education are completely different in the UK, its generally lefties who think state education is too pressured, there being enough private schools with a Christian “ethos” to satisfy this small demand].

The book is an easy read and well written. There is just one general niggle, all the references in each chapter are not numbered but are collected at the end of the book. This means extra work for the reader if they want to access them. So where does this leave us? In my view this book has a high degree of relevance to the concept of peak oil explored in our book and this site. This is despite the fact that its not specifically mentioned. Oil has given us perhaps too much choice of how to fill our time and arguably not always in a good way. Whilst I have reservations about some aspects of the book, its had quite a profound effect on me. I’m trying to eat more slowly with more local food and slow my exercise regime down at the gym. I’m also trying to read more and have dusted off my guitar.  There is much for Christians in this book to sit up and take notice of.  As Jeff Rubin said in “Why Your World Is About To Get A Whole Lot Smaller”, your local community is about to become very important.  Most Christians have ignored the issue of peak oil, but churches should be set up for coping with it, since they should be a local community with links throughout their local community.

What I have discovered since starting this review is that there is a book called “Slow Church” coming out next year (published by of all people IVP!), see http://www.patheos.com/blogs/slowchurch/ for details. I cannot wait to get my hands on it and will review it here.

I will leave the final word to Honoré, he says;

Tempted and titillated at every turn, we seek to cram in as much as much consumption and as many experiences as possible… The result is a gnawing disconnect between what we want from life and what we can realistically have, which feeds the sense there is never enough time.

One thing we have learnt this week

I could have mentioned a quote from our book went viral on twitter, but I’m going to be more theological this week.  This article is not new, but I only found it this week.  Its by Walter Brueggemann and entitled “The Liturgy of Abundance, The Myth of Scarcity”.  It fits in very well with our books theme.  Using a wide range of scripture including Genesis 47 Walter Brueggemann challenges the “The Myth of Scarcity” i.e. the idea we never have enough in the way of material processions.   As it happens Genesis 47 is something that I have been reading about in my own studies this week.  Its a little known passage (read it and you will see why) that I had not noticed until I was doing some reading for our book.  Joseph saves Egypt from famine but a very high economic and social cost.  As we ride down the oil peak we must ensure we use the opportunity to build a more equal society.  Anyway the whole article is well worth a read.  What do we regard as important? 

The original link is from the “Slow Church” blog, the link is on our Facebook page and that site is well worth a visit.  Like us on FB.

Eco building without the eco bling.

A few years ago I was shown round a state of the art home, designed, the owners informed me, to be ecologically friendly. They had a ground source heat pump but I was not convinced that the efficiency gains from this would counteract the expense of heating all the rooms with north facing glass walls. The bath carved out of a rock from Bali was beautiful but made me wonder just how much hot water it would take to warm up such a massive natural heat sink.

After two years of planning, sourcing, contracting and building we have finally finished our own eco build project- a substantial extension to a small listed gatehouse. It does not look particularly green. There is no wind turbine, no heat pump, no solar panels. We considered these options but given the location of our house, the benefits didn’t go far enough to balance out the embedded carbon and other environmental costs. Instead we have focused on more basic technology and simple science principals to guide our decisions on everything from room layout to materials to colour choices.

Structurally it’s basically a polystyrene box with a wooden frame. The lightweight materials mean less concrete in the foundations. Cement production is a big source of carbon emissions. Without windows, the extension would be so insulated that we could heat it with our own body warmth. Glass is a poor insulator and even good windows (we have gone for triple glazing with a low e coating and Argon fill) leak heat, so we have gone for fewer windows than found in many modern buildings. The exception is the sunroom which has a south facing glass wall. This is great when the sun is shining but leaks heat when it’s not, so we have large sliding doors partitioning it from the rest of the building. Our polystyrene walls are great for insulation but useless for storing heat, so our sunroom has a dark slate floor and a plastered stone wall (part of the original building) that we have painted a darkish colour. The slate and the wall will absorb and store the heat from the sun.

We tried to use local or recycled materials where possible. The slate in particular presented a sourcing dilemma: the price of slate is inversely proportional to the distance it has travelled, with Chinese or Brazilian being the cheapest. In the end we went for Welsh, but this was tricky to source and was the element that held the whole project up. Our architect had some reservations about our other flooring choice: maple boards recycled from a school gym floor (complete with games court lines). But the engineered joints were still good, it was straightforward to fit and looks great. It was also much cheaper than new wood flooring of equivalent quality. For our rainwater harvesting we bought a 120 gallon oak sherry barrel, for a similar price to the plastic equivalent. On the cladding, aesthetics got the better of us and we fell for the look of red western cedar over larch. This was a problem for us since most cedar is sourced from Canada or Siberia, whereas Scottish larch is locally available in abundance. We were overjoyed therefore when we got a message from a friend who owns a sawmill in Ardnamurchan- he’d just got 50 tonnes of cedar from a local road clearing exercise- were we interested? We jumped at it.

Ultimately the eco-credentials of our house will depend on how we use it. I’ve bought a timer with an alarm, set to go off if I stay too long in the shower. We don’t intend to use our sunroom on winter nights and cool overcast days. I work from home, but during the daytime any heating will be limited to my small study, which like the sunroom has been designed to maximise passive solar gain. And when that fails I will resort to the tried and tested green technology: woollen underwear.
