Three Things Thursday: 27 April 2017

*three things that make me smile: an exercise in gratitude – feel free to steal this idea with wild abandon and fill your blog [or Twitter account or Facebook page or diary or life in general] with the happy*

Inspired by Emily of Nerd in the Brain here are my Three Things Thursday.

This week I could list three hundred things that have made me happy, but here are just three.

First, lizards. We were delighted to spot some lizards in the rainforest biome at The Eden Project. They are there as pest controllers. Here is my best photograph:

Second, asking the experts. We visited the Telegraph Museum in Porthcurno the other day, deliberately timing our visit to coincide with the day that the former workers come in to volunteer each week. This allowed Mr Snail the opportunity to ask lots and lots of technical questions…

Third, industrial history. Ever since I spent two and a half years surveying the old metal mines of mid-Wales I have been fascinated by the history of extractive industries. I had a great time, therefore, visiting Wheal Martyn, a museum dedicated to the china clay industry in Cornwall. They have lots of great exhibits but my favourite was the working water wheel:

So, those are three things making me smile and for which I am grateful. What has made you happy this week?

What source?

Where does your electricity come from? I don’t mean, what’s the name of the company that supplies it, I mean, how is it generated – coal, oil, gas, wind, solar, tidal…? And does your supplier tell you?

A few years back, we switched suppliers – we had originally signed up for a ‘green tariff’ from one of the big six suppliers in the UK, but decided to switch in order to support one of the smaller companies whose focus is on green electricity and who are investing in renewables. Interestingly, this change has helped us financially. Because our supplier, Ecotricity, produces most of its energy from renewable sources, we are buffered from the vagueries of oil prices, and our bills are not rising, whilst customers of the big electricity generators are seeing significant increases.

In addition, our supplier is proud of their achievements, whilst acknowledging that they are not perfect. They are investing in renewables directly and the impact on their supplies, in comparison to the UK overall, can be seen in this table:

Perhaps my favourite part of their website is the page that tells me how the UK is doing in terms of carbon dioxide emissions and fuel mix right now:

The traffic lights on the left tell you whether it’s a good time to use electricity in terms of carbon emissions and the table on the right shows the current contributions of the different fuel sources. I’m not sure whether there are similar tools available for other countries (anyone know?). Our situation is slightly more complex than only using big appliances when the traffic lights go green because on sunny days our solar panels generate lots of electricity and it is best to use this directly when possible, but when it’s dull or dark, this tool is going to be really useful.

Centre for Alternative Technology

I didn’t think that I was going to get the opportunity to write for a few days, but then it dawned at me that being here at the Centre for Alternative Technology was too good an opportunity to miss in terms of blogging. So, yesterday I had a little wander round to take some photos of the site that you just might find inspiring…

This afternoon we are off to see the sand dunes at Ynyslas and (hopefully) visit the submerged forest that has been exposed by the recent storms.

If you want to visit CAT, it’s open to the public from Easter and located in the middle of Wales, near Machynlleth. Really, it is well worth a visit.

 

 

 

 

 

 

 

 

 

 

Greenwash and Eco-bling

No bling - we did our sums first

No bling – we did our sums first

A few years ago (wearing my ‘professional ecologist’ hat) I attended a meeting with other professionals about a development being undertaken by a housing association. One of the aims was to achieve a green accreditation – The Code for Sustainable Homes. There was much discussion about eco-building materials, insulation and all sorts of other ‘hidden’ features before we got on to discussing the more visible features. And it was at this point I first encountered the term ‘eco-bling’. You can easily understand what it means: those showy things that look good but serve little purpose. Water butts that simply divert water but whose contents are never used; wind turbines that generate so little electricity it will take hundreds of years for them to pay for themselves let alone offset the embodied energy; inappropriately sited solar panels.

The Guardian has suggested that eco-bling is “more about showing off environmental credentials to neighbours than saving carbon”. Well what do you expect from ‘bling’? But this really is a cynical view – it may be that some people only pay for eco-features for show, but I think most individuals who install renewables probably do so because they think that either these measures will save them money and/or they are doing something to reduce carbon emissions and our reliance on fossil fuels. I’m sure that many people (individuals or companies) have done the maths and are making choices for sound reasons – the same may not be true for developers wanting to convince you to buy their houses, or governments wanting you to vote for them.

Indeed, there is a lot of ‘greenwash‘ out there… and it mainly seems to be used for marketing. We can all be more sustainable by simply buying less stuff – goods that never get made have no environmental impact. But when we do need to make a purchase, I think it’s important to look behind the claims. In some ways I have more respect for a product that is honest and makes no claims about green credentials than one that spouts how eco-friendly it is when closer inspection reveals something quite different. And I accept that it can be difficult to find goods that are completely environmentally sound and/or ethical (and remember that depends on your own ethics too), but I really object to being duped.

What I want is honesty – I want to buy from a company who are up-front about their products, working conditions, raw materials, energy sources etc. At least that way I can make informed decisions and it might save me hours of internet research too!

Plugging the leaks

I haven’t written about it for ages, but one of the ways that we try to be a little bit more sustainable is by boiling the majority of our water in a Kelly Kettle. In case you don’t know what one is, I’ll let the manufacturers explain:

the Kelly Kettle is essentially a double-walled chimney with the water contained within the chimney wall.  Once the camp kettle is filled with water, simply start a very small fire in the base, set the kettle on the base and drop additional fuel down the chimney (natural environmentally friendly fuels such as twigs, leaves, grass, paper, dry-animal dung, etc.!).  The large internal surface area of the chimney heats the water extremely fast so, very little fuel is required.  The fire is all safely contained within the fire-base and the chimney of the kettle itself so, a) strong wind and rain does not interfere with the fire and b) the kettle is safe to use in many areas where open fires are not suitable

A roaring success for boiling water!

They are really designed for camping and outdoor pursuits, but we use ours at home every day… usually on the back doorstep. We sometimes light it in the greenhouse if it’s raining or very windy, but that’s for our comfort, the Kelly Kettle will work outdoors in really unpleasant conditions. We fuel it with waste paper, trimmings from around the garden (especially the willow hedge) and sticks that we collect whilst walking the dogs. We boil it a couple of times each day and store any excess hot water in two very good Thermos flasks for later use.

We have been doing this for four years now… I’m not sure how much electricity and money it has saved us, but if we assume that it gets boiled 600 times a year and that it saves us £0.05 each time, it has more than paid for itself and we’re well into profit.

I suppose that most Kelly Kettles only get used occasionally, so ours has had quite a hard life. Even so, we were very distressed a week or two ago to notice that it was leaking from one of its rivets. I’ve mentioned before how much I hate replacing things and much prefer to repair them (see this post if you want an example) so we started discussing what we could do. Our Kelly Kettle is stainless steel (we have very soft water here in west Wales, so aluminium was out of the question for everyday use) and neither of us had any idea about how this is best repaired. An internet search was in order… resulting in a link to the manufacturer’s own web site, telling us exactly what to do . Now there’s a company that I have respect for: a company who don’t want you to throw their product away and buy a new one, but who want to tell you how to make it last as long as possible.

All mended!

All mended!

As a result we have a fully functional Kelly Kettle once more – repaired with food-grade silicone sealant – and a very warm feeling about The Kelly Kettle Company of Newtown Cloghans, Knockmore, Ballina, County Mayo Ireland.

Do you know of other companies who behave like this? Because if you do, they too deserve some credit.

My radio

I like to listen to the radio when I’m cooking or planting seeds or generally pottering around, so a portable radio is essential. About ten years ago I asked for a wind-up one for my birthday – I thought that this would be great both because I would be saving electricity and I would be able to use it anywhere, whether there was a power supply or not. Mr Snail-of-happiness duly provided me with a model that was not only wind-up, but also solar-powered. Brilliant – if it was sunny, I wouldn’t even have to expend any energy!

And for several years it functioned well – mainly living on the sunny kitchen windowsill, which faces south-west. I used it for, perhaps, an average of an hour a day. But then the batteries stopped holding their charge and it had to be wound up on days when it wasn’t sunny, because it hadn’t stored any energy. ‘No problem’ said Mr S-o-h, ‘I will replace the batteries.’ It’s great to have someone about the place who understands electricity and electronics, so off he went to open it up and see what sort of batteries it needed. And then came the problem. This radio was not designed to have new batteries. The screws holing the case together were not standard and could not be undone using a normal screw driver. Mr S-o-h was not deterred and fiddled about until he got inside, replaced the batteries, reconstructed the radio and all was well. It sounds easy, but actually it took him ages.

And for several years it functioned well. But then the new batteries stopped holding their charge. Once again Mr S-o-h had to break into the casing, but now the non-standard screws were becoming damaged and the plastic of the case was starting to weaken (it had been sitting in the sunshine for eight years after all). We realised that eventually, if we kept opening it up, the radio would completely fall to pieces and, indeed, it was already no longer holding together well. We discussed replacing it, but this was not what we wanted. The idea of buying a replacement went right against the grain – we got it because we didn’t want to produce waste, so we certainly didn’t want to throw it away.

So, Mr S-o-h modified it so that the batteries live in an external holder where they can be replaced without opening the casing. It’s currently held together with a big cable-tie. I guess that, eventually, the plastic will disintegrate and we will have to construct a wooden box to keep the workings in. The tuner isn’t very good any more, so now we are confined to a single radio station, unless we embark on a bit of a struggle. But it’s still going.

We are now so attached to this radio that it cannot be allowed to die… I just wish that when it had been built, the makers had the ethos of sustainability, rather than deliberately making it difficult to repair and maintain. I guess that we just aren’t very good consumers from the perspective of manufacturers.

Solar, wind-up radio in its latest incarnation… still going strong
