Green living

by Julian

Modern consumerism and its effects on the world’s oceans has been mentioned in recent blog posts by Martina (Leviathan and Behemoth and Picking through the plastic). A lot of energy is required to power our convenience filled lifestyles – energy mostly supplied by the increasingly more complicated and risky extraction of fossil fuels. The ever growing quantity of carbon in our atmosphere has been demonstrated, by scientific methods which show a characteristic isotope fingerprint, to be partly a result of the burning of fossil fuels. The related warming of the planet produces even more atmospheric carbon. It looks like we have tipped the balance and are warming the planet at a faster rate over the last half century than at any time in the past few millennia (this is shown by methods such as Arctic and Antarctic ice core studies). As a former geophysicist and glaciologist, who has worked with climate and ice core scientists, and published academic papers on the topic, I have some insight into this and am not glibly stating stuff presented in the mass media.

I have always been conscious of the need to save energy and resources but I have rarely acted on this with any serious effort. However, I have started thinking about how our current lifestyle onboard Carina has caused us to adapt in ways that seriously curtail our use of non-renewable energy and resources. Being at anchor and living on a tight budget forces us to do this.

Here are some of the ways we have minimised our non-renewable resource use:

We have an 80W solar panel. Summer in southern Europe provides plenty of sunlight, but our panel is not sufficient to run our fridge, charge our computer and run the domestic and navigation lighting. We have to be selective about our electricity use. The fridge was the first thing to go. We don’t need it. Instead, we buy small quantities of fresh food every day and use the fridge as a storage space.

As our light bulbs and fittings failed I started to replace them with LEDs. Now all our main domestic lighting uses LEDs and this has cut electricity for lighting to less than 20% of previous use without cutting down on light. In fact, in some cabins we now have better light than before. The latest technology in LEDs has fast created a whole array of options from harsh white light to softer light and bulbs are produced for all sorts of DC light fittings.

Last year Martina and I decided to trade in our four-stroke Yamaha outboard motor for a small two-stroke Mariner, partly because the Yamaha was becoming unreliable and partly because Martina could barely lift it, so getting it from Carina into the dinghy was a nightmare. An advantage of the trade in that I hadn’t considered is how little fuel a 2-stroke engine uses. Motoring twice or even three times a day between Carina and the shore, often against a strong current, and with four people aboard the dinghy, a 5-litre can of petrol lasts two weeks.

Next comes water use. At anchor we have to conserve water and we switch from electric water pump to foot pump, which minimises our consumption. It’s amazing how little water you actually need to brush your teeth, cook food or wash the dishes. Another revelation this year has been digging out the old solar shower. We can enjoy a good hot shower in the cockpit using very little water, heated directly from the sun. Sometimes the water gets too hot so we have to be careful! We also handwash our laundry, which is not too onerous if doing a little every couple of days and the clothes dry well in the spring/summer heat.

I have started to forage again. Unfortunately, we arrived on the river too late for the spinach and asparagus seasons, but I just caught the wild fennel and there is a lot of mint and rosemary planted around the towns. The grass near the beach at Sanlucar is overrun by mint and Martina says it makes great tea. I have collected oranges and lemons from the odd stray tree, neglected and not on anybody’s land. (A lot of land around the river is fenced off – people seem to like their oranges to rot on the ground rather than people being able to collect them). I am looking forward to the profusion of figs and plums ripening, and I hope the olives, almonds and grapes will follow.

Needless to say this is a mere drop in the ocean of the sort of  reduction in consumption that we all need to do. Even environmentally conscious people such as ourselves have only taken these steps because of our circumstances rather than out of a conscious drive.

But I am pleased by our efforts that benefit both the planet and our bank balance. Sailing (rather than motoring) nearly all the way here from the Mediteranean, even passing through the Straits of Gibraltar, against the normally prevailing current, pleased me a lot. I certainly felt good about not having an expensive fill up with diesel when we got here.

The important thing is that we don’t miss the conveniences, really we don’t! Life is simple and enjoyable. Life can be pretty good without a fridge, even in the summer heat. There’s a great river to swim in, great walks along the river bank, food for free, and healthy fresh air to breathe. I’d give up my fridge for that any day.

  1. Very interesting article Julian . I really enjoyed reading it and it somehow reminds me of growing up in Gilroy Avenue where we did not have a fridge until I was all grown up and neither did we own a washing machine . My mother , Kitty, did all the laundry using a washing board and lots of effort . Mind you we did have a lot less clothes in those days too . In many ways it was a much simpler life ( hard work for Kitty ) and probably better for us all and the planet .
    Happy sailing x

    • Hi Liz, Martina here. It’s amazing how much we have come to rely on fossil-fuelled conveniences in only one generation. You make an interesting point about having a lot less clothes. Because of lack of space aboard the boat, we have far fewer clothes than most people…but even so I think we still have too much. If you’re washing every few days, how many changes of clothes do you really need. The same goes for material stuff in general. Without so many things to care for – clothes, ornaments, this and that, we free up a lot of time and effort that would otherwise go in to the care of those things. And speaking of not having many clothes – Lily, Katie and I returned to the UK for an indefinite period with only one carry on case between us. I took great care planning the most appropriate combination of clothes for warm/cool/cold weather and for casual to semi-formal. We’re doing alright, and haven’t yet been kicked out of anywhere for being too scruffy!!!
