Shower Timers

One of the great luxuries in my life is a steamy hot shower. Between my exceptionally well-developed allergies and a lot of muscle and joint pain, more than one person has referred to the shower as my “safe place”. It’s somewhere that I can go and feel like a human being again. I take the kids in with me and wash them while I get myself sorted out, which reduces our family’s consumption since we share, but the showers had reached a length where it was time to acknowledge that my behaviour wasn’t sustainable.

The first thing I did was take note of how long I need to stay in the shower to get the health benefits. It actually isn’t long at all compared to how much time I was spending in there. The next thing I did was set a timer on my phone that would give me enough time to ease my muscles and sinuses, plus a couple of spare minutes to sort out the kids. I start the timer, get the water running, and when the alarm goes off we get out.

Our first few showers were a source of significant outrage for the girls. “But we just got in,” was protested loudly and with vigour. They made sure they blocked me from getting to the taps. They dragged their feet getting in with the hope that a slow start would make for extra time. Somehow they lost the ability to rinse themselves. I was fairly proud of their ingenuity.

Over the following weeks the protests slowly stopped. We got into the habit of having shorter showers. My girls started pointing out to me that the water needed to go off when the alarm started. Once their expectation for the length of a shower aligned with the timer, I started to casually reduce the time by a few seconds each week. We’re about half way now between what I’ve timed my body needs and where I started our timed showers.

When our latest gas bill arrived, I was genuinely shocked at the difference compared to last year. We only have three gas appliances in our home: our stove top, our gas central heating, and the hot water tank. Since we have solar hot water, and the gas is more of a booster than anything else, I expected this to be an insignificant change given the summer months. As you can see from our bill below, I was completely wrong.

48.71% decrease in gas usage

Because our usage is now so low, rounding means that I can’t see what our actual emissions were on the bill. Thanks to the calculator over at Carbon Neutral, I know that our carbon emissions for the two months were only 0.04 tonnes. That’s great, but what I’m really looking forward to now is seeing the drop on our next water bill.

Patch It

If you’re a woman above the age of puberty, one of the most soul destroying activities you can engage in is shopping for new jeans. You’re usually helped by another woman who has inexplicably managed to find a pair of jeans that fit her perfectly – probably because she works there and tries on every piece of new stock the second it arrives – who tells blatant lies such as “those look great on you” when you’ve got saggy bits at the back, bulging bits at the front, and camel toe that makes you question your future reproductive health.

Jeans with a ripIn light of the excitement that is jeans shopping, when my favourite pair of jeans developed an epic hole there was a bit of depressed whimpering. I tried to sew the rip closed, determined that they were still good, but it wasn’t going to work no matter how deeply steeped in denial I was. It was looking like the worst had come, and I was going to have to face the trauma that was jeans shopping.

Despair is a beautiful motivator, and as I was working on another sewing project I realised that I had a lot of small scraps that would normally go in the bin. I collected them all, set them aside and then, when I had a moment to concentrate, I looked at the scrap pieces and compared them to the hole in my jeans. One piece was a perfect fit.

Hole in jeans edged with zigzag stitch.I started the repair process by doing a zigzag stitch with my sewing machine around the edge of the hole. The zigzag stitch is great at locking in fraying threads and stopping that part from getting worse. It’s a simple way to make the fabric more stable without having the bulk of a hem. I don’t have a clue of this step is actually necessary when patching something, but I figured I could do all the sewing in less time than it would take me to turn on the modem to look it up online. I then did a zigzag stitch around the piece of fabric that I was planning to use for the patch, because it is necessary for that step.

Jeans with a patchOnce the jeans and the patch were ready, it was time to put them together. This was tricky because the patch is fairly narrow and the hole wasn’t in a straight line. I tried to pin all the way around in a single go, but the fabric was shifting and then I started stabbing myself. To get around both of those problems, I pinned and stitched along the bottom edge first because it was the easiest, straightest side. Once that was sewn on, I was then able to smooth the patch over the rest of the hole and make sure that everything lined up properly without odd ripples in the fabric.

When I triumphantly brandished my patched jeans at my family and asked for their opinion, my five year old immediately pointed out that I’ve sewn the patch on upside down. Sometimes I really hate it when my kids are right. The other observation was that the jeans are obviously patched and that this clearly isn’t in pursuit of a new fashion trend that I’m trying to set. To solve that problem I’m going to find a few other pieces of scrap fabric and sew them on in a random pattern, making sure I get parts where the denim is starting to look a bit delicate and also parts where the condition is fine.

Patching and mending clothes can seem a bit pointless, but from an environmental perspective it makes sense. Before trying to reduce our footprint I would have thrown these away and bought a new pair of jeans. I also would have thrown away the fabric that I used to patch them instead of finding another use for it. Clearly both of these will eventually end up in landfill when the jeans are past the point of patching, but if I can double the life of my jeans then I can significantly reduce my reliance on the fashion industry. That’s important, because the fashion industry currently uses an estimated 2% of our global carbon budget, and is projected to consume 26% by 2050 at the current rate of expansion, on top of all the other pollution it causes.

Roof Vents

As I write this today, it is currently 40.3°C outside, with a projected top of 42°C. For those unfamiliar with Australian slang, this is what we like to refer to as a scorcher. A hot wind is pounding the house, and I’m praying that the ice blocks I put in the chickens’ water this morning keeps them alive until the promised cool change sweeps in.

Welcome to summer in Melbourne, global warming style.

Despite the heat outside, inside the house is still relatively cool, and it is after 1pm. We have a new air conditioner, and I haven’t felt the need to turn it on. While I have no scientific data to back this up, I think the change is due to the roof vents we installed a few weeks ago.

Roof ventThe vents are a simple piece of technology, and because we bought a cheap version ($69 each) they are entirely wind powered. The basic idea is that the heat from the sun is warming the cavity between our tiled roof and the internal ceiling. As the space up there warms, heat starts penetrating our ceiling insulation and warms up the rooms below. By installing these roof vents, the heat trapped in the roof space is able to rise out of the roof and escape, rather than being forced into the area below.

A house the size of ours requires three of these vents, but we only installed two because we don’t want to block any roof space that might be needed for our future photovoltaic system. They work better on a house like ours because we have a pale green roof instead of the more popular black roofs that are sweeping the city, which means some of the heat is reflected instead of being absorbed.

In winter we might end up with the problem that we’re extracting heat that we would prefer to keep in the house. The nice thing about this installation is that it only took about an hour to set everything up, and we still have the missing roof tiles stacked out of the way. If they aren’t working for us during the cooler part of the year, we can simply take them down again and store them until next summer.

Our First Electricity Bill

We started working on reducing our carbon footprint in September this year, and we have now received our first electricity bill that has been generated entirely during this project. From when we moved into this house our usage had been consistently increasing, so we were all curious to see whether or not we had been able to change our behaviour and curb our consumption. The snapshot below is from that bill.

Our daily electricity use has dropped by 24.62% since last year.

We now pay an additional 5.10 c/kWh for 100% renewable energy, which only added $18.20 onto the bill. By managing to bring our consumption down so low, we were able to get our bill well under $200 for three months. At a time when Australians are suffering severe financial strain due to energy prices, this isn’t putting a significant financial burden on our family. The following table compares our summer usage to that of other households in the area.

Our electricity usage is significantly lower than comparable households.

As you can see, our four person household is using significantly less electricity than a one person household in our area. We’re really proud of ourselves for cutting back where we could and offsetting what we couldn’t reduce. At this point it would be easy to say that we’ve gone as far as we can and that now it’s time to sit back and relax, but that defeats the spirit of this challenge. We’re working on a lot of ideas that will reduce our household consumption even further – we still need to get through next winter in a house warmed by gas appliances – and I can’t wait to share with you next year some of the creative ideas that we’re testing.

Build A Garden

When I think of a suburban vegetable garden, I immediately think of a rectangle of land in the back yard. In my imagination it is a separate, utilitarian area that sacrifices aesthetics for practicality. It provides a lot of benefits through fresh, healthy food and reducing the family’s carbon footprint, but at the cost of a play space and relaxation area.

It has taken us over a year, but we’ve finally finished building the garden beds for our home. Our block is 632 square metres, and the vegetable garden takes up just over 100 square metres in addition to the fruit trees in the lawn. Instead of being that dedicated rectangle behind the house, our garden has become a key design element, something that enhances the available space.

We’ve been able to spread the vegetable garden out over the block because the house is positioned so that garden beds can wrap around it. There is a deep bed against the front wall in the north, beds along the fence in the east, and a series of beds in the west. On the south side the garden beds run along the fence where they aren’t shaded from the sun.

Our garden is an interesting space to move through. When we started I was worried that we would be removing most of the children’s play area. I always believed that children need large open spaces to run around and ride bikes. It turns out that if we leave the paths wide enough they can still do those things. Thanks to the wildlife attracted to our garden, they can also chase butterflies, hunt caterpillars, or watch bees collect pollen. Adults are also drawn to our garden, and almost everyone who visits for the first time comments on our use of space.

Vegetable garden growing corn and squash in a narrow passageway.The area that I am most pleased with is the narrow strip of land between the house and the eastern fence. In most homes this would be an unusable part of the garden, overgrown and considered too small to do anything with. It gets a lot of shade, and several people told me that it would be impossible to get anything to grow out there. It’s currently planted with corn and squash, all of which are doing well.

By having so much space available for food crops, we can potentially become self sufficient for certain types of vegetables. Growing everything that we need would completely eliminate our food miles for those vegetables. This aspiration is very much a work in progress, but we’re hopeful that we can learn how to make it work.

Killing Vampires

Garage door opener
I want to suck your power.

When I hear of vampire power, it doesn’t conjure up images of my appliances sucking the life blood out of our planet. Alas, that’s pretty much exactly what it means. Also known as standby power, this is the power used by your electrical devices when they are in standby mode. This wasted electricity doesn’t come cheap, costing Australians “a combined $860 million annually” and “almost 2.6 million tonnes of carbon dioxide emissions per year”.

Now, stabbing your appliances through the heart with a wooden stake might be fun, but it’s a challenge that could see you electrocuted if you aren’t careful. Happily, there is an easier way to tame these vampires so that you’re only using electricity when you’re, well, actually using electricity.

Introducing: the off switch at the wall.Power switch

This little switch is a nifty device that stops your devices from drawing electricity, and it was an astonishing discovery – for some people in this house – that once they are turned on you can actually turn them off again. It requires the Herculean effort of reaching over and flicking the switch so that the little red line isn’t showing. We’re lucky to have these switches in Australia, because poor unfortunates in other countries have to go to the trouble of actually pulling the plug out of the socket.

Once I discovered how much vampire power was costing us, I was on a mission to turn off everything at the wall. Microwave, computers, stereo, it was all powering down. The data from our smart meter shows that this has reduced our base hourly electricity consumption from 0.1kWh to 0.04kWh per hour. That might sound trivial, but over the course of a year this is a change of 525.6kWh or 0.48 tonnes of carbon emissions. Did I really need to have my exercise bike drawing power all the time? Since I didn’t even know it was plugged in until I checked the points, I suspect that I didn’t.

Turning things off at the wall has led to some unexpected changes. Our reliance on electronic devices for entertainment has dramatically reduced. The children are stuck playing with each other instead of watching the television because I’m too lazy to turn it on for them, and their relationship has dramatically improved. I tend to look things up on my mobile instead of powering up my energy guzzling PC. Even my partner has discovered that he doesn’t need perfect WiFi signal when it requires walking all the way into the next room and turning on our signal booster.

Germinating In The Greenhouse

In a sunny spot on our deck we have a small greenhouse. It takes up less than two square metres of space and is probably the best investment that we’ve made in our garden so far. We use it to grow most of our vegetables from seed, and the benefits are enormous:Greenhouse with seedlings

  • Food miles were a major area that needed improvement according to our carbon estimate, comprising almost half of our family’s emissions. A packet with hundreds of seeds weighs less than a single seedling in a nursery and considerably less than the final vegetable in the supermarket, so the energy required transporting them is drastically reduced.
  • Seeds planted in our greenhouse germinate much faster than they do in the garden. We recently tried to plant some zucchini outside the greenhouse, and after three weeks I assumed they had failed so I tried again inside the greenhouse. Our greenhouse seedlings were all growing strong before the first of the outside ones appeared.
  • Seedlings started in the greenhouse are protected from many more predators than ones out in the garden. Birds, snails and caterpillars don’t snack on my tender baby plants when they can’t get to them.
  • We can prolong the growing season for our vegetables by germinating them in the greenhouse where they are protected from frosts in early spring and we can keep the soil a bit warmer in early autumn. Last year we were able to get two pumpkin crops with early and late germination, and we didn’t need to buy pumpkins from the supermarket for almost six months.
  • Have you ever tried to grow a new plant, only to realise that you can’t tell the difference between the seedling and weeds? We don’t have a weed problem in the greenhouse, which has saved a lot of our vegetables from untimely deaths.
  • Because seedlings are so small and we are making use of vertical space in the greenhouse, we can literally germinate enough seedlings to completely fill our vegetable garden. We started germinating the lettuce to replace our broad beans before we finished harvesting them. Overlapping growing times like this means that we can sometimes get an additional crop from our garden each year. If we want to start growing something, but there isn’t room in the garden, then we just move it into a bigger pot so that it can keep growing until we’re ready to plant it outside.
  • You can get much more variety when you start with seeds than you can find in a nursery or supermarket. Our seed collection now has over 150 varieties of herbs and vegetables. We’re currently growing red spring onions, purple broccoli and multi-coloured corn.
  • Growing vegetables from seed has mentally completed the life cycle of plants for the children. They can put the seeds in the dirt and watch how they sprout, grow, fruit and then get turned into compost that feeds the next generation of plants.
  • If a packet of 75 seeds costs less than a single seedling, I don’t care much if I accidentally murder half of them.

Despite all of those advantages, the biggest one by far is financial. It doesn’t matter how much a vegetable or herb costs in the supermarket, because if I can pick up a packet of seeds for under $5 and grow kilos of food from them then we’re winning. A packet of seeds can last for years, which reduces the annual cost even further. This year I spent less than $150 on seeds, which will completely fill our garden and leave a lot left over for next year. To put that in perspective, that’s the same as our weekly budget for fresh fruit and vegetables. If we do as well this year as we did last year, we’ll get half of our meals from our garden.

Most of the materials that we use in our greenhouse are reused. I’ve got a large collection of punnets, seed trays and pots that have been donated by other people after they’ve gone shopping for plants. To keep everything moist and cut down on how much I need to water the seedlings, I put my pots and punnets into the plastic trays we get with meat from the supermarket. For the large seed trays, which don’t fit into the meat trays, I put one inside the other and use a plastic bag as a liner to hold the water.

Setting everything up for a season takes me an afternoon with the kids or an hour by myself, plus an hour going through my seeds and deciding what I want to buy for the coming year. Germinating our plants has quickly become quality time for the family, and we get much more out of it than I ever expected when we started.
