Quality In Life – Living Smarter…


Some energy efficiency is spending dollars to save pennies.

Our local electricity provider has been running “power smart” adds where strangers suddenly appear in your home or office cheering when you turn out the light as you leave the room, or as you turn off the powerbar to your computer.  The message is that you should be encouraged for such conservation.  I have in the past mindlessly accepted the idea behind these ads as valid, since I have for my adult life turned out the lights I’m not using, but recently I’m coming to question some of what I’m hearing.

Sometimes you might leave a light on for a feeling of security, or if you were to turn off the powerbar, your appliances might lose track of the date or time.  So there are valid reasons for leaving these on when you are not using them.

In TV-Land, all the switches and powerbars are easy to reach (although ugly lying on the desk etc).  In my life I don’t have VERY convenient powerbars, and am more likely to have to reach behind your appliances to find the power bars to turn them on and off (shock hazzard from loose plugs you can’t see clearly is so remote I won’t address that at all).  So the activity isn’t as free as it appears in the ads.  It costs me something.  Convenience (when the remote controls can’t make the appliance wake up), time (running around the house turning things off as I leave).  There is a cost to me.  The concept of power leaches or vampires, that suck a tiny amount of energy constantly has been a popular topic in the press in 2008.

Additionally there have been a number of ads about replacing my old inefficient refrigerator with a new energy smart refrigerator.  I’ve realized that I need to do some research on my own.  What is the cost and what is the benefit to me to the utility and to the environment.

Now I am the kind of guy who turns the VCR or TV off when I’m not actively using them. The lights all go out at night (with the exception of the 0.3Watt LED night lights in the halls).  I turn off lights I’m not using, but I installed the lights so they could be used.  They work for me, not the other way around.   So with a heart that wants to conserve and show my thankfulness through not wasting what I’ve been given, I wanted to know where we were wasting energy.  I purchased a $17 (blue planet?) meter from my local hardware store that can show the Amps, Watts and Volts being used by an appliance in real-time.  Additionally it can log the electricity usage, showing you the total Kilo Watt Hours (KWH) consumed by the appliance over a period of many days.  After you enter the cost of electricity ($0.072 / KWH here) into the meter, it can tell you the dollar cost of your appliance for the time it has been plugged in.  I started making discoveries:

computer / adsl modem / router / UPS / printer : $0.25 / day

Old inefficient refrigerator from the last decade: $0.40 / day

TV / VCR / video game / stereo: $0.10 / day

Laptop computer: $0.05 / day

Microwave:  $0.02 / day

So this causes me to think carefully about what I’m hearing and being told.  I’m being told to switch off the power bar for my TV etc, when the use of the devices is only $0.30 / day.  So conceivably I might save 1 or 2 cents there.  Hardly worth the time is it?  Could I pay you a penny to stop doing what you are doing and spend 10 seconds coming over here and flipping this switch?  If you were paid $20/hour, that is 5.5 cents per 10 seconds.  Now its true, if you have nothing else to do it wouldn’t hurt for you to spend your spare time doing this, but the benefit seems really really minute compared to the cost?  Why is your utility spending $100,000s on this advertising?

My understanding of the issue is that it comes down to capacity.  If they need to build another power plant that is exceedingly expensive, but if they can continue to sell power from the existing power plants, that is a much more reasonable proposition for them.  The issue is nothing if we are talking about you saving $0.01 of electricity for flipping off the power bar.  The issue is really only significant thanks to the power of multiplication.  If you can convince 5,000,000 people to save that much electricity, you just saved $50,000 of electricity per day.  So the impact to your utility is huge, but the savings for you as an individual user of electricity is essentially nothing.

Now how about that refrigerator.  $0.40 per day to keep my food from spoiling seems like a good deal to me.  I don’t have to go down into a cellar, I don’t have to drop my food down a well, or deal with bricks of ice, or food poisoning.  I think it is a bargain.  Through my study of the new energy efficient fridges on the market it appears that the new fridges would use half the electricity per day.  Over the course of a year that would save me $73 in electricity.  However a new fridge costs around $800 (depending on what you buy).  So it would take me 10 years for the fridge’s energy savings to pay for the fridge.  I don’t know about you, but with the quality of manufactured goods dropping, I’m not sure I would expect my new fridge to last me 10 years.  This old fridge on the other hand, continues to work and looks after the food just fine.  So the marketting says “buy a new energy smart fridge”.  To do that, somebody needs to manufacture the fridge with all its glass and plastic and metal and compressors and chemicals and foam.  Then they need to ship it across the country or around the world, advertise it, house it in a store, get it here, and dump my old fridge in a landfill or recycling depot (landfill that sells metal).  It seems to me that the most environmentally responsible thing I can do is to make my existing appliances last as long as I can. 

So suffice it to say that the meter has probably paid for itself in debunking “new appliance savings” and in giving me some peace of mind about the little power leaches plugged in at my house.

 I am happy to say that we enjoy the light provided by the current generation of Compact Flourescent light bulbs (CFL)s  Instead of 100W we use 50W of light over our sink.  Instead of 160W we use 44W in our bathroom. The list goes on of the places we have installed these.  The hallway light behind me, the lamp in the corner.  They aren’t the best light for all situations, but we know that the 33W we are using right now beats the 150W we would have had otherwise.  To my mind this is a very smart energy saving, because apart from purchasing the bulbs initially, there is no incremental cost to turning on a CFL over a standard incandescent light.  It just saves me money and saves us all power without inconveniencing me or introducing an additional cost.

We need to take a very strong stand against “GreenWash” in all its forms.  Keep your brain engaged as you are urged to do this or to do that to save the planet.  Among the genuinely good information there is certainly hype that is designed to pad someone elses wallet at the expense of your own.



Transcanada Highway Lower Mainland

The Trans-Canada highway in the lower mainland of BC South of the Fraser river has remained virtually unchanged since the 1960s. As you drive over the 40 year old overpasses, you can see the date of their construction stamped in the concrete. Each overpass following the same 2 lane bidirectional model with few exceptions. In recent years three of these interchanges have been upgraded or replaced. First the 208th street overpass (+2 lanes) in Langley was built to relieve pressure on 200th street, then 200th street (+2 lanes), Vedder Rd (+2 lanes) in Chilliwack, and Mt Lehman (+5 lanes) in Abbotsford. The total increase in lanes crossing the freeway since 1960 appears to be 11 for a distance spanning approximately 85KM. This is in an area where the total number of lanes crossing is now 66 lanes increasing from the 55 provided in the 1960s.

Now the Lower Mainland and Victoria areas of BC account for 9% of the population of Canada. In 1961 the population of BC was 1,629,082 just 20 years earlier it had been half of that. 30 years later it had doubled to 3.2 Million in 1991. At that time there had been no increase in lanes, with the 208th overpass being added some time in the 1990s. In 2006 the population of BC was 4,1 Million. That population increased 2.5 times from 1961 to 2006. In 2006, the combined population of the area south of the Fraser in the lower mainland including Chilliwack, Abbotsford, the Langleys and Surrey was 692,000. We can infer a similar increase in the population of the lower mainland that is accurate enough for this discussion.

The population increases to 250% of 1960 levels, but the overpasses increase of 20% of 1960 levels. Clearly the capacity enjoyed in the 1960s is not enjoyed today and the Federal and Provincial Governments have not paid close attention to maintaining our transportation network.

The 200th street fiasco got delayed for years (6 years?) because as I understand it, the provincial government tried to avoid paying cash for the interchange, and instead managed to trade adjacent land and favourable zoning to the developers. This delay affected thousands of area residents who were forced to queue for years to cross the freeway. Nowhere in the cost savings, was the inconvenience to citizens measured. Eventually the existing 2 lanes crossing the freeway were torn down and replaced with other lanes crossing the freeway, and a big box shopping centre was installed in every adjacent piece of property to the detriment of the traffic.

Now to area residents, it seems that when the Golden Ears Bridge comes in 2009, that the 200th st interchange with its multitudes of traffic lights and single lanes will be completely overwhelmed.  It has been obvious for the last 10 years or so that the only logical location (the empty place in the river where the roads have been aligning) for the Maple Ridge Langley bridge to exist is at 201st street near the water treatment plant on the Fraser river. However, area traffic has been queuing excessively between freeway and big box retail area and industrial area for 15 years. In 2009 when the bridge traffic joins the freeway at 200th we’ll see what happens. Currently, in the mornings, Westbound commuters have found traffic trying to exit Northbound at 200th from the Freeway.  These vehicles are often lined up for 1/2 a mile along the side of the freeway.  Naturally some of these vehicles stick into the Freeway lanes, creating an extreme traffic hazard for the 100 KM/hour traffic.  The exit needs to have double the capacity to carry traffic from Westbound Freeway to North and Southbound 200th.  The Lights at the interchange at 88th North of the freeway need to function so they do not impede the flow of traffic off of the freeway.  Sensors in the roadway on the exit ramp should be linked to these lights, such that when there is a backup of traffic attempting to leave the freeway, the light stays green allowing the traffic to continue to flow North across 88th and off the the Freeway.  It is much more important that a traffic light not impede the flow of the freeway, than that cars are allowed to get onto the freeway. It comes back to our methods for handling intersections and our fascination with traffic lights despite their implicit need to stop “some” traffic at all times. So 200th looks like too little too late, and time will tell us this year whether the engineers and architects planned well or planned poorly

Apart from inadequate overpasses to get local populations across the freeways, truck traffic, has not been given fair treatment on our freeway.  Nowhere except at the East bound truck scales (near 160th) do we find a third lane provided for trucks to gain speed as they climb a hill.  [EDIT: since I started drafting this article, a climbing lane has been added Westbound at Mt-Lehman THANKS]. This “feature is missing in many locations including but not limited to:  200th to 216, 232 to 208,  232 to 264, Mt Lehman, Sumas way to Macallum Road and Peardonville to MtLehman. Since our society seems to have embraced freight bearing trucks and largely dispensed with rail, it is strange to see that government is not adequately supporting the needs of trucks on our roads. Clearly there is much to be said about how freight trucks on our roads interact with other drivers, but that will have to wait for another article.

Interchanges, trucks, another deficiency of the Transcanada highway in the lower mainland that bears mentioning is that we do not find reasonable on-ramps. There does not seem to be a standard for a safe on-ramp despite the pretty illustrations in the Province’s driver’s handbook.  Almost every freeway interchange is designed uniquely and differently from other interchanges. In some cases these on-ramps and off-ramps, and these are becoming increasingly dangerous as the level of traffic congestion increases.  One feature that we sometimes see on the freeways in other cities which is absent in our own is the feature of a lane that links the on-ramp at one interchange with the off-ramp at the next.  By way of example, in Abbotsford Westbound between Sumas and Macallum exits, there is a relatively short distance of about 1 km where such a lane would allow traffic to merge less suddenly, allow traffic leaving the freeway to get out of the flow of traffic earlier, would have a limited cost and would reduce congestion by smoothing the flow of traffic onto and off of the freeway while increasing capacity between interchanges.

As fragile and full as our freeway traffic may be here in the lower mainland on the transcanada highway, another factor that contributes to the overall situation, is that we allow overloading the freeway with spikes of traffic. For example at 232 Eastbound in the afternoon rush, traffic coming in on the on ramp is equal in volume and speed to the traffic in the fast-lane.  The slow-lane has emptied itself of cars at the other side of the interchange as everyone preemptively avoids the merging traffic. Imagine with me, that if the freeway is at 100% capacity before the merge, then it is at 150% after the cars merge on.  They come in bunches.  The bunches overwhelm the freeway’s ability to smoothly absorb the traffic.  There is a bunch and then nothing and then another bunch.  Bunches are equal to the density of traffic in the fastlane.  Other jurisdictions address these spikes in traffic volume by leveling or smoothing the traffic admitted to the freeway. Metering the on-ramp would lower the density of the traffic coming on to the freeway, spreading it out and allowing for a responsible and sustainable merge into the slow-lane from the on-ramp.  This should better allow the freeway to retain its flow (its speed).  When the speed of the freeway drops to a crawl the people who just merged on, can force their way across to the fastlane, further disrupting the flow of traffic. Ideally where there are merge points, there would be some method to reduce lane switching to reduce the “turbulence” created by merging traffic.

If that isn’t bad enough, some commuters, knowing about this issue, choose to exit the freeway and drive in the decelleration lane only to re-enter the freeway at the point of congestion.  They effectively drive around all of the patient drivers who are slowing prior to the congestion, but they compound the problem by further disrupting the flow of traffic at the merge point, perpetuating the situation they “avoided”.

Congestion on this highway is such that it took me 37KM from the 160th exit in Surrey to exit 87 in Abbotsford BC to catch up with a semitrailer hauling large sections of steel pipe.  With uphill sections and that kind of weight, you can appreciate he wouldn’t be the fastest vehicle.   It goes to show you how inefficiently our freeway is working, when a capable vehicle cannot pass a lumbering vehicle , much less catch sight of it. This suggests the need to pro-actively increase the number of lanes to maintain traffic capacity.

I have hear the argument time and time again that if we build better roads, more people will drive their cars. While it is probably true that people who already drive their cars will drive further because they will get there in the same or less time than they currently do. We are currently experiencing a dramatic increase in the number of cars on the road despite no new roads being built. The argument would be fair if there was an alternative that was cost effective, reasonable and efficient. Unlike much of Europe and many major US centers, we do not have an effective rail transportation system unless you live and work within a 1/2 mile of the sky train. Bus service is “spotty” at best especially if you live outside of the Vancouver core. Traveling from Fleetwood in Surrey to BCIT in Burnaby by bus and skytrain takes 1 hour longer per day than making the same trip in a car on the freeway. How a 45 minute trip could take 30 minutes longer by using transit (1:15) highlights the situation that the lower mainland’s transit is in many cases 60% less effective at moving people. So we must have our roads alongside other solutions. If we neglect the roads we neglect the citizens who must travel them to hospitals, to work, to return home, we neglect the freight corridors that bring food to the supermarket etc.

We need to think twice about only doing what is “cost effective” and need to start doing what is “traffic effective”. The whole point of building a transportation infrastructure is not to “save money”, the point is to provide transportation. It is expected to be costly because it is a long term investment which yields continuing dividends in terms that may never appear on the bottom line. Reduced pollution, shorter commute times, higher efficiency, improved commerce, improved health through lowered stress, better safety resulting in fewer injuries and medical costs. It is like the cost of minting a penny. some people object to a penny costing more than 1 cent to mint, thinking that somehow there is a loss, but in reality, a penny allows for commerce, and will be used and re-used many hundreds of times in its lifetime creating a value that far outstrips the cost of minting it.



Saving Water

Some simple tips for water conservation.

  • Wash your hands with cold water, this saves waiting for warm water to arrive at the faucet
  • Turn off the tap while you are soaping up your hands while washing.
  • If you prefer chilled water, keep a jug of water in the fridge so you don’t have to run your tap while waiting for cool water.
  • Use a bucket to wash your car, using the hose only for rinsing.
  • Use a container (like a 4Litre milk jug) filled with water to water plants by poking a small pin hole in the bottom, rather than running a house continually.
  • Fill kitchen pots with cold water and allow stove to heat. (this is still somewhat up for debate in terms of the energy used)
  • Water lawn in evening or morning when there is no direct sun to evaporate your water
  • Do not water lawn daily, water once per week allowing a good soaking, do not allow water to fall on hard surfaces, or to drain from lawn to hard surfaces.
  • Allow your lawn to grow longer in summer (3-4 inches) so it can stay healthy in dry summer conditions.
  • Consider using a “rain barrel” to store water (rain water is especially good for plants) rather than allowing it to get drained off via your house’s drainage system.
  • Don’t allow your sprinkler to water the driveway, sidewalk, or street. This water evaporates quickly so it is wasted. Also stop watering if your lawn or garden starts allowing water to run out of it onto the street. it means your land is saturated and should not be watered further.
  • Set a timer to remember to turn off your sprinkler.
  • Turn off your hose at the faucet on your house, rather than leaving the hose under pressure, where it can leak through couplings or nozzles which are rarely 100% water tight.
  • Turn off the tap while you are brushing your teeth.
  • Skip a bath or shower.. I’m serious, chances are there is one day a week when you don’t have to smell like a rose. You are getting up, going to chop firewood, and then heading out for a hike. Instead of showering first thing in the morning, save it for evening before you go to bed. When you rise in the morning, you will have just barely had your shower the night before and you can avoid wasting multi-gallons of clean water. Note this won’t always work, and some people need their showers more than others.
  • Put a brick in your toilet tank to reduce the amount of water used per flush.
  • Fix tap leaks by replacing washers or cartridges. http://www.slowtheflow.com/repairing-faucet-leaks.html It’s easy unless you have a major plumbing problems.
  • Fix toilet leaks http://www.slowtheflow.com/repairing-toilet-leaks.html (even silent ones you don’t know you have) Remember the water where you are doing the repair is the fresh water that comes in from your water supply. Relatively speaking it is much cleaner to work on that end.  They provide a handy (albeit general) pdf brochure for fixing toilet leaks.
  • Choose a property with trees that shade your yard, providing better conservation of water.
