Post your own sign to help remind people not to idle

On the tree of emission reduction possibilities, perhaps there is no lower hanging fruit than reducing unnecessary idling.

Natural Resources Canada estimates that if every Canadian driver reduced their idling by just three minutes a day, we would reduce emissions by 1.4 million tonnes a year – the equivalent of taking 320,000 cars off the road.  We would save 630 million litres of gas a year – over half a billion dollars worth.  Just by reducing idling, a simple habit change!

Here’s what you can do:

  • Idle less: limit idling to 30 seconds for the first start of the day and 10 seconds for subsequent starts, with a little commonsense leeway in cold weather
  • Skip drive-thrus: sadly, coffee shops and fast food joints have become idling ‘centres of inexcellence’
  • Post a sign: you can find simple, non-confrontational sign designs on the internet to post at your workplace, school or business! We did at our home, and it works – visitors and customers for our free-range eggs {shameless plug} no longer idle!  Just email me if you’d like a copy of our sign..



EnerGuide for Vehicles, the definitive guide to fuel economy

Few of us really know the fuel consumption of our vehicles. We may have a rough idea of how far we can travel on a $50 fillup, but that’s a pretty poor measure since fuel tanks vary in size and gas prices are always changing.

The real measure of a vehicle’s fuel economy is how many litres it consumes to go 100 kilometres, or its imperial system equivalent, how many miles you go on a gallon. And the very best place to get unbiased comparisons between vehicles is Natural Resources Canada’s fuel consumption ratings search tool. It’s a database that lists the official fuel economy of every make and model of vehicle sold in Canada since 1995. It allows you to find the best ones, or compare the models you’re considering. An invaluable tool for any vehicle buyer!

And – here’s a great two-minute video about other ways you can improve your fuel economy.

Go easy on the AC

July 7, 2015

Save on fuel by using air conditioning only when it’s really needed

It’s summer, and for many of us that means the air conditioner in our vehicles is always on. But consider this: air conditioning is second only to driving as the biggest load on an engine – it can increase your fuel consumption by up to 20%. Put another way, turning on the air conditioner is a lot like constantly hauling a trailer around.

So what to do?

  • Use fresh air when possible; sunroofs are awesome because they are quieter than windows
  • Get into the habit of turning off your AC when you park at the end of the day so it’s not automatically on in the morning when you least need it
  • Reserve AC only for really hot days, and use it intermittently; aim for comfortable, not cold
  • Park in the shade when you can

A well maintained vehicle saves fuel and money

True story: this week a friend of mine told me how his vehicle’s fuel economy declines each winter. (Not surprising – engines are less efficient in cold temperatures.) But he didn’t get the expected bounce back this spring, so he decided to take his car in for a check-up.

The diagnosis? His spark plugs were well past their best before date and were replaced.

The result? An instant 25% improvement in fuel economy.

Maybe it’s a good reminder to all of us to check our vehicle maintenance records and ensure everything’s up to date. Scheduled maintenance matters – for vehicle life, fuel savings and a reduced carbon footprint.

Three keys

The three most important things you can do to reduce your carbon footprint

If you’re like me, you might be feeling a bit overwhelmed with the complexities of climate change and our other environmental challenges. And, amid a flood of information, you might be wondering, “Really, what are the most important things I can do to make a difference?” In the spirit of last week’s Earth Day, here are my nominees:

  1. Drive less: every litre of gas we burn is one litre less we can burn if we wish to limit climate change. So walk, bike, take transit, carpool – anything to drive less.
  2. Strive to think ‘Reduce’, the most important of the three Rs, every time you flip a switch, turn a tap, touch a thermostat or operate an appliance.
  3. Contact your elected representatives via phone, mail or email to demand action, because climate-friendly laws and policies are absolutely essential to global solutions.

Should gas pump nozzles have labels on them?

One of the best ways to remind people to turn out lights is to have a sticker on the switch that says, “Please turn off the lights.” It’s a key principle of social marketing: place a message where your target audience sees it at the precise time they can make the choice you’re requesting. It’s the same reason blunt messages and graphic images are placed on cigarette packages.

Gasoline consumption generates emissions that are endangering our climate, so should there be warning messages on gas pump nozzles? The municipality of West Vancouver thinks so, and has passed a resolution suggesting that labels like the ones shown here should be placed on every gas pump in Canada.

Gas pump warnings

Maybe it’s not a bad idea. Every litre of gas we consume adds 2.4 KG greenhouse gas emissions to our atmosphere. If a reminder when we’re fuelling up reminds us to try to burn less fuel, that would be a good thing.

An interesting idea, and this week’s Green idea. More information here.

Ask your insurance company for a ‘black box’ for your car

Several weeks ago, my insurance company made an irresistible offer: if I agreed to install a tiny gadget in my car, they would reduce my car insurance premiums.

I agreed, and they sent me a little data monitoring ‘black box’. It took under a minute to install, and it sends info about my driving habits to my insurance company (specifically hard braking, sudden accelerations and total distance driven). In return, my premiums have dropped by 5%, and depending on how I drive, they may drop by as much as 25%. I get a weekly report card by email, which serves as a regular incentive to do better.

But I’m saving on gas too, because the driving habits the insurance company likes best – gentle starts and stops – also give me the best mileage. It’s well known that gentle driving can improve mileage by as much as 20%.

So – if you’d like to save on gas and insurance, contact your provider and ask for a ‘black box’ for your car. (Read a column with more detail on this here.)

Save with Low Rolling Resistance tires

If you’re in the market for new tires, look for Low Rolling Resistance (LRR) tires. Here’s why.

When you drive, your tires flex a bit at the point where they make contact with the road, and then relax back into shape while they are not contacting the road. The friction of this continuous flexing and relaxing is called Rolling Resistance. It creates heat in the tire (touch a tire after a trip and you’ll feel the warmth), and makes your engine work harder to turn the tire and move your vehicle – thus affecting fuel economy.

Today, many manufacturers offer Low Rolling Resistance (LRR) tires, which can improve fuel efficiency by 4%. That may not sound like much, but that can amount to $100 saved over the life of a tire – meaning the tires virtual pay for themselves!

Unfortunately, no standard or certification has yet emerged to identify LRR tires. (Goodyear and Canadian Tire have their own logos; Bridgestone has a brand and Michelin has a neat one-minute video demonstrating Low Rolling Resistance.) However, ask for them the next time you shop for tires – good for you, your wallet and the environment!

An efficiency Dream Team: block heaters and programmable timers

The depth of winter is upon us, and Baby it’s cold outside!  If your vehicle doesn’t have a block heater, perhaps it’s worth considering.  Block heaters:

  1. Improve fuel economy because your engine is semi-warm when you start it, and therefore runs more efficiently
  2. Reduce emissions because a semi-warm engine will burn fuel more cleanly and produce less toxic emissions like carbon monoxide, hydrocarbons and nitrous oxides
  3. Extend engine life because semi-warmed oil circulates better and lubricates an engine’s moving parts sooner than thick, cold oil
  4. Enable an engine to warm up quickly – meaning speedier defrosting and a warmer interior

Block heaters are standard equipment on some vehicles, or can usually be installed for a cost of $100-150.

Block heaters do use electricity – typically 400-450 watts, or as much as 30 compact fluorescent light bulbs.  If you plug in your car for 14 hours a night, that will cost $17-19 per month.  But since two hours are long enough for a block heater to warm most engines, one of the best investments you can make is an outdoor programmable timer that will turn your block heater on automatically while you’re still sleeping.  Investment?  About $25.  Savings? Over 80%.  Payback?  About 2 months.

Fuel-efficient driving techniques

Here are five driving techniques you can adopt to cut your fuel consumption (and emissions) by as much as 25%:

  • Accelerate gently (remember the ‘egg trick’ from a Green Ideas earlier this summer?  If not, you can find it here.)
  • Maintain a steady speed
  • Anticipate traffic around you to avoid the need for sudden stops and starts
  • Coast to decelerate: take advantage of your momentum and extend the life of your brakes too
  • Avoid high speeds: optimum fuel consumption happens between 50 and 80 KMH

You don’t have to spend a nickel to take advantage of these savings, just change a few driving habits.  For more details, visit the source of this information, Natural Resources Canada’s Office of Energy Efficiency.  Read an article with more eco-driving tips here.
