Here are some notes from Ron Kube and how he saved!
Lighting – saved 82%
He points to his dining room as a typical culprit. In one fixture, the couple had eight 100-watt incandescent bulbs, for a staggering total of 800 watts. By switching those eight bulbs to LEDs, Ron was able to slash the total to 112 watts without sacrificing a single lumen.
By the time Kube switched the rest of the bulbs, his home’s “biggest monster” had become a veritable pussycat. “In fact, we went from 340 kilowatt hours per month down to 70,” he says. “Lighting is no longer our biggest consumer.”
The good old beer fridge – saved 62%
Ron learned his old beer fridge was using more energy than his modern fridge and freezer combined.
With the big monster tamed, Ron was astonished to discover he had yet another energy-gobbling beast lurking in his basement. “We had an old beer fridge in the basement, and I found out it was taking between seven and 10 per cent of our monthly power—for a couple of bottles of beer and some wine.” Needless to say, he unplugged the fridge and relocated the beverages. The old beer fridge was using more electricity than his modern fridge and freezer combined.
Phantom power – saved 62%
During his detective work, Ron also learned about the concept of “phantom power.” Sometimes, even after you switch your devices off, they continue to draw significant amounts of electricity. In Ron’s house, the biggest culprit here was his entertainment system, which surprisingly was using seven per cent of the home’s electricity.
“Everything is supposedly turned off, but it was actually consuming about seven per cent of our monthly power.” Ron took all of the plugs and rerouted them through a simple power bar—with an on/off switch. “Now, off is off and everything is great.”
The slow cooking energy black hole – saved 50%
Here’s where Ron goes above and beyond. He also ran some cooking experiments. For example you want tea, but you fill up a kettle or pot with water. Heating all that water wastes a lot of energy–Ron starting filling the pot with the amount of water he needed for tea and he stuck a lid on the pot. This all saves energy. Ron even ran a cooking experiment where he pitted a slow cooker against a pressure cooker and a Thermos cooker. The slow cooker is an energy disaster using 2.5 times more energy than a pressure cooker and 4.3 times more energy than a very cool Thermos cooker.
All gain, no pain – saving 50% the easy way
With simple, inexpensive measures, Ron and Carole slashed their monthly electricity consumption by more than half—with virtually no impact on their lifestyle. “At the end of the day, we were able to reduce our power from the 12,000 kilowatt hours a year to 5,300 kilowatt hours a year.”
What is amazing about this is the Kubes slashed their electricity bill at a very low cost. Ron replaced 80 light bulbs with LEDs, unplugged the beer fridge, changed some cooking habits and put a smart power bar on his entertainment system.
Next – a solar powered electric car
Ron and Carole Kube have saved so much energy they now have enough extra solar electricity to power a Nissan Leaf for 20,000 km per year.
The Kube’s installed a nine kilowatt solar system when they were still using about 9,000 kilowatt hours a year for electricity.
Thanks to those simple energy efficiency measures the Kubes now have 4,000 kilowatt hours of surplus solar electricity from their solar system. Ron calculates that he could fuel a Nissan Leaf (electric car) for about 20,000 km a year with the surplus solar electricity.
If he uses this surplus solar electricity to power a car, Ron estimates the value of the electricity to him soars to 88 cents a kilowatt hour, since he would no longer need to buy gas for his car.
