Here’s an interesting fact from Scientific American’s recently published Earth 3.0 magazine.
“Running hot water at a sink for five minutes uses the same amount of energy as burning a 60-watt lightbulb for 14 hours.”
I did a test at home using an electricity monitor I bought called The Owl and found that after running the hot tap for about 20 seconds, the Owl registered an increase in my household electricity usage of around 1,800 watts for 2 minutes. That means my electric geyser had switched on for 2 minutes.
Save electricity and lower your carbon footprint (electricity in South Africa is mostly generated by carbon-belching coal-fired power stations) by being mindful of the amount of hot water you use. Make sure your hot taps are switched off properly and don’t use hot water for things like washing your hands or rinsing dishes when cold water will do the job just as well.
