When it comes to energy use at home, misinformation is everywhere. Small habits, misunderstood appliances, and well-meaning advice can quietly drive up your bills without you ever noticing.
Let’s clear the fog. Here are six of the most common energy myths, and what actually makes a difference to your usage.
Myth 1: “Phone chargers left plugged in don’t use any power”
Reality: They do just very, very little.
A phone charger left plugged in without a device still draws electricity. It’s known as vampire power (or standby power). One charger won’t move the needle on your bill, but dozens of plugged-in devices across your home add up over time.
Why it matters:
Unplugging chargers won’t slash your bill overnight, but it’s an easy habit that reduces waste and wasted energy is still wasted money.
Myth 2: “Turning the heating up high warms the house faster”
Reality: Your heating doesn’t sprint, it cruises.
Cranking the thermostat to max won’t heat your home any quicker. Your system works at the same speed regardless; it’ll just stay on longer and overshoot the temperature you actually want.
Why it matters:
Set your heating to a comfortable temperature and let it get there steadily. You’ll avoid overheating and unnecessary energy use.
Myth 3: “Boiling more water is fine, the kettles run on time, not quantity”
Reality: More water = more energy.
Kettles use energy to heat water. The more water you boil, the more electricity you use. Simple as that.
Why it matters:
Only boiling what you need is one of the quickest, no-effort ways to cut everyday electricity use.
Myth 4: “Appliances in standby mode are basically off”
Reality: Standby still means “on enough to cost you.”
TVs, game consoles, coffee machines, and sound systems all draw power while on standby. Across a year, this “background drain” can account for a noticeable chunk of household electricity use.
Why it matters:
Using a power strip or fully switching off appliances helps stop paying for energy you’re not actually using.
Myth 5: “Cold washes don’t clean your clothes”
Reality: Modern detergents are designed for cold water.
Most everyday laundry, that is, lightly soiled clothes, sportswear, and regular loads, comes out just as clean at 20–30°C.
Why it matters:
Heating water is the most energy-hungry part of washing clothes. Cold washes save energy, reduce bills, and are gentler on fabrics.
Myth 6: “Smart meters raise your bills”
Reality: They measure. They don’t misbehave.
Smart meters don’t increase your energy use or change your prices. They simply give accurate, real-time readings instead of estimates.
Why it matters:
When you can see what you’re using, you’re better equipped to control it. Knowledge doesn’t cost more, it helps you waste less.
The Bigger Picture: Small Myths, Real Money
No single habit will magically halve your bill. But stacked together, small changes based on real information can make a meaningful difference, especially when energy costs are under pressure.
Understanding how energy actually works puts control back where it belongs: with you.
