.Energy Saving Myths – True or False?

 

With rising energy costs and growing concerns about environmental sustainability, people are constantly looking for ways to reduce their electricity usage. Unfortunately, not all energy-saving advice is based on facts. In fact, some of the most commonly shared tips are nothing more than myths that could actually increase energy consumption instead of lowering it.

Training organisations like Elec Training and online learning platforms such as www.elec.training are helping people understand what truly saves energy and what doesn’t. Knowing the difference is essential for reducing bills and protecting the environment.

In this article, we break down the most popular energy-saving myths and uncover whether they are true or false.

Myth 1: Leaving Lights On Uses Less Energy Than Switching Them On and Off

False

Many people believe that turning lights off and on uses more energy than leaving them running. This was partly true for some very old fluorescent tubes, but modern lighting—especially LED bulbs—uses very little energy when switching on.

Turning lights off whenever you leave a room is one of the simplest ways to save electricity.

The truth:

Switching off lights always saves energy with modern bulbs.

---

Myth 2: Phone Chargers Use Power Even When Not Charging

Partly True

A charger left in the socket does draw a tiny amount of electricity, even when not connected to your phone. This is known as “vampire energy” or “standby power.”

However, the amount is very small—typically less than £1 per year.

The truth:

Not a major cost, but still better to unplug for safety and savings.

---

Myth 3: Turning Up the Thermostat Heats Your Home Faster

False

Many homeowners think that setting the thermostat to a very high temperature heats the home more quickly. In reality, the heating system works at the same speed regardless of the thermostat setting. Turning it up only overheats the house and wastes energy.

The truth:

Set your thermostat to the temperature you actually need.

---

Myth 4: Electric Heaters Are Cheaper Than Central Heating

False for most homes

Portable electric heaters use a large amount of electricity. While they can be useful for heating a single small room temporarily, using them instead of central heating often costs more.

Central heating systems are generally more efficient for whole-home heating.

The truth:

Electric heaters are expensive to run and should be used sparingly.

---

Myth 5: Appliances Use No Energy When Turned Off

False

Many devices still consume energy when switched off—this is known as standby energy. TVs, microwaves, consoles, routers, and computers all draw small but continuous amounts of power unless fully unplugged.

The truth:

Use smart plugs or a power strip to cut standby consumption.

---

Myth 6: It’s Cheaper to Leave Heating On All Day

False

Some people think that keeping heating on continuously uses less energy than turning it on only when needed. This is incorrect. Maintaining constant heat means constant cost.

The most efficient way is to:

• Use a thermostat
  
  

• Set timers
  
  

• Heat your home only when needed
  
  

The truth:

Heating when required saves more energy.

---

Myth 7: Bigger Appliances Always Use More Energy

Not always true

Modern appliances are designed differently. A large A++ rated fridge may use less energy than a smaller old-fashioned fridge with poor efficiency.

Energy rating labels matter more than size.

The truth:

Always check energy ratings, not just dimensions.

---

Myth 8: Solar Panels Only Work in Hot Weather

False

Solar panels need sunlight—not heat—to generate power. They actually work more efficiently in cooler temperatures. Even on cloudy days, they still generate electricity, just at a reduced rate.

The truth:

Solar panels function year-round, even in winter.

---

Myth 9: Boiling Water in a Microwave Saves More Energy Than a Kettle

Sometimes true

Microwaves can be efficient for heating small quantities of water, but kettles are usually more efficient for larger amounts. However, overfilling the kettle wastes both water and energy.

The truth:

Use the right appliance for the right job and boil only the water you need.

---

Myth 10: Smart Meters Reduce Your Bills Automatically

False

Smart meters help you monitor usage—they do not reduce energy consumption by themselves. Savings only occur if you change your habits based on the data.

The truth:

Smart meters help you understand, not control, energy usage.

Expert Insight: Why Energy Myths Are Dangerous

There is a growing concern among electrical professionals that misinformation is spreading faster than real advice. From social media “life hacks” to outdated home tips, people often follow habits that don’t actually save energy.

During a recent electrical safety discussion,
“Charanjit Mannu, Director at Elec Training, warned”
that relying on unverified energy-saving myths can lead to unsafe practices and even higher bills. He highlighted the importance of educating the public with reliable, evidence-based advice rather than outdated or misleading information.

This reinforces why accurate training from organisations like Elec Training and educational platforms such as www.elec.training is so important.

How to Save Energy the Right Way

Instead of following myths, here are real, effective strategies:

✔ Use LED bulbs

They consume up to 80% less energy.

✔ Install a smart thermostat

It helps schedule and optimise heating.

✔ Insulate your home properly

Prevents heat loss and reduces heating costs.

✔ Avoid overfilling kettles

Boil only what you need.

✔ Maintain appliances

Clean filters on fridges, dryers, and heating systems.

✔ Unplug unused devices

Stops standby power drain.

✔ Use energy-efficient appliances

Look for A++ or A+++ labels.

These practical steps deliver real, measurable savings over time.

Conclusion

Energy-saving myths are everywhere, but blindly following them can lead to wasted money, increased consumption, and potential safety risks. By separating fact from fiction, homeowners can make better decisions and truly reduce their energy bills.

Thanks to guidance from organisations like Elec Training and online resources such as www.elec.training, the public can now access accurate information and avoid common pitfalls. As “Charanjit Mannu, Director at Elec Training, warned,” proper education is the key to preventing unsafe habits and ensuring energy is used efficiently and responsibly.

Understanding the truth behind energy-saving myths is not just wise—it’s essential.
