Busting Electricity Myths

In the world of electricity, there are prevalent myths that are passed around and are occurring far too often without any evidence that they are the truth. So, with this post, we are busting these common electricity myths and putting an end to them once and for all.

It’s Best to Leave Lights On

Powering on an Electric Light Uses More Electricity.

False! It is better to switch off lights even if one is leaving the room for a few seconds.

LED is More Expensive

HID, Incandescent or Fluorescent Technology is Cheaper

False! The one-time cost of an LED product may be higher. But it also lasts more than 10 times longer and uses 80% less energy than a bulb. Once you factor in the cost of 10 bulbs, electricity savings, and replacement costs, LEDs are much cheaper. In effect, it pays for itself in little over a year and generates considerable savings for the next 10 years.

Electricity Use on Appliance Start-Up Is Expensive

It Takes More Electricity to Power Some Appliances like Computers or a Cathode Ray Television than One Saves by Switching it off

False! The power surge when you power on an appliance is insignificant. In most appliances, there is no power surge. In a few appliances where there is a power surge, it lasts for only a fraction of a second. Even if a device were to use 4X its usual power consumption when powered on, you will break even in half a second or less!

Always Run A/C on the High Setting

It Takes Less Energy to Keep the AC running at a High Setting than to Switch it on and Cool the Building in the Evening

False! An air conditioner running all day at a higher setting will use a lot more electricity than what’s used by switching it on in the evening. Save money by cooling off your building at certain times, rather than all day.

Electricity Leakage is Not Expensive

Electricity Leakage Can Cause the Meter to Run and I Will End up Paying for Electricity I Didn’t Intend to Use

The answer to that one is simple. Switch off all equipment and unplug as many as possible. Now check if the meter is still running! Use the tips in our article ‘Why is my electricity bill so high?’ to determine if you are paying for electricity you didn’t use. And to find out how to reduce your electricity bills!

Use Incandescent / HID Bulbs Until They Burn out

False! The old bulbs are far less efficient than LED. Modern LED fixtures are more than 2-8 times more efficient! Every hour that the old incandescent bulb burns, it’s wasting your money. Replacing it with LED will start paying back from day one by reducing your electricity bill.

LED Bulbs are Not Dimmable

False! Manufacturers can create dimmable LED bulbs. It requires different electronics to do so. The most important thing to remember is that one should not try to dim a non-dimmable bulb. This puts undue stress on internal electronics. This will cause it to fail, and more than likely will void the manufacturer’s warranty. Likewise, be very careful with the dimmable switch that you use. The low amount of energy drawn by LEDs may place a burden on traditional dimmer switches. You might hear a hum from a dimmer switch which is a sign that the switch is struggling. They heat up as well, which could create a fire if turned on for extended periods. Always use certified dimmer switches meant for use with energy-efficient dimmable bulbs.

All LED Lamps Produce Bright, White Light

All LED Lighting is Harsh and Unappealing

False! The lights we have on this site have a warm tone. We ran some tests with consumers. They could not tell the difference between the incandescent and LED lighting fixtures.

Energy-efficient Climate Control Systems Will Cause My Electricity Usage to Come Down

Only partially true! The power bills will indeed come down. But if the HVAC systems are not installed properly, you will continue to lose money. Approximately, a third of the electricity used will compensate for improper installation. Similarly, if you use air conditioners and HID / Metal Halide bulbs – you end up paying twice. Once for heating the room (an HID bulb converts a lot of the electricity to heat!) and then to pump this heat out.

Energy Conservation Will Require That I Lower the Level of My Lifestyle

False! You can conserve energy by switching off lights when not in use, not using the standby mode in appliances, and setting the thermostat for the air conditioner a couple of degrees higher. It is also possible to reduce energy consumption through energy efficiency. Energy efficiency consists of replacing wasteful, inefficient appliances with modern energy-efficient ones. Replacing a 400-watt metal halide bulb with a 150-watt LED light will give you the same amount and quality of light, but it consumes a fraction of the electricity. You’re interested in the light and not in the heat that the bulb generates. There are more efficient ways of heating the room.

An Appliance That’s Turned off Consumes No Power

False! Some appliances continue to consume power even when they’re turned off. The problem is more acute in the standby mode. Air conditioners, for example, continue to consume power unless they’re unplugged. These appliances contribute to what’s called the ‘phantom load.’

I Don’t Need Efficient LED Bulbs

Dimming the Incandescent Bulb Will Help

False! For one, new LED devices are 8-9 times more efficient than incandescent. If you are willing to dim it that far – it would be better to use candles! On a more serious note – The relationship between power used and light emitted is not linear. When you dim incandescent bulbs, they become even more inefficient because more of the energy emitted by the incandescent is now in the infrared spectrum. This is why high-temperature incandescent bulbs have a higher efficiency of illumination. If you were to dim a dimmable LED light the results would be linear and you will save more power.

Frequently Switching Appliances On / Off Reduces Their Life

False! The notion is outdated. Scientists at the Lawrence Berkeley National Laboratory have shown computers last longer if they’re switched off. The on-off cycling was a problem with some earlier models of appliances. But new developments mean new appliances do not have shorter lives if they’re switched on and off.

Electric Heating is Very Energy Efficient

HID and Incandescent Bulbs are an Asset in Winter

False! This is a notion that many people have. Incandescent bulbs convert 95% of their energy into heat. That’s a tremendous efficiency ratio. The production of electricity from burning coal is an inefficient process. Of the total energy in coal only about a third is converted to electricity. And then there are losses in transmission and distribution. The bulb and the electric heater may be efficient, but the energy losses have occurred even before the electricity reached the socket! That is why direct combustion fuels like gas are best for heating purposes and are cheaper than electricity.

I Don’t Need to Turn off the Computer

The Screen Saver Will Help Reduce Electricity Consumption

False! The screen saver has no relation to the computer’s energy consumption. To save electricity, switch off computers or put them in hibernate/sleep mode. Or at the very least, switch off the monitor when the computer is not in use.

Leaving Computers in Sleep Mode Saves Energy

Only partially true! While sleep mode is alright if the computer’s left for a few minutes, even in sleep mode the computer draws 10 watts or more. Over extended periods this adds up to significant electricity wastage. If the computer is left unattended for long periods, it is best to turn it off.

Setting Thermostats to High Makes My Building Gets Heated Faster

The Reverse is Also True for Air Conditioning

False! Turning the thermostat high means the electric current will cut off after the thermostat reaches the higher temperature. It has no relation to the speed with which the temperature will rise (or fall if an air conditioner is set very low).

Energy Efficient Products are Expensive

False! Energy-efficient products are usually better designed and last longer. They also have better features and repay any cost difference through energy savings. Take a look at our lighting products. They’re offered at competitive prices and are efficient! Paybacks are quick. So any extra cost will be quickly recouped.
