How to save energy this Christmas!

Wednesday, November 24, 2021

Here are a few simple changes you can introduce to help reduce your energy usage this Christmas, while still enjoying a home that is merry and bright!

Lighting and Decor

Upgrade your Christmas lights to LED

If you’ve been using the same set of lights to decorate your tree each year it might be time to upgrade to LED. The benefits are a brighter light, and they use 90% less electricity than traditional incandescent light bulbs. Saving you some pennies from your electricity bill this December.

LED lights range in price and can be picked up at Argos with 5% off if purchasing an e-voucher or reloadable card from Power NI Perks.

Switch to fibre optic decorations

Fibre optics is an emerging technology that uses glass or plastic threads to transmit light. By switching to fibre optic decorations, they use less energy than the traditional incandescent light bulbs, as only one bulb is needed to light the entire decoration. With the bonus of being shatterproof, shock-resistant, and cool to touch causing less risk of fire.

Fibre optic decoration can be picked up from different retailers such as B&Q and if purchasing an e-voucher or reloadable card get 4% off with Power NI Perks.

Decorate the garden with solar lighting

Your solar lights don’t need the sun to work as they can soak up the energy through the clouds. By using them to decorate your garden this Christmas they will cost you zero pounds in energy usage.

User a timer to manage your lights

A timer plug is a great way to automatically turn your Christmas lights on and off to dramatically cut down energy costs. Timers are also a great way to ensure your house is well-lit each evening which is great from a security perspective as people think you are always at home. The recommended timeframe is eight hours or less, so never return home to find you’ve left the lights on again!

Light the candles instead

At Christmas, we all love the smell of cinnamon, roasted chestnuts, or fresh pine. So instead of turning on the lamp why not light those scented candles in the living room, creating that lovely Christmas smell. With Power NI Perks you can earn 5% cashback if shopping online with Yankee Candle.


Turn down the heating by one degree

The Energy Saving Trust recommends that your room thermostat should be set to the lowest comfortable temperature, which is between 18-21oC. For every degree you increase the temperature, it will increase your heating bill by about 10%. So, wear that knitted jumper your Grandma made or those matching Christmas jumpers.

At night it’s recommended that you turn your thermostat lower between 15-20oC to help your body cool down and reach a level of deep, restorative sleep. By investing in a timer or programmer it allows you to control your heating and automatically adjusts the temperature at night or while you’re away.

 So, what is the recommended temperature for each room? Heating experts Vasco suggest:

  • Living room 19-22°C – As you spend most of your time in your living room wearing everyday clothes or pajamas, you don’t need it to be roasting.
  • Bathroom 23°C – Stepping out of a hot shower into a freezing bathroom is no fun for anyone, so you can achieve a higher temperature than the rest of your house with underfloor heating and a practical towel radiator.
  • Bedroom 15-20°C – This seems low, given the WHO’s warnings associated with temperatures. But remember almost all of the time you spend is under sheets, which provide their own warmth.

Light the fire

The true meaning of Christmas is giving, children, and family traditions such as a Christmas tree, drinking hot chocolate, or roasting chestnuts on an open fire, which is the most economical way to heat your home! By lighting your fireplace, you do not require any electricity, and some have the added benefit of connecting directly to the home heating system. Allowing you to save further on your energy bill.

Leave the oven door open after cooking

By leaving the oven door open after cooking the heat is released into the kitchen, providing warmth and heat this Christmas. Because the oven is already switched off, it won’t cost you any extra in your energy bill and it is heat that’s already been generated and paid for.


Whether you’re a master baker or a disaster in the kitchen, cooking more efficiently can help you to reduce energy bills and spend less time in the kitchen.

  • Put lids on your saucepans as the food will cook much quicker and requires less energy.
  • Cook in batches or several dishes at once.
  • Look through the oven glass instead of opening the door.
  • Cook extra on Christmas day so you just need to reheat for Boxing Day.
  • Don’t put hot food in the fridge or freezer as it has to work extra hard to cool down.
  • Turn off your hob or oven earlier as the temperature will stay the same for five minutes or more.


Swap the electronic devices for board games

Twister, Jenga, Monopoly… which one is your family’s favourite? Opt for the traditional board games this Christmas and turn off the TV and any new gadgets. By doing so you’re helping to reduce your electricity bill further and spend some quality time with the ones you love.

Don’t leave electronics on charge or standby

It can be easy to forget things and you would be amazed at how many people leave electronics charging when at full battery. We are all guilty of this and by leaving devices on charge, standby, or sleep mode they are still using electricity. Make sure to pull the plug on all electronic devices when charged and at night. This includes your TV, computer, games consoles, microwave … switch it all off.
