Christmas is a time to enjoy: family gatherings, lights that fill the streets with magic, special meals, and unforgettable moments at home. But it’s also a season when energy consumption skyrockets. Christmas lights, heating, the kitchen running at full capacity, and appliances operating for longer hours all cause the electricity bill to rise just when we most want to enjoy ourselves without worries.
At Culmia, we know that an energy-efficient home is a more comfortable, sustainable, and economical home. That’s why we’ve put together this practical guide to help you save energy this Christmas without sacrificing the festive spirit, so you can enjoy the holidays with the peace of mind that comes from knowing your home is running responsibly and efficiently.

Magic can be efficient, too: plan your usage
The first step in reducing energy use is planning. During the Christmas season, we tend to turn on more lights, cook more, and spend more time at home. If you plan ahead, you can better manage spikes in energy use and avoid waste.
- Make a list of the appliances that use the most energy during this time of year: heating, oven, dishwasher, dryer, outdoor lights, television… and check how many hours you use them.
- Plan family meals so you can take advantage of the oven’s residual heat or cook several dishes at the same time.
- Avoid leaving appliances on “standby”: even if they seem to be turned off, they’re still using power. Turn them off completely or use power strips with a switch.
- Take advantage of natural light: During the day, open the curtains and blinds to let in the sunlight and warmth.
Planning doesn’t mean limiting Christmas; it means enjoying it wisely: every little thing adds up to help reduce expenses without sacrificing comfort.

Christmas Lights: Beauty and Savings Can Go Hand in Hand
Lights take center stage at Christmas, but they’re also one of the main sources of extra energy consumption. The good news is that there are ways to light up your home stylishly and efficiently.
Choose LED lights
LED light bulbs use up to 80% less energy than incandescent bulbs and last up to 10 times longer. They also produce less heat, making them safer and more sustainable.
If you’re still using traditional string lights, this year is the perfect time to replace them.
Use timers or smart plugs
Set the lights to turn on only during daylight hours. For example, between 6:00 p.m. and 11:00 p.m.
This way, you can maintain the festive atmosphere without having to keep the lights on all night.
Commitment to Solar Energy
Outdoor solar lights are an excellent choice for gardens, balconies, or patios. They charge during the day and turn on automatically at dusk, without any additional electricity costs.
Make the Most of Your Home’s Lighting
If you place the tree or the string lights near lamps or existing light sources, you can achieve a bright effect without having to turn on any additional lights.
A garden or living room that’s well lit with LEDs can look just as magical… and cost you half as much.

-
Heating: Comfort Without Waste
In many homes, heating accounts for more than 50% of energy consumption in the winter. With a few simple adjustments, you can enjoy a warm home without your bill skyrocketing.
- Ideal temperature: Keep the thermostat between 19 °C and 21 °C during the day and lower it to 17 °C at night. Each additional degree can increase energy consumption by 7%.
- Don’t block the radiators: Avoid placing furniture or curtains in front of them, as they hinder heat distribution.
- Ventilate strategically: Open the windows for just 5–10 minutes a day, preferably at noon, when the outside air is less cold.
- Use thick rugs and curtains: They retain heat and create a cozy atmosphere without having to turn up the thermostat.
- Close the doors to rooms that aren’t in use: This way, you can keep the heat where you really need it.
And if you have an efficient heating system—like the one found in many Culmia homes—take advantage of its programmable thermostat to adjust the temperature according to your schedule.

Efficient Kitchen for Large Banquets
At Christmas, the kitchen becomes the heart of the home. The oven, stovetop, dishwasher… they’re all working at full capacity. But even here, you can optimize energy use without sacrificing flavor or tradition.
- Plan your cooking: Make the most of every time you use the oven by cooking several dishes at once and using residual heat to finish baking.
- Don’t open the oven unnecessarily: every time you do, it loses up to 20% of the heat it has built up.
- Use lids when cooking in a pot or skillet: it reduces cooking time and energy consumption.
- Choose the microwave for reheating: it uses 70% less energy than a conventional oven.
- Fill the dishwasher before running it, and use eco or low-temperature cycles.
- Defrost food well in advance: Avoid using the microwave or hot water to defrost food.
A little organization and efficiency can significantly lower your energy bill— and best of all, without affecting your celebrations.

Appliances and Small Habits That Make a Difference
During the holidays, the pace at home changes: more get-togethers, more loads of laundry, more appliances running. But with a few simple steps, you can effortlessly keep your energy use under control.
- Turn off electronic devices (TVs, game consoles, computers) completely when they are not in use.
- Charge your phone only as much as necessary, and then unplug the charger.
- Use your washing machine and dishwasher during off-peak hours if your rate plan allows it.
- Adjust the temperature of the refrigerator and freezer (5 °C and -18 °C, respectively). Setting the temperature one degree lower increases energy consumption.
- Unplug electric decorations when you leave home for safety and to save money.
- Use power strips with a switch: they let you turn off the power to multiple devices at once.
These small changes, repeated every day, can add up to significant savings by the end of the month.

Energy Efficiency for the Whole Family: Leading by Example
Christmas is also the perfect time to teach children about sustainability. If you have kids at home, you can turn energy conservation into a game or a family challenge.
- Suggest a “Christmas Savings Challenge”: see who remembers to turn off the most lights or unplug the most appliances when leaving a room.
- Create decorations using recycled materials—pine cones, twigs, cardboard, paper…—to encourage creativity without increasing expenses.
- Explain in simple terms how the energy they save at home helps the planet and their own future.
- Celebrate your achievements: if the bill goes down or you manage to reach a goal, celebrate it as a family.
Turning saving into a shared value will make it natural to maintain these habits all year round.
-
Sustainable Decor Using Natural Materials
Saving energy isn’t just about reducing electricity consumption; it’s also about choosing sustainable and durable materials for home decor.
- Choose reusable or recycled decorations: avoid single-use plastic ones and opt for wood, glass, fabric, or metal.
- Decorate with natural elements: branches, dried leaves, pinecones, or seasonal flowers. In addition to being eco-friendly, they add warmth and authenticity.
- Use LED candles or rechargeable battery-powered candles: they achieve the same effect without any risk or ongoing expense.
- Incorporate live plants into your decor: a small natural potted fir tree or a wreath made of greenery that you can replant after the holidays.
Sustainability can also be synonymous with elegance and beauty, and every conscious choice contributes to a more responsible home.
-
Gifts and Responsible Consumption
Another aspect of holiday spending that also affects energy consumption and the environment is the way we buy and wrap gifts.
- Shop with a plan and buy locally: avoid unnecessary trips or expedited shipping, which generate more emissions.
- Choose sustainable gifts: locally sourced products, experiences, or useful items that promote responsible habits.
- Reuse wrapping paper or use fabric (furoshiki) to wrap gifts in a creative, waste-free way.
- Give the gift of savings: LED light bulbs, plants, energy-efficiency kits, or even smart thermostats can be gifts with lasting value.
This way, your Christmas spirit stays intact… but your environmental impact is reduced.
-
Track Your Usage: Technology That Helps You Save
Today, there are many tools that make it easy to monitor your energy consumption.
- Install a smart meter: it lets you see how much energy you’re using in real time and detect spikes in usage.
- Check your digital meter: Most companies offer apps or personal accounts where you can track your daily usage.
- Take a look at your habits: if you find that your heater or oven uses the most energy, you can prioritize energy-efficiency measures for those appliances.
The more you know about your energy consumption, the easier it will be to reduce it without sacrificing comfort.
