In 2020, households accounted for 27% of all energy consumption in the EU. In Luxembourg, the vast majority of this energy usage went on keeping homes warm.

While space heating accounted for 81% of energy usage in the Grand Duchy's homes, heating up water accounted for a further 7.5%. Thus, in total around 88% of energy used in the home was for heating.

Just 0.5% of energy usage went on home cooling, which may come as a surprise during the current heatwave. Meanwhile, 8% of energy use went to lighting and electrical appliances. The remainder, around 3%, went on cooking.

Compared to the EU average, substantially more energy went on space heating in Luxembourg than elsewhere. 62.8% of energy consumption in the EU in 2020 went on space heating, with a further 15.1% on water heating. A greater proportion went on lighting and appliances and cooking, however.


Across the EU, 31.7% of household energy consumption was covered by natural gas, with electricity (generated by various means, including solar and wind) accounting for 24.8%. Renewables used directly by households, such as solid biofuels and ambient heat from heat pumps, accounted for 20.3%, followed by oil and petroleum products (12.3%), derived heat (8.2%) and coal products (2.7%).

Five tips for saving on your heating bill

Given soaring energy prices in Luxembourg, here's some tips to cut down on your heating bill when the cold weather returns:

1. Lower the temperature of your thermostat by 1 degree Celsius. Each degree lower could save you as much as 2% on your heating bill.

2. Get yourself a programmable thermostat. This could be a smart thermostat like the Nest, but any which allow you to schedule when your heating comes on and off will do the job.

3. If your radiators don't already have adjustable valves, get them installed. This lets you override the thermostat and set specific temperatures for individual rooms. Not using a room much? Turn the valve down and save yourself some money.

4. When the sun is shining and the weather outside is cold, open up your blinds or curtains and let the sun heat up your home.

5. Plug any gaps. Extra insulation is always a good idea - both for keeping the house warmer during the winter and cooler during the summer.
