First of all, The Guardian reports that some of the largest countries are looking to reduce energy consumption from their public tourist attractions, such as France.

Country officials announced that they will switch off the lights that illuminate the Eiffel Tower an hour earlier, a measure that officials say should reduce energy consumption by 4%.

France's government also encourages every individual and industry member to reduce energy usage where possible.

Supermarket chains Carrefour and LeClerc, as well as luxury goods group LVMH, who owns brands such as Givenchy, Christian Dior and Tiffany, have been told to shut the lights off three hours earlier.

Home users have also been instructed to drop the ambient temperature by a few degrees Celsius and to use energy-intensive appliances during off-peak hours.

Lowering the heating is a measure that will be applied in public buildings as well as sport complexes, which are also instructed to used lower-energy LED lights.

During summer, shops that used air conditioning were also imposed to keep their doors closed or they risked a 750 euro fine, according to Euronews.green.

Spain is another country that applies the "lower temperature" rule in public buildings, which are to be heated no higher than 19 Celsius.

While households are not told to do the same officially, they are encouraged to follow the same example if they can.

Shops are also to shut off the lighting for their display after 10 PM and air-conditioning units or heating systems must have a door sensor so that they can be turned off to avoid energy waste.

In Germany, officials agreed to turn on illumination on public buildings and public monuments, such as the Brandenburg Gate, between 4 and 10 PM, except during cultural festivals.

Advertising billboards will also follow suit in an effort to reduce energy usage.

While the annual light show festival happened recently in Berlin, organizers said they were able to reduce energy consumption by 75% compared to last year.

Public administration offices are to be heated to a maximum of 19 Celsius, similar to measures taken in other countries, while public pools will also see their temperatures dropped.

Other countries started taking measures during the summer of 2022 to reduce their energy consumption, such as Greece, which imposed a minimum limit for the air-conditioner temperature of 27 degrees Celsius in public buildings.
