Hour change has no effect on your power consumption

On Sunday 27 October it’s that time again! That’s when we switch to winter time. At 3 in the morning we put the clocks back an hour: 3 a.m. becomes 2 a.m. So we get an extra hour in bed, the opposite of when we switch to summer time. But does this hour change affect your power consumption?

Origin of the hour change

The hour change in 1977 was intended to increase energy savings across Europe following the 1973 oil crisis.

How does this work in practice?

By making the hours of sunlight coincide more with the lifestyle of the population, optimum use is made of natural light and electric lighting is therefore needed for a shorter period of time.

The concept of ‘savings’

Although the hour change in 1977 led to significant energy savings, the real impact on consumption is now a thing of the past. The saving only took effect at the time of the changeover from normal time to summer time. If we compare the 2018 financial year with 2018, we see no savings at all.

Why don’t we go back to the normal time arrangements?

If we were to return to the previous time arrangements, switching from one system to another would lead to an increase in electricity consumption for artificial lighting.
