Time change: savings of 300 million but with 95% of the population against

This weekend, between the early hours of Saturday and Sunday, the winter time change will take place, 3:00 will be 2:00.

This Saturday morning the time changes.

We entered the winter schedule and for almost half a century, Europe has changed its time. As of this weekend, between the early hours of Saturday and Sunday, the winter time change will take place, at 3:00 it will be 2:00. A change that has always been attributed to energy saving, but that 95% of the Spanish population is against.

Earn Energy, an independent light trading company, analyzes the evolution of the winter time change from its origins to now and whether the new scenario of light hourly sections will influence bill savings.


The origins of this practice date back to 1916 and it was in full World War I when Germany first decided to set the clock to save fuel. After in 1973, coinciding with the oil crisis, the time change began to be officially applied in several countries, including Spain.

The need to save energy resources is what all these historical milestones have in common and the reason why the time is changed in winter.

In Spain, the time change seeks to adjust the working day with natural light to reduce energy consumption. At dawn earlier, you can do without turning on the lights when you get up in the morning or during the first hours of work.

In addition, the clock is usually adjusted on weekends and at dawn to minimize the impact on the work and personal environment.

Will it be the last time change?

This change continues to generate controversy with supporters and detractors and a debate that is repeated year after year.

In 2018 the European Commission carried out a citizen survey on the time change that resulted in a 84% of participants in favor of eliminating time changes and opting for a fixed schedule throughout the year. In the case of the Spanish, 95% of those surveyed chose to suppress the time change.

Since then, Europe has proposed setting a single schedule for member countries, but the decision-making was delayed by the pandemic, so it is still on the air today.

Why does the time change in winter?

This change seeks to adjust the hours of sunshine with the working day to reduce energy consumption and therefore the environmental impact. At dawn earlier it is possible to reduce the use of artificial light when we get up and during the first hours of work.

But how much savings are we talking about? The Institute for Energy Diversification and Saving (IDAE) estimates an energy saving of a 5% with this schedule, which with the sum of all households, services sector and industries translates into about 300 million euros.

With the new time slots in the electricity bill, there are many who wonder what will happen to the electricity time slots and the time change but, since Earn EnergyThey explain that they will remain as they have been until now.

“With the time change, we will benefit from more hours of sunshine in the morning, when the consumption of light is higher, so we can do without turning on the lights,” says Antonio Picazo, CEO of the company.

In turn, the company recalls that it must be taken into account that in winter the consumption of electricity and gas tends to increase due to the use of heating. Also, it emphasizes the importance of maintaining responsible consumption habits to prevent the bill from skyrocketing and comparing between the different offers to choose the cheapest rate that allows you to continue saving whatever time it is.
