Time change and save electricity

[Christophe]

This is one more time we changed time tonight.

The reason (among others?) Of the introduction of this change of time summer / winter are the energy savings.

I have never really considered the question and actually I do not understand or is saving energy (except maybe with full and empty hours but it is purely financial and it is not what I call a saving of energy), is anyone among us serious about the issue?

The ideal would be to have 2 FR average consumption curves before and after the introduction of this time change (corrected by the growth of the demand of course ...).

Here is the debate ...

[Pyvesd]

from what I heard, we save the consumption of a city like Strasbourg or Montpellier (source RTE?), which would not be bad!

[Christophe]

Yes, but for what reasons (mathematically speaking)?

[Pyvesd]

lighting + heating period + in phase with the time of day?

I also very regularly asked this question. I really can not believe that the change of time has such an impact on our energy consumption but I'm wrong maybe ...

It's funny, but by doing some quick research I just realized that the Senate in 1996 had tried to question the change of time and had been rejected by the government of the time. Another funny detail is that ségolène had at the time been at the origin of a report a priori negative on the subject. But apart from that, it's difficult to find precise figures on the subject.

Speaking of time change, if you want it to be ok at home, you have to edit your profile and put GMT + 2 h

Personally, I have a lot of doubts about the energy saving issues!

In addition, the change of time has important repercussions on the biological rhythms and thus the health ...
It annoys me more and more (aging) but it exasperates me even more because I have children ... They are already experiencing the rhythms of their parents ...

I will not be surprised that the "security hole" is felt, to the great satisfaction of some ...

Yes a priori the time change, still save the annual consumption of a city like Bordeau

"It results from this joint reflection between the Ministry of Industry, EDF and the Environment and Energy Management Agency (ADEME) that the savings in electricity consumption are estimated at 1,2 billion euros. kilowatt-hours (9 (*)), or the annual consumption of a city like Bordeaux, stricto sensu.
'

From a report of the Senate: http://www.senat.fr/rap/r96-13/r96-130.html

This represents 0.5% of the electricity consumption, which must be a little less than the total production of wind energy in France (which must be around 2 billion kWh ..

In any case I got up an hour too late this morning and I was almost fluffy!
Citro do not you think you're a little too much on this one? Your health is deteriorated by many other things than this hour of shift!

[Christophe]

Yes a priori the time change, is still save the annual consumption of a city like Bordeau.

Certainly, but by what physical effect? That was the meaning of my question
