Skip to comments.France Will Dim Its Lights to Conserve Energy (pull the plug at 1am)

Under the new law, the interior lights of nonresidential buildings will have to be turned off an hour after the last worker leaves, and lights on building facades and in shop windows will have to be extinguished by 1 a.m.
Ms. Batho also presented the decree as a matter of public health. Artificial lighting can damage sleep patterns, she said, and also cause significant disruptions on ecosystems by changing communication between species, migrations, reproduction cycles or even the prey-predator relationships.

FYI - France makes 90% of their electricity by nuclear power...
Paris. “City of Lights”. LOL!
I realize that this is WAY BEYOND the comprehension level of New York Times reporters and editors, most of whom absolutely HATED MATH (just like public school teachers, by the way), but France is something like 80% Nuclear, the highest in the world (and without any major safety incidents, I might add).
Nuke power is base load. It simply CANNOT be turned down when load goes down, it takes days, if not weeks to lower the output of a nuke plant. So what happens? All that power that they STILL produce from their reactants ends up as heat and gets rejected locally. No different than light, as far as saving the world is concerned...it’s power. So, this is TOTALLY SYMBOLIC in that country - but hopefully, it won’t result in increased rapes due to cover of darkness, but I’m not optimistic.
It sure is a good thing they don’t have any crime there at night.
The lights are literally going out in Europe.
Figuratively, Islam has been shutting off their intellectual, cultural and religious lights for years.
France is a net exporter of power. All this will do is cause off peak electricity rates to go down for Spain. No less electricity will be consumed but the French will have to walk around in the dark.
It is true that Nuclear Power Plants are base load plants but it is not true that it takes days to lower out put. It can be lowered in a matter of minutes.
That being said Nuclear Power Plants are not good Load Following plants.
Varying power drastically over the course of a day makes it more difficult to control power.
On the bright side this will be a boon to the burglary business.
I won’t argue very hard with you...since you’re almost certainly right.
But answer this - does pulling back the rods actually “save energy” or do the reactants continue to decay anyway?
France can sell extra power to Germany as Germany phases out their nukes.
sorry for the quaduple post
Interesting about nukes.
I just read a story that cheap nat gas in the US will likely cause the shutdown of a lot of older nuke plants rather than upgrade them for continued use.
By reactants I assume you mean fission daughters which do decay and give off heat in the process.
The decay of fission daughter account for 5% or less of the reactors power out put.
Fuel can be conserved by reducing power. But as I said this is not the preferred way to operate a nuclear power plant. Besides complicating the operation of the plant raising and lowering reactor output places thermal stresses on the reactor vessel that can cause cracking in metal components and the reactor vessel itself.
Another problem with lowering reactor power to follow load is that it messes with the planned fuel burn up. Reactors are either on a 2 year fuel cycle or a 18 month fuel cycle. The burn plan has the plant running out of fuel in either the spring or fall when the electric grid is at its lowest demand. Mess with the burn out rate and the plant will shut down for refueling with unburned fuel. That means wasted money and higher cost for electricity for the consumer.
The best way to operate a nuclear power plant is to take the plant to 100% power and leave it there as much as possible.
If its worth saying once its worth saying four times.
Just joking. I have done it myself.
And I love looking at the stars myself. I wish I lived in a more rural area. The light pollution here is not terrible but it does wash out the Milky Way.
The sandrats, like all other rats, simply LOVE the dark.
(But only when living in civilized, non-muslim foreign countries.)
Shouldn’t be that tough, seems like most of France is pretty dim anyway.
Like I said, you OBVIOUSLY know this stuff better than me. So, thanks. My thoughts were in the right place, but I needed someone who knows the business to help me out.
Bottom line - it is silly for France, of all countries, to be doing this stunt.
I was not aware criminals can see in the dark any better than law-abiding persons.
So the burglars flashlights should reveal their presence.
As for turning off the lights in a room with no occupants that is something many were taught as children.
And pray tell,what reasonable purpose is served by leaving business signs on when there is no one around?
I don’t advocate getting rid of street or safety lighting,but designing the lights so the illumination goes where it is need and ONLY where it is wanted is a good thing.
Further I suspect the heating and air conditioning loads are an order of magnitude greater than the lights that will be turned off so ther actual impact on the power structure should be minimal.Lighting is usually taken to be about one-tenth or less of the total load.The businesses shutting off production machinery or restaraunt cookstoves is a bigger spike in usage.
Yes you were right. Got a few terms wrong but the concept right.
Last I know of France was about had an 80% nuclear power electric grid. So they may be able to run in the off peak hours with out backing the nukes down. They can coast down some coal or gas fired plants.
RightOnTheBorder says in #4 that France is a power exporter so that also gives them an out let to avoid lowering the nukes out put.
The law doesnt make sense to me on a number of levels (personal freedom first and formost) but it probably wont effect the operation of the nukes.
Thanks...we both agree that this is simply a silly stunt, but as you say, if they’re careful, they won’t put their power plants at risk.
More than anything else it is a gift to the environmental and animal rights lobbies.
Got to keep the coalition happy if you want to avoid those nasty no confidence votes away.
Will they have block wardens like in WW II, going around on bicycles to check everything.
You are correct no boiler likes any sudden change in operating temperature and pressure. The stresses are huge and can cause ruptured tubes, pipes and occasionally the change in EM fields can cause transformers to explode.
You seem to be well informed. The new gas turbine generators are the best for handling changes in load.
However the newest and most efficient are called Combined Cycle Gas Plant. They link a boiler on to the exhaust of a Gas Turbine Generator. That hot gas exhaust boils water that turns another steam turbine generator. These plants make pretty much the cheapest electric power available.
Under socialism, the city of light goes dark.
