D’ailleurs on devrait obliger à équiper les voitures de lumières pour voir la route, et à les mettre la nuit, ça permettrait d’économiser en éclairage sur ce genre de voie publique !
Si c est des lampadaires solaires alors c est normal qu ils n éclairent que le jour
Ça devient pathologique.
Electricity in france comes mostly from N energy and demand is lower at night by a good third so they’re not gonna cause a blackout or be a major factor themselves. Imho the street lights aren’t an issue at all (i’m assuming they’re all lower consumption neon/krypto/hallogen gas tube or led by now).
Tho we gotta watch for gaz use in french industry i assume. It’s gonna make some corpos very unhappy.
Might i suggest they start covering in renewable and batteries to help if they have land and roofing, tbh. Every joule or m3 of gaz saved is of help. Maybe we can find financial solutions to make it viable for heavy industry.
Edit like steel and alu and chemistry are huuuge, massive users of energy for heating and melting materials or compounds, refining. Anything coming from additional electricity instead of (finite) heating gaz is a small win. Especially when you deal with gigawatts-equivalent use ranges.
A lamp post is likely 25 to 200w. A steel mill furnace :
> A mid-sized modern steelmaking furnace would have a [transformer](https://en.m.wikipedia.org/wiki/Transformer) rated about 60,000,000 volt-amperes (60 MVA), with a secondary voltage between 400 and 900 volts and a secondary current in excess of 44,000 amperes.
> To produce a ton of steel in an electric arc furnace requires approximately 400 [kilowatt-hours](https://en.m.wikipedia.org/wiki/Kilowatt-hour) (1.44 [gigajoules](https://en.m.wikipedia.org/wiki/Joule)) per [short ton](https://en.m.wikipedia.org/wiki/Short_ton) or about 440 kWh (1.6 GJ) per [tonne](https://en.m.wikipedia.org/wiki/Tonne); the theoretical minimum amount of energy required to melt a tonne of scrap steel is 300 kWh (1.09 GJ) (melting point 1,520 °C (2,768 °F)). Therefore, a 300-tonne, 300 MVA EAF will require approximately 132 MWh of energy to melt the steel, and a “power-on time” (the time that steel is being melted with an arc) of approximately 37 minutes.
So, lol at people pointing safety streets lights. It’s industrial use that needs reform. Tho we obviously need factories and industry even if we hate on corpos financially. Sufficient basic productivity levels are still needed for society. So backing up their use and material demands with low carbon in the interim maybe ?
Maybe moving some industries toward a night shift ? Even a 50% employee wage bonus to show on it is likely to be small in comparison to the energy use question.
