According to a Purdue University Study dark mode can save 3 to 9% of your battery if you're on auto brightness. Let's say your average phone uses 15Wh per day (5.475 kWh per year). Let's say 5 billion people use smartphones. That's around 30 TWh for total yearly smartphone consumption.
So if everyone was using dark mode, it could save around 0.8 to 2.5 TWh a year in the best case scenario. But that is if everything on your phone was dark mode. Not sure how much time people spend browsing websites percentually.
That's around 0.1 to 2.7 times the daily electric energy production of all nuclear power plants.
The world electricity production is around 23000 TWh per year, so you could save around 0.0036% to 0.01% of yearly energy consumption by switching everyone to dark mode.
Such impactful, much environment, wow
Fuck Nestlé, but technically they are right - it saves a little bit of energy and that's not a bad thing.
Yes, it's a drop in the ocean compared to the amount of energy we produce and no doubt there's better ways to save energy but heck, I'm down for doing the little things too.
Besides, it might encourage others to offer dark mode and that's no bad thing.
Again, I reiterate my opening statement: fuck Nestlé.
While I think it's nice that more people care about the environment, I wish that that same attention was proportially distrubuted amongst the issues causing the most damage instead of inconsequential shit like this.
People get extremely neutrotic about the most inconsequential environmental issues, but completely ignore all of the most impactful ones.
Aside from the existing well placed criticism like oil subsidies, I wish people were that passionate about using wood in conctruction instead of concrete. Switching to heat pumps where possible. Or not driving cars more than necessary or switching to smaller vehicles, like small electric cars, motorcycles, ebikes and bikes or public transport. Or that people would demand the end of corn and soy subsidies and biofuels, which are completely counter productive in their current form. Or that people care more about how zoning and building codes destroy the environment with things like single-family zoning, minimum parking requirements, banning mixed use etc..
I would like a more rational approach to environmentalism instead of this endless pointless virtue signaling, self-flaggelating and greenwashing.
But I get the feeling that things are going in the right direction at least.
I think things are going in the right direction, yeah. Things could be moving faster and we could be doing more, but I don't think that precludes all the little things either, it all adds up.
That is true, I think we are currently entering the exponential part of the technology curve when it comes the sustainable technologies. Progress over the next 20 years will be insane. Thing like cheap high density batteries, solid state magnetocaloric heat pumps, crazy advances in computing/automation/AI will all add up really quickly.
I'm also really looking forward to our daily lives not being subject to the whims of despotic fossil fuel states.
Yeah but when you consider that this massive show of goodwill came from the shriveled-up raisin that Ulf Schneider calls a 'heart', it's an improvement of 420%!
I’m pretty sure those savings would apply only on pitch black interfaces on OLED screens, IPS panels do not use less energy by displaying black, unless is the only color on screen.
If a UI is dark grey (like the Nestle one in this post screenshot), all of the diodes on an OLED screen are lit up, so there shouldn’t be any savings whatsoever.
Also, we’re far from having dominance of OLED screens in the smartphone market, which would be required for your scenario to apply.
