It’s only going to save power if you’re using an oled, since for most lcd screens the backlight is on whether you display black or white.
All my websites are jet black, and the black is only really black on my phone which has an oled screen.
Either way, it’s just greenwashing. These companies are only pretending to give a crap so they can get brownie points with people who can’t see what they’re doing.
Most lcds take a tiny bit of current to darken a pixel I think. The ground state would be white and power is used to get the lcd in the state where it changes the lights polarization to get it blocked by the polarization filter in front of it
Yes, I think it’s this way around because precision is higher at higher power, so the minor deviations close to no voltage applied are hidden in minute white variations, while near blacks are way more precise. But don’t quote me on that
Back in CRT days, the difference between full white and full black could be as much as 100W. Before dark mode existed, people developed sites like Blackle to reduce the power usage of Googling.
What does this save, like a milliwatt per year? One of the stupidest things I have ever seen.
Sending the JavaScript to do this literally uses more electricity than this saves.
This is classic. Corpos that are the biggest polluters are also the ones that push hardest on the idea of “carbon footprint”
The more they can convince people that climate change is their fault, the less likely people vote for a government that will regulate the corpos
Throughline (podcast) did an episode on corporations off-loading responsibility for stuff like this onto the populace.
Found it: episode is called “The Litter Myth.”
Don’t worry, they’ll vote for a government that regulates the people and not the corpos
Plus all the energy used in developing the feature in the first place. What a crock.

I assume that would depend on the polarization of the screen. I wonder which is more common?

Traditional LCD screens actually use more power to make black.
OLED screens might save a tiny bit of power though.
They can’t do any good in the world. This is the best they have to offer.
Greenwashing was never about effective practical solutions. It’s always been gaslighting and marketing.
It’s almost comical, especially coming from Nestlé
