At the risk of sounding like a luddite:
Off and on I will think about how people want to treat the internet as a utility. We try to conserve water, we try to conserve electricity, we are metered for these. For phones, we pay for minutes, though you can opt for unlimited plans, and the infrastructure is such that unlimited plans don't burden others. For cars, we have gasoline (though technically not a utility), and when gas is cheap, people buy larger vehicles. When the price of gas goes up, people become concerned about gas efficiency.
Noone is terribly concerned about "conserving" the internet, or conserving computer resources. Every year computers get faster, and every year websites get less efficient. More bloat, bigger images, more script nonsense. They find more ways to update the browser, to make it smarter and yet more bloated. My NoScript and RequestPolicy plugins are so laden with websites that aren't obviously related to the one I'm on. If I'm lucky, there are one or two sites with a related name, or a CDN, and I can allow these and continue on. If not, I sometimes temporarily allow all, sick of going down the rabbit hole and just wanting to get to my destination.
I'm sure there is an electricity cost related to the extra computing. The time required for page loads is simply time you've wasted, unless you have managed to multitask a few pages. A site taking 15 seconds more than it did a year ago isn't a lot one time, but it adds up page after page, day after day. Even mobile versions of sites, using 4G services, load slower than they did years ago.
I just want my information, I want it simple, and I want it now. I'm sick of all this crap that is designed to make my life better somehow. I liked my life the way it was. I liked being able to do Verbatim searches on Google and actually getting verbatim results. I don't need fancy maps that take 10 times as long to load, I need simple maps that work fast when the network is congested. I don't need functionality changes to make things look slicker. I want to be able to do more with the hardware I have, and we just keep going in the opposite direction.
