Black is the new green. Or rather, Blackle is the black Google. Because it's green. Am I making any sense?
Let me start again. Blackle is the Goth's Own Google. It uses the same search engine, except instead of a white background, it has a black background.
Why? Because Google uses more energy than Blackle. It takes more energy to make a screen white than it does to make a screen black. The thinking goes: everybody and their mother uses Google, so if everyone switched to Blackle, there would be a saving of 750 megawatt-hours a year. I'm pretty sure that if I knew what a megawatt-hour was I'd find that impressive.
I do know that using less energy is better for the world. Though, there seems to be some skepticism about whether or not using Blackle actually does save energy. And a lot of that seems to be coming from Blackle itself. They do a nice save by saying that if you use Blackle anyway, each time you see it, you will be reminded that we can all reduce our energy use in little ways, and that will have a profound effect on the planet.
Apparently, Blackle doesn't have all of Google's functions. And there's only so much reversed-out type (white on black) the human eye can comfortably read (this is something they teach you in art director school, even though they didn't cover those megawatt-hour things). The question then is, if Blackle may not really save energy, why use it? Well, because it's black. And black is cool (that's something else they teach you in art director school). You'll look cooler while you're googling yourself, or, at least, not quite as desperate.
And, you've got to give Blackle points for trying to be green.
Go Blackle Yourself.
