Why is The Screen So Dark on This Blog?
The reason the background color for this blog is set to black is because it actually takes less energy for your monitor to render black pixels than it does to render white or lighter colored pixels.
Less energy consumption means less carbon burned to generate electricity.
Is a few black pixels on a few computer monitor screens going to "save us from global warming?"
No, of course not. But the message here is that every little bit, taken in the aggregate, will start to make a difference.
The solutions start with a change in the way we think about how we go about our daily lives. So changing a light bulb, changing a blog background from light to dark, driving just a little bit less (or, if you’re lucky, not having to drive at all), these are the little changes that can build into significant progress in addressing the issue and reality of global warming.
Sometimes dark is light.

I started using Blackle for this very reason (not that I thin it will save the world, but just to further decrease my energy consumption). It is a google-based search engine.

Black is not (always) Green Black backgrounds can save some energy if you use a CRT screen (CRT screens are those huge and big screens). If you, like the majority, uses an LCD screen (the flat ones) a white background instead of a black will save energy. LCD monitors are built with a light behind the screen that is always on. So when you show a white page you just let the light shine through the screen. If you show a black page on the other hand the LCD light is completely blocked and it requires more energy to shine through. According to Google “displaying black may actually increase energy usage”.

Thanks for the comment Simon. This is admittedly, as I hoped I pointed out in my post above, pretty much a quibbling point. At this point a black screen is just the look and feel of this blog.
I may take down this post because there seems to be a lot of confusion about this and it just isn’t that big a deal one way or the other.
It’s probably much more effective to use “green” web hosts or otherwise try to “offset” or reduce energy use that way.
Do you have any suggestions in that regard?

As an environmentalist who’s worked to reduce my carbon footprint to less than 5 and who just canceled a vacation to New Zealand due to the impact, I think there are more meaningful things to do than focus on this quibble about the impact of black on CRT and LCD monitors. For heaven’s sake. You have a site devoted to communicating IMPORTANT information. The point is for it to be READ. As a graphic designer my experience is that white on black is significantly harder to read. For that reason alone, I’d consider switching it so more will read the content. Most of us use LCD monitors now anyway.
Thomas Schueneman @ 10:00 am:
Sheila,
Thanks for the comment. First, good for you for your effort to reduce your carbon footprint and the willingness to forgo the long flight.
I couldn’t agree more that whether this screen is black, white, or whatever is of little consequence in the larger scheme of things. The original idea may be getting a little lost at this point.
The comment previous to yours (which was just a cut/paste from a blog post) suggested using green hosts or offsetting carbon from the server farm hosting a site. Good points and I do that for this site.
As to the design aspect. When I decided to to this blog this way, my designer indicated something of the opposite of what you say.
That in the early days of talkies it was established that white on black was actually easier to read, and that the military also found white letters and numbers on a black background was easier to read.
I’m not a designer and I am not saying you are wrong. I’m just letting you know what actual research I did when making this decisiton. Granted it might appear stark to the millions of other blogs out there, and that might be a good thing. Thus far I have received very few complaints about this, and mostly along the lines that my assertion that a black background saves any energy is wrong.
I am always open to considering changes and updates to the look/feel of the blog, but I also have to remain true to what I think is best or what I want to do with this.
Thanks for your input.
