This question already has an answer here:
There are claims that blackle.com conserves energy given that it is darker themed and produces less light. There is a counter under the search box that constantly increases. But in today's era of computers, laptops, tablets etc does it really conserver anything? Yes screen brightness affect battery life but does it make any big of an effect? In laptops which are plugged in? In desktop computer monitors which consume the same power anyhow as long as they are showing something?
What are the scientific facts behind this?
If it really does conserve energy, will I (as an end user), by using it, actually see any benefits on my electric bill?
