When you go into a grocery store, you shut your car off – letting it idle would waste gas (and invite thieves).  When you pause at a stop sign, you leave your car on – restarting it after one second would just waste time and energy.  And although these examples are rather obvious, Google’s now addressing the reasons behind Blackle, a dark search engine and would-be electricity saver.

When it comes to saving money, small amounts matter – spending a mere five bucks on lunch, five days a week, amounts to $1,300 per year.  In terms of saving energy, the same idea applies, and so Blackle – a dark version of Google – was born.
