DIFFICULTY: Easy
Here's a really easy one! If you aren't already using Goodsearch, or you'd just like to try out a new search engine, or you're really set on using google for your searches, try SavesWatts! Savewatts helps save energy because the screen is black instead of white. I'm not really sure about the whole science behind it, but apparently black backgrounds use less energy than white ones. The great thing about it is that it is a customizable google search, so you don't have to really switch search engines! According to the site, they've saved 870.45 Watt-Hours to date!
