Measure Your Green I.Q.

Find out how green you are, and how to become even more green, with the GreenIQ quiz. It asks you 15 simple questions about your lifestyle-such as the month you turn your heating system on, and whether you leave your devices on standby-and determines your intelligence quotient when it comes to the green lifestyle.

Serious greenies won't glean a whole lot from the quiz-if you've already changed to energy and money-saving compact fluorescent light bulbs, try to walk to some (or all) of your destinations and have taken steps to conserve water, this may not be for you-but if you're just starting down a greener path, it'll help take the pulse of your newly green life, and help point you in the right direction to go next.

And, if you're still in the test-taking mood when you're done with that, keep on clicking and test your polar bear I.Q.?
