Embrace your inner innovator, and put your green thinking cap on. You can enter to win these prizes out of a desire to do good for the environment -- or a desire to earn yourself some prizes -- or both:

Show off your DIY skills, win $500, a trip to NYC, a party, and fame. ReadyMade magazine’s new annual contest — ReadyMade 100 — will “celebrate the best 100 projects from the wide world of DIY.” Upload your project to ReadyMade’s contest by Dec. 15 for a chance to be named Main Maker — a title that wins you $500, a 3-night stay in NYC, a party thrown in your honor, and a feature in the magazine’s April/May 2011 issue.

Redesign a greener version of an office product, win $25,000. Staples’ 2nd Annual Global EcoEasy Challenge seeks greener design ideas from green-minded college students. Submit a 1,000-word description of your green redesign idea for a chance to win the $25,000 grand prize or one of the two $5000 runners-up prizes. The competition — which closes Dec. 23, is open to both undergraduate and graduate students.

Get your class to conserve, win a high-tech grand prize valued at $36,000. National Geographic’s Find Your Footprint contest invites teachers and their students to develop a project that’ll save water, reduce waste, or save energy. Submit the project by Dec. 3 for a chance to win the grand prize — five Promethean state-of-the-art interactive whiteboards, five classroom sets of Promethean Learner Response Systems, $1,000 in National Geographic educational materials and 30 subscriptions to National Geographic Kids magazine.
