Are you interested in saving the environment? Of course you are!

Guess what? Your environmental savvy could win you some cool prizes and cash!

There are three green-friendly contests you can enter after the jump!

First up isn't really a contest (I'm a big liar). But it will save you money, which is just as good as winning it. Toronto Hydro is still pushing its summer savings incentive program.

If you use 10% less energy, you'll save 10% on your bill! Toronto Hydro has a list of ways to help you make that happen. The program runs until the end of August.

The second contest (a real one this time) is brought to you by some of my favorite people on the internet! Tree Hugger, Instructables and Popular Science have teamed up to bring you their Go Green! contest.

To enter to contest, log on to the instructables website and submit your green DIY project before August 19th. The grand prize is a really sweet bike!

Even if you aren't a creative, brainy type I recommend checking out the site for some amazing green projects anyone can do at home.

The last contest is from Ryerson University and is open to students in full-time design programs.

Ryerson is looking for a redesign of Gould street. The street runs straight through campus, and students clash with vehicles on it every day. Ryerson wants to make it a pedestrian-only zone, which is something Toronto could use.

The contest could earn you $5,000, plus a street designed by you would look pretty great on a resume. The contest encourages students to get creative with street furniture, sustainable planting, and lighting. Submissions must be in by September 17th.

Good luck!
