Thanks to everyone who entered the Earth Day giveaway to win a set of five reusable grocery bags.

I asked for eco-friendly ideas and wanted to mention a few of the most clever ideas  submitted before announcing the winner.

The Earth Day festivities continue....

Kroger is celebrating Earth Day all month long by giving away free reusable shopping totes.

Submit a design for a tote and you'll receive a free bag for your efforts.

If the "design" requirement has you stumped, don't worry. Kroger's made it easy on you.

In honor of Earth Day, I'm giving away a set of five reusable grocery bags from Harris Teeter.

Leave a comment or question below and you'll be entered to win.

I'd love to hear your eco-friendly tips, of course, especially those that save money and help you tread more lightly on the planet.

I'll pick one winner at random on Tuesday evening.

Good luck and happy Earth Day!

Who wouldn't want to celebrate Earth Day with slices of pie? The fourth annual SEEDS pie social is 1-5 p.m. April 22.

The event raises money for the Durham Inner-City Gardeners, an urban-farming leadership development program for teens. You may have seen these teenagers selling their produce at the Durham Farmers' Market on Saturday mornings.

The cost is $10 for four slices of pie. Almost 30 restaurants and several home bakers have signed up to donate pie, including Acme Food & Beverage Co., Foster's Market, Guglhupf and Papa Mojo's Roadhouse. The pies will range from classic sweet desserts to pizza. New this  year, a panel of judges will declare one pie as the Best in Town and the public will vote for a People's Choice favorite.

While eating pie, attendees can bid on lessons in the skill share auction where instead of buying stuff, you can learn a skill. Among the lessons up for bid are how to fly a plane, brew beer, bake bread and cook Indian food.

The garden is located at 706 Gilbert Street, Durham. The event will happen rain or shine. For more information, go to http://www.seedsnc.org.

Did you get a chance to venture out to Durham's Earth Day Festival yesterday? Check out our gallery from the celebration.

There are a few more events on tap this weekend to celebrate Earth Day:

The PBS Kids Go! series 'Arthur' is helping kids get into Earth Day today with the launch of five brand new episodes about environmental protection, cultural awareness, and teamwork. 

The first episode airing is "Buster Baxter and the Letter from the Sea." In this episode, Buster discovers a message in a bottle on the beach while on vacation with the Read family and begins sending his own messages by throwing bottles into the ocean. Buster and Arthur ultimately learn that keeping the beaches and waterways clean is the real message.

Here's a chance to do some good for the planet and earn some green for yourself.

AAA Carolinas is hosting its annual Great Battery Roundup, a used battery
collection and recycling program, as part of 2011 Earth Week activities, through April 23. For every auto or marine battery you bring to any AAA Car Care Center or Approved Auto Repair shop this week, you get $1.
