Each time I’ve attended a green festival or green living expo, I’ve come away with some piece of information or a product that has made a significant difference in my life. Sometimes it’s immediate, sometimes it’s months or even years down the line.

I just found out through Live Green — which I learned about this spring at the Arlingtontians for a Clean Environment Green Living Expo — is hosting a Green Living Expo on Saturday, September 8, from 10 to 4 p.m. at the UDC/Van Ness Courtyard, 4200 Connecticut Avenue Northwest, Washington, DC 20008. I’m told they have over 50 exhibitors in addition to the UDC Farmers Market to welcome the over 1000 registered attendees. It’s a free event, but let them know you’re coming at by registering at Eventbrite. When you get there, put in for a chance to win a bag with some great green goodies, including a gift card from Relay Foods (formerly Arganica). There will also be lectures and activities throughout the day, and the event goes on rain or shine.

If you’re busy this weekend, have no fear. There’s more green living coming to DC later this month!

It was disappointing for lots of folks I know when the Green Festival decided to skip DC last year, but it’s back this year, September 29-30 at the DC Convention Center. It’s a huge event, worth going both days (and leaving the kids at home for one of them). Go in with an open mind, an empty bag, and a credit card to pick up wonderful deals on clothing, skin care, craft items and more. It’s a great place to buy all your holiday gifts and stock up on unique and sustainable hostess and birthday gifts. I’ve never even had a chance to listen to any of the amazing speakers, but you could make a whole day just out of that.

Unlike this weekend’s local event, the bigger Green Festival is not free, but there are usually some coupons you can score and there are volunteer opportunities, too. Check for updates at www.greenfestivals.org/wdc/updates/
