The other day as I was dropping off my daughter at her kindergarten class, I ran into my friend Dave's family. I was surprised to see them all — mom, daughter, and son — riding their bikes to school!

As I watched them pedaling with a parking lot full of SUVs  in the background, I thought to myself, "They're definitely doing their part to save the environment!"

I guess I shouldn't be surprised, since Dave rides his bike to work everyday. But it did get me thinking about what I'm doing. I recycle my paper, glass and plastic at home religiously — even my 2- and 5-year old daughters know that bottles and cans go in the "circle" and that regular trash goes in the "square." But every little bit helps, and I always wonder what else I can do to make a difference.

Then, as I was browsing through the Rewards programs available through my Wells Fargo credit and debit cards, I came across a "Green" option...cool!

I was planning to go for an Amazon gift card, but now I think I'll redeem 5,000 points and get a Renewable Energy Certificate. The best thing? Each certificate supports 6,000 kilowatt hours of green power — that's like planting three acres of pine trees!

I know there's a lot more I can do, and I am always trying to learn as much as I can about how to be green. In the meantime, if I'm already going to use my debit card for necessary purchases, then at least I can feel good that I can do something for the environment. And as a Wells Fargo employee, it's nice to know my company is giving customers an eco-friendly choice.

What do you think about Green Rewards? Does having an environmental Rewards option matter to you?
