There's alot of talk on Earth Day about regulations (important!), SUV's (bad!) and recycling (keep it up!). However, I notice that sometimes people forget one of the biggest enviromental problems--how we're powering our homes and offices.
Austin has a Green Choice electricity option, as I'm sure many places do. Renewable resource energy options are often a little more expensive, but it doesn't have to be that way. By signing up for Green Choice, I locked into a constant rate for the next five years. As everyone else's prices skyrocket, mine will stay the same. And the more people who plug into wind farms and dams for their electricity, the cheaper it will get.
It was easy for me to switch over. I just emailed them, basically. Go to your local energy provider's website and see if they have similar programs. It's simple to do and is certainly just as important a decision as recycling and driving efficient vehicles.
