Today is Earth Day, and the blogosphere is awash with hundreds of lists of green living tips that you are more than welcome to print out and tape to your forehead.  Or…you can celebrate Earth Day by sharing this one simple fact with your peeps: Going solar will shrink your carbon footprint by 7.4 metric tons a year!

What does 7.4 metric tons of CO2 look like? Well, if it were pure carbon dioxide, it would fill a space seven times bigger than the interior of your home. But our atmosphere isn’t pure CO2 – in fact, only 388 out of every one million molecules in the atmosphere are CO2. At that concentration, you would need to fill the Dallas Cowboys stadiums with air three times to get 7.4 tons of C02 – the same amount that your system is removing from the atmosphere every year!

Or think of it this way, going solar is an even bigger carbon offset than if you stopped driving completely!  Your car isn’t the biggest contributor to climate change…it’s your house!

Bottom line:  Home solar is the #1 way to go green. Do it today (and then go buy some organic tofu and reusable water bottles).  Happy Earth Day!
