This weekend marks the Summer Solstice, and do you know what that means? Heat! If it hasn't already gotten steamy in your hood, your time will come. Summer heat is fun when you've got Italian ices and a pool, but it also translates to a couple of not-so-eco-chic things. A/C and gasoline. If you park your car in the sun, when you return, you'll immediately reach for the a/c dial. The heat also causes the gasoline in your car to evaporate, which is certainly not good for your wallet or the environment. So, get in the habit of using your garage, or park under the shade of a tree in your lawn. Don't have a tree? Plant one.
