If traveling is part of your plan this weekend (or any weekend – ever), make sure you take the steps to save energy when on the road. If you're staying more than one night, throw that towel on the bar after you shower so you can reuse it again tomorrow. And, just like at home, be sure to turn off the lights and water when you're not using them. Even though you're not technically paying the utility bill, the energy you use still matters. Better yet, to make a bigger impact, check in at one of these eco friendly hotels.
