Save energy, water and money with this cheap trick

Chances are there’s an Earth Day celebration near you this month. (Still looking for one? Check out EarthDay.org, which not only lists major events, but invites you to take a green pledge under its Billion Acts of Green campaign, which is very close to logging its billionth act.)
As you can imagine, I’ve been to dozens of green festivals and Earth Day fairs over the years. It’s a must for someone writing about green living practices. And it remains a pleasure.
