I am terrible at math, but I love energy calculators! I plug in the numbers and they do all the hard work. When’s the last time you used a carbon footprint calculator? Try this one from the Environmental Protection Agency and see how your energy usage compares to the usage of other Americans. I like this calculator because in addition too seeing how you stack up against your neighbors, you learn about small changes you can make to shrink your footprint. In the next few posts we’ll talk more about water calculators, electricity calculators and nifty ways you can reduce your consumption.
