Here's a little something for those of you that struggle to either understand or explain the link between energy and climate. I recently discovered a video ad by the Alliance for Climate Protection entitled "Black Balloons: Making CO2 Real." It is a great visual representation of what happens when we use energy at home - helping to illustrate the linkage. This is an especially challenging linkage to convey when we talk about energy use in buildings. Many have walked behind a car, unintentionally inhaled some exhaust, and coughed. No one has walked past a building with the same result. So, whether you're new to the environmental scene, or an expert in the field, you must check this out.
