An Op-Ed in Forbes magazine suggests a simple but brilliant idea - emissions stickers for buildings: Link When cars are regulated for the pollutants they put out, the average home needs to be regulated as well. While this may make some homes more expensive, there are a number of technologies to make homes vastly mroe energy efficient using bolt on methods like double glazing, energy efficient doors, insulation etc. At my home itself, we installed energy efficient insulation lasst year - it paid for itself over the winter in saved heating expenses and it will last five more years. Of course, there are ultra-modern methods available which could make a difference in the future if they are applied more widely.
Color me impressed and this is one mroe reason to read Forbes IMO!
