1. Maximize energy efficiency in buildings.
The operation of buildings accounts for 48% of greenhouse gas emissions in the United States according to the Pew Center on Climate Change. In New Hampshire, 32.3% of the net energy consumed in 2005 was used to heat buildings and structures, and another 36.6% was used to generate electricity, much of which is used in buildings . The construction and operation of buildings, therefore, represents a major contributor to greenhouse gas emissions. The state can realize substantial reductions in its energy consumption for heat and power by maximizing the thermal and electrical efficiency of all future buildings and extensively retrofitting existing residential, commercial, industrial and municipal buildings. This will lead to significant and direct reductions in energy costs and greenhouse gas emissions. Such actions can begin immediately by implementing the most cost-effective investments in energy efficiency immediately and incorporating more advanced technologies when they become economically viable.
