Your Single Source for Comfort and Energy Solutions
Ever wonder where our country's energy comes from and goes to? This fascinating map from the Lawrence Livermore Labratory shows in simple graphic terms where we generate energy and how much of it goes to various sectors. One of the fascinating aspects of this is everything you see in gray--"Rejected Energy." What this really means is waste. Particularly in electricity, as much as 2/3 of all the energy created is lost during transmission and via other means before it actually does any work. All the more reason to generate your electricity right at home on your roof.
In this installment of Green Building Advisor's "Job Site Visits" series, building science guru Joe Lstiburek explains why insulating a house to the highest standards won't do much good if the home still has significant air leakage.
The graph below shows which structural air-leaks drive up energy costs the most, allowing you to maximize efforts toward reinforcing your home's building envelope.
