The reason I keep pushing these charts is to make the point that the big sustainable design issue is not how we build our homes and offices, but how we get to them. And that is a function of how we design our cities and how we get between our homes and our offices. That is the sustainable design problem of our time.
Between 2014 and 2015 our energy use for housing and offices dropped considerably, thanks primarily to the warm fall, but again, our transportation is up .6 of a quad because we are driving more and buying bigger cars and trucks.
Also, everyone keeps looking at the energy data, because it is a simulacrum of carbon, but the Livermore Lab actually does a carbon drawing; lets look at that.
