Reframing Smart Grid: “the Kernel” …Smart building (verb)!
Energy Flow – 100Quads …55% rejected
US Energy Consumption - Improvement starts at home/office.
Behavior choices… start at Home (office)!
Utility services – are traded & reconfigured on-demand!…fuel, heat, elec. - the biggest “footprint”? … Auto/transit choices (>50%)!

U.S. households account for about 38 percent of national carbon emissions through their direct actions, a level of emissions greater than that of any entire country except China and larger than the entire U.S. industrial sector.2 By changing their selection and use of household and motor vehicle technologies, without waiting for new technologies to appear, making major economic sacrifices, or losing a sense of well-being, households can reduce energy consumption by almost 30 percent ム about 11 percent of total U.S. consumption.3Potential savings of this magnitude have existed for at least three decades.4
It is therefore reasonable to ask why the potential remains largely unfulfilled and what can be done to achieve it. Lack of financial incentives may be one answer, but as the analysis in this article shows, much of the unfulfilled potential for reduction is achievable at low-, no-, or negative-cost. Other partial explanations include difficulties in financing expensive home etrofits, limited ability of renters to change energy use in owners ユ buildings, and the average householder ユ s limited amount of time and attention.5
