This article describes how residential energy consumers measure and an
alyze their own energy consumption and energy costs. Using in-depth in
terviews, we find more extensive data collection and analysis by resid
ential energy consumers than has been previously documented in the ene
rgy literature. However, the conclusions consumers can draw from their
analytical efforts are restricted by the form their analytical effort
s are restricted by the form in which they receive price and consumpti
on data and their limited analytic capabilities. The relative informat
ion processing strengths of consummers are compared with those of inst
itutions such as energy utilities, leading to the conclusion that many
of the analytic tasks are currently assigned to the less efficient pa
rties, degrading decision quality and creating a market barrier to ene
rgy conservation. We suggest a more efficient allocation of data colle
ction and analysis between the consumer and energy utility.
