Participants got more successful at saving energy in their
challenges, as shown by the following pie charts. The chart on the left
is for fiscal 2009 and the pie chart on the right is for fiscal
2014/2015. The dark green pie segment show the percentage of people who
were successful with their 10% challenges, while the light green
segments are those who had some savings but less than 10%.
Survey data suggest that participants gained the bulk of their
evaluated savings through changes in four main groups of behaviors:
space heating, space cooling, laundry, and dishwashing. Team Power Smart
members tended to outperform non-members across the full spectrum of
in-home conservation behaviours. Although some differences are
relatively small in percentage points, nearly all are statistically
significant.
