Most people don't keep track of their energy consumption. All they know is that their bill is higher every year. Most people do use reasonable efforts to cut fuel costs, such as buying an electronic setback thermostat so the temperature is a little lower at night, or during the daytime when you are away from home. More ambitious people might install new attic insulation when they get a new roof put on. Others will chose new double insulated windows, with the real benefit being much lower sound level from outside. And people do buy smaller cars for energy efficiency.
So don't bug your neighbors. But do observe whether they have new windows, a small car in the driveway when they had a big SUV before, a new roof, a new roof ventilation system (like the wind powered turbine style).
