I spent Thanksgiving week in Arizona with my parents, who are very energy conscious although my father says “I find my thoughts are more of efficiency than saving the planet, however the results are the same.” Last year I thought he was crazy to be
turning off the computer and the surge protector for the TV system (TV, DVD player, etc.) every night to reduce “vampire energy,” or
standby power drains.
During a discussion on
energy audits, he showed me his most recent month’s power bill. A really neat feature (if bills can have good features) is that the power company includes on the bill a small bar graph that shows the present year’s power use vs. the previous year’s use by month.* The graph shows very clearly that after an increase in energy use in January and February of this year over last year, when temperatures were slightly lower (= more heat), my parents had a HUGE decrease in the average daily kWh used over the summer months – up to a 22% savings in July, when the average temperature was over 94°! (The Phoenix area had temperatures over 114° this summer, and the daily range can be over 30°.) Their energy savings have continued into the fall, ranging from 8% to over 17%.
