Update on the Nest I got my hubbie for his birthday back in April. This month's utility bill is 200 TWO HUNDRED dollars less than the bills for July of both 2010 and 2011. This is a 30% savings for us. THIRTY PERCENT. We have had the hottest June on record, so it definitely was not because it was cooler than previous years. We have a two story home, with three people home all day using computers and television, and we have a walk-in furnished basement, so our bill is naturally rather large in the summer. The month before, it was 100 dollars less than the previous June. It's totally worth it! nestthermostatsavingselectricityutility bill August 2, 2012
