When you switch on your heat this fall, try setting your thermostat 1 or 2 degrees colder than you normally would.
Lowering your thermostat by 1 degree might not be noticeable to you, but can lower your energy bill by 2% to 3% - or lower your greenhouse gas emissions by 2% to 3%.
Similarly, in the summer, see how it feels to have your A/C 1 or 2 degrees warmer.
One degree is a small change, but I love the metaphor of a boat or a plane changing course by 1 just degree. When a boat adjusts its course by just 1 degree, it ends up in a very different place over the course of a few days, weeks, and years.
