Matt, The best kept secret at all the power providers in my area of Arizona.
Personally I think everyday is cut your energy cost day. I always turn off lights in rooms with no one using them. Even with all of my lights being super efficient LED lights. I also use solar screens to block heat in the Summer and remove them in fall and winters. I have reversible inflector air tight screens inside on my windows.i can block or make heat by reversing them in seconds.
I also cook in my solar ovens anytime of years. It's fun and keeps food moister and healthier.
I also dribble electric in might efficient 2016 chevy spark ev. It is only about 50 cents vs a gallon of gas. I plugin at public free chargers when I am out running errands
