Even with replacing our ICE car with an EV, we are using about half of the electricity compared to what we were using 15 years ago. As lights burned out we replaced them with LEDs. As appliances wore out we replaced them with high efficiency ones. We also added switches to outlets of devices that have parasitic loads - like TV, microwave, and laptops. We added insulation to the attic and crawl space.
One of our biggest savings was replacing our chest freezer with a 24VDC one with battery and solar panels. It only pulls from the grid a few months a year when the battery gets too low. Since we are going to cover the deck for summer shade we will do a solar panel shade for more solar power.
