Some of the changes we have made are: changing our light bulbs from incandescent to fluorescent bulbs. The next generation of screw-in fluorescent bulbs is here, they are more roundish than the older ones which look like a cross between spaghetti strings and a soft serve ice cream cone. You know which ones I mean! The light is a bit blue and faint when you first turn it on, but in a minute or so you can't tell the difference from incandescent. We turned off all of our outdoor lighting, which was nice to look out at, but not necessary. We also cut our pool pump run time in half, which didn't seem to affect the water quality at all. We make a conscious effort to unplug our TV's, phone chargers, and any small appliances when not in use that are otherwise just sitting there sucking juice all day.
We learned about solar tubes, shown above. Michael recently cut a circular hole in our garage roof and inserted this tube, which allows daylight to come through some sort of a prism which makes the area under the tube really bright. It looks like there is a light on, but you can't find the switch to turn it off. Very cool.
