Jenn's action: Have a smart meter
Smart meters allow for real-time feedback between your home and the utility company. This allows the utility company to operate more efficiently and also allows for time-of-use pricing, where energy costs more during peak hours, but less during off-peak hours.
Note: If you're already doing this action, take a look through each of the steps and make sure you haven't missed anything. If all's well, go ahead and check off all the boxes, then go start something new!
