Water heater is gas. Checked on a timer for hot water usage...Have it set on standy instead. Keeps the temp in the 60's so it don't freeze. Found when you start using hot water the newly heated water is first out of the tank. Ends up plenty warm for the amount of hot water we use, ie showers. Otherwise you'd never notice.

Have just one door garage opener. Put a wattmeter on it. Uses less than 1 watt listening for the opener. Considered putting a wall switch in and only powering the opener when a car is out. Don't know if that messes with the remote programming though.

Have thought about powering down wifi, but haven't come up with a convenient way to do it. Computers, phones, TV, Stereo, printers, all use wifi.

Have a couple of internet servers wired and not on wifi. The watt meter says when inactive they only use 15 watts total for the servers external drives, router, and modem. The servers go to low power sleep and wake up for network activity. They don't have monitors, bluetooth, or wifi turned on since they are servers. They also cache most active files in memory and the drives sleep as well.

Been kind of entertaining seeing what saves electricity and what doesn't.
My electric company has a web site I can see hourly electricity usage and cost.
