My son Keith is an Energy Economist in Washington. Three years ago he bought us an energy monitor. It has faithfully watched our system - telling us what appliances are on - how much electricity we are using - and what our bill will be.
As you can see by the above chart - while we were on vacation - our electrical use dropped dramatically.
The biggest use by far is heating and cooling. While we were away - we had the heat turned down to 60 degrees. We had left the refrigerator on - and it was the biggest user of power. We leave 14 lights on outside although they are only LED bulbs. We also had them dimmed down - so they use virtually nothing. I consider them a great preventer of theft.
I unplugged the TV's - but kept the internet on because then we can watch our home TV programming on our iPhones and also see our security cameras.
The hot tub was off and drained.
The electric car was unplugged.
We have a gas tankless hot water heater - so it was off.
The Washer - dryer - dishwasher - were off.
Our electrical monitor is called Sense.com. You can see the electrical use on your iPhone - you can even control devices from the iPhone.
