Lights, refrigerators for "off the grid" lot trait

There are some things that don't say they work off-the-grid, but they still function a little. I thought refrigerators wouldn't work at all, but apparently you can still put things in them and get food out of them. Grills and candles work, but the lamps that look like oil lamps are actually electric. I haven't gone through and tested everything, but these were the things I was most interested in!
