If you are in an apartment where the gas is paid, that makes sense.
The advantage of the crock pot is you can throw a beef stew together, put it on low and can come home to eat right away.
You can't come home and have dinner ready with gas.
True. And that may be the only benefit. However, it consumes a lot of electricity as you would have to keep it on for hours. One of these days I'm gonna start using it. I know beef and rice come out much tender than cooking it conventionally.
