In the years that I've lived in my house, I've lost electrical service approximately twice a year, for (so far!) only a few minutes/hours at a time, due to equipment failure, accidents knocking poles down, squirrels committing suicide, etc. Being that natural gas is a commodity delivered to your house just like electricity, is it really reliable enough to depend on in an emergency? I don't believe I've ever lost delivery of natural gas, and even if I did, I probably wouldn't know it for a few hours. In winter, I'd notice sooner as the furnace wouldn't work, though in summer I wouldn't notice until the hot water wasn't as hot as it should be or the stove didn't work. Has anyone lost or know of anyone that lost natural gas delivery, for any reason? I'm just wondering if it's wise to depend on an emergency fuel source that you have no control over.
