I've been googling to find the answer to this but have not found it yet.
We're renters, and the gas stove came with the house. I am not quite sure how old it is, but it is avocado green, so I'm guessing late 1960s-early 1970s. I've often thought of replacing it, because in summer, it tends to make the kitchen warmer. It's also hard to clean (for various reasons).
Today I was reading another frugality forum, and somebody mentioned having an old "energy guzzling" stove/oven. Is it possible my landlord's stove is an energy hog? I understand that old fridges are, and even old washing machines, but stoves? Never heard that one.
