Question for Gomer the scientist

Washington DC

Description

If the sun is the only thing that can heat up the earth, why do you have a furnace in your house? Since there are 7.67 billion people on earth, let's say there are 1.5 billion houses or so and that 1 billion of those also use a furnace to heat their houses 3-5 months out of each year. And they've been doing it for a couple hundred years. Since you're the expert scientist, I'll let you do the math and calculate the total cubic feet of 1 billion houses, the total BTUs needed to heat them all for 1 year, and the varying number of houses that have been heated over the last 100 years or so. Should be easy for a genius like you who understands everything without even having to look anything up. Even a low flame on the stove eventually cooks an egg, Gomer. It's not that tricky. Even a rural hick like you should be able to understand it.
