With such cold temperatures sticking around Florida, I got to thinking, how much cheaper would it be to have natural gas to warm up the house versus electricity. Energy used to heat the house probably takes up the largest percentage of the electric bill (that is during cold times). Other big energy guzzlers like the water heater, clothes dryer, the oven can be powered by the natural gas as well. For my number crunching, I got most of the data from Energy Information Administration website.
National average for electricity in 2009 was 10.4 cents per one kilowatt-hour and 1.29 cents per one Therm of gas. Since one kilowatt-hour is equal to 3.412 therms, the electricity cost is 3.05 cents per Therm. So looks like the electricity was almost 2 ½ times more expensive than the natural gas.
