What would natural gas cost to produce the same BTU a 7 cent kilowatt of electricity produces?

The answer to this depends on the cost of natural gas. In my area, natural gas is about $11 US per 1000 Cubic Feet or basically 1.1 cents per cubic foot. At the same time, electricity in my area is 10.9 cents per kilowatt hour. Neither of these costs include taxes and customer charges so the actual cost is actually higher.
To answer the question though, one kilowatt is the equivalent of 3416 Btu. One cubic foot of natural gas has 1030 Btu per cubic foot. So we need 3416/1030 or 3.3 cubic feet of natural gas. At 1.1 cents per cubic foot that is 3.63 cents of natural gas.
Now if you were using these to heat water, an electric heating element transfers about 98% of it's energy to the water. A natural gas heater only transfers about 65% of it's energy to the water while the rest goes out the flue pipe. So the 1 kilowatt of electricity transfers 3348 Btu to the water. To get the same heating with natural gas would require 3348/.65 or 5150 Btu of natural gas. So 5150/1030 is 5 cubic feet or 5.5 cents of natural gas. Still considerably cheaper than using electricity in my area.

What is produced by a generator?
The general term generator is usually applied to the kind of generator that produces electricity, or electric power.
What kind of natural gas is siphoned off from some landfills and burned to produce electricity?
Methane is commonly burned at landfills. It is not siphoned; it is a byproduct of decomposing materials inside the landfill. Since methane is lighter than air, it rises from the ground. Burning it keeps the landfill safe and is a great source of energy.
