1 KWH = 3412 BTU
1 gallon of heating oil = 130,000 BTU
So, 130,000 BTU per gallon of heating oil/3412 BTU per KWH = 38.1 KWH per gallon of heating oil
If your electricity cost is 10.5 cents per KWH, and you get 38.1 KWH for every 130,000BTU, then 130,000 BTU cost you $4.00 in electricity.
So if your heating oil costs less than $4.00 per gallon, it is cheaper to heat with oil.

This depends on the means in which you heat. Kerosene, or oil furnaces are some what efficient, and an electric heat pump is also efficient. (until it gets below 38 degrees F) So the question can't be answered directly until the system is known, but if they are similar in efficiency then it is just the cost of the fuel.

Energy is cheeper becasue in the winter the cold conditions make the oil more dense and thicker..witch is harder to burn meaning it takes more to generate heat.
