John's recent post on burning coal and CO2 got me to thinking. Yes, that can be dangerous,
especially when I was thinking while driving. BTW, I got home safely.
My math question has multiple parts. Last January my electric bill was a little under 3000 kw-hrs. February bill was a little less, but my Jan bill was the biggest. To make the calculations easy, let's say I used 3000 kw-hrs to heat my 2000 sq ft house with resistance heat, electric baseboards.
1. Calculate the BTU's in 3000 kw-hrs.
2. Calculate the CO2 produced by the most efficient power plant to generate 3000 kw-hrs:
A. using coal?
B. using NG?
3 Then using the best geo-heat pump on the market, calculate the CO2 generated by the best power plant to produce the BTU's in question 1:
A. using coal?
B. using NG?
4. Calculate the CO2 produced the make the BTU's in question 1 by using the most efficient:
A. NG furnace?
B. LP furnace?
Please list what efficiencies,% or COP, you used to answer the questions. I went with a geo only because during my coldest month, a good chance an air to air HP would be on back up. Some of my night time temps sub zero and day time highs may have been in the teens and 20's .
I haven't crunched the numbers yet. ONLY GUESSING, the furnaces will produce the least CO2. Because the methane molecule is one carbon and 4 hydrogen and the LP molecule has 3 carbons and 8 hydrogen, My GUESS is NG will produce less CO2.
Have fun. Be interesting to see how good of a guesser I am or not.
