I was surprised at how much carbon was generated by my house. My total carbon output in the “Home” category was 3,864, only about a hundred kilograms above average. However, what really astonished me was the distribution within the category. While lighting was only 238 kilograms, which I had expected to be the biggest category, I noticed that the heating category contributed a whopping 2,715 kgs to the total- almost two-thirds of my home’s total carbon output!
   I believe the culprit to be our method of heating: the gas heater. By playing around with the settings on the calculator, I was able to confirm that just by switching to an electric heater, our family would emit almost 1,000 kgs less than we do currently! I feel that this is a change that could definitely be realistically made in not only my household, but in others as well.
   Other things I could do to reduce my house’s carbon emissions include replacing our incandescent lightbulbs with LED ones, rememb ering to turn lights off when they aren’t being used, and recycling things more often than throwing them away.

I honestly wasn't surprised with the carbon in my own household, since our family size is above average in the US. Even if my family was smaller, we would still have a better carbon footprint than average.
We rarely ever travel, keep the lights off until after it gets dark, have electronics of when not in use, don't keep the water running until we need it, and keep the heater off in the winter. I could go on but I agree that the heater and electricity overall is a major part in everyone's carbon footprint.
According to the article Sources of Greenhouse Gases, "Electricity production generates the largest share of greenhouse gas emissions. Approximately 67 percent of our electricity comes from burning fossil fuels, mostly coal and natural gas."
The only heating system we use would be our water heater, which comes from natural gas, and so I think that itself cuts down a lot on our total kg.
