I find a flaw with your argument. The question is not "are the major gas appliances the primary drivers for household emissions". That seems true and obvious. It is "does replacing them with electrical versions lower total emissions"?
Meanwhile, you seem to be using different definitions of household emissions. Your first source about 95% seems to be talking about direct emissions, ignoring the impact of electricity generation. Your second source about the size of the problem (20%) seems to include electric production.
- rlg2161 4y agoParagraph 2 of my response: > The 2nd figure accounts for carbon footprint of electricity generation used in the home as well as gas combusted in the home. The 4th chart from [1] suggests this is about a 50/50 split (if we bring grid emissions to 0 but don’t exchange these natural gas devices, carbon intensity remains at half of what it is today). Therefore, we can conclude that these 4 appliances in residential properties account for 10% of US carbon footprint. To your first question - the answer is yes; replacing gas appliances with modern electric appliances is less carbon intensive, even if the electricity is produced by fossil fuel combustion. This will become increasingly true as the grid gets greener over time and the carbon intensity of electricity production continues to drop
