15. Here's a simple tool on the EPA website. Note they use "non-baseload" factors. https://www.epa.gov/energy/greenhouse-gases-equivalencies-calculator-calculations-and-references …

16. Marginal analysis is most appropriate when evaluating changes in electricity consumption, say due to an efficiency measure.

17. Marginal analysis is also the most appropriate when evaluating gas appliances versus electric.

18. This digression was important because marginal analyses suggest efficient gas use will play a role much longer in a decarbonizing grid.

19. To illustrate: If a new gas appliance displaces some electricity, I’m not actually (generally) removing any renewables from the grid.

20. My new gas appliance *will* remove some amount of gas- or coal-fired generation - the marginal resources - from the grid.

21. If we simply the analysis the question becomes: to use natural gas in a furnace or in a power plant (plus end-use heating appliance)?

22. In most places where homes must have heat for winter, a natural gas furnace results in less CO2 than a heat pump.
