This reverts commit 1882244.
per EIA 2022, natural gas emits 55.0 gCO2/ft3 when burned, but per "Life Cycle GHG Perspective on U.S. Natural Gas Delivery Pathways" (Littlefield, Rai & Skone), supply chain adds an average of 12.2 gCO2e/MJ (11.6 gCO2e/ft3) to the lifecycle embodied carbon, with the actual amount varying by region.

A sankey chart used to display energy usage (gas and/or electric) can now convert the native energy units (kWh or cubic feet of gas) into their corresponding monetary cost or CO2 intensity.
Cost:
Note that while HA's Energy Dashboard knows and tracks utility prices, the API does not make them available to us outside of over-summarizing statistics like total cost. Thus utility cost must be supplied to the sankey config, and only fixed rates are supported.
CO2 intensity:
For carbon intensity, we are able to use (abuse) the HA API to actually get the carbon intensity of all electricity usage on an hourly basis. Gas is assumed to have a fixed (but configurable) carbon intensity of 66.6 gCO2 per cubic foot.
