* | Steam | Average New Yorker | Consolidated Edison- Steam System | New York City: urban area () | 0.000598 | proportion (0-1) | To calculate this value we first referenced NYSERDA (2012) to surmise the total number of households in New York City that use fuel for space heating. After subtracting the number of households that do not use space heating from the total number of households in the city, we then portioned out 1,771 households from the "Other" fuel category (the rest of which is counted as natural gas heating) and divided by the number of households that use fuel for heating. |

We assume all the "other" fuel is steam in Manhattan. | |

* | Wood and other biomass | Average American | U.S. Department of Energy 2012 - 2011 Buildings Energy Data Book | US: Buildings (2010) | 5.5556 | % proportion (0 - 100) | We calculated this value by dividing this fuel's space heating energy (quadrillion Btu) by the total site energy of space heating (quadillion Btu). We then converted the calculation to a percent. Wood space heating is included in the "other fuel" section. The notes sections attributes 0.42 quad Btu to wood space heating. |

* | Wood and other biomass | Average Earthling | IEA 2011 - Statistics & Balances | Global: All (2009) | 2.903368 | % proportion (0 - 100) | This is the proportion of production of heat in the world from "other sources". |

Then we divided the number of housing units that use this fuel type for space heating by the number of occupied housing units that use fuel. We then converted the calculation to a percent. |
