Summary edit
| Description |
English: “Balloon graph” representing quality (EROI – Y axis) and quantity (X axis) of the United States economy for various fuels at various times. Arrows connect fuels from various times (i.e. domestic oil in 1930, 1970, 2005 – “today”), and the size of the “balloon” represents part of the uncertainty associated with EROI estimates, i.e. larger “balloons” represent more uncertainty. The horizontal line indicates that there is some minimum EROI that is needed to make society work, and the vertical line to the left indicates one estimate of maximum forestry potential and the vertical line to the right is David Pimentel’s earlier estimate of total photosynthesis in the United States (Source: US EIA, Cutler Cleveland and C. Hall’s own EROI work in preparation). (Reprinted with minor changes from [6]). |
