- Quantitatively EF (Mathis Wackernage, et al, 1990’s)
- EF (Ecological Footprint) Ξ Land area necessary to provide for the current way of life (w/average hectacres)
- Where land area is total cropland, grazing land, forestland, and, fishing grounds, and built-up land needed to maintain a given population at a given lifestyle; plus the forest land needed to absorb the carbon dioxide emissions from the fossil energy used by the population.

Fossil Fuel Resources Figure 6. The green energy future scenario. Solar and wind energy grow at 25%/yr, while nuclear power and coal as energy sources grow at 1%/yr as is currently the case. Finally, nonconventional oil and gas development are not pursued and therefore too small to be visible in the plot. - Brecha, Berney, and Craver, Am. J. Physics, Vol. 75, No. 10, October 2007
Figure 7. The nuclear-supplemented fossil-fuel energy future scenario. Wind energy grows at 10%/yr and coal grows at 1&/yr. while nuclear power as an energy sources increases at 10%/yr beginning in 10 years to allow for ramp-up. Solar is too small to be visible. - Brecha, Berney, and Craver, Am. J. Physics, Vol. 75, No. 10, October 2007
Total and per capital energy use for nine selected countries. The Human Development Index (HDI) is a rough measure of standard of living. In general, higher HDI correlates with higher per capita energy use. - Brecha, Berney, and Craver, Am. J. Physics., Vol. 75, No. 10, October 2007
