Agriculture households contribute disproportionally to global poverty: three out of every four poor people belong to this group (see Table 21.4). In other words, arable is much the same as being fertile. Perhaps the best way to compare the secular energy gains at a household level is to compare installed electric power. [8], Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Laborers on these farms, and other local people, thus may have little to no access to the food produced.

In 1900, a typical urban U.S. household had only a few low-power light bulbs, adding up to less than 500 W.

Fossil fuels and electricity have helped to create the modern world by driving up farm productivity and hence drastically reducing agricultural populations, by mechanizing industrial production and letting the labor force move into the service sector, by making megacities and conurbations a reality, by globalizing trade and culture, and by imposing many structural uniformities onto the diverse world.
