6.2 global energy consumption

Developed countries

Use more energy on a per capita basis & use more energy in total (higher population)

-the average US resident uses 5x as much energy as the world average

Developing countries

Still industrialized and population is still growing rapidly

-it increases on a per person basis as their economics industrialized & residents achieve higher standards of living

Fossil fuels examples, hydroelectric energy, nuclear

Most used energy sources (fossil fuels)

• oil → gas → fuel

• coal → fuel for electricity

• natural gas → 2nd fuel for electricity

-hydroelectric energy: dams used to create electricity, 2nd largest source of

-nuclear: creates electricity, 3rd largest source

Development increases fossil fuel consumption

-less developed nations depend on subsistence fuels (biomes that can easily gather/ buy → wood, charcoal, animal poop → can drive deforestation)

-economic development is affluence by wealth which leads to higher GDP

-as developed nations develop fossil fuel consumption increases

Factors that affect energy source use

Availability: fossil fuel depends on discovered reserves and accessibility of these reserves

Price: fossil fuel prices fluctuate dramatically with discovery of new reserves or depletion of existing ones
