Huella ecológica y límites biosféricos
Electricity is produced from many sources: hydropower, coal, oil,
gas, nuclear, geothermal, solar, wind, tide and wave energy,
combustible renewables, and waste. Coal is the biggest source of
electricity worldwide, followed by gas, hyroelectric power, nuclear
and then oil.
Annually 2584 kilowatt hours of electricity were produced for every
person living on earth in 2002. The distribution of production is not
uniform - Benin and Togo only produce 10 and 11 kilowatt hours
per person per year, respectively. Norway and Iceland produce
almost 3000 times more per person per year. SASI Group, University of Shefield

Territory size is proportional to the percentage of world electricity
production that occurs there.

security and the economic output of our nation." United States

7. Agotamiento de la energía

Huella ecológica y límites biosféricos
This is a map of the depletion of some energy resources: coal,
crude oil and natural gas. These fuels are so slow to form that for
practical purposes they can be considered to be finite resources.
Shown here is the fall in the financial value of resources due to
current rates of fossil fuel extraction. Territories that extract a
lot, whether for internal consumption or export, have high 'energy
depletion'. In absolute terms the United States has the highest
depletion, followed by the Russian Federation, Saudi Arabia and
the Islamic Republic of Iran. Per person rates are highest in
Kuwait, followed by Saudi Arabia and Norway. SASI Group, University of Shefield

8. Agotamiento de la energía

Territory size shows the proportion of all annual energy depletion that
occurred there. Energy depletion is the loss of potential future income at
current prices due to current extraction of fossil fuels.

10. Huella Ecológica
The ecological footprint is a measure of the area needed to support a population’s lifestyle. This includes the consumption of food, fuel, wood, and fibres. Pollution, such as carbon dioxide emissions, is also counted as part of the footprint.
The United States, China and India have the largest ecological footprints. Without knowing population size we cannot understand what this means about individuals’ ecological demands. Large populations live in China and India. In both territories resource use is below the world average. The per person footprint in the United States is almost five times the world average, and almost ten times what would be sustainable.

“People consume resources and ecological services from all over the world, so their footprint is the sum of these areas, wherever they may be on the planet.”The Living Planet Report 2006

Territory size shows the proportion of the worldwide ecological footprint
which is made there

13. Emisiones de Carbono

Huella ecológica y límites biosféricos
SASI Group, University of Shefield
Carbon dioxide causes roughly 60% of the ‘enhanced greenhouse
effect’ or global warming resulting from certain gases emitted by
human activities. In 2000 there were almost 23 billion tonnes of
carbon dioxide emitted worldwide. Of this, 28% came from North
American territories; 0.09% came from Central African territories.
Emissions of carbon dioxide vary hugely between places, due to
differences in lifestyle and ways of producing energy. Whilst people
living in 66 territories emitted less than 1 tonne per person in 2000;
more than 10 tonnes per person were emitted by people living in the
highest polluting 21 territories that year.
