INTRODUCCIÓN


Chomsky, Hegemonía o Supervivencia

Producción de energía


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 ofelectricity worldwide, followed by gas, hyroelectric power, nuclearand then oil.Annually 2584 kilowatt hours of electricity were produced for everyperson living on earth in 2002. The distribution of production is notuniform - Benin and Togo only produce 10 and 11 kilowatt hoursper person per year, respectively. Norway and Iceland producealmost 3000 times more per person per year.

Producción de energía


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

“Energy supply and demand plays an increasingly vital role in our national security and the economic output of our nation." United States

Department of Energy, 2006


Agotamiento de la energía


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 forpractical purposes they can be considered to be finite resources.Shown here is the fall in the financial value of resources due tocurrent rates of fossil fuel extraction. Territories that extract alot, whether for internal consumption or export, have high 'energydepletion'. In absolute terms the United States has the highestdepletion, followed by the Russian Federation, Saudi Arabia andthe Islamic Republic of Iran. Per person rates are highest inKuwait, followed by Saudi Arabia and Norway.


Agotamiento de la energía



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

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.

Emisiones de Carbono



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.



Territory size shows the proportion of carbon dioxide emissions in 2000 that were directly from there.
