The Energy Issue
What are the sources of energy and how do these vary in their
global pattern?
The global energy mix is made up of both finite (fossil fuels and nuclear power) and renewable
sources (e.g. HEP and wind) in which they vary, depending on their availability over time and space.
Global Pattern
Oil Coal Natural Gas Nuclear Hydro
Where it is Relatively Asia Pacific, Europe and Rare but South and
the major common, 50% Eurasia, 33% Europe at Central
source? Middle East 10% America,
has 50% 28%
Reserves 1,208,000 Over 3 trillion 181 trillion m3 Few built Limited as
million barrels tons since best sites
Chernobyl used
Chief areas 61.5% 27% USA Mid East 41% Main reserve Asia
of reserves Middle East Eurasia 35% of uranium in
Asia
Chief user USA China Russia France China, Brazil

gas and oil unconventional
sources
Factors Influencing the Energy Supply
Physical Economic Social Political
Climate (wind, water, Technology Safety Agreement with
solar) neighbours/borders
(e.g. international
rivers)
Water supply Demand Noise Security

Vegetation type and Site Pollution (air, water, of Anti-pollution
volume (bio fuels) solids ­e.g. acid rain) agreements
Tidal range Transport (of fuel and Opposition from
energy) voters
Geology (fossil fuels, Cost of fuels/ operation Quotas on renewables
geothermal)
Waste Disposal Cost
Term:
Energy Mix: the relative contribution of different energy sources to a country's energy
production/consumption
