COMPLETE Energy Security notes

These are the complete full notes for the Energy Security topic with case studies. I've created this from multiple sources, including 2 geography textbooks and various other resources I've found online so it could be as detailed as possible. I did copy and paste some information when I got a bit lazy so there could be repeated information in some parts. Sorry for any typos! Please let me know if there are any or if there are any mistakes. Enjoy :)

Energy consumption: refers to availably and use of energy
Energy transition: Moving from traditional energy sources (biomass) of modern sources (fossil fuels) as a result of development

GLOBAL DISTRIBUTION OF ENERGY SOURCES
The physical geography of a location largely determines the distribution of energy resources. Where reserves of coal, oil…

Glacial valleys
However, the drawback of its high latitudinal extent means that it's solar potential is relatively low in comparison with
other parts of the world.
North America ­ Energy insecurity:
Large coal resources
Opportunity to exploit oil reserves in Arctic and Antarctica
Huge energy consumption ­ outweighs supplies

MEDCs:
The USA shows huge demands for energy resources
Germany and UK have improved their energy efficiency resulting in a modest increase in demand compared with NICs

MOVING TO MODERN ENERGY SOURCE
As incomes increase in developing countries, poor families can afford more modern appliances. These in turn demand more…

o the switch from fossil fuels to renewable alternatives is arguable because the benefits and disadvantages of switching
may not weigh up e.g. wind power is becoming increasingly competitive with fossil fuels, in the USA the installed cost
is around US$55 per MWh, almost the same as coal and gas.…

FUTURE TRENDS
Energy demand projected to grow by 50% between 2005 and 2030.
Growth is expected to be 0.7% per year in the developed nations of the world, but in the emerging economies of the BRICs and
other such nations, growth is supposed to exceed 2.5%. Coal use increased by…
