Ch2 Counting the Cost of Reliance on Fossil Fuels Flashcards
PGTC
List 4 factors causing increased fossil fuel usage
- Population growth
- Goods and services
- Travel
- Capitalism
Define fuel security.
The uninterupted availability of energy at an affordable price for a nation or region
Breifly explain the Oil Crisis of the 1970s
- 1973 Yom-Kippur war sparked an embargo of oil by the middle east to all nations supporting Israel.
- The USA was affected by this
- Oil prices qaudrupled
What 3 long term impacts did the 1973 oil crisis have on the world?
- Car manufacturing shifted from the USA to nations like Japan
- Stimulated Britain to drill for oil in the North Sea
- Developed nations began to seriously consider energy conservation, recycling and alternative forms of energy
Outline the impact on Ukrainian energy when Russia annexed Crimea
- Russia annexed Crimea in March 2014, previously a part of Ukraine
- Diplomatic strains between Ukraine and Russia
- Ukraine were reliant on Russian natural gas and in June 2014 the gas supply was cut
Perfect example of how quickly fossil fuel supply can be halted
Deforestation & Rising sea levels
Comment on habitat degradation in relation to fossil fuel burning
- Deforestation - Trees cut down to exploit fossil fuel reserves -> Animal habitats destroyed
- Rising sea levels - Global temperatures rising cause polar ice caps to melt -> Animals suffering are the polar bears
Comment on air quality in relation to burning fossil fuels
- Combustion of fossil fuels releases soot and NOx gases which are hamful to human health
- Believed 40000 deaths in the UK a year are linked to air quality
Efficiency =
Useful E out / Total E in
Outline the 4 steps of generation of electricity within a fossil fuel plant
- Combustion of fossil fuels within furnace
- thermal energy released is used to evaporate water into steam
- Steam used to spin turbine - steam cools down and is ejected into cooling towers
- Steam condenses in cooling tower and falls as water to repeat process
Name one emerging economy and describe its impact on fossil fuel demand.
- India or China
- Increased industrialization raises global demand and accelerates depletion
List 3 ways a nation can increase its fuel security
- Reduce fossil fuel reliance
- Form international alliances
- Develop renewable sources
