Unit 3 - Topic 1, Energy Security Flashcards
Define Energy Security
Means to have access to reliable and affordable energy sources e.g. Russia - countries that do not have this and are therefore energy deficient are energy insecure
What are the important factors in achieving energy security?
- Control over supplies
- Control over prices
- Having a variety of energy sources to call on
- Political stability (in supply region as well as demand region)
Define non-renewable energy/finite energy
A non-renewable resource is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. The demand outstrips the supply. - e.g. fossil fuels
Define Fossil Fuels
A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms - they will eventually run out due to them being non-renewable
Define Resource Depletion
Is the consumption of a resource faster than it can be replenished
Define Renewable Energy
Energy from a source that is not depleted when used e.g. wind or solar power
Define Flow Resources
Renewables which do not need regeneration as these resources are constant supply - recyclable energy
Define Energy Mix
To meet its energy needs, each country uses the energy available to it, in different proportions - this is known as an energy mix. - Fossil fuels account for 80% of the energy mix
Define Recyclable Energy
Can be used repeatedly, if managed carefully e.g. biomass, nuclear
In what year did coal production drop drastically in the UK?
Since 1913
Which countries imports undercut energy prices in the UK?
America and Australian imports
In what year did oil production take off in the UK?
1970s
In 1985, how many barrels of oil were being extracted from the North Sea, by the UK each day?
2.5 million
What percentage of the UK’s energy needs is oil?
35%
What year did the UK discover gas?
1990s
In what year did Britain become a net importer of gas?
2004
By 2020, gas imports will account for what percentage of consumption?
80%
What year did the UK become the world leader in nuclear technology?
1990s
What energy source did the UK used to mostly rely on?
Coal - the use of coal consumption has reduced overtime
What energy source do the UK depend on?
They depend on imported gas through vulnerable pipelines - Russia supplies 30% of EU gas. When North Sea production started to decline the UK became a net importer of Gas in 2004. (Used to rely on oil but now rely on gas)
What wind speeds do wind turbines require to produce energy?
8-25 mph
What areas do solar panels work best in?
Works best in areas of over 6 kwh per square metre per day
Define Energy Poverty
Lack of access to energy resources in the developing world - they often rely on fuel wood, farm waste and dung as their fossil fuel consumption is low
What percentage of the world rely on fuel wood, farm waste and dung as their energy sources?
40%
By 2030, China will import as much oil as what country?
America
China need their energy so they don’t mind making deals with what countries?
Iran, Burma and Venezuela
What is China’s economy based on?
Manufacturing - China are more energy hungry
What is India’s economy based on?
More service-based
China and India’s net oil imports are expected to jump to what number per day in 2030?
19.1 million barrels a day - Up from 5.4 million barrels in 2006
By 2030, what is global oil demand expected to reach?
116 million barrels a day
What percentage is the use of coal expected to jump to in the next 25 years?
73% - due to the rise in oil and gas prices
What energy source do Japan mostly rely on?
Natural Gas
What energy source do China mostly rely on?
Coal
