Summarising Energy Security Flashcards
The main way to classify energy is between renewable, non-renewable and recyclable sources. Define these
Renewable = can be used over and over again e.g. wind and solar power
Non-renewable = these are finite resources so as they are used up the stock that remains behind is
reduced
Recyclable resources = fuel that has been used once can be used again to generate power e.g. nuclear
reprocessing can make uranium waste reusable
What factors influence the suitability of an energy source?
Start up time
Affordability
Accessibility
Renewability
How many people live without electricity?
1.6 billion
Define fossil fuel.
Those formed over geological time from the partly decayed remains of plants or animals.
They include coal, oil and gas and can be combusted only once and a therefore finite and non renewable.
What are future trends likely to be in terms of energy demand?
China and India expected to have the largest rises.
Countries in Western Europe may reduce their demands as a result of improved energy efficiency and rising energy costs.
Developing world countries expected to double by 2020, while it increases by about one third in the developed world.
Why does energy security matter?
Energy is fundamental to how society and the economy functions and develops.
It is vital to maintain quality of life.
A country loses control over its affairs if it has to rely on other countries for energy.
Countries can be vulnerable in a crisis.
Unstable/unreliable energy and prices make planning difficult.
The Oil Drum (UK case study)
2006- 92% of the primary energy consumed in the UK was derived from fossil solar fuels - oil, natural gas and coal.
UK WAS self sufficient in these energy resources but now importing much more.
Dependency = less energy secure upon imported energy undermines UK national security and will have potentially dire consequences for the balance of trade.
What are 6 alternative energy sources?
Smart Meters- cutting down excess use of resources within a household.
Transition town- community works together to become less reliable on fossil fuels.
Community Energy- producing energy locally and working collectively.
Solar thermal energy- harnesses solar energy to generate thermal and electric energy.
Offshore wind turbines- generates electricity from kinetic energy from wind.
CHP- heat that is normally wasted in conventional power generation is recovered as useful energy.
What are energy pathways?
Give an example
The flows of energy from producer to consumer are the pathways.
Trans-siberian pipeline, the main conveyor of Russian natural gas exports.
Oil pathways
The middle east exports around 15,000 barrels per day, mainly to Japan, Europe and China.
Substantial amounts flow from Africa, Europe and Canada and central America to the USA.
What is OPEC?
What are its aims?
Organisation of Petroleum Exporting Countries, a permanent intergovernmental organisation of twelve oil-exporting developing nations.
- protect the interests of member countries
- stabilise oil prices
- ensure efficient, economic and regular supply of oil
What role does OPEC play in energy supply?
Sets oil production quotas for member countries in response to economic growth rates and demand-and-supply conditions.
•If demand rises, it can increase oil production to prevent steep price rises.
•If demand falls, oil can be reduced to stabilise the price.
How powerful is OPEC as a player?
It has around 78% of the world’s oil reserves.
It produces around 45% of the world’s crude oil and 15% of natural gas.
Fracking has reduced their power, USA able to produce their own oil.
Energy Security and Energy Pathways: Research
Somali Pirates- Made an illegal coast guard: developed into the pirates- taking oil tankers and charging a ransom.
Nabucco Pipeline- Passes from Azerbaijan to the EU and can carry 100 billion cubic metres of gas per year making up 1% of Europe’s total demand.
Hurricane Katrina- 2005, Damaged the US refinery and production.
Oil Crisis: 1973- OPEC raised posted price of crude oil $3 to $12 per barrel for US allies- lead to recession.
First Gulf War- 1991- Having a war stopped oil production.
What is the UK doing to try end become more energy secure?
UK is investing in a £2bn nuclear plant deal to try and combat energy security issues built by Chinese.
Nuclear energy is expensive and the waste is difficult to expose of.
Relying on China doesn’t reduce energy security problems.
Takes at least 10 years to build.
What are some responses to increasing energy demands?
Business as usual
Multi energy solution
Energy conservation
Energy in Contrasting Countries-UK
Consume less energy today compared to 1970 due to increased efficiency eg 3 million tonnes compared to 53 million.
In the late 2020s, nuclear is also set to contribute more as the UK’s new generation of nuclear power stations come online.
43% of fossil fuels from abroad.
Energy in Contrasting Countries- Mali
Mali is a landlocked country in North Western Africa.
Typical characteristics of LEDC: increasing population due to high birth rate, low life expectancy (53), low adult literacy rate (74%) etc.
70% of the population is in rural areas
Decentralised energy production for a decentralised population.
86% of the energy they use in in household.
Tiny amount of electricity but of that is hydropower (70%) and thermal power plants.
93% of the population use firewood and charcoal as primary source of energy.
Between 5 and 10% has access to electricity
Less than 5% has access to modern energy services
