What is the pattern with energy consumption
HICs use much more energy than LICs
Why has energy consumption increased
economic development, increasing population and developments in technology
Factors that affect energy supply
geology, climate, cost of production and exploitation, technology limitations and political factors (e.g. conflict)
Impacts of energy insecurity
potential conflict, exploitation in an area of a sensitive ecosystem, economic/environmental costs, reduce in food production (biofuel), manufacturing more expensive
Advantage and disadvantage using coal for energy
adv:reliable and abundant dis:finite fossil fuel
Advantage and disadvantage using oil for energy
adv:can be moved over long distances, creates jobs dis:costs are increasing
Advantage and disadvantage using gas for energy
adv:most environmentally friendly fossil fuel dis:gas is explosive
Advantage and disadvantage using biomass for energy
adv:solves waste disposal problems dis:production of food often reduced
Advantage and disadvantage using hydro for energy
adv:dam can run for up to 100 years dis:habitats flooded and destroyed
Advantage and disadvantage using solar for energy
adv:captures both electrical and thermal energy dis:weather dependent, high production costs
Advantage and disadvantage using geothermal for energy
adv:no GHGs or pollutants emitted dis:expensive and complicated when needing to drill deep underground
Advantage and disadvantage using wind for energy
adv:can be on/offshore, no pollutants dis:weather dependent, noise pollution
Advantage and disadvantage using tidal for energy
adv:highly predictable and reliable dis:only optional to countries with access to large water bodies
Advantage and disadvantage using wave for energy
adv:renewable, clean dis:high construction costs
Advantage and disadvantage using nuclear for energy
adv:large stocks of nuclear fuel dis:hazardous waste produced as byproduct, one mistake=big consequences
What kind of energy are many HICs moving towards (e.g. the UK)
Renewables
How many barrels were carried through pipelines per day at its peak
2 million
How many jobs rely on the oil industry in Alaska
41 000
How much money does oil bring into Alaska’s GDP
$20 billion (half of total GDP)
How many barrels are left in Alaska’s North slope
50 billion
When did production begin
1977
