What activities can you recognize in these pictures?

INDUSTRY

TRANSFORMS RAW MATERIALS INTO…

MANUFACTURED PRODUCTS for direct consumption in the

market.

SEMI-FINISHED PRODUCTS to be used in other industrial

processes.

Industry requires 3 elements

ENERGY SOURCES

PRODUCTION FACTORS:

- Labour force (employees)

- Capital (buildings, machinery, money…)

- Technology (knowledge)

RAW MATERIALS

MINING

LOCATES, EXTRACTS AND REFINES ROCKS &

MINERALS FOUND ON/BENEATH THE SURFACE.

PROSPECTION:

to locate the minerals.

EXTRACTION:

to obtain the minerals from subterranean &

open-air mines.

REFINING:to separate the

mineral from the rock that contains it.

ENERGY PRODUCTION

CREATION OF ELECTRICITY & HEAT IN SPECIALISED

INSTALLATIONS (POWER STATIONS).

NUCLEAR

WATERSOLAR

THERMAL

CONSTRUCTION

CREATES BUILDIGNS & INFRASTRUCTURES* (roads,

bridges, reservoirs,…)

PLANSBUILDING

MATERIALS

CONSTRUCTION

INDUSTRY

*INFRASTRUCTURES: basic facilities, services & installations needed for the functioning of a society and its economy (transportation &

communications systems such as roads, bridges, tunnels, etc., water supply, sewer systems, power lines…)

INDUSTRY

• Core elements:

• Raw materials

• Energy sources

• The world’s energy.

Energy saving.

• Industrial development and its landscapes:

• Artisanal industry

• Modern industry

• Contemporary industry

• Industry and globalisation

CORE ELEMENTS OF INDUSTRY:

RAW MATERIALS

RAW MATERIALS = Natural resources that industry transforms

into manufactured or semi-finished products.

PLANT-SOURCED

From agriculture: sugar beets, cotton, linen, tobacco

From silviculture: wood, cellulose, rubber, cork…

ANIMAL-SOURCED

From livestock farming: wool, hides (leather), silk…

From fishing: fish (for canning & oil production)

GEOLOGICAL

Minerals: metallic (iron, lead, aluminium, copper, zinc…) & non-metallic (glass, gems…)

Rocks: granite, clay, limestone, marble,… (direct use or to produce construction materials like cement)

Energy products from which energy is obtained: coal, crude oil, natural gas, uranium…

RAW MATERIALS Production & trade

CONSUMPTION (demand): concentrated in INDUSTRIALIZED COUNTRIES

1) WESTERN EUROPE

2) JAPAN

3) USA

4) Emerging countries:

Look at the map… is the distribution of minerals around the world equal?

Which countries produce large quantities of minerals?

RAW MATERIALS Production & trade

PRODUCTION: concentrated in few countries:

1) Canada

2) USA

3) Brazil

4) South Africa

5) Russia

6) China

7) Australia

Which region produces the largest quantities of oil?

Do you know what COLTAN is? What is it used for? Where does it come from?

COLTAN: essential mineral in modern technology (cell phones, laptops, cameras…)

80% of World’s coltan D.R.C. (Democratic Republic of Congo)

D.R.C. / Uganda / Rwanda / different rebel paramilitary groups WAR to

control the coltan mines.

Consequences:

• Slavery, child-labour, violence, murder, violations,…

• 5 million deaths

• War refugees

• Destruction of rainforests & species (gorillas, elephants)

• Farms are abandoned

• Coltan contraband finances rebel paramilitary groups

RAW MATERIALS Contemporary problems

PROBLEMS RELATED TO RAW MATERIALS

SCARCITY OF RAW MATERIALS FOR FOOD INDUSTRY

SCARCITY & UNEVEN DISTRIBUTION OF GEOLOGICAL RAW

MATERIALS

Food prices increase due to

a higher demand (increasing

population) of agrarian raw

materials. Worst impact on

the poorest people.

In order to ensure their supply,

wealthy countries try to control

trade with producer countries

& international markets.

Devise an outline about the main activities of the secondary

sector (p.130)

P.132, exercise 1.

Are raw materials distributed equally around the world? Where

do production & consumption concentrate?

ENERGY SOURCES

TRADITIONAL

NATURAL GAS

NUCLEAR FISSION

HYDROELECTRIC

ALTERNATIVE

BIOMASS

GEOTHERMAL

NUCLEAR FUSION

•Most widely

•Mostly non-

renewable

(except

hydroelectric).

•60% oil &

Traditional energies

•Most widely used.

•Mostly non-renewable (except hydroelectric).

•75-80% oil + natural gas + coal however, there are differences

between countries.

Traditional energies

• COAL more widely used in

developing countries (China) than

in developed ones (UE, USA).

Traditional energies• RENEWABLE ENERGIES are gaining ground to

non-renewable energies, specially in developed

countries.

Traditional energies: CRUDE OIL

Traditional energies: NATURAL GAS

PRODUCCIÓN

MUNDIAL DE GAS,

Traditional energies: COAL

COAL CONSUMPTION IS IN CLEAR REGRESSION DO TO ITS HIGH POLLUTION LEVELS (CO2 EMISSIONS)

Traditional energies: NUCLEAR FISSION

Traditional energies: HYDROELECTRIC• Only traditional energy that is

RENEWABLE!!!• Growing importance.

1984-2009

Alternative energies

Development

after the

1973 Oil

Crisis

NEED TO

SEEK NEW

ENERGY

SOURCES, TO

EXTERNAL

ENERGETIC

DEPENDENCE.

YOM KIPPUR WAR (6-25 Oct. 1973):

• Coalition of Arab states (led by Egypt & Syria) VS Israel (who received help

from the US).

• Egypt and Syria attacked Israel unexpectedly, since they wanted to regain

the Sinai and the Golan Heights respectively, territories that were occupied

by Israel since the Six-Day War (1967).

• CONSEQUENCE: in response to U.S. support of Israel, the Arab members of

OPEC (Organization of the Petroleum Exporting Countries), decided to

reduce oil production & declared an embargo against the USA and other

Western countries, causing the 1973 energy crisis.

Alternative energies

ADVANTEGES: they are renewable & clean (they don’t pollute or generate waste).

DISADVANTAGES: necessary technologies to develop them are still too expensive.

However, in time renewable energies are expected

to became cheaper, while fossil fuels will became

more expensive.

Alternative energies: SOLAR

Alternative energies: WIND

Alternative energies: BIOMASS

Alternative energies: GEOTHERMAL

Alternative energies: WAVE

Alternative energies: NUCLEAR FUSION

With 1gr of hydrogen we

could produce, by means of

nuclear fusion, in an hour,

11 times more energy than

by current nuclear fission.

ITER (International Thermonuclear

Experimental Reactor)

• International project to design and build an experimental fusion

reactor.

• South France.

• 7 member entities (EU, India, Japan, China, Russia, South Korea &

• EU (host party for the ITER complex), contributes with about 45 %

of the cost. The rest 9& each.

ACTIVITIES

On the political World map, locate the main production

countries of traditional & alternative energy sources.

In groups of 4-5, make up a song about the different types of

energy sources… BE CREATIVE!!!! Record it and send it to

rocio.sociales@gmail.com.

• The Kyoto Protocol: UN international treaty that

committed State Parties to reduce greenhouse gases

emissions (CO2), to stop global warming. It was adopted in

Kyoto (Japan) in 1997.

• SPECIFIL GOAL: to reduce, in the period 2005 - 2012,

collective emissions of greenhouse gases by 5%

compared to the year 1990.

• 2012: technically the K.P. was extended until 2020, but

limited to only 15% of the global C02 emissions, due to the

lack of participation of many industrialized & emerging

countries such as: USA, Canada, Japan, Russia, Belarus,

Ukraine, New Zealand, China, India & Brazil.

• 2014: new negotiations were held in Lima (Peru) to agree

on a post-Kyoto legal framework that would obligate all

major polluters to pay for CO2 emissions. However, some

large polluting countries (China, India, USA) indicated that

they will not ratify any treaty that will commit them legally

to reduce CO2 emissions.
