KQ1 - What are the sources of energy and how do these vary in their global pattern? Flashcards
what is energy mix?
the mix of different types of energy that a country produces and consumes. This varies by country, for a number of reasons.
what are some sources of energy?
oil natural gas coal renewable energy nuclear
what are some renewables?
solar
wind
HEP/tidal/wave
geothermal
where is oil globally
60% in middle east (saudi arabia, turkey, UAE)
where is natural gas globally
1/3 in Europe and Eurasia
where is coal globally
50% in pacific (india pakistan china australia)
physical factors affecting FOSSIL global energy supply
Deposits of fossil fuels are only found in several locations
physical factors affecting SOLAR ENERGY
Solar power needs strong sunlight and often
physical factors affecting WIND ENERGY
Wind power needs strong winds
physical factors affecting TIDAL ENERGY
Tidal power stations often require a very large tidal range
physical factors affecting BIOMASS ENERGY (wood, peat)
Availability of biomass varies due to climatic conditions
Economic factors affecting global energy supply
ACCESSIBILITY
ONSHORE/OFFSHORE
TRANSPORT LINKS/INFASTRUCTURE
ENERGY PRICE
how is the economic factor ACCESIBILTY affecting global energy supply
more accesible and cheapest deposits of fossil fuels developed first
how is the economic factor ONSHORE/OFFSHORE affecting global energy supply
on shore is usually cheaper than offshore
how is the economic factor INFASTRUCTURE affecting global energy supply
Potential hydroelectric sites close to major transport routes + existing electricity transmission areas are more economical to build on than in inaccessible locations
how is the economic factor ENERGY PRICE affecting global energy supply
• When energy prices rise significantly, companies spend more on exploration and development
what POLITICAL factors affect the global energy supply
permission from International Atomic Energy Agency
international agreement
anti-pollution agreements
Kyoto protocol…
…can have infulence on energy decisions of several countries
what 3 sources provide the most energy worldwide?
Oil, natural gas coal
where is energy consumption highest, MEDC’s/NIC/LEDC’s
- MEDC’s (UK + US)
- NIC’s (china)
- LEDC’s (Mali)
What is an NIC
newly industrialised country
what is ‘proven oil reserve’
how much oil we have
supply shock?
a significant interruption to supply due to an environmental, economic or political event
peak oil production (POP)?
he year in which the world or an individual oil producing country reaches its highest level of production, with production declining thereafter.
