Energy Flashcards
What is primary energy
Fuels that provide energy without undergoing any conversion process eg coal
What is secondary energy
Energy that is made from the processing of primary fuels et electricity.
What is the pattern of global energy consumption
Developed countries have a high energy consumption, countries which have easy access to natural resources have higher energy. Countries in warmer climates require less heating but may neeed air con, developing countries have low energy consumption
What are 4 reasons for the increase in global energy demand
Global population increase, economic development, increased wealth, diversification of energy resources
How does global population increase, increase energy demand
More people require more energy
How does economic development increase energy demand
As countries develop, economic activity shifts from primary to secondary, then secondary to tertiary/quaternary. Services and manufacturing have much higher energy requirements
How does increased wealth increase global energy demand
Increased disposable income achieving a consumer lifestyle. Involves the use of technological devices eg cars which are energy hungry
How does diversification of energy sources increase global energy demand
New technology allows us to extract electricity from previously inaccessible sources meaning we can consume more energy
What is the energy crisis
Where countries have a interrupted supply of energy or cannot afford to provide energy
What is the energy gap
Occurs when a country’s energy consumption is greater than its ability to produce energy, it has to make up this deficit by importing energy from other countries
What is energy surplus
When the energy supllly is greater than the demand
What is energy deficit
When the demand for energy is greater than the supply
What are 5 non renewable energy sources
Coal, oil, natural gas, uranium, shale oil
What are 5 renewable energy sources
Solar, wind, HEP, geothermal, biomass
What is a advantage of non renewable energy courses
Reliable and cheap with a high energy density
What is a disadvantage of not renewable energy cources
High carbon emissions when combusted
What is a advantage of renewable energy sources
Clean energy source with no carbon emissions and no contribution to climate change
What is a disadvantages of renewable energy sources
Can be expensive to set up and maintain
How does the uk manage energy security
Reduce the contribution of fossil fuels to the energy mix, increasing investment and development of renewable energy sources, increase self sufficiency of energy supply
What is one example of energy resource management
Uk gas boiler ban
How do Nepal increase energy security
Reduce reliance of fuel wood, increase investment in renewable energy sources, investing in local scale energy generation schemes
