2.1 - Energy Mix, Consumption, Transition (Ukraine Flashcards
What does primary energy refer to?
- actual original source of energy
- eg. Coal, oil, gas, solar etc.
What does secondary energy refer to?
- The form in which energy is consumed
- eg. Electricity, kerosene, petrol, diesel etc.
How much of the global energy mix is satisfied by fossil fuels?
> 80%
What does the term energy mix refer to?
The proportion of primary energy resources it consumes a year
What is energy security?
- the uninterrupted availability of sources of energy at affordable prices
What determines the success of an energy security strategy?
- long term investment in energy supply that meets economic and environmental needs
- short term ability of system to react to changes in supply and demand of energy
- is able to predict and adapt in real time
What does the energy mix of an energy secure nation look like?
- uses a mix of energy sources to prevent overdependance
- mostly homegrown
How high is Ukraine’s energy risk?
- 175% higher than the OECD average
- worst score out of any European country in the large energy group
How large are Ukraine’s coal reserves?
- 7th largest in the world
What is the energy mix of a pre industrial nation like?
- mix of biomass, waste
- cheap + part of subsidence lifestyle
- used directly for cooking
What is the energy mix of an industrial nation like?
- gradual introduction of fossil fuels for power stations and transport
- using basic technology (eg. coal furnaces in power station)
- mainly domestic sources of energy
What happens as a result of the energy mix of an industrial nation?
- Makes mass transport and car ownership more popular
- shift in demand towards efficient technology after this
- potential shift to nuclear and natural gas
- may even become more reliant on foreign sources of energy
What is the energy mix of a post-industrial nation like?
- Nuclear and renewables based
- limited by cost
- using clean energy sources
What else needs to be done other than changing energy mixes to make a post industrial country more energy secure?
- research of sophisticated technology eg. Hydrogen fuel cells
- limited by R&D and investment into this
- clean energy sources
- emissions targets dictating energy use
- ensuring energy mix plans are cost sensitive
- affordable by all
How does energy consumption evolve as a country develops?
- globalisation occurs
- power grids are developed
- population also grows, growing middle class
- disposable income
- middle class people buy appliances
- increased energy consumption
- after a certain point energy consumption decreases
- as people grow more concerned about environment
- results in appliances becoming more efficient
- lighting technology improves
