Transitions & Global Energy Flashcards
What does the World Economic Forum define an ‘effective energy transition’?
It must be…
Timely
Inclusive
Sustainable
Affordable
Secure
Providing solutions to global energy-related challenges WHILE creating value WITHOUT compromising the balance of energy
When does energy transition project to take over?
From fossil-based to zero carbon by the second half of this century (2050)
How much can renewable energy and energy efficiency measure achieve of required carbon reduction?
90 %
What is energy transition enabled by
IT
Smart technology
Policy frameworks
Market instruments
What does ‘mitigation’ compromise?
Reducing the flow of heat-trapping GHG by reducing sources OR enhancing the sinks
From 1990-2019, what anthropogenic emissions have risen?
Fluorinated gases: 2%
Nitrous oxide (n20): 4%
Methane: 18%
Co2 from land use & forestry: 11%
Co2 from fossil fuel industry: 64%
Pathways that limit warming to 2C (>67%) involve what?
Rapid and deep and immediate GHG emission reductions in all sectors
What does modelling mitigation strategies to reduce emissions include?
Transitioning from fossil fuels to zero-carbon energy sources
Demand side measures and improving efficiency
Reducing non-CO2 emissions
Deploying Co2 removal methods to counterbalance residual GHG emissions
What are some feasible transition scenarios?
Direct electricity reaching 65-70 % final energy demand vs 19 % today
Hydrogen accounting for 15-20 % final energy demand - of hydrogen-based fuels (ammonia, synfuels)
Use of biomass as bioenergy/bio-feedstock (constrained by sustainable supply)
A carbon capture role and storage or use in applications that ensure long-term sequestration
What are the three pinnacles of the ‘Energy Transition Index’?
Equitable
Sustainable
Secure
Core enablers: regulations & political commitment + finance & investment
Given an ETI Score.
What countries share of primary energy is from low-carbon sources? (nuclear/renewable)
Brazil, Scandinavia, Canada, and New Zealand
The ‘carbon intensity of electricity’ is the number of what?
Grams of Co2 it takes to make 1 unit of electricity at 1 kw/hr
Kuwait, Iran, and Russia are the leading carbon intensive countries as of 2021
What regions have leading ETI scores?
Europe, lead by Sweden at 78.5, followed by USA and UK
What leading mitigation energy solution will provide the greatest contribution to emission reduction?
Solar energy at >4 GtCO2-eq / year
Followed by wind energy at >3.5 GtCO2-eq / year
What has enabled the falling of unit cost of low-emission technologies since 2010?
Innovation policy packages, supporting global adoption.
Such as batteries for EV, solar cells, on/offshore wind and concentrating solar power.
From 2010 to 2019, what percentage decrease in unit costs of solar energy, wind energy, and lithium-ion batteries have occured?
Solar energy: 85 %
Wind energy: 55 %
Lithium-ion batteries: 85 %
With large increase in their deployment (10x for solar and 100x for EVs)
What country/region has the leading electricity share of renewable generation?
European Union
More than how much of global ELECTRICITY comes from low-carbon sources BUT less than total energy?
1/3 at 36.7 %
84.3 % of total energy from fossil fuels
What are two sectors hard to decarbonise?
Transport (heavily reliant on oil) and heating (heavily reliant on gas)
What Australian state is set to be the first to run on 100% renewables?
South Australia
What sector is the biggest source of Co2 globally?
Industry
12Gt of Co2 per annum
Progress towards net zero will be enabled by new production process using low/zero GHG electricity, hydrogen, fuels, and carbon management.
40% less emissions from heavy industry by shifting to circular economy

Transport
8Gt of Co2 per annum
ROAD: 20% of energy related CO2 emissions
250% expected growth in heavy-duty transport volumes
Requires low-emission liquid fuels from bio or syntenic sources
