Economic growth, modernization and the energy revolutionEconomic growth tends to be very energy intensive especially in early stages
Organic economies (subject to photosynthetic and land constraint) replaced by fossil fuels

Energy transition from crops and fuel wood to fossil fuelsTransitions take decades to play out
Coal does not displace biomass as dominant source until 1900, oil replaces coal in 1960s

Energy transitions increase total consumption of energyCheaper energy increases consumption and encourages new uses
New sources complement rather than substitute existing sources in early/mid stages
![Page 5: Natural gas and the global energy transition - Reuters › gfx › ce › 7 › 6939 › 6921... · 2019-10-16 · Gas plus renewables will meet extra energy demand in OECD to 2050](https://reader036.fdocuments.us/reader036/viewer/2022081611/5f03bbb17e708231d40a808b/html5/thumbnails/5.jpg)
Energy revolution is only just beginning for much of world populationConsumers in middle/lower-income nations use fraction of energy in high-income countries
Fast-growing economies will account for most global consumption growth in 21st century

Gas is replacing coal as dominant fuel for heating and power generationGas is superior fuel in most respects
Coal has lost traditional price advantage as a result of shale revolution and LNG
Gas advantages
❖ Complete combustion
❖ No waste (ash, slag)
❖ No particulate pollution
❖ No mercury/sulphur pollution
❖ Pipeline distribution
❖ Easier handling
❖ Cheaper, faster power plant building
❖ Greater flexibility
❖ Faster ignition
❖ Quick dispatch
❖ Load-following
❖ Complement intermittent generation
❖ LNG improves long-distance maritime
transport
Coal advantages
❖ Cost
❖ Geographical distribution
❖ Supply security
❖ Fuel security
❖ Long-distance maritime
transportation

Gas revolution: “the golden age of gas”Gas is replacing coal for economic reasons rather than politics
Global shift rather than national
Shale revolutionmore availability and cheaper fuel
Combined cycle gas turbinesincreased efficiency in power generation
LNGlong distance ocean-shipping
Urban pollution concernsreduced air pollution especially in cities
Climate concernsreduced CO2 emissions

Gas has been growing share of power generation since early 1990sGrowth pre-dates shale revolution and tougher climate change policies
![Page 10: Natural gas and the global energy transition - Reuters › gfx › ce › 7 › 6939 › 6921... · 2019-10-16 · Gas plus renewables will meet extra energy demand in OECD to 2050](https://reader036.fdocuments.us/reader036/viewer/2022081611/5f03bbb17e708231d40a808b/html5/thumbnails/10.jpg)
Gas and coal-fired generation both increased until 2007Increased electricity consumption accommodated both gas and coal
![Page 11: Natural gas and the global energy transition - Reuters › gfx › ce › 7 › 6939 › 6921... · 2019-10-16 · Gas plus renewables will meet extra energy demand in OECD to 2050](https://reader036.fdocuments.us/reader036/viewer/2022081611/5f03bbb17e708231d40a808b/html5/thumbnails/11.jpg)
Slowdown in electricity growth sharpened gas-on-coal competitionGas would have eventually started to squeeze coal’s share of power generation
![Page 12: Natural gas and the global energy transition - Reuters › gfx › ce › 7 › 6939 › 6921... · 2019-10-16 · Gas plus renewables will meet extra energy demand in OECD to 2050](https://reader036.fdocuments.us/reader036/viewer/2022081611/5f03bbb17e708231d40a808b/html5/thumbnails/12.jpg)
Electricity consumption growth has been decelerating for decadesIn static generation market, growing share for gas must come at expense of coal
Shift has been sustained and accelerated by shale revolution keeping gas prices low

Exports provide additional flexibility for market balancingOver- and under-supply increasingly balance through trade as well as inventory changes
![Page 19: Natural gas and the global energy transition - Reuters › gfx › ce › 7 › 6939 › 6921... · 2019-10-16 · Gas plus renewables will meet extra energy demand in OECD to 2050](https://reader036.fdocuments.us/reader036/viewer/2022081611/5f03bbb17e708231d40a808b/html5/thumbnails/19.jpg)
Gas price volatility has generally fallenBalancing across a bigger international market rather than a smaller national one
Pricing basis is shifting from national inventories to LNG market

Conclusions (1)
Energy system always in transition
Transitions driven by long-term economic and social forces rather than politics
Uptake of new energy sources and technologies follows logistic or S-curve
Transitions usually play out over decades (50 years plus)
New energy sources increase total consumption by making energy cheaper and
allowing it to be used in new ways
New sources are normally additive rather than substitutive at least in the early
and mid-stages
Legacy sources can continue growing in absolute terms for decades even as
their market share shrinks
Unmet global energy demand will require significant growth in energy from all
or almost all sources over next 30 years

Conclusions (2)
Gas set to become an increasingly important part of global energy mix
Gas likely to displace coal in electricity generation for reasons of cost and
convenience as well as pollution and climate concerns
Gas will complement renewables in electricity system – at least for the next few
decades
Gas consumption set to rise in absolute and relative terms through mid-century
Gas dependence will create new source of insecurity for importing nations
