Tipping the energy world off its axis
 Four large-scale upheavals in global energy set the scene for the new Outlook:
 The United States is turning into the undisputed global leader for oil & gas
 Solar PV is on track to be the cheapest source of new electricity in many countries
 China is switching to a new economic model & a cleaner energy mix
 Electricity is broadening its horizon, spurred by cooling, electric vehicles & digitalisation
 These changes brighten the prospects for affordable, sustainable energy &
require a reappraisal of approaches to energy security
 There are many possible pathways ahead & many potential pitfalls if
governments or industry misread the signs of change

Energy intensity is steadily falling down
The global energy intensity decreases by 2.3%/year to 2040, falling short of the SGD target by 2030;
China witnesses the fastest decline in energy intensity due to structural changes

In addition to gas savings of 580 bcm through demand efficiency,
supply efficiency in gas-fired power generation leads to a further 275 bcm saved to 2040

An IEA strategy to universal electricity access
On-Grid
Mini-Grid
Off-Grid
Existing grid
 Grid extension for 150 million additional people,
with hydro accounting for the lion’s share
 Decentralised solutions, mainly solar PV, for the
remaining 450 million people in rural areas
 An additional $26 billion per year is needed in
electricity generation and grids
In the New Policies Scenario, 90% of those without access in 2030 in sub-Saharan Africa are in
rural areas; electricity for all needs an acceleration in the deployment of decentralised systems

Conclusions
 Progress is being made towards the SDGs, but under current trends the goals on
climate change, air pollution and universal access will not be met
 There are strong synergies between renewable energy and energy efficiency that can
be harnessed to accelerate the clean energy transition
 Our strategy for sustainable energy shows that concerted action to address climate
change is fully compatible with global goals on universal access & air quality
 The Sustainable Development Scenario requires an additional 15% of investment and
profound changes in energy production & use
 Electrification & digitalisation are the future for many parts of the global energy system,
creating new opportunities but also risks that policy makers have to address
