Today’s energy context
Mixed signals about the pace & direction of change in global energy:
Oil markets are entering a period of renewed uncertainty & volatility
Natural gas is on the rise: China’s rapid demand growth is erasing talk of a ‘gas glut’
Solar PV has the momentum while other key technologies & efficiency policies need a push
Our assessment points to energy-related CO2 emissions reaching a historic high in 2018
For the first time, the global population without access to electricity fell below 1 billion
Electricity is carrying great expectations, but questions remain over the extent of its
reach in meeting demand & how the power systems of the future will operate
Policy makers need well-grounded insights about different possible futures & how
they come about. The WEO provides two key scenarios:
New Policies Scenario Sustainable Development Scenario

The CO2 emissions trajectory to 2040 in the SDS is at the lower end of a range

Progress in electricity access is seen in all world regions,
but sub-Saharan Africa lags behind
The world population without electricity access fell below 1 billion in 2017, led by India;
but despite recent progress, efforts in sub-Saharan Africa need to redouble

Synergies between energy access and GHG mitigation
Higher CO2 emissions from increased fossil fuel consumption for access are more than
offset by a reduction in other GHGs from avoided traditional use of biomass

Electricity consumption in urban municipal wastewater treatment facilities in 2030
Impact on energy demand from meeting SDG 6 could be significant, but if right policies &
technology are put in place the wastewater sector can become a net energy producer

Conclusions
Energy-related CO2 emissions continue to rise and will hit record highs in 2018
Progress is being made towards the SDGs, but under current trends goals on climate
change, air pollution and universal access will not be met
Our strategy for sustainable energy shows that concerted action to address climate
change is fully compatible with global goals on universal access & air quality
There is no single solution to turn emissions around: renewables, efficiency & a host
of innovative technologies, including storage, CCUS & hydrogen, are all required
Energy requires water, but the integrated SDS has lower withdrawals than any other
scenario
