Context
Electricity is increasingly important in the modern world, to date:
Electricity demand has been growing twice as fast as total energy demand
Investment in the power sector is larger than that in the oil and gas sector
The rise of solar PV and wind power is transforming electricity supply
Overall energy-related CO2 emissions are back on a rising trend in 2018
For the first time, the global population without access to electricity fell below 1 billion
Policy makers need well-grounded insights about different possible futures & how
they come about. The WEO provides two key scenarios:
New Policies Scenario
The Future is Electric Scenario was introduced to explore the implications of more
rapid electrification of end uses and the digitalization of the economy
Sustainable Development Scenario

Can we unlock a different energy future?
Global energy-related CO2 emissions
Coal plants make up one-third of CO2 emissions today and half are less than 15 years old;
policies are needed to support CCUS, efficient operations and technology innovation

Conclusions
The links between energy & geopolitics are strengthening & becoming more
complex, a major factor in the outlook for energy security
The rapid growth of electricity brings huge opportunities; but market designs need
to deliver both electricity and flexibility to keep the lights on
A comprehensive strategy to electrify end uses and decarbonise the power sector is
needed to achieve environmental goals
There is no single solution to turn emissions around: renewables, efficiency & a host
of innovative technologies, including storage, CCUS & hydrogen, are all required
The future pathway for energy is open: governments will determine where our
energy destiny lies
