Energy supply in the future will place major
challenges on the infrastructure
Three global megatrends in the energy sector
Demographic dynamics
Resource scarcity
Environmental focus
Population growth:
7.5 bn in 2020 (+1.1 bn)
Power consumption:
+5.2% p.a. in emerging
regions and 1.4% in
developed world
Geopolitics:
70% of world oil and gas
supplies only in a few
countries
Fuel diversity:
100% increase in oil prices
over last 2 years accelerates
shift to broader fuel mix
Global emissions:
40% increase in air pollution over past 20 years
Megacities (>10 million):
22 new megacities in 2015

Climate change:
Global warming limited to
an average increase of
2 degrees Celsius
