Energy investment remained at over USD 1.8 trillion in 2018. A rise in fossil fuel supply investment offset lower
power and stable efficiency spend. Despite the shift, power was the largest sector for the third year in a row.

Conclusions
• Energy investment stabilised in 2018 due to a bounce back in spending on oil,
gas & coal supply while low-carbon (supply & demand) investment stalled
• Company strategies are reacting to technological change & unprecedented
uncertainties by focusing on projects that deliver returns more quickly
• Approvals of new conventional oil & gas projects are falling short of what would
be needed to meet continued robust demand growth
• There are few signs of the major shift of capital towards efficiency, renewables &
innovative technologies that is needed to turn emissions around
• Investment & financing decisions are shaped by policies: today’s frameworks are
not yet fit to avoid multiple risks for the future
