Last year saw an 8% drop in global energy investments to $1.8 trillion in 2015, down from $2 trillion in 2014, according to IEA’s World Energy Investment 2016 report.

According to research, the energy system is undergoing a broad reorientation toward low-carbon energy and efficiency.

China was the world’s largest energy investor last year with energy supply spending of $315 billion. This was due to robust efforts in building up low-carbon generation and electricity networks, as well as implementing energy efficiency policies, according to the Paris-based agency.
