Investment Needs for a Low-Carbon Energy System

Perspectives for the Energy Transition
This is an extract, full report available as PDF download

Investment is the lifeblood of the global energy system. Individual decisions about how to direct capital to various energy projects – related to the collection, conversion, transport and consumption of energy resources – combine to shape global patterns of energy use and related emissions for decades to come. Government energy and climate policies seek to influence the scale and nature of investments across the economy, and long-term climate goals depend on their success. Understanding the energy investment landscape today and how it can evolve to meet decarbonisation goals are central elements of the energy transition. Around two-thirds of global greenhouse gas emissions stem from energy production and use, which puts the energy sector at the core of efforts to combat climate change. Against this backdrop, the German government has requested the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA) to shed light on the essential elements of an energy sector transition that would be consistent with limiting the rise in global temperature to well below 2°C, as set out in the Paris Agreement. The overarching objective of this study is to analyse the scale and scope of investments in low-carbon technologies in power generation, transport, buildings and industry (including heating and cooling) that are needed to facilitate such a transition in a cost-effective manner, while also working towards other policy goals. The findings of this report will inform G20 work on energy and climate in the context of the 2017 German G20 presidency.
