»Der Ausbau der Erneuerbaren Energien muss deutlich gesteigert werden, um die Pariser Klimaziele zu erreichen«

Studie der International Renewable Energy Agency, 9.4.2019 (engl. Originalfassung)

Although energy-related CO2 emission growth in 2014-2016 was flat, estimated emission levels increased by 1.4 % in 2017 to reach a historic high of 32.5 Gt (IEA, 2018a). Currently, the world is not nearly on course to meet the well below 2°C climate objective, and even further from attaining the aspirational target of limiting warming to 1.5°C.

Nevertheless, the power sector registered significant progress in some areas during 2017. The deployment of renewables reached record levels, in terms of both power generation and capacity addition. Record increases were also recorded in electromobility and other forms of electrification of end uses (such as heat pumps), while the use of modern bioenergy and solar thermal and geothermal energy also increased. Overall the share of renewables in total final energy consumption grew by an estimated 0.25%, to around 19% of TFEC, a new record.

Growth in renewable energy must nevertheless greatly accelerate. The world needs to increase the share of renewable energy in TFEC from 19% in 2017 to two-thirds by 2050. In parallel, the global economy needs to reduce energy intensity by 2.8% per year on average to 2050, compared with the 1.8% annual fall achieved in recent years. This would bring global energy consumption in 2050 to slightly below current levels despite significant population and economic growth over the period. Improvements in energy efficiency slowed in the last few years, causing carbon dioxide emissions to rise in 2017. A recent report by the International Energy Agency (IEA) nevertheless indicates progress and suggests that abundant opportunities exist to accelerate energy efficiency worldwide.
