IRENA’s most recent analysis on the macroeconomic impacts of renewable energy features in the report Perspectives for the Energy Transition: Investment Needs for a Low-carbon Energy System” analysing the global macroeconomic impacts of decarbonising the global energy sector in line with the Paris Agreement by 2050 with a large focus on renewables and energy efficiency.
The results show that decarbonising the energy sector increases global GDP in 2050 by around 0.8% compared to the Reference Case.
That is the equivalent of almost 19 trillion USD in increased economic activity between today and 2050, similar to the combined market capitalization of all the companies listed in the New York Stock Exchange.The increased economic growth is driven by the investment stimulus due to the capital-intensive nature of renewables and energy efficiency, and by enhanced pro-growth policies, in particular carbon pricing in which the income generated is fed back into the economy through lower income taxes, boosting consumption.
Improvements in welfare would go far beyond gains in GDP. IRENA analysis shows that the increase in welfare is close to 4%, compared to 0.8% improvement in GDP.The savings in health and environmental externalities far offset the costs of the energy transition.
