The International Renewable Energy Agency (IRENA) recently made a clarion call to the global community. In its 2023 outlook report, IRENA asserted that the international investment strategy for the energy transition is currently too heavily skewed towards a limited number of technologies and countries. IRENA emphasized the need for a more balanced distribution of investments across an array of technologies and nations.
According to the recent evaluation of the global response to the critical Paris accord target of keeping global warming within a 1.5-degree Celsius increase, the current trajectory of the energy transition is veering off course. With such a critical issue at stake, the role of diversified investment by both government bodies and private investors is more pivotal than ever.
However, this stance might invite discord among proponents of the energy transition. Typically, environmental organizations encourage governments to allocate available funding to the select few technologies considered to be most promising currently, as highlighted in this Nature report. Balancing these differing perspectives on investment strategy will be a significant challenge moving forward.
The IRENA report offers vital insights that help governments formulate scenarios on the necessary funding for meeting global transition targets. In 2022, the report showed that investment in renewable energy sources totalled $500 billion. Despite this impressive figure, it only represents approximately one-third of the average yearly investment required to adhere to the Paris accord.
Most of these investments were funnelled into two primary areas: solar photovoltaic and wind power. An astounding 95% of all investments were directed towards these technologies in the previous year. IRENA made a strong argument for diversification, stressing the urgent need for additional funding to flow into other energy transition technologies like biofuels, hydropower, and geothermal energy, as detailed by the International Energy Agency. The agency also emphasized the need to invest in sectors beyond electricity, such as heating and transportation.
Interestingly, IRENA’s analysis indicated that 75% of global investment in renewable sources between 2013 and 2020 originated from the private sector, as stated in their Financial Overview. Private capital naturally gravitates toward the technologies and countries perceived to have the least risk associated with them.
However, this risk-averse approach can lead to a geographical imbalance in renewable energy investments. As it stands, a significant portion of global renewable investments—85%—has ended up benefiting less than half of the world’s population in the past year.
To address this inequity, the report argued for public funding as an urgent necessity to invest in basic energy infrastructure in developing nations, backed by the World Bank’s stance on public investment. Public investment can also help spur growth in less mature technologies that are overlooked by risk-averse private investors.
This discrepancy in renewable investment mirrors the geographic concentration of energy transition progress, a trend that IRENA’s Director-General, Francesco La Camera, termed concerning. According to him, progress remains limited to a handful of countries and regions, thereby excluding nearly half of the global population, as explored in this PNAS research.
On top of this, IRENA highlights another critical aspect in its report: the role of innovation. The agency underlines the significance of research and development (R&D) in paving the way for novel, more efficient renewable technologies. Notably, R&D can play an instrumental role in identifying and scaling technologies that may currently be overlooked, thus contributing to the diversification IRENA advocates for. It can also help address the critical challenges of storage and distribution, which are vital components of a reliable and resilient renewable energy grid.
Also noteworthy is the potential of emerging technologies such as hydrogen and carbon capture, utilization, and storage (CCUS). These solutions hold promise for high-emission sectors that have traditionally been difficult to decarbonize, such as heavy industry and aviation. Fostering innovation in these areas through increased R&D investment could have profound implications for the energy transition.
Additionally, IRENA’s report underscores the importance of economic and policy tools in steering investment. Instruments such as carbon pricing, subsidies for renewable energy, and regulations promoting energy efficiency can create a conducive environment for investment in diverse technologies and regions. In fact, such strategies have already proven successful in various contexts. For instance, feed-in tariffs and power purchase agreements have been instrumental in promoting the growth of wind and solar power across the globe.
Lastly, the role of international cooperation cannot be understated. Shared research, technology transfer, and financial support from developed to developing nations can significantly contribute to the spread of renewable technologies worldwide. Joint efforts can help overcome the investment and technology disparities among countries, fostering a truly global energy transition.
In conclusion, IRENA’s recent report underscores the crucial need for a diversified investment strategy for the energy transition. The world must take collective and inclusive action to shift from fossil fuels to renewable energy sources. Striving towards this goal, we need to broaden our focus to include a wider array of technologies and regions. It is only through this holistic and inclusive approach that we can truly hope to meet our global warming targets and build a sustainable future. Diversifying investment, fostering innovation, utilizing economic and policy tools, and enhancing international cooperation are key to getting the energy transition back on track. IRENA’s call to action serves as a crucial reminder of the concerted efforts required to address this monumental challenge. Our shared future depends on our collective ability to respond effectively to this call.
