Renewables 2023 Global Status Report - Energy Supply Summary

Core Content

The Renewables 2023 Global Status Report - Energy Supply Module provides a comprehensive analysis of the global renewable energy landscape, highlighting both progress and challenges in transitioning to a sustainable energy system. It is part of a five-piece collection that includes modules on energy demand sectors and systems, aiming to offer a systemic global overview of the current uptake of renewables.

The report underscores the importance of renewable energy in addressing global energy crises, climate change, and the need for a stable and reliable energy supply. It emphasizes that while renewable power has seen record growth in 2022, this growth is still insufficient to meet global energy needs and that critical bottlenecks such as slow permitting and inadequate grid infrastructure remain significant obstacles.

Main Points

• Renewable Power Growth: In 2022, renewable power experienced record-breaking growth, but it still lags behind the necessary pace to support a sustainable and prosperous global economy.
• Energy Supply Crisis: The 2021-2022 global energy crisis, driven by post-pandemic economic recovery and the Russian invasion of Ukraine, has increased the focus on renewable energy as a secure and stable alternative.
• Policy and Investment: Governments and institutions have intensified their support for renewables through policies and investments. Examples include the US Inflation Reduction Act (IRA) and the EU's REPowerEU.
• Key Renewable Technologies: The report covers various renewable technologies such as bioenergy, geothermal, heat pumps, hydrogen, hydropower, solar PV, concentrated solar power (CSP), solar thermal heating, and wind power.
• Infrastructure and Manufacturing: The report stresses the need for stronger infrastructure and manufacturing capabilities to support the expansion of renewable energy, including supply chain security and skilled labor development.
• Challenges: Despite progress, the report identifies challenges such as slow permitting processes, inadequate grid infrastructure, and limited renewable heat and fuel development.

Key Information

Renewable Energy Sources and Their Contributions

• Renewable Power: Over 1 terawatt of renewable power capacity is waiting to be constructed or connected to the grid.
• Renewable Heat and Fuels: These account for nearly 80% of global energy supply but are still heavily reliant on fossil fuels.
• Solar PV: The global capacity and additions have grown significantly since 2012, with the top 10 countries leading the expansion.
• Wind Power: Wind power capacity and additions have also seen substantial growth, with major contributors from GWEC, WindEurope, and WWEA.
• Bioenergy: It remains a significant contributor to total final energy consumption, with ethanol, biodiesel, and HVO/HEFA fuel production increasing over the years.
• Geothermal: The report includes data on geothermal power and direct use, with the top 10 countries and the rest of the world contributing to global capacity.
• Hydrogen: Several countries have developed hydrogen strategies and roadmaps, showing increasing interest in this emerging sector.

Global Stakeholders and Partners

• Renewable Energy Organizations: REN21 collaborates with numerous industry associations, such as the Global Wind Energy Council (GWEC), SolarPower Europe (SPE), and International Hydropower Association (IHA).
• Science and Academia: The report includes contributions from academic institutions and research bodies like NREL, IIASA, and TERI.
• Government Entities: Several countries, including Germany, India, and South Africa, are highlighted for their renewable energy policies and initiatives.
• NGOs and International Bodies: Key organizations such as Greenpeace International, 350.org, and the UN Environment Programme are involved in the report's development and dissemination.

Data and Methodology

• The report is based on crowd-sourced and peer-reviewed data, collected from a global network of experts.
• It includes data collection and validation processes, as well as methodological notes and glossaries to ensure transparency and accuracy.
• The data pack provides detailed reference tables and figures, which can be accessed through the REN21 website.

Challenges and Opportunities

• Permitting and Grid Infrastructure: These are critical bottlenecks in the deployment of renewable energy.
• Standardisation of Sustainability: There is a need for standardisation in the hydropower sector to ensure sustainable development.
• Investment Gaps: The report highlights the need for increased investment in renewable energy, especially in climate change mitigation scenarios, to reach the required levels by 2030.

Conclusion

The Renewables 2023 Global Status Report - Energy Supply Module is a crucial resource for policymakers, industry leaders, and stakeholders aiming to drive the global transition to renewable energy. It outlines the current state of renewable energy development, identifies key challenges, and provides actionable insights for achieving a sustainable and resilient energy future.
