Investment Rating - The report does not explicitly provide an investment rating for the solar and wind energy industry Core Insights - Trade in solar and wind energy technologies is experiencing significant growth, yet the pace is insufficient to replace fossil fuel-based energy generation. Developing countries are primarily net exporters of raw materials while being net importers of manufactured goods in the energy value chains [3][12] - High trade costs along solar and wind energy technology value chains hinder the affordability of renewable energy technologies and limit industrialization opportunities. Average tariffs on green energy goods in developing countries range from 2.5% in Asia and Oceania to 7.1% in Africa, with non-tariff measures adding additional costs of 0.4%-0.7% [4][58] - Lowering tariffs on intermediate goods can facilitate the entry of developing countries into the assembly stage of green energy technologies, with current tariffs on intermediate products in Africa reaching up to 8.1% [5][62] - Regional integration can be enhanced by addressing both tariffs and non-tariff barriers, as intra-African tariffs are nearly double those in other developing regions [6][63] - The increasing use of temporary trade defense measures on green energy goods, particularly for Asian traders, suggests a need for improved trade remedy mechanisms [7][70] - Developed countries should reassess their trade, investment, and aid policies towards developing countries to align with global energy transition goals [8] Summary by Sections Tackling Climate Change and Energy Access - Renewable energy is essential for addressing climate change and energy poverty, with the potential to provide electricity to 685 million people lacking access [10][19] - The urgency of reducing greenhouse gas emissions is critical, with a target to peak emissions before 2025 and reduce them by 43% by 2030 [16][17] Solar and Wind Driving the Energy Transition - Despite rapid growth, fossil fuels still accounted for 82% of global energy consumption in 2022, with renewable energy comprising only 5% [24][25] - Solar and wind energy are leading the transformation of the electricity sector, with renewable power capacity growing from 21% in 2000 to 43% in 2023 [27][28] The Anatomy of Green Energy Value Chains - The production of solar panels and wind turbines involves complex value chains with numerous inputs, including raw materials and intermediate products [40][41] New Technologies Following Historical Trade Patterns - Global trade in solar and wind energy goods exceeded US$ 1.5 trillion annually between 2020 and 2022, with significant trade values associated with final production stages [45][46] Trade Barriers Along Green Energy Value Chains - Developing countries face high tariffs on green energy goods, which can hinder their integration into global value chains. Average tariffs range from 2.5% to 7.1% across different regions [58][59] - Reducing trade barriers and compliance costs associated with non-tariff measures can enhance intra-regional trade, particularly in Africa and Latin America [65][66]

Investment Rating - The report indicates a challenging outlook for SDG investments, particularly in least developed countries (LDCs), where investments are expected to fall by over 25% [3][9][31]. Core Insights - International investment in SDG-relevant sectors, excluding renewable energy, has stalled since 2015, with foreign investors sponsoring only one-fifth of infrastructure projects in developing countries [2][4]. - Preliminary data for Q1 2024 shows an 11% decline in the number of projects compared to the 2023 average, although the total value of these projects increased by 7% due to large-scale projects [3][9]. - The distribution of international SDG investments remains uneven, with 18 developing economies not receiving any internationally financed SDG projects since 2015 [4][11]. - The Belt and Road Initiative (BRI) has become a key driver of SDG investments, particularly in Africa, where it accounts for a third of all investments in social infrastructure sectors [8][31]. Summary by Sections International Investment Trends - Since 2015, the total number of international projects in SDG-related sectors has grown by 25%, primarily driven by renewable energy projects [3][14]. - The average number of SDG-related projects increased by around 20% over the last decade, but investments in water and sanitation (WASH) have halved [4][14]. Regional Disparities - Africa has consistently attracted the fewest international projects related to the SDGs, despite having a higher share of SDG-related projects compared to total international projects [16][20]. - In Latin America and the Caribbean, the total number of SDG-related projects increased by 45%, driven by a threefold increase in renewable energy investments [16]. Role of Multilateral Development Banks (MDBs) - MDBs play a crucial role in attracting foreign private investment for infrastructure projects, participating in about 5% of all project finance deals aligned with the SDGs [7][26]. - MDBs are more involved in LDCs, contributing to nearly a quarter of international human capital projects and around one-fifth of infrastructure and renewable energy initiatives [26][28]. Major Investors and Projects - Top sponsors in the renewable energy sector include Enel (Italy), Engie (France), and EDP Energias (Portugal) [35][38]. - Significant projects include a $35 billion health sector development in Egypt and two green hydrogen power plants in Oman valued at $5 billion and $6 billion [9][31].
