Hydroelectricity
Hydropower is the largest source of renewable energy today, but that could change soon
Hydro is currently the third largest source of power generation worldwide after coal and natural gas. In 2024, it generated around 4 500 terawatt-hours of electricity, or 14% of the global total.
More than 150 gigawatts (GW) of new hydro capacity is set to come online by the end of the decade, mostly in emerging and developing economies. As a result, electricity generation from hydropower is expected to increase by 7% between 2025 and 2030. However, its share in global electricity generation is poised to…

Ukraine’s Energy Security
A pre-winter assessment As Ukraine enters its fourth winter of war, ensuring that residents retain reliable access to heat and power is of the utmost importance. While Ukraine made strong strides in rebuilding and strengthening the resilience of its energy system this past spring and summer, the situation remains fragile, and the risk of huge disruptions and widespread destabilisation remains – particularly as Russia expands the scope and sophistication of its attacks.This analysis builds on the IEA’s September 2024 report, Ukraine’s Energy Security and the Coming Winter. It provides an update on the latest developments through October…

South Africa
Coal is the mainstay of the South African energy system, meeting around 70% of installed power generation capacity. The 2019 Integrated Resource Plan however sets out a long-term diversification of the power mix by 2030 and moves towards lightening the carbon footprint of the energy sector while meeting growing energy demand and ensuring a socio-economically just transition. While the options to diversify the country's electricity mix appear diverse, the affordability of electricity supply looms as a key concern and a potential constraint on diversification. The structure of consumption and of spending on electricity is skewed towards higher…

Wired for water: How electrification is transforming desalination
Wired for water: how electrification is transforming desalination The water-energy nexus Pressure on water resources is increasing worldwide and can be very acute at the local level. Rising consumption across sectors combined with population growth in already water-stressed regions is intensifying water scarcity. Desalination has long been developed to supply fresh water in the most affected areas, with significant implications for the energy system: energy use ranges from under 0.1% to as much as 15% of total final consumption, depending on national reliance. However, a shift is underway from thermal desalination technologies to electricity-driven systems as…

Stepping Up the Value Chain in Africa
Minerals, materials and manufacturing This report explores key opportunities for African countries to step up the value chain in the growing global market for energy technologies, identifying opportunities beyond a role centred around extraction and mining to one more focused on mineral beneficiation, material production and technology manufacturing. These opportunities would enable Africa to retain a greater share of the economic value generated across energy technology supply chains, and would simultaneously contribute to global efforts to enhance supply chain diversification and resilience.The economic benefits of the new energy economy are currently distributed very unevenly. Emerging markets and developing economies…

China’s Official Energy Finance in Emerging and Developing Economies Case 2. Southern power grid’s acquisition of Enel Peru distribution assets
Project overview and impact Latin America’s power systems face a growing need to modernise their electricity networks as clean energy deployment accelerates. While the region has seen a 25% increase in clean energy investment since 2015, grid spending has not kept pace, with less than USD 0.5 invested in networks and storage for every dollar spent on new generation. Strengthening distribution systems, especially in rapidly expanding urban areas, is essential to integrate more renewables. Peru is no exception. Although its electricity demand has grown steadily, network modernisation has lagged behind regional leaders, and the expansion of renewable capacity…

Cambodia
Cambodia’s electrification rate is the second-lowest among South East Asian countries. Cambodia plans to increase its power generation capacity by building hydropower and coal-fired plants by 2025, which can contribute to improve self-sufficiency of power supply.

H2U Program
The Uruguayan government, through Resolution No. 294/022, has launched the “H2U Program” to promote the development of green hydrogen as a key component in the country’s energy transition. The program, managed by the Ministry of Industry, Energy, and Mining, aims to leverage Uruguay’s renewable energy capabilities to produce green hydrogen, reduce greenhouse gas emissions, and support the decarbonization of the economy. Key goals include fostering innovation, attracting investments, building capacities, and enhancing international cooperation to position Uruguay as a leader in green hydrogen production and export

Southeast Asia Energy Outlook 2026
The Southeast Asia Energy Outlook 2026 is the seventh edition of this World Energy Outlook Special Report, making Southeast Asia by far the most regularly updated regional outlook compiled by the International Energy Agency (IEA). This reflects the dynamism of the region, as well as the importance of the IEA’s partnership with the eleven countries that make up the Association of Southeast Asian Nations (ASEAN) – Brunei Darussalam, Cambodia, Indonesia, Lao People’s Democratic Republic (Lao PDR), Malaysia, Myanmar, the Philippines, Singapore, Thailand, Timor-Leste (joined ASEAN in 2025) and Viet Nam.As energy security concerns move ever higher on…
