This case study describes the design, supply, and installation of a hybrid solar power system with lithium battery storage by GadgetroniX for the UNHCR Distribution Center in Arusha, Tanzania, to ensure uninterrupted power for logistics and administrative operations.

A case study detailing the design and installation of an off-grid solar power system upgrade by GadgetroniX for the Serengeti Mara River Camp in Tanzania, featuring expanded solar capacity and lithium energy storage.

This briefing by RMI argues that PJM can address rapid load growth and high energy costs by streamlining the interconnection process for Energy Resource Interconnection Service (ERIS) resources. Based on analysis by Aurora Energy Research, the document asserts that energy-only resources, particularly wind and solar, are financially viable without capacity revenues and could provide significant cost savings to ratepayers if the interconnection pathway is reformed to prioritize speed and minimal network upgrades.

In 2025, record solar and wind growth met 99% of global electricity demand increases, causing fossil fuel generation to decline for the first time since 2020. Renewables surpassed coal as a share of global electricity generation for the first time in a century, reaching 33.8%.

The global electricity sector has transitioned from fossil-fuelled growth to clean growth, with clean power meeting all global demand growth in 2025. This shift is driven largely by the plateauing of fossil generation in China and the rapid scale-up of solar and wind power. Battery storage is now emerging as a critical technology to displace fossil fuels during non-daylight hours, particularly in high-solar regions.

This report by Ember analyzes global electricity demand and supply trends in 2025 and over the preceding two decades. It details the growth of low-carbon sources, specifically solar and wind, and the relative decline of fossil fuels, while noting the impact of weather and policy on national energy mixes.

This report provides a detailed analysis of the power sectors of the world's seven largest electricity markets in 2025: China, the United States, the European Union, India, Russia, Japan, and Brazil. These regions collectively represent 72% of global electricity demand. The document examines trends in generation mix, demand growth, carbon intensity, and emissions, highlighting a global shift toward wind and solar, though the pace and drivers vary significantly by region.

A report by Ember analyzing how the expansion of wind and solar capacity in Britain mitigated the economic impact of a fossil fuel crisis in early 2026, which was triggered by conflict in the Middle East.

This report evaluates the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) scheme, specifically Components A and C-FLS, which promote decentralized solar power plants (1–10 MW) on farmers' land to improve irrigation and reduce state power subsidies. While the economic case is strong, the report identifies governance, market, and structural barriers that have led to gradual progress, and provides recommendations for a post-2026 scheme architecture.

This report by Ember examines how the growth of solar power in South Asia is reducing the power sector's exposure to global fossil fuel price shocks, while highlighting that broader fossil fuel dependence persists in transport and industry. The authors argue that further reductions in fuel imports require the electrification of non-power sectors and enhanced regional grid integration, with India serving as a central hub for electricity trade.

A briefing by Zero Carbon Analytics analyzing how Vietnam's investment in solar power mitigates the economic impact of soaring fossil fuel prices caused by a conflict in Iran, while warning that continued reliance on coal and LNG imports increases future vulnerability to price shocks.

In 2025, the European Union's power sector reached a tipping point as wind and solar generation surpassed fossil fuels for the first time, accounting for 30.1% of electricity. While solar generation hit record highs and coal reached a historic low, gas power saw a slight increase, though it remained below pre-crisis levels.

The European Electricity Review 2026 by Ember analyzes electricity generation and demand across the EU-27 for 2025. The report highlights a historic tipping point where wind and solar combined to produce more electricity than all fossil fuel sources for the first time, while coal reached a new historic low. Despite this progress, the EU remains dependent on imported gas, which drove up electricity prices and import costs in 2025. The report emphasizes the role of battery storage in reducing gas reliance and curtailment of clean power.

This end-of-year commentary by Ember synthesises key findings from 2025 regarding the global energy transition, highlighting how solar and wind power have begun to outpace global electricity demand growth and reshape energy dynamics through the rise of "electrotech" and battery storage.

This report by Ember examines the energy transitions of Viet Nam, Indonesia, and the Philippines, which together drive nearly 60% of ASEAN's power demand and emissions. While these nations remain heavily reliant on coal, they are pivoting toward clean energy through ambitious national targets, market reforms, and increasing foreign investment, particularly in solar and wind power.

The Q3 Global Power Report by Ember analyzes global electricity generation for the first three quarters of 2025, highlighting a structural shift where clean power growth meets and exceeds electricity demand, leading to a forecast of no fossil fuel growth for the full year of 2025.

India is generally on track to meet its National Electricity Plan (NEP) 2032 capacity mix, driven by record solar expansion and a strong pipeline of coal and pumped hydro projects. While solar, hydro, and coal are well-positioned, onshore wind requires significant acceleration, and nuclear capacity is likely to fall short of targets due to long lead times and a limited near-term pipeline.

In the first half of 2025, global solar and wind generation grew sufficiently to exceed total electricity demand growth, resulting in renewables overtaking coal in the global electricity mix for the first time. While global power sector CO2 emissions fell marginally by 0.2%, results varied by region, with emissions decreasing in China and India but increasing in the US and EU.

The report 'Global Electricity Mid-Year Insights 2025' by Ember analyzes global electricity generation from January to June 2025. It finds that solar and wind growth exceeded global demand growth, leading to renewables overtaking coal's share in the global electricity mix for the first time on record and causing power sector CO2 emissions to plateau.

This policy brief from the Stockholm Environment Institute provides a snapshot of the wind and solar energy landscape in Colombia as of early 2025, detailing capacity growth, approved projects, and the financial and social challenges facing the energy transition.
