Integrating Solar and Wind in Southeast Asia
…exposes countries to volatile fuel prices, potential supply disruptions and rising emissions. At the same time, the region possesses vast and diverse renewable resource potential. Variable renewable energy (VRE) - solar and wind - are now among the most cost-competitive generation options and are playing an increasingly important role in the region’s power sector. VRE presents an opportunity for the region to meet rising demand, support energy security, affordability and climate goals. However, integrating higher shares of VRE can present technical and regulatory challenges that require changes to system operation and planning. This report provides a comprehensive assessment of the…

Ultra-fast charging batteries
GEVO 2026 - Chapter 8 New power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and therefore faster – charging systems. Advances in batteries and power electronics are improving EV performance Over the past decade, average EV battery pack energy density (Wh/kg) has increased by around 60%, while prices have fallen by roughly 75%. Moreover, in 2023, battery-related patents accounted for 40% of all energy-sector patents, suggesting that more developments are still to come. At the same time, new power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and…

Efficient Grid-Interactive Buildings in India
…and variable supply could jeopardise grid stability and increase system costs. EGIBs offer an important solution for optimising electricity use, reducing peak demand and enhancing system flexibility.Applying a structured framework, this report assesses India’s policy landscape and opportunities across efficiency, decarbonisation, smartness, resilience, materials and building-to-grid interaction. It concludes with recommendations for a comprehensive policy package that encompasses regulations, incentives and information. Scaling up the adoption of efficient grid-interactive buildings would enable India to align its fast-growing building stock with national climate goals and international commitments while lowering system costs and enhancing energy security.

Designing Energy Efficiency Policies to Enhance Affordability
…on designing energy efficiency policies that support affordability, particularly in the buildings sector.As part of this work, the IEA conducted a survey with G7 governments to better understand the obstacles they face. On the consumer side, major challenges include the landlord-tenant split incentive, high upfront costs and administrative complexity. On the supply side, governments identified skills shortages and difficulties in reaching underserved communities.The report analyses the affordability-focused energy efficiency policies of G7 countries. These include targeted financial support, simplified programme design, strong local delivery models, and better integration with workforce development. Embedding affordability into energy efficiency…

Vehicle-to-grid technology
…EV batteries become flexible assets for energy storage rather than mere loads to the grid. There are varying degrees of flexibility. With unidirectional smart charging (V1G), the charging power can be modulated to align electricity demand with generation profiles or to alleviate grid congestion. With vehicle-to-building (V2H/V2B), the EV can additionally discharge energy for use in a home or building, either to serve as a backup during power outages or to lower electricity bills by leveraging dynamic tariffs and increasing self-consumption of rooftop solar. Finally, V2G technology can push energy from the EV battery into the…
