NREL Unveils Ultraefficient Silicon Carbide Power Module
NREL researchers have developed the world’s fastest, low-cost, ultraefficient silicon carbide power module, named ULIS, which promises major improvements in power electronics for grid modernization and renewable integration. The innovation is expected to reduce system costs and boost efficiency for clean energy systems [1].
Energy Storing Efficient Air Conditioner Set to Strengthen Grid Resilience
NREL, in partnership with Blue Frontier Inc., introduced a new air conditioning technology that integrates built-in energy storage, helping lower building electricity bills while reducing grid demand during peak periods. This advance could support widespread grid modernization and energy efficiency in commercial and residential buildings [1].
US Federal Policy Shifts Stall New Wind and Solar Projects
Executive orders issued in 2025 have paused permitting for wind and solar projects on federal lands, suspended offshore wind leasing, and prioritized fossil fuel development, creating significant regulatory uncertainty and delays for renewable energy developers. These changes have reshaped investment strategies and project timelines across the US clean energy sector [4].
US Renewable Energy Investment Plummets Amid Policy Turbulence
BloombergNEF reports that US renewable energy investment dropped $20.5 billion in the first half of 2025, marking a 36% decline from late 2024, driven by the removal of federal tax incentives and increased tariffs. The downturn has led to widespread project cancellations, especially in clean tech manufacturing, while tariffs have raised solar and battery storage costs by up to 30% [3].
Battery Storage Capacity Set to Double in US by 2026
EIA projects US utility-scale battery storage will grow from 29 GW in 2025 to 65.7 GW by the end of 2026, with Texas leading new deployments. Despite headwinds for wind and solar, grid storage incentives remain intact through 2033, supporting robust expansion in energy storage nationwide [3].
International Trade Commission Investigates Solar Imports from Asia
The US International Trade Commission has voted unanimously to investigate solar cells and panels imported from India, Indonesia, and Laos for alleged unfair trade practices. This move signals continued scrutiny of global supply chains and may impact domestic solar deployment costs and timelines [3].
Japan Accelerates Rail Electrification With Renewables
Resource-scarce Japan is increasingly powering its trains with renewable energy, advancing national decarbonization and energy security goals. This initiative underscores the global trend of integrating renewables into transportation infrastructure [7].
