テキサス州電気信頼性評議会（ERCOT）が管轄する電力市場において、今年初めて太陽光発電による発電量が石炭火力を上回る見通しとなった。この変化は、太陽光発電の開発業者が急速に供給能力を拡大する一方、石炭火力発電所の新規建設が皆無であることから起きている。連邦政府の予測では、2026年の太陽光発電量は780億キロワット時となり、石炭火力の600億キロワット時を上回るとされている。
テキサス州電気信頼性評議会（ERCOT）は、同州の競争的電力市場を運営している。太陽光発電の月間発電量は、すでに昨年3月から8月にかけて石炭火力を上回っている。米国エネルギー省エネルギー情報局によると、今年は3月から12月にかけて太陽光が石炭をリードすると予測されている。

Tesla Energy Ventures has received approval from the UK energy regulator Ofgem to supply electricity to households and businesses across England, Scotland, and Wales. The licence, effective from March 11, 2026, allows the company to replicate its Texas electricity model despite public opposition linked to Elon Musk's political activities. This marks a key step in Tesla's expansion into the UK energy market after years of building infrastructure.
Two new reports from the International Energy Agency and Ember highlight 2025 as a pivotal year for renewable energy, with solar power leading growth and renewables surpassing coal in global electricity generation for the first time in over a century. This progress occurred amid a war in Iran that disrupted 20 percent of the world's oil and liquefied natural gas supplies. The analyses point to an emerging 'age of electricity' driven by renewables.

The Unidad de Planeación Minero Energética (UPME) reported that in 2025 solar energy generated 4,473.8 GWh, surpassing coal by 25% at 3,564.2 GWh. President Gustavo Petro highlighted a 1,650% growth under his government. UPME emphasizes the sun's relevant role in the national grid.
The U.S. electric grid loses about 5% of generated electricity during transmission, highlighting the need for better storage and delivery systems to support clean energy. A recent overview outlines seven key innovations addressing these challenges across generation, storage, transmission, and demand.

Utah became the first state to legalize plug-in solar panels that connect directly to home outlets, inspiring similar legislation in 30 other states and the District of Columbia. Republican state Representative Raymond Ward sponsored the unanimous bill last year after learning about Europe's balcony solar trend. The technology promises affordable solar power without costly rooftop installations.
Homeowners are shifting from exporting excess solar power to the grid toward storing it in batteries due to changing net metering rules and climbing electricity prices. This trend favors systems that combine solar panels with batteries and electric vehicles for better energy management. Experts highlight the potential for integrated whole-home electrification solutions.
