The most consequential shift for anyone considering rooftop solar in 2026 is the expiration of Section 25D, the Residential Clean Energy Credit. That 30% credit, which was worth up to $9,000 on a $30,000 system, is no longer available for home solar installations. The One Big Beautiful Bill, signed July 4, 2025, accelerated the phase-out that the Inflation Reduction Act had originally extended through 2034.
"A more decentralized energy system, with a growing share of renewables and more market players, is structurally more resilient. Countries that invested in the energy transition are weathering this crisis with less economic damage, as they boost energy security, resilience and competitiveness."
Heritage is usually catalogued by what can be drawn, not by what changed temperature. In heat, buildings are learned first through skin, only later through sight. Generations learn, through their bodies, what works. Shade reduces glare and radiant heat. Air movement shifts perception by several degrees. Thick walls slow temperature swings.
We are making sure that we have renewable energy powering all of our datacentre footprint. We have 100% renewable power today that is powering all of Azure, and we're very proud to build that base and essentially stimulate renewable energy around the world and in the UK.
"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."
Spaces of light and darkness are conceived to enhance circulation and spatial directionality, as well as to highlight the colors, textures, and forms of specific architectural elements. That said, the impact of natural light on building facades reveals the need to develop strategies that support energy savings, improve the thermal and visual comfort of interior spaces, and promote the reduction of carbon emissions.
In Indra's Net of pearls and jewels, every gem reflects every other, a shimmering image of interdependence. This ancient Vedic metaphor for connection across the cosmos also illuminates what the environmental philosopher Glenn Albrecht first proposed in 2014as 'theSymbiocene': the era after the Anthropocene, in which human technologies take their cues from living systems and work in partnership rather than through dominance.
Photovoltaic (PV) solar energy represents a modular technology that can be manufactured in large-scale facilities, generating economies of scale, while also being adaptable to small-scale applications. From residential rooftop systems to large-scale power generation installations, photovoltaic solar energy has established itself as a cost-effective option for electricity production in many countries around the world.
The UC Berkeley Chancellor's Fund, the college's attempt at venture capital, has raised more than $250,000 from a single investor. Chancellor Rich Lyons has said he wants to blur the edge between the university and the region's startup ecosystem.

From the large industrial roofs and galleries of the 19th century to the contemporary atriums of museums and public buildings, glass has been a recurring material in shaping large and monumental interior spaces. More than a technological or engineering solution, these horizontal glazed planes introduce a distinct luminous quality: light that comes from above. Unlike lateral daylight entering through façades, zenithal light is more evenly distributed, reduces harsh shadows, and lends spaces a sense of continuity and openness that is difficult to achieve otherwise.
In the rolling hills of southeast Queensland, Australia, farmer and businessman Brent Finlay stands beneath turbines so tall they rival skyscrapers. "There's a lift inside that takes about 12 minutes to go from the bottom to the top," he said, pointing skyward. Forty-five of the giant turbines that now dot his property are part of the massive MacIntyre Wind Farm which will soon generate enough electricity to power 700,000 homes.
