We are going through what we might call the mother of all crises. The world has witnessed many oil crises in the past 50 years, such as the post-COVID-19 crisis and following geopolitical tensions.
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.
People who could afford to do it at that time realised that it was much cheaper and cost-effective and better for them in the long run to do a one-time investment in rooftop solar as opposed to keep paying high electricity bills from a grid that is also unreliable, said Nabiya Imran, an associate at Renewables First, a Pakistani thinktank.
The group points out, correctly, that the grid is designed for brief bursts of high demand; most of the time there's lots of capacity that goes unused. Utilize thinks that should change. The group argues that smarter ways to use that capacity already exist. Utilize name checks a number of those solutions, including battery storage, demand response, and virtual power plants, all of which have emerged en masse over the last decade, but remain under utilized.
"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."
With these arrangements sometimes called subscriptions or power purchase agreements (PPAs), a third party owns the panels and leases them back to the homeowner. But last summer, President Trump signed legislation that ended federal tax incentives that had cut at least 30% off the price of purchased panels. Similar incentives for leased panels remain.
The pioneering technology means one of the oldest forms of energy storage, hydropower, can be used to store and release renewable energy using even gentle slopes rather than the steep dam walls and mountains that are usually required. The design means the principles of hydropower could be used as a form of long duration energy storage in many more locations across the UK, and the world, than traditional hydropower dams. The projects could be quicker and cheaper to build too.
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.
We can keep tethering ourselves to volatile geopolitics, to fossil fuel prices we'll never control, and to an energy system built on instability and extraction-or we can choose the alternative that's right in front of us: harnessing the sun here at home on our own rooftops. By rapidly accelerating local solar in New York, we can build power right here in our communities, beyond the reach of coups, cartels, and commodity shocks.
Solar and wind power provided more electricity than coal and gas last year, leading a global trend, said think tank Ember. Solar and wind power outperformed fossil fuels in the European Union for the first time last year, a new high watermark on Europe's transition to green and autonomous energy. The two sources of energy generated 30 percent of EU electricity, compared with 29 percent for coal and gas, Ember, a global energy think tank, said on Thursday in its European Electricity Review.
