Solar panels don't last forever, and the problem already has a deadline: 2050

SAPO Notícias13 September 2026 at 12:00

Solar panels don't last forever and, within a few decades, the world will have to deal with millions of tonnes of photovoltaic equipment at the end of its useful life. This problem has a defined deadline: 2050 is the date pointed to as the moment when many of these pieces of equipment will reach the end of their useful life.

In this scenario, a team of researchers is working to find solutions for this environmental and waste management challenge. The article suggests that this team is focused on developing strategies to deal with the growing volume of solar panels that have reached the end of their useful life.

The context is one of accelerated growth of solar energy worldwide, which means that the number of panels that will reach the end of their useful life in the coming decades will be substantial. This represents a new sustainability challenge for the renewable energy sector.

Why this matters

This article is of interest to readers in Portugal and Brazil because it anticipates an environmental and economic problem that will directly affect consumers and governments who have invested in solar energy. Readers with solar panels installed or planning to install them need to know that there will be costs and decisions to make about their replacement in the coming decades. The article follows the massive expansion of the photovoltaic market in recent years, which now requires reflection on the complete life cycle of the technology.

AI Leaders Admit to Slowing Down More Advanced Models

Leaders of the largest artificial intelligence companies admit the need to slow down the development of the most advanced models given the growing security risks. Dario Amodei, CEO of Anthropic, proposed external evaluations with access similar to that of internal teams, a measure supported by Sam Altman and Elon Musk, clarifying that the proposal does not imply suspending model training, but creating time to test and protect the technology. Demis Hassabis, from Google DeepMind, considered the guidance correct, although he argues that the details still need to be defined. Any eventual coordination faces competitive and geopolitical obstacles, given that American companies compete for customers and market share among themselves and with Chinese groups, and it remains uncertain whether competition authorities would accept a coordinated slowdown.

Clucky is an app for people who need to "rise with the chickens" and has challenges to get them out of bed

The Clucky app was created for people who have difficulty waking up in the morning, offering an alternative to traditional alarm clocks that are often turned off and lead to going back to sleep. The app works through challenges and missions that the user needs to complete before being able to silence the morning alarm, thus encouraging a more active and conscious wake-up routine.

How Does Wi-Fi Go Through Walls? And Why Do Some Walls Destroy It?

Wi-Fi doesn't go through walls without consequences: the signal loses energy, is absorbed, reflected and deflected by the materials it encounters. Materials like concrete, brick, metal and even water absorb or block most of the signal, while plaster, wood and glass let it pass with less loss. The signal frequency also influences things: higher frequencies (like 5 GHz) offer more speed but attenuate more quickly through obstacles, while lower frequencies (2.4 GHz) penetrate better but with less bandwidth.
