From Watts Up With That?

For more than a decade, climate change skeptics have been sounding the alarm about the not-so-distant consequences of the global push for renewable energy, particularly solar panels. Their concerns, too often dismissed or overlooked, are now making headlines. A recent BBC podcast, “The Climate Question,” raises serious issues about the lifespan and end-of-life management of solar panels, issues that we have been echoing for years.

While they are being promoted around the world as a crucial weapon in reducing carbon emissions, solar panels only have a lifespan of up to 25 years,https://www.bbc.com/news/science-environment-65602519

writes Daniel Gordon of BBC Sounds. That’s a significant problem considering the sheer number of panels being installed worldwide. As Dr. Rong Deng states,

The world has installed more than one terawatt of solar capacity… there could be as many as 2.5 billion solar panels.https://www.bbc.com/news/science-environment-65602519

The truth is, solar panels aren’t eternal. And as they age, billions will eventually need to be disposed of and replaced, creating what Ute Collier, deputy director of the International Renewable Energy Agency, describes as a potential “waste mountain by 2050.” In response to this emerging issue, Ms. Collier is calling for “urgent government action.”

Despite the exciting boom period for solar panel installations, there’s a pressing need to grapple with this oncoming wave of waste.

By 2030, we think we’re going to have four million tonnes [of scrap] – which is still manageable – but by 2050, we could end up with more than 200 million tonnes globally,https://www.bbc.com/news/science-environment-65602519

warns Ms. Collier. To put it in perspective, that’s half the amount of plastic currently produced globally each year.

The challenge of recycling these discarded panels is even more daunting. Traditional recycling methods, while able to recover most of the aluminum and glass, struggle to extract and reclaim the more precious materials, like silver and copper. According to Mr. Nicolas Defrenne, over 60% of the value of solar panels is contained in just 3% of their weight. However, these materials are intertwined with other components, making them economically challenging to separate.

Moreover, there’s simply not enough infrastructure to handle this kind of recycling demand. And with the first generation of solar panels nearing the end of their usable life, the clock is ticking. “Now is the time to think about this,” stresses Ms. Collier.

Initiatives like ROSI, the world’s first factory fully dedicated to recycling solar panels, are emerging. These ventures, still in their infancy, provide hope that even if the onslaught of dubious solar farm installations continue, that it’s not too late to turn this potential eco-disaster around.

Even if one decides it is a good idea to transition away from fossil fuels, even if just to preserve them as resources for future generations, this story underscores the necessity for a balanced approach to our energy solutions – one that factors in not just immediate benefits, but also long-term environmental costs.

Duh….Nuclear needs to be in the mix.
