Commentary argues solar power carries a heavy mining waste burden
The piece argues that solar power has environmental costs beyond making electricity.
It focuses on photovoltaic panels, which generate electricity from sunlight, and says their output varies with the weather and time of day.
The author says balancing that supply requires storage, backup power and more grid equipment.
Those systems, the piece argues, need large amounts of materials, especially copper.
It links copper mining to toxic tailings, the waste left after ore is processed, and estimates a large waste burden for solar power.
The author compares this waste with waste from nuclear power and argues that the comparison is not as simple as it may seem.
The piece gives no policy response or next step.
An Inside Paradeplatz commentary argues that solar power has a substantial mining-waste burden because of its demand for copper and other materials.
It says photovoltaic power needs storage, backup generation and grid upgrades because production is intermittent.
The commentary estimates that solar power causes at least 400 million tonnes of toxic mining sludge each year.
It claims that each solar module requires about 1.5 kilograms of copper, associated with more than 200 kilograms of mine tailings.
The article compares mining waste from solar power with nuclear waste and argues that the toxic waste amounts per unit of electricity are similar.
- Who
- The commentary is by Inside Paradeplatz; the author is not named in the article.
- What
- It argues that solar power carries a large mining-waste burden, especially from copper production.
- When
- Published on 11 October 2026.
- Where
- The article discusses photovoltaic power and mining waste globally.
- Why
- It argues that solar power’s low power density and intermittent production require extensive materials, storage, backup generation and grid infrastructure.
This story does not have two clearly opposing sides.
The problem is that copper mining is the undisputed world champion in the production of toxic waste
The photovoltaic toxic doses remain until the end of time
