This is an important first: 

1. Reuters are correctly calling it Bitcoin mining rather than "crypto mining", and explicitly linking it to reducing wasted energy. 

2. The article acknowledges that there has been an "increase of wasted energy" at the solar and wind generator with "billions of reais in losses to energy firms"

3. Reports that French company Engie is "looking at bitcoin mining ...at its new solar plant in Brazil to make the facility more profitable"

4. Acknowledges "having those systems would reduce curtailments that are hurting the economics of Assu Sol" (the solar and wind operator)

The ability of Bitcoin mining to accelerate green energy production through monetizing wasted wind and solar energy is well established in academic literature (since 2023) and among grid operators (since 2022) 

But this is marks a first time the mainstream media has explicitly acknowledged this.
