    Just FYI: The claim that solar panels barely break even in regards of carbon is misinformation:

    Indeed, the solar panels exported from China in 2024 will have paid off their “carbon debt” within an average of just four months, according to detailed recent analysis for Carbon Brief. Manufacturing the solar panels will have added some 72m tonnes of CO2 (MtCO2) to China’s emissions in 2024, but will cut them overseas by 203MtCO2 per year, the analysis found. In total, these solar panels will save some 4.1GtCO2 over their lifetimes, paying off the upfront “carbon debt” some 57 times over. Looked at another way, the lifecycle emissions of solar power are far lower than those of fossil fuels, as shown in the chart below, which is based on UN data published in 2021.

    And since most solar panels are produced in China and China is rapidly building clean energy, that will also go down further in the future. Solar is great.
