How Sustainable is PV solar power?
How Sustainable is PV solar power?
It's generally assumed that it only takes a few years before solar panels have generated as much energy as it took to make them, resulting in very low greenhouse gas emissions compared to conventional grid electricity. However, a more critical analysis shows that the cumulative energy and CO2 balance of the industry is negative, meaning that solar PV has actually increased energy use and greenhouse gas emissions instead of lowering them. The problem is that we use and produce solar panels in the wrong places. By carefully selecting the location of both manufacturing and installation, the po...

Knowing where our materials come from, what’s in them, how they were made, and how long they’ll persist in the environment beyond the life of a building gives us greater control over our projects and product decisions. This knowledge allows architects to set priorities and identify opportunities for innovation.
