Sunlight is already energy. Surely you mean something to do with energy conversion?
It's upsetting watching millions of acres of fertile land becoming essentially salted with heavy metals.
What is really effective at energy conversion is solar to thermal. We're talking 70% efficient, zero heavy metals. If we were to put panels on buildings, it's a crying shame that they are not zero heavy metal, vastly more efficient solar thermal.
- dalyons 3y agoWhat? How is the land getting “salted”? The small trace amounts of metals in the solar panels stay inside the solar panels. They don’t melt into the soil. And you just take the panels away when they reach EOL.
- acyou 3y agoThere are certainly not "small trace amounts" of heavy metals in solar panels. If they sit there for 100 years, the heavy metals will not stay put. Have you visited the rust belt? When cars reach EOL, they often don't get "taken away". Difficult to accept that people don't understand that bringing heavy metals up and putting them everywhere will ultimately result in leaching into groundwater and contamination of food and water.
