Silicon cost per watt down 96% over last two decades
"In 2004, we deployed 1,044 MW of solar power, using just over 16,000 kg of silicon globally. According to Bloomberg, 268 GW of solar was deployed in 2022, which is over 250 times more capacity than what was deployed in 2004. At 2.2 grams per watt, the 268 GW used approximately 590,000 kg of silicon, or 35 times more silicon than was used in 2004."
I believe these figures should be 16,000 metric tons and 590,000 metric tons rather than kilograms.
