3D RENDERING

800 watts an hour for 3D rendering. 19kWh per day. Average NFT is 38-48kWh, so 2-3 days of rendering = 1 NFT transaction.

T-SHIRT PRODUCTION & NFTS

It takes about 494 kWh to make just one cotton t-shirt. 200 cotton shirts would be 98,800 kWh, which equals energy consumption of the average American home in 8 years or 2,058 ETH transactions. (This does not include printing, shipping, etc for customized shirts). CO2 emissions from t-shirts: 2.1kg per shirt. 420kg per 200 shirts. 1 NFT transaction is 28kg CO2.

NFT TRANSACTIONS

Important to note that this is for a single transaction for an NFT. Memo Atkin analyzed ~1,800 NFTs and found, with all the transactions, which can include: Minting, Bids, Canceled Bids, Sales and Transfer of Ownership, that the average is: 340kWh and 211kg CO2. But again, this is still half the footprint of the cost of producing 200 cotton t-shirts.
