Cryptocurrencies and NFTs, digital artworks, use a lot of energy. To produce a single NFT, as much as 332 kWh of energy might be needed. That’s the equivalent of charging a smartphone 28,620 times. But there are sustainable alternatives. We’ve found 4 videos that explain what Clean NFTs are – and how all NFTs might soon become clean.
Digital artworks that live on a so-called proof-of-work blockchain network like Ethereum use a lot of energy. On proof-of-stake networks, like Solana and Tezos, creating an NFT requires much less energy. On Tezos, it’s as low as 0.0002 kWh, or the equivalent of 0.017 smartphone charges.
Minting three NFTs on Ethereum produces 415 kilos of carbon dioxide emissions. On the Tezos blockchain, the same NFTs would create 0.25 grams of carbon.
Energy can be produced from renewable sources like wind, solar, and hydropower, but most still come from fossil fuels, like coal.
The lower ecological impact is why NFTs on proof-of-stake networks are called Clean NFTs. Soon most NFTs can be more eco-friendly as Ethereum is planning a move to a proof-of-stake system.
