Why Are NFTs Bad For The Environment

How is cryptocurrency bad for the environment?

Bitcoins need enormous quantities of energy. Each transaction requires approximately 2,100 kilowatt-hours, which is equal to what the average US household consumes in two months.


Furthermore, Bitcoin mining consumes 91 terawatt-hours of electricity each year, which is approximately seven times the amount required to power Google searches worldwide and accounts for about 0.5% of global electricity use. Finland, Sweden, the Netherlands, and Greece use nearly the same amount of energy in a year. Furthermore, crypto mining threatens some countries’ frail electricity infrastructures, which struggle to handle the power-intensive process. Several cities in Iran, Kazakhstan, and Kosovo have frequently experienced protracted blackouts as a result of Bitcoin mining activities.

According to calculations, Bitcoin emits approximately 57 million tons of CO2 each year. Basically nearly half a ton of CO2 for each transaction. Planting 300 million trees would be required to offset such massive emissions. Furthermore, according to a 2018 study published in Nature Global Change, the use of Bitcoin alone might push the world past the 2-degree Celsius warming threshold for climate catastrophe in 16 to 22 years.

Why are people against NFTs?

One of the most common criticisms leveled about NFTs is their carbon footprint. If you don’t know the context, it may appear a little foolish.


NFTs are fundamentally tokens kept on a blockchain. While they can be kept on any blockchain that supports them, the vast majority are on the Ethereum blockchain.

There is nothing wrong with Ethereum. After all, there’s a reason why its native cryptocurrency, Ether, is the market’s second-largest cryptocurrency, trailing only Bitcoin. But it’s all good until you consider the environmental consequence.

How are NFTs affecting the economy?

NFTs provide new options for businesses to manage and sell items in digital ecosystems. Many believe them to be significant economic innovations since they allow creatives everywhere in the world to share and get compensated for their work.


This will most certainly encourage the creation of more NFTs, which customers throughout the world have expressed a strong desire to purchase.

NFTs are also expected to challenge current concepts of copyright and ownership. Transactions with NFTs are permanently recorded on a digital ledger, allowing you to determine who made a purchase, when it occurred, and how much was paid.

how much electricity does an nFT use?

An NFT transaction uses around 48.14 kWh of energy. This is roughly the amount of power used by an average American family in a day.
NFT transactions are time-consuming. There is a lot of activity from all participants, including the buyer, vendor, and the website hosting the event.

The assignment of new ownership to a component of a digital asset will be the result of an NFT transaction. And in order to do so, you must go through the time-consuming process of saving the new ownership information on the blockchain.

What’s the most environmentally friendly crypto?

Environmentalists believe that bitcoin “mining” consumes an alarming quantity of fossil fuels.

However, there are alternative, eco-friendly cryptocurrencies that cause less harm to the environment.

These could help to alleviate concerns about cryptocurrency and the environment.

Smaller currencies may appear to have a lesser carbon footprint, although this is generally due to fewer transactions. However, there are digital assets that are more energy efficient, which implies they have a lower environmental impact.

According to TRG Datacenters research, these coins appear to be the most efficient in terms of energy requirements:

  • IOTA (0.00011kWh)
  • XRP (0.0079 kWh)
  • Chia (0.023kWh)


According to TRG Datacenters, chia is an excellent example of a sustainable coin crypto that has been built to be less energy hungry.

chia’s “farming” technique uses hard drives – a notion called as proof of space – rather than bitcoin’s mining, proof-of-work approach, which relies on computer CPUs.

Important information:

  • Chia coins can be farmed on a laptop or desktop computer hard drives, and spare space can be used for “plots.”
  • Once the software has been fully downloaded, your computer will plot the plots for you and begin cultivating chia.
  • Because it does not require as much electricity as mining cryptocurrency, this method makes it easier for home consumers to cultivate chia.
  • However, some critics argue that it isn’t as environmentally benign as it promises because it has resulted in a substantial increase in demand for computer technology and rising levels of e-waste.


IOTA employs “Tangle,” an alternative technique that does not require miners.

It is maintained by smaller devices and hence requires less energy.


Cardano, unlike other cryptocurrencies, employs a proof-of-stake system known as Ouroboros. This compels users to acquire tokens in order to join the network, resulting in huge energy savings.

Important information about Cardano:

  • It was created by Charles Hoskinson, co-founder of Ethereum, the second-largest cryptocurrency after bitcoin, and can perform 1,000 transactions per second, compared to up to seven with bitcoin.
  • Ouroboros is the first peer-reviewed blockchain-based protocol, which means it can be scaled to global demand without sacrificing sustainability or security, according to Cardano.
  • Cardano is likely the most well-known of the green cryptos, and it was the fifth-largest cryptocurrency at the time of writing.
  • TRG Datacenters calculated that its energy consumption is 0.5479 kWh.
