In This post, we will discuss The Impact Cryptocurrencies Have on The Environment
There are a lot of things that contribute to climate change, like fossil fuels, farming, and industrial pollution. Cryptocurrency has become a big part of the conversation in the last few years, though.
It takes a lot of energy to mine, especially Bitcoin mining, and the race to build the biggest mining rig makes more electronic waste than you could ever imagine.
How much money does cryptocurrency use up? No, it doesn’t. Mining and using crypto doesn’t cause climate change. What we know so far:

How Much Energy Does It Take To Make A Lot Of Energy?
Cryptocurrency is bad for the environment because it uses a lot of electricity for the mining process, which is how new digital coins are made. Coins like Bitcoin and other types of cryptocurrency all have to be mined in order to work.
But since Bitcoin came out, it has become more and more difficult to make new units of currency through mining. This was done by design because the currency was limited to 21 million units. The more units that were made, the fewer units there were to mine, and the more computational power it took to make new ones.
People are using more electricity to mine what’s left because of the preprogrammed scarcity and the chance to make money. One Bitcoin is worth about $42,000 right now, and the reward for mining a new block is 6.25 Bitcoin.
The Cambridge Bitcoin Electricity Consumption Index says that some countries, like the Netherlands and Pakistan, use more electricity each year to mine Bitcoin than the whole world does.
People are worried about how much CO2 the power plants that provide the energy are thought to make. Besides mining, it takes a lot of power to do things like buying and selling bitcoins.
One transaction is estimated to use 2,292.5 kilowatt-hours of electricity, enough to power a typical US home for more than 78 days.
It may seem like electricity is a clean source of energy, but many countries use fossil fuels to make it. This adds carbon dioxide to the atmosphere, which makes it more difficult for the Earth to stay warm and cool.
According to the University of Cambridge, the United States is home to about a third of the Bitcoin mining operations in the world. It also generates about 60% of its electricity from fossil fuels.
It also has to do with the amount of physical electronic waste. It takes things like laptops and graphics cards, as well as ASIC rigs made just for mining, to get money.
People upgrade and throw away old computers all the time because more computing power gives them an advantage in the race to mine more coins. This creates up to 30,000 tonnes of electronic waste each year.
The Impact Cryptocurrencies Have on The Environment
Many people might say that cryptocurrencies are the best thing that could happen to our world. Is it worth it to be able to move away from institutions like banks?
Cryptocurrencies might surprise you to learn that they waste so much electricity. Do they?
People who mine for cryptocurrency, especially Bitcoin, use a lot of electricity to keep running the number sequences that they need to keep going. There is always a race to find the most coins, so you can imagine that these machines are always running.
In the beginning, Bitcoin had a limit of 21 million BTC coins. There are fewer and fewer BTC coins to be mined as the years go by and more and more miners join the race. People who mine coins will need a lot more powerful software and a lot more electricity to do it.
According to an estimate, cryptocurrency mining emits less than 100 million tonnes of CO2. For comparison, a country like Germany or Italy would make about as much greenhouse gas like this.
In addition, research shows that most of this carbon dioxide comes from the United States since most of these mines are in the United States, which is where most of the carbon dioxide comes from.
Why Does Crypto Use So Much Energy?
Digital currencies were made to be hard to mine and take a lot of computing power to make so no one person or group could take over the whole network at once. This feature is part of what makes cryptocurrencies decentralized, which means there isn’t one person in charge of them.
Cryptocurrencies like Bitcoin and Ethereum run on what’s called a proof of work (PoW) system, which means people have to solve complex equations in order to mine new coins and add new blocks to the blockchain of a digital currency.
This process is called “mining” and “block mining.” This system was made in part to fight cyberattacks where one person makes a lot of fake identities and then uses them to take over most of the network.
There are a lot of people on this network competing for the money if they can solve these math problems first. The person with the most processing power has the best chance to win.
To make things faster, people build bigger mining rigs or even networks of mining rigs. It takes more and more energy to mine new coins because the size of the network affects how much energy is used.
The cost and availability of electricity can also affect how many people are mining for cryptocurrency. If electricity costs less in one country than another, it makes sense from a business point of view to move mining to that country.
One thing to keep in mind when talking about how cryptocurrency affects the environment is that the amount of energy it uses might not be the same as the amount of carbon it emits. Harvard Business Review reports that the energy mix, or from which sources miners are getting their power, will have an impact on how much carbon dioxide is released when they mine for cryptocurrency.
In the United States, about 60% of the energy in the grid comes from fossil fuels like natural gas, coal, and petroleum, like coal. US-based mining operations may use a lot of fossil fuels for power, but that may not be the case for other mining operations in other places.
Given how much energy Bitcoin uses, though, it seems like splitting hairs to say that it doesn’t contribute to greenhouse gases in some way, given how much energy it uses.
Cryptocurrency mining can also have an effect on the environment around the power plants that are used.
Greenidge Generation plant in Dresden, New York, utilizes millions of gallons of water to keep itself cool while it’s running. Some of that water is sent back into Lake Seneca at 30-50 degrees Fahrenheit above normal, which hurts the wildlife.

Can We Reduce Crypto’s Environmental Impact?
Methane gas from fossil fuel drilling can be used to make crypto more environmentally friendly, as well as set up plants in places where wind power is plentiful, like West Texas. if the price of Bitcoin went down, it might not be financially possible to do these projects or other projects like them.
People who make new cryptocurrencies are instead looking at how to cut down on the amount of energy they use, mostly by moving to new systems of validation that don’t require proof of work.
People are becoming more interested in the proof of stake (PoS) system, which looks at how much of a certain cryptocurrency a person has agreed to keep, or not sell.
As soon as someone agrees to stake cryptocurrency, they become a “validator” on the blockchain, like a miner. They can check the validity of transactions in the same way.
Those who are chosen at random are added to the chain only if a certain number of people agree with them. As soon as a new block is made, the people who check it get coins and keep the coins they’ve staked.
This doesn’t use as much computing power as the race to solve equations that come with mining in a PoW system. Soon, Ethereum will use a different version of the PoS system to make sure that new blocks on its blockchain are correct.
There are also other ways that are being worked on, like proof of history, proof of elapsed time, proof of burn, and proof of capacity.
Some groups are also working on ways to make crypto mining and transactions more energy efficient, like the Bitcoin Mining Council and the Crypto Climate Agreement, which are both working on new ideas. To run all blockchains on renewable energy by 2025, the Crypto Climate
Accord says that it wants to do so. Some mining operations now use renewable energy, but it’s hard to figure out how much of that energy comes from renewable sources.
These steps can all cut down on the energy costs of cryptocurrency and crypto mining, but they still have to be taken into account for cryptocurrency to be long-term viable.
