Cryptocurrency's impact on the environment
Cryptocurrency has sparked debates not just for its financial potential, but also for its environmental impact. Energy-intensive processes like Bitcoin mining require vast amounts of electricity, often relying on non-renewable sources.
As the crypto industry grows, concerns over its carbon footprint and resource consumption increase. However, emerging technologies, like proof-of-stake, and a shift toward greener energy solutions are offering hope for a more sustainable future in the crypto space.
Cryptocurrency and the Environment
The most popular cryptocurrencies are Bitcoin and Etherum. So-called altcoins such as Cardano and Render are continuing to gain traction with Render’s price reaching a new high according to Binance data.

Many cryptocurrencies however, depend on energy-hungry processes like mining, which require substantial computational power to verify transactions and maintain network security. This process consumes large amounts of electricity, often generated from fossil fuels, leading to significant environmental impact. The environmental footprint has sparked growing concern. As the crypto industry expands, its reliance on energy resources has raised important questions about sustainability and the future of digital currencies in a world increasingly focused on reducing carbon emissions.
Electricity Usage
The electricity required to power this massive infrastructure is tremendous. By some estimates, it equals 121 terawatt-hours of energy per year. Some have said that the carbon footprint is bigger than that of countries like Argentina.
Other forms of payment consume far less. For example, credit card processing does billions of transactions a year and uses much less energy.
Additionally, the costs climb rapidly. Cryptocurrencies require more electricity as their popularity increases. This is because the math problems they solve get harder as the price of coins increases. More computer time is required to generate each coin and thus more energy is required.
In the beginning, cryptocurrency could be mined by hobbyists with their PCs at home. As it’s become a big business, the process has industrialized. Some miners are publicly traded companies. The most popular location is rural China, where land and electricity are very inexpensive. The energy comes from inefficient and outdated coal-based power plants.
Climate Impact
Climate change is one of the biggest concerns of our time. We’re already seeing the effects with higher average temperatures and extreme weather conditions. Notable leaders and environmentalists have criticized cryptocurrencies for their impact on the environment.
With the economies of developing countries booming, human society is already struggling to slow down the growth of carbon use. What is it supposed to do if the future of the financial system is so thirsty for energy?
Some might argue that it’s difficult to measure the global impact. After all, one of the major advantages of crypto is that it’s all anonymous. It is a challenge to calculate worldwide usage trends.
Different mining rigs have different consumptions of electricity. Those with newer chips will be more powerful and more energy-efficient. Eventually, old rigs won’t be cost-competitive and miners will scrap them to invest in new ones.
Miners have a tremendous variety of sources of power. While a lot might come from inefficient coal power plants, some might have solar panels on their facility.
A researcher did a calculation that even if all the rigs are highly-efficient, cryptocurrency consumes as much as the country of Slovenia.
There’s no way to know whether down the line a more environmentally friendly cryptocurrency will emerge. And even if the costs are great, what if the benefits are massive as well? Real use cases of crypto are still emerging. But what if international transfer fees are slashed? That could save billions for migrant workers. If cryptocurrencies replace ones based on fiat (like the dollar or the euro), world economies might be more stable and there could be lower interest rates. It’s hard to know.
Cryptocurrency is now mainstream and is a major trend. It has a big negative impact on the environment. However, things might change and the benefits might be massive.
