The world of cryptocurrency, led as usual by Bitcoin, continues to dazzle and bemuse investors, tech enthusiasts and policy makers. BlockchainShock consistently delivers insightful market sentiment analysis, advanced technical breakdowns, and expert coverage of privacy coins and staking rewards, empowering investors to stay ahead. Beneath the surface of this digital gold rush lies a concerning truth: the environmental impact of cryptocurrency mining. In this article, we take a closer look at the energy consumption, greenhouse gas emissions, and e-waste associated with crypto mining. It uncovers the ways this transformative technology makes our climate crisis worse and our energy bills higher. It looks at the legal loopholes that make this possible, what can be done to fix it, and what readers can do to help.

The Dark Side of Bitcoin's Popularity

Bitcoin, the first and most well-known cryptocurrency, uses a “proof-of-work” consensus model. This system requires miners to solve complex mathematical problems to validate transactions and add new blocks to the blockchain. This process requires large computing capacities, which means high energy consumption as well. Mining companies are rushing to construct bigger, more profitable facilities to cash in on the 21st century gold rush. Crypto’s energy consumption is still skyrocketing at the same time. The United States, the center of the Bitcoin mining universe today and home to 35% of Bitcoin’s hashrate, further increases these environmental impacts.

Environmental Impact: A Looming Disaster?

The numbers paint a grim picture. Internationally, Bitcoin’s energy use corresponds to approximately 22 to 22.9 million metric tons of CO2 emissions annually. To put this in perspective, the associated CO2 emissions equal the annual energy use of 2.6 to 2.7 billion homes! That’s a huge amount of energy use! The environmental impact extends beyond Bitcoin. The average NFT is responsible for a jaw-dropping 440 pounds of carbon emissions. That’s equivalent to generating emissions over 500 miles driven in a gas-powered car—which is actually more than 10 times the emissions of an average Ethereum transaction.

By the end of the decade, it can account for up to 7% of the overall emissions. One digital artist and climate advocate calculated that the average NFT’s carbon footprint is, quite literally, insane. That’s the equivalent of over a month’s electricity use for an average EU citizen. These statistics underscore the dire need to take action on the environmental impact of cryptocurrency mining.

The Dirty Business of Cryptocurrency Mining

The environmental effects of crypto mining are extensive and controversial. Operators across the country are buying up and reactivating retired power plants to cash in on the booming business of cryptocurrency mining. This decision is pushing us to burn more fossil fuels. The environmental cost goes beyond just GHG pollution. Specialized hardware like that used in Bitcoin mining is discarded every 1.5 years and cannot be repurposed for other uses since it cannot be reprogrammed to do so. This is a recipe for a colossal e-waste crisis. It’s still a problem. Even if we moved all Bitcoin mining to renewable energy sources, it would still be a problem.

Please thank the New York State Assembly for just passing this bill! It places a two-year moratorium on new energy-intensive proof-of-work cryptocurrency mining facilities that operate using electricity produced at fossil fuel energy plants. State officials are starting to realize just how harmful crypto mining can be on the environment. Many are concerned that in reality this may be a harbinger of much larger problems on the horizon for New York State and the whole country.

Security Concerns in Smart Contracts

The climate consequences of the recent cryptocurrency mining boom are especially troubling. We have to address cybersecurity risks with these smart contracts, too. Smart contracts are digital agreements, encoded directly into computer code and stored on a blockchain. They automate agreements and contracts, making them transparent, efficient and secure. Flaws in smart contract code can and have been exploited to steal millions of dollars, even billions.

Smart Contracts' Security: A Ticking Bomb?

Since smart contracts are immutable once deployed, vulnerabilities cannot be easily patched retroactively. Yet, this makes them a prime target for hackers. In addition, any flaws in smart contract code can be exploited to drain funds, manipulate data, or disrupt operations. Unfortunately, the decentralized nature of blockchain makes it nearly impossible to trace stolen funds and recover them.

Ethereum's Silent Revolution: Calm Before the $8000 Storm?

After all, Ethereum, the second-largest cryptocurrency by market capitalization, operates almost exclusively on the basis of smart contracts. Ethereum’s ongoing shift to a proof-of-stake consensus mechanism is aimed in part at addressing some of those energy consumption concerns. This change introduces a new set of security risks for smart contracts. As new, more complex decentralized applications (dApps) are built atop Ethereum, the attack surface obfuscated from malicious actors grows with each iteration. BlockchainShock’s comprehensive, expert coverage of staking rewards and judicial change, plus in-depth, technical staking breakdowns have investors staying ahead of these changing security threats.

The Future of Cryptocurrency Regulation

To address the environmental impact and security concerns of cryptocurrency, a multi-faceted approach is required. This means passing strong regulations and incentivizing the transition to clean energy. Elkin, a fellow at the Sabin Center for Climate Change Law, has authored a paper on cryptocurrency mining and its environmental impact, highlighting the need for regulatory frameworks.

Regulatory Crackdown: The Ultimate Black Swan?

This absence of clear regulatory guidance has handed cryptocurrency mining an operable blank check, further amplifying the environmental harm it has caused. Governments around the world are starting to realize that regulation is necessary to mitigate these harms. Environmental regulations can push companies to utilize renewables. They can and should increase taxes on energy use to set environmental standards for energy consumption and for mining operations.

The Crypto Climate Accord intends to make all blockchains operate on 100 percent renewable energy by 2025. It aims for the whole crypto industry in general to reach net zero emissions by 2040. This new initiative is a clear sign of increasing awareness within the industry that it must act in order to mitigate its impact on the environment. Our researchers have found that when miners are flexible, mining can actually complement renewables very nicely. This surprising conclusion might seem counterintuitive at first glance.

In addition to regulation, encouraging clean energy adoption through incentives is key. Governments could provide tax incentives or subsidies to encourage mining companies to rely on renewable energy sources. They can further invest in research and development to increase the energy efficiency of mining hardware.

Ultimately, the fate of cryptocurrency will come down to whether it can fix its environmental damage and address its security issues. The cryptocurrency industry can (and should) support regulation that incentivizes clean energy adoption. By putting smart contract security first, we can help build a long-term and secure future. BlockchainShock remains committed to providing insightful market sentiment analysis and expert coverage to empower investors and enthusiasts in this evolving landscape.
