The ever-increasing popularity of cryptocurrencies has once again come under fire, this time due to its environmental costs. Novel Greenpeace report takes a critical look at the energy consumption of Bitcoin mining, pointing the finger directly at the Wall Street financiers who support the industry.
Wall Street’s sullied little secret?
The report argues that conventional financial institutions are deeply linked to the environmental impact of Bitcoin mining. While Bitcoin itself operates on a decentralized network, the massive mining facilities required to secure the currency are funded and backed by Wall Street giants.
Despite the myth of Bitcoin’s independence from conventional finance, the industry relies heavily on banks, asset managers and venture capitalists for the capital it needs to operate, according to the report.

Greenpeace identifies several major financial institutions, including BlackRock and Vanguard, as the main institutions financing Bitcoin mining companies in 2022. The report calculates that these institutions, along with others, are indirectly responsible for over 1.7 million metric tons of CO2 emissions – equivalent to emissions the annual electricity consumption of hundreds of thousands of homes.

Is proof of work a problem?
The heart of environmental concern lies in Bitcoin’s underlying technology – Proof of work (PoW). This system relies on a expansive network of computers that solve convoluted mathematical puzzles to validate transactions and secure the network. The more computing power allocated to the network, the safer it becomes, but this also translates into a huge demand for electricity.
Greenpeace argues that the PoW system is simply unsustainable in the face of climate change. They propose moving towards alternative consensus mechanisms, such as proof of stake, which utilize much less energy.

However, some industry experts warn against hasty change. Proof-of-Work has proven to be extremely sheltered for Bitcoin for years. Switching to a different system may introduce recent security vulnerabilities that we haven’t even considered yet.
Finding a Sustainable Future: Can Cryptocurrencies Go Green?
The debate over Bitcoin’s environmental impact is far from settled. While Greenpeace expresses legitimate concerns about the role of Wall Street and the inherent energy inefficiency of PoW, there are other factors to consider.
Some bitcoin mining companies are increasingly turning to renewable energy sources such as solar and geothermal energy. Additionally, research is ongoing on ways to optimize the PoW system itself to reduce its energy footprint.
Bitcoin’s future depends on several key actions. Miners and financial institutions need to be more limpid about energy consumption. It is significant to discover recent extraction methods and regulate energy sources. The main challenge is to ensure Bitcoin’s growth without harming the environment.
