Why Bitcoin isn't as bad for the environment as people think

15 AUGUST 2023

Bitcoin, the most well-known cryptocurrency worldwide, has garnered significant attention in recent years due to concerns about its purported negative environmental impact. The increasing energy consumption associated with Bitcoin mining has led to the belief that this digital currency is an ecological nightmare. However, it's important to look beyond the surface and gain a deeper understanding of Bitcoin's actual environmental impact. KPMG has also recently published a report on this topic, and its conclusions align with ours. This report can be viewed at: https://advisory.kpmg.us/articles/2023/bitcoin-role-esg-imperative.html

In this blog, we will examine and discuss claims as to why Bitcoin might not be as detrimental to the environment as commonly believed.

Decentralized Nature

A crucial aspect of Bitcoin is its decentralized nature. Unlike traditional financial systems, Bitcoin is not controlled by a central authority. This means it's not reliant on a single entity consuming vast amounts of energy, as banks do. This argument suggests that the total energy consumption of Bitcoin shouldn't be compared to that of the traditional financial system because Bitcoin doesn't require the same centralized infrastructure.

Efficient Technological Advancements

In Bitcoin's early years, the energy efficiency of mining equipment might not have been optimal. However, technological progress has led to the development of much more efficient mining hardware. Modern mining equipment can deliver much more computational power with less energy consumption. This means that despite the increase in total computational power, the energy efficiency of Bitcoin mining has improved, which can help mitigate its environmental impact.

Renewable Energy Sources

A positive trend within the Bitcoin community is the growing use of renewable energy sources for mining operations. Mining companies have become aware of environmental impact concerns and have started exploring more sustainable energy solutions. Some mining facilities now operate entirely on renewable energy, further reducing Bitcoin's ecological footprint. The KPMG researchers also suggest that Bitcoin can balance the power grid, making renewable energy plants more profitable and encouraging expansion.

Catalyst for Innovation

Criticism of Bitcoin's energy consumption has spurred discussions about potential solutions. Some experts believe that the pressure to become more energy-efficient can stimulate innovation in energy generation and storage. Consequently, technological breakthroughs resulting from these discussions could eventually lead to broader societal benefits, independent of Bitcoin itself.


While valid concerns have been raised about Bitcoin's environmental impact, it's crucial to maintain a balanced perspective on this issue. The decentralized nature, technological advancements, use of renewable energy sources, and catalyst for innovation are all factors that can mitigate Bitcoin's negative environmental impact. Rather than condemning Bitcoin outright, it might be more meaningful to explore ways the cryptocurrency industry as a whole can take positive steps towards promoting sustainability.
