The impact of energy choices and environmental issues in cryptocurrency mining in 2019
The energy consumption of mining has garnered increasing interest in 2019, as the race for brute power has a significant environmental impact. The mining sector is often criticized for its high electricity demand, pushing actors to seek more economical and sustainable energy sources.
Historically, China dominated the market with its mining farms set up in regions with cheap hydroelectric power. However, in 2019, geopolitical phenomena and local restrictions began to hinder this hegemony. This evolution allowed the emergence of mining farms in countries like the United States, Canada, and Kazakhstan, where renewable energy production has become a major argument.
One of the major responses in 2019 was the creation of initiatives promoting energy transparency and sustainability. The Bitcoin Mining Council, for instance, brings together several significant miners engaged in a carbon footprint reduction effort. The goal is to promote the use of renewable sources (hydroelectric, wind, solar) while improving operational processes to limit waste.
The debate over energy consumption has also prompted some developers to explore alternative validation algorithms, such as the gradual transition to Proof of Stake observed on Ethereum. This evolution fundamentally alters how cryptocurrencies are secured, thus reducing dependence on energy-intensive mining.
In practice, for miners, these changes translate into a constant reassessment of their variable costs. The integration of renewable energies offers a dual advantage: reducing the carbon footprint and lowering the energy bill. However, not all mining pools have such advantages, which intensifies competition and disparities.
List of energy strategies adopted in 2019:
- Geographical diversification of mining farms towards renewable energy areas
- Participation in coalitions like the Bitcoin Mining Council to promote sustainability

The growing role of mining pools and their influence on decentralization
The rise of mining pools in 2019 changed the very structure of cryptocurrency mining. These groups of miners combine their resources to increase the chances of successfully validating a block and receiving the associated rewards. This dynamic, while promoting efficiency, raises several crucial questions for the future of networks.
Pools experienced diversification in both size and specialization depending on the cryptocurrencies. For instance, on the Bitcoin network, pools like F2Pool, Slush Pool, or Antpool, mostly linked to Chinese operators and other regions, controlled a significant share of the global hashrate in 2019.
The impact of this concentration has led to debates about the centralization of mining, a problem antithetical to the decentralized spirit of blockchains. On one hand, participation in a pool helps stabilize miners’ revenues and reduce volatility; on the other hand, it grants significant power to operators, who may manipulate the network or favor certain blocks.
Moreover, the technical operation of pools has evolved to incorporate more secure and transparent solutions, enhancing miners’ trust. Real-time monitoring tools, as well as specific protocols to limit centralization, have been implemented.
This phenomenon is not exclusive to Bitcoin. The mining of other cryptocurrencies like Ethereum also relies on well-established pools, suited for GPU use. The growing popularity of altcoins has thus contributed to a diversification of pools and intensified competition.
List of the effects of mining pools in 2019:
