Introduction
Bitcoin’s energy consumption has decreased by 24% since the end of July 2024, a significant milestone for the pioneer cryptocurrency. As reported by Digiconomist, the energy consumption for Bitcoin mining dropped from 152.52 TWh at the end of July to 115.21 TWh in August 2024. This is noteworthy since Bitcoin has long been criticized for its environmental impact.
Main Reasons for Energy Consumption Reduction
The reduction in energy consumption may be attributed to Bitcoin miners adopting more sustainable practices. For instance, mining projects focusing on renewable energy sources like hydroelectric power stand out. The Grand Ethiopian Renaissance Dam in Ethiopia is one such project. This major project provides local miners with access to cheaper and more environmentally friendly energy sources.
Environmental Concerns about Bitcoin
Bitcoin's energy consumption and its environmental impact are hotly debated topics. Environmentalists argue that mining activities are harmful due to high energy consumption and carbon emissions, while others dispute these claims. According to a KPMG audit report, Bitcoin mining uses only 0.55% of global energy demand and results in fewer greenhouse gas emissions compared to coal-generated electricity. These data strengthen the position of those who argue that Bitcoin is not directly harmful to the environment.
Future of Bitcoin's Energy Resources
To mitigate Bitcoin’s environmental impact, organizations like the Bitcoin Council promote sustainable mining. Alternatives with lower energy consumption, like Ethereum’s Proof of Stake (PoS) consensus mechanism, are being considered. Although it remains uncertain whether Bitcoin will adopt such measures, initiatives like the development of energy-efficient mining equipment demonstrate a commitment to environmental protection.
Conclusion
The reduction in Bitcoin’s energy consumption could usher in a new era of sustainability for the cryptocurrency. With steps towards sustainability, Bitcoin could change its perception from an environmental burden to a more eco-friendly asset. However, the more pressing issue is the cost of Bitcoin mining. If the current cost level of $83,600 persists, many miners may face bankruptcy.
