Overview of Energy Use
What Does Energy Use Mean?
Energy use refers to the amount of power consumed by processes, devices, systems, or operations over a specific period. Bitcoin mining and manufacturing sectors dramatically differ in their energy consumption patterns due to the nature of their operations. While Bitcoin mining primarily involves computational power, manufacturing involves various processes such as production, assembly, and machinery operations.
For specialized reading, you can explore books like “Sustainable Energy – Without the Hot Air” by David MacKay for more insights into energy use patterns across different sectors.
Bitcoin Mining Energy Use
Bitcoin mining is an energy-intensive process involving complex computations to validate transactions and add them to the blockchain. Each Bitcoin transaction relies on solving cryptographic puzzles, which consumes a lot of computational power. The machines used, mainly ASIC (Application-Specific Integrated Circuit) miners, are designed to solve these puzzles quickly but require significant amounts of electricity and cooling systems to maintain optimal performance.
Data from the Cambridge Centre for Alternative Finance shows that Bitcoin’s annual energy consumption is comparable to that of some small countries, estimated at around 110 TWh (Terawatt Hours) in 2023. This is primarily because miners set up large facilities equipped with thousands of these ASIC devices working round the clock.
Industry-specific Comparisons
Energy Use in Different Manufacturing Sectors
Manufacturing industries vary widely in their energy needs depending on the type of goods produced. For instance, the steel industry consumes a tremendous amount of energy during the smelting and refining processes, while the textile industry primarily uses energy for machinery and chemical treatments. According to US Energy Information Administration (EIA) data, the industrial sector accounted for about 33% of total U.S. energy consumption in 2022.
Books like “Manufacturing Processes for Design Professionals” by Rob Thompson provide a detailed understanding of energy uses across different manufacturing processes. They dive deep into how different stages, from raw material extraction to final product assembly, influence overall energy consumption.
Energy Efficiency and Operational Differences
Operational scale is a critical factor in energy consumption. Bitcoin mining operations are highly centralized, with most of the hashing power controlled by large mining pools. This centralization can drive energy use upwards because miners compete to solve the same puzzle, leading to redundant energy use.
In contrast, manufacturing processes can vary from highly centralized to widely dispersed. Manufacturing plants often adopt energy efficiency measures, such as using modern machinery and optimizing processes. The automotive industry, for example, has made significant strides in reducing energy use per vehicle manufactured by adopting lean manufacturing techniques and advanced robotics.
In “The Energy Efficient Factory of the Future,” authors Patel and Thakur detail how various efficiency measures can drastically reduce energy consumption in manufacturing settings.
Arguments For and Against Energy Use in Both Sectors
Bitcoin Mining Energy Use: Pros and Cons
Proponents of Bitcoin argue that its energy use is justified by the security and decentralization it brings to the financial system. Bitcoin mining ensures the integrity of the ledger, providing a trustless system free from central control.
However, critics highlight the environmental impact and question whether such high energy consumption is justified. They suggest alternatives like proof-of-stake (PoS), which consumes significantly less energy. For more on this, check out Inside Story: The Debate Over Bitcoin’s Environmental Impact.
Manufacturing Energy Use: Pros and Cons
On the other hand, manufacturing sectors argue their energy use is necessary for societal development, producing goods essential for everyday life. However, they face criticism for relying on non-renewable energy sources and contributing to pollution.
Books like “Green Manufacturing: Fundamentals and Applications” by David A. Dornfeld explore methods to mitigate the environmental impacts of manufacturing energy use.
To sum up, understanding the energy use dynamics in Bitcoin mining and manufacturing requires a deep dive into industry specifics. These sectors display significant differences in how they consume and manage energy, reflecting their unique operational needs and priorities.

Carbon Emissions
Bitcoin mining is notorious for its high carbon footprint. Each Bitcoin transaction may generate several hundreds of kilograms of CO2, close to that of hundreds of thousands of Visa transactions or tens of thousands of hours of YouTube watching. This is mainly due to the energy-intensive nature of the proof-of-work (PoW) algorithm. According to the Cambridge Centre for Alternative Finance, Bitcoin mining consumed around 110 Terawatt-hours of electricity in 2023. This consumption is higher than some small countries’ total energy use. Coinciding with this high energy consumption, Bitcoin mining also emits a significant amount of CO2, contributing more to global warming.
In contrast, the industrial sector, while a significant CO2 contributor, varies in emission intensity based on industry type and geographic location. Manufacturing, especially in industries like steel or cement, produces substantial greenhouse gases. According to the International Energy Agency (IEA), the industrial sector accounts for about 24% of global CO2 emissions. However, industries also have established practices for limiting emissions, including the adoption of cleaner technologies and regulations mandating emission reductions.
Books and Further Reading
For those interested in a deeper dive into carbon emissions, the books “Energy and Civilization: A History” by Vaclav Smil and “Sustainable Energy – without the hot air” by David JC MacKay provide comprehensive overviews of energy use and emissions in human history.
Resource Depletion and Waste Generation
Bitcoin mining demands significant amounts of electronics, particularly ASIC miners (Application-Specific Integrated Circuits).
