Bitcoin Energy Consumption

In recent years, consumers have become more conscious of energy usage and its effect on climate change, particularly regarding Bitcoin. Each Bitcoin transaction consumes approximately 1,173 kWh of electricity, equivalent to the energy used by an average American home over six weeks, with Bitcoin's total energy consumption surpassing that of Finland. This has sparked criticism from various stakeholders, including tech entrepreneurs, environmentalists, and politicians. A notable example is Elon Musk's announcement in May 2021 that Tesla would no longer accept Bitcoin payments due to environmental concerns.

While some criticize the high energy demands of Bitcoin, others argue about the extent of the problem and suggest ways to improve energy efficiency. Currently, Bitcoin mining is estimated to use 40-75% renewable energy. Critics warn that increasing this reliance could limit renewable energy for other critical areas, while proponents argue that mining could foster the growth of new renewable energy sources.

Supporters of Bitcoin also contend that traditional banking and gold mining consume more energy than Bitcoin and that Bitcoin's energy usage is more transparent. They assert that Bitcoin's energy consumption encompasses the entire process of its creation, security, and transactions, unlike conventional financial systems, which may overlook certain energy costs.

In response to these energy concerns, U.S. lawmakers held a congressional hearing to explore the future of crypto mining and its dependence on fossil fuels, including the conversion of coal plants into mining operations. Additionally, initiatives like the Crypto Climate Accord aim to tackle environmental issues, striving for net-zero greenhouse gas emissions by 2040, suggesting that Bitcoin could have a role in sustainability efforts.
