Environmental impact of bitcoin

The environmental impact of bitcoin is significant. Bitcoin mining, the process by which bitcoins are created and transactions are finalized, is energy-consuming and results in carbon emissions, as about half of the electricity used in 2025 was generated through fossil fuels. Moreover, bitcoins are mined on specialized computer hardware resulting in electronic waste. Scholars argue that bitcoin mining could support renewable energy development by utilizing surplus electricity from wind and solar. Bitcoin's environmental impact has attracted the attention of regulators, leading to incentives or restrictions in various jurisdictions.
