Bitcoin mining is increasingly powered by greener energy, with renewables now accounting for more than half of its electricity use and the share expected to rise as new renewable projects come online.

Flexible mining demand helps stabilize grids that rely on intermittent solar and wind, encouraging further investment in renewable capacity.

A hopeful outlook frames sustainable practices and waste-heat reuse as ways for Bitcoin mining to contribute to a greener energy future and broader financial inclusion.

Some miners repurpose excess energy—such as flared natural gas or unused hydroelectric power—improving both greenness and efficiency.

Waste heat from mining could displace fossil-fuel heating, with projects like MARA’s district heating in Finland heating tens of thousands of residents and analogous efforts for homes and industrial heat.

Innovative use of mining waste heat could repurpose around 100 TWh/year for district heating, food production, and other uses, potentially lowering heating costs and emissions while supporting inclusion.

Waste heat is being repurposed for heating applications, offering a fossil-fuel alternative and extending to district, home, and industrial heating.

Common energy-use myths about Bitcoin are challenged by transparent data and ongoing hardware efficiency improvements.

Mining is framed as reducing emissions by utilizing otherwise wasted gas and methane from flaring and landfills, contributing to a claimed 7% of Bitcoin’s emissions averted through carbon-negative mining.

Bitcoin mining is described as having a carbon-negative impact by tapping into flared gas, landfill methane, and oil-field flaring, with an estimated 7% of total emissions mitigated.

Industry figure Batten portrays mining as addressing four systemic barriers to climate progress, supported by real-world data and case studies.

Mining finances renewable energy R&D, including revival of ocean thermal energy technology, and supports rural electrification in Africa via microgrids and Gridless Compute in Kenya, Malawi, and Zambia.
