Professor Coin Explores Bitcoin's Role in Sustainable Crypto Future

Bitcoin's energy consumption remains high, with recent estimates at 138 TWh annually, raising environmental concerns beyond just carbon emissions to include water, land, and e-waste impacts. While Bitcoin continues to use proof-of-work, which is energy-intensive, alternatives like Ethereum's proof-of-stake demonstrate that blockchain networks can be secure and more sustainable. Policy pressures are increasing, and the future of crypto's environmental impact depends on technological, regulatory, and community choices.
