Cryptocurrency, especially Bitcoin, has revolutionized finance, but its environmental footprint has sparked heated debates. As blockchain technology powers digital currencies, its energy consumption raises concerns about sustainability. This article dives into the environmental impact of crypto, why it matters, and what’s being done to address it. Whether you’re a crypto enthusiast or a curious beginner, here’s everything you need to know. Why Does Crypto Use So Much Energy? Cryptocurrencies like Bitcoin rely on blockchain, a decentralized ledger that records transactions securely. To maintain this ledger, computers perform complex calculations in a process called mining.

The Environmental Concerns The energy demands of crypto mining translate into real environmental impacts. Here are the key issues: For example, a single Bitcoin transaction can consume as much energy as an average U.S. household uses in a month—roughly 700 kWh. This statistic has fueled criticism from environmentalists…
