A battle over energy cost is brewing in the crypto space, as a new report from technical analyst Bullrunners pits Bitcoin’s (BTC) energy-hungry Proof of Work (PoW) system against XRP’s comparatively lightweight network. The new analysis has thrown fresh fuel on one of crypto’s oldest rivals, sparking intense debate among crypto community members as they attempt to defend their preferred blockchain network. 

A new report from Bullrunners has reignited the long-standing debate between Bitcoin and XRP, this time over a striking difference in energy consumption between the two networks. According to the report, posted on X this Tuesday, XRP consumed just $73,000 worth of electricity to run its entire network over the course of a full year. Bitcoin, by contrast, used over $10 billion in electricity during the same period. 

Breaking that down further, Bullrunners shared an image which showed that a single Bitcoin transaction carries an energy cost equivalent to powering an average American household for 38 to 49 days, consuming between 1,100 and 1,400 kilowatt-hours (kWh). Meanwhile, a single XRP transaction uses approximately 0.0079 kilowatt-hours (kWh), roughly the amount of energy needed to power a light bulb for a few seconds. 

Based on this sheer difference in energy consumption, Bullrunners concluded that the XRP network uses up to 99.999% less energy than Bitcoin. 

Notably, a major reason for this extraordinary energy gap is how each blockchain network validates transactions. Bitcoin’s PoW system requires miners worldwide to continuously compete by solving complex mathematical puzzles using energy-intensive hardware that consumes vast amounts of electricity. 

On the other hand, XRP relies on a special XRP Ledger (XRPL) Protocol Consensus algorithm. Instead of mining, a group of trusted nodes communicates and votes across several rounds until they reach an agreement on which transactions are valid. With no competition and no energy-intensive mining hardware, the XRP network can settle transactions at a fraction of Bitcoin’s energy cost. 

Bullrunners’ energy report quickly drew sharp reactions from members of the crypto community, with supporters of each blockchain network offering different interpretations of what Bitcoin and XRP’s energy numbers really mean. 

One supporter argued that Bitcoin’s energy consumption is not wasteful, but essential to its security. He described the network’s PoW mechanism as a process that converts real-world energy into a form of unforgeable digital scarcity. He went on to challenge XRP’s decentralization, pointing out that Ripple holds billions of the token and could influence supply without the constraints of a hard cap. 

XRP supporters fired back with their own case, advocating that the XRP Ledger’s energy efficiency places it ahead of not just Bitcoin but also Ethereum, even after it transitioned to a Proof of Stake (PoS) consensus in 2022. They maintained that XRP is much more energy-efficient than Ethereum on both a per-transaction and network-wide basis.
