A study by Alex de Vries-Gao reveals that global AI power demand could reach 23GW and consume 312.5 to 764.6 billion liters of water in 2025, surpassing the energy usage of Bitcoin mining in 2024. These estimates are considered conservative as big tech companies do not disclose the full extent of their AI operations' consumption in sustainability reports. U.S. lawmakers, including Senator Elizabeth Warren and Senator Bernie Sanders, are raising concerns about the environmental impact of AI data centers, with Sanders proposing a moratorium on their construction. Experts suggest that the environmental impact of AI extends beyond operations to the entire supply chain, potentially increasing the environmental footprint of AI technology significantly.

NSA using Claude Mythos for 'offensive cyber operations,' report claims — says 'half-a-dozen' Anthropic engineers embedded inside the agency

The National Security Agency (NSA) is reportedly utilizing Anthropic's cybersecurity-focused Mythos model for "offensive cyber operations," with several Anthropic engineers embedded within the agency. This move aims to gain an advantage over adversaries who may also be using similar AI models. Despite Anthropic being banned from providing services to the Department of Defense (DOD), the engineers are assisting in customizing Mythos for specialized cyber-attacks. The situation stems from a dispute between Anthropic and the DOD over the use of AI for various purposes, leading to Anthropic being labeled a supply chain risk. The ongoing legal battle between Anthropic and the DOD adds complexity to the situation, raising questions about the future of their relationship.

Seattle to pass one-year AI data center moratorium next week — will use window to study community impact of AI buildouts

Seattle is set to implement a one-year moratorium on AI data center construction to assess the impact on the community. The decision follows public support and concerns about issues like increased electricity bills and environmental impacts. The city plans to use this period to study the effects of data centers on the surrounding areas and establish regulations for their development. Residents have backed the temporary ban, highlighting worries about pollution, noise, and land use. This move contrasts with other states where politicians have faced opposition for supporting data center projects.
