How Much Energy Does AI Use? The People Who Know Aren’t Saying
The article discusses the opaque nature of energy consumption data related to AI, particularly large language models like ChatGPT. OpenAI CEO Sam Altman claimed that an average ChatGPT query uses about 0.34 watt-hours of energy, roughly equivalent to a high-efficiency lightbulb running for a couple of minutes. However, experts criticize this figure for lacking transparency and context, such as whether it includes energy used for training models, server cooling, or image generation. OpenAI has not provided detailed disclosures explaining how this number was calculated, leading to skepticism among researchers like Sasha Luccioni from Hugging Face, who emphasizes the need for more comprehensive environmental transparency in AI. The article highlights a broader issue: most AI models in use today do not disclose their environmental impact, with 84% of large language model traffic in May 2025 coming from models with zero environmental disclosure. This lack of transparency hampers efforts to accurately assess AI’s carbon footprint, especially as AI usage grows rapidly. Misleading

The article from CleanTechnica addresses renewed criticism of electric vehicles (EVs), sparked by comments from Akio Toyoda, president of Toyota, who argued that in Japan—where electricity generation relies heavily on thermal power plants—producing EVs could increase carbon emissions compared to hybrids. This statement was seized upon by anti-EV groups to claim that EVs are worse polluters than hybrids or gasoline cars. However, the article highlights that such claims often stem from misinformation or ideological bias against EVs and fail to consider the full lifecycle emissions of vehicles. Scientific studies, including one published by IOP Science, acknowledge that EV manufacturing produces higher initial carbon emissions due to battery production, creating a "carbon debt." Yet, over their operational lifetime, EVs offset this debt by producing significantly lower emissions during use, especially as electricity grids become cleaner. The breakeven point for EVs to become cleaner than hybrids is typically between 20,000 and 30,000 miles, and even shorter when

The article discusses a movement in Puerto Rico advocating for reunification with Spain, reflecting a desire among some residents to escape the island’s current status as a U.S. territory. Puerto Rico was a Spanish colony for over four centuries until the Spanish-American War in 1898, after which it became a U.S. possession. Although Puerto Ricans are U.S. citizens, they lack voting representation in Congress and cannot vote in presidential elections, while many do not pay federal taxes. This political limbo, combined with economic challenges such as high costs for imported goods and electricity (due in part to shipping restrictions favoring U.S.-registered vessels), fuels dissatisfaction. The movement, led by José Lara and called Adelante Reunificacionistas, seeks to make Puerto Rico the eighteenth autonomous community of Spain, citing shared language and culture as key reasons. Supporters of reunification argue that Spanish governance could help Puerto Rico overcome economic and cultural stagnation experienced under U.S. rule. The article highlights historical grievances
