根据 Ars Technica 的报道,这座发电厂的规模预计将非常庞大,足以使其成为美国温室气体排放的主要来源之一 Ars Technica。所谓“离网”数据中心,指的是不依赖现有公共电网,而是直接从专属电厂获取电力。这种模式通常是为了绕过电网接入的漫长等待期和潜在瓶颈,以最快速度满足数据中心对稳定、大量电力的迫切需求。亚马逊此举正值全球科技公司争相部署更大规模的 AI 模型之际,这些模型的训练和运行需要消耗天文数字般的电能。
亚马逊此前曾设定雄心勃勃的气候目标,包括承诺到 2040 年实现净零碳排放,并大规模投资可再生能源。然而,风能和太阳能等可再生能源的间歇性特质,使其难以独立支撑对供电稳定性要求极高的数据中心全天候运行。直接使用天然气发电,尽管会产生大量碳排放,但在当前技术条件下,是保障电力供应不间断的最可靠方案之一。这一事件反映出,在 AI 发展的竞赛中,部分企业正在将扩张速度置于短期气候影响之上。
目前,关于该电厂的具体装机容量、预计年排放量以及亚马逊是否计划采用碳捕获等技术来抵消排放等细节,原文未提供。但可以确定的是,这一项目将重新点燃关于科技公司气候责任与 AI 发展代价的辩论。如何在推动技术创新与履行环境承诺之间找到平衡,正成为整个行业面临的严峻考验。

Amazon’s artificial intelligence ambitions will soon be partly fueled by a natural gas-burning power plant in Texas that “could become the largest single source of climate pollution in the United States,” The New York Times reported.
These gas-burning plants are increasingly lumped into data center projects. They produce harmful pollutants, which can accelerate climate change impacts and harm public health—contributing to conditions like asthma, heart disease, lung cancer, and strokes. Some communities are demanding more stringent environmental reviews, but the Trump administration favors fast-tracking that can include skipping the permitting process entirely.
Since Elon Musk’s xAI controversially began relying on gas turbines last spring to power its biggest AI data center, Colossus, there has been public backlash to off-the-grid data centers like the one Amazon is building.
