As artificial intelligence continues to advance at breakneck speed, it’s running into a serious obstacle: electricity. The world’s largest tech companies—often called “hyperscalers” in Silicon Valley—foresaw the energy wall long before it hit. Training and running massive AI models now require staggering amounts of power, driving demand for new data centers, renewable energy projects, and innovative cooling solutions. This article explores how the AI revolution is reshaping global energy infrastructure, why data centers are becoming the new oil fields, and what leading firms are doing to balance progress with sustainability.
