Power is the real metric (not just size)<\/h2>\n\n\n\n<p>Modern data centers are measured more by <strong>megawatts (MW)<\/strong> than square footage.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Small enterprise: 1\u20135 MW<\/li>\n\n\n\n<li>Large facility: 20\u2013100 MW<\/li>\n\n\n\n<li>Hyperscale campus: 150\u2013650+ MW<\/li>\n<\/ul>\n\n\n\n<p>A single large AI campus can consume the equivalent electricity of a small city.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2.
