生成AIの普及などにより社会を支える基盤としてデータセンター（以下、「DC」）を含むデジタルインフラの重要性が急速に高まっています。その一方で、デジタルインフラを取り巻く課題も顕在化しています。
特にDCの電力需要※は、エネルギー消費の改善幅が小さい場合、2030年に年間240億kWh、2050年では5,000億kWh（日本全体の住宅を除く非住宅建築物の床面積約26億㎡が消費するエネルギーの約1.2倍※※）にまで急増して、国全体の電力需給に大きな影響を与えることが懸念されています。また、DCの約85％が東京・大阪圏に集中しているため、南海トラフ地震のような大規模災害時のリスクが懸念されています。さらには、既存DCの多くが老朽化しており、エネルギー性能や運用効率の改善余地があるにもかかわらず、抜本的な再整備が進んでいません。
