-- Meta Platforms（META）は月曜日、Overview EnergyおよびNoon Energyと提携し、最大1ギガワットの宇宙太陽光発電と長時間エネルギー貯蔵システムを提供することで、同社の人工知能インフラとデータセンターに電力を供給すると発表した。 Overview Energyの太陽光発電衛星は、宇宙からエネルギーを収集し、地上の太陽光発電施設に送電することで、「既存の太陽光発電所の容量を増強し、24時間体制の発電を可能にする」と同社は述べている。 既存の太陽光発電および送電網インフラを活用することで、この技術による電力供給は、従来の新規建設による電力供給に比べて、より迅速に大規模に展開できると見込まれている。 METAは、2028年に予定されている軌道上実証実験が成功すれば、2030年にも商用サービスを開始できる可能性があるとしている。 一方、Noon Energyのバッテリー技術は、従来のリチウムイオン電池ではなく、炭素系蓄電池を使用し、最大1ギガワット（100ギガワット時）の超長時間エネルギー貯蔵容量を提供する。 両社は、最初の25メガワット（2.5ギガワット時）の実証パイロットプロジェクトを2028年までに完了させる予定である。 Meta社は、データセンターの運用を支えるために、これまでに30ギガワット以上のクリーンエネルギーおよび再生可能エネルギーを契約したと発表した。同社は、Sage Geosystems社およびXGS Energy社と提携して次世代地熱エネルギーの開発を進めており、Vista（VST）、TerraPower、Oklo（OKLO）、Constellation Energy（CEG）から7.7ギガワットの原子力エネルギーを購入している。

Case-Shiller reports percentage gains both from the previous month and a year earlier.Higher home prices are inflationary and are usually negative for bonds. The possible outcome for housing-related stocks is mixed, as higher prices suggest strong demand, but prices that are accelerating too fast can also deter potential buyers.
