ドイツで初めて風力と太陽光が化石燃料を上回る
Wind and solar overtake fossil fuels in Germany for the first time (intellinews.com)
要約
2025年、ドイツでは初めて風力・太陽光発電量が化石燃料を上回り、225 TWh対217 TWhとなりました。これはEU全体でも見られた傾向であり、ドイツの「Energiewende」戦略による再生可能エネルギーへの移行と、原子力・石炭からの段階的撤退を反映しています。同国は2045年までのカーボンニュートラル目標達成に向け、再生可能エネルギーの導入を加速させています。

Search Wind and solar overtake fossil fuels in Germany for the first time ever Carbon Brief's analysis of Energy Institute data shows renewables generated 225 TWh in 2025 against 217 TWh from fossil fuels — a milestone Germany shares with the EU as a whole, even as it leans harder on renewables than neighbours to compensate for its nuclear phaseout. / bne IntelliNews By bne IntelliNews August 1, 2026
ドイツでは、エネルギー研究所の統計レビュー・オブ・ワールド・エナジーのデータ分析によると、2025年に初めて風力・太陽光発電が化石燃料を上回りました。風力と太陽光を合わせた発電量は225テラワット時(TWh)で総発電量の44%を占めたのに対し、化石燃料は217 TWh(43%)でした。これは、2025年に風力・太陽光発電が初めて化石燃料発電を上回ったEU全体と共有する節目です。

この転換は、ドイツの「Energiewende」戦略の下で、石炭と原子力の両方から移行する同国における太陽光および陸上風力発電の20年間にわたる急速な成長を反映しています。ドイツは2030年までに115ギガワット(GW)の陸上風力発電容量の設置を目指しており、2025年だけで過去最高の20.8 GWの新規容量が承認されました。公式目標では、2045年までに経済全体でネットゼロ排出、2030年までに電力消費の80%を再生可能エネルギーで賄うこと、そして2035年までに「ほぼ気候中立」な電力システムを達成することが求められています。
ドイツは、その原子力発電の段階的廃止(Energiewendeの主要な柱であり、最近の反発にもかかわらず政治的に確定している)のために、フランスや英国のような近隣諸国よりも再生可能エネルギーにさらに依存する必要があります。中道右派のフリードリヒ・メルツ首相は今年初め、原子力発電の段階的廃止を「戦略的誤り」と評しましたが、彼の政権は従来の原子力発電への回帰を排除しています。
石炭は当面のより大きな課題であり続けています。ドイツは依然として他のほとんどの欧州諸国よりも石炭に大きく依存しており、公式な廃止期限は「遅くとも」2038年ですが、専門家は、最近のエネルギー危機中に移行を遅らせる圧力があったにもかかわらず、同国がその日付より数年早く電力供給から石炭を排除する軌道に乗っていると考えています。
しかし、再生可能エネルギーは今、異なる種類の反対に直面しています。それは、極右政党「ドイツのための選択肢(AfD)」からの高まる抵抗です。同時に、現政権は独自の新しいガス火力発電所の建設も進めています。これらは橋渡し技術として法制化され、2045年までにグリーン水素で稼働するように転換され、気候中立目標との整合性を保つ予定です。AfD以外の声で石炭の段階的廃止を完全に中止しようと呼びかける声は非常に少ないですが、政府は8月にタイムラインの見直しを発表する予定であり、これがベルリンがどこまで断固として方針を維持するかの次の試金石となるでしょう。
