Исторический контекст и эволюция ветрогенераторов

Ветроэнергетика имеет древние корни, начиная с простых ветряных мельниц, используемых для помола зерна и перекачки воды. Однако современная эра ветрогенераторов началась в конце XIX века с изобретения электрических генераторов. Первые коммерческие ветряные турбины, такие как те, что разработаны в Дании в 1890-х годах, были небольшими и неэффективными, с мощностью всего несколько киловатт. К середине XX века технология продвинулась, но оставалась нишевой из-за высокой стоимости и ограниченной надежности.

Переломный момент наступил в 1970-х годах с нефтяным кризисом, который стимулировал инвестиции в альтернативную энергетику. Правительства и компании начали активно развивать ветроэнергетику, приводя к созданию более крупных и эффективных турбин. В 1980-х и 1990-х годах появились первые мегаваттные турбины, а к 2000-м годам ветроэнергетика стала конкурентоспособной с традиционными источниками энергии благодаря снижению затрат и улучшению технологий.

Сегодня ветрогенераторы достигли впечатляющих масштабов: офшорные турбины могут иметь мощность свыше 15 МВт и лопасти длиной более 100 метров.
