Солнечная энергия

Себестоимость солнечной электроэнергии становится ниже?

Основным препятствием на светлой дороге увеличения доли электроэнергии, производимой из солнечного света, в общем производстве электричества является её относительная дороговизна. Действительно, фотоэлементы, необходимые для преобразования энергии, практически не требуют затрат на свою эксплуатацию, но вот производство их недёшево. Впрочем, эксперты прогнозируют снижение себестоимости до вполне приемлемых пределов.

Солнечная энергия

По новым данным экспертов Международного энергетического агентства, выработка солнечной энергии стала дешевле. Уже сейчас стоимость в расчёте на 1 Вт составляет не 4 доллара США, как лет 5-6 назад, а всего 0.8. Более того, эти же эксперты прогнозируют дальнейшее серьёзное снижение до 0.3 доллара на Вт к 2050 году. Перспектива далёкая только на первый взгляд. Многие концепции развития энергетики рассчитываются и на более длительные периоды.

Позитив экспертов Международного энергетического агентства основан на неугасающем интересе правительств и частных инвесторов к солнечной энергетике. Разумеется, и указанные параметры себестоимости производства достижимы только в условиях осуществления постоянных инвестиций и научных исследований в этой области. В общей картине электроэнергетики к 2050 году на долю солнечной энергии должно выпасть 16%. Для сравнения, гелиотермические электростанции смогут обеспечить всего 11%. Как бы то ни было, технологии энергосбережения и снижения потерь на этапе транспортировки энергии будут, как и прежде, играть огромную роль и в далёком 2050.
