Investment in solar energy will finally exceed that in oil this year.

The International Energy Agency (IEA) predicted on Thursday that for the first time ever, this year’s global investment in solar power will surpass that in oil output.

By 2023, the International Energy Agency estimates that $380 billion will be invested in solar energy, vs $370 billion for oil exploration and extraction.

Dave Jones, head of data insights at energy think tank Ember, claimed that this “establishes solar as a true energy superpower.”
