Total previous green investments are $8-10 trillion, while fossil fuel consumption's not gone down (fossil fuel investment is falling, though.) That Stanford study undercounts and presumes a massive increase in storage.
If really dig in, our current renewable layout focuses on the low hanging fruit, but storing solar energy till the night time or a different part of the year is infeasible (look into "duck curves") and currently done by burning natural gas. Current storage production is up a full magnitude, but we need multiple further magnitudes more to do a full transition. The increase in transmission lines alone is more than all known copper (mined and unmined).
Green energy already sees nearly $2 trillion in yearly capex: https://www.iea.org/reports/world-energy-investment-2023/ove...
