Once you factor in environmental cost, renewables have been cheaper for a long time.
Everything dropping in price has helped a lot too, of course. Like the article says, solar panels, wind turbines, and batteries have all significantly dropped in price in the last decade.
I don’t think the assumptions in the report are reasonable. Fully dispatchable renewable with sufficiently deep buffers against dunkelflaute is prohibitively expensive(BESS 120 usd/kWh) , and this ruins your EROEI which is already marginal to start with.
Gonna need some words for those letters

Renewable energy sources that can be switched on and off at will with sufficiently deep buffers against lulls in generation are prohibitively expensive (Battery Energy Storage Systems cost 120 usd/kWh) , and this ruins your Energy Return on Energy Invested ratio which is already marginal to start with.
Battery energy storage system and energy return on energy invested. Some use energy cost of energy, in percent.
Good
