note: in the second chart below comparing the Levelized Cost of renewables versus the marginal cost of conventional energy sources is a bit apples and oranges, but the overall impression the report gives seems about right.
From Lazard, October 28, 2021:
Levelized Cost of Energy
Lazard’s latest annual Levelized Cost of Energy Analysis (LCOE 15.0) shows the continued cost-competitiveness of certain renewable energy technologies on a subsidized basis and the marginal cost of coal, nuclear and combined cycle gas generation. The costs of renewable energy technologies continue to decline globally, albeit at a slowing pace, reflecting reductions in capital costs, increased competition as the sector continues to mature and continued improvements in scale and technology.
Additional highlights for LCOE 15.0:
When U.S. government subsidies are included, the cost of onshore wind and utility-scale solar continues to be competitive with the marginal cost of coal, nuclear and combined cycle gas generation. The former values average $27/MWh for utility-scale solar and $25/MWh for utility-scale wind, while the latter values average $42/MWh for coal, $29/MWh for nuclear and $24/MWh for combined cycle gas generation....
