I don’t know about initial costs, but the main problem with wind/solar is they cannot be scaled up/down on-demand. The depend on the weather and that does not align with energy demands throught the day.
As long as we cannot store energy at-scale, we will have to rely in another source of energy we can ramp up/down depending of the energy demands (being fossil fuels or, preferibly, nuclear)
That’s a taking point that wasn’t very true in the 70s and certainly isn’t close to true now, there are endless methods of balancing a renewables grid for constant power involving endless options for continuous generation methods (solar thermal especially) or battery storage (chemical, gravity, etc) and load balancing using at-peek tied industry (especially e-fuel manufacture)
There’s also a lot of stuff like tidal generation which is hugely promising and drastically underfunded, certainly compared to nuclear.
