LCOE (total, incl. CAPEX, in USD per MWh):
coal 82.6, combined cycle 39.9, advanced nuclear 81.7, geothermal 37.6, biomass 90.1, onshore wind 40, offshore wind (that one was a surprise, since offshore wind should be quite cheap, mainly driven by capital cost of 104 USD per MWh) 105, solar 33.8, solar hybrid 49 and hydro 64.
Variable cost (same as above):
coal 23.7, combined cycle 27.7, adv. nuclear 10.3, geothermal 1.2, biomass 30, onshore wind 0, offshore wind 0, solar 0, solar hybrid 0, hydro 4.1

Nuclear power: about 10% of global electricity generation ( https://en.wikipedia.org/wiki/Nuclear_power#Production ) which is about 22% of final energy ( https://en.wikipedia.org/wiki/World_energy_supply_and_consum... ). Therefore the nuclear fleet (~440 reactors) now provides a meek ~2.2 of final energy. To reach about 11% implies building 2200 reactors (good luck with this), and would only let known uranium reserves provide each reactor for ~40 years, with few hopes towards the discovery of new reserves ( https://news.ycombinator.com/item?id=38288706 ).
In such a context uranium will become more and more rare, and therefore more and more expensive... and strategic (keyword: 'embargo').
