Wind and solar may be a loser to nuclear, but that doesn't mean they should be abandoned. Every power source we can imagine should be developed and used. We just need to be practical about its viability. Wind and solar do not provide reliable steady power, but they both can be used to supplement other power sources. We only have a problem with wind and solar when we put too much reliance on those unreliable sources. There are peak times during the day when the grid is used more often than other times. It is during those peak hours when wind and solar can be included with the rest of the grid to help offset the load.
Nuclear is also not the panacea that it was made out to be in the video either. You only want to place nuclear on stable ground, beyond the reach of any tsunami. Which eliminates coastal areas and places like Alaska, California, Italy, Turkey, southeast Asia, and any other geologically active location.
We should also be looking into using thorium (Th-232) molten salt reactors. They present a higher risk of gamma radiation and could potentially result in producing U-233 if protactinium (Pa-233) is not removed during the fission process, but produces radioactive waste with a much shorter half-life than uranium nuclear reactors. They is also have no possibility of "melting-down" a thorium molten salt reactor, like there is with uranium nuclear reactors.
Hydroelectric and geothermal power sources also should be included where ever it is practical to build them. The city of Anchorage, Alaska, for example, is primarily powered by three natural gas power plants, a hydroelectric dam, a wind farm, and a coal power plant. No solar is used, however, there are plans to construct a 5 MW tidal generator in Cook Inlet that will be used by the city. Anchorage is using every energy source at its disposal that is practical.
The point, however, is to develop stable, reliable, and cheap power sources, while using renewable energy sources - where they are cost effective - to supplement the reliable sources. Renewable energy sources should never be allowed to become the primary energy source, like California, Germany, the Netherlands, and other nations are attempted to do.
