I think what a lot of people against renewables (particularly conservatives) don't grasp is that energy independence absolutely IS a national security issue. Renewables by their very nature give a nation more energy independence.    
Look at Europe right now, the Ukrainian invasion caused Europe to correctly stop buying Russian natural gas (and or Russia stopped selling), prices skyrocketed on the remaining, and it has caused instability, may cause deaths, and certainly caused economic harm.    
Migrating from natural gas heating in homes/businesses to efficient electric heat pumps, and then using renewables in the grid creates a macro-stable energy system. You then supplement renewables on the grid with whatever cost-effective alternative fuel is available (natural gas, oil, nuclear, et al), creating a micro-stable grid too.   
The fact that renewables aren't discussed as a national security issue is strange frankly. Water access and energy, they're absolutely vital for national security.
“South Australia has just chalked up what is undoubtedly a world first – a run of more than 10 consecutive days over which the average production of wind and solar accounted for 100 per cent of local demand.
No other gigawatt scale grid in the world has come close to this amount of “variable renewable energy”, or for such a long time.” >

Costa Rica had it close >

Unfortunately Costa Rica is mainly hydro.  They don't really seem to be ramping their solar or wind all that much. 
Share of electricity production by source, Costa Rica >

That’s still renewable energy, so it could be worse
