> For renewables to be renewable you have to make the solar panels and turbines and storage systems from the energy generated by solar panels and turbines
This is only true if you're going for some pedantic definition of renewable energy where it only counts if you're at 100%. Which, this being HN, is the kind of thing I expect but...
The reality is different: we need to reduce the impact of climate change by any means necessary since are already in a state of climate emergency. If we calculate that using fossil fuels to build solar/wind turbines/wave energy/etc. and then using those to power homes will be a net negative in global emissions, then we should do it. We can build the next generation using renewable energy.
Worrying about whether this fits some definition of renewable energy is just a distraction. Renewable energy is not the end goal, tackling climate change and reducing pollution is.
I don't think you answered the argument there, merely suggesting it's fine to kick the can down the road because "emergency now!"
First, we need to look at where renewables are being used and if they're actually in the areas of greatest pollution, i.e creating a net reduction rather than just meeting a government number.
The relevant metric is joules of forcing avoided and joules of forcing avoided per dollar. Nuclear is very rarely a good choice by this metric even compared to changing coal for gas.
