It's relatively easy for one person to source clean power themselves, just means that technically your payment goes to a wind farm instead of the grid as a whole, but really doesn't change much for the grid. It's much harder for everyone to get clean power, then you get very advanced issues balancing the variable nature of renewable generation.

In this case I believe it means carbon-free, so Nuclear is still technically viable though very unlikely any new Nuclear will be built. Will be mostly existing hydro, nuclear and geothermal with new solar & wind phasing out gas plants.
