1. The amount of land or sea, which latter makes for a dearer installation but is much easier to find in densely populated countries like the UK. 2. My understanding is that, sure, you can't have a grid that runs purely on wind, but you can go a lot higher than we currently do without much trouble. The issue with massive new nuclear is that outages can take a sizeable percentage of your generation off-grid unexpectedly at a moment's notice (Hinkley will I believe represent 7% of UK grid capacity), which in a sense is a worse intermittency problem than you get with renewables (which tend to ramp up and down more smoothly and broadly in line with weather forecasts). Also, battery storage can help.
