It isn't all sunshine and warm breezes. Renewables obviously have the intermittent power production issue, and they have to be where the energy is, not where it's being used. But ignoring large scale batteries (maybe someday we can just use graphene!) being a major issue, there's other things. For example, an energy grid must be balanced in terms of real power (how many watts are being generated/consumed) reactive power (motors and generators produce and consume this, it needs to be balanced) and frequency (for your AC electronics!) Wind farms traditionally consume a lot of reactive power. This is bad because a wind farm can become incompatible with the rest of the grid as the wind changes. For those who don't mind some science,
here's an old link. Nowadays, there's a new type of wind turbine design (doubly-fed induction generators or DFIGs) that gets around this entire problem. But my point is not all electricity was made equal!
Every power source requires the industrial fuel extraction operation, and the simple scale of coal extraction or the nastiness of rare earth processing probably dwarfs uranium mining per MWh. Power plants themselves barely take up land on any appreciable scale (all plants need space, but they aren't like the size of farms or cattle ranches.) All the nuclear waste ever produced could be stored on a small amount of land - it's just doing that safely. And, thanks to advances in reprocessing, a lot of the time its best to keep the stuff on site- where the nuclear expertise and containment talent already is. So that's handy.
Nuclear plants themselves are a PITA to build because in the west, we just don't do it often anymore and we've added extensive regulations and red tape and political pressure. Not saying all of that is bad. But if for example, the USA built only nuclear reactors instead of coal turbines, people would get good at it, the regulatory agencies would have streamlined the process (especially for modern designs that can remove the risk of meltdown) etc etc. The entire lure for a big utility company is that nuclear can be very cheap per kilowatt hour- cheaper than coal. It's a long game. Otherwise they never would have built them to begin with, and you wouldn't need to publicly pressure gov'ts to close them- they'd all decommission willingly! France is a great example.
Hydro is probably the best form of energy out there, it's just limited because you need the waterways to support it. We try.
