>companies you think are poised well for the future

anybody installing wind turbines or solar panels will be busy for years

In the past century hydroelectric was the only renewable build on a large scale. This changed when larger wind turbines and solar came up. Today here are already regions like northern Germany with net renewable greater than 100%. Mainly wind and solar.

Value of 1MWh varies greatly, depending on demand. This is bad for atomic power plants. They can not be quickly shut down if there is low demand. As a result value becomes negative. You have to pay customers to buy your energy. A wind farm can be shut down quickly if needed. So they will never make a loss.
Wind is for free, so after pay off construction a wind turbine becomes some kind of magic money printing machine. Well, almost. There is still maintenance.

Your 95% for nuclear is super optimistic. In reality atomic reactors are often shut down for several weeks, older plants even months. If there is a drought and not enough water for cooling power output has to be reduced. As a result you get more like 50%. This is still more then on shore wind, but less then off shore.
