What is the difference between Chernobyl, Fukushima and Texas blackout

 All of these are catastrophic events with human lives lost. The Chernobyl nuclear reactor runaway is fully a personal responsibility. A nuclear reactor is not a good place for experiments. Such experiments are prohibited now. Fukushima is a technical problem with risk underestimation. This is an example of a black swan or a statistically infinitesimal event out of normal distribution. Technically, one can easily resolve this issue.  Texas blackout in February 2021 is a new type of event. There is no technical solution yet. Renewable energy sources are fundamentally unreliable and the interaction of the state-of-the-art windmills or solar panels with the potential weather outliers is inevitable in the future.  People will die in progressive numbers with the growing part of RES (however, hydropower and nuclear power are RES as well).
