It's being framed in terms of nuclear power because the original arguments that led to this situation were also framed in that context. The anti-nuke movement of the last century directly resulted in this situation by preventing the construction of new nuclear power plants and in some cases cancelling existing ones such as the Zwentendorf in Austria[0][1][2]
Those decisions made almost half a century ago were shortsighted, emotional, and led by ideologues lacking the ability or the desire to realize the consequences of their actions which we are now reaping in the form of an energy crisis and an environmental crisis that has become much worse than it need have been.
