This is a technical question way beyond my knowledge.
For example, you don’t mention whether spending the same amount of money on nuclear or on solar/wind would produce the same amount of energy. Maybe we should choose the cheaper thing, per unit of energy produced. Also, I don’t know whether e.g. solar panels do not require some scarce ingredient, so if you try to build too many of them, their price goes up.
