And you're just ignoring the fact that certain political decisions, such as those related to fuel, play a role in electricity costs. Hindering oil production in the US being an example. Stopping pipelines. Making it harder for ships to transport in goods related to these things using stupid laws. There are so many factors at play that distort economics, usually caused by government or increased demand on an infrastructure or supply that hasn't improved. Hence the need for more efficient energy production (nuclear).
