Agreed. I think fusion power would be great, but the sales pitch of 'limitless free power' just isn't true. The thought experiment I use is this: Let's imagine coal is magically free in every way. How does my power bill change? The answer is "barely at all" because the cost of utility electric power is mostly in distribution. We pay around 30c/kWh while the wholesale energy price is more like 2c/kWh.

It'll still make a difference in large scale energy intensive stuff, like desalination, aluminium refining, etc. but the average punter is going to save a lot more by installing solar panels.
