And what makes you think fusion will actually turn out to be that cheap? People said the same thing about fission, but it's turned out to be quite expensive, and the technology is likely to be very complex. If you calculate how large area of photovoltaics you can build for the price of developing and building a fusion reactor (not that anyone has any idea what this cost will be), I suspect you'd get a lot of it.

And what makes you think fusion will actually turn out to be that cheap? Because fusion scales well. With time, everything limited by technology becomes cheap as technology advances. There are no fundamental problems or limits in fusion, just practical problems. Fusion has never received the amount of funding it should have received. How long did it take ITER to get the measly 10 billion dollars required? As for fission: the all important difference is that the fuel for fusion is much easier to get, is unlimited and the garbage that gets left behind isn't nearly as much of a problem. Moreover, there is no risk of blowing up half the nearby city and irradiating the area for the next 100K years. Fusion and fission are incomparable as for their ability to provide energy.
