Nuclear power is the middle ground between moving away from coal, oil and gas to solar, wind and water power.

The problem about green energy sources is that they require a hell of a lot more resources going in than nuclear and fossil. Solar and wind farms require more workers per gigawatt generated, and a hell of a lot more land.
As you require more and more energy to generate/collect energy, it obviously means that you have less energy in the end to play around with... meaning more expensive energy, more workers, and a less complex society.

The end result of solar/wind is that the cost per KWH is significantly higher than any other source that we know of. My brother had access to a local wind power company's balance sheet. According to him, it would take 70 years to pay back the cost to install and maintain the plant if they were to sell the power at current market rates.
Not only that, most solar we talk about (in the US) is solar thermal, and not just solar panels. Solar thermal generates a lot more power per square foot, which is somewhat more economically viable than solar panels, but such systems require massive re-distribution of water which in and of itself is a major ecological concern.

so f'ing the entire world is fine because it cost too much. I see your logic

Costs have massive implications. The number one way to reduce poverty is to reduce the cost of energy, for example.
Without cheap energy, we have nothing. You have any idea how much energy is required to mine metals? Or to provide you with a meal (growing -> transportation -> producing and packaging -> transportation -> retail -> transportation -> storage and retail -> transportation -> home and final preparation (perhaps refridgeration, or freezing, cooking)) ? In many parts of the world, cheap energy is required to keep people from freezing to death. Others, without energy-intensive desalination, have no water to drink. Huge amounts of energy are also required to provide you with healthcare, education, etc, etc. And this is before we get to the obvious stuff - lighting homes, powering electical consumer goods, etc.
What costs us a couple of dollars today in a meal that can be prepared in about half an hour would be beyond the finest meal a king could have afforded to enjoy two hundred years ago, with a hundred men working on it. This is only possible through cheap energy.
So, yes, until a cheap energy source can be found: fuck the world. It's either that, or fuck humanity.
