A point that I've made a few times in various places is simply this.

ALL POWER POLLUTES.

Coal pollutes the air and land. Oil - air and water. Gas - air. Nuclear - hazardous waste. Hydro - flooded valleys. Wind - kills the birds and spoils the scenery. Wood - loss of habitat etc.

It all pollutes somehow. All we get to choose is what we pollute, where, and in what way.

Personally, I prefer to pollute in a manner which is at least reversible in the long term. Wind - once dismantled, the effects are largely reversed. Hydro - also largely reversible over a period of a few decades. Fossil fuels and nuclear - irreversible in practical terms (eventually maybe, but not within a few thousand years).
