First New Nuclear Reactor In a Decade On Track 575
dusty writes "Plans to bring online the first new US nuclear plant since 1995 are on track, on time, and on budget
according to the Tennessee Valley Authority. TVA had one major accident with a coal ash spill of late, and one minor one. The agency has plans and workers in place to have Unit 2 at Watts Bar, near Knoxville, online by 2012. Currently over 1,800 workers are doing construction at the plant. Watts Bar #1 is the only new nuclear reactor added to the grid in the last 25 years. From the article: 'TVA estimates the Watts Bar Unit 2 reactor every year will avoid the emission of about 60 million metric tons of greenhouse emissions linked with global warming. ... TVA began construction of Watts Bar in 1973, but work was suspended in 1988 when TVA's growth in power sales declined. After mothballing the unit for 19 years, TVA's board decided in 2007 to finish the reactor because it is projected to provide cheaper, no carbon-emitting power compared with the existing coal plants or purchased power it may help replace.'"

I consider myself a sane and pragmatical environmentalist. That is, I believe that we shouldn't crap all over the place just because it's easy and convenient for us to do so today, disregarding the consequences of those actions tomorrow. Thus, I believe that we should gradually reduce the use of fossil fuels (i.e. as fast as possible, but without collapsing our economy and inducing quality of life decrease).
On the other hand, I still believe that needs of humanity come first, and that nature (and, in general, world around us) is something that we should use towards our goals and preserve for the sake of self-preservation; and not something inherently valuable in and of itself, or a god to worship. Thus, I do not support significant scaling back of our energy use - most of it really isn't excess, but is required to maintain our present living standard. Reducing energy consumption would require scaling it back very significantly, and I do not want to see that happen. We can definitely try to trim consumption down where possible, by using more energy efficient machines and technologies (such as those nifty insulated houses that leak very little heat). But in the end, this is still a drop in the ocean.
The only way I see to reconcile these two viewpoints is to embrace nuclear power (and in perspective, when they get it to work, fusion). It's reasonably clean - yes, there's waste, but that can be fairly easily contained and controlled. It is powerful enough to sustain our energy use, even extrapolating future growth. And it is going to last for very long, long enough to research the next step (be it fusion or something else).
Nothing else cuts it. Not solar, not wind, and not tidal. I fully support their use wherever possible, but they quite obviously aren't enough to cover our needs without scaling them back significantly.

2. Covering signifigant portions of any land mass in solar panels (solar farms) leads to serious erosion problems and other issues that are not widely publicized as a large problem. It is a large problem, so much so that some solar farms are only producing at about 60% capacity due to equipment failures caused by panel foundations shifting and wind issues. Read the article in Wired.
3. Wind farms can not adequately provide enough power to the grid to support everyone. In severely windy areas it can cause serious power spikes that our current power grid cannot handle potentially causing large scale outages. It is also worth noting that if you have an unusually non-windy month, your refrigerator might not turn on some nights. That sucks.

Ionizing radiation is inherently hostile to carbon-based life. That's the bottom line. No, it won't kill you instantly, but it's there and it's not part of the normal Earth ecosystem. To make fission power work, you have to find ways of blocking, neutralising, or containing that radiation. You have to take it out of the eco-loop somehow. You have to build technological walls and ghettos, create danger zones, invent safety protocols. None of which are needed with other forms of power, to the same extent.
