Water Shortage Shuts Down TVA Nuke Plant

I posted this yesterday at Daily Kos – under a different title “Nuclear is Not the Answer”.  The pro- nuke shills immediately descended upon the diary and I’m only now coming up for breath.  Maybe some folks here will read it for what it’s about – our current (and future) shortage of cool water is a major problem for nuclear plants.

Here’s the diary:

Nuclear power is not the answer to global climate change. Other than the safety issues connected to nuclear waste, which are pretty well-publicized, there is a major problem with thermal load, which is not so well known.

Nuclear plants need cool water for cooling.  Hotter water temperatures in the Tennessee River this summer caused TVA to suspend operations at their Browns Ferry Plant.  Browns Ferry is downstream from 3 other TVA nukes which had already heated up the river to a point to prohibit further heating.

France and Germany have had the same problem – in the 2003 heat wave.  The rivers on which their nuclear plants were built were heating up beyond their environmental agenies’ standards for aquatic life. A choice had to be made between nuclear power and the health of their rivers and aquatic life. 

As folks who read the great diary this weekend on Atlanta’s water shortage must recognize, with climate change and rising temps, the cool water necessary for nuke plants will be a scarcity

Doing it for Ourselves 1.3: Passive solar

Let the sunshine, let the sunshine in, the sunshine in

Let the sunshine, let the sunshine in, the sunshine in

Let the sunshine, let the sunshine in, the sunshine in

Oh, let it shine, c’mon

Now everybody just sing along

Let the sun shine in

Open up your heart and let it shine on in

When you are lonely, let it shine on

Got to open up your heart and let it shine on in

And when you feel like you’ve been mistreated

And your friends turn away

Just open your heart, and shine it on in

What is Passive solar? How does it differ from active solar technology? What are the benefits of passive solar technologies? Read on to find out.

By the way, this weekend marks the National Solar Tour by the American Solar Energy Society. You can check to see if there are any tour events in your area here

Mark Your Calendar – National Solar Tour

Every fall, chapters of the American Solar Energy Society sponsor home tours around the country.  This year, most of the tours are on October 6, but some are earlier, such as this coming Sunday, September 23, in San Francisco.

It’s a great opportunity to find out what kinds of alternative energy measures people have adopted in your local area.  For example, there’s nine throughout the state of Colorado.  There’s literally 100s of them nationwide.  Unless you’re in the Dakotas, Wyoming or West Virginia (West Virginia??); there’s one in your state, and also in Puerto Rico.  Bowling Green, Kentucky’s having its “first annual” solar home tour this year.

Here, too.
