Saving Energy Without Derision

George Maschke writes "Saving Energy Without Derision (5 mb PDF) is a new (and free) e-book by former Sandia National Laboratories senior scientist Dr. Alan P. Zelicoff. This book is intended to be a real-world, no-nonsense, thoroughly documented collection of easy-to-implement recommendations to help the average thoughtful person to pick the 'low-hanging fruit' of conservation and renewable energy. The author is after the easy 75% of actions we can all take (but almost uniformly ignore) that most certainly make a difference in energy costs (after all that's what most people care about) and adjuring a bit of unnecessary adverse impact on the environment (which a few folks actually think is important beyond the mere dollar valuation). The author welcomes comments and intends to continuously update the book (consistent with readership interest) and address many new topics. For example, next on his list is an analysis of the economics and scientific basis of fuel-cell vehicles powered by hydrogen. (Bottom line, he maintains, is that it's a cruel hoax and energy disaster, and far less useful than, for example, heavy hybrid automobiles that get about 50 - 60 miles on an electric charge alone -- which accounts for more than 85% of driving in the US and elsewhere on a daily basis -- and which are available now.)"

It's a nice thought..

[JohnnyKlunk]

I beleive in this stuff, I really do.
I can't rtfa as it's /.'d currently - but we all know the content - "Install insulation, drive a fuel-efficient car". Lovely, great thought - but how do you put it into practice. I don't own a car, I make a point of not owning one but how do you convince Mr Tinyknob in his suv-sports-environment killer to drive something fuel efficient? He's never going to impress people any other way.

OK, I'm being harsh, but it's fair. I take all sorts of precautions to leave a fair planet for my (currently) 5 week old daughter, but I frequently wonder what the "£$%ing point is if the guy at the next desk drives 500 miles weekly in his V8 5litre penis extension because he's got no self esteem what-so-ever?

You forget about nuclear power

[argoff]

You are forgetting that in a hydrogen society - there is now room to bring nuclear power back into the picture. Now people have the potential to create hydrogen on a vast scale far away from any place that might have political fallout.

In spite of all the bad press, the fact is that nuclear is still the safest, cheapest, and most environemtally friendly energy source ever created. IMHO, it's bad wrap had far more to do with its threat to OPEC then it ever had to do with safety or radiation.

Re:You forget about nuclear power

[Phanatic1a]

Burning coal produces waste that remains toxic forever. Half-lives come and go, but arsenic is forever.

Nuclear power is environmentally friendly because the amounts of waste you're talking about are incredibly low for all the energy you're getting out. You're looking at around 23 tons of high-level waste per megawatt of plant per year, at a 91% duty cycle. And this is dense stuff, by the way, so volumetrically it's a very small amount. It's also in a relatively convenient-to-handle form; it's not discharged into the air or the water.

Compare that to a coal plant, where you're generating 1.5 million tons of ash per megawatt of plant per year, which is vastly more polluting, and that's not even considering the CO2. For every single kilowatt-hour of energy you get fro burning coal, you produce a kilogram of CO2. So if you run your megawatt coal plant on a 70% duty cycle, generating 8800 megawatt-hours,you dump 4400 tons of CO2 into the atmosphere.

And that fly-ash you're making is toxic forever. It's caustic. It's filled with heavy metals. Both in terms of mass and volume you've got orders of magnitude more of it to deal with than you would if you went nuclear. And if you're concerned about radiation, well, burning coal releases uranium and thorium isotopes right into the atmosphere; coal has up to 10ppm of uranium in it. Since 1937, burning coal in the United States alone has dumped 145,000 tons of uranium and 357,000 tons of thorium into the air; that radiation's just as real as the stuff in nuclear waste, and the cancers it causes and the people it kills are just as real.

Let's pick a random small country, like the UK. From what I can find, they have a generation capacity of 361 terawatt-hours per year. 8765 hours in a year, 91% duty cycle, so 8000 hours. To produce 361 terawatt-hours in 8000 hours, you need 4500 megawatts of plant. So if the UK went all-nuclear, they'd generate just a bit over 100 tons of high-level waste per year.

They could take that, put it in thin-walled steel drums, and dump it right to the bottom of the North Sea, and they'd be doing vastly less environmental damage than they're doing now, by getting 74% of the electricy from burning fossil fuels and dumping 614 billion pounds of CO2 into the air every year.

That 145,000 tons of uranium the US has dumped into the air just by burning coal, since 1937? Well, that's 10440 tons of U235, which if you fission it (okay, with perfect effiency. This is just to illustrate a point) produces 17.6 kilotons of energy per kilogram. If you fission 10440 tons of it, you end up with 193 petawatt-hours. That right there's the electrical needs of the entire UK for 500 years, at present rates of consumption.

By all those metrics is nuclear power environmentally friendly. It's utterly ridiculous that we're not embracing the technology and making our electricity the right way.

Re: "Derision" felt for the "Anti-Consumer"

[travler]

Some who tries to conserving energy may be said to be an "anti-consumer", because if one conserves energy, then that person is not being the best possible consumer.

The reason such persons are objects of derision is because we Americans have been socialized to be the best possible consumers we can be: years of corporate media propaganda have been directed towards encouraging us to spend as much on food as possible, as much on transportation as possible, as much on healthcare as possible.

I don't care about anyone being an 'anit-consumer'.

Consume less all you want I really don't mind, in fact since less demand = lower prices I'm all for it.

The problem that I personally have (and I think that most anti-green/socialist types have) is that the only way they (enbormentalists/socialists) can force their utopian agenda on the rest of the world is by government action (people with guns forcing me to do stuff I don't want to do).

In other words it is a freedom issue. I think we all want clean air/water, good health care, nice work environments, etc. The argument is how to get there not on what the goals are.

The way I see it enviromentalists/socialists are objects of derision (at least in my mind) because they either truely don't understand how the world works (they want stuff for free as in free beer with no thought on who pays the bill) or they do know the cost and are more than happy for me to pay it for them even though I don't agree with their plan.

Socialism (and most environmentalist groups I've read about seem to fit here too) doesn't work because you have to have a strong central government forcing people to behave in ways they don't want to. It is inefficient and the people who live under it feel oppressed. You don't get good results for society as a whole or for individuals within that society. Everyone loses.

All of this is my opinion but perhaps you will find it usefull to understand how the 'oposition' thinks. It isn't that we don't want those things it is that the price of the system that you are advocating (my freedom) is too high.

Half-life versus stable

[2901]

Some industrial waste is stable. Arsenic waste from tin mining, mercury waste from gold mining, cadmium from discarded rechargable batteries, beryllium from heat transfer uses.

None of this stuff decays at all. Waste that just goes away if you wait long enough looks good by comparison.

More significantly, there is an inverse relationship between half-life and activity. When you take out your spent fuel rods there is some U235 left, with a half-life of 700 million years, and also Strontium 90 with a half-life of 29 years. The Strontium 90 with its short half-life is releasing its energy quickly. This contributes to making the spent reactor very radio-active and very dangerous. But 290 years later 99.9% of the Strontium has decayed. Meanwhile the Uranium, which is releasing its energy too slowly to be dangerous, clouds the issue of how long reactor waste lasts. Long after the waste has ceased to be dangerous, it remains slighty radioactive.

One mind boggling point is that Uranium used as reator fuel supplies about a million times as much energy per unit weight as coal. Coal is a fairly pure product and contains only about 1.5 parts per million Uranium as a contaminant. So about 50% more Uranium goes up the chimney of a coal fired power station as goes into the reactor of a nuclear power station.

That is amusing in a way, but not very important, because the Uranium that goes into a reactor isn't dangerous anyway. The worry with nuclear power is the transmutation of Uranium into short lived, highly radioactive isotopes of other elements. However the point remains that the quantities of waste involved in nuclear power are very much smaller than the quantities involved in producing power from chemical sources.

Why do I care? I was six years old at the time of the Aberfan Disaster, the same age as many of the 116 children who died, suffocated under a slurry of waste from a coal mine after the collapse of a waste tip. The TV pictures of the time showed the gable end of the children's school. It was just like the one I attended and this upset me.

I have never forgotten that quantity is a quality of waste. The waste from the coal mine might as well have been composed of perfectly safe, inert materials. It would not have made any difference. The children were buried and suffocated because there was so much of it, not because it was "dangerous" in the sense that the word is used today.

by what metric is it considered environmentally friendly?

Quantity.
