Beat up the economists

Filed under: Social — cec @ 1:19 pm

It’s apparently “beat up the economists” week and no one thought to tell me in advance.  Over at Crooked Timber, Daniel Davies posts about Greg Mankiw’s recent NY Times editorial and suggests that the reason economists are so patronizing is bitterness over being stuck in a low paying academic job whose sole purpose is to justify the inequities in a capitalist system.

In Scientific American, we have Rober Nadeau’s editorial on the problems with the views of economists.  Nadeau notes that economics is a social science that tried to pattern itself after physics.  Unfortunately, a) it used 19th century physics and never updated itself as the physics changed; and b) economists never realized that they can’t treat people as elemental particles.  Nadeau goes on to note some of the basic assumptions made in economics that don’t stand up.

In the interests of piling on, I’ll say that I agree with Nadeau, but think that he doesn’t go far enough.  Social sciences are extremely valuable and in a certain sense are much more difficult than the so-called hard sciences like physics and chemistry.  People don’t behave the same way, you can’t always re-run an experiment, etc., etc.  However, in the academic world, the hard sciences have been able to claim greater status because they are more rigorous and because, in essence, they are simpler.   So it’s not surprising that economists would want to claim the status of hard, reductionist, sciences.  However, it’s worse than that.  We expect physicists to explain the world.  We expect economists to make predictions and tell us how to fix things.  We’ve taken them out of the role of reductionist explainers and put them into the role of designers.

In other words, economists are social scientists with physics envy who are called upon to do the work of engineers.  It’s amazing the economy isn’t in worse shape than it is.  🙂

Power company balanced bill plans – banned

Filed under: Social — cec @ 7:43 pm

As mentioned last month, the North Carolina Utilities Commission has banned the expansion of Progress Energy’s Balanced Billing Plan and Duke Power’s Fixed Payment Plan. These are the plans that charge you roughly 11% in order to have a guaranteed power bill. Unfortunately, it’s not a full ban, it’s just a prohibition against enrolling any new participants. The reason for the ban? [drum roll please] The plans encourage participants to increase their power consumption.

Welcome to your crappy low-rent future

Filed under: Social — cec @ 2:37 pm

Last week I was having lunch with a colleague (of sorts) and we were on the topic of the economy, outsourcing of jobs, etc. I mentioned that we were living in, what I’ve taken to calling, a crappy low-rent future*. He pointed out, and I agree, that this is largely because corporations have broken the social contract. It turns out he had been reading Robert Reich’s “Super Capitalism” while I had been reading “The Global Class War.” In their own ways, each of these books tells the story of how corporations from the end of the WWII with the New Deal until the late 1970s were bound by something of a social contract. Corporations recognized that their customer base was their employee base and that while you might not want to pay your employees, not doing so would spiral out of control so that your own customers couldn’t afford your products. Corporations began to slip the social contract in the late 70s with the Regan Revolution. The trend continued in the 80s and 90s as companies began to achieve transnational status: i.e., their customer base and their employee base were no longer the same. NAFTA and the follow-up “free” trade agreements accelerated this trend by allowing companies to shift labor and production to the places where it was cheapest without actually requiring labor or environmental standards that would level the playing field.

These “free” trade agreements began a great race to the bottom. The factory farms of the U.S. put hundreds of thousands of Mexican farmers out of business. Seeking work, these former farmers immigrated to the U.S. to work our farms and to clean our hotels and build our houses. The glut of relatively cheap labor, accompanied by a disgraceful minimum wage in the U.S., led to an increasing large number of people whom have dropped out of the work force. As an aside, don’t be fooled by the unemployment rate. There are two ways to decrease the unemployment rate, you can either increase the number of working people or you can decrease the size of the labor force. Over the past 7 or 8 years, we have not increased the number of working people, but we have decreased the size of the labor force. One simple rule of thumb: every month when the number of new jobs created is less than 150,000 or so (the increase in working age population times the current participation rate), the unemployment rate *should* get worse. If it doesn’t, it’s because more people have stopped participating in the work force.

People often talk about democracy and capitalism as if they were one and the same thing. News flash – they aren’t. For some time, the Chinese have been interested in capitalism as a way to raise living standards in order to keep democracy out of their government. To date they’ve been pretty effective at it, using the tools of capitalism to build instruments of oppression (e.g., the Great Firewall of China). In the U.S., we’ve had both democracy and capitalism for so long that we don’t recognize the differences. However, the founders of the country did recognize the differences. The founders were concerned that naked capitalism would evolve into aristocracy which would kill a new democracy. At times, that prediction has almost come true. That was certainly the case in the first gilded age. Fortunately, FDR’s New Deal pushed back the growth of that aristocracy up until the late 70s. Now we are once again seeing the results of raw capitalism and its ability to direct the efforts of the government to its own end – away from its founding purposes (protecting the rights of citizens).

What bothers me most about this crappy low-rent future is not just that things are worse for people that work for a living; it is the opportunity cost of spending the past three decades increasing corporate profit at the expense of investment in the future. Some of that investment would just have been growing wages at the same rate as corporate productivity, instead of rolling the productivity gains into corporate profits. If we had done that for the past 30 years, you would probably be earning more than twice your current salary. I believe that a true wage increase (instead of just keeping up with inflation) would allow people to think about other important issues such as the environment.

If we had spent the past 30 years focusing on the environment, in particular, developing alternative fuels and higher efficiency cars (or better yet, high efficiency, convenient public transportation), we wouldn’t be seeing the record high oil prices of today. Considering how little (relatively speaking) we’ve put to nuclear, solar and wind power, we have made a lot of progress. I was reading where some engineers have found a way to use ink jet printing technology to print solar cells. If we had been working on this for 30 years, solar power would be cheaper than coal/oil power generation. In just the past 5 years or so, we’ve seen a tremendous increase in the efficiency of wind turbines. They are able to produce power in lower wind conditions reducing the overall cost per kilowatt hour. I also don’t have a major problem with nuclear power, but having sat on our hands for 30 years, it is the Europeans who have all of the experience with it; but if we had spent time and money developing nuclear, we could have had a nice bridge from fossil fuels to renewables. And of course, what can you say about cars. After the oil embargo of the early 70s, we passed the CAFE standards and achieved their goals. But after the crisis passed, we stopped paying attention and as people began to drive trucks and SUVs as personal vehicles, we saw the average fuel economy in the U.S. drop. As an example, K is the original owner of an ’87 Volvo which gets about 25 mpg and I own a 2000 Toyota that gets about 32 mpg. I’ve seen new cars advertised that are less fuel efficient than either of our cars! We developed hybrid technologies in the late 90s and ten years later, there is minimal penetration into the broader car market and about half of the hybrids out there are using the technology to boost horsepower, not efficiency. There is no reason we couldn’t have cars today that get 100 mpg. No reason except that it hasn’t been a concern for the past 30 years.

The world has a limited supply of fossil fuels. We can argue about how large that supply is, but if you don’t think it’s limited, then you haven’t thought it through. That supply of fossil fuels was not all bad. We would have never achieved a technological base without it – it is easy and cheap power. However, we should have used that limited supply and the technological base we built from it to develop new technologies that are unlimited (or at least only limited by the life of the sun). We should have developed nuclear power and hybrid cars in the 70s and 80s as a bridge to completely renewable power and electric cars. But instead we’ve squandered much of the “gift” of fossil fuels and in the process are pumping enough CO2 into the atmosphere to significantly alter the temperature of the planet.

I don’t have much of a point here except to vent about being stuck in this crappy low-rent future. I don’t want flying cars, I want fuel efficient cars. I don’t want billionaires, I want everyone to have enough to eat. I don’t want global warming, I want renewable fuels. And I don’t want trade deals than protect corporate profits, I want trade deals that protect the environment. My guess is that it’s probably too late to avoid many of the problems we can see on the horizon. We’ve got billions of third-world peoples looking for a first-world lifestyle. We don’t have “clean” technologies for them, so we’re going to have billions more people burning coal and oil, making the global warming problem even harder to deal with. The U.S. economy is up to its eyeballs in credit card and mortgage debt, in part due to the lack of wage increases for 30 years. We’re starting to see the effects of this in the mortgage meltdown and the upcoming (ongoing?) recession. I’m sure we’ll muddle through, but that’s about all it’ll be.

In short, welcome to your crappy low-rent future. **

Who could have guessed?

Filed under: Security,Social — cec @ 7:27 am

Gee, nobody could have predicted this I suppose:

The FBI improperly used national security letters in 2006 to obtain personal data on Americans during terror and spy investigations, Director Robert Mueller said Wednesday.

Admittedly, Mueller goes on to say that the reports were prior to new policies being put into place, but somehow that doesn’t make me feel much better.  It’s things like this that have always made me very nervous about partnerships between law enforcement and industry.  I’ll try to post something about InfraGard one of these days.  It’s a little scary in its own right.

FISA extension and telecom amnesty

Filed under: Social,Technical,University Life — cec @ 11:10 pm

Few people have been on top of the extension of FISA like Glenn Greenwald. As a quick overview for folks that haven’t been paying attention to the issue:

  • Late last year a real potential problem with the Foreign Intelligence Surveillance Act (FISA) (as written in the 70s and amended after Sept 11) was recognized. Namely, communication between two foreign entities that was routed through the US was subject to the law’s requirements for a court order. This was never the intent of the law and largely crept in due to the routing of Internet traffic through major US networking hubs
  • In addition to correcting this, the Whitehouse and the Republican congress pushed for a change to FISA that went beyond correcting the oversight and significantly extended the ability of the government to spy on citizens.
  • Congress couldn’t pass this permanently, but did pass a six month bill before the August recess, in large part because of scare tactics used by the FBI (releasing warnings of predicted attacks in DC)
  • Six months was up last week and the Whitehouse was pushing to: a) correct the known oversight, b) extend its ability to spy on US citizens without court order, and now they’ve added c) grant retro-active immunity to the telecommunications companies for illegally helping the government spy both before and after Sept 11th. And of course, if they don’t get all of this, we’ll die in our sleep, murdered by terrorists.
  • The Senate caved and gave the Whitehouse everything it asked for.
  • Surprisingly, the House didn’t and we’re now seeing extra pressure claiming that we’ll all die and it’ll be their fault. This is of course BS, but that’s the state of discourse in the country.

I don’t have much to add on the spying per se, but I will admit to being particularly offended and disturbed by the telecom immunity issue. Essentially, these companies started helping law enforcement to monitor calls, read emails, etc. well before September 11th. Their actions were not scared or patriotic, they were largely motivated by greed.

Even if this were not the case. Even if they only started cooperating after September 11th, there is no excuse for allowing extra-legal monitoring by law enforcement in violation of the 4th Amendment. While much of the monitoring may have been intended to track down terrorists, we know that tools of this nature are never used only for their intended purposes. They are always used by someone trying to get a little extra edge in a non-terrorist case or by a cop wanting to spy on a girlfriend.

Consider the following. I was the IT Security Officer for the university back in 2001. When September 11th occurred, everyone wanted to be as cooperative as possible with law enforcement within the bounds of the law. Within the bounds of the law was an important caveat. Late September of 2001, I received a phone call from an individual who identified himself as being an agent with the FBI (note, none of this is confidential – there were a few times that I was asked/instructed to sign the equivalent of an NDA; for reasons that will become obvious, this was not one).

The agent asked me for some information pertaining to an investigation on which he was working. I asked him to slow down a bit because I needed to confirm that he actually was with the FBI (and not some random caller) and then I would need a court order for the information (because, hey, I don’t want to be sued, he wasn’t asserting that this was an emergency situation, and my failure to follow reasonable procedure meant it might be me personally being sued, not the university).

The agent then starts to get very defensive and plays the terrorist card. “This person could be a terrorist, and if you don’t help me, who knows what could happen?” Taking things one step at a time, I asked for his FBI identification number. He wouldn’t give it to me. He did give me his name and a phone number I could reach him at. I called the FBI. After a couple of false starts, I was finally able to confirm his identity.

It turns out that he was sort-of an agent. Actually, he was an agent of the Bureau of Alcohol, Tobacco and Firearms (ATF). Ostensibly, he was on loan from the ATF to the FBI in order to assist them in their cases. Instead, he was working on an ATF case and trying to use his newfound FBI authority and the tragedy of September 11th to get information that he could not normally obtain. If I remember correctly, the FBI told me not to call him back and that they would handle it internally.

Granted that all of this occurred before these agencies were pulled into the Department of Homeland Security and the processes may be better. However, any time someone claims they need new powers to keep us safe from terrorists, I remember this incident and become a little more wary. If there is a demonstrated need for a new law enforcement power, then it should be discussed, weighed against civil rights and the constitution, voted on and enacted if passed. The sum total of the argument for the power should not be, “we need it or you will die!”

p.s. C&L and Mark Fiore have produced a good/amusing video illustrating this tactic.

Power companies – update

Filed under: Social — cec @ 12:19 pm

Interesting. Shortly after posting about power companies, I received a comment from Progress Energy correcting me about the plans. It seems [pure speculation here] that Progress has some sort of “blog response” team up in Maryland or northern Virginia. Anyway, I misnamed the program that I had been offered, as the comment says, it was indeed the “Balanced Bill” payment plan where you wind up spending some 11% more over the course of the year for the privilege of knowing that your bill will be 1/12th of a fixed amount. There is (apparently) a different equal payment plan which is comparable to what we had with Duke Power. However, it’s not the money maker that the Balanced Bill program is and so it is not heavily advertised. Unfortunately, I can’t seem to find details of the plan online. The closest I can get is here, which seems to be lacking in specifics.

Interestingly, the News and Observer ran an article this morning about the Balanced Bill plans and how the state might ban them. Not for the surcharge – how you want to waste money is your own business, but as I noted, they create no incentive to save energy. From the article:

“This is the kind of thing that creates a disincentive for saving electricity,” said NC WARN Director Jim Warren. “This is the old utility business model: maximum sales of electricity and talking green to the public.”

The Utilities Commission could rule on the dispute within 30 days. The commission approved the billing programs for both utilities as recently as 2004, but last year the regulators re-opened the case because of the concerns about energy waste. Critics said customers who pay a fixed bill regardless of usage have no incentive to turn out the lights, turn down the thermostat or otherwise conserve, because they pay the same price, regardless.

Those critics appear to be right. According to data from the utilities, customers who enroll in the program show a jump in electricity use that can approach 10 percent over three years.

10% in three years. Considering that the programs aren’t that old (started in 2002 and 2004 for Duke Power and Progress Energy respectively), that’s a huge increase that could potentially sustained for a longer period of time. It’s good for the power companies – after all, if you use more this year, then next year’s bill will reflect that. And if you use well beyond what they’ve budgeted for you, well, they can always cancel your participation in the plan.

Power companies

Filed under: Personal,Social — cec @ 9:08 pm

When K and I got home today, we had not one, but two different offers from the local power company (Progress Energy) to enroll in their equal payment plan program. The first was a generic flier touting the benefits of having a consistent power bill. You sign up and based on your past two years of power consumption, they compute your monthly bill and that’s what you’ll pay all year long. They’ll recompute a new amount 12 months later. We had something like that with Duke Power in Durham. They computed your recent average. You paid that for 11 months and then settled up on the 12th month, paying less or more depending on actual use.

We had liked the Duke Power plan. It equalized payments. You could track whether you were on target to have a higher or lower 12th month bill. And you only paid for what you used because in that 12th month you settled up . With that experience we looked into the Progress Energy version. That second mailer from Progress contained our actual numbers if we wanted to sign up. Unfortunately, it told us that our average monthly usage was $X and that they proposed to enroll us in the equal payment plan program at (something like) 120% of X per month. The claim of course is that if our use increases by more than 20%, we’ll be insulated from the increases of yearly fluctuations, etc. Of course, there are no refunds if you use less. So essentially, we have no incentive to conserve power and we’re likely to lose money. Wow, where can I sign!

Of course, it’s not all shiny green conservation at Duke power either. I was flipping through the N&O today and ran across an interesting Point-of-View letter from Jim Rogers (president and CEO of Duke Power). The POV letter was promoting their Save-a-Watt program as a cheaper, better alternative to renewable power sources – a program to promote power conservation. If you read the letter, you should quickly note that it’s missing one thing: details on the actual program.

Fortunately, the details aren’t hard to dig up. The proposed program would add $15 per year to every customer’s power bill. This fee would be used to promote energy conservation and provide discounts on energy efficient appliances. Interesting. It does have the down side that those too poor to afford new appliances are subsidizing those who can afford it, but I’ve heard of worse ideas. That said, it seems a bit counter intuitive that a power company would want to cut into their profits by encouraging conservation. Silly me. I haven’t described the other half of the plan. The company would then take the projected conservation amounts and would increase rates to cover 90% of what it would have cost to produce the amount of conserved energy. Their claim is that consumers are now saving 10%! Everyone’s happy, we don’t have to produce power from renewable sources and we can still claim that we are green!

Huh?!

It’s a shell game. It’s the old riddle of “where’s the missing dollar?” It only sounds reasonable if someone’s throwing out numbers fast enough that you don’t add up what they mean.

What Duke Power is proposing to do is to make a projection for energy consumption over the next N years without the program. Essentially, it’s a table that says in each year, the area will consume so much energy. Then each year thereafter, they look at how much energy was actually used. For every kilowatt-hour that isn’t used, their rates will increase so that they earn 90% of that missing kilowatt-hour. Save 100 kwhs – pay Duke Power for 90 kwhs.

Hrm, perhaps a more specific example is in order. Let’s assume that I run a small power company for my house. K is currently using 1 kw of power I produced through a RAIHW: redundant array of inexpensive hamster wheels. To produce my 1 kw of power, I’ve got 100 hamster wheels connected in a serial and parallel configuration. Assume that each hamster costs me $10 plus another $5 for food each year. So my infrastructure costs are $1000 in hamsters, plus another $500 in food each year. If we used 1 kw in 2007, I’m going to predict 10% year over year growth: 1.1 kw in 2008, 1.21 kw in 2009, 1.33 kw in 2010, etc.

Assume that on top of the amortized infrastructure costs plus the operational costs plus profit (call it $800 per year), I charge K a $10 fee (I’ll use the money to encourage her to change out an incandescent for a florescent bulb). According to my projections, I need to increase capacity by 10% in 2008 – or 10 new hamsters. Assuming the infrastructure costs are amortized, we might expect our power costs to go up 10% ($80) to $880 per year.

But what if my projections are wrong? K only uses 1 kw in 2008. Well, as a producer, I’m happy. I don’t have to buy 10 new hamsters (saving $100) and I don’t have to feed any new hamsters (saving $50). But wait! I’m missing out. I’m not getting the profit on that 0.1 kw of power. Under the Duke plan, I’ll still get 90% of that money. Even though I have no additional expenses, K’s power bill will be $872 per year. I get $72 free and clear; and K “saves” $8 per year because without my charging a $10 fee, she never would have replaced that incandescent bulb, so she would have used 1.1 kw. See, we’re conserving hamsters, K’s power bills increased less than I projected they would have, even though she used no more power. Everyone should be happy.

Duke Power claims that this is their incentive to increase conservation through education and programs to help purchase more energy efficient appliances. Of course, it’s also an incentive to game the system and make unreasonably large growth projections. Even if you assume that doesn’t happen, it’s a great deal for Duke Power. The program is funded by a fee. You earn enormous profit margins off of energy that you aren’t producing. You get to claim that you are a supporter of energy conservation. And you get to tell the environmentalists that want you to build renewable (or in some cases nuclear) power plants to go to hell, while building CO2-intensive coal fired plants when needed.

What’s not to love?

CO2 emissions and compact fluorescent bulbs (updated)

Filed under: Social,Technical — cec @ 2:37 pm

There’s something about the idea of global warming that seems to drive people of a certain mindset completely insane. You start seeing things like: “the planet’s not warming up!” “Okay, maybe it is warming, but humans couldn’t possibly be causing it.” “Fine. We are causing global warming, but we can’t do anything about it.” “What, we can? Well it’ll destroy our economy.” “You mean it won’t? Well, you must be French.”

And then you get guy’s like Andrew Longman whose argument runs something like, “I don’t believe in global warming, but you do. And congress’s ban on incandescent bulbs is going to put out more CO2 which in your mind means we’re baking the planet. Stupid liberals.” Then, after derisively stating that liberals are not hard headed quantitative types, proceeds to lay out an argument that is so stupid, a 12th grade physics class could take it apart.

Unfortunately, a 12th grade physics class isn’t here right now, so we’ll have to do it ourself.

Longman’s argument is that incandescent bulbs replace some portion of the normal heating used in a house. An NPR story told him that electric heat is more efficient than burning natural gas – in terms of CO2 emissions per unit of heat, therefore, by converting to CF bulbs we are using less electricity to heat our homes and more natural gas therefore, we are putting out more CO2 than if we used the original incandescents. He then proceeds to describe liberals as soft headed and laughs that their silly utopian dreams are undone by lack of an engineering mindset.

That’s a challenge that’s hard to resist. So let’s take this apart. First, Longman doesn’t realize that he’s comparing three different kinds of heating. He’s simplified to two: gas and electric. But let’s be quantitative and list all three:

  1. natural gas heaters
  2. electric resistive heaters
  3. heat pumps

Natural gas heaters burn natural gas, heating air that is then circulated around the house. Pretty simple idea. Relatively efficient.

Of course, very few people heat their homes with electric resistive heaters. This is the “emergency” or “auxiliary” heat setting on your heat pump. You run electricity through something resistive and generate heat. It’s a one to one conversion of heat for electricy. Every watt you put in, you get one watt of heat out. Run it for a length of time, and you can covert to watt-hours or BTUs. Now wait, I mentioned that you get electric resistive heaters by running electricity through a resistor – that’s a light bulb! Okay, we now know that light bulbs are electric resistive.

It’s very expensive to use electric resistive heat. So most people using electric heat use a heat pump. Think reverse air conditioner – you air condition the outside in winter extracting the heat and putting it into the house. A given heat pump, operating at a given temperature differential will have a specific coefficient of performance (CoP). Essentially, how much electricity does it take to extract a given amount of heat. Depending on circumstances, that CoP may be between 2 and 5. In other words, it takes 1 watt of electricity to extract between 2 and 5 watts of heat from the outdoors and move it inside. Hrm, now we’re starting to see how NPR got its numbers for pounds of CO2 created heating a house with electric vs natural gas.

But of course, Longman has challenged us to be quantitative and so we must preserve persevere. Let’s look at his example. Assume you have a house that contains 30, 100 watt bulbs that are always burning. In his example, a conversion to 20 watt compact fluorescents would mean that instead of getting 3000 watts of heat from the bulbs, you now get only 600 watts of heat from the bulbs and have to burn the equivalent of 2400 watts worth of natural gas. Using his soft, fuzzy, NPR numbers (that he’s misunderstood), Longman says that you emit less CO2 with the incandescents.

But he hasn’t really shown that. So let’s do the math. Basic numbers we’ll need:

  • CO2 emissions per unit of heat from natural gas
  • CO2 emissions per watt-hour of electricity
  • watt-hours consumed using our 30, 100 watt bulbs over a period of time

According to the Natural Gas Association, 1 billion (1,000,000,000) BTUs of heat from natural gas produces 117,000 pounds of CO2.

According to the Department of Energy, we produced 1.341 pounds of CO2 per kilowatt hour of energy generated in 2000. (Note, this is generated, some power is lost in transmission, so this is an upper lower bound for [CO2 generated by] power energy used in a home).

Now we’re getting somewhere. So 30 bulbs at 100 watts each, use 3000 watts of power or 72 kilowatt hours per day. That works out to 96.552 pounds of CO2 per day for heating your home with light bulbs.

What about natural gas? Well, we don’t have a CO2 pounds per kwh for natural gas, but since the CoP of a light bulb is 1.0, we have a conversion from electricity to heat. Our 72 kwh of electricity converted directly to heat turns out to be 245800 BTUs. Which turns out to generate 28.7586 pounds of CO2 if produced by natural gas. Of course, we haven’t replaced100% of our light bulb heat by switching to CF bulbs, only 80%. The other 20% is still [comparable to] electric resistive. So if we take 80% of 28.7586 and add 20% of 96.552, we get 42.311 pounds of CO2 generated by using 30, 20 watt CF bulbs.

Now, unless I’ve forgotten my basic math, 42.311 pounds is less than half of 96.552 pounds. So, I think that means that Longman was full of crap and is apparently a fuzzy headed conservative and not really a quantitative man at all.

Q.E.D.

Updated:

Oh, so I forgot to look at summer when we’re trying to cool the house. Turns out that the difference is even greater. In the summer, all of the heat is waste heat – we don’t want it and we need to get it outside. Assuming we’ve got a high efficiency air conditioner, it takes about one watt-hour of power to remove five watts-hours of heat, i.e., let’s assume a CoP of 5.

In the summer, running Longman’s 30, 100 watt bulbs 24 hours a day still takes 72 kwh per day plus we’ll need to run the a/c for another 14.4 kwh per day. That gives us a total of 86.4 kwh creating at least 115.824 pounds of CO2.

If we assume that all of those bulbs are now 20 watt compact fluorescents, then we require 14.4 kwh for light, plus another 2.88 kwh for cooling. Total of 17.28 kwh per day for lighting and cooling the lighting. Those 17.28 kwh will create… 23.17 pounds of CO2. Or not surprisingly, one fifth the CO2, since the bulbs use one fifth the electricity.

Of course, not everyone is going to use 30, 100 watt bulbs for lighting 24/7, but the relative proportions stay the same.

K wins!

Filed under: Personal,Social — cec @ 9:56 pm

Okay, slight confession time.  I’m something of a closet political junkie.  Not so much the “who’s up, who’s down” campaigning politics, but the questions of policy, who supports what, what makes sense kind of thing.  If I were involved in politics directly, I suppose that would make me a wonk, not a hack.

Anyway, K and I were having a discussion last week about the presidential primaries.  K’s position was that if Huckabee wins the GOP primaries, we’re all in serious danger because the man holds positions that are bad for women, minorities, basically everyone that’s not a middle class white heterosexual male.  I, on the other hand, maintained the position that a Huckabee win in the primaries would be hysterical.  🙂

To a large extent, our positions were based on different contexts.  K is concerned that the republican would win the general election since, hey, it’s been a while since they haven’t – no matter how bad their candidates and policies are.  I was thinking “hysterical” since it would break wide open the GOP coalition of money, guns and religio and I have a hard time picturing any republican winning this time, since they are all so awful.

So, that said, I think K wins this one based on this short article:

“[Some of my opponents] do not want to change the Constitution, but I believe it’s a lot easier to change the constitution than it would be to change the word of the living God, and that’s what we need to do is to amend the Constitution so it’s in God’s standards rather than try to change God’s standards,” Huckabee said, referring to the need for a constitutional human life amendment and an amendment defining marriage as between a man and a woman

I’m more than a little terrified that a presidential candidate would talk about amending the Constitution in order to suite his own religious beliefs.  Where do you even start with this?  This country was established to intentionally and explicitly keep religion from controlling the government.  While the phrase “separation of church and state” is not in the constitution, the concept is one of the founding principles of the constitution as a whole and of the first amendment in particular.  The founders saw first hand the damage that could be done when a particular religion dictated to the government.  This is why the establishment of religion was explicitly forbidden.

Beyond the 200+ years of tradition, beyond the very heart of our government, there’s the whole other issue of which “word of the living God” to you plan to establish? There are over a dozen major religions represented in this country.  Even within the largest, there are literally hundreds of Christian denominations (side note, why are splits among Christian beliefs called denominations and those of non-Christian beliefs called sects?) each of which has there own special interpretation of the god’s word.

Perhaps Huckabee was just pandering to republican christians, many of whom can be counted on to support certain positions.  But to make the claim that these republicans speak for all christians, let alone for god or all religions is crazy.

So, yes – K wins: Huckabee winning the GOP primary would not be hysterical, it would in fact be scary.

I call BS

Filed under: Social — cec @ 9:58 am

I missed on Sunday, but under the theory of better late than never…

Donald Kerr is the principal deputy director of national intelligence, so presumably he speaks with some authority regarding the government’s view of privacy. In a recent Associated Press article he made several remarks which I find exceedingly scary, misleading or both. First up:

Privacy no longer can mean anonymity, says Donald Kerr, the principal deputy director of national intelligence. Instead, it should mean that government and businesses properly safeguard people’s private communications and financial information.

So if I understand this, privacy, whose definition traditionally includes anonymity and the control over personal information, should now be defined to exclude both. Instead we should trust the government to safeguard the formerly private information. Correct me if I’m wrong, but we have a word for the protection of sensitive information – it’s called confidentiality. What Kerr is saying is that there is no such thing as privacy when it comes to government, all you really can hope for is confidentiality.

I’m not certain it’s possible to express how abhorrent to the constitution the attitude conveyed in that statement really is. Kerr is essentially saying that there is no longer a fourth amendment providing against unreasonable search and seizure.

But wait, there’s more! Now for a limited time, in addition to an anti-constitutional perspective on government, Kerr gives us a bunch of crap to justify it:

Kerr said at an October intelligence conference in San Antonio that he finds concerns that the government may be listening in odd when people are “perfectly willing for a green-card holder at an (Internet service provider) who may or may have not have been an illegal entrant to the United States to handle their data.”

First, let’s get rid of the fear-mongering. Is Kerr suggesting that the U.S. government is giving green-cards to illegal immigrants? That seems exceedingly unlikely. Second, I’m fairly certain that a green-card holder is not going to be able to arrest me in the event that he or she a) monitors my internet traffic, and b) thinks something is a concern. Third, remember that privacy is about the control of personal information. It’s about having the ability to decide who gets to see what information. Having a government monitor all of the information from all ISPs completely strips away privacy. As to the ISP itself, I think that most of us are used to thinking of them as common carriers (like the telephone companies they are descended from). Their status as common carriers suggests that they are not monitoring all traffic. Moreover, there are laws that prevent them from turning over information to the government without having a court order. Of course, these are the same laws that the administration is pushing congress to overturn through retroactive immunity to the telecom companies.

Finally, we have this:

Millions of people in this country — particularly young people — already have surrendered anonymity to social networking sites such as MySpace and Facebook, and to Internet commerce. These sites reveal to the public, government and corporations what was once closely guarded information, like personal statistics and credit card numbers.

“Those two generations younger than we are have a very different idea of what is essential privacy, what they would wish to protect about their lives and affairs. And so, it’s not for us to inflict one size fits all,” said Kerr, 68. “Protecting anonymity isn’t a fight that can be won. Anyone that’s typed in their name on Google understands that.”

Again, another lovely distortion. Kerr is suggesting that the intentional, willing dissemination of information is comparable to the government hoovering all of your communications off of the internet. This is complete and utter crap. Are there things about me on the internet? Of course. There are the public records from Durham and Chatham counties and bunch of emails that I sent to public mailing lists. Oh, and the information that I’ve purposefully posted. With the exception of the public records, all of this is information that I made public. Comparing this to the government monitoring all of my personal communications that I have not chosen to make public is an intentional distortion of the basic concepts of privacy. But then I guess we knew that from the beginning of the article.
