But, nonetheless, it's one which many countries have adopted, with considerable success. It both gives people an incentive to give up smoking and simultaneously punishes those who choose to continue, despite knowing the issues involved in doing so.

I agree they take up more bulk on the road, but given the separations needed between cars, the size difference is less ("only a fool breaks the two second rule" as I was taught). Or develop into them ability to drive closer more safely (e.g. chaining of breaking, etc.). The whole point is that it's a challenge.... As an aside, does the US have something like the European Union Enery Label? |

@steve Bigger cars are already taxed more due to the increased wear and tear on infrastructure.

Harry, I was born in a top 10 target during Mutually Assured Destruction. I came of age in the OPEC/We're running out of resources/Survivalist era. I listened to the Nuclear Winter arguments (Solve global warming by a few clean nukes in the Sahara? Hmm...). Nowadays, it's the world is coming to an end due to Global Warming. Sorry, I've heard endless tales of catastrophy "if we didn't do something" (usually couched as some version of give up your freedom/lifestyle/future for somebody else's fears). Well, we "didn't do something" over and over and the world didn't come to an end. It just got more affluent. I'm sorry, but I'm not buying catastrophy now. Maybe the wolf is really coming, but I'm not even certain about that. And certainly not going to give up my lifestyle for other people's fears. |

Even though I live on the West Coast, I don't think the rise of the Ocean will effect me directly. However GW folks claim that Katrina damage is caused by GW, what more warning do people need?
How about the rash of Volcanic eruptions? That would be very hard to prove that they are caused by GW. And if they proved it would anyone take more specific action? Yes non-scientific people will tend to ignore Scientist (though they did heed the warning of the thining of the Ozone layer). I suppose Scientist should ignore those non-scientific people or think of new ways to brainwash them. ------------------------------------ Disclaimer: I install bathroom lights with dimmers (many people can't stand the CFL at night because they are too bright). I ride an electric scooter and don't drive IC cars. I am not a writer but more of a reader/commenter. |

With those concepts in mind, here's the questions that lead to the economic argument:
If I estimate the life of such a bulb at 1000 hours usage (arbitrary, probably too high, but typical of the bulbs I might buy to replace it now), we see that it will consume 100KWh over its entire service life. That's about $10 worth of electricity (in back-of-the-envelope numbers). Now, even though I estimate that it is likely to be more than 40 years old, let's use the 20 years I've lived in the house as a baseline (that is, we're assuming it burns out this evening after a total lifespan of 20 years). We'll also assume that the use of electricity (and the price of electricity!) is evenly spread across the entire period -- 50 cents of electricity each year. Note that this set of assumptions boils down to using the attic light for 50 hours per year; in reality I probably haven't used it as much as 50 hours over the entire 20 years we've been in the house! But never mind, we'll run with it. More facts: a comparable CFL costs $5 at my local big-box store (actually a bit less, but we're using round numbers to make the calculations easy), and consumes 28W for the same light output. We'll call that 25W for simplicity. A new 100W incandescent costs $1 (actually rather less, but... round numbers!)First we'll calculate the payback period for a CFL in the attic (Q1 above): So if I install a CFL in the attic I spend $5 today, and gain back $0.375 each year into the future. If I install another 100W incandescent, I spend $1 today and gain back nothing each year. Without considering the time value of money, the payback period for putting a CFL in my attic is... Ten years eight months. Normal financial estimation says that (low-risk) investment paybacks under 3 years are "no-brainers." Jump on the opportunity right away. Paybacks under 7 or 8 years are worth investigating; paybacks over 8 years are questionable. Remember, this is BotE estimation for simple stuff, not questions of "corporate strategy" or long-term R&D. Simple stuff, like light-bulbs and insulation, and vehicle purchases. If we estimate the time value of money using a 3% deflator, we would say that this years savings is worth $0.375 today, next year's saving is worth $0.36, and the final (10th) year's savings is worth $0.28. This adds another couple of years to the payback period. BotE says not to put a CFL in the attic... at this time! Now let's look at Q2: Is there some other bulb in the house I might replace with a CFL instead of the attic bulb? Answer: Sure. I have some closets whose lights are used substantially more than the attic light. I probably replace their bulbs every 3rd or 4th year. Assuming, once again, 1000-hour 100W bulbs (for simplicity) and the same costs as above, I'm looking at $10 in electricity spread over 3 or 4 years. Using 4 years as the number, BotE says that payback period is right around 2 years. Time to replace those bulbs, even if they haven't burned out yet! (Good thing I already did...) Now for Q3: Even assuming it costs $0.50 per year, that attic bulb is insignificant in my total electricity usage picture. If I want to invest $5 ($4, really due to the up-front price-difference in bulb cost) in reduced usage, I should put the money where it will make a larger difference. Specifically, that attic bulb is certainly the very last one that I should consider replacing. Every other light in the house sees substantially more use. Before spending extra money replacing that particular bulb, I should first spend money on:
So, what I believe I have shown above is that efficient lights aren't the right solution for rarely used fixtures, unless and until all the higher-benefit/shorter-pay-back problems are addressed first. To connect back to the original discussion: Don't legislate lower efficiency things out of existence! Instead, educate people about the choices they are making. You'd be surprised what response you get when you point out that folks are unthinkingly leaving money on the table (or worse, sending it to "the big bad utility company!") when they could have used it for something they wanted more but couldn't afford. I submit that Steve's propose Onuissance is better served through education than legislation in cases like this. Xenophon Last edited by Xenophon; 04-09-2009 at 12:54 PM. |

Vehicle emissions are an entirely different story. People who cough in your face, use the restroom without washing their hands afterwards, and have a miriad of other bad personal habits (that are often unseen/unknown to me) are of a greater danger to me and my welfare than any smoker. People who drink alcohol are a greater threat to my welfare, especially if I can't avoid them or the danger they can be to me unless I see a drink in their hand. As long as smoking is legal, I see no cause to punish smokers any more than we should punish anyone for doing anything that is perfectly legal, and wihin their rights to do, no matter how repulsive it might be to us personally. |

Electrical power was deregulated in Texas several years ago and you can purchase it from one of several different providers. Of course, the electricity to your home comes from the same grid as everyone else but the point is that you pay your provider to ensure that an equivalent amount of power that you use gets put onto the grid. I pay for a plan which is "100% wind" which costs a mere 3.3% more than the most common provider (which comes mostly from coal and natural gas plants). That's almost no difference at all (less than $10 per month for me) and yet there are very few subscribers here who use it. I would love to see the majority of the people here sign up for it. We might be able to shut down some coal plants that way. But the bottom line is that no one cares. Or they don't know enough to care.

Similar deals are available here in PA. Sadly, no-one offers an "all nuclear" option.

![]() Like a more-frequently-used light-bulb. Or a more-efficient fridge or A/C, or any of a zillion other things. And because the list of things to improve is so long that I can't do them all, this is a case involving substitution, not addition. So, am I more responsible if I fix the trivial (but low-priority) thing first? Or am I more responsible if I fix something with faster payback first? Note: I'm not suggesting that the lightbulb should be incandescent forever! I'm asking "where should I start?" I presume that you agree that I should fix the high-pay-off things first. We can argue later about whether that payoff is in terms of $ or carbon or air-pollution... but when we're talking about electricity (and reducing usage thereof), KWh per month (or year, or whatever) work just fine as a proxy for any of those benefits. I argue that the responsible choice is to upgrade that rarely used bulb only when either (a) the cost difference drops to $1 or so (raising its priority on the list), or (b) I've already made as many of the higher-priority changes as possible. And no sooner. The issue here isn't whether or not to reduce usage. It's "how to decide where to deploy time/effort/money etc., given that we don't have enough time/effort/money to fix all the problems right now." And that sort of question is routinely answered by businessmen, economists, engineers, etc. And it's best approached in much the fashion I laid out above. Are we on the same page in terms of this message? Xenophon P.S. I realize that I dumped a screenful of text at you. It's written at that length to expose all the reasoning. But BotE-wise, that's a 30-second calculation. |

I rather expect that Ralph Sir Edward will look at my analysis and say:
There's a bunch of low-hanging fruit that are "no-regrets"-style changes. Of course we should all make those, it's just common sense. For example, if your refrigerator is more than 10 years old, it's probably* financially sensible to buy a newer, more efficient model -- even if you need to take out a loan to do so!Xenophon *A very few of the most efficient models from 10 years ago might not make sense to replace. Replacing any other refrigerator of that vintage pays off in 4 years or less. That's a "no regrets" change. You win, whether global warming is a problem or not. There're plenty more items like that out there. Spread the word! |
