- # > --------------------------
- #
- # This is fine essay, well documented, logical, etc., but I am left with a
- # question -
- # Are you favoring government mandated efficiency?
-
- Yes to provide a bottom line on energy efficiency. In the essay I was
- mainly trying to show that there was a large potential for energy
- efficiency, and that it was a cost effective means of CO2 abatement. I don't
- believe that mandated efficiency is the only tool that should be used. Also
- it should be introduced gradually. As an example, in Sweden way back in the
- early decades of this century, they decided to increase the insulation
- standards of their housing. The introduced guidelines which stipulated
- standards only marginally above the norm at the time. Gradually they
- increased these standards over the years, taking note of any economic
- effects. The result: Now Swedish building standards mandate house that use
- as little as one fifth of those that British standards require. The idea is
- that any efficiency standards should be phased in, starting with some that
- only marginally improve on the norm.
-
- # That's an important question, because it leaves people without choice.
-
- True, but in many cases, one finds that unlike light bulbs, there is little
- correlation between energy usage and price of an electrical appliance. In
- the study done for the Swedish State Power Board mntioned in my essay
- there's a graph of the price of fridges against their electricity
- usage. It looked like random dots over a square area. The most efficient
- models were as often cheaper than others, as they were more expensive. In
- this market at least, it wouldn't force people to buy more expensive
- machines.
- # But without it, people often choose lower efficiency options. Even if they
- # cost more, just for reasons of "style" or "sexy". As I've pointed out
- before,
- # this must be considered. I tend to be be worried about government
- mandating
- # on choice or another. I have no problem with carrot-and-stick approaches
- # to encouraging certaina choices (subsidy if you do, tax if you don't),
- # especially if it can be demonstrated that both the subsidy benefits
- # those paying the tax on the other end. The experience with cars is a case
- # in point. Few people really want to buy a Geo Metro. They'd rather
- # get sports car, even though it costs more and is much less efficient.
- # They have good reasons and not so good readons for their choice. How
- # about hair dryers? Big energy user, but does anyone really need one?
- # I never use one, and so I don't have hair like Tom Brokaw or Bill Clinton,
- # but my hair is clean and neat and only takes about 20 minutes to dry all by
- # itself. I have met very few other people who don't use them. I haven't
- # used a clothes dryer in 2 years - it can be inconvenient, and it certainly
- # involves a lifestyle change, but then I pay nothing for a dryer, and
- # nothing for the power, and that's the ultimate in energy efficiency.
- # But how many people do you know who do that? I have never used a
- dishwasher
- # in my life. The list goes on. Although all these options would require
- # people to change how they live, few really cost any time. People choose
- # to use these appliances for other reasons, not really convenience and
- certainly
- # they aren't thinking about energy when they make the decision.
-
- Firstly, I did try to demonstrate that it was through using more energy
- efficient designs rather than change of lifestyles that much of the savings
- could be achieved(Don't get me wrong, I do feel that we should think more
- carefully about some of the more trivial uses we have for energy). I think
- minimum efficiency standards though are in the consumer's interest, in that
- they will pay less money on running the appliance. There are some cases
- where this won't balance the extra cost of the energy efficient model, and
- here more thought would be needed before such measures are taken.
-
- # This is a hard problem. I don't want to prohibit choices. But I would
- # like to encourage good choices through appropriate taxes or whatever.
- #
- # But I doubt that taxes and subsidies could accomplish the large goals
- # you have in this area.
-
- I don't know about that. If by law all products in addition to meeting
- certain efficiency requirements had to display their energy requirements
- clearly, and tax exemptions were given for particularly efficient models, I
- feel that this could have quite an effect. In the area of electrical supply,
- utilities could be mandated to use least cost planning(as many do now in the
- US) and here it can often be cheaper to give away free energy efficient
- light bulbs than to build a new power plant, or even operate an existing one
- for longer or with higher output. I'll try to give some evidence on the
- performance of energy efficiency so far later, but I recommend you read some
- of Amory Lovins's work in this area, he seems to know what he's on about.
