Do compact fluorescent lights really save energy?

Earlier this month, Congress passed a law which will essentially force the public to switch to compact fluorescent lights. (CFLs)  Environmentalists and light bulb makers joined forces to boost power and profits, and perhaps sue the competition out of existence.Some people object to the narrow light spectrum and toxic Mercury content of CFL lights, but I don’t care about those things.  I have replaced most of the incandescent lights in my apartment, and plan to eventually replace the rest.  What I question is not the usefulness of CFLs, but the premise that switching to them will “save energy.”

As with most goods and services, the price of a utility influences the quantity I am willing to pay for.  When the price of gas doubles, I reconsider taking road trips, and try to be more efficient with my driving.  Likewise, when the price of electricity falls, I am more liberal with my power consumption.   Compact fluorescent lights lower the cost of lightning in two ways: they use one quarter of the energy, and they last ten times as long.  These innovations encourage greater usage of lighting.

I have a spiffy IKEA lamp behind my couch, but because I don’t have a light in my ceiling fan, it needs to be extra bright.  Furthermore, the geometry of my living room makes it annoying to walk behind the couch every day to turn it on.  By switching to a compact fluorescent light, I was able to get a 100 watt equivalent light in a 60 watt socket, and thanks to its efficiency and long life, I just leave the light permanently on.  I am enjoying greater convenience, but I don’t know if I am saving any energy.

If the average consumer’s monthly lightning budget is fixed, they might compensate for the higher efficiency and lifespan of CFLs by increasing their lightning usage to completely offset any energy reduction.  This would be especially true if consumers are forced to switch to CFLs by legislators rather than a desire to save energy costs.  Much as auto safety regulations can lead to reckless behavior, forcing consumers to switch to more efficient lights might actually increase their energy usage.

Allowing restaurants to make money off hungry people is wrong

Statism doesn’t sound as great when it comes to other fields, does it?

Mayor Thomas M. Menino embarked on a highly public campaign yesterday to block CVS Corp. and other retailers from opening medical clinics inside their stores… “Limited service medical clinics run by merchants in for-profit corporations will seriously compromise quality of care and hygiene. Allowing retailers to make money off of sick people is wrong.”

Proof most Americans are uneducated

At least when it comes to biology.

Update: there’s a discussion of this post on ObjectivismOnline.

Is plastic flotsam good for the environment?

The latest environmental “crisis” is the floating garbage polluting the world’s oceans, which is said to be killing “more than a million seabirds and 100,000 mammals and sea turtles each year.” But does this number really mean anything? The number of animals killed alone is meaningless without context. Understanding why requires a little ecological intuition.

Suppose that a hunter goes into an isolated forest once a month to kill a deer. What is the hunter’s impact on the deer population? In the short term, after each deer is killed, the population decreases by one deer. In the long term however, the forest is only capable of sustaining a fixed number of grazing animals, and each deer that dies makes room for additional animals. Each dead adult means that there is more food available for the next generation. Whether the deer population remains stable or decreases depends on the adaptive capacity of the species to reproduce fast enough to compensate for the missing deer. If only a small percentage of the population is killed each year, then there will probably not be any change in the population.

Given that there are colonies of sea birds which number over a million and a single sea turtle lays 150-200 eggs, it is far from obvious whether the number of animals killed by garbage has any impact on their population. Animals that survive due to decreased competition may balance the animals killed by plastics. Furthermore, the more drastic the impact on animal populations, the higher the evolutionary pressure for the surviving animals to adapt to their new plastic-rich environment.

It is conceivable that plastic waste has a beneficial impact on the oceans, as it is well known for attracting schools of fish, perhaps because it forms a base for microorganisms. It certainly wouldn’t be the first time that environmentalists were dramatically wrong about the impact of a deadly pollutant. In any case, the evolutionary process will certainly maximize the potential of marine species to take advantage of their new environment.
