Hazy Skies in Hong Kong? Just Pose With a Fake Skyline

Hong Kong’s skyline, featuring dozens of brightly-lit high-rises wrapping around Victoria Harbor, is justifiably famous, and one of the main draws in the city’s $37 billion tourism industry. Unfortunately, Hong Kong’s recent urban haze is more than just a health hazard: It also ruins perfectly decent photo opportunities.
So in an inspired attempt to placate disappointed tourists, large, blue-sky banners of the skyline have appeared along the city’s harbor-front walkway. For these tourists, it’s a perfect solution — so long as the actual, gray sky doesn’t creep into the shot.

Supply-Sided Environmentalism

Tax Cuts: a Virtuous Cycle

One of the most appealing things about supply-sided economics is that its proponents describe a feedback loop that transforms taxcuts, which are commonly thought of as “costing money”, into a source of new revenue (when measured through a larger economic base).

Energy Efficiency: a Virtuous Cycle

Though their isn’t anything “supply”-based about some environmentalist’s proposals for increased energy efficiency, is see an interesting parallel.

Increased Energy efficiency is normally thought of as an increasing cost to get a reduced benefit. Think of home insulation and improved windows.

Improved windows and more insulation cost more money; and as the desired energy savings increases, the cost increases, so as to be of diminishing value.

Like the supply siders, Amory Lovins looks for circumstances in which evaluations of individual actions within the traditional model don’t hold true for their effect on the system as a whole.

If Lovins were building a home, he would measure the future savings from the improved insulation and windows, but he would not stop there. Instead, he would analyze the effect of those savings on other parts of the

Would the improved insulation and windows allow him to buy a smaller furnace and air conditioning unit? If so, he could take the savings from the air conditioning unit and furnace and plow it back into even better windows and insulation. Perhaps he would spend the money on more design, so that the south side of
the house would take better advantage of passive heating principles. Lovins would continue to iterate through this process, continually looking to pass on savings to other parts of the system.

Tunneling Through the Costs

Lovins describes his technique as “tunneling through the costs”, where he takes a graph for which cost-effectiveness has seemly been maximized, and demonstrates that higher energy saving can be advanced by eliminating one of the system’s assumptions, such as reducing or eliminating the heating or cooling system.

The New York Times ran a story recently about Passive Solar Houses in Germany in which the the need for a
furnace had been reduced or eliminated, freeing up money to be put to alternate uses.

Time magazine recently ran a cover story titled “America’s Untapped Energy Resource: Boosting Efficiency“.

It seems that the concept of reducing costs by optimizing an entire system would be attractive to many people; and unlike supply-sided economics, its effectiveness should be testable on the small scale.


For those who have an unfavorable view of “supply-sided” economics, I’m not trying to disparage Amory Lovin’s approach. The actual benefit of taxcuts can be debated. Rather, I think it would be interesting for those who like the idea of supply sided economics to consider the practicality of “Tunneling through” barriers to efficiency.
