Ethanol and Absurdity

One doesn't expect creative policy from a Bush Administration that gave us the Iraq War and the military "surge." But the President's energy proposals, made last night in the State of the Union speech, have reached a new creative low. After all the hoopla about initiatives, his actual proposals were simply recycled nostrums that he has proposed before—albeit with minor differences. Last January we were exhorted to reduce our dependence on foreign oil by switching to more economical vehicles and biofuels. This year we are supposed to reduce our gasoline consumption by twenty percent over the next ten years. We will do this by switching to more economical vehicles and biofuels. This time the government will help by making fuel economy requirements a bit more stringent. And it will itself move toward more economical vehicles and biofuels.

Proposals that made little sense last January make even less sense this year. Even on their face they are inadequate. If we merely cut our gasoline consumption by twenty percent over the next ten years, this will not make us energy-independent because there is not enough oil in U.S. territory to supply what we will still be using. Conservation at this level would barely make a dent in our dependence on foreign oil. And a twenty-percent cut in gasoline consumption will do virtually nothing about climate change. For that, the cuts must be far more stringent, and they must include all fossil fuel usage, not just gasoline usage. Mr. Bush's conservation proposal would make us feel as if we were achieving real economies without actually requiring us to do anything meaningful.

Even the ethanol numbers don't add up. The boom in ethanol is good for corn growers and possibly for the American waistline because corn refined into fuel will not be refined into fructose and added to the food supply. But even a mainstream economist like Robert J. Samuelson argues that we just cannot grow enough biological material—corn, switchgrass, wood chips (wood chips?), whatever—to feed our cars.

I emphasize wood chips above because plans to use them reveal the absurdity of plans for a mass switch to ethanol. At the moment, most wood chips used for biofuels are sawmill waste that we would generate anyway and are recycling. But if we switch to ethanol on a large scale, we may find ourselves needing additional sources of wood chips. As we have done with corn, we may be tempted to create wood to use as chips for fuel.

We can't, of course, create wood. Unlike money, wood chips grow on trees. They don't just appear magically out of nowhere. Trees, even those planted for harvest like Christmas trees, take time to grow. Big old trees, the most abundant source for wood chips, take years, sometimes hundreds of years, to grow. How far will be be prepared to go just to keep our cars running? Are we to strip our old-growth forests just so we can continue to drive everywhere? Substitute trees for food crops so we can do our banking from our cars? And how will cutting down trees to fuel our cars help to reduce global warming?

The answer to the last question is simple: It won't. Using trees to fuel our cars can only increase deforestation. That is a step toward, not away from, global warming.

This is not policymaking at all. It is, like the military surge, an attempt to distract us from the real problem, which in this case is our dependence, not on foreign oil, but on the private car. No one ever got elected by telling the people that they should take the bus or the train—or walk. But somebody must begin to do so. Obviously, Mr. Bush is not that person.

Brief Note: Sustainable South Bronx

To rebuild for the future, we have to start somewhere. An individual can change his or her behavior, and that is all to the good. But individuals by themselves can change little without organizing—to pressure policymakers, to stop ill-considered and harmful developments, and most important, to change our institutions in a positive way.

In cities, the best vehicle for organizing is the neighborhood. People in the neighborhood know each other, they share a common interest in the welfare of the community, and if something is wrong with the environment in their area, they can sometimes literally smell it.

That was the case a few years ago in the South Bronx. It is less so now, thanks to one of the most exciting grassroots environmental efforts in the country: Sustainable South Bronx. Founded by Majora Carter, who grew up in South Bronx when it was, quite literally, New York's dumping ground, this organization has helped reverse the decline of the neighborhood and created hope where before there was the smell of rotting industrial waste. It is a group that more than repays study and a model for similar groups everywhere.

Christmas Letter 2006

The curious thing about the future is this: Although it has not yet happened, it affects the present in ways we may not even recognize. We plan for it, and in doing so we make decisions about our families, our work, and what we value most in life. By our choices—even by not choosing, which is itself a choice—we create it for good or ill.

So it is now. We face a future of limits because the world is finite. We face a future of climate change that will also constrain us. Our future will be unlike that of any other generation.

For many of us, this is a frightening prospect. It calls into question all our past values, from economic growth to trips to the local shopping mall. How will we live in the uncertain world that is ahead?

There is no easy or sure answer. The only way for us to move forward is to have faith. Not faith that certain creeds are true. Faith is not a way of proving propositions. It is the act of trusting in ourselves, in others, and in the future, even though we cannot be certain of the outcome.

We can move forward only if we trust that, by doing what we can to create a better future, we will make a difference—even if at this moment we cannot see a clear path ahead. Like Frodo in The Lord of the Rings, we must take the Ring, trusting that we will somehow find the way.

Without this kind of trust, we will see no path at all. With it, we can make a beginning. And we can move toward a more hopeful future.

Design for What? Third of Three Parts

A ten-story parking garage at 15th and Chestnut Streets in Center City (downtown) Philadelphia, as proposed by one condominium developer, is quite rightly controversial. Opponents argue that it would add more traffic to an already-congested corner and encourage people to drive to and around Center City, which in turn would generate more greenhouse gases and increase fuel consumption. On the other hand, supporters of the project argue, the city needs more parking to attract visitors from the suburbs who will not take public transit or walk long distances to get to events on the Avenue of the Arts (Broad Street), which is just around the corner from the proposed garage, or to Center City restaurants and other attractions. And the city needs the suburban visitors.

This is not an easy balance to strike. The city does need the visitors. But the city also needs to survive and thrive in an era when travel by private car will become more expensive and difficult than it is today—and when climate change will almost certainly force us to restrict our use of private cars. Market pressures and legal requirements make the situation even more problematic. In the short term, plenty of parking is a marketing plus; in the long term, easy access to public transit may be a selling point. And in the short term, city ordnances require off-street parking for large residential building projects. (The parking garage project began as a condominium project that could not generate funding—hence the inclusion of off-street parking in the original plan.)

Whatever city ordnances and market pressures may dictate, however, lack of parking is not the problem that the "more-parking-is-better" mantra makes it appear to be. A quick search of Center City using Google Maps shows that there are already at least 531 parking facilities in Center City. Some of them, including the parking lot that is currently at 15th and Chestnut, are surface facilities that eat up space and destroy the cityscape. Most are multi-story buildings, some with retail on the ground floor, others with nothing at street level but a blank wall. At 15th and Spruce Streets, just three blocks south of the proposed garage, there is an extraordinary structure half a city block square that consists of a large tavern with ten stories of parking on top—making it possible to drink and drive in one convenient stop.

If parking is not the problem in Center City, what is? The simplest answer is also the truest: jobs. The population of Center City is growing; the economic base is not. And a parking garage at 15th and Chestnut Streets will not reverse this trend. Even with retail stores on the ground floor, it will house fewer jobs than the building that occupied this space before a major fire destroyed it in the 1980s. The good of the city would be better served by commercial development on this site—ideally, retail on the ground floor, with no more than 10-12 stories of offices above it to fit in with the rest of the Chestnut Street corridor. The problem is attracting the jobs.

Philadelphia, it must be said, provides a difficult environment for business because of its eccentric tax structure and bewildering bureaucracy. In the long run, however, merely ending these barriers will do less for the city than a good development plan that balances commercial, residential, and transportation projects to maintain a vibrant, walkable center that people can reach without resorting to their cars.

Philadelphia is not the only city that needs planning like this. In the future that is coming, public transit will become more important. Walkable business districts will become vital. And living closer together in viable neighborhoods will be a necessity. We could choose not to move in these directions: to build more and more parking lots and big-box stores, let our public transit fall to pieces, and ravage our cities in the name of storing millions of private cars. If we do, the odds are against our having a long-term future at all. But we will have plenty of parking.

Design for What? Second of Three Parts

The problem with designing a building is that it is a lasting monument. If it is beautiful, works with its surroundings, and moves us toward a better future, we will enjoy it for a long time, and it will help us to live better. If it is mediocre, ignores or destroys its surroundings, and lessens the prospect of a better future, we may tolerate it, but we will not love it—and in the end, when it has outlived its usefulness, we will have the problem of what to do with it.

All over the United States there are buildings like the big box store in the photo, the shopping mall outside of town that has effectively destroyed the central business district, and the office park that might once have been located in the city center. All are surrounded by acres of parking lots which damage water runoff, speed climate change (both by encouraging more cars and more driving, and by paving over farmland and green areas), and create traffic congestion. But in the suburbs, where most big boxes and office parks are located, parking, however ugly and destructive, has up to now been a sine qua non—an absolute necessity because shoppers and workers must drive their cars to reach the big box that is their destination. They have no alternative.

Older cities like Philadelphia provide alternatives to the private car. Public transit in Philadelphia is inadequately funded, does not run frequently enough, and follows routes that are often based on a city that once was, not the city that exists—but it is there, and it is quite possible to live in the city without a car at all. The difficulty for city planners is that the city needs to attract suburbanites for shopping, events, and jobs if it is to thrive. And suburbanites are not only in the habit of driving everywhere, they actually fear the city (any city, not just Philadelphia) at night. Or at least they fear the process of getting to and from downtown, or find it inconvenient,

In fact, it is inconvenient to drive from the suburbs to downtown, not because of parking but because of traffic. The local news in every city in the United States, not just Philadelphia, has regular reports on traffic jams—a daily crisis that everyone regards as normal even though it plainly is not. Hearing these reports, I regularly wonder why people subject themselves to the torture of driving to the city. The train is leisurely, comfortable, and quiet. It seems expensive, but compared with driving it is not. But there are few trains, they run at awkward times, and they stop running too early. Hence the choice of the slow, unpleasant, noisy, expensive drive to town.

Which brings us back to the proposed parking garage at one of the busiest intersections in downtown Philadelphia. From an environmental and social point of view, a ten-story parking garage like the one proposed is hard to justify. Less diplomatically, it is a disaster. It uses precious city space that could house offices or residents to house cars. It encourages driving to the city, and its location will inevitably increase traffic congestion.

That is the case against the proposal. The case for it is that the city "needs more parking" if it is to attract business from the suburbs. The real question, however, is whether, in the long run, the city will need more parking or better and more efficient access to its events and services. More and more parking seems important for the next five or ten years. But during those years, the price of fuel will go up, the supply will almost certainly go down, and the need to discourage driving (because of climate change) will become even more apparent than it is now. In the long run, the suburbs themselves will have to change or face ruin as the sheer cost of living in them and supplying them grows beyond what those who live there can sustain.

Given a long term in which suburbs become less viable (unless they also change), should city planners approve parking whose importance will probably diminish after five or ten years? And in any case, is a parking garage on one of the most important parcels of city land a good choice? More on this in the third posting of this series.

Design for What? First of Three Parts

One of my favorite blogs is Skyline Online, by the Philadelphia Inquirer architecture critic, Inga Saffron. Saffron's postings and the discussions that follow range from the aesthetics of new buildings to Philadelphia city planning to climate change and back—a stimulating and worthwhile experience for anyone concerned about these issues.

A recent Skyline Online posting reported that a Philadelphia developer, unable to find enough potential tenants for a proposed condominium at 15th and Chestnut Streets, had now decided to build the project in two stages: a "beautiful" (the developer's word) ten-story parking garage in the next two years, and the rest of the condominium later.

Two-stage projects like this in Philadelphia—and presumably in most cities—tend to remain at Stage 1 indefinitely. In effect, the developer was proposing to build a permanent parking garage at one of the busiest intersections in downtown Philadelphia (Center City, in local terminology). The local planning commission, which seems to love parking above all else, was likely to approve the two-stage project, although the newly-appointed city planning commissioner later said that because planners had approved the garage only as part of the condominium project, approval would not necessarily be a foregone conclusion.

Comments on the posting range from those who saw the proposal as a disaster to those who argued that the building itself looked nice and that more parking was an unalloyed benefit because no one from the suburbs would come to Center City unless they could park. My own position was the former—in fact, I was the first to use the term "disaster."

The whole discussion raised a deeper question: What does it now mean to say that a building (or a city block, or a machine like an automobile, train, or bus) is well-designed? The parking garage makes a pretty picture in the architect's rendering, although whether it harmonizes well with the buildings near it is hard to tell. But its impact on the environment, both natural and man-made, is likely to be very unattractive indeed. Is a nice building that destroys the natural environment and causes more traffic congestion really well-designed?

That is a hard question, too hard for one short posting. The scientific consensus is that every additional mile we drive places greater and greater burden on the environment. This is true both of private cars and of buses without adequate pollution controls—but the private car is far less efficient at moving people than the bus. And both transport modes are less efficient, and therefore more of an environmental hazard, than rail.

Can a building that is beautiful (or at least not ugly) really be well-designed if it does not take into account its overall impact? And how do we balance the environmental destruction that one more parking garage will encourage with the potential loss of business from suburban dwellers who will not visit the city unless they can drive there and park?

It is not an easy balance to strike. I have no clear answer. But in the next two postings, I will try to weigh the factors and consider them in the larger context of the future of climate change and resource limitations which is moving toward us faster than we could have imagined even five years ago.

The Economics of Green

A recent report by the leading economic and strategic analysis firm PriceWaterhouseCoopers, The World in 2050, argues that, contrary to U.S. government assertions, reducing the world's carbon emissions 60% by 2050 would have little economic impact—and might have substantial economic benefits—if we did it right. The report compares several scenarios, with the emphasis on two of them, and concludes

The projections demonstrate that if countries sit back and adopt a "business as usual" approach, the result could be a more than doubling of global carbon emissions by 2050. Based on current scientific thinking, this could have potentially serious longer term implications in terms of global warming and related climate change.

On the other hand a scenario such as the "Green Growth Plus" strategy outlined in the report could allow for continued healthy growth whilst controlling carbon emissions.The Green Growth Plus strategy

incorporates possible emission reductions due to a greener fuel mix, annual energy efficiency gains over and above the historic trend, and widespread use of carbon capture and storage (CCS) technologies. Of the scenarios considered in the report, only this ‘Green Growth Plus’ strategy stabilises atmospheric CO2 concentrations by 2050 at what the current scientific consensus suggests would be broadly acceptable levels.
The greener fuel mix considered in the report includes nuclear power, biofuels, and alternative power sources like wind and solar. It is, according to PriceWaterhouse, a strategy for maintaining prosperity without destroying the planet.

In the long run, we will have to develop a new type of prosperity that does not depend on growth. But without change along the lines suggested by PriceWaterhouse, we will not get to the long run. Green Growth Plus is not the ultimate solution to the problem of living with limitations, but it or something like it would be a step in that direction. And it is far more sane and hopeful than business as usual—the old style of growth that is slowly killing us.
