Infrastructure Indicator
This indicator unpacks macro-statistics to reveal
an ongoing debate: to what extent the USA has been overlooking the
vital role its infrastructure plays in undergirding our economy.
The August 2003 power blackout, as well as the terrorist attacks
of 2001 revealed many inadequacies in our infrastructure and public
services, from the security of airlines, airports and postal system
to that of water and electricity supplies, bridges, dams and the
state of our public health system. A new debate on the mix of US
transportation has revived interest in rail systems and the relative
subsidies to airlines and the need to balance our public investments
between roads, rail and air transport. Growing media attention to
sprawl has focused on the problems of relying on automobiles as
the main mode of transport. This reliance leads to ever-larger communities,
burgeoning suburbs, costly new highways and other infrastructure,
while increasing taxes, pollution and inconvenience.
Historically, infrastructure referred to highways,
railroads, harbors, bridges, aqueducts, public buildings, dams,
and the like. As our industrial societies evolved, we added airports,
communications systems, energy supplies, water, and other utilities.
Today, we think of infrastructure as including education, research
and development, computerized "backbone" systems, and
all taxpayer-supported systems that we use in commerce and on which
large sectors of our economy rely. A trend picked up by our indicator
is the privatization of growing areas of our formerly publicly owned
infrastructure, including electric utilities, phone, water, and
other services. Such publicly-funded investments used to be "expensed"
items in our GDP accounts. As of 1996, a more realistic asset budget
in GNP now accounts for such investments as assets, i.e., "savings"
since they often have a useful lifetime of 50 to 100 years or more.
This accounting change contributed to the budget surpluses of the
late 1990s, 2000 and 2001.
Another key infrastructure issue, triggered by
the recent blackout and California's energy problems is privatization
and the extent to which this leaves electricity transmission lines
"orphaned" and obsolete. Either these nationwide grids
will have to be linked into a more efficient, coherent system (requiring
enormous public and private investment), or power consumers will
continue to move off the grid with on-site generation. This trend
to decentralized electrical power is accelerating as fuel cells
are offering more efficient on-site generation and centralized electric
utilities see their future more as power "bundlers" and
distributors rather than running huge generating facilities -
a scenario I foretold in Planning Review, May 1974. Water
is another serious issue as well as its security, as even more users
add pollution and compete for finite supplies. In some areas ground
water is being pumped at twice the rate that rainfall can re-charge
underground aquifers.
The Infrastructure Indicator
is related to most other indicators, as infrastructure is the key
to energy-efficiency, whether our cities sprawl over virgin lands
and farms, or whether we infill older or vacant land in our cities.
These factors, in turn, relate to environmental protection, pollution,
housing, education, public health, and safety.
