00) --commentary--
It may be time for the idea of an 'energy tax' to be revisited.
It may already exist in some forms, yet it would not single out
any one person or industry in requiring doing more with less. A
possibility is that such a measure could reign in what is now an
unfettered growth in consumption, unrealistic with the costs of
this within even a few months time, less the years, decades ahead.
One of the issues that reoccurs is that someone will get hit with
an unfair restriction while others can freely profit. Yet, when it
is a question of all losing, all would have to have a stake in the
changes. In the .US (here) the .EU setup has been an example of how
to make such changes- it costs a lot more to drive a car, and the
result is a different kind of infrastructure and sensibility. So,
a precedent exists that a similar if not better future could exist
in terms of energy overconsumption, if some changes were enacted.
An 'energy tax' seems to be one such tool to move in this direction.
'Tax' is equivalent in today's rhetoric to 'sin' yet it would seem
that there to consume many times the amount of energy than others
should require paying more, if as a penalty to change behavior,
in order to make the economics of this damage realistic to the
ongoing issues of climate change, pollution, health hazards, etc.
There may be no way around it, if energy does get too expensive
to subsidize the wanton excess and hedonism of the technological
lifestyle, which depends on a very cheap supply for a great fix.
If, when, the economics change, it is likely much more will too
such as buildings, transportation, packaging, manufacturing, etc.
Which is good if it is able to happen through peaceful changes.

The Kerry Energy Plan
<http://releases.usnewswire.com/GetRelease.asp?id=163-03232004>
'John Kerry's energy plan will increase and enhance domestic energy
sources and provide incentives to help Americans use energy more
cleanly and efficiently. When 65 percent of the world's oil reserves
lie beneath the Persian Gulf states and only 3 percent lie beneath
America, we cannot drill our way to independence. We can, however,
develop and deploy clean energy technologies that will make us more
efficient and allow us to capitalize on domestic and renewable sources
of energy.' .. 'John Kerry's plan includes a renewable energy trust
fund that will fund the development of renewable energy, reducing our
oil dependence by more than 2 million barrels of oil a day - about the
same amount we import from the Persian Gulf. Kerry's plan will also
create 500,000 new jobs over the next decade and work toward producing
20 percent of US energy from renewable fuels by 2020.'

Oil Gains as U.S. Fills Strategic Reserve // the importance of

<http://www.reuters.com/

'In Washington, U.S. Energy Secretary Spencer Abraham reiterated that
the government would not halt oil deliveries to the Strategic
Petroleum Reserve and said the price impact of the deliveries was
"nearly negligible" -- something most analysts agree with.' .. '"What
is really holding it up here is U.S. gasoline," said Barclays
Capital's Paul Horsnell. "But at these levels it doesn't take much to
generate a 60 or 70 cent move."'

'A rise in oil and gas prices has been a modest drag on the otherwise
strong US economy, but so far US consumers have not reined in spending
or driving despite the rising prices. Energy analysts say petrol prices
are almost certain to climb to $2 a gallon on average by summer, which
will test consumer resilience.' ... '"The market is going to make a run
at 40 bucks, that I can guarantee you," said Mike Driscoll, energy
trader at Bear Stearns.' .. 'Indeed, the days of the ceiling on oil
prices hovering at about $30 a barrel may be history.' .. 'The old
thinking used to be that if crude rose above $30 a barrel, it was
disastrous for the US economy. "We have to reset the benchmark - it may
be $40," said Mr Flynn.'
Bush chided for oil prices // note: 'energy legislation' is not

<http://www.washtimes.com/business/20040324-121402-7035r.htm>
'"We've ... made clear we're not going to beg for oil," said Mr.
Abraham, although he later told reporters that the administration has
been working behind the scenes to try to bring prices down.' ... 'AAA
announced yesterday that the price of regular-grade gasoline hit a
record at about $1.74 a gallon, though the country is still months away
from the peak summer-driving season, when gas prices normally are
highest.' ... '"It's an intolerable position," Mr. Kennedy said. "No
one can understand it ... why the president of the United States isn't
jawboning OPEC."' ... 'Energy analysts say it is extraordinary that gas
is hitting a record high during the customary spring lull in the oil
cycle, and it does not bode well for the summer.'

Treasury Is Faulted for Papers' Release

'The report by the inspector general, Jeffrey Rush Jr., said that
mislabeling had caused the release of the "national security or
sensitive but unclassified" material but that neither Mr. O'Neill nor
anyone in the department had broken any laws.' .. '"Had these 140
documents been properly marked as classified," the report said, "the
documents would not have been entered into Treasury's unclassified
computer system and O'Neill would not have received them."'

'A clinical trial is testing a neurostimulator to treat severe chronic
angina. Surgeons place an electrode in the epidural space of the spine
and attach it to a pacemaker-size battery implanted in the buttocks or
upper abdomen. It delivers a mild electrical current to disrupt pain
pathways.' ... 'The implanted pacemaker-like device called the

'~Eternal~Sunshine ... demonstrates a remarkably nuanced understanding
of how the brain forms memories, particularly memories about intense
emotional experiences. The film displays a more subtle model of memory
formation than the acclaimed thriller ~Memento,...' ... 'The fading of
memory in ~Memento is about the loss of pure information, like an
erased hard drive. In ~Eternal ~Sunshine , the richness of memory is as
much about emotion as raw data.' ... 'The emphasis on feeling over data
processing puts ~Eternal~Sunshine squarely in the mainstream of the
brain sciences today. We now know that the brain stores emotional
memories very differently from unemotional ones.' ... '~Eternal
~Sunshine plays on this idea of traumatic memories being stored in
separate regions of the brain...'

(UVA) light, until now considered to be less harmful than type B
ultraviolet (UVB) light, causes DNA damage and may trigger skin

tankers from entering U.S. ports if the ships fail to meet security
standards.' ... 'The new standards will kick in at the height of the

customers with rates and service regulated by the California Public
Utilities Commission.' ... 'Advocates of partial deregulation – known
in industry jargon as a core/non-core market structure – promise that
their new plans wouldn't allow big customers to escape their share of
crisis costs or the overhead of maintaining the state transmission and
distribution system.' ... 'Large power users, for their part, believe
they could get cheaper power deals if they were freed from the
requirement of getting service from their local utilities.' ... '[State
Senator] Dunn added that advocates of electricity re-regulation are
considering an initiative of their own, though costs are daunting.'
