A study released by the American Gas Assn. suggests that increased research
and development of natural gas and alternative sources and a freer energy market
could cut the nation's carbon dioxide emissions by 10% by the year 2000. The
study advocates dropping state and local free market "barriers" such as those
requiring emission scrubbers for electric power plants, or mandatory use of
coal. Instead, it relies on higher efficiency appliances and doubling the use of
renewable sources-including solar, geothermal, biomass and wind-while increasing
use of natural gas by 40% by 2010. This would reduce oil imports and increase
domestic employment in both the oil and gas industry and in energy conservation
and renewable energy. The study estimates the creation of from 200,000 to
400,000 new jobs in renewable energies and energy conservation alone. Persons in
the coal industry, however, say that it would merely shift jobs to other
sectors. [Parrish, M. (1992, May 1). Energy coalition pushes an 'alternative
future'. The Los Angeles Times, p. D2.]
The Danish government is pushing ahead with one of Europe's most ambitious
alternative energy projects-a pro gram that would make Denmark the first country
in the world to use wind power as a significant contributor to its national
electricity grid. At the present, only California has installed greater
wind-power capacity. Denmark is in the final stages of an initial expansion that
will triple its wind power by the end of the next year to cover nearly 10% of
its electricity requirements through wind energy. Denmark and California
together produce 90% of the globe's wind-generated electricity. [Marshall, T.

Times, p. H4.]
According to Greg Rueger, general manager of the nation's largest
investor-owned utility, Pacific Gas and Electric Co., the newest generation of
wind-power turbines already can match fossil fuel facilities on price. Rueger
estimates that the newest, third-generation windmills, if mass produced, could
make electricity at a lifetime cost of S.S to 6.S cents per kilowatt-hour in
good wind areas. That compares with 7 cents an hour for a new gas/oil filed
plant in the PG & E service area. Solar generation still costs around 10 cents
per kilowatt hour, although that too is dropping. A recent project may have
produced equipment that lowers the cost to 8 cents. [Dillin, J. (1991, March
14). The Christian Science Monitor, p. 26.]
Edison and Texas Instruments recently announced a solar technology
breakthrough. A relatively low-cost solar photovoltaic cell has the potential to
provide one-third of an average home's electricity using a 10-by-10 foot rooftop
panel! [Bryson, J.E.(1991, May 19)Change is in the wind- and the sun. The
Los Angeles Times, p. M5.]
A biomass plant, operated by Delano Energy Co., takes 700 tons of prunings,
fruit pits and waste wood a day from nearby orchards and burns them in a
state-of-the-art furnace that emits fewer emissions than an old-fashioned
wood-burning stove. The resulting heat is used to make steam that drives
turbines. Enough electricity is generated to serve the needs of about 30,000
California households a day. The Delano power plant produces energy at a cost of
roughly 8 cents per kilowatt hour, making it close-to competitive with coal
(about 5 to 7 cents per kilowatt-hour) and natural gas (5.5 cents). But the
biomass plant was only able to get financing in the first place because state
incentives encouraged utilities to buy power from such plants at rates above
market levels. More dollars are needed for help in construction of such plants.
Biomass plants are among several so-called renewable energy technologies that
proponents argue hold the greatest promise for replacing the fossil fuels and
imported oil this country uses to generate power. [Lee, P. ( 1 99 1, March 26).

A new $700 million Federal fund has authorized a six-year demonstration
program to explore magnet power for trains . This type of train would have no
locomotive but would be lofted above its track by a magnetic cushion and
propelled by a magnetic wave. These trains would travel at a very high speed,
with high efficiency and with little or no wear. Demonstration trains in Germany
have established a speed record of 273 miles an hour over a test track. Planners
in Florida hope to build a 14 mile maglev (magnetic levitation) train route from
Orlando airport to Disney World. The downside is that this Florida track is
estimated to cost S500 million. This technology is not cheap; that is the
present fly in the ointment. [Browne, M.W. (1992, March 3). New funds fuel
magnet power for trains. The New York Times, pp. C1, C11.]
A discovery by nuclear scientists at the Joint European Torus (JET)
laboratory at Culham, England has convinced scientists that fusion power will be
generating virtually limitless amounts of cheap, pollution-free electricity in
the 21st century. Unlike fission reactors, which split atoms to produce energy,
the Torus reactor pushed atoms of deuterium and tritium together to generate a
temperature of 200 million degrees C. In future years, scientists will face
challenges of designing, building, and paying for a working fusion reactor, as
well as containing impurities. International cooperative efforts are now in the
works to face future research challenges. If the necessary money can be
mobilized (approximately 3 billion pounds), the reactor could become operational
in the 21st century. [MacLeod, A (1991, November 20), Fusion power future looks
bright. The Christian Science Monitor, p. 12.]
Implications
Developing low-cost, pollution-free energy constitutes a major challenge to
research agencies, including research universities. When these efforts pay off,
resources traditionally directed to energy could be redirected to social issues,
health care and education. |
