NUCLEAR PLANT SITE WILL HOST REGION'S
LARGEST
SOLAR-ELECTRIC INSTALLATION
An abandoned nuclear power plant site in south-central Washington will
soon begin producing electricity--from the sun, not from splitting
atoms.
The Northwest's largest solar-electric installation, with a projected
capacity
of 35 kilowatts to 50 KW, is planned for the WNP-1 nuclear plant site
in
the Tri-Cities area. This solar undertaking is a joint venture of
Energy
Northwest, Bonneville Power Administration, Bonneville Environmental
Foundation,
Western S.U.N. Cooperative, at least one corporate sponsor and the U.S.
Department of Energy. "Everyone talks about solar but no one ever does
it," said BPA's Tom Osborn. Solar energy is widely considered too
expensive,
as was wind power a decade ago, he noted.
"We have to start somewhere." Energy Northwest will own and operate
the solar plant, according to an April 20 news release. At least some
of
the proposed 50-KW capacity--perhaps half--could be installed as early
as July. Estimated energy production is 80,000 kilowatt hours annually
when the project reaches full size. This represents "an important step
forward for solar energy in the Northwest," said Rachel Shimshak of
Renewable
Northwest Project in the news release. "Taken together with the several
hundred megawatts of new wind energy now in the pipeline, it is
evidence
that renewables are ready."

THREE BUSINESSES COMMIT TO 100-PERCENT NEW
RENEWABLE
ELECTRICITY
Three Puget Sound-area companies will voluntarily pay more for their
electricity in support of renewable energy. The three
enterprises--Xantrex
Technology, Batdorf & Bronson Coffee Roasters and Global Energy
Concepts--will indirectly buy all their electricity from renewables
under
milestone agreements announced in early April. These are reportedly the
first Northwest companies to commit to 100-percent new renewable energy
via "green tags" procured through the Bonneville Environmental
Foundation.
The green tag purchases by the three western Washington businesses will
help finance new renewables for the regional grid, via BEF. BEF
president
Angus Duncan called this "a truly extraordinary commitment" by the
three
companies. "They are exemplars for other folks in the region who have
the
same impulses but haven't acted upon them," he said at an April 4
ceremony
at Snohomish PUD headquarters in Everett. Company officials cited
business
as well as philosophical reasons for paying electricity premiums
estimated
in the range of 2 cents per kilowatt-hour. Xantrex--which, based on
that
number and its 2000 consumption, will pay approximately $20,000 more
annually for power at its manufacturing plant in Arlington--will use
clean energy as a marketing tool. The maker of power inverters for
renewable
systems will affix a logo declaring its 100-percent green energy status
to all products shipped out of the factory.

OREGON IOU RESIDENTIAL CUSTOMERS CAN SOON
CHOOSE
RENEWABLES
RATE OPTION
Residential electric customers of Oregon investor-owned utilities will
soon be able to choose a time-of-use rate, one of several green
resource
rates, or an environmental mitigation rate, in addition to the
traditional
cost-of-service rate now offered by Portland General Electric and
PacifiCorp.
The Oregon Public Utility Commission on March 20 approved the
new portfolio of options, which will also be offered to small
non-residential
customers, beginning Oct. 1. Oregon's electric industry restructuring
law
requires the two IOUs to offer a market-based option and at least one
renewable
resource rate by the October deadline. Actual tariffs for the rate
options
still must be developed and some of the finer points worked out, but
members
of the Portfolio Advisory Committee, which developed the options, are
pleased
with the proposal. So are renewable energy advocates. "This portfolio
will
allow smaller utility customers meaningful choices that will further
stimulate
the market for renewable energy," said Peter West, assistant director
of
Renewable Northwest Project, in a news release. The next step is for
the
OPUC to approve a bidding process for the renewable resource options,
according
to OPUC
senior utility analyst Rebecca Hathhorn, who served on the advisory
group. This bidding process should occur "extremely
expeditiously,"
she said, as the utilities must file tariffs for the new options by
June
1.

NORTHWEST UTILITY ENERGY SAVINGS DROP 40
PERCENT FROM 1997 TO 2000, RTF SURVEY FINDS
Utility-reported energy savings in the Pacific Northwest dropped nearly
40 percent from 1997 to 2000, according to a newly released survey by
the
Regional Technical Forum. The RTF study further documents the decline
of
energy conservation across the Northwest since the mid-1990s. It found
collective utility-reported savings of 49.91 average megawatts in 1997,
36.56 aMW in 1998, 35.06 aMW in 1999 and 30.61 aMW in 2000. Meanwhile,
utility-reported conservation spending plunged from $86.7 million in
1997
to $54.4 million in 2000, a drop of about 37 percent. These downward
conservation
trends do not uniformly apply to the 105 Northwest utilities hat
responded
to the survey--some actually increased their energy savings over the
four-year
period. In addition, the RTF's utility-supplied data are somewhat
inconsistent
and incomplete across the region. This is a "more cursory" summary than
the Green Books assembled by the Northwest Power Planning Council in
the
early- to mid-1990s, acknowledged RTF member Ken Corum of the Council.
It's probably accurate regionwide within a margin of error of 10 to 15
percent, he said. Nevertheless, Corum told Con.WEB, "The general shape
of what's been going on in the way of conservation is reasonably
well-reflected
here. It's much lower than it was in the mid-1990s." But he also
expects
regional conservation numbers to rise again in the next two to three
years.
RTF survey tells a tale of declining conservation.

"To imply that we're flattening Appalachia is so untrue. We're creating level land for Appalachia."
-- Bill Caylor, president of the Kentucky Coal Association, claiming that the destructive practice of mountaintop removal mining- blowing the tops off mountains to get at the coal beneath- performs the "necessary" function of creating flat land for development.
BONN, Germany, December 4, 2001 (ENS) - The reservoirs of the world are losing their capacity to hold water as erosion brings silt down to settle in behind dams, the chief of the United Nations Environment Programme (UNEP) warned today.

The potential of wave energy is big. We mean, really, really big. How big? Consider this: A sliver of ocean, roughly the size of Lake Washington, could power the entire state of Washington. No wonder a worldwide race is shaping up to harness all this power. And our state of Washington is in the middle of the action.
So How Does This Wave-Energy Stuff Work?
These are interesting times for wave energy. The energy stored in ocean waves is enormous -- easily able to rival wind or coal or nuclear as a major energy source. The $64,000 question is how to build the best gizmo to capture that energy. Lots of different technologies and lots of talented engineers are in the hunt.
So here's what happens:
A wave crest sweeps under the buoy and forces it
up. The huge, 7-foot-diameter acceleration tube is attached to
the
buoy, so it also rises. The top hose pump is attached to the top
of the acceleration tube, so it has to rise, too. However, the
other
end of the top hose pump is attached to the piston, which has a massive
amount ow water sitting on top of it (all the water in the
7-foot-diameter
aceleration tube.) That piston does not want to move, at least
not
anywhere near as fast as the buoy.
The top of the hose pump rises with the buoy, but
the bottom of the hose stays put with the piston. That means the
tube has to stretch, which it can do because it's rubber. When
the
hose pump stretches, its inside space is compressed, forcing the
seawater
in the hose to squirt out a pipe at the top. A check valve
prevents
water from squirting out the bottom of the hose pump. The force
of
this expulsion drives a Pelton wheel turbine, producing electricity.
Now, as the wave passes and the buoy drops into
a trough, the acceleration tube also drops, pushing down on the top of
the hose pump. But the piston still remains pretty much unmoved,
so the hose pump is compressed, which expands ints internal space and
allows
more seawater to rush in. At the same time, the lower hose pump
is
stretched, and it squirts out water into the same pipe that leads to
the
turbine. This way, for each stroke up or down by the
buoy/acceleration
tube, water will be expelled into the turbine.
This sounds simple, but the engineering is complex,
and this design has never been tested in the ocean. The rest of
the
process uses proven technology -- the transmission of the electricity
to
shore via underwater cable. The multi-speed tubine produces
"wild"
alternating current electricity (unsynchronized AC of varying
frequency,
or cycles per second). This AC is rectified to direct current
(DC)
and routed to shore by a high-voltage DC cable. Once on shore,
the
DC is run through an inverter and converted to AC electricity of proper
hertz and phase and delivered to the power grid.
The HVDC cable is a better way to transmit
electricity
underwater because, unlike AC, DC is largely unaffected by the high
capacitance
of long undersea cables. Underwater, AC cables produce a strong
electromagnetic
force field that drains power. That problem is avoided with HVDC
cables. And DC transmission avoids the extremely low frequency
electromagnetic
force fields that are controversial for their effects on health.
That may be good news for the clams.

The main light source of the future will almost surely not be a bulb. It might be a table, a wall, or even a fork. An accidental discovery announced this week has taken LED lighting to a new level, suggesting it could soon offer a cheaper, longer-lasting alternative to the traditional light bulb. The miniature breakthrough adds to a growing trend that is likely to eventually make Thomas Edison's bright invention obsolete. LEDs are already used in traffic lights, flashlights, and architectural lighting. They are flexible and operate less expensively than traditional lighting.
Happy accident
Michael Bowers, a graduate student at Vanderbilt University,
was just trying to make really small quantum dots, which are
crystals
generally only a few nanometers big. That's less than 1/1000th the
width
of a human hair. Quantum dots contain anywhere from 100 to 1,000
electrons.
They're easily excited bundles of energy, and the smaller they are, the
more excited they get. Each dot in Bower's particular batch was
exceptionally
small containing only 33 or 34 pairs of atoms. When you shine a light
on
quantum dots or apply electricity to them, they react by producing
their
own light, normally a bright, vibrant color. But when Bowers
shined
a laser on his batch of dots, something unexpected happened.
"I was surprised when a white glow covered the table," Bowers said. "The quantum dots were supposed to emit blue light, but instead they were giving off a beautiful white glow."
Then Bowers and another student got the idea to stir the dots into polyurethane and coat a blue LED light bulb with the mix. The lumpy bulb wasn't pretty, but it produced white light similar to a regular light bulb. The new device gives off a warm, yellowish-white light that shines twice as bright and lasts 50 times longer than the standard 60 watt light bulb. This work is published online in the Oct. 18 edition of the Journal f the American Chemical Society.
Better than bulbs
Until the last decade, LEDs could only produce green, red, and yellow
light, which limited their use. Then came blue LEDs, which have since
been
altered to emit white light with a light-blue hue. LEDs produce twice
as
much light as a regular 60 watt bulb and burn for over 50,000 hours.
The
Department of Energy estimates LED lighting could reduce U.S. energy
consumption
for lighting by 29 percent by 2025. LEDs don't emit much heat, so
they're
also more energy efficient. And they're much harder to break.
Other scientists have said they expect LEDs to eventually replace standard incandescent bulbs as well as fluorescent and sodium vapor lights. If the new process can be developed into commercial production, light won't come just from newfangled bulbs. Quantum dot mixtures could be painted on just about anything and electrically excited to produce a rainbow of colors, including white. One big question remains: When a brilliant idea pops into your mind in the future, what will appear over your head?
The UN climate change negotiations, now getting under way in Delhi,
have focused international attention once
more on the problem of global warming.
Experts agree there is a need to switch to renewable forms of energy
if production of greenhouse gases is to
be curbed. Now an Icelandic team has invented a radical device which
can produce electricity from water.
The Thermator could play a major role in the non-polluting economies of the future.
The Thermator contains a semi-conductor crystal ©Varmaraf
It works by something called the thermo-electric effect, which scientists have known about for many years.
But while thermo-electric generators have mainly been used to power
spacecraft, such as Voyager and Galileo
using heat from radioactive materials, the Thermator is firmly rooted
on Earth and works on nothing more than
hot water.
Professor Thorstein Sigfusson, of the University of Iceland, says it
works by translating the difference between
the temperature of hot and cold water into energy.
He explains: "In between the hot and the cold side are crystals made of semi-conductors.
"As the heat is transferred through these crystals part of it is converted from heat energy into electric energy."
Professor Sigfusson said there was potential for using all sorts of
excess heat to fuel Thermators and he
added: "In car engines for example, only a fraction of the heat
produced
is turned into propelling energy."

Despite their substantial energy saving benefits,
compact fluorescent light bulbs (CFLs) present a unique challenge for
the
environmental and energy efficiency communities. Even though CFLs
contain
only a very small amount of mercury – about 100 times less than an
average

and mercury-reduction advocates, are working to keep large
accumulations
of bulbs out of landfills. Utilities can play a leading or supporting
role,
a choice that needs to be made on the local level.
The CFL Disposal Kit was developed to help utilities
understand this issue by reviewing the role of mercury in fluorescent

Eying alternative energy

DAILY NEWS STAFF WRITER
President Bush said in his State of the Union speech that he wants
to
reduce our oil imports from the Middle East by at least 75% by 2025.
Currently, Middle East oil fuels about 10% of America's energy needs,
mostly for transportation.
Some of the technologies that Bush mentioned — such as clean coal, solar, wind and nuclear — would be used mainly to produce electricity, so they wouldn't make much of a dent in the country's oil addiction.
So how realistic is the President's goal? Here's a look at the
emerging
technology:
Cellulosic ethanol
This type of ethanol is made from switch grass, sawdust and other plant
waste, and it is chemically identical to conventional ethanol, made
mostly
from corn. Ethanol mixed with gasoline can be used in cars and trucks
on
the road today without any modification.
However, the technology and production infrastructure are still in their infancy. Companies would need to build multimillion-dollar plants relatively close to farms to make cellulosic ethanol economically feasible.
"It's going to need a dramatic infusion of dollars to make it happen," said Marchant Wentworth, a clean-energy specialist at the Union of Concerned Scientists.
Grain ethanol has been around for more than a decade, but it still
accounts
for only 2% of what goes into gas tanks.
Hydrogen
This lighter-than-air gas powers vehicles or generators that have fuel
cells, which have virtually zero tailpipe emissions, aside from plain
water
vapor. But unlike ethanol, using hydrogen would require not only
entirely
new vehicles, but also an entirely new infrastructure, including plants
that make hydrogen (by using electricity to extract hydrogen from
water)
and "gas" stations that sell it. Fuel cell-powered cars already exist,
but they are mostly experimental and are far from mass production.
"It's so far in the future that it's not something you can hang your
hat on right now," said Karen Wayland, an energy specialist at the
Natural
Resources Defense Council.
Clean coal
Coal accounts for 23% of U.S. energy needs and 52% of U.S. electricity
production, but it creates a lot of pollution. High-tech power plants
can
turn coal into a gas and take out pollutants such as mercury and
greenhouse
gases such as carbon dioxide from the exhaust. The President has
proposed
spending $218 million more next year — an increase of 22% — on research
and development for such technology. But experts said it's not enough
to
make it an everyday reality by 2025.
"Clean coal does exist, but it's no more cost-effective than solar
power,"
said Severin Borenstein, an energy economist at University of
California
at Berkeley. "A 22% increase in funding is just not a Manhattan
Project-type
effort that we need."
Nuclear and hydroelectric
Environmental concerns and the immense cost of building these types
of power plants mean there is virtually no projected growth in these
sources
without major policy shifts. Nuclear power accounts for about 8% of
U.S.
energy needs, and hydroelectric power, about 2%.
Solar and wind
These sources account for barely two-tenths of a percent of U.S. energy
needs.
"It could increase vastly, but it depends entirely on policy," Borenstein said. Solar technology in particular is expensive. It costs about 35 cents to produce a kilowatt-hour of solar power, compared with about 5 cents for coal and 9 cents for wind. Solar power isn't for every region, and it wouldn't be feasible in the New York area.
Wind power could be harnessed almost anywhere in the country, including the Appalachian Mountains and on – or off – Long Island.
If this breakthrough, which has actually been around for a couple of
years now, lives up to its claims, we are indeed on the verge of an
absolutely
major revolution in the world energy scene! In a similar
arena,
I have been corresponding with a company in New Zealand seeking to
manufacture
a TPV cell (developed by a Boeing engineer!) that can convert thermal
energy
(from my biomass-fueled furnaces) quietly
into
electricity at theoretically 100 times the energy density of solar
cells.
Lots is happening to unseat king oil from the despot’s throne in the
near
future. Read the two articles below.

SA solar research eclipses rest of the world
Willem Steenkamp
February 11 2006

In a scientific breakthrough that has stunned the world, a team of South African scientists has developed a revolutionary new, highly efficient solar power technology that will enable homes to obtain all their electricity from the sun. This means high electricity bills and frequent power failures could soon be a thing of the past.
The unique South African-developed solar panels will make it possible for houses to become completely self-sufficient for energy supplies. The panels are able to generate enough energy to run stoves, geysers, lights, TVs, fridges, computers - in short all the mod-cons of the modern house.
Nothing else comes close to the effectiveness of the SA invention. The new technology should be available in South Africa within a year and through a special converter, energy can be fed directly into the wiring of existing houses. New powerful storage units will allow energy storage to meet demands even in winter. The panels are so efficient they can operate through a Cape Town winter. While direct sunlight is ideal for high-energy generation, other daytime light also generates energy via the panels.
A team of scientists led by University of Johannesburg (formerly Rand Afrikaans University) scientist Professor Vivian Alberts achieved the breakthrough after 10 years of research. The South African technology has now been patented across the world. One of the world leaders in solar energy, German company IFE Solar Systems, has invested more than R500-million in the South African invention and is set to manufacture 500 000 of the panels before the end of the year at a new plant in Germany.
Production will start next month and the factory will run 24 hours a day, producing more than 1 000 panels a day to meet expected demand. Another large German solar company is negotiating with the South African inventors for rights to the technology, while a South African consortium of businesses are keen to build local factories.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
More details of the technology are given in this article:
http://cooltech.iafrica.com/features/508857.htm
This article has been reproduced from the SA edition of
Popular Mechanics.
Solar cell technology has remained essentially unchanged since the phenomenon was first noted in the 1800s. The standard for today’s devices is still the silicon-based panels that have been steadily refined over the past half-century. Present conversion efficiencies are between 10 and 15 percent. In direct sunshine you can bank on between 100 and 150 watts per square metre of panel.
How to improve on that? Consider this telling comparison: a typical conventional panel uses silicon slabs over 350 microns thick because of the material’s poor absorption properties; the Alberts method produces a five-micron film. That’s a quarter of the thickness of a human hair.
So it’s thinner. That doesn’t necessarily make it better. But it is. “Let me put it this way,” says Alberts. “From the solar energy point of view, what we have developed is the best-absorbing material known to us.” Not only that, but it’s cheaper to produce.
He is talking about a patented semiconductor material, copper indium gallium selenium sulphide or Cu(In,Ga)(Se,S)2 for short. Five elements that, taken separately, are pretty pointless as collectors of sunlight. But then they’re subjected to a bit of high-tech alchemy… or should that be domestic science?
“You know, it’s a recipe… the whole thing is much like baking bread,” he says. “You start off with ingredients that have certain characteristics, and after mixing, preparing and baking you have a product whose characteristics are completely different to what you started with.”
Professor Alberts says the thin film technology he and his team developed can generate up to 150 watts of electrical power at a cost below R10 per watt peak. He adds that it has demonstrated not only high efficiency, but also long-term performance stability. “The pilot plant demonstrated that these thin film solar modules could be produced by highly scalable and proven industrial technologies such as physical vapour phase deposition and diffusion processes.” Commercial-scale thin film modules are being produced with output powers between 10 and 40W in direct sunlight.
<>Quoted costs of R10/Wp look highly favourable against the cost of “traditional” electricity. And better still against the R35 per watt production cost of conventional modules. The import price locally of a silicon-based 50W solar panel is about R2000 (R40/Wp).> Back to TOP
