Renewable
Energy - Finally, Acceptance? -
For years, on the
rare occasions that the mainstream media covered the topic of global
warming, it was usually with skepticism. When politicians like Al Gore
tried to convince the public of the need to conserve energy and develop
alternatives to fossil fuels they were ridiculed in print and on attack
radio. As crude oil approaches $100 per barrel, as islands experience
measurable loss of land to rising seas, and as Arctic tourists see the
shrinking icebergs and glaciers, more Americans believe that global
warming is real and that we must use alternatives to fossil fuels.
Judging from the requests for information that NJEL receives, there
is a public appetite for information about renewable energy sources.
As the media catches up with the public's interest in the subject, there
now seems to be constant coverage. Nevertheless, much of the public
is still unaware of the extent to which renewable energy sources (other
than burning wood) have been researched and used for decades. Right
now In New Jersey, private individuals are using wind power. Our Legislative
Director is advocating for zoning protections for small scale, single
windmills, that are at least equal to the protections given much larger
and more intrusive cell towers. There is a wave action study in progress
in New York's East River. To answer our members' questions, NJEL Board
members volunteered their time to research alternative energy topics.
With information presented at the Rutgers Energy Institute as a starting
point, this newsletter issue includes descriptions of the renewable
energy sources that are either in commercial use or are the subject
of serious research.
Rutgers
University Energy Institute

Daphne Speck-Bartynski & Anne Poole
A comprehensive
overview of renewable energy sources was presented at the Rutgers Energy
Institute (REI) Mini-Symposium in May 2007, which NJEL Vice President
Daphne Speck-Bartynski attended. There is now little disagreement among
mainstream scientists that the carbon dioxide produced by the use of
fossil fuels is a significant cause of global warming. Proposals for
sequestering carbon dioxide and using it to produce fuels are in the
news, but Institute Director Professor Paul Falkowski pointed out that
humans are a million times more efficient at extracting and burning
fossil fuels than they are at capturing and returning the resulting
carbon dioxide to geologic formations.
While storing, and
even using carbon dioxide to produce certain fuels may be part of the
solution for global warming, it is not likely to be a commercially viable
option soon. To reduce carbon dioxide emissions, humans have no choice
but to reduce their use of fossil fuels.
REI's symposium covered an array of renewable energy technologies that
went beyond the familiar topics of solar and wind power. Consumers need
to educate themselves about these technologies so that they can choose
energy products wisely. Consumers are also taxpayers and investors and
in those roles, they need to demand the economic and political policies
that will decrease the damage of global warming and ensure a sustainable
economy. Much of the symposium's subject matter was highly technical
but the program did provide basic descriptions of the various technologies.
As a speaker pointed out, New Jersey does not consume enough oil to
change the nation, but it does produce enough electricity to influence
the way that the nation produces its energy
In addition to the information provided at the Symposium, information
in the following sections came from the Solar Energy Society of Canada
(www.sesci.ca), the Electric Power Research Institute, (www.epri.com),
and the MIT Technology Review (www. technologyreview.com).
Photovoltaics- Conversion of light into electrical energy by the use
of semiconductors. Recognizable examples are solar panel installations
on buildings and solar-powered lights.
Active and Passive Solar Energy-While photovoltaics converts sunlight
into electricity, active and passive solar energy systems simply collect
and distribute the sun's heat. In a passive system, a steady supply
of solar energy is, simply, used, as in the sunlight coming through
a window. There is no mechanical intervention or assistance. In an active
system, pumps or fans are used to distribute the energy. Examples are
solar-powered building systems that provide heat and/or hot water.
Geophysical Fluids-include the elemental forces of wind and water. The
public is familiar with hydroelectric dams and waterfall sited power
plants. Although wind power accounts for a small share of electric production,
awareness of it is growing. Wind power installations have a variety
of configurations, from single windmills to wind farms composed of hundreds
of large turbines. Hydroelectric and wind power are used in Europe with
great success. These types of renewable energy could, when adopted in
New Jersey, create jobs and produce clean energy that is cheaper than
electricity produced from coal
The "water" category includes more than dams and waterfalls.
Water power includes wave, current, and tidal action, ocean thermal
gradient, and salinity gradient, energy. A variety of devices are in
place around the globe, being used to research and test electricity
generation by these methods. There are sites in South Africa, Scotland,
Ireland, Israel, Canada, Japan, and the U. S.
In the case of wave, current, and tidal action, machines to harness
that energy have taken many forms. Some with clever names like Wave
Dragon and Sea Clam have already been determined ineffective, while
others, notably the Sea Dog and the Pelamis Wave Energy Converter, show
considerable promise. One invention, the Tidal In-Stream Energy Converter
(TISEC) is in place in New York's East River for an 18 month test. The
test is to determine if the six underwater turbines, similar in design
to wind turbines, will have an impact on the River's fish.
Ocean thermal gradient and salinity gradient use the power latent in
differences in ocean temperatures and differences in salinity to generate
electricity. In the last three years, almost 60 applications have been
submitted to U.S. energy regulators for permits for water action installations.
Biovoltaics-Less familiar to most of the public, but with research in
progress, is the use of biological substances to produce energy or fuels.
Luminescent bacteria are being studied, as are types of algae that contain
an oil that scientists have dubbed "biocrude."
Geothermal- Literally, earth heat. Most people are aware of the use
of geothermal energy in Iceland, but geothermal energy, while a small
percentage of the total used on our globe, is widely dispersed. Most
of the user countries are in the Pacific Ring of Fire-Indonesia, Mexico,
New Zealand. There is usage in France and Italy. An interesting factoid
is that the first geothermal electricity was generated in 1904 in Italy.
You may be surprised to learn that of the 7000 megawatts of geothermal
electricity generated worldwide, a third is generated in the U.S. It
is used in New Mexico, Oregon, and California. There are five geothermal
electricity plants in Lake County, CA and the County has consistently
met or exceeded Clean Air standards. Geothermal energy is not totally
unintrusive, however, and there are some concerns about overexploitation.
Drilling and piping are required.
Biofuels-Probably the energy source that is now most covered by the
media. A subject that was found occasionally in the mainstream general
news, it is now a frequent topic in the business and investment media.
First generation biofuels are those produced from the fermentation of
starch, (ethanol from corn or cane sugar), or from oils (biodiesel).
Ethanol is now controversial because of the large amounts of water and
energy required to produce it. The demand for ethanol is also blamed
for high corn prices and the resulting rise in animal feed costs. Brazil,
which is oil-independent because almost all of its vehicles use biofuels,
accomplished it at the cost of transforming rain forests into farmland.
Second generation biofuels are produced from nonfoods, like plant cellulose
(grasses) and algae. There is an expectation that these can be more
efficient and environmentally benign than ethanol. ***********
Energy storage is crucial for solar and wind power because frequency
shifts create major changes in the energy grid. Frequency shifts are
caused by lack of sun, decreased wind, and clouds passing over photovoltaics.
A power grid needs energy storage capacity to offset such shifts . The
U.S. Department of Energy is increasing funding to develop better storage
so that when energy to the grid is decreased, stored energy can be used
to generate electricity without interruption. Nano-enabled storage looks
promising; additional advances are expected with lithium and lithium
ion batteries and negative electrode storage. ********
A good energy policy combines technology with economics and an appreciation
of the public policy making process. Under New Jersey's Global Warming
Response Act, which codifies an executive order issued previously by
Gov. Corzine, our state is required to reduce greenhouse gas emissions
to 1990 levels by 2020, a reduction of roughly 20% . This is not just
a plan, it is a mandate. Hopefully it will be met and, as the deadline
nears, will not be rolled back because of inaction.
Legislative
Update
- by
Michael L. Pisauro
Electronics Waste
Recycling - In 2007 the Legislature took up the issue of removing
certain electronic products from New Jersey's solid waste stream, recycling
electronic materials where possible, and disposing of hazardous materials
appropriately. To fund the recycling, fees would be imposed on electronic
products, with most of the funds forwarded to counties for carrying
out the recycling. Competing bills were introduced in the Assembly and
the Senate.
A notable difference between the bills was the point at which the recycling
fee would be imposed. The Senate version, S-554 would impose the fee
at the time of purchase, so that presumably the consumer would pay the
fee. The Assembly bill, A-3573, would impose the fees upon the manufacturers.
The fees would be calculated according to a formula using product weight,
percentage of hazardous material in the product, and the manufacturer's
market share. Under A-3573, the NJ Department of Environmental Protection
would be responsible for administering the formula-based fee system.
Some environmental and consumer groups favor A-3573 because it requires
manufacturers to pay the fee at the beginning of the product stream.
However, the NJEL Board was concerned about the bureaucratic apparatus
that would be required to administer the system, collect manufacturing
data, and audit that data. The effects of out-of-state sales, internet
sales and resales were not clear. It was also likely that manufacturers
would pass on the cost to he consumer, but the add-on would not be readily
transparent to the consumer. Finally, a fee at the time of purchase
would be expected to raise consumer awareness of the recycling program.
An argument that a fee based on the percentage of toxic materials would
encourage manufacturers to seek alternative materials does have merit,
but at the present time we are not convinced that it offsets the complicated
administrative framework that would no doubt develop. Neither bill includes
cell phones or devices with screens smaller than 4 inches (i.e., PDAs).
NJEL has requested that such devices be included.
Both bills have passed out of their respective Environment Committees.
Coastal &
Ocean Protection Council - After several years, the Coastal Ocean
Coalition (COC), comprised of both State and National environmental
groups, sees one of its agenda items moving closer to reality in New
Jersey. In 2003 and 2004, reports were released by two different national
commissions that reviewed the health of the nation's coasts and oceans.
The reports issued by the Pew Oceans Commission and the U. S. Commission
on Ocean Policy were not in complete agreement on all points, but both
concluded that the nation's coastal resources are in peril. In the face
of delays by the Federal government in implementing the recommendations
of the Commissions, the COC developed a plan of action that the State
has the authority to pursue. One of these elements was the establishment
of a Coastal Ocean Protection Council, a coordinating body that will
apply ecosystem-based management to our coastal regions. The Council
would be expected to balance what is best for the coastal ecology with
the competing utilization interests--tourism, fishing, surfing, construction
and, now, energy generation. One of the problems for coastal resource
management in NJ is the variety of state and local agencies that regulate
and monitor the coastal areas. This fractured framework is in itself
problematic.
*******
In June the Assembly Environment and Solid Waste Committee passed out
of committee a bill which would set-up the Coastal and Ocean Protection
Council, an advisory body that would review and recommend actions to
improve the health of the State's coastal and ocean environments. In
September, at a special meeting at Monmouth University the Senate Environment
Committee approved a similar bill. With NJEL as a member, the Coastal
Ocean Coalition is advocating for passage of the bills in January. This
is an important first step toward evaluating and mitigating the impacts
that our development and commercial activities have had on this entire
endangered environment, not just on "micro" segments or individual
towns.
****************
NJEL's Spring 2006 and Summer 2007 newsletters explained some of the
concerns and recommendations of the Coastal Ocean Coalition and also
explained the structure of the proposed Council. Those issues of

Contact your legislators and tell them to establish the Coastal
and Ocean Protection Council.

The
Vote For Open Space
-
Ballot Question
3 passed, but the margin was slim: statewide, only 54% of the voters
voted in favor of the bond issue that will provide $200 million for
open space and historic site preservation. There were surprising and
disappointing results in some counties where open space preservation
is particularly urgent to protect biodiversity and drinking water sources.
Included are some counties within the Pinelands and Highlands regions.
A majority of voters in Ocean and Atlantic Counties, both of which include
fragile Pinelands and coasts, voted against Q. 3. Cape May was another
coastal county where more voters said "no" rather than "yes"
to open space funding. In northern New Jersey, slight majorities of
voters in Hunterdon, Morris, Sussex, and Warren Counties rejected the
ballot question. A number of environmental organizations, including
NJEL, conducted voter education campaigns with printed material, emails,
and telephone calls. Responses from some individuals contacted by NJEL,
even those who consider themselves environmentalists, indicated that
voters are very concerned about State spending and property taxes. Others
lack confidence in the decision-making processes for selecting and negotiating
property acquisitions. Although data show that open space generally
keeps municipal costs down, apparently there are many voters who are
unconvinced of the urgency to preserve open space and historic sites.
It has been demonstrated repeatedly that large residential developments
cost more in education and municipal services than the tax revenue that
they generate. In particular, when a town's excess capacity in schools,
water and sewer systems, and fire and police services is absorbed by
new residents, the fixed costs of additional infrastructure and the
next unit of operating costs (e.g., the additional teacher, the additional
police officer the additional trash collector) increase the average
cost per household. Is it just a New Jersey experience, a function of
our density and high costs? Apparently not. Towns in other states have
similar experiences. NJEL member Melanie Hobart was a member of a team
that analyzed one year of municipal costs for Williamstown, MA, a rural
community of 8,500 in the Berkshires, home of Williams College. For
every $1 in revenue generated by a property category, the average costs
to the town were 25 cents for open space, 42 cents for industrial/commercial,
and a whopping $1.115 for residential.
