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.

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

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.
