Kyoto Protocol and Energy Issues
Problems/Case Studies
"Watch
Your
Step: Understanding the Impact of Your Personal Consumption on
the Environment", Philip
Camill,
Carleton
College. State University of New York at Buffalo’s National
Center for Case Study Teaching
This case makes use of the
concept of the "ecological footprint," developed by Wackernagel
and colleagues to quantify the amount of land area required to
sustain the lifestyle of a population of any size. Students
calculate their consumption of energy and materials to determine
their personal ecological footprint and in the process learn about
concepts of sustainability, ecological efficiency, and energy flow
up food chains as well as the moral and ethical dimensions of how
our lifestyles impact the Earth. The case includes an Excel
spreadsheet for students to track their personal consumption of
resources. Developed for an introductory biology course, the case
could also be used in upper level courses such as ecology,
conservation biology, evolution, diversity, and the biology of
social issues, or in a non-majors biology course.

"Kyoto
Protocol (George W. Bush)": Environmental Science 5th Ed. CNN Ed
(2:18)
President George W. Bush—in an
attempt to reduce greenhouse gas emissions and meet emission
reduction standards set by the Kyoto Protocol—created a new policy
that will offer tax incentives to businesses and industries in
exchange for reducing nearly 500 metric tons of carbon dioxide
(CO2) emissions by 2012. According to White House officials,
meeting the reduction standards for CO2 emissions, originally
proposed by the Kyoto treaty, would cost the U.S. 400 billion
dollars and would leave 5 million Americans jobless. White
House officials believe that the new policy is an excellent step
in the attempt to reduce greenhouse gas emissions such as nitrogen
oxide (NOx), sulfur dioxide (SO2), and mercury. However,
Democratic Party officials believe it is a step in the wrong
direction, stating that the Bush administration's plan is only
slowing the growth of greenhouse gas emissions rather than
reducing the gas emissions altogether. The worksheet

Climate Change web site. (Student worksheet provided on CD)
"Kyoto Protocol
(1997 U.N.)": Environmental Science 7th Ed. CNN Ed (2:14)
In 1997, the United Nations
established the Kyoto protocol in an attempt to drastically reduce
greenhouse gas emissions by the year 2012. The primary reductions
include emissions from carbon dioxide (CO2), nitrogen oxides (NOx)
and methane. Initially, many nations were in favor of the Kyoto
protocol, but in 2001, the Bush administration terminated U.S.
participation and cited many concerns that participation could
weaken the U.S. economy. Instead, the Bush Administration proposed
that the U.S. and other countries focus on conducting more
research on global warming and improving technology to reduce
emissions. In the same respect, Russian officials are concerned
that their participation could slow Russian economic growth, while
other emerging countries grow without limits on their greenhouse
gas emissions. (Student worksheet provided on CD)
"Global
Environment Outlook": Environmental Science 6th Ed. CNN Ed (2:37
min)
According to the United Nations
Environment Program Global Environment Outlook 3 (GEO-3), the
world is at a crossroad between a future of health and prosperity,
or widespread environmental disaster. Over 1,000 researchers
and scientists contributed to the report, which reviews climate
changes over the past 30 years and makes predictions for
environmental changes during the next 30 years. Over the
next three decades, scientists predict that the world may begin to
experience the effects of greenhouse gas pollution, as the global
climate changes and as Earth experiences increases in hurricanes,
floods, and droughts. Furthermore, the quality of human life
may significantly lower as nearly 25% of the world’s mammals face
the possibility of extinction; countries face severe poverty,
diseases, and shortages in clean drinking water; and 70% of
Earth’s land surface is consumed by cities, industries, mining,
and agriculture. (Student worksheet provided on CD)
"Solar Energy":
Environmental Science 7th Ed. CNN Ed (2:38)
Over the past few decades,
improved technology and government tax incentives have contributed
to the growing use of a renewable energy source known as solar
energy. Solar power currently accounts for nearly 1% of the total
energy used throughout the world. Compared to traditional fossil
fuel energy sources, solar energy has higher costs, but has no
pollution output and can be easily integrated into residential
housing. The typical home application of solar energy requires a
cost of at least $25,000, which is nearly 2 ½ times the
price of traditional electricity. The worksheet includes the URL
for the U.S. Department of Energy website. (Student

"California
Energy Crisis": Environmental Science 6th Ed. CNN Ed (2:01 min)
In a world where we are at the
dawn of a new millennium, the one constant obstacle to
technological progress is a limited supply of energy to power our
industries. The power generation industry is a business
currently undergoing a dramatic amount of change, primarily
because of two reasons: deregulation and growing demand for
electricity. Due to unexpected demand by consumers and the
decrease in output capacity, brown outs and black outs have become
more frequent during times of peak demand. After the
California energy crisis of 2000 and 2001, many news and industry
analysts believe that there may not be enough power generation
capacity to meet future demands. As our world continues to
grow, we need to learn new methods of fueling our limitless power
needs without destroying our environment. The worksheet

website. (Student worksheet provided on CD)
"Algal Fuel":
Biology 6th Ed. CNN Ed 2002 (2:00)
University of California, Berkeley
professor Tasios Melis has discovered an way to use “pond scum” to
generate hydrogen gas. He found that when algae are deprived of
sulfur, they turn to a metabolic pathway the produces hydrogen
gas. Melis explains that hydrogen gas is a more efficient and
cleaner burning fuel than any alternatives. His goal is to
maximize the efficiency of the algal fuel production process.

"Nuclear
Fallout": Environmental Science 7th Ed. CNN Ed (2:01)
One of the side effects of the
detonation of a nuclear bomb on or near Earth’s surface is
radiation exposure. During the 1950s, the U.S. government
conducted many nuclear tests as part of research, but at the time,
federal officials were unaware of the dangers of radioactive
fallout. According to the U.S. Department of Health and Human
Services, nuclear explosions may have inadvertently caused at
least 15,000 deaths due to radiation exposure. Furthermore,
radiation from nuclear tests has spread to areas throughout the
U.S., from California, Washington, and Oregon to Vermont, New
Hampshire, and North Carolina. The worksheet includes the URL for
the Office of Nuclear Energy. (Student worksheet provided on
CD)
"Renewable
energy": Environmental Science 5th Ed. CNN Ed 2002 (2:10)
President Jimmy Carter, in an
address to the nation, proposed that by the end of the century,
20% of the electricity used in the U.S. should be derived from the
sun. At the time he made the statement, it seemed like an
environmentally friendly vision that could be accomplished;
however, as we enter the year 2002, solar and wind generated power
only supply about 2% of the nation’s demand for electricity.
In the past, the barrier that separated wind and solar energy from
fossil fuel energy was cost efficiency. Recently, many
advances in technology may have broken that cost barrier, and it
may no longer be an obstacle for industry and consumers to have
cheaper access to renewable energy. Some officials comment
that the prices of renewable energy are about 1/8 of what they
were 12 years ago, and they expect solar and wind powered energy
to be the fastest growing energy source for individual buildings
and houses over the next few decades. In fact, in some
areas, wind farms are growing in demand because they are cheaper
to add than non-renewable fossil fuel energy sources. Some
energy analysts are optimistic that by the year 2020, wind and
solar energy may supply 10% of the nation’s energy demands.
Other renewable energy sources such as hydroelectric dams, which
currently generate about 8–10% of the nations electricity, are not
expected to grow in demand. Although hydroelectricity is
viewed as a clean energy source, it does come at a high price of
altering the natural flow of river water, nearby plant and
wildlife habitats, and forcing some fish species near
extinction. The worksheet includes the URL for the U.S.
Department of Energy web site.
"Chernobyl":
Environmental
Science 5th Ed. CNN Ed 2002 (2:56)
On 26 April 1986, one of the
world’s largest nuclear accidents took place in Chernobyl,
Ukraine. The accident began at the Chernobyl power plant in
reactor number four resulting from a safety test failure.
After the safety test failure, the reactor went through a series
of explosions that eventually led to a nuclear meltdown that
spread radiation throughout the Ukraine, Belarus, and parts of
Russia. The official death toll from the accident was at
least 32; however, some experts believe that the immediate
explosion may not be responsible for numerous deaths.
Instead, they believe that the after effects of radiation may be
responsible for many thousands of cases of thyroid cancer and many
other radiation-related illnesses that still occur. In
nearby Poland, citizens were given potassium iodide (known as KI)
within hours of the nuclear meltdown, and residents in that area
did not have the high rates of thyroid cancer that other areas
experienced. This is because KI has been proven to prevent
thyroid cancer only if it is taken within 3–4 hours after a
radiation release. Similarly, on 28 March 1979, another
nuclear meltdown occurred on the Three Mile Island nuclear station
near Harrisburg, Pennsylvania. Nearly 237,000 KI pills were
organized by the federal government; however, the pills were
useless since the public didn’t receive the pills until six days
after the accident. After the recent events, federal
representatives such as Hillary Rodham Clinton are working toward
having stockpiles of KI pills ready for residents who live within
a 50 mile radius of any nuclear facility in the U.S. The
Nuclear Regulatory Commission Chairman Richard Meserve believes
that having stockpiles of KI would be a bad idea because it gives
the public a false hope that they are protected against
radiation. In fact, KI only protects against thyroid cancer
and not against other problems associated with radiation
exposure. The worksheet includes the URL for the CNN web
site.
"Nuclear power
plant safety": Environmental Science 5th Ed. CNN Ed 2002 (2:03)
After the events of September
11th, the safety and security of the nation’s nuclear power
facilities has come into question by federal officials and the
public. Many residents who live near nuclear power
facilities are carrying potassium iodide or KI pills to prevent
thyroid cancer, which can result from exposure to radiation.
Residents who live near New York’s Indian Point nuclear power
plant keep KI pills ready for themselves and families should the
unthinkable happen. Officials at Indian Point comment that
although the facility was not originally designed to withstand the
impact of an airplane, that shouldn’t discourage nearby
residents. The containment buildings are protected by 3 1/2
feet of cement with 8 rows of interwoven reinforced steel, and
officials believe that if a plane was to attempt to fly into the
facility, it would most likely bounce off the containment
walls. Even though Indian Point officials believe there is
no danger at stake, some residents still believe that any nuclear
plant in a densely populated area and near five major airports
should be shut down for safety precautions.
"Ethanol fueled
vehicles": Environmental Science 5th Ed. CNN Ed 2002 (2:18)
On 15 March 2002, California
Governor Gray Davis issued an executive order to phase out Methyl
Tertiary Butyl Ether (MTBE) to ethanol in California vehicle
gasoline. In addition, the order called for refineries to
complete the transition from MTBE to ethanol by 31 December
2003. The reason for the sudden change in gasoline additives
is the discovery that MTBE pollutes groundwater. The news of
the sudden change was a windfall for Midwestern corn farmers,
since ethanol is derived from corn. Some farmers believe
that the nationwide farm income could be increased by nearly 1
billion dollars due to the higher demand for ethanol. For
California drivers, the news is not as pleasant. It is
estimated that the use of ethanol may add 4–5 cents per gallon to
California gas; however, if refineries have trouble supplying
ethanol to consumers, then the cost of gas could be raised by 50
cents per gallon or more. Some officials are concerned that
although ethanol produces less air pollution, ethanol does not
have a long shelf life, must be shipped separately from gasoline,
and must then be added in at the last minute before it reaches the
consumer. California has the strictest air pollution
standards in the U.S. However, some experts believe that the
addition of ethanol to gas is unnecessary, and an increase in
fuel-efficient vehicles would make up for the difference of adding
ethanol to gasoline. The worksheet includes the URL for the
California Energy Commission web site.
"Clean power
act": Environmental Science 5th Ed. CNN Ed 2002 (2:14)
As a part of the latest efforts to
curb greenhouse gases and global warming, Senator James Jeffords
of Vermont put together the Clean Power Act of 2001. The act
proposed that all fossil fuel burning power plants cut their
mercury emissions by 90%, sulfur dioxide (SO2) by 87% (from 1999
levels), nitrogen oxide (NOx) by 75% (from 1997 levels), and
carbon dioxide (CO2) to 1990 levels. In addition, the bill
requires that all obsolete power plants update their equipment to
standards by the 30th year of operation of the plant or by the 5th
year after the bill has become law. Power plant officials
estimate that the updates to the plants may cost nearly 3 billion
dollars and contend that the price of electricity may be raised in
the interim to compensate for the losses. New York officials
comment that the benefits outweigh the costs, considering that air
pollution in New York costs almost 60 billion dollars. Some
lawmakers believe that the bill’s chances of becoming a law are
remote; however, it has made lawmakers aware of the problems of
pollution.
