What
are Greenhouse Gas Emissions?
Greenhouse
Gas Emissions are those greenhouse gases that allow sunlight to enter the
atmosphere freely and contribute to the greenhouse effect, which many believe
is the cause of global warming. There are natural and man-made greenhouse gas
emissions. The primary greenhouse gases thought to be major contributors
to global warming are; carbon dioxide emissions (CO2), methane emissions (CH 4) and
nitrogen oxides (N2O).
The
primary sources of greenhouse gas emissions from manmade sources include;
fossil-fueled power plants such as natural gas power plants and coal fired
power plants. Other sources of greenhouse gas emissions linked to manmade
causes include internal combustion engines (fueled by gasoline and
petroleum diesel) and deforestation.
Many
people don't realize that as much as 25% of per cent of the carbon dioxide emissions are
naturally absorbed by the ocean and another 25% of the carbon dioxide
emissions are absorbed by our biosphere, such as trees, plants, soil,
etc. This leaves about 50% of the carbon dioxide emissions that are not
absorbed and remaining in our atmosphere. As previously stated, carbon dioxide emissions
are linked primarily to the burning of fossil fuels (power plants, cars,
trucks, etc.) and deforestation.
Greenhouse
gas emissions have been on the increase ever since the dawn of the industrial
revolution.
What
Are Greenhouse Gases?
Many chemical compounds found in the Earth’s atmosphere act as “greenhouse
gases.” These gases allow sunlight to enter the atmosphere freely. When
sunlight strikes the Earth’s surface, some of it is reflected back towards
space as infrared radiation (heat). Greenhouse gases absorb this infrared
radiation and trap the heat in the atmosphere. Over time, the amount of energy
sent from the sun to the Earth’s surface should be about the same as the
amount of energy radiated back into space, leaving the temperature of the
Earth’s surface roughly constant.
Many
gases exhibit these “greenhouse” properties. Some of them occur in nature
(water vapor, carbon dioxide, methane, and nitrous oxide), while others are
exclusively human-made (like gases used for aerosols).
How
Can We Decrease Greenhouse Gas Emissions?
Cogeneration, for industrial
customers, and trigeneration, for
commercial applications, are the most efficient ways of producing energy for
these applications. Cogeneration, at
around 60-70% efficiency, is more than twice the efficiency of traditional power
plants. Cogeneration is the
simultaneous production of electrical and thermal energy, and is the best method
of generating electricity and steam for industrial customers such as refineries,
plastics, and paper/wood industries. Trigeneration,
at about 90% efficiency, is about 300% more efficient over traditional electric
power plants. Trigeneration is the
simultaneous production of cooling, heating and power, and the best method for
generating power and energy for commercial customers like office buildings,
schools, universities, military bases, shopping centers, radio/television
stations, and casinos, among many other commercial applications.
Why
Are Atmospheric Levels Increasing?
Levels
of several important greenhouse gases have increased by about 25 percent since
large-scale industrialization began around 150 years ago (Figure 1). During the
past 20 years, about three-quarters of human-made carbon
dioxide emissions were from burning fossil fuels.
Figure
1. Trends in Atmospheric Concentrations and Anthropogenic Emissions of Carbon
Dioxide

Concentrations of carbon dioxide in the atmosphere are naturally regulated by
numerous processes collectively known as the “carbon cycle” (Figure 2). The
movement (“flux”) of carbon between the atmosphere and the land and oceans
is dominated by natural processes, such as plant photosynthesis. While these
natural processes can absorb some of the net 6.1 billion metric tons of
anthropogenic carbon dioxide emissions produced each year (measured in carbon
equivalent terms), an estimated 3.2 billion metric tons is added to the
atmosphere annually. The Earth’s positive imbalance between emissions and
absorption results in the continuing growth in greenhouse gases in the
atmosphere.
Figure
2. Global Carbon Cycle (Billion Metric Tons Carbon)

What
Effect Do Greenhouse Gases Have on Climate Change?
Given
the natural variability of the Earth’s climate, it is difficult to determine
the extent of change that humans cause. In computer-based models, rising
concentrations of greenhouse gases generally produce an increase in the average
temperature of the Earth. Rising temperatures may, in turn, produce changes in
weather, sea levels, and land use patterns, commonly referred to as “climate
change.”
Assessments
generally suggest that the Earth’s climate has warmed over the past century
and that human activity affecting the atmosphere is likely an important driving
factor. A National Research Council study dated May 2001 stated, “Greenhouse
gases are accumulating in Earth’s atmosphere as a result of human activities,
causing surface air temperatures and sub-surface ocean temperatures to rise.
Temperatures are, in fact, rising. The changes observed over the last several
decades are likely mostly due to human activities, but we cannot rule out that
some significant part of these changes is also a reflection of natural
variability.”
However,
there is uncertainty in how the climate system varies naturally and reacts to
emissions of greenhouse gases. Making progress in reducing uncertainties in
projections of future climate will require better awareness and understanding of
the buildup of greenhouse gases in the atmosphere and the behavior of the
climate system.
What Are the Sources of Greenhouse Gases?
In
the U.S., our greenhouse gas emissions come mostly from energy use. These are
driven largely by economic growth, fuel used for electricity generation, and
weather patterns affecting heating and cooling needs. Energy-related carbon
dioxide emissions, resulting from petroleum and natural gas, represent 82
percent of total U.S. human-made greenhouse gas emissions (Figure 3). The
connection between energy use and carbon dioxide emissions is explored in the
box on the reverse side (Figure 4).
Figure 3. U.S. Anthropogenic Greenhouse Gas Emissions by Gas, 2001
(Million Metric Tons of Carbon Equivalent)

Figure
4. U.S. Primary Energy Consumption and Carbon Dioxide Emissions, 2001

Another
greenhouse gas, methane, comes from landfills, coal mines, oil and gas
operations, and agriculture; it represents 9 percent of total emissions. Nitrogen
oxides (5 percent of total emissions), meanwhile, is emitted from burning
fossil fuels and through the use of certain fertilizers and industrial
processes. Human-made gases (2 percent of total emissions) are released as
byproducts of industrial processes and through leakage.
What
Is the Prospect for Future Emissions?
World
carbon dioxide emissions are expected to increase by 1.9 percent annually
between 2001 and 2025 (Figure 5). Much of the increase in these emissions is
expected to occur in the developing world where emerging economies, such as
China and India, fuel economic development with fossil energy. Developing
countries’ emissions are expected to grow above the world average at 2.7
percent annually between 2001 and 2025; and surpass emissions of industrialized
countries near 2018.
Figure
5. World Carbon Dioxide Emissions by Region, 2001-2025
(Million Metric Tons of Carbon Equivalent)

The
U.S. produces about 25 percent of global carbon dioxide emissions from burning
fossil fuels; primarily because our economy is the largest in the world and we
meet 85 percent of our energy needs through burning fossil fuels. The U.S. is
projected to lower its carbon intensity by 25 percent from 2001 to 2025, and
remain below the world average (Figure 6).

Energy
Production and Carbon Dioxide
Emissions
For over one hundred years, energy and power production have been generated
around the world through the burning of fossil fuels, including; fuel oil,
coal, diesel, and natural gas. Over the past decade, environmental science
and research has discovered and linked global warming, and global climate change
to the carbon dioxide emissions
from the combustion of fossil fuels. This has placed an increased need to
reduce energy consumption and discover more environmentally friendly fuel
sources.
A Cogeneration powerplant produces
heat and power simultaneously by burning a primary fuel like natural gas, or biomethane.
Cogeneration plants typically reach
system efficiencies of 60% to 70% - or about double that of standard power
plants. Trigeneration plants
produce 3 energies - cooling, heating and power - simultaneously, with one fuel input and combustion process (such as natural
gas or biomethane) and is an
environmentally-friendlier method of generating electricity. Trigeneration, at around 90% efficiency, is about 300% more
efficient than typical power plants, and 50% more efficient than cogeneration
plants. Cogeneration and trigeneration
power plants are much less expensive and costly in terms of both economic and
environmental expenses, than traditional forms of power generation. There
are also far fewer carbon and carbon
dioxide emissions generated through co/trigeneration.
Trigeneration
slashes carbon dioxide emissions
by as much 80% and more.
In 1992, managers of the 2.8-million-square-foot McCormick Place Exhibition and
Convention Center in Chicago were planning an addition that would double the
size of their convention center. To avoid $27 million in capital costs for a new
heating and cooling system, the McCormick Place managers selected a new trigeneration
system under an energy outsource or energy services agreement. The new trigeneration
system simultaneously provides the McCormick Place Convention Center with
heating, cooling, and electricity and achieves an overall efficiency rating of
93%. Besides the initial savings of not having to spend $27 million for
the new system, McCormick Place also saves >$1 million annually in energy and
operating expenses. The system produces about half the carbon dioxide emissions
of a traditional system, as well as 24,000 tons of carbon dioxide and 59 tons of
nitrogen oxides (NOx) each year when
compared to a traditional system.
Coors
Brewing Company has a 90 percent efficient trigeneration
system at its Golden, Colorado plant, the largest single brewing site in the
world. The trigeneration system saves
250,000 tons of carbon dioxide annually, along with 125 tons of NOx and 900 tons
of SO2.
*
A New Perspective on Energy
Integrated
systems for cooling, heating and power (CHP) for buildings incorporate multiple
technologies for providing energy services to a single building or to a campus
of buildings. Electricity to such buildings is provided by on-site or near-site
power generators using one or more of the many options: internal combustion (IC)
engines, combustion turbines, miniturbines or microturbines, and fuel cells. In CHP
systems, waste heat from
power generation equipment is recovered for operating equipment for cooling,
heating, or controlling humidity in buildings, by using absorption chillers,
desiccant dehumidifiers, or heat recovery equipment for producing steam or hot
water. These integrated systems are known by a variety of acronyms: CHP,
Trigeneration and IES (Integrated
Energy System).
CHP systems provide many benefits, including:
reduced energy costs,
improved power reliability,
increased energy efficiency, and
improved environmental quality.
What is a CHP System?
A
CHP System is an efficient, environmentally-friendly "cogeneration"
system that provides power (electricity) and energy (hot water and/or steam) at
the location the power and energy are needed also known as "distributed
generation." Cogeneration systems are at least two times more efficient
than typical power plants which average about 27% - 35% efficiency - meaning 65%
to 73% of the energy is wasted.
What
is a CHP System with Absorption Chillers or "Trigeneration"?
Even
more efficient than a standard CHP system is a CHP system that incorporates
absorption chillers, which is then a "trigeneration" system,
also referred to as an "Integrated Energy System" or "Cooling,
Heating and Power." Trigeneration systems can be up to 50% more
efficient than cogeneration systems and many average about 90% or more
efficiency. Absorption chillers recover the additional waste heat from CHP
Systems to make chilled water for air-conditioning, thereby providing the
building or facility's electricity, hot water/steam and air conditioning.

Energy Production and Carbon Dioxide Emissions
For over one hundred years, energy and power production have been
generated around the world through the burning of fossil fuels,
including; fuel oil, coal, diesel, and natural gas. Over the
past decade, environmental science and research has discovered and linked global
warming, and global climate change to the carbon dioxide emissions from
the combustion of fossil fuels. This has placed an increased need to reduce energy consumption and discover more environmentally friendly fuel sources.
Co/trigeneration is the simultaneous production of electricity and thermal energy at the same time,
with one fuel input and combustion process (such as natural gas) and is an
environmentally-friendlier method of generating electricity.
Co/trigeneration is much less expensive and costly in terms of both
economic and environmental expenses, than traditional forms of power
generation. There are also far fewer carbon and carbon dioxide
emissions generated through co/trigeneration.
Co/trigeneration slashes carbon dioxide emissions by as much
80% and more.
In 1992, managers of the 2.8-million-square-foot McCormick Place Exhibition and Convention Center in Chicago were planning an addition that would
double the size of their convention center. To avoid $27 million in capital costs for
a new heating and cooling system, the McCormick Place managers selected Trigen Energy Corporation of White Plains, New
York to install a new trigeneration system under an energy outsource or
energy services agreement. Trigen installed the new trigeneration system that simultaneously provides
the McCormick Place Convention Center with heating, cooling, and
electricity and achieves an overall efficiency rating of 93%. Besides the
initial savings of not having to spend $27 million for the new system, McCormick Place also
saves >$1 million annually in energy and operating expenses. The system produces about half the carbon dioxide emissions of a

Carbon Dioxide Emissions from the
Generation of Electric Power in
the United States
July 2000
Introduction
The President issued a directive on April 15, 1999, requiring an annual
report summarizing the carbon dioxide (CO2) emissions produced
by the generation of electricity by utilities and nonutilities in the
United States. In response, the U.S. Department of Energy (DOE) and the
U.S. Environmental Protection Agency (EPA) jointly submitted the first
report on October 15, 1999. This is the second annual report(1)
that estimates the CO2 emissions attributable to the generation
of electricity in the United States. The data on CO2 emissions
and the generation of electricity were collected and prepared by the
Energy Information Administration (EIA), and the report was jointly
written by DOE and EPA to address the five areas outlined in the
Presidential Directive.
-
The emissions of CO2 are presented on the basis of total
mass (tons) and output rate (pounds per kilowatthour). The information
is stratified by the type of fuel used for electricity generation and
presented for both regional and national levels. The percentage of
electricity generation produced by each fuel type or energy resource
is indicated.
-
The 1999 data on CO2 emissions and generation by fuel
type are compared to the same data for the previous year, 1998.
Factors contributing to regional and national level changes in the
amount and average output rate of CO2 are identified and
discussed.
-
The Energy Information Administration's most recent projections of
CO2 emissions and generation by fuel type for 1999 are
compared to the actual data summarized in this report to identify
deviations between projected and actual CO2 emissions and
electricity generation.
-
Information for 1998 on voluntary carbon-reducing and
carbon-sequestration projects reported by the electric power sector
and the resulting amount of CO2 reductions are presented.
Included are programs undertaken by the utilities themselves as well
as programs supported by the Federal government to support voluntary
CO2 reductions.
-
Appropriate updates to the Department of Energy's estimated
environmental effects of the Administration's proposed restructuring
legislation are included.
Electric Power Industry CO2 Emissions and
Generation Share by Fuel Type
In 1999,(2) estimated emissions of CO2
in the United States resulting from the generation of electric power were
2,245 million metric tons,(3) an increase
of 1.4 percent from the 2,215 million metric tons in 1998. The estimated
generation of electricity from all sources increased by 2.0 percent, going
from 3,617 billion kilowatthours to 3,691 billion kilowatthours.
Electricity generation from coal-fired plants, the primary source of CO2
emissions from electricity generation, was nearly the same in 1999 as in
1998. Much of the increase in electricity generation was produced by
gas-fired plants and nuclear plants. The 1999 national average output
rate,(4) 1.341 pounds of CO2 per
kilowatthour generated, also showed a slight change from 1.350 pounds CO2
per kilowatthour in 1998 (Table 1). While the share of total generation
provided by fossil fuels rose slightly, a reduction in the emission rate
for coal-fired generation combined with growth in the market share of
gas-fired generation contributed to the modest improvement in the output
rate.(5)

In the United States, about 40.5 percent(6)
of anthropogenic CO2 emissions was attributed to the combustion
of fossil fuels for the generation of electricity in 1998, the latest year
for which all data are available.(7) The
available energy sources used for electricity generation result in varying
output rates for CO2 emissions from region to region across the
United States. Although all regions use some fossil fuels for electricity
generation, several States generate almost all electricity at nuclear or
hydroelectric plants, resulting in correspondingly low output rates of CO2
per kilowatthour. For example, Vermont produces mostly nuclear power,
while Washington, Idaho, and Oregon generate almost all electricity at
hydroelectric plants. At the other extreme, Colorado, Indiana, Iowa,
Kentucky, New Mexico, North Dakota, Ohio, West Virginia, and Wyoming--a
group that includes some of the Nation's largest coal-producing
States--generate most of their electricity with coal. Regions where
coal-fired generators dominate the industry show the highest rates of CO2
emissions per kilowatthour.
Coal
Estimated emissions of CO2 produced by coal-fired generation
of electricity were 1,788 million metric tons in 1999 (Table 1), 0.7
percent less than in 1998, while electricity generation from coal was 0.4
percent more than the previous year. The divergent direction of generation
and emissions changes may reflect a combination of thermal efficiency
improvements, changes in average fuel characteristics, and variances
associated with both sampling and nonsampling errors. CO2
emissions from coal-fired electricity generation comprise nearly 80
percent of the total CO2 emissions produced by the generation
of electricity in the United States, while the share of electricity
generation from coal was 51.0 percent in 1999 (Table 3). Coal has the
highest carbon intensity among fossil fuels, resulting in coal-fired
plants having the highest output rate of CO2 per kilowatthour.
The national average output rate for coal-fired electricity generation was
2.095 pounds CO2 per kilowatthour in 1999 (Table 4).
Coal-fired generation contributes over 90 percent of CO2
emissions in the East North Central, West North Central, East South
Central, and Mountain Census Divisions and 84 percent in the South
Atlantic Census Division (Table 2). Nearly two-thirds of the Nation's CO2
emissions from electricity generation are accounted for by the combustion
of coal for electricity generation in these five regions where most of the
Nation's coal-producing States are located. Consequently, these regions
have relatively high output rates of CO2 per kilowatthour.
