Objectives Describe how natural gas may help
improve public health Describe the benefits natural gas offers
to the environment Explain how natural gas may help
stimulate the economy Describe what energy security is and
how using natural gas can help attain it Explain the future of natural gas Explain the suggested actions to support
natural gas
3
Fewer emissions than conventional fuels
Established distribution network Pipeline and trucks used for transport
Produced domestically Often less expensive than gasoline
Why Consider Natural Gas?
4
Advantages of Natural Gas Both CNG and LNG available through
established distribution networks Most natural gas produced
domestically CNG often costs less than gasoline
where available Natural gas vehicle engines often last
longer and require less frequent service than conventional vehicles

6
Additional Points to Consider 112,000 natural gas vehicles on U.S.
roads 13 million worldwide Just over 1,000 natural gas vehicle
fueling stations in the U.S. – obstacle to overcome
Natural gas has a lower energy density when compared to conventional gasoline
NGV purchase price tends to be higher than conventional vehicles
7
There are many benefits of using natural gas to fuel vehicles: Betterment of health and
environment Benefits to the U.S. economy National energy security Reduce dependence on foreign oil
Natural Gas Benefits
8
Nontoxic Significantly lower amounts of
harmful emissions such as: Oxides of nitrogen (NOx) Particulate matter Carbon Monoxide (CO)
Fewer health concerns through reduced emissions Asthma, emphysema, bronchitis all linked
to smog
Health Benefits
9
Cleanest of all hydrocarbon fuels Natural gas vehicles may reduce
carbon dioxide (CO2) emissions by 25%, oxides of nitrogen(NOx) emissions by 17% to 80%
Other fossil fuels associated with global warming, smog, and acid rain Natural gas produces fewer emissions
that contribute to these events
Environmental Benefits
10
Compared to traditional diesel vehicles, NGVs have reductions in carbon monoxide (CO) emissions of 75-95%, reductions in carbon dioxide (CO2) emissions of 25%, and nitrogen oxide (NOx) emissions can be reduced by 17-80%.

Did You Know?
11
Most natural gas in the U.S. is produced domestically
Natural gas generally costs less than gasoline Gasoline = average $3.37 per gallon Natural gas = $2.13 per gallon equivalent
Natural gas industry supports U.S. job market, supplying 622,000 jobs in 2008 – expected to add 2.2 million jobs
Economic Benefits
12
87% of the natural gas used in the U.S. is produced domestically
Could alleviate dependence on foreign oil to meet transportation demand
Natural gas production is expected to increase 2.2 trillion cubic feet (tcf) in 2008 12.2 trillion cubic feet (tcf) in 2035
Biogas – domestic source of renewable natural gas
Energy Security Benefits
13
Did You Know?
Natural gas is primarily a domestic energy source. In 2010, 87% of the natural gas consumed in the U.S. was produced domestically. The remaining gas supply came from Canada (11%), with 2% imported as liquefied natural gas (LNG).

14
Natural gas is a promising alternative fuel that can lessen dependence on foreign oil Around half of the petroleum used in the U.S. is
imported 87% of natural gas is produced domestically
Currently fuels over 112,000 vehicles in the U.S. Powers more than 13 million vehicles worldwide
Accounts for nearly 25% of the total energy used in the U.S. Residential and commercial usage – 34% Industrial usage – 27% Electric power production – 31% Vehicle fuel – <1%
Natural Gas – Today and Tomorrow

The Future of Natural Gas Natural gas is a critical element in
energy strategy for the U.S. Advances in exploration and
production technologies have led to new sources of natural gas in U.S. Combined application of horizontal
drilling and hydraulic fracturing techniques that have made the country's vast shale gas resources accessible
Helps reduce dependence on foreign oil Promotes job growth

19
Natural gas for vehicle use nearly doubled between 2003 and 2009
In 2010, natural gas displaced more than 350 million gasoline gallon equivalents (GGE)
Transit buses now account for around 62% of all vehicular natural gas use
In 2009, around 18% of transit buses ran on natural gas Figure 5: Transit bus fleets throughout the
country have made the shift to natural gas. Source: NAFTC.
20
Suggested Actions The federal government, state governments
and even regional and local governments have implemented incentives to encourage the purchase and use of NGVs Incentives include tax deductions/credits,
reduced license fees, reduced vehicle sale taxes, and lower registration fees
Some states also permit certain alternative fuel vehicles to operate in high occupancy vehicle (HOV) lanes during peak rush-hour periods
Individuals encouraged to use public transportation systems that support the growth and use of natural gas in these systems

Upon completing this material, can you: Describe how natural gas may help
improve public health? Describe the benefits to the environment? Explain how natural gas may help
stimulate the economy? Describe what energy security is and how
using natural gas can help attain it? Explain the future of natural gas? Explain the suggested actions to support
natural gas?

1. Give an example of a natural gas vehicle that is successfully reducing carbon emissions.
2. True or False: An extensive natural gas pipeline and distribution network already exists.
3. What is one of the biggest challenges for encouraging the use of NGVs and their increasing demand?
4. True or False: There are many tax incentives for alternative fuel vehicles, but none for CNG.
