# WELCOME!

Welcome to the July 2011 issue of the Clean Cities Alternative Fu el Price Report, a quarterly report designed to keep you up to date

on the prices of alternative fuels and conventional fuels in the U.S. This issue summarizes prices that were collected between

July 14, 2011 and July 29, 2011 from Clean Cities Coordinators, fuel providers, and other Clean Cities stakeholders.



# METHODOLOGY

In order to collect price information for both

alternative fuels and conv entional fuels from areas

across the country, Clean Ci ties Coordinators, fuel

providers, and other key stakeholders were

contacted to request that they provide prices for

fuels in their area on a voluntary basis. Prices were

collected on all major alternative fuels currently in

widespread use (natural gas, propane, biodiesel,

and ethanol), as well as prices for conventional

fuels at stations that also sell alternative fuels (or

stations nearby). Prices were collected from public

and private refueling stations throughout the

country, and were collected between July 14, 2011

and July 29, 2011. Prices were then averaged in

order to determine regional price trends by fuel

and variability in fuel price within regions (and

among regions). Prices in this report are grouped

by U.S. areas as defined by the Petroleum

Administration for Defens e Districts (PADD): the

districts are illustrated in the map to the right.

The prices collected for this report represent retail,

at-the-pump sales prices for each fuel, including federal and state motor fuel taxes. In some cas es, prices were collected from

government or utility refueling facilities and these taxes were not included in the reported price. In these instances, althoug h these

users are not required to pay these taxes, the taxes were added to the reported price to provide a more representative basis fo r

comparison of fuel prices for th e purpose of this report. In some cases, states may charge a flat annual fee for motor fuel tax es

(especially for gaseous fuels like compressed natural gas): these fe es are not considered in the prices reported in these pages

.

# SUMMARY OF CURRENT REPORT INFORMATION

Overall nationwide average prices for

conventional and alternative fuels are shown

in Table 1. 1 

## As this table illustrates,

alternative fuel prices relative to conventional

fuels vary, with some (biodiesel) higher and

some (CNG, E85, and propane) lower. CNG

is about $1.61 less than gasoline on an

energy-equivalent basis, while E85 is about

42 cents less per gallon than gasoline.

Propane is about 59 cents per gallon less than

gasoline. B20 prices are higher than regular

diesel by about 7 cents. B99/B100 blends

have a cost of about 24 cents per gallon more

than regular diesel. 2



## Relative to the last report from April 2011, the average prices fo r most of the fuels included in this price report have decrea sed, by as

much as 13 cents, while the remaining fuel prices increased slightly. It should be no ted that the price increases (or decreases ) could be

attributed both to an actual increase in price and to a slig htly differing sample of prices (both location and quantity).

Prices in this report were co llected and are reported in the

units in which they are typically sold (dollars per gallon or

dollars per gasoline gallon equiva lent). Because of differing

energy contents per gallon for these fuels, the price paid per

unit of energy content can differ somewhat from the price paid

per gallon. Table 2 illustrates the fuel prices from Table 1 for

the current reporting period norm alized to a price per gasoline

gallon equivalent (GGE), per diesel gallon equivalent (DGE),

or per million BTU of energy. This calculation involves the

use of nominal lower heating values in BTU per gallon of fuel

which can be found in the Transportation Energy Data Book. 3



## Note that prices for the alternative fuels in terms of cost per

gallon equivalent are generally higher than their cost per

gallon because of their lowe r energy content per gallon. 4 

## It has

been seen, however, that consumer interest in alternative fuels

increases as the price differentia l per gallon increases, even if

that differential does not directly translate to savings on an

energy-equivalent basis.

1 A very small sample (5 points) of hydrogen information was r eceived: average price for hydrogen was $3.90 per gasoline gallon equivalent in this report.

2 ASTM specifications now include blends of up to 5% biodiesel as regular diesel fuel, therefore the separate listing for B2/B5 has been discontinued from this and subsequent reports.

3 A listing of the conversion factors used appears as an appendix at the end of this report.

4 For ethanol flexible-fuel vehicles, the actual difference in fuel used per mile is somewhat less than would be calculated simp ly on the difference in energy content of the fuels, as some sources

have noted some FFVs can achieve better energy efficiency (miles per unit of energy) on E85 than on gasoline. This effect is no t currently included in these calculations as the magnitude of the

effect varies by vehicle.

# GASOLINE AND DIESEL PRICES

Average prices for gasoline and

diesel as collected by Clean

Cities coordinators and other

stakeholders (supplemented

where necessary with other

reference sources for

conventional fuels) are illustrated

in Table 3. These prices were

collected from re fueling stations

selling both conventional fuels

and alternative fuels, and from

conventional fuel refueling

stations near alternative fuel

stations. There were 456 price

points collected for gasoline and

416 for diesel, with average

prices for gasoline ranging from

a low of $3.50 per gallon in the

Rocky Mountain region to a high

of $3.95 per gallon in the New England region. Diesel prices ranged from $3.84 in the Rocky Mountain region and $4.15 per gallo n

on the West Coast. Because prices for conventional fuels were co llected from stations and region s providing alternative fuel pr ice

information, data collection was not uniform across the regions of the country. The information is, however, representative of

refueling stations selling both alternative fuels and conventional fuels.

Table 4 illustrates average prices as provided by the DOE Energy

Information Administration (EIA) on the petroleum information section of

its website. 5 

## These prices are averages of prices from a selection of 800

retail fuel stations across the country . Note that the average nationwide

price from EIA generally matches relatively closely with the averages from

the station information collected from Clean Cities stakeholders.

Comparisons in this document between conventional fuel prices and

alternative fuel prices will be made using prices collected from Clean Cities

representatives wherever possible, as th ese prices are most representative of

stations selling both conventional and alternative fuels.

# COMPRESSED NATURAL GAS (RELATIVE TO GASOLINE)

Average prices for compressed

natural gas (CNG) for vehicle use

are illustrated in Table 5, grouped

by region. Information on prices

for regular gasoline as provided

by Clean Cities representatives is

also shown. These prices were

collected from across the country

from Clean Cities Coordinators,

fuel providers, and other

stakeholders on a voluntary basis.

Three hundred twenty (320) CNG

prices were collected in this

report. 6



## As Table 5 illustrates by region,

CNG has a lower price than

gasoline for all regions of the

country for which prices were

obtained, with the largest difference ($2.05 per GGE) being in the Rocky Mountain region. On average, CNG costs about $1.61 les s

than gasoline on a per gasoline gallon equivalent basis. Variability of CNG prices was higher (based on a standard deviation an alysis)

than variability of gasoline prices.

The map to the right illustrates some cost

differentials by state for natural gas relative to

gasoline, based on differentials between

natural gas prices and gasoline prices for each

state (versus the regional averages illustrated

in Table 5). In this map, negative numbers

represent costs for natural gas lower than costs

for gasoline. States not highlighted with a

color did not have any natural gas data points

in the current report. As the map illustrates,

CNG prices (per GGE) were favorable relative

to gasoline in most stat es across the country.

6 Prices for CNG were provided by the indi vidual stakeholders in gasoline gallon equivalents from the “price at the pump.” It sh ould be noted that the internal conversion factor between the

physical quantities of gas delivered and gasoline gallon equivale nt was not collected from each of the refueling stations. Regi onal differences in gas heat content relative to the internal pump

conversion factor may change the price per gasoline gallon equivalent: these differences were not determined for this report, h owever.

# COMPRESSED NATURAL GAS (RELATIVE TO DIESEL) 7



## Average prices for compressed

natural gas for vehicle use are

illustrated in Table 6, grouped by

region. Information on prices for

conventional diesel fuel as

provided by representatives from

Clean Cities and supplemental

sources is also shown. These

prices were collected from across

the country from Clean Cities

Coordinators, fuel providers, and

other stakeholders on a voluntary

basis. Note that the CNG prices in

Table 6 are the same group of

prices as for Table 5, but

converted to a cost per diesel

gallon equivalent basis, in order

to compare direc tly with diesel

prices.

As Table 6 illustrates by region, CNG has a lower price than dies el for all regions of the country, with the largest difference ($2.23 per

DGE) being in the Rocky Mountain region. On average, CNG costs about $1.65 less than diesel on a per diesel gallon equivalent

basis. Based on standard deviation calculations, CNG appears to have had more variability in price during this time period rela tive to

diesel fuel.

The map to the right illustrates some cost

differentials by state for natural gas relative to

diesel, based on differentials between natural

gas prices and diesel prices for each state

(versus the regional averages illustrated in

Table 6). In this map, negative numbers

represent costs for natural gas lower than costs

for diesel. States not hi ghlighted with a color

did not have any natural gas data points in the

current report. As with the comparison to

gasoline, natural gas prices relative to diesel

were also favorable for many states, as the

map shows.

7 A total of 11 LNG price points were collected with an average fuel price of $1.85 per gallon.

# ETHANOL (E85) 8



## Average prices for ethanol in an

85% blend with 15% gasoline

(E85) are illustrated in Table 7,

grouped by region. Information

on prices for regular gasoline as

provided by Clean Cities

representatives is also shown.

These prices were collected from

across the country from Clean

Cities Coordinators, fuel

providers, and other stakeholders

on a voluntary basis. A total of

473 prices for ethanol were

collected in this data collection

effort.

Note that E85 has a lower

average price per gallon than

regular gasoline for all regions

(see Table 7). On average, E85 is about 42 cents lower in price than regular gasoline on a per-gallon basis, with the largest a verage

differential (53 cents) being found in the Central Atlantic region . Based on the calculated standard deviations in this set of E85 price

information, it can be seen that price variability for E85 was similar to the price variability for gasoline for the period.

The map to the right illustrates some cost

differentials between E85 and regular gasoline

by state, based on differentials between E85

prices and gasoline prices for each state (versus

the regional averages illustrated in Table 7). In

this map, negative numbers represent costs for

E85 lower than for gasoline, and positive

numbers represent costs for E85 higher than

gasoline. States not highlighted with a color did

not have any E85 data points in the current

report. In the time period for this report, E85

costs less per gallon than gasoline for most areas

for which prices were available: the best pricing

was in the Midwest.

8 Ethanol (E85) contains about 30% less energy (BTUs) per volume than gasoline. FFVs operating on E85 do not experience a loss i n operational performance, bu t may experience a 25-30%

decrease in miles driven per gallon compared to operation on gasoline. For a side-by-side comparison of available vehicles, vis it http://www.fueleconomy.gov

# PROPANE

Average prices for propane are

illustrated in Table 8, grouped by

region. Information on prices for

regular gasoline as provided by

representatives from Clean Cities

is also shown. These prices were

collected from across the country

from Clean Cities Coordinators,

fuel providers, and other

stakeholders on a voluntary basis.

Three hundred sixteen (316)

propane prices were collected in

this reporting period.

As Table 8 illustrates regionally,

propane prices are lower than

gasoline in all regions for this

report. Overall, propane was

about 59 cents per gallon less

than gasoline with the largest average price differential of 85 cents found in the Midwest. Based on calculations of standard d eviation

in prices, it can be seen that propane prices for vehicle use seems to have varied more than gasoline prices during this sampli ng

period. 9



## The map to the right illustrates some cost

differentials between propane and regular

gasoline on a per-gallon basis, based on

differentials between propane prices and

gasoline prices for each state (versus the

regional averages illustrated in Table 8). In this

map, negative numbers represent costs for

propane lower than co sts for gasoline, and

positive numbers represent propane prices

higher than gasoline. States not highlighted

with a color did not have any propane data

points in the current report. Several regions

had states with favorable propane prices (per

gallon) including the Midwest, West Coast,

and both Atlantic regions.

9 Prices for propane in this report are from both private fleet refueling stations and public refueling sites that can provide p ropane for vehicles and for other us es. The prices at private stations

are generally lower, and may be more representative of the prices the majority of propane vehicle users pay.

# BIODIESEL BLENDS: B20

Average prices for biodiesel in a

20% blend with 80% diesel

(B20) are illustrated in Table 9,

grouped by region. Information

on prices for regular diesel as

provided by Clean Cities

representatives is also shown.

These prices were collected from

across the country from Clean

Cities Coordinators, fuel

providers, and other stakeholders

on a voluntary basis. A total of

156 prices were obtained for B20

across the country.

As Table 9 illustrates, biodiesel

in a B20 blend has an average

price per gallon that is somewhat

higher than conventional diesel

fuel in some regions and lower in others (ranging from 17 cents more to 4 cents less per gallon). Based on calculations of stan dard

deviation on B20 prices, regional price va riability for B20 was slightly larger in most areas than that for conventional diesel . On

average in the U.S., biodiesel in a B20 blend costs about 7 cents more per gallon than conventional diesel fuel based on curren t

information.

The map to the right illustrates some cost

differentials between B20 and diesel on a pergallon basis, based on differentials between

biodiesel prices and diesel prices for each state

(versus the regional averages illustrated in

Table 9). In this map, negative numbers

represent costs for B20 lower than costs for

diesel, and positive numbers represent B20

prices higher than diesel. States not

highlighted with a color did not have any B20

data points in the current report. B20 had

favorable pricing (per gallon) in a number of

states located around the country, most notably

in the Gulf Coast region. Table 9. Biodiesel (B20) Average Prices by Region from Clean Cities Sources

# BIODIESEL BLENDS: B100/B99

Average prices for high-level

blends of biodiesel (99% or

100% biodiesel with diesel fuel)

are illustrated in Table 10,

grouped by region. Information

on prices for regular diesel as

provided by Clean Cities

representatives is also shown.

These prices were collected

from across the country from

Clean Cities Coordinators, fuel

providers, and other

stakeholders on a voluntary

basis. A total of 46 price points

were collected from stations

offering B99/B100 for sale

across the country.

As Table 10 illustrates

regionally, the cost of B99/B100 is generally more than the cost of diesel fuel per gallon in the regions for which data were c ollected,

up to $1.00 more than diesel. On average across the nation, B99/B 100 is about 24 cents per gallon higher than regular diesel. B ased on

standard deviation calculations on these price points, it appears th at prices for B99/B100 varied more widely for most areas in this

time period than regular diesel.

The map to the right illustrates some cost

differentials between high-level biodiesel

blends and regular diesel on a per-gallon basis,

based on differentials between biodiesel prices

and diesel prices for each state (versus the

regional averages illustrated in Table 10). In

this map, negative numbers represent costs for

these blends that are lower than costs for

diesel, and positive numbers represent prices

for these blends that are higher than diesel.

States not highlighted with a color did not

have any high-level biodiesel blend data points

in the current report. Where data was available

for this report, prices for B100 (per gallon)

were favorable for a number of states in the

Atlantic, Gulf Cost, Midwest, New England,

and West Coast regions. Table 10. Biodiesel (B99

# COMPARISON OF PRICES BY REGION FOR PUBLIC AND PRIVATE REFUELING STATIONS

Table 12 below summarizes the comparison of prices for all of th e fuels included in this report, separated into averages for st ations

open to the public (public refueling stations) and stations availa ble only to selected fleets or privately-owned stations (priv ate refueling

stations). Private fleet fueling stations can typically negotiate prices lower than retail public stations, if they are willing to commit to

purchasing large quantities of fuel over an extended period of time. However, private fleet pricing can sometimes be higher tha n retail

public stations if there are unusual circumstances (remote loca tions, sites that use very small quantities of fuel, or special contracts

where unique billing & accounting services or fleet service management fees ar e rolled into the price of the fuel).

As with the other prices in this report, all of these averages are prices with state and federal taxes included, using the prot ocols

outlined at the beginning of this document.

# HISTORICAL ALTERNATIVE FUEL PRICES FROM PREVIOUS REPORTS

The graphs on this page illustrate the historical prices

for the alternative fuels included in these reports

(specifically natural gas, propane, ethanol, and

biodiesel) relative to gasoline and diesel. These graphs

include prices collected as part of the current Price

Report activity, which began in September 2005.

Natural gas (in GGE), propane, and ethanol have been

graphed against gasoline prices, while natural gas (in

DGE) and biodiesel have been graphed against diesel

prices.

# ILLUSTRATION OF CONVERSION FACTORS FOR FUELS

The standard lower heating values for fuels from the Tr ansportation Energy Data Book 26 are listed below.

Lower Heating Value

Gasoline 115,400 BTU/gal

Diesel 128,700 BTU/gal

Compressed Natural Gas 960 BTU/cubic foot

Ethanol 75,670 BTU/gal

Propane 83,500 BTU/gal

Biodiesel 117,093 BTU/gal



## Conversion factors to establish prices in dollars per

gasoline gallon equivalent are illustrated below, and

were developed using the lower heating values outlined

above. The conversion factors are derived in the manner

shown in the graphic to the right.

In the case of CNG, prices are provided to us in GGE,

so no conversion is necessary (the representative

heating value of CNG is provided above as a reference).

To convert a price from dollars per gallon to dollars per

gasoline gallon equivalent, multiply the price per gallon by the conversion factor.

GGE

CNG 1.00

Ethanol (E85) 1.41

Propane 1.38

Biodiesel (B20) 0.91

Biodiesel (B100) 0.99



## Conversion factors to establish prices in dollars per diesel gallon equivalent are illustrated below, and were developed using the lower

heating values outlined above. To convert a price from dollars per gallon to dollars per diesel gallon equivalent, multiply the price per

gallon by the conversion factor.
