1. GRADING THE OPTIONS:
In order to spend taxpayer money wisely and make smart
choices about our transportation policy, policymakers must
distinguish between policies, programs and technologies
that have a broad public benet and those or which the
benets are narrowly accrued by special interests. Consum-
er Watchdog has graded many o the technologies and uels
being debated in the planning or Americas energy uture.The details discussed in the handbook are important and o-
er some caveats to these grades, but in summary:
Grade A Hybrid, Plug-In Hybrid and All-Electric vehicles
Grade B Ethanol and Biodiesel ueled vehicles
Grade C Natural Gas ueled vehicles (higher grade or usein short-haul bus and truck feets)
Grade D Hydrogen ueled vehicles
Grade F Coal-based transportation uels
2. ENERGY MARKET OVERSIGHT AND REGULATION:
The neglect and demolition o reasonable government over-
sight o the oil industry has cost motorists billions o dollars
and wreaked havoc on the economy and the environment.
Energy markets and renery operations in particular suer
rom lack o modern regulation.
There are two crucial sources o unreasonably high pump
prices, both tied to the deregulatory ocus o national ener-
gy policy over the past several decades: rapacious specula-
tion o commodity traders both in and outside o oil compa-
nies and market manipulations by oil reners.
Energy commodity markets require a major regulatory
overhaul to distinguish between pure nancial speculation
and transactions involving actual buyers and sellers. All
trading should be ar more transparent; nancial specula-
tors, including nancial trading departments inside major oil
companies, should also play by tougher rules. These include
putting up more o the value o a trade in each transaction,
limits on highly complex trading schemes that can be mis-
used and overall limits on daily trades. In order to protect
against a speculation-driven and distorted global commodity
market or renewable uels, regulation o biouels must be
established in concert with the expansion o the biouels
market.
EXECUTIVE SUMMARY
This handbook oers solutionsor the most visible and perva-sive sector o the current oil/en-vironmental crisis: transportationby automobile. Americans travelmore than 3.5 trillion vehicle milesper year1 (not even including occa-sional long-distance drives). Theyace oten-staggering gasolinecosts and emit millions o tons opollutants. Our assessments andrecommendations aim at reduc-ing the use o oil as a personaltransportation uel while oer-ing consumers alternatives thatare ultimately both cleaner andcheaper.
Consumer Watchdog agrees withproponents o energy efciencyand conservation that both areast, eective ways to reduce alltypes o ossil uel dependence.These solutions are intertwinedwith vehicle use, and addressedhere only in that context, or ex-ample in higher CAF standards.Similarly, attention to mass tran-sit is essential. But mass transitwill not address the problems omillions o Americans who lackaccess to robust urban transit sys-temsmeaning most Americans.
In the handbook, we highlightpolicies aimed at more eectivelymonitoring and regulating the oilindustry and ensuring that theclean uels and technologies oour automobile uture dont be-come the next energy oligopoly.
We also grade the various alterna-tive uels in order to help policy-makers and the public assess thechoices or the uture o automo-bile transportation.

Oil rening has become a tool or oil companies and other
large players to manipulate uel supply to keep prices up.
The regional gasoline price spikes accompanying 2008s
Hurricane Ike were exaggerated by rener cutbacks that
had already let the nation with its lowest gasoline supply in
years. The price spikes ater Hurricane Katrina in 2005 were
even more dramatic and lasting, needlessly so. The Depart-
ment o Energy should have power to require an average
30-day national supply o gasoline on hand rather than therecent 20-22 day supply average. Reners should be re-
quired to report their cost o oil and their wholesale prices
or nished products, such as gasoline and diesel, to enable
regulators to prevent price-gouging at the wholesale level.
Renery industry data should be publicly available down to
the level o individual reneries, and ultimately renery pro-
its should be regulated along the model o public utilities.
3. RENEWABLE FUELS AND CLEAN VEHICLES:
Policy choices can transition our transportation system to
more ecient, cleaner and cheaper uels, without having to
pick the exact ormula. However, policy should be guided
by realistic, consumer-oriented thinking that does not en-
courage wasteul projects such as transportation uel rom
coal.
Hybrid vehicles and the coming generation o plug-in hy-
brid vehicles have ew environmental drawbacks; they can
calmly coexist with, and be improved by, biouels. Electric
hybrid-diesel vehicles, or instance, will be able to burnbiodiesel without modication and achieve higher mileage
than gasoline-electric hybrids. All types o dual-uel hybrids
should be encouraged.
Biouels promise is limited today not by the availability o
vehicles but by lack o ueling inrastructure and the draw-
backs o using crops as eedstocks. Policy decisions should
ocus on second-generation biouels and regulated develop-
ment o ueling stations at existing gasoline stations.
Compressed natural gas and propane are cleaner than gaso-
line and are useul transitional uels or urban bus and com-
mercial feets, such as short-haul trucks. Policy decisions
should encourage these appropriate uses, but not at the
cost o increased liquid natural gas imports or higher utility
rates.
Hydrogen remains a chimera, because o vehicle cost and
the energy cost o producing hydrogen as a uel. While its
promise o emission-ree vehicles will continue to entice ad-

herents, the lack o even remotely near-term viability makes
it a lower priority approach. Coal-to-liquid uel is no more
than a pork magnet or the coal industry, more polluting
than petroleum and a distraction rom better alternatives.
3. WHO PAYS, WHO BENEFITS:
Switching to a transportation economy that uses ar less pe-
troleum does not come ree, but the transition can be air--sotening costs to consumers through direct and indirect
subsidy and requiring corporations and shareholders to bear
part o the burden.
Congress must rst eliminate billions o dollars worth o
unjustiable petroleum subsidies and tax excess petroleum
prots, returning some o the proceeds to consumers and
investing the rest in renewable energy.
Carbon tax, auction and trade, or cap and trade systemsthat will be negotiated in Congress will garner billions in
ederal revenue. While these alternatives are not speci-
cally discussed in this handbook on transportation, oering
substantial consumer credits and other direct incentives to
oset the initial costs o reducing emissions will be impor-
tant in reducing transportation use o ossil uels.

INTRODUCTION
Transportation is the immediate and amiliar measure or consumers othe cost and quality o daily lie. Every driver knows the cost o a gallono gasoline. Every amily sees the strain o roller-coaster energy costs onits budget, while worries about global warming and pollution grow more
important to their daily decisions. Consumers want solutions, but they dontwant to be pick-pocketed to get there.
President Obama has stated that, despite the deep recession, a greenerenergy policy is among his top three priorities. The United States is ar moredependent than other developed nations on cars and roads, something thatcannot be switly undone. But it can become cleaner in aordable ways.
That is the point o this plain-language handbook, which gives grades oA to F or vehicles and uel choices based on their balance o cleaner andcheaper.
About 70% o the oil consumed in the United States is or transportation,which accounts or 30% o U.S. carbon dioxide emissions, second only topower generation. The U.S. goals o reducing oil dependence and slowingglobal warming will succeed or ail in large part on decisions by Congressand the president about transportation uels and vehicles.
The 2008 U.S. fnancial meltdown was accelerated by oil prices over $145 abarrel and motor uels topping $4.00 a gallon. A temporary, dramatic dropin uel prices and the serious economic recession will tempt policymakers
to delay action. But delay in developing strong transportation policies willurther weaken already shaky markets or alternative vehicles and uels,including new generations o biouels and plug-in hybrid vehicles. Stabilityis everything in sustaining new technology and creating the green jobs thatgo with it.
Wearied by economic recession and greed-driven corporate implosions,Americans will not trust policies that aid only corporate master plans.Government must be visible as a protector against corporate excessand market manipulation, in new green markets as well as traditionalenergy. Policies must create green jobs and cushion the costs o change or
individuals.
I government visibly gets oil markets and oil companies under regulatorycontrol, i transition costs are airly and transparently shared, and i theenvironmental benefts are clear, consumers will embrace the goal o acleaner transportation system that ultimately will be cheaper than staying onthe petroleum roller-coaster.

REGULATE ENERGY TRADING MARKETS:
Modernize regulation to account or and curb energytrades that are entirely speculative. Much o the 2008price spike in crude oil was driven by electronic trading mar-
kets in which only a raction o sales involved physical oer
or delivery o products. This nancial-only trading, known
as noncommodity trading, has purely prot-seeking goals,
unlike hedges against loss in the physical purchase and saleo energy products including oil and natural gas.2
Require higher margins rom fnancial-only trades.Margins, meaning the amount o a trades value that trad-
ers must pay up ront, are set as low as 5%-7% in energy
utures markets, unlike the 50% o value required upront
rom stock traders. The low margins were originally in-
tended to help producers and buyers hedge their own sales
and purchases without taking capital out o productive use.
Today, low margins and regulatory loopholes allow nan-cial speculators to control too much actual product or too
cheap a price. The margins on nancial-only trades should
be raised to match the stock markets 50% requirement.
Limit fnancial-only trades in size and requency. Regu-late and require ull disclosure o exotic energy trading
schemes that may have the intended or unintended eect
o increasing prices and price volatility. Set a hard daily limit
(say, 3 million barrels) or holdings o petroleum products
by the parent company o any trading entity across all trad-
ing platorms, not just those, like the New York MercantileExchange (NYMEX), that are currently regulated. The limit
must apply to the parent company to prevent a single owner
rom spinning o multiple unds to evade the limits.
Support dispersed markets or biouels. Oil and gaso-line operate as a worldwide integrated market because
gasoline is made rom a single, capital intensive eedstock.
That model alone will not nurture new generations o envi-
ronmentally superior and cheaper biouels, in which a vari-
ety o relatively bulky competing eedstocks with relatively
low capital requirements, (such as cornstalks, algae, wood
waste and switchgrass) can keep the new crude uels
prices lower. The 2008 ederal arm bill made a step in the
right direction in avoring small biodiesel producers (less
than 150 million gallons) or certain subsidies.3 That creates
more local jobs in the green economy and would tend to
establish pricing on actual regional cost o production. Fuel
rening and distribution must be integrated and centralized
enough to reach consumers eciently, with a watchul
1.BIG-PICTURE POLICY
ESSENTIALS
Regulation is essential in orderto create efcient markets thatprotect both investors and con-
sumers, as the fnancial marketmeltdown so sharply illustrat-ed. In energy markets, oil pricesthat rose in the summer o 2008to more than $145 a barrel, thenplunged to less than one-thirdthat price, demolished the excusethat only supply and demandwere at work. Gasoline prices ol-lowed the price o oil up, yet ellmore slowly as refners and mar-keters sought to recoup profts.
Neglect o regulation damagedconsumers, the economy and theenvironment. Roller-coaster pric-ing also creates start-and-stop de-velopment o renewable energysources.
As U.S. markets in renewable uelsdevelop, government must over-see and regulate them to preventthe market concentration, gaming
and profteering that surround thepetroleum industry.
Consumers also view excessivetax breaks or highly proftableoil companies as a ailure o gov-ernment to balance corporate de-mands with the common good.Oil company subsidies must berecaptured to und renewable u-els and energy, as well as directconsumer subsidies or greener
technology and reduced energyconsumption.

regulatory eye or market abuse as the systems grow.
REGULATE U.S. REFINERIES AND FUEL SUPPLIES:
A transition to cleaner, cheaper uels should not be an
excuse or oil companies to reduce supplies and make
higher prots rom selling less gasoline and diesel.
Even as the oil industry is demanding the right to drill inmore coastal waters, the rening end o the industry has
reduced production o uels, keeping national supplies low
in historic terms and thus subject to sudden price spikes
in the event o any interruption o production. In recent
years, the oil industry has oten exported uels or reduced
rening in order to maintain or increase upward pressure on
gasoline and diesel prices.4 And, with virtually no regulatory
oversight, the price o gasoline is easily disconnected rom
the price o crude, which is why as oil prices ell rom their
$145 a barrel peak in the autumn o 2008, gasoline pricesdropped much more slowly.
Low supplies o rened product make uel prices
excessively vulnerable to sharp price spikes in the event
o natural disaster or renery outages. The aims o public
policy should be to:
Makemorerenerydataavailabletothepublic.The
Energy Inormation Administration (EIA) already gathers
substantial detailed inormation on renery operations,
company by company. The EIA publishes days o supply o
gasoline available nationally but not regionally,5 as it doeswith the rate at which reneries in aggregate are utilized.6
Such inormation should be available by state, by region,
by company and individual renery. Currently, there is no
requirement that reneries even report outages, which
switly aect prices.7 In an industry as concentrated and
uncompetitive as petroleum and rening, this detailed
inormation should not be shrouded as a trade secret.
Intheeventoflowsuppliesandintheabsenceof
natural disaster, the Secretary o Energy should have the
power to require reners to produce uels at a rate that
keeps a 30-day average supply o gasoline and ethanol-
blended gasoline on hand nationally. This would return
supplies to the average o the early 1990s8 and greatly
reduce price volatility, under both normal conditions and
during natural disasters. The current average supply is 20-22
days and usually less in the West. Reneries nationwide
have recently operated at well below their stated capacity,
according to EIA data, even in periods o high prices,
particularly in 2006 and 2007.

Overseeimportsandexportsoftransportationfuels.
The Energy Secretary should have the power to slow uel
exports or increase imports in times o price or supply
emergency. For instance, as diesel uel prices were spiking
in 2008 to records near $5.00 a gallon in the West, reners
raised their exports o nished diesel uel.9 Government had
no mechanism to curtail these exports to protect the U.S.
economy.
Ifgreatertransparencyandoversightofthefuel
supply do not prevent rener gaming o supplies, institute
utility-style regulation o rening. Instead o requiring
regulatory approval o consumer prices, regulation should
be aimed at renery prot margins. While regulated
reneries would not suer long-term losses, they also
could not increase margins above a set long-term average.
Consumers would benet rom greater price stability.
Reners, both independent and integrated, would reap
an average prot based in part on their reinvestment inenvironmental upgrades.
Eliminateundergroundtanksthatstillholdmidgrade

and eliminating a separate midgrade storage tank at stations

a pump that mixes rom two underground tanks, as many

HYBRID/PLUG-IN HYBRID/ALL-ELECTRIC VEHICLES:Grade A
PRO: Hybrid vehicles are the quickest path to highermileage and lower petroleum use on the road. Conventional
hybrids established consumer popularity paves the way or
plug-in hybrids, dual-uel hybrids and possibly or all-electric
vehicles.
The current Toyota 46-50 mpg Prius and the 43-mpg Honda
Civic hybrid cost up to a ew thousand dollars more than
similar conventional cars. But in times o high gas prices, as
in 2007 and much o 2008, the time needed to pay back
the buyer through gasoline savings is as short as two to
three years, even without ederal tax incentives.10 Even the
new Ford Fusion hybrid, larger than the Prius, will get near
40 mpg.11
Commercial plug-in hybrids are expected to get up todouble the miles per gallon o conventional hybrids.
Diesel-electric hybrids engines get higher mileage
than gas-electric hybrid engines (all diesel engines get
comparatively higher mpg than gasoline engines) and would
have the added environmental advantage o being able,
without modication, to run on high-percentage blends o
biodiesel, or 100% biodiesel. Manuacturers currently see
diesel/electric passenger cars as too expensive or broad
consumer production,12 but diesel-electric engines are now
being produced by at least one heavy-equipment maker,Komatsu.13
The next-generation lithium-ion battery or plug-in hybrids
is expected to reduce the size, weight and cost o hybrid
batteries. Lighter and smaller lithium batteries, as a bonus,
are also showing crossover promise as power storage
medium or solar and wind power: Lithium battery storage
at power plants could thus recharge lithium car batteries at
night.14
Hybrids and electric vehicles will likely have lower lietime
engine maintenance costs because the engine design
has ewer moving parts, which reduces wear. This is an
anecdotal observation and a ripe subject or study.
The lie-cycle environmental benets o electric motors
and batteries will continue to improve as more electric
generation comes rom wind and solar, and less rom coal
and other ossil uels.

FUELS AND VEHICLES
Any successul eort to reducepetroleum dependence in the U.S.
will depend on cutting our use opetroleum uelsgasoline anddiesel. Heres an evaluation o al-ternative uel and vehicle possi-bilitieswhats good, whats bad,whats possible, and how to getthere.
Alternative Fuels Hybrid/Plug-In
Hybrid/All-Electric Vehicles
Hybrid-electric vehicles run on con-
ventional gasoline or diesel engines
that are boosted or partially replaced
by electric batteries that are more
advanced than the amiliar lead-acid
batteries in conventional autos. They
are recharged while driving, especial-
ly when the car brakes or slows. The
more powerul the battery in relation
to engine size, the greater the uel
savings. Plug-in hybrids, which are
nearing commercial introduction, run
or at least tens o miles on batteryalone, urther reducing uel usage
and nearly eliminating uel use or
average urban commuters. Batteries
are recharged during driving and with
an exterior plug. All-electric vehicles
skip the conventional engine and run
on rechargeable batteries alone, but
or a limited number o miles beore
recharging.

CON: The clean-air and greenhouse benets o electric andplug-in hybrid vehicles are diminished to the extent that
their recharging power comes rom coal and other ossil
uel-burning power plants.
Plug-ins and all-electric vehicles at this point carry a hety
price premium, which may all with larger production.
Large vehicles, including SUVs, that are marketed as hybridsoer a low percentage improvement in mpg because o
small battery size in comparison to engine size. They are
a marketing tool used as greenwash or carmakers overall
low mpg and an excuse or oten ridiculously higher sticker
prices.
While plug-ins will recharge o o conventional household
current, and run on gasoline as necessary, all-electric
vehicles ace a dearth o public or corporate charging
stations. One pilot commercial project may set up electric-car battery swap stations in Northern Caliornia and Israel,
but most major auto manuacturers have so ar declined to
participate, limiting the stations reach.
Hybrid-vehicle batteries, i disposed o improperly, could
pose an environmental threat. However, current hybrids
nickel-metal-hydride batteries pose substantially less threat
than conventional autos lead-based batteries.15 The next
generation o lithium-ion batteries will pose even less
environmental threat, according to Environmental Deense.
POLICY RECOMMENDATIONS:
Consumer tax credits. Restore purchaser tax credits andcarpool-lane incentives or the highest-mileage current
hybrids. A $1,500 credit would make the current crop
o hybrids competitive with gasoline engines. Transer
the credits to plug-in hybrids as they become widely
available. Develop consumer education about the longer-
term gasoline savings that would pay back any remaining
dierential in initial price.
Federal incentives. Stabilize and extend ederal incentivesor U.S.-based hybrid vehicle development and production. In
turn, require dened mpg goals or subsidies, and agreements
to create extensive green-collar job training and hiring.
Battery disposal. Follow Toyotas lead. Toyota has themost comprehensive battery recycling program, including
a $200 bounty payment or batteries that slip through the
recycling net.

Diesel hybrids. Encourage diesel-electric hybrid enginedevelopment or public transit, heavy equipment and, as
cost-appropriate, or passenger cars. Diesel hybrids get
higher mileage than gasoline hybrids, and ultra-clean low-
sulur diesel uels make such hybrids desirable even without
biouels.
Higher MPG standards. Further increase U.S. feetmileage requirements (CAFE standards) to at least 40mpg over the next 15 years to push development o better
hybrids and lower-cost electric/plug-in vehicles.

ETHANOL: Grade B
PRO: Ethanol, which is made in the U.S. primarily romcorn, can also be made rom multiple renewable plant and
even waste sources.
Ethanol displaces petroleum and increases U.S. energy
independence. The 2008 energy price crisis would have
been even more painul without the small percentage oethanol that is already blended into conventional gasoline.
Gasoline blended with up to 10% or 15% ethanol produces
a cleaner-burning uel or use in any gasoline-powered
vehicle. Commercially produced fex-uel vehicles run on
either gasoline or a blend o 85% ethanol and 15% gasoline
known as E85.
The corn ethanol industry has created skilled U.S.-based
industrial jobs, inrastructure and a business model oruture cellulosic ethanols made rom more desirable
eedstocks, including agricultural and orest waste, even
algae.
Such second-generation ethanols, which are in
development in the U.S., have a higher uel eciency and
a cleaner-than-corn environmental lie-cycle prolewhats
called in the petroleum industry a well-to-wheels emission
assessment. For instance, Brazilian ethanol made rom
sugar cane produces more and cleaner ethanol per pound o
eedstock than corn.
CON: Corn ethanol uses a major world human and animalood crop (though the byproduct let ater ethanol is made
can be blended with animal eed). Corn ethanols lie-cycle
environmental benet, i it includes emissions rom plowing
new cropland and industrial agriculture practices, is low.
However, this can be a deceptive measurement in that it
usually omits comparison with the dirtiest oil sources, such
as tar sands.
There is little ueling inrastructure or E85 ethanol uel.
There are more than 1 million fex-uel vehicles on the
road16 but only 1,200 to 1,800 E85 ueling stations out o
140,000 lling stations in the U.S. Many o the E85 stations,
however, are private or or feet cars only. Public stations are
heavily concentrated in the Midwest corn belt. In Caliornia,
or instance, there are only three public E85 stations.17

pumps at their branded stations with harsh restrictions in

Alternative Fuels Ethanol
Ethanol is an alcohol uel, lighter than
gasoline, that can be produced rom
all kinds o plant sources and even
household waste sources. Its the
uel equivalent o moonshine, and is
by nature high-octane. Most gaso-
line engines, with modications to
increase the compression ratio, can
run on ethanol. It produces ar less
tailpipe emissions, particularly o the
greenhouse gas carbon dioxide, than
petroleum uels. Ethanols overall
emission reductions, however, de-
pend in large part on what eedstock(crop or other biological source) is
used to produce it.

their contracts with dealers- -or instance orcing stations
seeking to test the alternative uel market to erect separate
(and costly) ueling areas or biouels, including E85.18 Most
U.S. fex-uel E85 vehicles run largely on gasoline or lack o
a convenient place to uel up with ethanol.
Ethanol gets up to 25% ewer miles per gallon than
gasoline, though this depends on how the engine is tuned:
Ethanol burns most eciently at higher engine compressionthan gasoline. Because fex-uel vehicles are tuned primarily
or gasoline, their mileage on ethanol is markedly poorer.
POLICY RECOMMENDATIONS:
Federal credits: Continue and extend ederal unding orcellulosic ethanol technologies, but continue corn ethanol
tax credits at a level that preserves inrastructure and green
jobs. Shit unding rom corn to cellulosic technologies
as they prove commercial scalability. Increase assistanceprovided in the 2008 arm bill to help corn ethanol
companies retool or new eedstocks, preventing plant
closures. Dont try to pick a winner, which would repeat
the market distortion caused by backing corn ethanol
exclusively in the 1990s.
Fueling stations: Build ueling inrastructure or E85.Require that oil companies remove contractual barriers to

low-cost loans and grants to station operators.
Flex-uel vehicles: As ueling inrastructure increases,allow and encourage actory and owner re-tuning o fex ue
vehicles to avor more ecient use o E85. This may require
modest Environmental Protection Agency and state-level
changes in emission regulations.
MPG standards: Increase U.S. vehicle feet mileagestandards (CAFE standards), while continuing mileage
allowance or ethanol.
Cane ethanol: In the short term, consider liting taris orlimited imports o more ecient Brazilian cane ethanol.
Establish limits that prevent rainorest destruction and
protect domestic cellulosic technologies.
Also consider more ethanol imports rom Caribbean Basin
nations. The ederal Caribbean Basin Initiative already allows
substantial imports without tari, and transport costs would
likely be lower than rom Brazil.

BIODIESEL: Grade B
PRO: The diesel engines that run almost all heavy trucksand trains get substantially higher mpg than gasoline
engines, and biodiesel is the cleanest renewable uel.
Almost any diesel engine will run on a biodiesel mix up to
B90.
Like ethanol, biodiesel replaces petroleum, increasingenergy independence.
There is promising research on producing biodiesel rom
algae, which would ease pressure on soybeans, currently
the chie commercial eedstock or biodiesel. The uel
can also be produced rom animal at waste rom meat
production, recycled used cooking oil or any plant-based oil.
The production o biodiesel is less complicated than or
ethanol, simple enough that make-it-yoursel instructions orthe dedicated and thrity are copious online.
CON: Virgin diesel made rom soybeans, while simplestrom an industrial-production viewpoint, displaces a ood
crop. Higher soybean use in uel, high oil prices and planting
o corn in ormer soybean acreage all aect price.
Soybean prices in spring o 2008 had near-tripled rom a
year earlier, making soy diesel uneconomical to produce
despite high diesel uel prices. Biodiesels price remained
uncompetitive with petroleum diesel uel at the end o2008, though the price o soybeans had dropped ar o its
high point.
Biodiesel has a variably lower energy content than
conventional diesel.
Truckers are wary o variable uel quality and biodiesels
higher gelling temperature, which makes it a dicult uel
in cold climates.
POLICY RECOMMENDATIONS:
Encourage B20 Use: The 2008 arm bill encourages useo 20% biodiesel uel in government vehicles. Even when
biodiesels price is above that o diesel, such blending is a
clean-air boon and should be encouraged with long-term tax
credits. A B20 mileage credit extension in the 2007 energy
bill should not, however, be construed to extend CAFE
standard credits to all diesel passenger cars and light trucks,
2.ALTERNATIVE TRANSPORTATIONFUELS AND VEHICLESCONTINUED
Alternative Fuels Biodiesel
Biodiesel uel is usually a processed
vegetable oil, and in act most diesel
engines will run on Costco-sized cans
o any cooking oil. Engines run better
on rened biodiesel, which is simple
enough to make that internet recipes
or biodiesel are numerous. It can
also be produced in large industrial
quantities. The original diesel engines
ran on peanut oil, until petroleum die-
sel took over the market.

any more than use o 10% or 15% ethanol would extend
such mileage credits to gasoline vehicles.
Require that vehicle warranties extend to use o biodiesel
blends. Currently, manuacturer warranties are construed to
orbid use o a blend above B5 in diesel passenger vehicles
without breaking the warranty. Legislation is necessary to
require that new-vehicle warranties remain in eect with
at least B20 blends immediately, with a brie phase-in orhigher biodiesel blends.
New sources: Intensive publicly unded university andother eorts are needed to determine i completely
renewable and nonood sources, including algae, can be a
successul commercial eedstock or biodiesel. Feedstocks
not linked to arm and energy commodity prices would tend
to stabilize uel prices.
Other sources: Animal at biodiesel lags in commercialproduction. Private commercial projects, such as a much-trumpeted but now dormant deal between chicken producer
Tyson Foods and oil company Conoco Phillips, appear
to be based entirely on the availability o $1.00-a-gallon
ederal credits. These credits are now uncertain. Such joint
ventures research and production results should be made
available to government and university researchers on the
basis o ederal subsidies already provided.
Waste oil rom restaurant ryers, once ree or the taking,
remained at about hal the cost o soy eedstock in 2008.But localized rening acilities need encouragement in
areas where this waste oil, known commercially as yellow
oil, remains underused. Las Vegas, Nev., or instance, has
a municipal policy to reap and rene this yellow oil rom
casino restaurants, and uses it to help run a school bus
feet.19

NATURAL GAS: Grade C
PRO: Natural gas is more abundant domestically thanpetroleum; 80% o current U.S. usage is domestically
produced.
Compressed natural gas (CNG) is much cleaner at the
tailpipe than gasoline or diesel or smog-causing pollutants.
CNG is a suitable cleaner-air alternative or certain large
diesel feets. This includes urban package delivery trucks,
municipal buses and short-haul trucking, or instance
at ports and grocery distribution centers, where gas
compression and vehicle ueling are easily centralized.
CNG, while highly variable in price even within regions, is
oten cheaper per gallon-equivalent than diesel uel.
CON: Natural gas is a ossil uel and releases more carbonemissions than other alternatives including current gas-electric hybrid vehicles.
The use o natural gas as a transportation uel will compete
with its use in electric generation, increasing the potential
or a new dependence on oreign energy sources. U.S.
natural gas imports are already increasing year over year.
Increased CNG use will raise natural gas prices (which hit
records in 2008) and increase pressure or imports o high-
sulur, less-clean liqueed natural gas. Such imports wouldrequire building controversial industrial LNG terminals and
storage along coastlines.
Higher prices or natural gas will raise consumers electric
bills. This could press utilities to turn back to coal.
There are ew public CNG lling stations nationwide. Fueling
requires special tanks and complex high-pressure saety
connections that are incompatible with current gas stations.
Home ueling or private cars requires a costly compressor
that takes up to 16 hours to ll an auto tank with a 200-mile
range.
POLICY RECOMMENDATIONS:
Encourage compressed natural gas as a transitionaluel or large engines. Shit appropriate bus and truck feetsto compressed natural gas as wind and solar utility power
generation increases, reeing natural gas supplies.
2.ALTERNATIVE TRANSPORTATIONFUELS AND VEHICLESCONTINUED
Alternative Fuels Natural Gas
The natural gas that powers electric-
ity production and household stoves
can also be compressed and used
as a vehicle uel, in special high-
pressure vehicle tanks. Some propo-

ducer T. Boone Pickens, are urging
widespread use o compressed nat-
ural gas (CNG) to reduce petroleum
imports.

Control vehicle use o CNG to prevent natural gas pricespikes. A controlled shit will also reduce pressure to build
new liqueed natural gas import terminals, which undercut
the goal o increased energy independence.
Discourage production o private autos and light trucksthat run on CNG. The commercial CNG ueling apparatus,
which requires large compressors, is largely incompatible
with current ueling inrastructure, unlike that or renewableethanol and biodiesel.

While Caliornia Gov. Arnold Schwar-
zenegger is a big an o hydrogen
uel, and even has a Hummer cus-
tom-converted to run on hydrogen,
he cant drive it outside Los Angeles
or lack o ueling stations. Hydrogen,
i it ueled a commercially competi-
tive vehicle and was produced with-
out ossil uel energy, would truly be
a zero-emission uel. But that goal is
distant.
ge 20
HYDROGEN: Grade D
PRO: Hydrogen uel produces zero tailpipe emissions inuel-cell vehicles.
Researchers see promise in producing hydrogen rom water
with solar power.
CON: The prediction o a hydrogen highway is mostly hotair, defecting attention rom more developed and aordable
alternatives.
Commercial hydrogen production currently requires natural
gas as eedstock, requires copious energy and high-
temperature steam, and emits CO2. The process requires
nearly two times the energy that the hydrogen uel will
produce.
The technology required or current hydrogen productionavors large corporate inrastructure, as in vertically
integrated oil companies. A concentrated production
inrastructure may lead to an uncompetitive, high-cost
market.
The cost o the engine is prohibitive. Hydrogen vehicles
are currently handed out or testing to celebrities,
or on money-losing leases with complicated servicing
agreements.
Fueling stations are rare and hydrogen vehicles rangeremains somewhat limited.
POLICY RECOMMENDATION:
Continue research, particularly o solar- or wind-powered
production o hydrogen uel rom water. Put urther
incentives on hold.

Fuels
The production o liquid uels rom
coal is a longstanding technology;
such uel was intensively produced

However, even the costly process o
turning coal into uel releases about
hal o the coals C02 into the atmo-

COAL-TO-LIQUID FUELS: Grade F
PRO: U.S.-produced, replaces petroleum as a uel.
CON: Coal-to-uel production emits substantial greenhousegases even beore the uel is used.20
The uel itsel is not cleaner than gasoline.
The mining o coal causes wide environmental damage,
including mountaintop removal, stream destruction, water
pollution and even more CO2 emissions.
POLICY RECOMMENDATION:
Forget it as a transportation uel. Coal-to-liquid hasno benet to equal its environmental damage. Continue

The shit rom a petroleum-based transportation economy
to a cleaner mix comes with start-up costs, including
subsidies or new technologies and uels. The end result
could be big savings or the majority o Americans
compared to a petroleum-based transportation uture i:
Speculativeenergymarketsareintelligentlyregulatedand
made more transparent;
Energy market prices are stabilized to dampen the boom and
bust cycle in green energy investment;
Current ossil uel subsidies are redirected to green
technologies and to individual consumers;
Subsidies or development o greener uels and vehicles are
unded through broad-based ederal and state revenues rather
than markedly higher uel taxes, which proportionately burden
the middle and working classes;
Green uel markets are kept honestly competitive and
domestic job creation is emphasized; and
Subsidies or politically popular but unpromising technologies,
such as hydrogen vehicles and coal-to-uel, are eliminated.
Subsidies: Elimination o ederal oil royalty relie,particularly contracts issued in error in the late 1990s
without oil-price thresholds or royalty payment, would cut
taxpayer aid to the oil industry by up to tens o billions o
dollars over 25 years, depending on oil prices, according to
the Government Accountability Oce.21 Royalty contracts
are currently under litigation in ederal courts, but should be
settled more quickly by Congress with orced renegotiation.President Obama has also proposed a new tax on Gul o
Mexico oil production to oset the unjustied royalty relie.
Elimination o other subsidies, including production and
depletion credits and research and development credits that
have not produced visible results, would reap in the single
billions. The record prots reported by major integrated oil
companies since 2003 have let them with cash hoards that
obviate any need or taxpayer unds. Petroleum subsidies
should be redirected to green uels and vehicles, including
direct purchaser subsidies.
Market Regulations: Price stability or ossil-uel energysources, particularly petroleum, is key to keeping up
momentum or greener vehicles and uels. Futures markets
that rose to $145 or a barrel o crude oil, then dropped to
$35-$40 in a matter o months are unhinged rom supply
and demand. At the bottom end, crashing prices cut o
investment in renewable uels and energy sources, and
even uel defation. At the top end, high energy prices
damage consumers and the economy.

Eective utures market controls, including transparent
reporting o trades in real time and limits on the trading o
parent companies, would cut o the top and the bottom o
the oil price/energy price roller coaster, with more taken o
the top than the bottom. Relative price stability would result
in lower average uel prices but also allow more stable
investment in both traditional and green markets.
Regulation has little direct cost. It requires smart design,resistance to nancial lobbies and commitment to
enorcement. Futures market enorcement will required
added sta at the Securities and Exchange Commission,
the Commodity Futures Trading Commission and other
bodies, proposals that are already beore Congress.
Refning Regulation: Regulation o petroleum reningwould also dampen roller-coaster prots. Recently, as in
much o 2006 and 2007, reners have deliberately cut
production aster than demand has dropped, to increasetheir prot margin. Federal law should set a baseline or
regulation and allow the states to carry it out, with locally
specic variations. In highly concentrated markets like the
Western states, ull utility-style regulation o rening, like
that o electric utilities, could produce the best outcome or
both consumers (who would pay more stable and overall
lower prices) and reners, who could earn a lower but more
stable prot margin.
VEHICLES AND FUELS
Hybrid and electric: Direct but temporary costs totaxpayers and government in subsidies or development
o high-mpg plug-in hybrids and electric vehicles will be
temporary. Conventional hybrid vehicle prices are stable or
dropping, and a renewed purchaser tax credit would keep
the market viable during the current recession and its lower
uel prices. In times o higher uel prices, hybrids higher
purchase costs are recouped in a ew years through uel
savings, and owners save substantially more over the lie o
the vehicle.
The longer-term cost o encouraging plug-in hybrids and all-
electric vehicles is in reducing use o ossil uels, particularly
coal, or generating the electricity that will run the cars.
Switching to green-generated power is a broader issue than
auto battery recharging, but electric cars cannot reach their
potential without clean power.
The simplest saving is reduction or elimination o lavish
direct coal subsidies, including nearly $2.9 billion in the

2007 energy bill. (See Coal section below) Such subsidies
or the dirtiest power source make coal appear cheaper than
it actually is, and make green power look too expensive.
The barrier to recouping these subsidies is not logic or
necessity but the power o the coal-states lobby, particularly
in the Senate.
The costs o coal-plant replacement will be high but one-
time costs, and subsidies now given to the industry shouldlargely be redirected to utility customers to oset their
higher utility costs.
Wind power is already competitive with natural gas; thin-
lm solar may be price-competitive at commercial scale.
The use o small-scale solar generation in and close to
urban centers would also save billions o dollars on the
building o costly new transmission lines.22
In almost any scenario, however, electric recharging ovehicles would remain cheaper than purchasing gasoline or
diesel uel.
Ethanol and biodiesel: Flex-uel vehicles capable orunning on E85 ethanol uel are generally priced the same
as gasoline models. E85 is also generally cheaper than
gasolinein agricultural states like Iowa, oten 20% or
more cheaper, osetting any loss o mpg. Virtually any
diesel engine can run on biodiesel, but the price o pure
soy biodiesel at the pump has generally been a ew to
tens o cents higher than petroleum diesel. This price gapshould diminish i all uel prices are stabilized and biodiesel
availability increases.
Thus the costs associated with ethanol and biodiesel
are mostly related to research, development o non-crop
eedstocks or the uels, direct subsidies to producers and
increasing retail availability.
Research and development subsidies already are ocused
on non-corn ethanol, though commercial development has
slowed due to the sagging economy and the lower price
o oil and uels. Stabilization o energy utures markets and
uel prices through oversight and regulation will encourage
private investment in clean uels, reducing direct public
costs.
Compressed natural gas: Taxpayers should not subsidizedevelopment o CNG-ueled personal vehicles or mass-
market ueling stations. Temporary subsidies should
be limited to urban public transit and short-range truck

feets that can uel at central yards. Wider subsidies or
CNG vehicles would raise natural gas utility rates, tempt
utilities to buy more coal power, increase production
o environmentally destructive coalbed methane and
encourage imports o dirtier-burning liquid natural gas. CNG,
as an automobile uel, is not on the path to cleaner and
cheaper.
Hydrogen: The high dollar cost o hydrogen uel cellsand the environmental cost o producing hydrogen uel
rom ossil uels should rule out subsidies or hydrogen
vehicles, which are not much closer to market-competitive
commercial production than they were in the 1970s.
Taxpayer dollars would be better spent on less splashy but
cheaper and more immediate uels and technologies.
Coal: Fuels derived rom coal are all cost and no benet,the purest denition o industrial pork. Federal coal
subsidies--not just or coal-to-uel but or coal productionand coalbed methane --should be redirected to consumers
and to environmentally saer uels and technologies. Current
subsidiesare driven by the coal industry in the same way
that corn-only ethanol subsidies were driven by industrial
agriculture.
