Both major party candidates for
president say the nation’s economy and
national security are closely tied with
its energy policy. But they each have
a different plan to build the market for
alternatives to foreign oil and other
fossil fuels. In the next part of our
series about shifting the nation’s energy
policy, Julie Grant takes a look at the
candidates’ views on renewable power, like
wind and solar:

John McCain and Barack Obama both talk a lot about new
sources of energy on the campaign trail. They see
alternative energy as a way to reduce our dependence on
foreign oil, to stem climate change, and even to boost the
economy.

McCain: “It’s wind, tide, solar, nuclear, offshore drilling.”

Obama: “That’s why I’ve focused on putting resources into
solar, wind, biodiesel, geothermal.”

Every president since Richard Nixon has promised to reduce
America’s dependence on foreign oil – but our imports have
only increased since the 1970s.

So what are each of this season’s contenders proposing?

Obama has been talking about huge investments in clean
technologies and energy efficiency.

“My energy plan will invest 150-billion dollars over the next
ten years to establish a green energy sector that will create
up to five million jobs over the next two decades. Five
million jobs.” (applause)

Obama wants to retrain steel and auto industry workers for
jobs building wind turbines and solar panels.

Wind energy is already contributing energy to the nation’s
electricity supply. Solar isn’t quite there yet. It needs more
research.

Edward McBride is energy and environment correspondent
for The Economist magazine. He says Obama plans direct
government investments in wind, solar, hybrid electric cars,
and making homes and businesses more energy efficient.

“He imagines a situation where the government is much
more heavily involved, not just in providing incentives but
actually in spending money. And therefore presumably the
government is in a position to pick and choose more which
technologies move forward.”

Unlike Obama, Senator McCain doesn’t plan direct
government investment in clean technologies. Instead,
McBride says the McCain is proposing tax credits for those
who do invest in them.

“He wants more broad-based incentives. Rather than
different incentives for solar and wind and so on. He wants
one unifying tax incentive.”

But McCain plans some direct government subsidies – for
nuclear and clean coal.

And although McCain talks about building a green economy
on the campaign trail, he doesn’t always seem convinced
that clean energy will provide the power America needs.

Here’s McCain speaking in New Hampshire last December.

“Most every expert that I know says that if you maximize that
in every possible way the contribution that that would make
given the present state of technology, is very small. It’s not
a large contribution. Even if we gave it the absolute
maximum, wind, solar and tide, etc. The truly clean
technologies don’t work.”

McCain is counting on the investment markets to decide
winners and losers in the renewable energy business.

But the markets don’t usually look long term, at things like
climate change. So both presidential candidates are
planning to put a price on burning fossil fuels, such as oil
and coal, that add to the problems of climate change.

That alone could provide another incentive for clean
competitors.

Cellulosic Ethanol Breaks Ground

Getting fuel from plants like corn
and sugar cane is not that efficient. That’s
why researchers are working on so-called
cellulosic biofuels. The process turns things
like corn stalks, wood chips, and grasses into
fuel. As Mark Brush reports, some new
cellulosic refineries are breaking ground:

The new refineries are being built with money from the federal government. The hope is
to perfect a fuel source that a) doesn’t come from food, and b) is much more efficient
than corn-based ethanol.

The problem is it’s hard to get at the sugars inside the
plants. But the payback could be big. For every one unit of energy going in,
cellulosic ethanol could spit out about five to ten units of energy.

Brian Davidson is with the BioEnergy Science Center. He says industry officials are
hopeful, but he thinks these new refineries are just a first step.

“They believe that those technologies will be more widely applicable, but I actually
believe that we’re going to need further technology improvements to go from these first
few handful of plants, handful of bio-refineries, to make them widespread.”

Davidson says scientists still have not perfected ways to break down the plants in a
cost-effective way.

High School Student Is Biofuel Whiz-Kid

It’s hard to be optimistic about
paying $4 a gallon at the pump.
But when you’re a teenager working on new
ways to make cheap fuel, it can be pretty
exciting. Julie Grant met one high school
student who is showing off his biodiesel
converter at the county fair:

(sounds of the fair)

The Fairgrounds sit in a quiet countryside of rolling green
hills. Small children yell and wave to family members as
they enter the Fair. There’s a steer auction in the barn. And
an antique tractor pull in the grandstand.
It’s like a scene is right out of a Norman Rockwell painting.

I’m here to talk with John Russell. He’s walking around in
faded wrangler jeans. A red t-shirt with the sleeves cut off.
And a ballcap advertising a tractor company.


“We’re at the Columbiana County Fair in Lisbon, Ohio. In
the junior fair building.”

John is 17 years old, and amidst 4-H project displays, he has
set up his view of the future. His homemade biodiesel
converter.

It’s a rectangular box – nearly as tall as me.
It’s made of stainless steel. There’s a row of toggle switches
along the side. They light up when John plugs it in. He’s
been working on this for more than a year, and says it
makes vegetable oil into a usable fuel.

“I started out with new oil from Save-A-Lot. I went down to
the local grocery store and picked up a bottle of frying oil.
And just from a recipe I found online, with methanol from an
auto parts store, they sell it as heat. It’s gasoline antifreeze.
Just methanol from an auto parts store, Caustic soda from a
hardware store, and oil from a grocery store, I set out to
make this fuel. And it took me couple of times. I finally got it
right when I actually tried a batch of waste vegetable oil from
the valley drive in. So that was my first successful batch.”

Last year, John was only able to fill a Gatorade bottle with
his fuel. Soon, he expects to convert 240 gallons of
vegetable oil into biodiesel in a day.

He hasn’t quite figured out how much the electricity costs to
run the thing, so he doesn’t know how much it’s costing him
to make the fuel.

Back five years ago, he met a guy who claimed to be making
biodiesel for 46 cents per gallon.

Headlines then were already screaming about skyrocketing
fuel prices. 1.60 per gallon. That’s what sparked John’s
interest in making his own converter.

“46 cents a gallon was pretty cool. And I’m into sustainable
agriculture. It’s recycling and its ecofriendly. The
culmination of all those things, that’s what makes it
interesting for me.”

Now that’s he’s almost 18, most of John’s friends are into
cars. And they’re taking an interest in his biodiesel project.

John Russell: “I’m a senior in high school. So most of my
friends’ reactions are ‘when are you going to give me free
fuel?’ But they all think it’s pretty sweet. It does make fuel a
lot cheaper than you could buy it at the pump.”

Julie Grant: “How much are you selling it for?”

John: “Well, I can’t sell it. Or else I’ll get in trouble with the
big man.”

Julie: “Is your dad the big man?”

John: “no. The IRS.”

He’s got to do some research into state and federal laws.
John wants to use the fuel to run his family’s tractors and
help heat homes in his neighborhood.

He’s not sure if biodiesel is the future of fuel, or even in his
long term future. But John is sure he wants a career in
green industry.

“Anything that’s gonna be tied into this fuel situation that
we’re faced with. Something’s gonna change and
something’s gonna change fast. So I’m very excited for
what’s going to happen.”

For now, John’s trying to put the finishing touches on his
converter so it’s ready for the Ohio state fair later this
summer. He’s the new face of agriculture – making eco-friendly practices into traditional American values.

For many people, the summer road
trip includes trips to the beach, and of
course, frequent stops to the gas station.
Two college students are driving across the
country in a car that runs on used vegetable
oil. So when most people pull in to the gas
station this summer, they pull up to the
grease traps. They say it’s a way to raise
awareness about alternative fuels, and save
a bit of money. Katie Carey brings us this
audio postcard:

MATT: My name is Matthew Rolen Stucky. I am taking this ’85 Mercedes Benz Diesel
with a grease car kit, putting old vegetable oil that we find from restaurants along the way
and sticking it in and making it go.

DEVIN: Hi, I’m Devin and we’re getting our fuel for the car from mainly restaurants
from the deep fryer. They dispose of the grease and we just take that and filter it a couple
times.

MATT: Well I pre-filter it – it’s basically a water filter. I have a couple mesh filters that
it goes through and then it goes through a second gas tank where it heats up and runs
through the car and then has one more engine filter that it goes through secondary. You
can drive this around everyday nearly in every situation and it doesn’t slow down your
gas mileage you have the same top speeds, the same acceleration, literally you will not be
able to tell the difference, until you realize you’re not buying the gas, and then you are
happy about it.

DEVIN: We have a journal in the car and we have a tally of how many hummers we’ve
seen on the road trip so far and I think the tally is to sixteen, and we kind of do a little
‘ha-ha’ every time we see one. Just because we know how much they are spending on
gas.

MATT: The reactions range from people saying, “Oh yeah, you are putting it in your car,
great, yeah here take it.” To people going “You do what? What does it do in your car?”
And they don’t believe it and they want to go see it sometimes.

DEVIN: Some people this is the first grease car they have ever seen and they just think it
is awesome that someone is out there doing it. It’s not a solution for everyone, again,
there’s not going to be waste vegetable oil for every single person that wants to drive in
the car around the country, so it definitely is not a solution to the fuel crisis. It’s just us
trying to do our part to raise awareness.

Green Fuel From Green Slime

When people talk about bio-fuels,
they usually mean ethanol from corn or diesel
fuel from soybeans. But there are lots of
possibilities. One of them is algae. Algae
contains a lot of oil. The US Department of
Energy experimented with algae for nearly
twenty years after the oil crisis of the 1970s.
But with fuel prices so high, scientists around
the world are looking at algae again. Stephanie
Hemphill reports one researcher thinks
he’s figured out how to grow lots of algae, fast:

Roger Ruan has been trying for years to figure out how to turn algae into diesel,
economically. He’s the director of the Center for BioRefining at the University of
Minnesota.

Ruan says there’s no question it can be done; some people are already producing algae
oil. They’re growing it in open ponds. It’s used for pharmaceuticals, food supplements,
and cosmetics.

“Right now, based on an open pond system, per acre per year, you can easily get 5,000
gallons of oil, and soybean would probably give you 50. That’s 100 times difference.”

So algae can be far more efficient at producing diesel fuel than soybeans. But how do
you grow enough algae to make a dent in the nation’s energy demand?

Ruan is turning to an unlikely partner: the local sewage treatment plant.

“Wastewater has lot of nutrients: phosphorus, nitrogen, are all available in wastewater,
and actually you spend lot of money to remove these from wastewater, so if we can kill
two birds with one stone, that would be the best, and that’s what we’re hoping to do.”

(sound of treatment plant)

St. Paul, Minnesota’s sewage treatment plant sits on the bank of the Mississippi River.
The basement of the building where the solids are separated from the liquids is a
brightly lit space. It’s filled with big steel pipes and valves and tanks.

Off to one side, Ruan’s team is setting up a rack of aquariums – the future home of juicy
green algae. When everything is ready, some of the partially-treated waste will be
diverted into the tanks, where it will feed the algae.

The waste is still full of stuff that’s bad for the river, but good for algae.

“It’s got a fair amount of phosphorus, and some ammonia nitrogen that the algae are
going to need.”

Bob Polta is manager of research and development at the treatment plant.

It’s easy to see why he likes this idea: every day the facility has to remove 4 tons of
phosphorus and more than 16 tons of nitrogen from the waste stream.

The algae experiment, if it works, will allow them to do some of that removal in a more
cost-effective way. And this could be the answer to Roger Ruan’s problem of trying to
create enough algae to make enough oil to compete with petroleum diesel.

Polta says there’s a big potential, both for cleaning wastewater and for producing
energy in the same place.

“All the wastewater treatment ponds in the small communities around the state are
essentially using algae to treat wastewater; it’s just that they’re not being harvested. It’s
just that we’re getting two goals together here, and two research groups, one is essentially taking algae and
harvesting the oil and making biodiesel, and the other is using algae as a treatment
scheme, and to see if we can make this thing really fit.”

Polta expects by the end of the year he’ll know more about whether this is a practical
idea.

Roger Ruan says within six-to-ten years someone, somewhere, will be producing diesel
from algae on a commercial scale.

Biofuel Blends Fail Tests

Transcript

In the US, the market for biodiesel was more
than 450 million gallons in 2007. But new research shows
not all biofuels are created equal. Lisa Ann Pinkerton
reports:

The American Chemical Society study tested 19 biodiesel samples
from states like California, Massachusetts, and Indiana. It found the
majority, almost 90%, didn’t meet federal requirements for B20 grade
fuel – 20% biodiesel, 80% petroleum. Some samples
contained as little as 2% biodiesel, while others exceeded the
20% limit.

One of the study’s authors is Christopher Reddy. He says biodiesel
above 20% could damage engines, while anything below 20%
reduces the environmental benefits.

“So perhaps the results of my small study will help people take a step back and
reevaluate things and put in some safe guards and such.”

Reddy’s says his study shows the blending inconsistencies found by
the National Renewable Energy Laboratory in 2004, still haven’t been
addressed.

Bush Pushes for Renewable Fuel Program

The Bush Administration is proposing a Renewable Fuels Standard Program. It aims to
double the use of renewable fuels such as ethanol and biodiesel. The GLRC’s Lester
Graham reports:


This new regulation would require more renewable fuels at the pumps. The Bush
Administration predicts we’ll cut petroleum use by nearly four billion gallons a year.
Most of those fuels are expected to come from crops such as corn for ethanol and soy
beans for soy-diesel. But some scientists say using food crops for renewable fuels is a
short-term fix.


That’s because it takes a lot of energy to produce ethanol from corn. At best, the net
energy gain in growing, harvesting, and processing corn into ethanol is: one energy unit
input producing a one-and-a-quarter energy unit output. And, ethanol production has been
heavily dependent on government subsidies.


The Environmental Protection Agency notes that new technologies might be able to
produce ethanol from agricultural and industrial waste, such as scrap wood chips,
at a cost that’s competitive with today’s gasoline prices.

Capturing Wasted Methane From Landfills

  • A landfill is full of things people don't consider useful anymore. One group begs to differ. (Photo by Roberto Burgos S.)

The landfill is often seen as the end of the line… the burial ground of our trash. But one company says there’s still something to gain from that buried garbage.

The landfill is often seen as the end of the line… the burial ground of our
trash. But one company says there’s still something to gain from that buried
garbage. It’s planning to build a new plant to retrieve one final product from
all of our trash. The Great Lakes Radio Consortium’s Karen Kasler has the
story:


You probably don’t think of landfills as “green.” But Steve Wilburn does.
Wilburn is the president of FirmGreen. He says he knows different ways to
turn byproducts of landfills into useful energy.


First, capture the methane that’s produced when all that garbage stews
underground. Second, use it as fuel to generate electricity. Third, turn it into compressed gas for trucks. And finally, mix
it with soybean oil to make soy diesel.


Steve Wilburn says it’s an ambitious project.


“This is the first of its kind in the world. The Green Energy Center concept is
something I came up with about four years ago, and as we explored for ways to
implement it, we needed a centerpiece, a technology that was missing, and that
was to clean up the landfill gas in a very cost-effective way.”


FirmGreen is building what it calls its Green Energy Center right next to the
landfill in Columbus, Ohio. Mike Long is with the Solid Waste Authority of Central Ohio – SWACO for short. Long says right
now, there’s no practical use for the methane and carbon dioxide produced by the rotting garbage in the landfill.


“Currently, SWACO’s control technology is to have a flare where we burn off the
gases to keep it from getting up into the atmosphere. But the new technology,
we will take that gas and make it into energy and consumer products rather than
just simply burning it and exhausting it.”


Instead of burning those landfill gases, they’ll be redirected a small
electric generator operated by FirmGreen. The electricity will be sold back to
SWACO to power its main office and its fleet garage. That’ll start in just a
few months.


Later, FirmGreen will convert methane into compressed natural gas. That will
be used to fuel SWACO’s vehicles, which could save the waste authority an
estimated 100 thousand dollars a year.


FirmGreen’s President, Steve Wilburn says the final part of the project is the
real profit maker for his company: turning methanol into biodiesel.


“When we create
methanol, we then have the bridge to the hydrogen economy because ethanol is an
excellent hydrogen carrier. It’s also used in the manufacture and production of
biodiesel. Ohio is a large soybean producing state. So we’ll take our green
methanol and we’ll blend that with the soy oil and we’re going to create
biodiesel.”


When the FirmGreen biodiesel processing facility is up and running, it will
need 69 thousand acres of soybeans to produce 10 million gallons of biodiesel
annually. FirmGreen already has a contract with Mitsubishi Gas Chemical
Company to provide 6 million gallons of biodiesel a year. FirmGreen also hopes
to interest the growing hydrogen fuel cell industry.


“Biofuels” have their critics, who are concerned that it takes as much energy
or more energy to create biofuels than they produce. Mike Long at SWACO says
he’s heard that before, but it doesn’t apply to this project.


“The
energy is already here, and is being flared off right now at our landfill. There’s no recovery of the energy, no beneficial
use. So for those who argue that this process would be a consumer of energy, it’s not a net consumer, and right now, we’re wasting energy.”


Long and Wilburn point to statistics from the U.S. EPA. They says the data show
the Green Energy Center will have the same effect as reducing oil consumption by
more than twenty thousand barrels a year. They say that’s like taking 2,000 cars off the road.


Sam Spofforth is with the Central Ohio Clean Fuels Coalition. He says even
when factoring in the fuel used by trucks transporting the methanol to the
remote biodiesel processing facilities, the project still looks green to him.


“In terms of biodiesel, it’s about three point two energy units out for every one energy
unit in. What is even more exciting about this project – methane
gas is about twenty times as potent as a greenhouse gas as carbon dioxide. So the
fact that they’re using methane that would otherwise be vented into the air
makes the net emissions of those greenhouse gas even more positive.”


The Green Energy Center in Ohio is the first in the nation, but a second one
is planned to be built near Saint Louis, Missouri. With giant landfills venting
off methane in places around the country, if these two make money, it’s a
pretty sure bet others will be built in the near future.

This winter U.S. automakers have unveiled more environmentally friendly cars, SUVs, and
trucks. They include gas-electric hybrids, even hydrogen fuel cell powered vehicles. The new
models will reduce smog and other emissions and reduce our dependence on foreign oil. But a
cleaner domestic fuel already exists for diesel cars and trucks, and you can find it at most
restaurants. The Great Lakes Radio Consortium’s David Sommerstein profiles a man who brews
his own biodiesel from used vegetable oil:


Joe Rappa’s VolkSwagen Quantum looks like any older car. It’s a maroon station wagon with
180,000 miles on it. It’s got a diesel engine with the tell-tale diesel rattle.


(car starts)


But even though we’re inside an enclosed garage in an auto lab, there’s no black exhaust, no acrid
diesel smell. Instead, it smells like a kitchen.


“Some people say it smells like French Fries, some say it smells more like hamburgers on the
grill than anything else. But everyone smells something different with biodiesel.”


Rappa teaches automotive courses here at the State University of New York in Canton. He lives
120 miles away. Several times a week he commutes in this car powered by biodiesel – a fuel
made from used vegetable oil he collects from local restaurants. He says anyone with a diesel car
can do it themselves.


“It might be a bit unnerving at first because we’re so conditioned to put the same fuel in our car,
that y’know that you go make something in your garage and then go pour it in the tank of your
car goes against everything you’ve been ever taught for the last 20 years that you’ve been
driving.”


Joe Rappa has a mischievous smile when he talks about brewing his own fuel, especially with
most people worrying about the price of gas, the places our oil comes from, and what it does to
politics and the environment. But Rappa insists he’s not an environmentalist.


“I don’t consider myself a big polluter, either. I’m a tinkerer. I always have to fool around with
something. It’s funny, my dad always used to kid me from the time I was a little kid, ‘You’re not
happy unless you’re screwing around with something.’ My bicycle worked fine, I’d take it apart.”


As an adult, he bought a diesel car. One day, he started reading about biodiesel on the Internet.


“And the more I looked at it, the more I thought, that’s kind of silly, but I bet I could do that, and
got a hold of the chemicals and started fooling around and making mini-batches, and once I was
confident the mini-batches were actually biodiesel and something I can burn in an engine, I
started making bigger batches and putting the stuff in my car.”


Today Rappa spends Sundays in his garage brewing up to 120 gallons of it at a time. He’s
considered a leading expert on biodiesel bulletin boards on the Internet.


Most of the enthusiasts he e-mails with are environmentalists. They see biodiesel as a way to
reduce our reliance on foreign oil and clean up the choking exhaust cars and trucks belch out their
tailpipes. Rappa says biodiesel creates less than half the smog-causing emissions of regular
diesel.


“The particle emissions out of the tailpipe, 70% less simply by switching fuel, 70-80% less
hydrocarbon, 70-80% less carbon monoxide, those are some serious numbers.”


Nitrous oxide levels are a little higher, though. Those also contribute to smog. But for Rappa,
the big number is price. It costs him 54-cents a gallon to brew the stuff.


Rappa snaps on rubber gloves to show me how it’s done. Basically you mix methanol and lye to
make methoxide. Then you add the methoxide to the oil. The ratio depends on the amount of
animal fat in the vegetable oil, which you figure out through what’s called a titration, and the
amount of biodiesel you want to brew.


“Now we just add the methoxide to the vegetable oil.”


Rappa uses old Pepsi bottles for this demonstration and a wine carafe to hold the oil.


“Put our lid on there. Give it a shake. Immediately it turns to a milkshake consistency. And the
reaction only takes a couple seconds to take place. You mix it thoroughly and it’ll start to get
dark as my biodiesel starts to form.”


The result is honey-colored biodiesel. Glycerine – basically soap – settles on the bottom as a by-
product. Rappa cautions this takes practice. You have to boil the vegetable oil to remove any
water in it. You need to make sure you separate the biodiesel from the glycerine.


In fact, most people who use biodiesel in their cars buy it commercially. Their number is
growing. The National Biodiesel Board predicts biodiesel production will increase by 20 million
gallons this year. Most it is made from soybeans. Some producers use other vegetable oils. But
a U.S. Energy Department-funded study says there’s enough used vegetable oil and other waste
grease to produce 500 million gallons of biodiesel each year.


(sound up of driving)


That’s plenty to keep Joe Rappa’s car on the road and encourage others to join him.


“I still chuckle every time I pour in fuel I made in my garage in the tank of my car.”

Usda Running on Alternative Fuels

The Department of Agriculture is expanding its use of alternative fuels generated by farms. The Great Lakes Radio Consortium’s Lester Graham reports:

Transcript

The Department of Agriculture is expanding its use of alternative fuels generated by farms. The Great Lakes Radio Consortium’s Lester Graham reports.


The USDA is increasing the use of bio-diesel and ethanol. Bio-diesel is a fuel that can be made by refining natural oils such as animal fat, spent cooking oil or soy bean oil. Ethanol is a blend of gasoline and alcohol, usually derived from corn. USDA agencies such as the Forest Service will increase the use of the fuels in fleet vehicles, including cars, tractors, and even boats at agency offices across the nation. Donald Comis is a spokesperson for the Department of Ag.


“It’s a deliberate strategy of the whole federal government to have demonstration areas all over the country so that you won’t have to travel far to see a vehicle or operation like your own.”


While the USDA is promoting bio-diesel and ethanol, some environmental groups say the taxpayer subsidized fuels use too much energy to produce and only survive because of politics. For the Great Lakes Radio Consortium, this is Lester Graham.
