When Congress approved production
tax credits for renewable energy,
not every industry got the same
treatment. Lester Graham reports
biomass power is not getting the
subsidies that other alternative
energy sources get:
Biomass power – produced from organic waste such as wood chips, grass or stuff that would otherwise just be thrown away – got half the tax credit that wind and solar did. And, instead of the tax credit lasting ten years like the other renewable energy sectors, biomass power got five years.
Bob Cleaves is the president of the Biomass Power Association. He says that tax credit for biomass is now gone.
“And our industry, frankly, is in crisis at the moment because Congress has let expire existing production tax credits we were only given five years for and if those are not brought back to life, then I’m afraid we’re not going to be growing the baseline, we’re going to be losing the baseline.”
Cleaves says without the tax credit, some states will be at a disadvantage in meeting the federal government’s requirments for more electricity to come from renewable energy.

People fed up with hearing
about an energy crisis talk
about going off the grid.
In the US, the solution is
to install solar panels on
your roof or put up a wind
turbine. But a village in
Germany has taken a different
approach. In the final part
of our three-part series on
biofuels in Europe, Sadie
Babits explains:
The village of Juhnde sits between rolling farmland and woods. The first buildings went up more than a thousand years ago. It looks like a lot of German villages – narrow streets, terra cotta roofs, and a towering church steeple. But talk to anyone here and they’ll tell you Juhnde is no ordinary town. It’s the first community in Germany to be powered and heated by cow manure and grain.
“This is the biogas power station on this side.“
That’s Gerd Paffenholz. He’s lived here in Juhnde for 20 years. He volunteers to show visitors, like me, the village’s bio-energy plant.
“This is the wood heating system and what you don’t see is the network that deliver the hot water in the ground.”
Paffenholz stands on top of an underground storage tank. The liquid manure in here gets pumped over to a massive green tank. That’s the anerobic digester. There, micro-organisms have a hay day eating manure and grains supplied by farmers in Juhnde. The bacteria create biogas, which then gets combusted into heat and electricity. It’s pretty silent outside the power station but open the door…
(engine sound)
That’s the sound of 700 kilowatts of power being generated. The electricity gets sent to the public network. It provides this village of 750 people with renewable power. There’s an added bonus – energy that’s normally lost while making biogas gets captured and is used to heat water. That hot water gets delivered through a series of underground pipes to heat most of the homes in Juhnde.
The village’s bioenergy plant went live five years ago. The price tag? Nearly 8 million dollars. The money came through a government grant and from residents who each ponied up thousands of dollars to join the plant cooperative. The village has also cut its greenhouse gas emissions in half already meeting targets set by the European Union for 2050.
“It shows you what some wise investments and collective thinking can make happen.”
That’s Jim McMillan. He researches biofuels at the National Renewable Energy Laboratory in Boulder, Colorado. He says Juhnde has created an attractive model that could work in the Northern US and Canada where people are more remote and winters are long and hard.
“It’s a good model but Europe, I mean, they’re built out much more than we are and they are doing a lot more in building. They’re density of building, the size of their square foot of their homes are much more right size and so these solutions are easier to implement there than they are here I mean we have a lot more big homes that require a lot more heat.”
Our attitudes are different too. It took several years to get Juhnde’s residents to buy into the idea of going off the grid but now most everyone is on board. Here in the U.S. we’re a lot more individualistic. But McMillan still sees a lot of promise in what Juhnde accomplished.
“So one village is a good example but we need to apply it across the board.”
Other villages in Germany are building bio energy plants. In the U.S. a few towns are attempting parts of Juhnde’s efforts. Reynolds, Indiana replaced the town’s vehicle fleet with cars and trucks that run on bio fuel. It’s now working with a company to turn algae into power. And in Grand Marais, Minnesota, they want to build a central heating system for the town that burns wood chips from the local saw mill.

The US government is spending
millions of dollars to build bio-energy
plants. They’ll turn everything from
wood chips to algae into energy. But
these facilities are years behind what
they are already doing in Europe –
especially in Germany. In the first
part of our three-part series on biofuels
in Europe, Sadie Babits takes us to one
German plant that makes green energy
on a massive scale:
We’re in Eastern Germany where crews work on what looks like brew vats.
(construction sound)
These monster tanks remind me of vats for brewing beer, except these vats will brew energy from fermenting rye, manure and bacteria.
“Basically, we’re standing here in front of the biogas and bio fertilizer production area. The big fermenter is for the biogas production.”
Oliver Lutke is our tour guide. He’s really a chemical engineer for Verbio. The company is one of Germany’s largest commercial producers of biofuels. Lutke’s been involved in turning this ethanol facility into a plant that makes ethanol and biogas. That’s methane.
“We convert everything into energy by using biological processes. This combination biogas and bioethanol production plant isn’t existing in the world.”
That’s what Verbio claims anyway. The company buys grain from some four-thousand farmers in the region. The grain gets turned into biogas and ethanol. Verbio then turns the minerals from making these biofuels into fertilizer.
That goes back to the farmers for their crops.
“We’re closing the loop to the farmer converting all the carbon to energy and the minerals going back to the farmers as fertilizer which is growing the plants used to extract the energy.”
Lutke says the company has the technology to make this industrial sized plant profitable. That baffles skeptics because it costs a lot to make green energy. You have to buy the grain. And the actual process of turning that grain into fuel can be really inefficient. By the time you’ve made one gallon of biofuel, that gallon of oil is cheaper.
Jan Liebetrau isn’t convinced Verbio has the answer. He researches bioenergy and its potential in Germany.
“If you put lots of energy into the system and you get bioethanol you’re putting more energy in than you get out.”
So making bio ethanol costs energy, which defeats the whole purpose of producing it in the first place. Lutke doesn’t see it that way. He says Verbio has the technology to make biofuels without losing energy. And because the company’s process is more efficient, Lutke says they’ve cut down on greenhouse gas emissions.
“We emit 200,000 tons and the plants we are using will eat off 180,000 tons and that’s a closed cycle.”
It’s not perfect, but there’s less greenhouse gas being released than, say, from an oil refinery. Lutke is convinced bio energy will play a big role in cutting greenhouse gas emissions.
Germany, and Europe for that matter, have become leaders on this. Germany wants to be the first industrialized nation to be powered entirely by renewable energy – a goal Germany could reach by 2050, well ahead of the U.S.

Bio-diesel is supposed to make

But to make enough biodiesel on
the cheap, we’ll need to get more
oil out of soybeans. Shawn Allee says we could be one step
closer to fixing that:
Tom Clemente is a kind of true-believer in biodiesel. He studies plant biology at the University of Nebraska. Clemente says the problem is, we use pricey soy-bean oil to make biodiesel.
“The downside is there’s just not enough of the oil to really make a dent on petroleum.”
Clemente figures scientists can manipulate genes inside soy beans to boost oil content, but no one knew exactly where the genes are. Recently, though, scientists completed a big-picture map of soy’s basic genetic make-up. Clemente hopes that’ll speed up development of oily soy beans – just for biodiesel.
“Really getting a bio-based sustainable fuel from some sort of cropping system, the production’s going to have be really up there.”
Clemente hopes we get enough biodiesel to clean up the nation’s dirtiest vehicles, such as construction equipment and city buses.

California regulators want car fuels to come from sources that create fewer greenhouse gas emissions. That means corn-based ethanol will soon get a kind of penalty in California’s fuel market.
Environmental groups like the Natural Resources Defense Council say ethanol should be at a disadvantage. The NRDC’s Roland Hwang says when we grow corn for fuel, farmers overseas plant more corn.
“Someone’s going to cut down a rain forest or convert pasture land or grass land to grow more food. Unfortunately, converting that land will lead to very dramatic increases in global warming pollution.”
Hwang wants the ethanol industry to stop using food crops for fuel.
Ethanol makers are not taking California’s rules sitting down, though; they’ve gone to court. They argue more lenient federal rules on ethanol should trump California’s.
It can take a lot of water to make ethanol.

The ethanol industry and the government
want more ethanol to be produced. They
say the homegrown biofuel is a good way
to move away from foreign oil. But a new
government report says many ethanol
refineries are putting a strain on another
natural resource – water. Mark Brush has
more:
When you fuel up at the pump, chances are you’re putting ethanol into your car. Nearly half of the gasoline in the U.S. is blended with ethanol. And that’s likely to increase as they build more refineries.
But the Government Accountability Office says these ethanol refineries should consider local water resources before they build. It can take a lot of water to make ethanol.
Anu Mittel follows water resource issues for the Government Accountability Office:
“Many of them are being built in areas where they are relying on groundwater aquifers for their water supply and that could have a devastating effect on the local community that is also relying on that same water source for all of its other needs.”
Refineries built in those areas often rely on irrigated corn to make ethanol. So it means drawing millions of gallons of water just to make the ethanol at the refinery.
The smaller supply of cellulosic ethanol might mean the country uses less efficient ethanol from corn, or keeps using more
gasoline. (Photo courtesy of the National Renewable Energy Laboratory)
Cellulosic ethanol is supposed to

industry might provide just a trickle:
The fuel industry’s supposed to create 100 million gallons of cellulosic-ethanol next
year. But industry leaders say they might create just 12 million gallons.
Wes Bolsen is with Coskata. His company can create ethanol from wood chips and even
household trash. Bolsen says companies like his found some investment money – but the
financial crisis created delays.
“We’re building refineries – 300, 400 million dollar assets and that’s a lot of money
to come together. We’re two years delayed, the whole industry. We can’t open them
in 2010. Facilities will start opening in 2012.”
The federal government might have to shift mandates for cellulosic ethanol into the
future.
That could mean the country uses less efficient ethanol from corn, or keeps using more
gasoline.

Finding alternative fuel sources in our country involves looking at what nature has to
offer. In the West, they’re harnessing wind and solar energy. In the Heartland, it’s sweet
crops like corn. Susan Mittleman reports, in the South, they’re looking to their forests to
make cleaner, greener fuels:
Chuck Leavell plays keyboards for the Rolling Stones. But when he’s not on the road, he
spends his time on his plantation outside of Macon, Georgia, tending to some 2500 acres
of pine trees.
“This is our tree farm here.”
From this tranquil refuge of nature and wildlife, he sees these trees as a possible way to
reduce our dependency on foreign oil.
“The fact that we have such wonderful resources, our forest, and that we are
looking for new markets, gives us a lot of hope to be able to use our trees to make
energy products, whether its electricity or gasification processes or any matter of
liquid fuels.”
Cutting down trees and turning them into fuels might not seem like the greenest thing to
do.
But people like Jill Stuckey, insist it is.
Stuckey heads Georgia’s Innovative Center for Energy, and says there’s no better source
for clean fuel here, than the state’s 24-million acres of forest land.
“We grow pine trees like Iowa grows corn. And it’s a renewable source of energy.”
Stuckey says trees grow faster and are more accessible in Georgia than any place else in
the country.
“It’s a good thing. Because trees sequester carbon. And we harvest these trees and
plant new trees, so we’re continuously replenishing our supply.”
She says an acre of pine trees can yield about seven tons of biomass per year.
Biomass is basically any living thing that grows and then can be harvested.
And that stuff can be used to make ethanol, electricity, and bio-diesel.
(sound of a factory)
At a small factory down in Albany Georgia, that’s what John Tharpe is making here.
Tharpe is semi- retired electrical engineer, and has designed a machine that converts
pine-tree chips into bio-diesel. The fuel can be burned to power and heat homes and
businesses.
“We’re using biomass. We make an oil and a char and then we are also looking now
at making electrical energy. You can use it in any commercial burner, such as
steam, boilers, those types of things.”
He’s already begun selling his biodiesel technology to people around the world.
So, Tharpe is making for electricity and heat. Other companies are making plans to use
trees to run our cars.
Range Fuels is building the ‘first-of-its kind’ bio-fuels plant in Soperton Georgia – which
will convert wood chips into green transportation fuels, things like ethanol and methanol.
Ron Barmore is the company’s project development director.
He says their facility is designed to produce upward of 100-million gallons of fuel a year.
“Our belief is that we’ll be able to compete with fossil fuels, with oil prices in the 70-
80 dollar a barrel range. We think long term that’s a viable place to be.”
And long-term sustainability is what tree farmers and environmentalists like Chuck
Leavell are looking for, not just for green energy, but for other reasons as well.
“These trees, in the period we plant them and their growing, they’re cleaning our
air, our water, providing home and shelter for wildlife, that helps everyone.”
More than 100 companies are looking at ways to use Georgia’s trees, in some form or
another, to produce greener, cleaner energy.

One city’s new program is taking the mucky sink-clogging grease from restaurants and converting it into fuel for its fleet of vehicles. As David Gorn reports, it’s the first effort of its kind in the nation:
It’s 6 in the morning, and a San Francisco sewage treatment plant is already in full gear.
(sound of a truck motor)
Workers are unloading a tankful of used cooking oil from local restaurants.
(sound of a man shouting)
But soon they’ll also be picking up something a little nastier from restaurants.
“Brown grease is culled out, pumped out by grease haulers and taken out of the city, often to landfills.”
That’s Karri Ving, biofuels coordinator for the San Francisco Public Utilities Commission. She says, instead of carting that grease off to a garbage dump, it will now be converted into biofuel.
“That material, that food material, is what we’re going to condense into a putty that gets converted into road-worthy biodiesel.”
Ving says San Francisco expects to process about 10,000 gallons of the
stuff every day.

Julie Grant reports that means, when you fill up your car in those states, the gas won’t be quite as bad for the environment:
The partnering states want to reduce the amount greenhouse gases coming from car tailpipes.
Ian Bowles is Secretary of Energy with the Massachusetts Department of Environmental Protection.
He says the states would prefer that the federal government take the lead on this issue, but they’re doing what they can to limit carbon emissions from cars and trucks as soon as possible.
“If everyone waits and sits on their hands until there’s a global agreement, it’s going to take a long time to get anything done.”
Bowles expects the eleven-state agreement to spur investment into new types of ethanol and biofuels. And he says that will mean new jobs in science, engineering, and at fuel refineries.
“We’ll be creating a much bigger market for biofuels. Jobs will get created and greenhouse gasses will be cut.”
The states expect to have a legally binding agreement on the low carbon fuel standard by the end of the year.
