Some states have been looking at
new ways to get more renewable energy
on the grid. This year, California,
Vermont, and now Hawaii implemented
a German-style pricing model that pays
people for the green electricity they
generate. Ben Markus reports:

Hawaii imports fossil fuels – namely oil – to meet 90% of its energy needs –
including electricity.

“We’ve been saying for decades that this is foolish, and yet we haven’t changed. Well, now we’re
changing.”

Ted Peck is the state’s Energy Administrator. He says recent approval of
the new pricing model will help spark that change.

It offers a premium price for renewables. That makes it easier for solar and
wind companies to secure financing because they know what they’ll be
paid.

Mark Duda is president of the Hawaii Solar Energy Association. He says
it’s not as wide-open as the German model, but it will make a difference.

“Many of the key design elements went in the direction that the solar industry wanted, and so we’re
definitely pleased with that.”

The big sticking point is setting what will be paid for renewables. And some
are worried about how this will affect ratepayers.

Hawaii already has the highest energy prices in the nation.

Many European countries are taking
climate change seriously. Since
1990, Germany has slashed their carbon
emissions nearly 23%, emerging
as a leader in green energy. Conrad
Wilson explains the country’s transformation
to an alternative energy leader:

Nearly 20 years ago, Germany passed a law requiring utility companies to pay
homeowners more for creating green energy. Today that includes wind and
geothermal, but the big winner is solar.

Dr. Silke Karcher is a scientist at the German Ministry of Environment in Berlin.
She says the solar industry is growing, despite the lack of sun.

“One of the instruments, one of the legal instruments that we would really like to
export that has really been successful is the way that we’re supporting renewable
energies and electricity. We have a so-called ‘feed in tariff law,’ which mean that
wherever in Germany you produce renewable energy, you can feed it into the
grid and you get a specific price.”

And that policy has put Germany way ahead to the US. Even with all the rebates
and other recent incentives in the nation’s most pioneering green tech states, it
takes longer for homeowners in the US to pay off an investment in a solar array.

“What Germany does is that they say we’ll pay x amount of euros for every
kilowatt produced, period.”

That’s Jim Rarus, principal of InPower. It’s a Colorado-based solar installation
company. Rarus says rather than comparing renewable fuels to less expensive
fossil fuels, Germany accounts for the costs of pollution.

“They don’t compare certain technologies like solar, which obviously have a
higher cost basis, to other technologies like coal and natural gas, which have a
lower costs basis. So they’re paying a price that reflects the fact that it’s a little
more expensive to build a solar plant and allows the people that put it in to either
get their money back or to make a reasonable return.”

For homeowners investing in solar arrays in the US, the process can be
unpredictable and even frustrating. Johnny Weiss is executive director of Solar
Energy International. It’s a Colorado based nonprofit that trains people for
careers in the solar industry. He says the incentive system in the US is too
complex.

“Over here, it’s different and a more complicated system. We all have states that
are free to do their own incentive programs. We have incentives at the national
level. We have incentives at the local level. But the result is that it’s a bit
overwhelming for not just solar professionals, but the public as well. And it’s not a
consistent thing people can count on.”

Some communities in the US are trying out the European model. But the limited
government support in the US has driven competition as solar companies try to
make the energy source affordable. That’s something some fear isn’t happening
anymore in Germany.

Dr. Kurt Christian Scheel heads up the Department of Climate and Sustainable
Development for the German private industry association. Scheel worries that
government incentives have stifled innovation.

“I mean, let’s put it this way. Whoever produces solar panels in Germany has a
safe earning and no motivation in anyway to, and not enough competition to,
innovate and to make things better.”

But even if in the long-term some feel a feed-in tariff slows innovation and
growth, it’s proven that in a short period of time it can drive energy consumers to
become producers.

A Spark in Your Step

When you think about alternative energy
sources, you probably don’t include people on your
list. But Ann Murray reports that scientists are
tapping into bionic people power:

Today, we really do have bionic technology.

(Opening of the “Six Million Dollar Man”) “Gentleman, we can rebuild him. We have the technology.”

Okay, maybe not to turn you into
the Six Million Dollar Man. But how about a mobile power plant?

Let’s start with the back story.

About 15 years ago, a couple of young
scientists, Doug Weber and Max Donelan, worked together. Donelan wrote
his grad school dissertation on the energy people create when they walk.
He asked Weber, now a biomedical engineer at the University of
Pittsburgh, to run with his idea.

“He approached me with the idea of building a wearable device that could actually harvest
that energy. And not only generate electricity but potentially make it easier
to walk.”

Weber and Donelan put together a rough prototype in his garage. A lab
tested version of their early demo was just published in the journal Science.
The bionic gizmo looks pretty much like a knee brace with a power pack
attached. Weber calls up a video on YouTube to show me how it works. On
the screen, a guy with a brace on each leg is walking on a treadmill.

“With each step he takes on the treadmill power is generated when the
knee is swinging in extension. It’s during that extension phase that we turn
on the generator and as the traces below the video show, generate large
peaks in power.”

Those peaks in power show up as the hamstring muscle “brakes” to keep
the leg from going too far forward. That’s when the bionic brace kicks in. It
grabs that potentially wasted energy and turns it into electricity.

The brace can crank up to 20 watts with each step. That means ten
minutes of walking can power a laptop for a half hour. No other lightweight
people-powered generator can top that.

Yad Garcha’s betting that people
will be intrigued. He’s the CEO of Bionic Power, a company formed to
market the brace. With some product tweaking, he envisions a world of
alternative energy possibilities. Especially for people who have to depend
on batteries or don’t have much access to electricity. His list includes
millions of people in developing countries, amputees, and soldiers.

“It is a green product primarily for the military because of the number of
batteries that they throw away.”

Garcha says, for example, Canadian soldiers carry up to 20 pounds of
disposable batteries.

“And these throw-away batteries cost a lot of money for them to get them into the
theatre or wherever they’re doing their fighting.”

Garcha’s already been talking to Canadian military reps about field tests.
But the brace probably won’t be ready for another year or two. The
prototype still needs to be quieter, lighter, and more efficient before it makes
its way into the hands – or rather, the legs – of consumers. Better move over
Steve Austin!

Using Dams to Make Hydrogen

Across rural America, there are old dams and
millponds sitting unused. A century ago, they provided
vital hydro-power for local industry. But many of them
were shut down as big power companies offered more and
cheaper power. Now, one community wants to use its
hydro-dam to power a hydrogen making facility. Jacob

Across rural America, there are old dams and
millponds sitting unused. A century ago, they provided
vital hydro-power for local industry. But many of them
were shut down as big power companies offered more and
cheaper power. Now, one community wants to use its
hydro-dam to power a hydrogen making facility. Jacob
Resneck reports:

(rushing water noise)

We’re standing beside an old dam next to a public area still known as Power Station Park.

“Back in the 1800s, where we’re standing now was a sawmill.”

Mayor Jamie Rogers is the mayor of Lake Placid, New York.

Two dams on this river create Mill Pond.

“As you look to your left, that was the old turbine house. It was one of two
turbines in the community that generated power for the village.”

After the massive hydro development in the late 1950s, Lake Placid’s hydro-electric turbines were
removed in favor of cheaper imported power.

Now the village is working on a project to again harness this local energy source. But this time it won’t
be for conventional electricity.

“We’d be generating power to start electrolyzing water to create hydrogen.”

Electricity from the dam would be used to extract hydrogen from the water. The hydrogen would then
be stored in high pressure tanks. The fuel could be used to operate vehicles without emitting any
greenhouse gases.

The researcher behind the Lake Placid proposal is Richard Greeley. He’s a former professor who’s
worked on other cutting edge energy projects.

“You use air from the atmosphere on one side and hydrogen on the other and they combine on the
electrode and it forms water and electricity.”

Greeley’s founded a company called Aqua Green Electric Energy. He hopes to develop local sources
for powering hydrogen fuel cells.

“This turbine set up I have could fit on any dam. Why you can renew it and generate electric power again from any number of dams, big, small,
little – any size. So, I’m thinking this whole feature can be duplicated once we show everyone that this thing works.”

The project is expected to cost $1.5 million dollars. The Village of Lake Placid won’t spend local tax money,
but plans to try to get state and federal dollars to pay for the project.

It’s expected to take at least 18 months to build. If it is built, it’s believed to be the first of its kind in the
country.

This project won’t be a money maker. The amount of hydrogen that could be produced would be at
most, about 25 kilograms a day – the equivelant of about 25 gallons of gasoline.

Eventually, local production facilities could spring up all over the country. Daniel Sperling is director
of the Institute of Transportation Studies at the University of California, Davis. He says as the sun sets
on the era of cheap oil, the nation and the world will have to start making other arrangements.

“It’s becoming increasingly urgent to reduce the amount of oil we use and to reduce the amount of
greenhouse uses. And in both cases hydrogen has great potential. Many people think that in 30 or 40
years it will be the dominant fuel source for vehicles, and for other uses as well.”

A 1998 survey by the U.S. Department of Energy found 212 untapped sites with significant hydro-
electric potential. That’s in the state of New York alone.

Lake Placid Mayor Jamie Rogers says all that unused power could eventually add up, cutting total
greenhouse emissions.

“If you look at small dams like this across the Northeast, across this state and probably across this
country, there’s a lot of potential to generate hydrogen fuel on sites from existing dams that are already in place.”

And he hopes his town is the first to show that it can be done.
