Zingst, Germany—"What an eyesore, huh?" the man standing next to me on the beach said, nodding in the direction of a little girl flying a kite. The man, in his mid-40s, seemed to enjoy my confusion. He waited a beat before pointing beyond the girl, far out into the Baltic Sea. "There," he said, smiling to make sure I understood his sarcasm. "The 'ugly' wind farm."
Staring hard, it was barely possible to make out the turbines on the horizon. Ten miles from shore, the Baltic 1 Wind Farm seemed as small and insubstantial as the scruffy grass along the coast. But, in fact, each of the nearly two dozen turbines is as tall as a 27-story building and has fiberglass epoxy blades nearly 150 feet long. Work has already begun on wind farms with even larger turbines that will generate twice the power of those at Baltic 1, enough to supply 250,000 households with electricity.
Wind turbines produce 10 times more electricity in Germany today than they did in 1999. What's even more remarkable is that this expansion is modest compared to the growth of solar power. In 1999, Germany had an installed solar capacity of 32 megawatts. In 2012, that figure was 30,000 megawatts—a nearly 1,000-fold increase in a nation that gets roughly as much sunlight as Alaska. On a sunny day that's as much electricity as 13 nuclear power plants would produce.

This is Chapter 2 of a six-part series on Germany's remarkable clean break with coal, oil and nuclear energy. Click to read Chapter 1Chapter 3Chapter 4Chapter 5 and Chapter 6. Or read it all now as a Kindle Single ebook on Amazon for 99 cents.

How did wind and solar power take off so fast and so dramatically in one of the world's largest industrialized economies? How did renewable energies of all kinds come to account for more than 25 percent of the power fed into Germany's grid—compared to just 6 percent in the United States?
The answer is as simple as that old cliché about real estate—the one about how everything depends on location, location, location. In the case of Germany's astonishing energy transformation, it's all about policy, policy, policy. Specifically, it's the Renewable Energy Act of 2000, known in Germany as the EEG.

Rainer Baake, one of the EEG's authors, sums up the task that members of the German parliament faced when designing the policy: "We had to transform the old system completely."
The EEG's goal was to replace coal- and nuclear-generated electricity with power from clean, renewable sources of energy: wind, biomass, solar, geothermal and small hydropower facilities. The target set by the law was one of the most ambitious in the world: By 2050, Germany would rely on renewable energy sources for 80 percent of its electricity. Opponents scorned the plan as "green delusions."

The law's supporters had several reasons for wanting to phase out coal and nuclear power. Burning coal adds tremendous amounts of carbon dioxide to the atmosphere, and nearly all Germans recognize climate change as a serious threat. Also, the country is running out of coal and Germans don't want to be dependent on foreign imports—the desire for energy independence is felt even more acutely in Germany than it is in the United States.

Gradually phasing out nuclear reactors made sense, too. Germans had been ambivalent about nuclear energy for decades, especially after the 1986 meltdown of a Soviet reactor in Chernobyl, Ukraine, sent radioactive clouds drifting across much of Europe. In addition to fears for their own safety, many argue that it is unethical to burden future generations with the radioactive waste that nuclear power produces.

There was a more immediate social goal behind the EEG as well: the democratization and decentralization of energy production.

"The solution to our energy problems, from nuclear to climate change, can't be a centralized one," Eva Stegen explained to me as she piloted us through the cloud-banked mountains of the Black Forest in her three-wheeled electric car. As communications director for EWS, Germany's first clean energy cooperative, Stegen had no doubt explained all of this many times, but she is so enthusiastic about the Energiewende that she answered my most basic questions as if she were hearing them for the first time.

"Einstein said that the way that leads into a catastrophe cannot be the way that leads out," she said, rounding a corner in the little, neon green car. "Centralized power is the problem. So we needed to find a new way. And that is what the EEG gave us."

Centralized power generation is such an entrenched part of the U.S. electrical system that most Americans just assume that the only way to get power is from a few large generating plants, usually owned by corporate utilities operating as monopolies.

Not in Germany. Decentralizing electricity was at the core of the Energiewende,Rainer Baake told me. If utilities had remained in control of electrical generation, renewable power would still be a novelty.

"Our big utilities completely ignored renewables," he explained. "In the beginning, the Energiewende was driven almost entirely by individuals. Over half of our renewable power is still produced by small operations."

Baake, who had been in the German Parliament, is no longer involved in party politics. Today he uses his political experience and his formal training as an economist to direct Agora Energiewende, a non-partisan organization that works with energy producers, consumers and large utilities to smooth Germany's new energy path.

The group is so new that when I talked with him in April 2012 he didn't have an office yet. We met in a borrowed break room in an old Berlin office building in what was once East Germany.
Germany's "Big Four" power companies opposed the new law, he explained. They declared that smaller producers were too unreliable and intermittent to power the grid efficiently. They insisted that an industrialized nation required what the old energy system delivered: a few massive power plants churning out electricity 24 hours a day.

"They said it would be technically unfeasible to get more than 4 percent of Germany's electricity from renewables," Baake recalled. He smiled. "Well, we just reached 20 percent." Six months later, that figure is over 25 percent.

Decentralization is one of keys to the Energiewende's success. It rewarded people who installed solar panels on their roofs, or invested in cooperatives that bought wind turbines, by paying them for the energy they produced.

As a member of the Green Party, the environment was one of Baake's chief concerns. Renewable energies are nearly carbon-free, and like most Germans he believes humans have a moral obligation to reverse climate change.

But the real key to getting the German public to embrace the Energiewende was based less on what was in people's hearts and more on what was in their wallets. This was accomplished by giving every German the legal right to generate power and sell it to the grid, through a provision known as the Feed-in Tariff, or FiT.

The FiT helped decentralize power generation by setting a guaranteed premium price paid to anyone—individual homeowners, groups of neighbors or large companies—who produces energy for the grid using renewable sources. Farmers were among the first to take advantage of this new right. Because wind turbines leave relatively small footprints on large fields, they gained a lucrative new source of income while maintaining the old one.

The government sets the amount of the renewable bonus, but it doesn't fund it. Ratepayers do, as part of a monthly surcharge that shows up on their utility bills. The average German household pays around $108 a month for electricity, with the renewable energy surcharge accounting for $11.50 of that amount. (By comparison, an equivalent U.S. household pays $110 per month for electricity.)
The FiT works better than direct government subsidies or tax credits, supporters say. Subsidies can soar or plunge after each election, so they often fail to provide the stability that businesses need. But the FiT largely protects investments in renewable energy from politics by giving producers a 20-year guarantee on the amount they'll receive for the electricity they generate. The size of this renewable energy bonus shrinks every year, adding incentive to get solar panels and other renewable power plants up and running as soon as possible.

According to Hans-Josef Fell, the chief architect of the 2000 renewable energy act, one concern in setting up the EEG was to make sure it didn't give foreign manufacturers an economic advantage over Germany's all-important export sector, which uses large amounts of electricity. That's why the EEG exempted "electricity intensive" businesses from paying the renewable energy surcharge.
The arrangement seemed to be working well until this year, when the number of companies slated to receive the exemption swelled from 813 to well over 2,000. The exempted companies consume nearly 20 percent of all electricity generated in Germany. In part to cover the cost of the additional exemptions, the government recently announced the surcharge for 2013 would be raised, adding an average of $5 per month to each household's bill. The result, as Deutsche Bank recently pointed out, is that average Germans "will effectively subsidize German industry in 2013 to the tune of at least $2.5 billion via their electricity bills."

Even without the hike in rates, however, the cost of electricity from all sources has been steadily rising in Germany, as it has the U.S. and most other countries. One-third of the increase over the last decade is attributable to the renewable energy surcharge, but two-thirds is caused by completely unrelated factors. In fact, renewable energy has driven down the wholesale price of electricity in Germany, allowing the companies that are exempt from sharing the cost of theEnergiewende to pay 15 percent less for electricity in 2012 than in the previous year.

There is a broad consensus in Germany that paying somewhat higher electric bills is a fair exchange for moving to a clean energy future, said Ursula Sladek, who founded the Schönau Power Supply, Germany's first green energy co-op. Her evidence is compelling: the co-op began selling renewable power to a handful of neighbors in her Black Forest village in 1998. Today it serves 130,000 households and small businesses throughout Germany.

Unlike in the United States, where most people get their electricity from a single utility, Germans are free to choose from more than 800 electric companies. The success of her co-op shows that Germans are willing to pay more for renewable power, Sladek once told a German reporter, adding, "People aren't as dumb as politicians and energy providers think."

Oregon project could turn wave energy into electricity




A computer-equipped buoy that aims to turn wave energy into usable electricity output is assembled at a Vancouver, Wash. plant. The buoy, one of several of myriad designs, will be released into the Pacific Ocean near Portland, Ore.

About a dozen buoys have been placed a few miles from the cost of Oregon to get energy from the waves/currents in the ocean for usable electricity. related website: http://www.oregonwave.org/

PORTLAND, Ore. - About 15 years ago, this environmentally conscious state with a fir tree on its license plates began pushing the idea of making renewable energy from the ocean waves that bob and swell on the Pacific horizon.
Then one of the first test-buoy generators, launched with great fanfare, promptly sank.
It was not a good start.
But time and technology turned the page, and now the first commercially licensed grid-connected wave-energy device in the nation, designed by a New Jersey company, Ocean Power Technologies, is in its final weeks of testing before a planned launch in October. The federal permit for up to 10 generators came last month, enough, the company says, to power about 1,000 homes. When engineers are satisfied that everything is ready, a barge will carry the 260-ton pioneer to its anchoring spot about two and a half miles offshore near the city of Reedsport, on the central coast.
"All eyes are on the OPT buoy," said Jason Busch, the executive director of the Oregon Wave Energy Trust, a nonprofit state-financed group that has spent $10 million in the last six years on scientific wave-energy research and grants, including more than $430,000 to Ocean Power Technologies alone. Making lots of electricity on the buoy and getting it to shore to turn on lights would be great, Busch said. Riding out the storm-tossed seas through winter? Priceless.
''It has to survive," he said.
Adding to the breath-holding nature of the moment, energy experts and state officials said, is that Oregon is also in the final stages of a long-term coastal mapping and planning project that is aiming to produce, by late this year or early next, a blueprint for where wave energy could be encouraged or discouraged based on potential conflicts with fishing, crabbing and other marine uses.
The project's leader, Paul Klarin, said wave technology is so new, compared to, say, wind energy, that the designs are like a curiosity shop — all over the place in creative thinking about how to get the energy contained in a wave into a wire in a way that is cost-effective and efficient.
''Some are on the seabed on the ocean floor, some are in the water column, some are sitting on the surface, some project up from the surface into the atmosphere, like wind — many different sizes, many different forms, many different footprints," said Klarin, the marine program coordinator at the Oregon Department of Land Conservation and Development. "There's no one-size-fits-all kind of plan."
Energy development groups around the world are closely watching what happens here, because success or failure with the first United States commercial license could affect the flow of private investment by bigger companies that have mostly stayed on the shore while smaller entrepreneurs struggled in the surf. Ocean Power Technologies also will be seeking money to build more generators.
''Wave energy is very expensive to develop, and they need to see that there is a potential worldwide," said Antonio Sarmento, a professor at Lisbon Technical University and the director of the Wave Energy Centre, a private nonprofit group based in Portugal. "In that sense, having the first commercial deployment in the U.S. is very, very positive."
Here in Oregon, the momentum of research appears to be increasing. Last month, the Northwest National Marine Renewable Energy Center — financed by the United States Department of Energy in collaboration with Oregon State University and the University of Washington — deployed one of the first public wave energy testing systems in the nation, called Ocean Sentinel, about two and a half hours from Portland, in Newport. The first device tested was a half-scale prototype from a New Zealand company.
Fishing industry lobbyists and lawyers worry that a surge of wave energy could repeat what happened when hydroelectricity came to the Pacific Northwest in a big way starting in the 1930s. Builders then did not think through the dense ecological web that nature had devised around the tens of millions of salmon — suddenly blocked from their inland spawning routes — that had over millenniums become a cornerstone species for everything from bears to birds.
"Our greatest concern is that they don't do what they did with dams — put a lot of them in the ocean and then just stand back and see what happens," said John Holloway, the secretary of Oregon Anglers, a political action committee for recreational fishing. "We're advocating a go-slow approach."
What has not changed is that the Pacific Northwest still has a siren song for wave-energy dreamers in the big, consistent rolling ocean swells that define offshore waters — and make many a boater seasick — from Northern California through Washington state.
''Wave energy is essentially an accumulation of wind energy," Charles F. Dunleavy, the chief executive at Ocean Power Technologies, said in a telephone interview. In the northern Pacific, he said, consistent winds fuel consistent waves, and the distance they travel in their rolling line creates a huge area of wave energy, or fetch, that a bobbing buoy can capture. Other places with good fetch include some areas off the coasts of Western Europe and South America.
But the project also hinges on squeezing out the tiniest of incremental efficiencies in tapping the waves as they come. On the Ocean Power Technologies buoy, which looks like a giant cannon stuffed with electronics, company engineers pursued an insight that sailors have known in their sea legs since the days of Odysseus: Every wave is different.
The onboard computer in each buoy, in communication with an array of small devices called wave riders that float farther out in the ocean, adapts, or "tunes," to each incoming wave, adjusting the way the giant internal shaft rides up and down as the swell passes through. The up-and-down motion of the shaft creates the electricity, which goes to shore through a seabed cable.
In a nod to environmental concerns, the buoy was redesigned to remove all hydraulic fluids, which some critics feared could contaminate the water in the event of an accident; rack-and-pinion gears now drive the mechanics.
The three anchoring tethers, said Michael G. Kelly, the vice president of operations at Ocean Power Technologies, were also built to withstand a 100-year storm, but also with enough redundancies that even if two anchors failed the third would be enough to keep the buoy in place.
