Storehouses for Solar Energy Can Step In When the Sun Goes Down
By MATTHEW L. WALD
If solar energy is eventually going to matter— that is, generate a significant portion of the nation’s electricity — the industry must overcome a major stumbling block, experts say: finding a way to store it for use when the sun isn’t shining.
That challenge seems to be creating an opening for a different form of power, solar thermal, which makes electricity by using the sun’s heat to boil water. The water can be used to heat salt that stores the energy until later, when the sun dips and households power up their appliances and air-conditioning at peak demand hours in the summer.
Two California companies are planning to deploy the storage technology: SolarReserve, which is building a plant in the Nevada desert scheduled to start up next year, and BrightSource, which plans three plants in California that would begin operating in 2016 and 2017. Together, the four projects will be capable of powering tens of thousand of households throughout a summer evening.
Whether the technology will be widely adopted remains to be seen, but companies like Google, Chevron and Good Energies are investing in it, and the utilities NV Energy and Southern California Edison have signed long-term contracts to buy power from these radically different new power plants.
One crucial role of the plants will be complementing solar panels, which produce electricity directly from sunlight. When the panels ramp down at dusk or on cloudy days, the plants will crank up, drawing on the stored thermal energy.
That job will become more important if photovoltaic panels, which have plunged in price lately, become even cheaper and sprout on millions of rooftops. As the grid starts depending more heavily on solar panels or wind turbines, it will need other energy sources that can step in quickly to balance the system — preferably ones classified as renewable.
Most utilities are trying to generate as many kilowatt-hours of renewable energy as they can to meet stiffer state requirements on incorporating more alternative energy, said Kevin B. Smith, the chief executive of SolarReserve.
“As we move forward, we’ll get more and more traction with the fact we can provide more capacity,” Mr. Smith said, referring to his company’s storage technology.
The Energy Department seems to agree: in September it gave SolarReserve a $737 million loan guarantee for its project in Nevada. The plant will generate 110 megawatts at peak and store enough heat to run for eight to 10 hours when the sun is not shining.
The public’s view on loan guarantees for solar projects has soured somewhat since the bankruptcy of Solyndra, a California company that received a $535 million loan guarantee to build a factory to make solar panels — only to see the market for the modules crash.
But the outlook has always been clearer for companies that make electricity, which, unlike solar modules, is generally presold by contract.
Technical details of the SolarReserve and BrightSource plants vary slightly, but both will use thousands of computer-operated poster-size mirrors aiming sunlight at a tower that absorbs it as heat.
SolarReserve absorbs the heat in molten salt, which can be used immediately to boil water, generating steam that turns a conventional turbine and generator. Hot salt can also be used to retain the heat for many hours for later use. BrightSource heats water that can be used immediately as steam or to heat salt for storage.
The plants rely on salt because it can store far more heat than water can. But once molten, it must be kept that way or it will freeze to a solid in part of the plant where it will be difficult to melt again. “You’ve made a commitment to those salt molecules,” said John Woolard, the chief executive of BrightSource.
The technology is not complicated, but the economics are.
The simplest, least expensive path for solar thermal is to turn the heat into electricity immediately. But the companies are a bit like the farmer who harvests the grain and stores it in a silo rather than shipping it straight to market on the expectation that prices will be higher later. They are betting that in revenue terms, the hour at which the energy is delivered will be more important than the amount generated.
The notion is that widespread adoption of solar panels — whether on rooftops or in giant arrays in the desert — will change the hours at which prices are highest.
Today, electricity prices usually peak in the late afternoon and evening on hot summer days. “Photovoltaic panels will do a pretty good job of chopping that peak” in the late afternoon, said Paul Denholm, a solar specialist at the National Renewable Energy Laboratory in Boulder, Colo.
In other words, the new price peak will be pushed to later in the day, to just before and after sunset, when solar photovoltaic production is small or nonexistent, he and other experts say.
Mr. Woolard said the chief goal of the new plants would be to produce electricity when the utilities need it most. “We’re optimizing around what is important for different times for the utilities,” he said.
His company’s contract with Southern California Edison still requires approval by California regulators.
Adding storage capacity helps keep the air-conditioners humming when solar panels are not producing, but there are other financial benefits.
The equipment that makes electricity from steam is the most expensive part of a solar thermal system, but if it is connected to storage technology, it can run almost twice as many hours as a plant without storage. That means the unit cost of electricity drops.
Another has to do with the arcane economics of electricity. A utility must assure a supply of electricity in two forms: energy and capacity. The difference has never meant much to most consumers, who directly pay only for energy, as measured in kilowatt-hours.
But capacity, the dependable ability to produce power, is becoming more important as renewable energy forms a larger and larger part of the grid.
Wind and sun provide a lot of energy but not much capacity. Today, backup capacity for wind and solar power comes in the form of expensive gas-fired generators, which sit idle most of the year but operate when the wind stops blowing or the sun stops shining.
Storage could cut costs by 4 cents a kilowatt-hour, Mr. Denholm calculates — a considerable benefit for a commodity that retails for an average of 11 cents. A big part of the savings is not having to build the gas-fired generators for backup.
For competitive reasons, neither BrightSource nor SolarReserve would discuss capital costs. But Mr. Smith of SolarReserve said that the storage technology amounted to less than 5 percent of capital costs. For BrightSource, Southern California Edison was willing to pay extra for a plant that could deliver when the sun was not shining.
The success of any given project may depend on the particular details, but other experts agree that a market is opening for plants with storage capacity. A study completed in July by Navigant Consulting, Sandia National Laboratories and Pacific Northwest Laboratory on the potential effects of adding large amounts of photovoltaic energy to NV Energy’s portfolio found that to integrate the new power sources, the utility would need more standby generation.
NV Energy would also need generation whose output could be adjusted over very short intervals to compensate for variability in solar photovoltaic production, the report suggested. The solar thermal storage system is designed to meet exactly those needs.

Darker Nights as Some Cities Turn Off the Lights
By MONICA DAVEY
HIGHLAND PARK, Mich. — When the sun sets in this small city, its neighborhoods seem to vanish.
In a deal to save money, two-thirds of the streetlights were yanked from the ground and hauled away this year, and the resulting darkness is a look that is familiar in the wide open cornfields of Iowa but not here, in a struggling community surrounded on nearly all sides by Detroit.
Parents say they now worry more about allowing their children to walk to school early in the morning. Motorists complain that they often cannot see pedestrians until headlights — and cars — are right upon them. Some residents say they are reshaping their lives to fit the hours of daylight, as the members of the Rev. D. Alexander Bullock’s church did recently when they urged him to move up Saturday Bible study to 4 p.m. from the usual 7 p.m.
“It’s just too dark,” said Mr. Bullock, of Greater St. Matthew Baptist Church. “I come out of the church, and I can’t see what’s in front of me. What happened to our streetlights is what happens when politicians lose hope. All kinds of crazy decisions get made, and citizens lose faith in the process.”
Cities around the nation, grappling with what is expected to be a fifth consecutive year of declining revenues and having exhausted the predictable budget trims, are increasingly considering something that would once have been untouchable: the lights.
Highland Park’s circumstances are extreme; with financial woes so deep and long term, it has extinguished all but 500 streetlights in a city accustomed to 1,600, utility company officials say. But similar efforts have played out in dozens of towns and cities, like Myrtle Creek, Ore., Clintonville, Wis., Brainerd, Minn., Santa Rosa, Calif., and Rockford, Ill.
What distinguishes these latest austerity measures is how noticeable they are to ordinary residents. If health care cuts, pay cuts, layoffs and furloughs — and even limits on enforcing building codes or maintaining parks — are most apparent to the people inside city halls, everyone notices when his streetlights go dark (and some cities, like Colorado Springs, where the issue boiled over, have already resumed some lighting when revenues allowed).
Turning off the lights has drawn grumpy crowds to city council meetings, stirred jealousy among neighborhoods and neighbors, and set off conversations about crime.
“I go around town, and even I think some areas seem a little darker than they should be,” said Tim Hanson, the public works director in Rockford, where officials turned off 2,300 of the city’s 14,000 lights. “It was not anything that I wanted to do, and it was nothing that the mayor or aldermen wanted to do, but it’s like your own budget at home — we can’t afford this anymore.”
Here in Highland Park, that had been true for a while. Over a matter of years, the city accumulated a debt of about $4 million to DTE Energy, the utility company. The city was paying less than half of its $60,000 monthly bill for an antiquated lighting system that was costly to maintain. So the company and city struck a deal. The company could turn off and take away 1,300 of the city’s lights, add 200 lights in strategic locations, and the debt would be forgiven, said Scott Simons, a spokesman for DTE.
The result in this 2.9-square-mile city feels like this: Lights are still abundant along Woodward Avenue, the crowded commercial strip. But a block away, along the quieter, residential streets, lights now remain mostly at intersections. Long stretches of blocks are dark, silhouettes of people are barely visible and potholes appear suddenly beneath tires.
Some people here say they learned of the plans this fall only when a truck pulled up outside their homes and workers began pulling the poles from the ground. (Though the added step of removing the lights — not just turning them off — seemed an affront to residents, company officials said it had to be done for liability reasons and to avoid continuing reports of power failure and the risk of metal theft.)
“The people were basically left in the dark,” said DeAndre Windom, who was elected mayor in November. He said the disappearing streetlights were the top concern of residents as he campaigned door to door.
“When you come through at night, it’s scary; you have to wonder if anyone is lurking around waiting to catch you off your guard,” said Juanita Kennedy, 65, who said she had installed a home security system and undergone training to carry a handgun in the weeks since workmen carried away the streetlight in front of her house. “I don’t go out to get gas at night. I don’t run to any stores. I try to do everything in the daytime and to be back before night falls.”
Highland Park, home of Henry Ford’s first moving assembly line, was once a well-off enclave of 50,000 residents. Ford left long ago, and Chrysler’s corporate headquartersmoved away in the 1990s. Now it has fewer than 12,000 residents — half the size it was just 20 years ago.
So for this city, a shrunken tax base and financial crisis have been long in the making, and the recent national downturn has only made matters worse. More than 42 percent of Highland Park’s residents live in poverty, unemployment is high and the median income here is nearly $30,000 below that of the state.
“To understand our street lighting situation is to understand the wealth that Highland Park once had; it was a situation where we had the best of almost everything and an abundance of lights,” said Rodney Patrick, whose father insisted on moving his family to Highland Park in the early 1950s because of its advantages — its status, in his words, as the shining city on the hill. “But we don’t have the residents to have the luxuries we had when we were a city of 50,000.”
If the outcome seems imperfect to many residents, not everyone views it as dire. “The lights are not out in Highland Park,” said Mr. Patrick, who serves on the City Council. “We’ve had a reduction, a responsible reduction.”
It is too soon to judge whether the lights have affected safety here. Officials from other communities and studies on the question of streetlights and crime draw mixed conclusions.

Frank Lloyd Wright: An Eco Visionary Before Green Became The Rage
An exhibit at the Phoenix Art Museum tries to bill Wright's "organic architecture” as a predecessor to the environmentally minded design of today.
One imagines that Frank Lloyd Wright, America’s most famous architect, would’ve laughed mightily at the suggestion that he is linked to the environmentally minded architects who litter the profession nowadays. They’re just so earnest the way they like to talk about their green roofs and their fancy solar panels and their taste for group work and collaboration. Whereas FLW liked to... well,he liked to do other things.
Yet, as a new exhibit at the Phoenix Art Museum tries to show, Wright’s signature “organic architecture” was a powerful predecessor to today’s sustainable-design movement. You see it in everything from Fallingwater in Pennsylvania to Taliesin West in Arizona and many of the lesser-known projects in between: “Wright’s concerns with materials, efficient use of space, sustainable manufacturing, attention to local environment and use of natural light mirror those of contemporary architects worldwide,” James Ballinger, director of the Phoenix Art Museum, says. “This exhibition provides an exciting forum for which Wright’s work can be re-examined and applied to concerns of the day.”
That seems to ring particularly true in Arizona, where Wright designed more than a dozen buildings. But looking out over the state's mind-numbing landscape of highways and tract houses, you wish architects drew on his ideas a little more.
Frank Lloyd Wright: Organic Architecture for the 21st Centuryruns through April 29. More info here.

Groundbreaking set for farming, energy center in Highland Park

GREEN-SMART House
Twine, A Tiny Gizmo That Holds The Internet's Future
"In the future, your house will send you a text message to warn you that your basement is flooding." Sounds like the kind of hooey you only hear in those fantastical "future of..." videos, doesn't it? Not anymore. Two MIT Media Lab graduates have created a "2.5-inch chunk of the future" called Twine that does exactly that, and more, and is available right now.
Well, not quite: it will be available in early 2012, thanks to its wildly successful Kickstarter campaign. And the best part about it, the part that surely made that fundraising surge to over $170,000? With Twine, you can make that future magic happen without any coding skills at all, right out of the box.
It's "the simplest way to get the objects in your life tweeting or emailing."Here's the basic idea behind Twine: software and physical stuff should be friends. You can program webpages, data, all kinds of apps to do whatever you want them to--and even use awesome tools like IFTTT.com to hack them together without knowing how to code. But making that software talk to stuff in the real world--especially stuff that's just laying around your house, and not pre-designed to be a "smart product"--takes PhD-level skills. And that, according to Twine creators David Carr and John Kestner, is just plain wrong.
Twine is a small slab of grey plastic that hides that PhD's worth of engineering magic--a bunch of internal and external sensors and a wi-fi hub--"the simplest possible way to get the objects in your life texting, tweeting or emailing," in Carr and Kestner's words. To create the aforementioned "house that alerts you when the basement floods," just plunk your Twine in the basement where its built-in moisture sensor will get wet if there's a flood. (And make sure it can still connect to your home wi-fi signal.) Then head to Twine's companion webapp, Spool, and create a simple rule-based program: "if Twine gets wet, send me a text message." (Yep, the "programming language" is actually that simple.) And blammo, that's it. You now have a "smart" house.
Carr and Kestner created a completely ingenious incentive to send their Kickstarter ask over the moon: for every $10,000 they received in pledges, they promised to build in another sensor to Twine's repertoire. Out of the box, Twine can sense temperature, motion, moisture, and magnetism; if Carr and Kestner keep their promise, Twine will ship with thirteen additional sensors, all controllable and programmable from the elegantly simple Spool web interface. That should be enough built-in "smart product" power to handmake a personalized version of Ericsson's phony super-home, but in real life. Not bad for a couple of guys working in their spare time.
Greenfield's!

To grow urban farms, give Detroit local control
Urban farming can redeem at least some of Detroit’s more than 40 square miles of vacant land — nearly a third of the city — for productive use. But those efforts won’t move ahead until Michigan’s largest city can use local control to protect its residents and neighborhoods. That’s why legislators ought to approve a soon-to-be-introduced bill — cosponsored by state Sens. Virgil Smith, D-Detroit, and Joe Hune, R-Hamburg Township — that would secure the city’s right to regulate agriculture within its borders.Sunday, December 4, 2011
