Big Bucks for Big Solar [Green Wombat]

Monday, January 28th, 2008

Israeli solar power plant developer Solel announced Monday it has scored $105 million in funding from London-based investment firm Ecofin -- yet another sign that the market for large-scale solar energy projects is reaching critical mass.

Solel last July signed the world's largest solar power deal when it agreed to supply California utility PG&E (PCG) with 553 megawatts of green electricity to be produced by a massive solar thermal power plant to be built in the Mojave Desert. The company's solar trough technology is also used in nine solar power plants (photo above) that were built in the Southern California desert in the 1980s. (In a solar trough power plant, long rows of parabolic mirrors focus the sun's rays on tubes of liquid suspended over the arrays to create steam that drives an electricity-generating turbine.)

Raising $105 million is impressive and it's certainly a big number. But given that a 500-megawatt solar power plant can easily cost $1 billion or more to build, it's a relative drop in the bucket. However, it will allow Solel to move forward with the project and line up project financing for the PG&E plant while it negotiates more deals with other utilities -- it won't say which, but likely candidates are Southern California Edison (EIX) and San Diego Gas & Electric (SRE).

Competitors BrightSource Energy and Ausra have solar power plant applications before the California Energy Commission and have signed or are negotiating power purchase agreements with PG&E.

"Everyone is realizing that the market is there for thousands of megawatts of peaking power," Solel CEO Avi Brenmiller recently told Green Wombat. "As time goes by we see energy prices rising and utilities are focusing their efforts to get solar thermal power because this is the right solution in the southwest United States."

The Ecofin investment in Solel is notable also given the uncertainty surrounding solar power at the moment due to Congress' failure to extend the solar investment tax credit in the recently enacted energy bill. The 30 percent credit is considered crucial to help solar energy companies secure financing for power plants and achieve economies of scale. The tax credit expires at the end of 2008 but solar energy proponents and their allies on Wall Street say they're confident that Congress will take up legislation this session to extend it for as long as eight years.

Clock ticking on crucial solar investment tax credit [Green Wombat]

Tuesday, January 22nd, 2008

When President Bushed signed the energy bill into law last month, much was made of the legislation’s mandate that automakers dramatically boost the fuel efficiency of their fleets. Less noticed was that the bill dropped a provision that would have extended the solar investment tax credit — a measure viewed as essential to transforming solar energy from a niche business into a multi billion-dollar industry that can generate gigawatts of greenhouse gas-free electricity.

The timing couldn’t be worse. With the current solar credit set to sunset, as it were, at the end of 2008, Big Solar is at at a tipping point: Utilities and renewable energy companies are in the midst of negotiating massive megawatt power purchase deals whose financing depends on the 30 percent investment tax credit, or ITC.

“I think there is a major concern that this will stall all the beneficiaries of the ITC,” said Joshua Bar-Lev, vice president for regulatory affairs for solar power plant developer BrightSource Energy. The Oakland, Calif.-based startup is negotiating a 500-megawatt agreement with California utility PG&E and is proceeding with plans to build a 400-megawatt solar thermal power station on the Nevada border (artist rendering above).

Solar energy companies, utilities like PG&E (PCG) and Edison International (EIX) as well as financiers such as Morgan Stanley (MS) and GE Energy Financial Services (GE), had pushed for an eight-year extension of the investment tax credit to give Big Solar projects enough time to get off the ground and start to achieve economies of scale. The provision also would have allowed utilities to claim the credit for solar projects they build. The measure drew support from both sides of the aisle in Congress but died — by one vote in the Senate — when Bush threatened to veto the energy bill because the solar tax credit would be financed by repealing previous tax breaks given to Big Oil.

“The Congressional leadership is very strong in their support of the ITC; they will put this on the table In 2008,” said Chris O’Brien, a Sharp Solar executive and chairman of the Solar Energy Industries Association, in an e-mail. “The solar industry will continue to contact legislators in key states.”

House Speaker Nancy Pelosi and the Democratic leadership in the Senate have pledged to re-introduce renewable energy tax credit legislation this session. “Speaker Pelosi has said repeatedly that she hopes to address that this year,” Drew Hammill, a spokesman for Pelosi, told Green Wombat. “We’re just getting started but there’s bipartisan support for the tax credit.”

Publicly, at least, no one in the solar industry will say that the uncertainty over the tax credit is affecting planned projects. “Our expectation is that there will be another tax bill that will address this issue,” said Kevin Walsh, managing director of the renewable energy group at GE Energy Financial Services. “We’re working on a number of [solar thermal] deals but it’s too early to disclose them.”

In recent months, PG&E has signed deals for more than a gigawatt of electricity — enough to light more than 750,000 homes — with solar power plant developers. Such power purchase agreements can take more than a year to hammer out and the permitting and construction of a solar power station can take another three to five years.

"We’re continuing to move forward with negotiations and with contracts that have already been signed, but certainly the absence of the ITC could potentially impact future projects,” said PG&E spokesman Keely Wachs. “Without the credit, it does increase the cost of that energy and of course it also sends a very clear market signal as to our country’s energy priorities.”

Silicon Valley solar startup Ausra is building a 177-megawatt solar power plant on the Central California coast to supply electricity to PG&E and is pursuing deals with Florida’s FPL (FPL) and other utilities.

“Just like any business, the solar industry prefers a predictable system for the future,” wrote Holly Gordon, Ausra’s director of regulatory and legislative affairs, in an e-mail. “It will be more difficult to plan for our projects while the situation remains uncertain. While we are currently seeing excellent demand for solar energy at market prices, we need a long term extension of the renewable energy tax credits to ensure market stability and investor confidence as the market continues to grow.”

The hard side of Mister Softie [Netly News]

Friday, January 18th, 2008

Ah, Microsoft. Nothing gets the knickers of Silicon Valley startup guys more twisted than signs that the world's largest software company is over-reaching again.

The latest outrage? Some of my friends at the Valley's best-known social networks and Web 2.0 companies are privately grousing that emissaries from Redmond are trying to "strong-arm" (their term) startups into giving special treatment to Messenger, Microsoft's (MSFT) answer to AIM and other instant messaging programs. The problem typically arises when a social network, say, offers its users the ability to import the list of contacts they've accumulated on Microsoft Hotmail.

Since the summer, my friends tell me, Mister Softie has been sending cease-and-desist letters to startups that try to do this. These nastygrams are typically followed up by a meeting with Microsoft reps, who then try a couple different approaches to get the startup to integrate Messenger into their service.

If the company wants to offer other IM services (from Yahoo, Google or AOL, say), Messenger must get top billing. And if the startup wants to offer any other IM service, it must pay Microsoft 25 cents a user per year for a site license.

If, however, the startup decides to use Messenger exclusively, the licensing "fee will be discounted 100 percent."

Such a deal!

Or not. The standard Microsoft term sheet being shown around the Valley also instructs  startups that if they want to offer search at any point in the future, they must agree "to negotiate in good faith for a period of sixty days exclusively with Microsoft on the terms under which Microsoft may provide such search service functionality..."

Naturally–and no one is complaining this is unfair—Microsoft also demands reciprocity of contacts. They say, in effect, we'll show you our Hotmail contacts, but you have to let your users share theirs when they sign up for Microsoft's Windows Live services.

None of the folks I spoke to agreed to talk on the record for fear of reprisals. So I will refrain from blind quoting some of their more incendiary remarks. Well, all but one: "This is a great example of why Google is the leader in the Net ecosystem and Microsoft is not," an angry entrepreneur (who does not work for Google) told me. "Microsoft is the anti-data-portability company."

Google (GOOG) and Yahoo (YHOO) routinely allow users to take their contacts with them when they join new social networks. So why doesn't Microsoft? Just who owns that data anyway?

I asked Brian Hall, general manager for Windows Live. "We want the user to be in control of their stuff," he told me. "We believe strongly that it's the user's data, it’s the user's choice."

Hall said he was unaware of any Messenger tie-in being a part of a signed contract, but didn't rule out the possibility. "I don't know of any contract we've signed that has those terms," he said, pointing out that the term sheets that are being passed around merely represent what Microsoft wants—not what it will ultimately get in each instance.

Aside, that is, from the social network Bebo, which in August announced an alliance with Microsoft that would bring Messenger in house for its users. In exchange, Bebo and Windows Live users are now able to exchange contact information to invite their friends to their respective services. (Hmmm, will Facebook—in which Microsoft is a minority investor—be next to make Messenger it's official IM client?)

Hall did say that in situations where Microsoft was dealing with a tiny company with few users, Redmond might be looking for a more favorable deal simply because the exchange of contact lists was so lopsided. "Let's say you are a startup and we offer to do a reciprocity deal where you can access contacts for our 410 million [Hotmail] users and I have access to your zero users," he said, noting that it took Microsoft 12 years to amass its enormous user database. Why should it simply allow that data to flow in one direction, without getting a little something back?

But wait a second. If I'm a Hotmail user, aren't all the contacts I amass mine? Can't I take my friends with me?

Hall said that Microsoft's main concern, and the reason it sent out Big Foot letters in the first place, was security. "If you look at what a number of sites are doing, they're asking for your Hotmail login info, They're storing your identity, which is not a best practices [approach] for anyone's data from a security standpoint. We want to make sure our data is kept between our users and our servers."

The thrust of the term sheets, he said, was to create a process whereby Hotmail and other Windows Live data could be shared securely with third parties. Added Hall: "There are models for federation where you can trust other services—and that's what we're trying to do with our partners." Thats what doesn't make sense to me. If this is such a security problem, why do Google and Yahoo let their users take their contacts with them?


Disclosure: Time Warner (TWX) is the parent company of Fortune and AOL, which competes with Microsoft via its AIM messenger service and other services.

Vinod Khosla plugs into the electric car [Green Wombat]

Wednesday, January 16th, 2008

ecomotors-engine-diagram-012008_examples.jpg

Silicon Valley green tech investor Vinod Khosla caused a stir recently when he dissed plug-in electric hybrid cars as “toys” that would not contribute much in the way of fighting global warming. The blogs were buzzing from red-faced EV enthusiasts taking umbrage at Khosla, who has made big bets on biofuels and is never shy at expressing his opinions on all matters green.

But an investment Khosla Ventures announced this week in EcoMotors, a Detroit startup developing a high-efficiency diesel engines, shows that the legendary venture capitalist is more eclectic when it comes to electrics than his public pronouncements might make him seem.

EcoMotors founders Peter Hofbrauer and John Coletti, veterans of Volkswagen and Ford (F) respectively, are engineering engines that they hope will achieve 100 miles per gallon, run on gasoline, diesel or biofuels and be used to power — wait for it — plug-in hybrid electric cars.

What drove Khosla to change his mind on hybrids? He didn’t, really. To understand why, we need to look under the hybrid hood. There are two types of hybrids. A parallel” hybrid contains two drive trains — an electric motor to power the car at low speeds for short periods of time, and a conventional gasoline engine for higher speeds. The Toyota (TM) Prius and Honda (HMC) Civic hybrid and most other hybrids on the road today are parallel hybrids. (A plug-in version would allow for a more powerful battery pack that could be recharged from a standard electrical outlet.)

In contrast, a series hybrid takes some of the complexity — and presumably the cost — out of the design by using only an electric drive train to propel the car while relying on a small internal combustion engine to power a generator that charges the battery and provides power to the electric motor when needed. The Chevrolet Volt, General Motor’s (GM) plug-in electric hybrid under development, is a series plug-in hybrid. And the EcoMotors’ engine will be designed for use in a series hybrid.

“He was referring to parallel hybrids,” says Khosla Partner’s Ford Tamer of his boss’s anti-hybrid comments made in a speech at an investor conference. “We do believe a series hybrid is the way to go. He was also referring to the fact that the hybrid platform is inherently an expensive platform.”

So is a series platform at this point, but Khosla’s vision is to drive that cost down by creating high-efficiency engines and batteries. Hence the investment in EcoMotors. And hence the hiring last September of Tamer, a former top executive at chipmaker Broadcom and a co-founder of another chip company, Agere (later acquired by Lucent). “I’ve been focused on the efficiency side of Khosla — engines, motors, turbines, even solar and batteries,” says Tamer, Khosla Ventures’ operating partner.

Khosla is the sole funder of EcoMotors – and no, Tamer won’t reveal the size of the investment – which officially launched this month and remains so stealthy it doesn’t even have a website yet.

Tamer says EcoMotors CEO Hofbrauer developed a high-efficiency engine under contract with the Defense Advanced Research Projects Agency, of DARPA, for use in military vehicles. EcoMotors has now licensed the technology for commercial use.

Here’s how it works, as explained by Tamer: the EcoMotors engine is built of 2-cylindar “modules” that can be stacked depending on the need for power – one or two modules for a car, three or four for a big truck. “If you have two modules, you can shut down one module for city driving,” says Tamer. “But when you need to need to go uphill or need power for highway driving, you engage the second module. That gives you better fuel efficiency and reduces emissions.” (EcoMotors’ renderings of the engine’s design are above.)

With the recently enacted energy bill mandating automakers raise the average fuel efficiency of their fleets to 35 miles per gallon by 2020, EcoMotors aims to demo its first engine to potential customers by early 2009.

A plug-in electric hybrid drive train will be further down the road but Khosla Ventures already has made investments in companies developing components for such a system. One such startup is Seeo, a Berkeley, Calif.-based company whose website cryptically says it is “developing advanced materials to revolutionize electricity storage and delivery.”

“Our belief is that we have to get a fuel-efficient, emissions-conscious diesel engine on its own,” Tamer says. “Then going to a hybrid becomes a bonus.”

One of Vinod Khosla’s mantras is that green technology must become cheap and scalable enough to be adopted in China and India, countries whose impact on climate change is monumental. In other words, a $25,000 plug-in hybrid doesn’t stand a chance against a Tata Nano, the Indian people’s car unveiled last week.

Remarks Tamer: “$2,500 will buy a Tata  – that’s a DVD upgrade on a Lexus.”

Solar power plant factory to open in New Mexico [Green Wombat]

Tuesday, January 15th, 2008

schott.jpegBig Solar has been about Big Dreams - fields of mirrors carpeting the desert to produce clean, greenhouse-gas free electricity. In another step toward making that vision a concrete-and-glass reality, Schott Solar announced Monday that it is building a factory in Albuquerque, N.M., to manufacture components for large-scale solar thermal power plants as well as photovoltaic modules for commercial rooftop arrays.

The German company’s news follows Silicon Valley solar startup Ausra’s announcement last month that it’s building a solar thermal factory in Nevada — the first in North America.

That solar companies are now investing capital to break ground on manufacturing plants represents the creation of a Big Solar infrastructure and, of course, a move to get on the ground floor of what is expected to be a solar building boom in the sun-drenched Southwest of the United States. Utilities throughout the region are facing mandates to dramatically increase their use of renewable energy. In California, for instance, PG&E (PCG), Southern California Edison (EIX) and San Diego Gas & Electric (SRE) are all negotiating big megawatt contracts for utility-scale solar power thermal power plants. A consortium of Southwest utilities meanwhile has put out to bid a 250-megawatt solar station.

“We certainly see the opportunity for growth in the solar thermal market,” Mark Finocchario, CEO of Shott’s North American operations, told Green Wombat. “The concentration of solar thermal plants will be in the Southwest and we see that’s where the rest of the supply market will develop as well. But we would have the ability to ship product to anywhere in the world.”

The $100 million Albuquerque factory will manufacture solar thermal receivers — long tubes that hang over curved mirrors called solar troughs. The mirrors focus the sun’s rays on the receivers and liquid inside becomes superheated to produce steam that drives electricity-generating turbines.

Finocchario says the the plant, which will employ 350 people,  is set to go online by the end of the first quarter of 2009. Future plans call for another $400 million investment to expand the factory’s workforce to 1,500.

Leaky Apple [Netly News]

Tuesday, January 15th, 2008

The Macbook Air notwithstanding, the most interesting part of this year's Macworld was that all the interesting stuff was leaked well in advance. This has rarely happened before.

Steve Jobs takes secrecy at least as seriously as he does clean design. I remember being rousted out of bed by an irate phone call from Jobs at midnight, the night before a Macworld where he was to launch the snowball iMac. I had written the cover story on that Mac for Time Magazine, and it was inadvertently published overseas on a time.com website. Ooops. We got it down, but the damage was done, and I was told later that Jobs was so upset, at one point, he wanted to call off his Macworld address.

Jobs couldn't be happy that Wired had the high points right  about the world's thinnest laptop yesterday. And I'm sure he was  displeased that details about Apple getting into the movie rental business had begun slipping out a month ago. In fact, if you read any of the top Apple fanboy sites, it was pretty clear that the Good Ship Apple was leaking all over the place.  Naturally, as is typical in such cases,  bloggers were taking great pains to claim that their predictions were based on intelligent "tea-leaf reading," as opposed to reliable tips. Given Apple's track record of shutting down unauthorized fan sites, I would, too.

A 6-Letter Word for “Hosed” [Netly News]

Friday, January 11th, 2008

Scrabulous_logo I can't tell if Hasbro (HAS), the maker of Scrabble, is the smartest company in the world or the dumbest. Over 100 million sets of the game have been sold in 121 countries, in 29 different languages, according to everyone's favorite source. What a cash cow.

So, why in the world didn't it create a free online version? And why oh why would it let someone else do it, and reap the rewards?

But that's just what happened when two guys from Calcutta, Jayant Agarwalla, 21, and his brother, Rajat, 26, created a knockoff called Scrabulous. Their site launched in 2006 and quickly signed up 600,000 registered users. Not too shabby for a year's worth of work. So the brothers launched a Facebook application in June, 2007 and the results were stunning: 2.3 million active users as of today. For those of you keeping score, the application generated 270 70 million pageviews in the past month. Not a bad deal for a two-man operation.

But all good things must come to an end, which is bad news for Scrabulous fans, and even worse for the Agarwalla Bros.: Hasbro's trying to shut the site down. "They sent a notice to Facebook about two weeks ago," Jayant confirmed to me. "The lawyers are working on it."

As a recovering Scrabulous addict (actually, I have since moved on to Facebook's harder stuff, Texas Hold 'em), I'm devastated. But as a tech writer and life-long student of what passes for Internet economics, I'm baffled. Is Hasbro just a stupid Potato Head? Or is this a brilliant game of Stratego?

My calls to the company have so far gone unanswered. A spokesman for Facebook, who said she was unaware of what was in the works with Hasbro or Scrabulous, said, "we don't typically comment on legal matters."

If I were an evil genius running a board games company whose product line spanned everything from Monopoly to Clue, I might do this: Wait until someone comes up with an excellent implementation of my games and does the hard work of coding and debugging the thing and signing up the masses. Then, once it got to scale, I'd sweep in and take it over. Let the best pirate site win! If I were compassionate, I'd even cut in the guys who did all the work for a percentage point or two to keep the site running. Perhaps that's what will happen since both the Scrabulous site and Facebook app are still up and running.

Indeed, Jayant told me that he was hopeful they'd find an 11th Hour solution. "We're trying to work out some kind of deal," he said. I hope so, too.

Jayant said that he didn't exactly understand what all the fuss was about. It's ability to generate insane numbers of pageviews notwithstanding—he said some players play as many as 170 games at a time on Facebook—the application isn;t throwing off that much money. He declined to say exactly how much, pegging revenues at "over $25,000 a month." Hmmmmm. The brothers got the idea for Scrabulous after becoming Scrabble freaks a few years ago and playing at another free site, Quadplex. After it started charging users, however, they decided to build their own "without thinking through the legal aspect at the time." Jayant pointed out that there are a number of other Scrabble knockoffs online. "I'm not sure why Hasbro actually picked on this," he added. Because, dude, you're the best.

How green is CES? [Green Wombat]

Tuesday, January 8th, 2008

2008lvcc4 The Consumer Electronics Show underway in Las Vegas is a tech Bacchanal that this year is drawing some 140,000 people to Las Vegas along with untold tons of exhibits air freighted in from around the world. In years past, CES organizers might have touted the outsized consumption that accompanies the instant creation of a mid-size city. These days that would be ecologically incorrect, of course, and CES stresses that the 20,310 tons of planet-warming carbon dioxide conference-goers will generate will be completely neutralized through the purchase of carbon offsets from the non-profit Carbonfund.org.

"CarbonFund will invest in energy efficiency, renewable energy and reforestation projects to offset the emissions created by every inch of CES space, " reads an e-mail from a CES public relations firm that landed in Green Wombat's in-box on Monday, "all show freight, the shuttle buses and 600,000 hotel rooms will be offset via investments," (In fact, CES will be the largest carbon neutral trade show EVER!)"

The cost of the CES carbon tax: $108,000. No, there's not a zero or three missing from that number. For the price of a Tesla Roadster and change, CES is cleansing the collective environmental sins of 140,000 people. Without wading into the controversial arena of carbon offsets or questioning the good intentions of CES' organizers, that number begs an obvious question: If neutralizing a looming global catastrophe comes so cheap, wouldn't have Bill and Melinda Gates just have written a check by now?

Unfortunately, when it comes to greenhouse gases, what happens in Vegas does not stay in Vegas. The very real CO2 emissions from those 140,000 people now gridlocking the Strip -- think of all those idling taxis alone -- will enter the atmosphere in real time. Worse, much of the electricity for CES is being generated by a 42-year-old coal-fired power plant north of Las Vegas that was identified in a recent report on utility emissions as the nation's worst carbon polluter.

Those emissions will in no way be immediately offset by the purchased carbon credits. The money will fund environmentally worthwhile projects but it may be years -- or decades in the case of reforestation - before they actually begin having an impact on greenhouse gas emissions. According to Carbonfund.org's website, CES' money will be invested in such things as buying renewable energy certificates from wind farms and planting trees in Nicaragua and Hungary.

CarbonFund is also letting conference-goers offset the considerable CO2 emitted by jets ferrying more than a hundred thousand people into Las Vegas. That's also a bargain: the bill for the six Fortune Magazine reporters who flew into town for CES from New York and San Francisco comes to a grand total of $23.81. At that price, you almost feel guilty about paying so little to not to feel guilty about your contribution to global warming.

CES also has taken such environmentally friendly steps as using biodegradable food utensils and recycled paper and laying down recycled carpet in an exhibit hall. But there's no getting around the fact that the confab is held in what is perhaps the United States' most unsustainable city, whose unchecked sprawl across the Mojave Desert makes it an ecological time bomb as temperatures rise and water tables fall.

Relocating the event to New York, Boston, San Francisco or another walkable, mass-transit, eco-oriented city would send a message that CES is serious about going green. Of course, it'll snow on the Strip in July before that happens. But for CES 2009, why not ditch the carbon offsets and use the money to buy a fleet of bicycles instead of clogging the streets with carbon-spewing taxis. It won't neutralize CES' greenhouse gas emissions but it would actually reduce them where it counts.

SunPower’s solar power plant building boom [Green Wombat]

Monday, January 7th, 2008

serpa2.jpg

Another day, another new solar power plant. At least that's the way it seems, given SunPower's recent spate of deals to build multi-megawatt photovoltaic solar power stations. The latest came Friday when the Silicon Valley solar panel maker announced a contract to construct an 8-megawatt solar power plant in Spain. The agreement follows a November deal for three other solar power stations in Spain totaling 21 megawatts. That in turn was preceded by an October announcement of a contract for a 18-megawatt plant in -- where else -- Spain.

See a pattern here? SunPower (SPWR) now has solar power plants totaling more than 100 megawatts built or under contract in Spain. Plus it constructed an 11-megawatt solar power station in neighboring Portugal and a 10-megawatt plant in Germany. It's sole PV power plant in the United States is a 15-megawatt station at Nellis Air Force Base outside Las Vegas.

It's no accident that SunPower has set its sights on Spain and other European markets. Spain and Portugal, for instance, offer simple so-called feed-in-tariffs that pay solar power plant operators a premium rate -- typically for 15 to 20 years -- for producing renewable energy. That makes the economics of financing and building solar power plants relatively straightforward in contrast to the patchwork of short-term state and federal green energy incentives in the U.S. (Witness the current upheaval in the industry over the crucial solar investment tax credit that expires at the end of 2008, and which Congress neglected to extend in the recently enacted energy bill.)

No wonder Europe is attracting renewable energy financiers like GE Energy Financial Services (GE), which financed SunPower's Portugal plant (pictured above). "We truly believe utility-scale solar will be an incredible opportunity,” Kevin Walsh, managing director of GE Energy Financial Services, told Green Wombat at the opening of the Portugal plant last March. (That's not to say that companies like GE don't see opportunity in the U.S. market. Just this morning, GE and SunPower announced that GE Energy Financial Services will finance and own five 1-to-2.4-megawatt commercial solar arrays in California being installed by SunPower for Toyota (TM), Hewlett-Packard (HPQ), Agilent, Lake County, and the Rancho California Water District.)

The built-in profit margin for solar in Spain and Portugal also makes photovoltaic power plants viable. PV plants are essentially residential rooftop solar arrays writ large that track the sun and convert sunlight that strikes silicon-based cells directly into electricity. But silicon is expensive and solar panels are relatively inefficient. So absent subsidies like feed-in tariffs, few PV power stations have been built in the U.S., which has focused on large-scale solar thermal power plants that use mirrors to heat water or other liquids to create steam that drives electricity-generating industrial turbines. The beauty -- literally - of a PV plant is that it contains virtually no moving parts or the bulky power blocks that contain turbines and other machinery. That means they can be built closer to urban areas and used to shoulder the load from overburdened utility substations.

Even solar panel installers are striking deals overseas. Silicon Valley-based solar installer Akeena (AKNS), for instance, developed a new solar panel system called Andalay that cuts the cost of installation for homes and businesses. The company contracted with China solar panel giant Suntech (STP) to manufacture Andalay, which will also sell the panel in Europe, Japan and Australia.
