I wrote this story for Grist, where it first appeared.

The Obama administration’s solar building boom continues. On Wednesday, Interior Secretary Ken Salazar signed the first lease to build a large-scale photovoltaic project on federal land in Nevada.

“Yes, it’s about jobs and finding a new way forward but it’s also about dealing with the crises of our time facing America,” said Salazar during a speech in Los Angeles at the Solar Power International conference, the industry’s big annual get-together. “America’s foreign policy is held hostage by the politics of oil. It is imperative that we grab this new energy future.”

It’s a significant move. The U.S. Bureau of Land Management controls a huge chunk of Nevada, prime territory for big solar power projects due to the state’s intense sunshine and a licensing process that is far less arduous than the one in neighboring California.

On stage at the conference, Salazar signed a lease for the 60-megawatt Silver State photovoltaic farm to be built by First Solar outside of Las Vegas. The secretary said it will supply enough electricity to power more than 15,000 homes.

In recent weeks, Salazar has signed off on leases for three other solar projects in Southern California that would generate 1,124 megawatts of electricity.

“We’re not done yet, we’re not done yet. Our work is just beginning,” said Salazar, who left his trademark 10-gallon hat back in Washington.

A report released Wednesday by the Solar Foundation, a non-profit research group, said that there are 93,000 people employed in the solar business in the U.S. and that a survey of employers found that they plan to add 24,000 more jobs by August 2011.

Rhone Resch, chief executive of the Solar Energy Industries Association, noted that a decade ago U.S. companies supplied 40 percent of the world’s photovoltaic products while today it’s just 10 percent.

“We hope this is a sign of a turnaround and that policymakers take note,” he said Wednesday, referring to the solar employment study.

While solar jobs exist in all 50 states, the study found that nearly 40 percent of them were created in California, the state with the most aggressive renewable energy targets.

But expect the federal government to be driving demand for solar power — for its own use.

“It’s important we all walk the talk,” Salazar said, noting that the Interior Department alone has installed more than 2,000 renewable energy projects.

In The New York Times Green blog on Wednesday, I follow up on my print story about the impact of low-cost Chinese solar manufacturers on high-tech Silicon Valley startups:

In an article in Wednesday’s paper, I write about how high-tech Silicon Valley solar companies are retooling their strategies to compete with low-cost Chinese manufacturers.

Over the last two years, Chinese solar panel makers like Suntech and Yingli Green Energy have moved aggressively into the United States and now supply about 40 percent of the California market, according to Bloomberg New Energy Finance, a research firm.

China’s growing dominance of the global solar market has been on display in Los Angeles this week at the Solar Power International conference, one of the industry’s biggest annual get-togethers. In a vast exhibition hall, the booth of one Silicon Valley start-up, Solyndra, is surrounded by a sea of Chinese solar companies offering their wares.

As prices for conventional silicon-based solar panels plummet, pressure has increased on Silicon Valley start-ups like Solyndra that make a type of photovoltaic cell called copper indium gallium selenide, or CIGS. Though less efficient at converting sunlight into electricity, the promise of the technology was that it could be made cheaply – at least until the cost of conventional solar module prices fell 40 percent over the past year.

That led Solyndra to start production two months ahead of schedule at its new $733 million factory in Fremont, Calif., and to speed up development of its next-generation solar panel.

“It definitely puts more pressure on us to bring our costs down as quickly as possible by ramping up volume,” said Ben Bierman, Solyndra’s executive vice president for operations and engineering, as driverless carts shuttled stacks of photovoltaic parts to large orange robots at Fab 1, the company’s original factory.

Nathaniel Bullard, a solar analyst with Bloomberg New Energy Finance in San Francisco, said that success for high-tech Silicon Valley solar companies may depend on finding a big market niche they can dominate.

Solyndra, for instance, makes lightweight solar panels that snap together like Legos and can be installed on large commercial rooftops unable to support heavier conventional panels. On the roof of the company’s headquarters, Mr. Bierman recently gave me an advance look at its new solar panel, which is more powerful but requires far less labor to install.

“We really took a lot of the cost out and accelerated development in response to the Chinese,” Mr. Bierman said.

China presents different challenges for SunPower, which was founded in 1985 and is the granddaddy of Silicon Valley solar companies.

SunPower makes conventional solar panels but has also pursued a high-technology strategy and says it produces the world’s most efficient photovoltaic modules. (Architects and fashion-forward homeowners also favor the company’s sleek jet-black panels.)

In recent years SunPower has increasingly focused on building big photovoltaic power plants to supply electricity to utilities that put a premium on technological performance, reliability and a company’s ability to manage complex projects.

I wrote this story for Grist, where it first appeared.

The president of the Maldives, Mohamed Nasheed (on right in above photo), didn’t just agree to have solar panels installed on the presidential mansion; he helped put them in. Nasheed scrambled up to the roof this week, screwdriver in hand, and joined the crew from California’s Sungevity, which installed the 11.5-kilowatt photovoltaic array.

(Don’t expect to see Barack Obama in a hard hat any time soon, even though his administration just gave the OK to the solarization of the White House.)

The Maldives, of course, is the poster country for global warming. The Indian Ocean archipelago rests, on average, fewer than five feet above sea level and the nation of some 305,000 people would be rendered uninhabitable by rising waters.

“For the Maldives, climate change is a real challenge,” said Nasheed on a conference call Wednesday. “It’s not a problem in the future, it’s a problem we face every day.”

“We have 16 islands that have serious erosion problems,” he added. “We’ve had to relocate people from one island to another. We also have severe saltwater contamination. We have a serious food security issue.”

Sungevity and Bill McKibben’s 350.org were behind the campaign to put solar on the U.S. White House. The Maldives rooftop installation is part of this Sunday’s 10/10/10 “Global Work Party,” another McKibben initiative to get people to take action against climate change.

Nasheed, 43, has shown himself adept at focusing media attention on the impact of global warming on the world’s low-lying island nations — last October, he and his cabinet donned scuba gear to hold an underwater meeting.

But putting solar panels on the presidential home is not so much a PR stunt as part of the nation’s aggressive efforts to wean itself from the imported oil it relies on to generate electricity.

In January, Nasheed pledged to the United Nations that the Maldives would go carbon neutral by 2020. Making good on his pledge won’t turn back the rising tide, but Nasheed said the Maldives can show other island nations that it is possible to replace fossil fuels with renewable energy. “If it can work here in the Maldives it can work anywhere with 300,000 people,” he said. “We’re going to see a very big technology shift. There’s going to be another industrial revolution. If you’re not clever enough to embrace the future, you cannot be a world leader.”

According to an official in the president’s office, the Maldives total electricity demand is 200 megawatts.

A Finnish company, WinWind, has proposed building a 25-megawatt wind farm on the Maldives’ Gaaf Alif atoll, while Indian wind turbine maker Suzlon is investigating the feasibility of constructing a 15-megawatt wind farm on the Addu atoll. Japan has provided financial assistance for a project to install a megawatt’s worth of rooftop arrays on schools and government buildings in Male, the country’s capital.

International donors, meanwhile, have promised $30 million for renewable projects. Scotland and the Maldives have signed an agreement to investigate the potential for developing wave and tidal power in the archipelago, according to the president’s office.

To provide electricity when there’s no wind or sun, the Maldives is considering biomass power plants that would run on coconut husks. Outlying islands, however, would probably have to continue burning oil until the price of batteries used to store renewable energy became affordable.

LG, the Korean company, donated the panels for the presidential solar array and the inverters were contributed by the German company Kaco. Sungevity used satellite images and its proprietary software to size and design the solar system at its Oakland, Calif., headquarters, then flew a crew to the Maldives to install it.

“We’re averting about 200 tons of C02 from the system and there’s a 27 percent return on investment,” said Danny Kennedy, Sungevity’s co-founder and a former Greenpeace activist, who traveled to the Maldives for the installation. “President Nasheed is demonstrating this is a wise and affordable investment.”

Or as Nasheed put it, “For us, it is an issue of life or death. We have been living in the middle of the Indian Ocean and have a written history that goes back 1,000 years. We cannot relocate.”

“We have to take direct action,” he continued. “As the president, it’s difficult for me to talk like this. This has to involve a fair amount of direct action on the streets.”

In The New York Times on Friday, I write about a report showing venture capital investment in green technology companies nose-dived in the third quarter of 2010, with California taking a big hit:

Has the green tech recovery stalled?

Global venture capital investment in green technology companies fell 30 percent, to $1.53 billion, in the third quarter of 2010, according to a preliminary report issued Friday by the Cleantech Group, a San Francisco-based research and consulting firm.

The amount invested in North America, Europe, China, India and Israel in the third quarter is also 11 percent below the year-ago quarter, when investment tanked amid the recession.

The numbers are striking, given that investment in green-tech startups soared in the first half of this year, surpassing records set in 2008 at the height of the clean technology boom.

“Much like we see globally, I think businesses and investors are grappling a little bit with a recovery that hasn’t yet taken off, and I think people are trying to figure out how quickly will the growth occur,” Sheeraz Haji, president of the Cleantech Group, said during a conference call Friday. “I think we’re seeing a little bit of the same in clean tech.”

California, an epicenter of green technology innovation, suffered a precipitous decline, with investment falling 61 percent.

Mr. Haji questioned whether uncertainty over the fate of California’s global warming law, known as A.B. 32, played a role in the falloff in investment. A measure on the November ballot, Proposition 23, would suspend A.B. 32 until the state unemployment rate falls to 5.5 percent for four consecutive quarters.

“We can’t help but wonder that uncertainty around Prop 23 has impacted that,” he said, cautioning that it is difficult to draw hard conclusions based on one quarter’s data. “

The global warming law requires California to cut its greenhouse gas emissions to 1990 levels by 2020. Mr. Haji noted that venture investment soared after the law’s enactment in 2006 as investors poured money into solar startups and companies developing energy efficiency services and electric cars.

Even so, investors put $452 million into California companies in the third quarter, versus $126 million for second-place Texas.

While the rest of North America experienced a rise in investment in the third quarter, California’s poor performance led to a 42 percent decline for the region as a whole.

Not so with Asia. For instance, investment in China jumped to $153 million in the third quarter from $30 million in the second quarter of 2010.

I wrote this story for Grist, where it first appeared.

While efforts to pass federal climate change legislation have stalled and a fight rages in California to overturn its global warming law at the ballot box, Golden State regulators have been licensing massive desert solar power plant projects at a breakneck pace in recent weeks.

On Wednesday, for instance, the California Energy Commissioned approved two solar projects that would generate nearly 1,000 megawatts of electricity, the 250-megawatt Genesis Solar Energy Project and the 709-megawatt Imperial Valley Solar Project.

Since Aug. 25, the energy commission has licensed six solar thermal power plants that would cover some 39 square miles of desert land and generate 2,829 megawatts. That’s nearly six times as much solar capacity that was installed in the United States last year, mostly from rooftop solar panels.

“Consider how important it is that California move aggressively toward renewables and how important these pioneering projects are,” said Jeffrey Byron, a member of the California Energy Commission, said at a hearing Wednesday.

Regulators and developers are racing to put shovels to ground before the end of the year when federal incentives for large renewable energy projects expire, which could threaten the financial viability of some of the solar projects.

The Genesis project, to be built by Florida-based energy giant NextEra Energy Resources (formerly called FPL), will build long rows of parabolic troughs in the Riverside County desert that will focus sun on liquid-filled tubes suspended over the mirrors to create steam that will drive an electricity-generating turbine. It’s an older solar technology that was first deployed in the 1980s in California.

Tessera Solar’s  Imperial Valley project, on the other hand, will be the first big test of Stirling dish technology. Resembling a giant mirrored satellite receiver, the 38-foot-high, 40-foot-wide, solar dish focuses the sun’s rays on a Stirling engine, heating hydrogen gas to drive pistons that generate 25-kilowatts of electricity. Some 29,000 of Tessera’s Suncatchers will be installed on more 6,400 acres of desert land near the Mexican border about 100 miles east of San Diego.

Meanwhile, California Gov. Arnold Schwarzenegger this week signed into law what is thought to be the nation’s first energy storage legislation. The bill, AB 2514 could result in regulations requiring the state’s utilities to store a certain percentage of electricity generated in energy storage systems such as batteries, compressed air or flywheels.

Energy storage is considered crucial for the mass deployment of solar power plants, wind farms and other sources of intermittent renewable energy, as well to build out the smart grid.

I wrote this story for Grist, where it first appeared.

General Electric on Wednesday gave a jump-start to Better Place, the Silicon Valley startup developing an electric car infrastructure in several countries.

Better Place plans to deploy a network of urban charging posts and swapping stations where drivers can exchange depleted company-owned batteries for fresh ones when they need to make trips that exceed their car’s range. GE has agreed to help finance up to 10,000 of those batteries in Better Place’s first two markets: Denmark and Israel. That’s no small matter, given that Better Place faces huge capital outlays for battery purchases.

The global conglomerate will also make its WattStation, a sleek electric car charging post that it unveiled in July in San Francisco, compatible with Better Place’s network.

In addition, GE and Better Place will collaborate on an effort to persuade companies to electrify their vehicle fleets and plug into the electric car charging networks that Better Place plans to build in the San Francisco Bay Area; Ontario, Canada; Australia; and Europe.

It’s not the first time GE has dabbled in the nascent electric car industry. In 2008, the company invested $4 million in Think, the Norwegian electric carmaker.

In yet another deal involving a multinational conglomerate and a California startup, Sharp late Tuesday said it had acquired Recurrent Energy, a San Francisco-based solar developer, for $305 million in cash.

While most people may associate Sharp with televisions and other consumer electronics, the Japanese company is also one of the world’s biggest solar panel makers. Recurrent builds small-scale photovoltaic power plants. It has signed contracts for projects that would generate 330 megawatts, and has another nearly another 1,700 megawatts’ worth of deals in development.

During a conference call on Wednesday, Recurrent’s chief executive, Arno Harris, said Recurrent would retain its name and become a division of Sharp and that he and his team would remain in place.

While the buyout is another sign of the consolidating solar industry, it also indicates that big solar panel makers like Sharp feel pressure from the fast rise of low-cost Chinese manufacturers to diversify their business.

Acquiring Recurrent gives Sharp another source of revenue but it won’t necessarily provide a market for Sharp’s own solar panels. In a telling provision of the acquisition, Harris said Recurrent won’t be compelled to buy Sharp solar panels and can keep its current suppliers. Those include Yingli Green Energy, a Chinese company that captured a third of the California market last year thanks in large part to a big deal with Recurrent.

I wrote this story for Grist, where it first appeared.

When Walmart announced on Monday that it would install 15 megawatts’ worth of solar arrays on as many as 30 of its stores in California and Arizona, it set out to shape the solar market in more ways than one.

The reason? The world’s biggest retailer specified that many of the new solar installations should use thin-film photovoltaic panels. Thin-film solar cells are printed or deposited on glass or flexible materials. And although they are less efficient at converting sunlight into electricity, they can be produced at a lower cost than traditional crystalline silicon solar cells.

Thin-film solar currently accounts for just about 20 percent of the solar market. The most technologically advanced versions have had a difficult time grabbing market share due to competition with low-cost Chinese crystalline silicon manufacturers and a recession that has dried up investor funding.

Enter Walmart.

“By leveraging our global scale to become a more efficient company, we are able to lower our expenses and help develop markets for new technologies,” Kim Saylors Laster, Walmart’s vice president of energy, said in a statement. “Developing and incorporating new renewable energy sources, like thin film, reduces energy price risk and aligns very well with our commitment to solving business challenges through technology.”

Walmart signed a deal with SolarCity, a leading Silicon Valley solar installer, to manage the project. SolarCity will install and own the photovoltaic arrays on Walmart stores and sell the electricity to the retailer.

SolarCity’s chief executive, Lyndon Rive, told me Monday that the company will install thin-film solar arrays made by First Solar and Miasolé.

First Solar, which makes an older variant of the technology called cadmium telluride, is the world’s biggest thin-film manufacturer and Walton family members were early investors in the Tempe, Ariz., company. First Solar is also an investor in SolarCity, which already uses its photovoltaic panels.

Miasolé, a Silicon Valley startup, is one of a number of companies that has developed a type of thin-film solar cell called copper indium gallium selenide, or CIGS, that offers the promise of higher efficiencies and lower costs.

“Walmart wanted to see thin-film be adopted and made that a requirement in the bidding process,” says Rive.

He noted that the retailer did not dictate the percentage of stores that should receive thin-film solar arrays but expects the technology will account for the majority of installations over the next year.

“There’s no hard and fast number but they’d like us to do as much as possible,” said Rive.

Another twist in the Walmart deal is that the company collaborated with the Environmental Defense Fund (EDF) to develop the criteria used to select SolarCity. (EDF, which maintains an office near Walmart’s headquarters in Bentonville, Ark., has long worked with the retailer on sustainability initiatives.)

The goal, Walmart said in a statement, “was to identify the most innovative solar technologies that would create benefits on three fronts — to the environment, technology, and financial viability.”

The bigger ambition, though, is to shape the solar market, as Walmart acknowledged.

“The company’s large scale on-site installation of CIGS could help further the development of this technology and bring it to market quicker, while use of cadmium telluride thin film could help make the case for other businesses to adopt the technology for on-site commercial use.”
