In a follow up to my story in Friday’s New York Times on the beginning of a solar building boom in the desert Southwest, I take a look at California regulators’ approval of the seventh Big Solar farm in two months, the 663.5-megawatt Calico project:

In an article in Friday’s paper, I write about the solar thermal power plant building boom now under way in California’s Mojave Desert. The looming expiration of crucial federal financial support for the multibillion-dollar projects, though, could turn the boom to bust.

But that hasn’t deterred California regulators, who on Thursday approved the seventh large-scale solar thermal farm since late August.

After years of painstaking environmental review, the California Energy Commission has been green-lighting the massive solar power plants at warp speed so developers can break ground before year’s end and qualify for a government cash grant that covers 30 percent of the cost of construction.

The latest approval goes to Tessera Solar’s Calico project, to be built in the San Bernardino County desert in Southern California. Originally proposed to generate 850 megawatts -– at peak output, that’s close to the production of a nuclear power plant -– the project was whittled down to 663.5 megawatts to lessen the impact on wildlife like the desert tortoise and the bighorn sheep.

It’s difficult to appreciate the sheer scale of even the smaller version of the Calico project until you’ve seen Tessera’s Suncatcher solar dishes on the ground. A few years ago I had the opportunity to visit a prototype six-dish Suncatcher solar farm at the Sandia National Laboratories in New Mexico.

Resembling a giant mirrored satellite receiver, each Suncatcher stands 40 feet tall and 38 feet wide with a Stirling engine suspended on an arm over the center of the dish. As the dish tracks the sun, its mirrors concentrate sunlight on the hydrogen gas-filled heat engine. As the superheated gas expands, it drives pistons, which generates 25 kilowatts of electricity.

Now imagine planting 26,540 Suncatchers on 4,613 acres of federal land for the Calico project. Tessera, based in Houston, has also received approval for a 709-megawatt solar power plant to be built in California near the Mexico border. That will require the installation of 28,360 Suncatchers.

“These desert solar projects will provide clean power for our schools, homes, and businesses while reducing fossil fuel consumption, creating local jobs, and reducing the greenhouse gas emissions that threaten California’s economy and environment,” Anthony Eggert, a member of the California Energy Commission, said in a statement on Thursday.

The cost to build the two projects will exceed $4.6 billion, according to Tessera, and it’s highly unlikely that they’ll go online unless the company receives federal loan guarantees that allow developers to borrow up to 80 percent of construction costs on favorable terms. That program expires next September, and Tessera needs to start putting steel into the ground by the end of the year to qualify for the cash grant program.

In Friday’s New York Times, I write about the beginning of the long-awaited solar boom in the Mojave Desert and how it may well be short-lived if crucial federal incentives for renewable energy are allowed to expire in the coming months:

NIPTON, Calif. — The long-promised solar building boom in the desert Southwest is finally under way. Here in the Mojave Desert, a dice throw away from the Nevada border, giant road graders and a small army of laborers began turning the dirt for BrightSource Energy’s $2 billion Ivanpah project, the first large-scale solar thermal power plant to be built in the United States in two decades.

The Ivanpah plant is the first of nine multibillion-dollar solar farms in California and Arizona that are expected to begin construction before the end of the year as developers race to qualify for tens of billions of dollars in federal grants and loan guarantees that are about to expire. The new plants will generate nearly 4,000 megawatts of electricity if built — enough to power three million homes.

But this first wave may very well be the last for a long time, according to industry executives. Without continued government incentives that vastly reduce the risks to investors, solar companies planning another dozen or so plants say they may not be able to raise enough capital to proceed.

“I think we’re going to see a burst of projects over the next two months and then you’re going to hear the sounds of silence for quite a while,” said David Crane, chief executive of NRG Energy, on Wednesday after he announced that his company would invest $300 million in the Ivanpah plant.

Solar developers depend on two federal programs to make their projects financially viable. The most crucial is a loan guarantee program, expiring next September, that allows them to borrow money on favorable terms to finance up to 80 percent of construction costs.

The other is the option to take a 30 percent tax credit in the form of a cash payment once a project is built. Although the tax credit does not expire until the end of 2016, the option to take it as a cash payment disappears this year, making it far less valuable to a start-up company that is just beginning to generate revenue.

With both Democrats and Republicans promising to rein in the federal budget, it is unclear whether lawmakers will extend the programs in any form. “That could stall a number of projects and even lead to the failure of some,” said Ted Sullivan, an analyst with Lux Research, a consulting firm in New York.

Yet no one in the desert here wants to think too much about those looming clouds.

“Ivanpah represents a transformational moment in our energy equation,” said John Woolard, BrightSource’s chief executive, who was joined Wednesday by Gov. Arnold Schwarzenegger of California and Interior Secretary Ken Salazar at Ivanpah’s groundbreaking ceremony. “It demonstrates that the U.S. can lead in the drive for renewable energy at scale by building the largest solar plant in the world with new technology.”

The eight California projects that are expected to break ground this year will turn 46 square miles of the desert into a futuristic landscape of mirrors, towers and solar dishes. State officials estimate the plants will create 8,000 jobs in a state with a 12.4 percent unemployment rate.

During its three years of construction, Ivanpah will employ as many as 1,000 laborers in a recession-scarred region.

“In the last year, I haven’t worked,” said Basilio Yniguez, a 36-year-old pipefitter and father of seven, as he helped build a holding pen last week for threatened desert tortoises on the Ivanpah site. “Thanks to the green thing going up, I’m working.”

The state is supporting the industry in part by mandating that California utilities get a third of their electricity from renewable sources by 2020.

“When you look at the raw number of kilowatt-hours we need, I don’t see how you get there without large central station solar projects,” said Pedro Pizarro, a top executive with Southern California Edison, one of the state’s largest utilities.

Unlike the photovoltaic panel systems found on rooftops, most of the new solar plants will use thousands of large mirrors to heat liquids to generate steam that drives conventional electricity-generating turbines.

“Without the Department of Energy coming in to assume a lot of the risk, you might not find lenders willing to lend, particularly if you’re a start-up with untried technology,” said Nathaniel Bullard, a solar analyst at Bloomberg New Energy Finance.

Other hurdles also stand in the way of the solar expansion. For some plants, multibillion-dollar transmission lines must be built to carry electricity from the desert to cities. Some environmentalists continue to oppose the projects’ impact on imperiled wildlife, such as the desert tortoise, and may sue to stop construction.

The competitiveness of large-scale solar thermal plants in California also depends on the cost of natural gas, the state’s dominant source of electricity. According to Mr. Bullard, gas-fueled plants can produce electricity for about 10 cents a kilowatt-hour. After including the government subsidies, solar thermal plants are expected to generate power at 13 to 17 cents a kilowatt-hour, which the industry says is close enough in price to be competitive.

So far, Ivanpah is the only California solar thermal project to win a government loan guarantee, although other projects have applied and are awaiting decisions from the Energy Department.

“We are sensitive to the deadlines and are doing everything we can so that these projects can move forward,” said Jonathan Silver, the executive director of the department’s loan program. “There’s a significant demand for these funds.”

The uncertainty has left even some of the licensed solar projects in limbo.

In Yale Environment 360 on Wednesday, I interview John Woolard, chief executive of BrightSource Energy, the California solar developer that has begun construction of the first large-scale solar thermal power plant to be built in the United States in two decades:

Today, California Gov. Arnold Schwarzenegger, Interior Secretary Ken Salazar, and other dignitaries gathered in the Mojave Desert to officially break ground on BrightSource Energy’s Ivanpah Solar Electric Generating System, the first large-scale solar thermal power plant to be built in the United States in nearly two decades.

BrightSource is one of a half-dozen big solar farms, with a combined electricity-generating capacity of 2,829 megawatts, licensed by the California Energy Commission over the past two months. By year’s end, California and federal regulators expect to approve additional projects that will produce a total of 4,143 megawatts. At peak output, that’s the equivalent of several nuclear power plants and more than seven times the solar capacity installed in the United States last year.

The approval of the projects comes after years of environmental review and controversies over the installations’ impact on water, wildlife, and fragile desert landscapes. The power plants licensed so far will cover some 39 square miles of desert land with a variety of new and old solar thermal technologies. Unlike rooftop photovoltaic panels that directly convert sunlight into electricity, solar thermal uses the sun to heat liquids to create steam that drives electricity-generating industrial turbines.

BrightSource’s 370-megawatt Ivanpah project, located just over the California border, 40 miles southwest of Las Vegas, is the world’s largest solar-thermal power plant project currently under construction. The company, led by CEO John Woolard, received a $1.37 billion loan guarantee from the United States Department of Energy to build the project, which will deploy 347,000 large mirrors that will surround three towers on 3,500 acres of federal land. The mirrors will focus the sun on a water-filled boiler that sits atop the tower to create high-temperature, high-pressure steam.

Woolard, 45, came to BrightSource as chief executive in 2004 after co-founding Silicon Energy, an energy efficiency software company, and stints at California utility PG&E, the Lawrence Berkeley National Laboratory, and VantagePoint Venture Partners, a leading Silicon Valley green tech venture capital firm. He sat down with Yale Environment 360 contributor Todd Woody at BrightSource’s Oakland, Calif., headquarters to talk about the future of Big Solar and the challenges the industry faces — from a woefully inadequate electricity grid to the imperative of minimizing water use — as multibillion-dollar projects finally begin to become a reality.

Yale Environment 360: Are we witnessing the birth of a major new solar industry in the United States?

John Woolard: I hope. The number I always go back to is that we have done 74,000 permits for oil and gas in the last 20 years and we finally have five or six for solar. That’s a good step forward. The agencies are learning how to permit, they’re learning how to move forward. It’s great for the industry and we can finally get some size and consequence.

e360: As the photovoltaic industry increasingly becomes dominated by overseas companies in China and elsewhere, does the sheer scale of these solar thermal projects in the U.S. give the country the opportunity to become the technological and market leader?

Woolard: Oh, yeah. Solar thermal is very different from [photovoltaic technology]. The power has different characteristics and is more reliable. They’re almost apples and oranges. Solar thermal has got very interesting We don’t have a quantity and energy problem; It’s a collection and distribution problem.” attributes and characteristics that make it unique.

In the U.S. we’re lucky. The southwestern U.S. has high desert, which means it’s closer to the sun, less atmosphere to go through. It’s the best solar resource anywhere, outside the Anaconda Desert in Chile or a few places. Harnessing that resource effectively is the most important thing. So we don’t have a quantity and energy problem; it’s a collection and distribution problem.

e360: BrightSource’s Ivanpah project is not only the first large-scale solar thermal project to break ground, it is the first to deploy a new power tower technology. Why is that significant?

Woolard: Our team was part of building older trough plants and you learn a lot. If you take a power tower, you get higher temperatures and pressures. That gives you higher thermo-to-electrical conversion efficiency. Think of that as more efficiency, less waste, lower cost. Because of that, you need fewer mirrors, less solar field, and you have a more efficient design.

The other gets down to how you actually build on the land. If you take the older trough designs or anything with a lot of mirrors, [it] would degrade the land. It’s more damaging from a soil and runoff perspective.

The big [problem] is water. What is the world going to look like over the next 20, 30, 40 years? Water in the desert is going to become a much more challenging proposition. So we’ve gotten water usage down to a minimum — the lowest of anybody in the world, basically.

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

The United States is on the verge of a solar boom that could provide 4.3 percent of the nation’s electricity by 2020, according to a new report from Bloomberg New Energy Finance.

There’s just a 12-figure catch: Investors need to put $100 billion into the solar industry to keep the generation of solar electricity growing by 42 percent a year for the next decade to expand capacity from the current 1.4 gigawatts to 44 gigawatts.

“Policy measures such as tax credits, capital expenditure grants, generation incentives and renewable electricity credits will remain a key driver of solar uptake in the U.S. for at least the next three years,” according to the report from Bloomberg New Energy Finance, a research and consulting firm. “The current drop in solar costs is taking place just as such policies are being implemented by the federal and various state governments, which is expected to lead to rapid growth in commercial, utility and residential solar power.”

Over the past two years, solar module prices have plunged by 50 percent as low-cost Chinese manufacturers expanded production and entered the U.S. market.

“Policy, rather than sunshine, will remain the U.S.’s greatest solar resource for the next few years,” Milo Sjardin, Bloomberg New Energy Finance’s head of U.S. research, said in a statement. “By the middle of this decade, however, the U.S. retail solar market will be driven by fundamental, unsubsidized competition, which should transform the U.S. into one of the world’s most dynamic solar markets.”

Exhibit A for such a phenomenon is Germany. With about as much sunshine as Maine, the European nation became the world’s solar stronghold through policies that rewarded homeowners, businesses, and farmers for generating their own electricity.

Such policies are needed in the U.S., according to the report, given that solar electricity remains four times as expensive to generate than coal-fired power.

Of course, the failure of Congress to pass national climate change legislation and the current attempt to kill California’s global warming law shows that progress on green energy issues is not guaranteed in the U.S. And Congress’ habit of offering short-lived tax incentives for renewable energy and then dithering about extending them when they expire has played havoc with the industry and investors.

Bloomberg New Energy Finance predicts photovoltaic panels will account for 30 gigawatts of the 44 gigawatts of solar electricity generation by 2020, with 14 gigawatts coming from solar thermal power plants. Solar thermal farms deploy huge arrays of mirrors to heat liquids to create steam that drives electricity-generating turbines.

That might be a conservative estimate, if the California and federal officials’ rush to green light big solar projects in recent weeks is any indication. On Monday, for instance, Interior Secretary Ken Salazar approved a 1,000-megawatt solar thermal power plant to be built in the Southern California desert.

By year’s end, nearly four gigawatts of solar thermal projects are expected to be licensed. Just 10 gigawatts to go until 2020.

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.
