Utility chief: we want to fuel the auto industry

Posted in environment, green cars, green tech, PG&E, renewable energy, Think, Think Global, Uncategorized, tagged , , , , , on April 22, 2008| 2 Comments »

PASADENA, Calif. — If you wanted a snapshot of the emerging alliance between utilities and automakers, the car park of the Langham hotel here was the place to be Tuesday morning. There was the CEO of one of the largest utilities in the United States putting the pedal to the metal of the battery-powered Think City with Think Global CEO Jan-Olaf Willums riding shotgun.

“I liked it a lot,” PG&E (PCG) Chairman and CEO Peter Darbee told Green Wombat after a few spins around the hotel in the electric coupe. “The acceleration was fast, it handled well and it has a European feel.”

We had just finished a Fortune Brainstorm Green session on electric cars (along General Motors’ (GM) executive Beth Lowery), where Darbee declared, “We want to replace the oil industry” as the fuel supplier to the automakers. Fuel in this case is electricity, though unlike Big Oil, regulated utilities such as PG&E and Southern California Edison (EIX) will not make windfall profits no matter how many electrons they push into Chevy Volts.

The topic at hand was the potential for vehicle-to-grid, or V2G, if electric cars go mass market. The big idea: electric cars are essentially mobile generators and rolling energy storage devices. When hundreds of thousands of them are plugged in, they can not only download electricity but return power to the grid from their batteries, allowing utilities to meet peak demand without firing up expensive fossil fuel power plants that often sit idle until everyone cranks up their air conditioners.

PG&E is working with Google (GOOG) to develop technology to allow a smart power grid to detect where an electric car is plugged in so the owner can be charged or credited with consuming electricity or returning it to the grid. The smart grid would also be able to detect power demand spikes and then tap the appropriate number of car batteries to smooth out the electricity supply.

Utilities like PG&E are eager to forge alliances with electric carmakers for other reasons. In California, electric cars could be charged at night when greenhouse gas-free power sources like wind farms tend to produce the most electricity but when demand otherwise falls off. Utilities are also interested in buying used electric car batteries (which retain 80 percent of their capacity even after they’re no longer good for transportation) to store renewable energy that can be released when electricity demand spikes.

Lowery, GM’s vice president for environment, energy and safety policy, said such interest from utilities is prompting the automaker to think how electric cars could spawn new markets. “We’re definitely looking at different business models for batteries,” she said.

On Monday, Think Global and venture capital powerhouses Kleiner Perkins Caufield & Byers and Rockport Capital Partners announced the formation of Think North America as a joint venture between the Norwegian company and the VCs that will bring the Think City to California next year.

Rockport managing general partner and acting Think North America president Wilber James was at the panel and suggested Think supply some cars to PG&E. As the session ended, Darbee, James and Willums headed to the parking lot where Willums showed off the car’s Internet-enabled interactive features, including a video screen with a button already labeled “vehicle-to-grid.”

GMOs, blind faith in nukes and Second Life

Posted in biofuels, environment, green tech, nuclear energy, tagged , , , , , on April 22, 2008| 2 Comments »

Fortune senior editor David Kirkpatrick reports from Fortune’s Brainstorm Green conference:

PASADENA, Calif — One of the more interesting observations I’ve heard at Fortune’s Brainstorm Green conference concerned genetically-modified foods and nuclear power. Someone commented that these two things — historically the object of huge vituperation from environmentally-minded critics — are both seeing a modulation of criticism.

The world is undergoing a food crisis caused, at least in part, by an undue emphasis on biofuels and in any case closely connected to the dramatically increased price of oil. (I certainly hope the issue of biofuels and food comes up when Adam Lashinsky interviews biofuel’s crown prince Vinod Khosla.) In the face of this food crisis, the antipathy toward GMOs may be starting to fade. The recent moves by Korea to allow in American beef after long resisting it, and by Japan to allow American rice, may just be early signs, this guy said. I’d speculate also that if it’s a question of starvation or survival, the southern African nations which have so adamantly opposed GMOs will almost certainly rethink their positions. (Aside from Zimbabwe’s Mugabe, of course, from whom rationality cannot be presumed.)

In a session on the topic of nuclear power, Fortune’s David Whitford asked the audience how many were unalterably opposed to increasing nuclear power in the U.S. for any reason. In this room of perhaps 300 environmentally-minded Americans, only about 20 raised their hands. With oil at $116 and global warming an ever-more urgent concern, minds are opening. Not that most of those in the room wouldn’t add substantial caveats to their unwillingness to rule nuclear out.

That said, the advocacy of nuclear power shown by Alex Flint of the Nuclear Energy Institute on Whitford’s panel drifted to some absurd extremes. For instance, he said that he would be willing to have a nuclear waste facility in his backyard, and that the location of a nuclear power plant “as close as possible” to his house “would be good for land values.” What is this guy smoking?

In answer to my question — one also raised by his co-panelist David Lockbaum of the Union of Concerned Scientists — about what happens if a jet piloted by a terrorist plows into a nuclear plant, Flint was unconvincing. He claims that studies show that plants’ containment vessels are strong enough to prevent any release of radiation. To which Lockbaum replied that all the studies pre-9/11 found that even if that were the case, the shaking that would be inevitable in such a scenario would sever essentially all pipes and cables in and out of a plant, making a meltdown likely. Studies since 9/11 are classified, he noted, adding “but the laws of physics did not change that day.”

In the random interesting comments category, I was struck by an amazing statistic proffered by IBM’s (IBM) Rich Lechner in a session on Greening the IT industry. There were plenty of convincing arguments being made in the room that IT and the intelligence bequeathed by computing can have a major impact on reducing energy use and carbon releases.

But Lechner noted that a virtual person in Second Life has a larger carbon footprint than the average person in Brazil. His point, presumably, was that as people enter a developed economy, their carbon footprint goes way up along with their increasing use of tech.

The Green Consumer: Myth or reality?

Posted in consumers, corporate green, environment, green marketing, green packaging, green tech, the green economy, tagged , , on April 22, 2008| 26 Comments »

Fortune associate editor Julie Schlosser reports from Fortune’s Brainstorm Green conference:

PASADENA, Calif — Consumers are feeling the pressure to go green. And it’s hard to ignore. Drinking bottled water is a definite no no. Flying across the country? Buy offsets. The consumer is being bombarded with green marketing and advertising and the result might not be what you expected. All this green guilt and messaging just might be making consumers more skeptical about the growing assortment of green products.

When polled, most consumers overwhelmingly say they want to buy green, according to Joel Makower, head of Greener World Media and author of The Green Consumer. But they aren’t actually doing it. According to the research, Makower says, “If it is green, consumers assume it isn’t good.” And that means, in many cases, green products are entering the marketplace with a deficit.

That was part of the discussion at Monday afternoon’s panel, “The Green Consumer: Myth or reality?” Andrew Shapiro, founder and CEO of GreenOrder, a strategic consulting firm that works with big brands such as GE (GE), GM (GM), Starwood (HOT) and Office Depot (ODP), moderated the panel that included Stonyfield Farm founder Gary Hirschberg, Elizabeth Lowery of GM, and Makower.

Hirschberg, the CE-Yo (yes, you read that correctly) of Stonyfield Farm, the world’s largest organic yogurt company, has a fun story to tell. He took organic yogurt into the mainstream long before organics were cool, and he has built a $300 million-per-year business along the way. He has also managed to incorporate green principles throughout the product’s life cycle. “But we don’t even use the word green when we describe what we do,” he pointed out.

Still, he argues, there is obviously a green consumer. “But we think they are more focused on quality.” And the quality does something that millions of dollars in advertising can’t. It creates loyalty, says Hirschberg. “And if loyalty comes from an emotional place, authenticity is the key to creating it.”

What consumers are showing us is that if your company has a high “talk-to-do ratio” when it comes to going or being green, you’ll lose the consumer’s trust immediately. By adopting a sense of humility and focusing on communicating honestly with your consumers, Hirschberg argues, companies can build loyalty.

So how does a company build such a relationship with their customer? By offering them a premium product and one that isn’t just greener, but tastes better, lasts longer, or is more aesthetically pleasing. And as the economy continues to slow, the best way to get a consumer to go green is to give them the goods for less.

Tough road for new carbon emissions laws

Posted in climate change, environment, global warming, green policy on April 22, 2008| 1 Comment »

Fortune editor-at-large David Whitford reports this week from Fortune’s Brainstorm Green conference:

PASADENA, Calif — Climate-change legislation is coming, that’s the first point to emerge Monday from two panels at Fortune’s Brainstorm: Green conference — one that looked at politics and policy, the other at the costs, risks and opportunities that await us all in a carbon-constrained America. But new regulations may not be coming as fast as we think, that was one surprise. And by itself, legislation won’t be enough.

None of the experts who spoke could imagine a bill of any kind being signed into law within the next year at the earliest. Most stretched the timetable to as far as 2011. There are lots of reasons for that, but here’s what it comes down to, says California Attorney General (and former governor) Jerry Brown: “The threat [of global warming] is more obscure to the average person, and the costs [of legislation] are very real.” That clash, he says, “will make significant climate change legislation rather difficult.”

A lot revolves around coal. It doesn’t matter how some House Democrats may feel about the need for prompt action to stave off global warming. As long as they represent coal districts (as 27 of them do), they’ll have a hard time passing a law that hurts their constituents’ pocketbooks. The challenge lies in devising legislation that’s tough enough to do the job, says Fortune’s Marc Gunther, but not so tough that it has no chance of ever being approved.

Fred Krupp, who leads the Environmental Defense Fund, was hopeful nonetheless. He sees an “enormous upwelling of pressure” within the business community that will make a cap-and-trade system for reducing carbon emissions a reality in the next 18-24 months. “America has to get on with this,” he said, and not just in the policy arena.

Want to be the next Bill Gates or Warren Buffett? Krupp asked. Enormous rewards await those who can devise ways to suck carbon out of smokestacks, or even out of the air. “If we use the profit motive,” Krupp said, “and only if we use the profit motive, we will solve this.”

Kleiner Perkins, Think Global launch U.S. electric car company

Posted in electric cars, environment, green cars, Think Global, tagged , , , , , on April 21, 2008| 26 Comments »

PASADENA, Calif. — Norwegian electric carmaker Think Global is bringing its zippy urban runabout to the United States.

On Monday at Fortune’s Brainstorm Green conference, Think launched its North American operation with Silicon Valley venture capitalist heavyweight Kleiner Perkins Caufield & Byers and Boston’s Rockport Capital Partners as lead investors.

Think North America will sell the Think City, its two-seater battery-powered car, as well as a forthcoming five-seater called the Think Ox.

“We thought this would be a wonderful vehicle to bring to the U.S.,” said Kleiner partner Ray Lane. He’ll serve as chairman of Think North America, which will be a 50-50 joint venture between Think and Kleiner/Rockport. They declined to put a price tag on the investment but Lane said “we’ll invest what it takes.”

The Think City began rolling off the production line in Norway earlier this year and Think already has announced it will sell the car in France, the U.K. and Scandinavia. With its current battery, the City can go about 110 miles on a charge at a top speed of around 62 miles an hour. Lane said Think North America aims to sell the car in the U.S. market for less than a Toyota (TM) Prius, which retails for around $25,000. Batteries being developed by Think’s partners A123Systems in collaboration with General Electric (GE) will boost the range and top speed, Willums has noted.

“This is not just a one-off kind of deal,” says Rockport’s Wilber James, who is serving as Think North America’s president while a CEO search is underway. “Being venture capitalists, we’re on the cutting edge in battery technology. We’re not just passive investors; we’re very active in this company.”

Think CEO Jan Olaf-Willums, who appeared on stage with Lane and James, said he hopes to sell a few thousand cars next year — starting in California — and then ramp up to 30,000 cars. “We can put assembly plants anywhere in six months,” said Willums, referring to Think’s $10 million modular factories.

James and Lane seemed taken with the little electric. “I had the privilege of sitting in back of the City while Ray Lane drove the car with Jan-Olaf through the streets of Geneva,” said James. “It’s a fun car to drive.”

Green Wombat can confirm that. I drove a Think City last year when I visited Willums in Norway for a story I wrote for Business 2.0 magazine. The stylish two-seater with the roof-to-bumper glass hatch accelerates like a sports cars, thanks to the instant transmission of power from the electric motor to the wheels.

Willums brought two Thinks – one a sporty orange convertible, the other a black coupe — to Pasadena. “That will be a big seller in Los Angeles,” Lane told Green Wombat as a crowd gathered around the cabriolet in the Southern California sunshine outside the Langham hotel in Pasadena.

Since I drove the City last, it’s been been upgraded with an interactive, Internet-enabled touchscreen. The City will sync with your home computer, download your schedule, your shopping list and monitor your battery usage and driving habits, according to Dipender Saluja, whose Silicon Valley startup, Automatik, is developed the the technology to create what Willums calls a “computer on wheels.” The onboard system is designed to communicate with a smart utility grid so that the owner can be charged or credited for the electricity consumed or returned back to the grid from the car’s battery.

On Monday, I got behind the wheel of the Think City that sported a large sunroof and took a quick spin around the hotel grounds with Willums. Version 2.0 of the car was a more refined iteration of the pre-production car I drove last year in Norway but still a blast to drive.

Lane and Willums said Think will begin by selling a few thousand cars to corporate fleets. He also said Think North America is in discussions with utilities like PG&E (PCG).

eSolar scores $130 million from Google, other investors

Posted in environment, Google, green tech, renewable energy, solar energy, solar power plants, Uncategorized, tagged , , , , on April 21, 2008| 7 Comments »

PASADENA, Calif. — Solar power plant builder eSolar has raised $130 million from Google’s philanthropic arm, Google.org, and other investors.

That was the headline news that eSolar chairman and Idealab founder Bill Gross slipped to Green Wombat during dinner Sunday night as Fortune’s Brainstorm Green conference kicked off in Pasadena. The other investors include Idealab and Oak Investment Partners. Big numbers grab attention but the far more interesting angle is the technology that eSolar is developing. If it lives up to its claims, eSolar could help break the logjam that has put Big Solar on the slow track in California.

“We just completed tests at our test site this week and we will be able to produce electricity that is competitive with coal,” said an animated Gross Sunday evening.

That is the Holy Grail of renewable energy and the charge set out by Google (GOOG) founders Sergey Brin and Larry Page when they launched their green power initiative, RE<C (Renewable Energy less than Coal), in November. Google.org subsequently invested $10 million in Pasadena-based eSolar. (eSolar did not say how much of the $130 million Google.org ponied up in the latest round.)

eSolar has been operating in stealth mode but Gross shared details of the company’s technology and how it intends to produce greenhouse gas-free electricity so cheaply — a claim sure to be met with some skepticism by competitors like Ausra, BrightSource Energy and Solel.

At first glance, there doesn’t seem much radically different about an eSolar solar thermal power plant — it’ll use fields of mirrors to focus the sun’s rays on a tower containing a water-filled boiler. The resulting heat will create steam that will drive an electricity-generating turbine.

The tipping-point innovation, according to Gross, is the mirrors and the software that controls them as well as the modular design of the power plants.

While Oakland, Calif.-based BrightSource is developing a similar system, Gross says eSolar is able to use smaller mirrors — called heliostats — that can be cheaply mass produced from off-the-shelf glass like that used in bathroom mirrors. Proprietary software developed by eSolar controls each sun-tracking mirror, increasing their efficiency to produce more electricity. “It’s all about the software,” Gross said.

Smaller more powerful solar fields means that eSolar can build power plants on far less land than competitors for less money, according to Gross. For instance, a 500-megawatt solar power plant can cost more than $1 billion to build and requires thousands of acres of land — which is why most will built in remote deserts. But eSolar plans to build modular, 33-megawatt power plants that can be constructed on a couple hundred acres and plugged into existing transmission lines near urban areas.

“We’ve already bought up rights to enough land to produce more than a gigawatt of electricity,” said Gross, showing Green Wombat a map of California polk-a-dotted with the locations of potential eSolar power plants. A gigawatt can power about 750,000 homes.

The small size of each power plant has another benefit — solar thermal power stations under 50 megawatts do not have to be licensed by the California Energy Commission. That means eSolar can cut at least a year or two off the process of getting a solar power plant online.

That will certainly be attractive to the Golden State’s big utilities — PG&E (PCG), Southern California Edison (EIX) and San Diego Gas & Electric (SRE) — which face a mandate to obtain 20 percent of their electricity from renewable sources by 2010 and 33 percent by 2020.

Although all those utilities have signed massive megawatt deals with solar energy companies, no plant has been yet built.

Gross says that while eSolar has been talking to the utilities it’s not going to wait to have a power purchase agreement in hand before building its first plant.

“Sergey said to go for it and we are.”

The Dell of solar energy

Posted in environment, green tech, renewable energy, solar energy on April 18, 2008| 11 Comments »

For longtime Australian Greenpeace activist Danny Kennedy, one of the environmental group’s more memorable moves was when the Sydney crew climbed the roof of the prime minister’s home and installed solar panels to protest the government’s preference for Big Coal over renewable energy. (Note: Do not try this on the White House.)

These days, there’s a new, greener PM in power and Kennedy is in California, running a solar startup that aims to minimize the time spent on rooftops by doing for the solar business what Dell did for personal computers: Digitizing the entire enterprise to cut costs and create a mass market.

Putting photovoltaic panels on residential rooftops remains largely a labor-­intensive cottage business, often involving multiple visits to a client’s home to make the sales pitch, measure the roof, and design a custom system. Sungevity, which officially launches Tuesday on Earth Day, takes all that online.

Enter your address on its website, and satellite-imaging software zooms in on your home, and Sungevity’s proprietary algorithm calculates the roof’s dimensions — the pitch and azimuth — selects appropriately sized solar arrays, and shows what they will look like installed — while computing your return on investment. Once the order is placed, one of five off-the-­shelf prepackaged solar arrays is shipped to the customer’s door, and an installation crew is dispatched. A database tracks local building and permit requirements, sending the necessary forms to the homeowner for their signature while beaming local regulations governing solar arrays to the installation crew.

“This changes the game,” says Kennedy, 37, who co-founded Sungevity last year after leaving Greenpeace and relocating from Sydney to Berkeley. (Full disclosure: Kennedy’s kids and Green Wombat’s son attend the same elementary school.)

Kennedy and his partners have raised $2.7 million from investors that include German solar giant Solon and actress Cate Blanchett. “Our technology allows us to size up an entire city remotely and work out what the solar potential of the roof space is,” adds Kennedy, who will be speaking at Fortune’s Brainstorm Green conference on Monday. “This is the real secret sauce, the thing that rocks the house.”

Says Joe Kastner, an executive with solar financier MMA (MMA) Renewable Ventures: “If you do a lot of site visits, that can end up being a big portion of the cost. Anything that can make these projects more efficient and cut the costs on the front end is good.” He adds that Sungevity may appeal to potential customers accustomed to managing their lives online and who are loathe to hang out at home waiting for solar sales or service people to show up. “I would be interested in doing as much as possible over the Internet,” Kastner says. “There’s definitely a market for it.”

Rather than employ its own installers, Sungevity will work with unions to train electricians and other contractors so that it can tap pools of green-­collar workers in local markets. “That’s probably long-term what’s most needed to achieve a million solar roofs,” says Kennedy, referring to California’s solar target. “[Solar panel] supply is not the big constraint. The real issue is labor — it’s the limiting factor in the growth of the industry.”

At the company’s Berkeley offices down the street from Chez Panisse, Kennedy and Andrew Birch, a board member and solar economics expert, run through a live demo of the Sungevity system. In about 15 minutes, a spokesmodel had walked a potential customer through the sales pitch and ordering process while on the backend a consultant is sizing up the roof with the software tools. Within a day or so an e-mail will be sent to the customer with different solar array options and the relative return on investment. “With a traditional solar installer, that would have been about a two week process,” says Kennedy.

Whether this all works so smoothly once volumes of real-life orders start coming over the transom remains to be seen, of course. And the limits of the system become apparent when Birch types in my Berkeley address and the picture shows a large Japanese maple overhanging my house, which would have ruled out a solar array except the tree had been removed a year and a half earlier. Kennedy acknowledges that leafy cities like Berkeley with its mishmash of architectural styles and every-which-way rooflines are problematic. Instead, Sungevity’s target market is middle-American suburbia, with its vast tracts of cookie-­cutter houses.

That’s just fine with potential rival SolarCity, the Foster City, Calif., solar installer backed by PayPal co-founder and Tesla Motors chairman Elon Musk. “Their technology works very well for track homes — that’s maybe 2% of our business,” says SolarCity CEO Lyndon Rive. “Our market is more retrofit homes, existing homes in well-established areas that are looking to go solar.”

“I like it when companies like Sungevity get into the market,” he adds. “They’re forcing innovation and the most important thing is the widespread adoption of solar.”

Sungevity’s launch comes as utilities like Southern California Edison (EIX) and PG&E (PCG) and tech giants like Google (GOOG) are pushing for a mass expansion of solar energy.

Nat Kreamer, president of San Francisco-based solar installer Sun Run, says Sungevity’s move to digitize the solar business is valuable but it will have to focus on the installation process to really get costs down. “Once you figure out how to size up someone’s system, the challenge is the speed you can get it built,” he says.

Installation costs account for roughly half of a solar system’s cost and solar installers like Akeena Solar have developed modular arrays containing wiring and other components to minimize the time spent on installation.

Sungevity will not focus on zeroing out customers’ electricity bills, but like Sun Run, will push the “hybrid home” – selling smaller, cheaper solar systems that will cover that portion of a home’s electricity use that is the most expensive to buy from a utility.

For instance, after rebates, a standardized Sungevity solar array for a four-bedroom home in Northern California will cost about $21,000 and deliver an estimated return on investment of 13% over the system’s 25-year life.

“We’re selling this as an economic asset,” says Kennedy, “not just as a way to go green.”

Too late for Big Solar to save the day?

Posted in BrightSource Energy, climate change, corporate green, enviro capitalism, environment, global warming, solar energy, solar power plants on April 1, 2008| 14 Comments »

brightsource_energy.jpgCalifornia utility PG&E on Tuesday announced contracts to buy up to 900 megawatts of electricity generated by solar power plants to be built in the Mojave Desert by BrightSource Energy. It’s one of the biggest solar deals to date — enough to power some 600,000 homes — and is another sign that that the shift from fossil fuels to carbon-free energy is well underway, at least in California.

But is it too late? PG&E (PCG) first announced it was negotiating a power purchase agreement with BrightSource, then called Luz II, on Aug. 10, 2006. Around that time, the United States’ leading climate scientist, NASA’s James Hansen, warned that the world had only a decade to take drastic action to cut carbon emissions and avert future catastrophe from global warming.

It took nearly two years alone to just hammer out the PG&E-BrightSource deal and the world now has eight years left to radically ramp up alternative energy sources. By the time the first BrightSource 100-megawatt solar power plant (image above) goes online it will be 2011 and the last one will begin generating electricity for PG&E just as the climate change alarm clock goes off. If you believe Hansen, hitting the snooze button will not be an option.

Of course, there’s no guarantee the BrightSource plants will actually be built — it will take billions to construct them and the investment climate is not exactly sunny these days, clouded by Wall Street’s meltdown and the looming expiration of a crucial solar investment tax credit. (Personally, Green Wombat is betting BrightSource pulls it off — though April Fool’s Day probably was not the best date to unveil such a deal. The Oakland, Calif.-based company was founded by solar pioneer Arnold Goldman, its CEO, John Woolard, hails from Silicon Valley and the startup is backed by Morgan Stanley (MS) and some savvy venture capitalists. )

Given the moral and regulatory imperative — California utilities must obtain 20 percent of their electricity from renewable sources by 2010 and a third by 2020 — why is large-scale solar proceeding at the pace of a Mojave Desert tortoise? (Almost three years ago, for instance, Southern California Edison (EIX) and San Diego Gas & Electric (SRE) unveiled agreements with Phoenix’s Stiring Energy Systems to buy up to 1,750 megawatts of solar electricity. Ground has yet to be broken on any of the planned power plants.)

Partly it’s because the years-long negotiations between utilities and solar power plant companies is something of a black box. Details of these power purchase agreements are kept confidential but are estimated to be worth billions — if a recent $4 billion dealstruck by utility Arizona Public Service with solar power plant builder Abengoa Solar is any indication. Regulated utilities are by their nature big and bureaucratic and can be expected to be extra-cautious when they’re placing bets on untried solar technology from companies like BrightSource and Ausra.

“Transactions of this magnitude require a fair amount of time to negotiate and due diligence must also be performed,” PG&E spokeswoman Jennifer Zerwer told Green Wombat in an e-mail. “The original [BrightSource agreement] announced in August 2006 was for 500 megawatts; the final agreement expanded on the original . . . and culminated in the execution of five separate power purchase agreements for up to 900 MW.”

Another factor is a regulatory structure that is an artifact of the fossil fuel age. California requires extensive environmental review of new power plant projects — be they clean and green or down and dirty — a process that can take a 18 months or more. And the best solar sites often are on federal land in the Mojave — securing a lease for that land is another 18-month-long process.

Still, one looks to history. When the United States entered World War II, it retooled its factories in a matter of months to produce planes and tanks. Climate change is an amorphous but no less dangerous threat and speeding up the regulatory timetable will be crucial in the fight against global warming.

The clock, after all, is ticking.

California utility to turn roofs into solar power plants

Posted in energy, enviro capitalism, environment, global warming, PG&E, solar energy, Southern California Edison on March 27, 2008| 42 Comments »

img_2698.jpg

Southern California Edison plans to install 250 megawatts’ worth of solar panels on commercial rooftops, generating enough electricity to power 162,000 homes.

It’s a potentially game-changing move, one that could lower the cost of solar cells as manufacturers ramp up production to meet the utility’s schedule of installing a megawatt-a-week of arrays until it reaches the 250-megawatt target. That alone is more than United States’ entire production of solar cells in 2006 and will generate as much electricity as a small coal-fired power plant, albeit with no greenhouse gas emissions. “This project will turn two square miles of unused commercial rooftops into advanced solar generating stations,” said John Bryson, CEO of the utility’s parent company, Edison International (EIX), in a statement Wednesday night.

The $875 million initiative also marks the first big foray into so-called distributed energy by a major utility. Instead of building a centralized power station and the expensive transmission system needed to transmit electricity to the power grid, Edison will connect clusters of solar arrays into existing neighborhood circuits. A significant hurdle for the massive megawatt solar power plants planned for California’s Mojave Desert is the need in some cases to build multi billion-dollar transmission systems through environmentally sensitive lands to bring the electricity to coastal metropolises.

Solar arrays of course only generate electricity when the sun is shining, but they produce the most power during the hottest part of the day when Southern Californians crank up their air conditioners. The arrays could help spare Edison from having to fire up a fossil-fuel power plant when demand peaks.

Edison spokesman Gil Alexander told Green Wombat that the utility expects the project’s scale to allow arrays to be placed on roofs at half the cost of a typical installation. Edison’s ambitions could prove a boon for solar cell makers like SunPower (SPWR) and Suntech (STP) as well as solar installation companies such as Akeena (AKNS). One unknown is whether the demand created by Edison will drive up costs in the short term, given ongoing shortages of polysilicon, the base material of solar cells. The Edison project could also help jump-start the market for thin-film solar panels, which typically use far less silicon than conventional solar cells.

Alexander says Edison is already negotiating with solar panel makers and installers. Needless to say, the project will up local hiring of green collar workers.

Here’s how the solar roofs initiative will work: Edison will lease 65 million square feet of warehouse rooftop space from building owners. (The target area is the fast-growing “Inland Empire” of Riverside and San Bernardino counties.) The utility will contract for the installation of the arrays and will retain ownership of the solar systems. California regulators appear inclined to approve the project, which will be financed by a hike in utility rates.

“This will be a utility-scale solar power plant, if one thinks of the 100 or so buildings on which the two square miles of solar panels will be installed,” Alexander wrote in an e-mail. “One advantage of this project is that we will tap unused rooftop real estate directly in areas we serve where demand is growing rather than securing a major plat of land in a remote area and then building transmission lines to bring the power to those areas of rising demand.”

Anyone who has driven through Los Angeles can attest to the endless acres of big-box stores, warehouses and strip malls and thus the potential to generate green power from sun-baked suburban sprawl.

Edison’s solar roof ramp up is likely to put pressure on California’s other big utilities, PG&E (PCG) and San Diego Gas & Electric (SRE), to follow suit. Like Edison, they face a state mandate to obtain 20 percent of their electricity from renewable sources by 2010 and 33 percent by 2020. California’s global warming law requires the state’s greenhouse gas emissions to be rolled back to 1990 levels by 2020.

The Governator himself gave a not-so-subtle nudge to Edison’s competitors. “These are the kinds of big ideas we need to meet California’s long-term energy and climate change goals,” said Gov. Arnold Schwarzenegger in a statement. “I urge others to follow in their footsteps. If commercial buildings statewide partnered with utilities to put this solar technology on their rooftops, it would set off a huge wave of renewable energy growth.”

Abu Dhabi’s solar venture

Abu Dhabi is not content to just sell you the oil that fuels your SUV; now its going to sell you sunshine to keep your lights on and power your electric car when the internal combustion engine goes the way of the buggy whip. Masdar, the oil-rich emirate’s $15 billion renewable energy venture, and Spanish technology company Sener on Wednesday announced a joint venture called Torresol Energy to build large-scale solar power plants in Australia, Europe, the Middle East, North Africa and the United States.

Torresol initially will invest $1.2 billion in three solar power plants to be built in Spain but the company is targeting the global “sunbelt” for future expansion. Masdar will take a 60 percent ownership stake in Torresol with Sener holding a 40 percent stake. A Torresol spokesman declined to reveal the dollar amount of the investment. A prime market for Torresol will be the U.S. desert Southwest, where companies like Ausra, BrightSource Energy, Solel and Abengoa Solar are competing for contracts with utilities PG&E (PCG), Arizona Public Service (PNW) and Southern California Edison (EIX). Torresol potentially could shake up that market, given its very deep pockets and ability to independently finance billion-dollar solar power plants.

The venture is just the latest move by Abu Dhabi to control what Masdar CEO Sultan Ahmed Al Jaber described to Green Wombat recently as “the whole value chain” of renewable energy, from research and development to manufacturing silicon for solar cells to the large-scale deployment of green technology.

The irony is too rich to leave unsaid: A leading oil producer invests billions in carbon-free energy while a leading consumer of fossil fuels – the United States – continues to subsidize Big Oil while while offering only tepid support for green technology. It is inevitable that climate change will foster the rise of renewable energy – the only question is which countries and companies will profit from the new energy economics. It is entirely possible that the U.S. will trade energy dependence of one kind – on Middle East oil – for another – on Middle East and European solar technology – in the era of global warming. It’s no coincidence that most of the solar energy companies with contracts to build utility-scale power plants in California and the Southwest have overseas roots – Ausra hails from Australia, BrightSource was founded by American-Israeli pioneer Arnold Goldman, Solel is based in Israel and Abengoa is headquartered in Spain.

Torresol plans to build solar power plants using a technology it calls a Central Tower Receiver system. It’s similar to technology used by competitors like BrightSource in that fields of mirrors called heliostats focus the sun’s rays on tower that contains a receiver. In this case the receiver is filled with salt which when heated vaporizes water to create steam that drives an electricity-generating turbine. The company says it intends to have 500 megawatts of solar electricity online by 2012.
