In today’s New York Times’ Green Inc. blog, I write about a literally green pool cleaner that could upend a $3 billion industry:

As its license plates proclaim, Minnesota is the Land of 10,000 Lakes.

Now a Minneapolis-area company says it has figured out the secret to the state’s famously crystalline watering holes: moss.

Specifically, species of sphagnum moss that the startup, Creative Water Solutions, envisions will keep tens of thousands of swimming pools clean while drastically reducing the use of chlorine and other harsh chemicals.

The patented treatment system, which the company has sold for backyard swimming pools since 2007, underwent its first large-scale commercial test this summer at a public aquatic complex in St. Paul.

“I think this is going to have a dramatic effect and change the whole aquatic industry,” said Thomas Schaffer, a 35-year pool industry veteran hired by the City of St. Paul to monitor the moss treatment of an Olympic-size pool and a smaller children’s pool. “We saw a one-third decline in chlorine demand for the water immediately. We’re now using two-thirds less chlorine.”

The U.S. Department of Energy on Friday began accepting applications for at least $3 billion in direct funding of renewable energy power plant projects.

The funding, part of the federal stimulus package, is in lieu of a 30 percent investment tax credit that green energy developers can take on their projects. Given that most solar and wind developers carry no tax liabilities, they have relied on investment banks and other investors to front the hundreds of millions and billions of dollars in financing needed for their projects in exchange for the tax credits. But as the economy tanked along with investment banks, demand for so-called tax equity partnerships evaporated.  Big Solar projects stalled and wind developers delayed turbine orders.

Curiously, the Department of Energy said on Friday that the $3 billion would fund some 5,000 projects. That works out to about $600,000 per power plant. But a single 250-megawatt solar power plant alone can cost more than a $1 billion and would thus soak up $300 million or 10% of the funding pool.

The question is, will DOE end up funding a few large-scale green energy projects that could start to give, say, the solar thermal industry economies of scale, or will it spend the money on hundreds of smaller renewable energy facilities?

That’s a crucial issue for solar developers like Tessera Solar/Stirling Energy Systems, eSolar and BrightSource Energy, which is backed Google (GOOG), Morgan Stanley (MS) and VantagePoint Venture Partners as well as a clutch of oil giants – Chevron (CVX), BP (BP) and Norway’s StatoilHydro.

Also left unsaid in the DOE’s announcement was the fact that renewable energy projects need to break ground by the end of 2010 to qualify for the direct funding. Which is why BrightSource, Nextera Energy (a subsidiary of utility giant FPL Group (FPL) ) and Tessera Solar are eager to expedite the lengthy California licensing process and get their projects approved before New Year’s Eve 2010 so they can put shovel to dirt and start shoveling cash into their coffers.

Stirling Energy Systems Solar One project

Green Wombat spent several months looking into allegations that California labor unions are using environmental laws to pressure  solar developers to hire union workers to build large-scale solar power plants. The story was published last Friday in The New York Times:

SACRAMENTO — When a company called Ausra filed plans for a big solar power plant in California, it was deluged with demands from a union group that it study the effect on creatures like the short-nosed kangaroo rat and the ferruginous hawk.

By contrast, when a competitor, BrightSource Energy, filed plans for an even bigger solar plant that would affect the imperiled desert tortoise, the same union group, California Unions for Reliable Energy, raised no complaint. Instead, it urged regulators to approve the project as quickly as possible.

One big difference between the projects? Ausra had rejected demands that it use only union workers to build its solar farm, while BrightSource pledged to hire labor-friendly contractors.

As California moves to license dozens of huge solar power plants to meet the state’s renewable energy goals, some developers contend they are being pressured to sign agreements pledging to use union labor. If they refuse, they say, they can count on the union group to demand costly environmental studies and deliver hostile testimony at public hearings.

If they commit at the outset to use union labor, they say, the environmental objections never materialize.

Pew clean energy report

Clean energy jobs grew 9.1% over the past decade and now number 770,000 as the green tech economy makes inroads in every U.S. state and outstrips conventional job creation, according to a new study released Wednesday by The Pew Charitable Trusts.

Non-green energy jobs, in contrast, grew by 3.7% between 1998 and 2007. The traditional fossil fuel industry employed 1.27 million workers in 2007.

Pew worked with California research firm Collaborative Economics to conduct an actual count of 68,200 businesses engaged in its definition of the clean energy economy — activity that “generates jobs, businesses and investments while expanding clean energy production, increasing energy efficiency, reducing greenhouse gas emissions, waste and pollution, and conserving water and other natural resources.”

Clean energy economy jobs were divided into five sectors: clean energy, energy efficiency, environmentally friendly production, conservation and pollution mitigation, and training and support.

“Americans are struggling to get a sense of the nation’s economic future,” Lori Grange, interim deputy director of the Pew Center on the States, said on a conference call Wednesday morning.  “The nation’s clean energy economy is poised for explosive growth.”

“It just isn’t California,” she added. “Every state has a piece of the clean energy economy.”

Nevertheless, California remains a clean-energy unto itself and boasted 125,390 jobs generated by 10,209 green businesses in 2007. The Golden State, not surprisingly, attracted $6.6 billion in venture capital funding between 2006 and 2008, six times the amount captured by the runner-up, Massachusetts. Startups focused on clean energy and energy efficiency scored 80% of venture capital investments. California also led in clean energy patents, with 1,401 granted between 1998 and 2007 compared to New York’s 909.

California, however, is getting a run for its money from Oregon, Colorado and other states. Oregon had one of the fastest rates of clean energy job creation and those jobs accounted for the highest percentage of overall employment compared to other states — between .82% and 1.02%.

And Texas, for instance, is the world’s sixth-largest producer of wind energy, Pew researchers said.

The report’s patent numbers offer one indication of where the clean energy economy is headed. Between 1999 and 2008, batteries accounted for 46.6% of the patents while fuel cells took 25.6%. Solar had 8.7% of all clean energy patents and wind had 5%.  However, the growth rate in battery patents fell 33% between 1999 and 2008 while fuel cell patents jumped 96% and hybrid system patents grew 147%. Solar patents fell 15% as wind patents grew 155%.

The average annual salaries for clean energy jobs ranged from $21,000 to $111,000, according to the Pew report.

State policies requiring renewable energy production and energy efficiency measures have played a significant role in driving green energy job growth, the Pew authors said. A map showing regions with the biggest green job growth correlate with a map of states with the strongest renewable energy policies.

California utility PG&E has signed a deal for the world’s first space-based solar power plant, to be built by a secretive Southern California startup staffed by veterans of the U.S. Air Force, Boeing and Lockheed Martin.

In papers filed Friday with the California Public Utilities Commission, San Francisco-based PG&E asked for approval of a 15-year, 200-megawatt contract with Solaren, a Manhattan Beach, Calif.-based company that plans to put satellites in geosynchronous orbit by 2016 to collect solar energy. The sunlight would then be transmitted to a ground station in Fresno, Calif., in the form of radio frequency waves and converted into electricity to be distributed into the power grid. Since the sun shines 24/7 in space, a Solaren solar farm could theoretically supply “baseload” green electricity to coal-dependent regions without access to abundant sources of renewable energy.

While PG&E won’t spend any money until Solaren beams down electricity, it’s uncertain whether regulators will be willing to count a contract for such unproven, bleeding-edge technology toward the utility’s state-mandated obligation to obtain 20% of its power from renewable sources by 2010 and 33% by 2020. After all, the utilities commission last year rejected PG&E’s contract with a wave energy firm on the grounds that the technology was too early stage. PG&E’s discussion of the Solaren project’s viability was filed under a request for confidentiality.

“Solaren is using an innovative space-based solar technology, which, if successful, would represent a break-through in the renewable power industry,” Brian Cherry, PG&E’s vice present of regulatory relations, wrote in the utility’s 24-page application. “While emerging technologies like space solar face considerable hurdles under a traditional viability analysis, PG&E believes that potential, significant benefits to its customers from a successful space solar installation outweigh the challenges associated with a new and unproven technology.”

Space-based solar has long been a dream and numerous studies have been conducted on its potential viability. In the documents filed with the utilities commission, PG&E (PCG) asserted that the biggest technological obstacle is building satellites that can collect megawatts’ worth of sunlight rather than transmitting the energy miles to a ground station.

“The engineering challenge of building a Space Solar Power Plant is not the energy conversion process itself, but the need to engineer and build MW-class SSP satellites, which are much larger than current kW-class communications satellites,” Cherry wrote. “Solaren’s patented SSP Plant design employs the SSP concept described above to deliver renewable electricity to PG&E.”

Solaren’s website offers a single page that contains no information on the company other than the slogan, “Energy for Tomorrow with Technology of Today.”

In its filing, PG&E said that, “Solaren was founded in 2001 to develop, engineer, test, construct, and operate space solar generating stations. Solaren has informed PG&E that its team is comprised of experienced satellite engineers and space scientists with 20 to 45 years of experience in the leading edge space industry and come from various aerospace organizations that include the U.S. Air Force, Hughes Aircraft Company, Boeing (BA), and Lockheed Martin (LMT).

Not all the hurdles to space-based solar are likely to be technological. While there are no desert tortoises in space or other protected wildlife that live on earth-bound sites for big solar power plants, any orbiting solar farm will have to pass muster with a long list of state, federal and international government agencies. Among them, the U.S. Department of Defense, NASA and the United Nations, according to PG&E.

As the Nevada legislature debates extending tax breaks for large-scale solar power plants, a new report finds that ramping up solar development in the Silver State could produce thousands of good-paying green jobs while generating nearly $11 billion in economic benefits.

The study from San Francisco-based non-profit Vote Solar concludes that 2,000 megawatts’ worth of big solar thermal and photovoltaic farms — needed to meet Nevada’s electricity demand — would result in 5,900 construction jobs a year during the plants’ building phase, 1,200 permanent jobs and half a billion dollars in tax revenues.

“It is likely that such an investment in solar generating facilities could bring solar and related manufacturing to Nevada,” the reports authors wrote. “The economic impact of such manufacturing development is not included in this analysis, but would add significant additional benefits.”

Vote Solar’s job projections are based on an economic model developed by the National Renewable Energy Laboratory to project the impact of solar trough power plants, the most common, if dated, type of Big Solar technology.

The different solar technologies set to come online in the next couple of years could change that equation. No doubt thousands of jobs will be generated by Big Solar but just how many will depend on the mix of solar thermal and photovoltaic power plants that ultimately come online. New technologies like BrightSource Energy’s “power tower,” Ausra’s compact linear fresnel reflector and Stirling Energy Systems’s solar dish may generate similar numbers of jobs. But then there’s eSolar’s power tower solar farms – which uses fields of mirrors called heliostats to focus the sun on a water-filled boiler, creating steam that drives an electricity-generating turbine.  eSolar’s small and prefabricated heliostat arrays cut out much of the skilled labor typically needed on such projects as they can be installed by two workers using a wrench.

Photovoltaic farms essentially take rooftop solar panels and put them on the ground and thus don’t require highly skilled laborers to build turbine power blocks, miles of piping and other infrastructure needed in solar thermal facilities. (They also can be built much more quickly than a solar thermal plant, which is why utilities have been striking deals with companies like First Solar (FSLR) and SunPower (SPWRA) for PV farms.)

A second report released this week — from the Large-Scale Solar Association, an industry group — found that Nevada could gain an edge over Arizona and California in luring solar power plant builders if it extended and sweetened tax incentives.  The three states form something of a golden triangle of solar, offering the nation’s most intense sunshine and vast tracts of government-owned desert land that are being opened up for solar development.

The timing of the reports was no accident. The Nevada Legislature held hearings earlier this week on extending tax breaks for Big Solar that expire in June, and Vote Solar’s utility-scale solar policy director, Jim Baak, went to Carson City to lobby legislators, hoping to head off one proposal to tax renewable energy production.

The Large-Scale Solar report, prepared by a Las Vegas economic consulting firm, found that if legislators let the tax breaks sunset, as it were, the developer of a 100-megawatt solar power plant would pay $55.1 million in taxes in Nevada during the first 15 years of the facility’s operation compared to $26.1 million in Arizona and between $36.1 and $37.9 million in California. If the current incentives are kept, tax payments drop to $25.1 million. A bigger tax break would reduce the tax burden to $14.3 million.

Can Google help defuse a simmering green civil war between renewable energy advocates and wildlife conservationists in the American West?

That’s the idea behind a new Google Earth mapping project launched Wednesday by the Natural Resources Defense Council and the National Audubon Society. Path to Green Energy will identify areas in 13 western states potentially suitable for massive megawatt solar power plants, wind farms, transmission lines and other green energy projects. The app will also pinpoint critical habitat for protected wildlife such as the desert tortoise in California and Wyoming’s sage grouse as well as other environmentally sensitive lands.

“This was information that was unavailable or very scattered,” said Google.org program director David Bercovich at a press conference. “The potential cost savings from this will be enormous. If we can get people to the right areas and streamline the process that will have enormous benefits in getting clean energy online faster.”

NRDC senior attorney Johanna Wald said her group already is using Path to Green Energy in New Mexico to help plan a new transmission project. “Careful siting is the key to renewable energy development,” she said, noting that NRDC has mapped 860 million acres. “We’re not greenlighting development on places that are on our map but we’re providing a framework for discussion.”

siting2The unveiling of Path to Green Energy comes two weeks after California Senator Dianne Feinstein announced she would introduce legislation to put as many as 600,000 acres of the Mojave Desert off limits to renewable energy development to protect endangered wildlife and their habitats.  Solar developers have filed lease claims on a million acres of federal land in the California Mojave and there are state and federal efforts already under way to identify green energy zones across the West.

Path to Green Energy is designed to give regulators and developers a tool to choose the best potential sites for solar and wind farms so they don’t get bogged down in years-long and multimillion-dollar fights over wildlife.  Ausra, BrightSource Energy and other developers of the first half-dozen solar power plant projects moving through the licensing process in California have spent big sums on hiring wildlife consultants who spend thousands of hours surveying sites for desert tortoises, blunt-nosed leopard lizards and other protected species.

The Google Earth app won’t do away with the need to do such detailed environmental review but puts in one package a variety of information that developers must now cobble together themselves — if they can find it. Path to Green Energy could also prove valuable to utilities like PG&E (PCG) and Southern California Edison (EIX) as more and more projects are proposed and regulators scrutinize the cumulative impact of Big Solar power plants across regions.

For instance, in California’s San Luis Obispo County, three large-scale solar farms are being planned within a few miles of each other by Ausra, SunPower (SPWRA) and First Solar (FSLR). That has resulted in delays as wildlife officials initiate studies looking at how all those projects affect the movement of wildlife throughout the area. Going forward, Path to Green Energy will give developers a snapshot of where the wild things are, as well as wildlife corridors to help them avoid siting one plant too close to another in a way that may impede animals’ migration. That could save millions of dollars in mitigation costs – money builders must spend to acquire land to replace wildlife habitat taken for a power plant project as well as avoid fights with environmental groups that have become increasingly uneasy about Big Solar projects.

If the desert tortoise is the critter to avoid when building solar power plants in the Mojave, the sage grouse poses problems for Wyoming wind farms. Brian Rutledge, executive director of Audubon Wyoming, said Path to Green Energy shows the densities of sage grouse across the state, allowing developers to stay clear of those areas.

“We get a solid indication of where energy development shouldn’t go,” he said. “Just as important, we get a better sense of the places that should be evaluated for wind turbine farms and transmission lines. The maps make clear that there is plenty of room for green energy.”

The payback from using Web 2.0 software could indeed be tremendous, given that Google (GOOG) spent a scant $50,000 in donations to NRDC and Audubon to create the maps.

Along with the rest of the economy, venture capital investment in green technology has fallen off the proverbial cliff, according to a survey released Wednesday by market research firm the Cleantech Group.

Global investment in renewable energy, electric cars and other green tech dropped 48% to $1 billion in the first quarter of 2009 from the previous year and fell 41% from the previous quarter. (Global here being defined as North America, Europe, China and India.)

The survey, conducted with Deloitte, found that the size of the average round of funding also crashed, from $20 million in the fourth quarter of 2008 to $12.3 million in the first quarter.

Solar captured the biggest chunk of VC cash at $346 million, with the money going to companies like concentrated photovoltaic startup SolFocus and Norwegian polysilicon maker Norsun.

“Venture funds continue to invest significant sums, albeit at a slower pace and smaller scale than in the past two years,” Brian Fan, the Cleantech Group’s senior director of research, said in a statement.

North America remains the epicenter of green tech investing, with nearly two-third of all of investments in the first quarter.

IBM on Tuesday said it has signed  a deal to help build a smart grid for utility EnergyAustralia. Some 12,000 sensors will be installed on the Australian utility’s transmission network around Sydney to monitor electricity distribution and detect outages and other problems. It’s IBM’s largest smart grid project of its type to date.

Big Blue will build the software systems to integrate the sensor data into the operations of EnergyAustralia, which runs the country’s biggest electricity distribution network. In dollar terms, the deal is small – just A$3.2 million (U.S. $2.2 million) – but significant in showing the viability of transforming analog electricity distribution systems into an intelligent network, according to Michael Valocchi, an executive with IBM’s (IBM) global energy and utilities unit.

“The electricity distribution operator will have a real-time view of the network and will be able to pinpoint outages quickly and reduce their length,” Valocchi told Green Wombat. “What I really like about this deal is that it starts to show and harden the message that smart grid is much more than automated metering. As you see more distributed energy and renewable energy out there, this type of sensor and this type of intelligence on the grid will help manage that.”

The sensors will be placed mainly at EnergyAustralia’s substations and around transformers, Valocchi says.

IBM had previously rolled out a smaller version of the smart grid system in Denmark. And in February the tech giant announced a deal to build a smart utility and water system for the Mediterranean island nation of Malta.  While overseas utilities have been quicker to smarten up their analog power grids, Valocchi says the United States should not be far beyond, especially as federal stimulus money for smart grids begins to flow.

California Senator Dianne Feinstein’s move to put a large swath of the Mojave Desert off-limits to renewable energy development is splitting the environmental movement and could derail some two dozen solar and wind power projects the state needs to comply with its ambitious climate change laws.

On the firing line are 17 massive solar power plants and six wind farms planned for federal land — land that would be designated a national monument under legislation Feinstein intends to introduce. The solar projects in question would be built by a range of companies, from startups BrightSource Energy and Stirling Energy Systems to corporate heavyweights Goldman Sachs (GS) and FPL (FPL), according to federal documents. (For the complete list, see below.)

The companies are among scores that have filed lease claims on a million acres of acres of desert dirt controlled by the U.S. Bureau of Land Management. California utilities PG&E (PCG) and Southern California Edison (EIX) have signed long-term power purchase agreements for some of the projects now in jeopardy and are counting on the electricity they would produce to meet state-mandated renewable energy targets. PG&E itself has filed a solar power plant land claim in the proposed national monument.

The area of the desert in dispute is some 600,000 acres formerly owned by Catellus, the real estate arm of the Union Pacific Railroad, and donated to the federal government a decade ago by the Wildlands Conservancy, a Southern California environmental group. About 210,000 of those acres are managed by the U.S. Bureau of Land Management, which opened part of the land to renewable energy projects.

“Many of the sites now being considered for leases are completely inappropriate and will lead to the wholesale destruction of some of the most pristine areas in the desert,” Feinstein wrote in a letter to Interior Secretary Ken Salazar released last week, notifying him that she will introduce legislation to designate the former Catellus lands a national monument. “Beyond protecting national parks and wilderness from development, the conservation of these lands has helped to ensure the sustainability of the entire desert ecosystem by preserving the vital wildlife corridors.”

The Catellus land controlled by the BLM forms something of a golden triangle between the Joshua Tree National Park and the Mojave National Preserve in Southern California and are particularly coveted for renewable energy development because of its proximity to transmission lines.

Alan Stein, a deputy district manager for the BLM in California, told Green Wombat that the solar and wind lease claims are in areas that are not designated as wilderness or critical habitat for protected species like the desert tortoise. “This is public domain land, ” he says.

Tortoises, however, are found across the Mojave, and battles over Big Solar’s impact on endangered wildlife are quietly brewing in several solar power plant licensing cases now being reviewed by the California Energy Commission.  Environmentalists find themselves walking a thin green line, trying to balance their interest in promoting carbon-free energy with protecting fragile desert landscapes and a host of threatened animals and plants.

Take BrightSource Energy’s Ivanpah 400-megawatt solar power plant complex on the California-Nevada border. The three solar power plants to be built by the Oakland-based company will supply electricity to PG&E and Southern California Edison. But the project will also destroy some 4,000 acres of desert tortoise habitat and at least 25 tortoises will have to be relocated – a somewhat risky proposition as previous efforts in other cases have resulted in the deaths of the animals.

On Wednesday, the California Energy Commission granted two national environmental groups – the Defenders of Wildlife and the Sierra Club – the right to intervene in the Ivanpah case. “Defenders strongly supports … the development of renewable energy in California,” Kim Delfino, California program director for Defenders of Wildlife, wrote to the energy commission in a Jan. 23 letter.  “Defenders has several serious concerns about the potential impacts of this project on a number of rare, declining and listed species and on their associated desert habitat and waters.”

Natural Resources Defense Council attorney Johanna Wald wrote a letter with the Wilderness Society expressing concern over the impact of Ivanpah project on the desert tortoise but also made a strong statement of support for renewable energy development. “Our public lands harbor substantial wind, solar, and geothermal resources,” wrote Wald, who serves on a state task force to identify appropriate areas for renewable energy development. “Developing some of these resources will be important to creating a sustainable energy economy and combating climate change.”

The big national enviro groups are working with the government and power plant developers to create zones in the Mojave where renewable energy projects would be permitted while setting aside other areas that are prime habitat and wildlife corridors. A similar effort is underway on the federal level to analyze the desert-wide impact of renewable energy development.

Local environmental organizations, however, have split with the Big Green groups over developing the desert and other rural areas. In San Luis Obispo County,  Ausra, SunPower (SPWRA) and First Solar’s (FSLR) plans to build three huge solar farms within miles of each other has prompted some local residents worried about the impact on wildlife to organize in opposition to the projects.

And some small Mojave Desert green groups pledge to go to court to stop big solar projects. “We don’t want to see the Endangered Species Act gutted for the sake of mega solar projects,” veteran grass roots activist Phil Klasky told Green Wombat last year for a story on the solar land rush in the Mojave. “I can say the smaller environmental organizations I’m involved with are planning to challenge these projects.”

It would be unwise to underestimate Klasky. In the 1990s, he helped lead a long-running  and successful campaign to scuttle the construction of a low-level radioactive waste dump in tortoise territory in the Mojave’s Ward Valley – now a prime solar spot.

Still, while California’s senior senator’s move in the Mojave may exacerbate rifts in the environmental movement over renewable energy, it also could galvanize efforts to resolve critter conflicts in a comprehensive way. Otherwise, environmentalists of varying hues may find themselves fighting each other rather than global warming.

Update: I just had a conversation with BrightSource spokesman Keely Wachs, who takes issue with my characterization that the Ivanpah project will “destroy” desert tortoise habitat. He points out that the company is taking care to minimize the impact of the power plant on the surrounding desert and that wildlife may still occupy the site. It would be more accurate to say that the project will remove desert tortoise habitat from active use during Ivanpah’s construction and operation.

(Below is a list of solar and wind projects that fall within the proposed Mojave national monument. Note: Solar Investments is a subsidiary of Goldman Sachs and Boulevard Associates is a subsidiary of FPL.)
