The twentieth century way of life has been made available, largely due to the miracle of cheap energy. The price of energy has been at record lows for the past century and a half.As oil becomes increasingly scarce, it is becoming obvious to everyone, that the rapid economic and industrial growth we have enjoyed for that time is not sustainable.Now, the hunt is on. For renewable sources of energy, for alternative sources of energy, for a way of life that is less dependent on cheap energy. 

  • Florida investors rent rooftops

    From The Washington Monthly

    By Mariah Blake

    This winter, as Congress was scrambling to pass the stimulus package, the bottom fell out of the renewable energy sector—the very industry that lawmakers have held out as our best hope of salvaging the economy. Trade groups like the American Wind Energy Association, which as recently as December was forecasting “another record-shattering year of growth,” began predicting that new installations would plunge by 30 to 50 percent. Solar panel manufacturers that had been blazing a trail of growth announced a wave of layoffs. Some have since cut their workforces in half, as stock prices tumble and plans for new green energy projects stall.

    But there is one place where capital is still flowing: Gainesville, Florida. Even as solar panels are stacking up in warehouses around the country, this city of 120,000 is gearing up for a solar power boom, fueled by homegrown businesses and scrappy investors who have descended on the community and are hiring local contractors to install photovoltaic panels on rooftops around town.

    One of those investors is Tim Morgan, a tall fiftysomething man with slicked-back hair and ostrich-skin boots who owns a chain of electrical contracting companies. His industry has been hit hard by the downturn, but he has a plan to salvage his business, which he explained over a drink at the Ballyhoo Grill, a gritty Gainesville bar with rusty license plates nailed to the wall and Jimmy Buffett blaring on the jukebox. Morgan intends to rent roof space from eighty Gainesville businesses and install twenty-five-kilowatt
    solar generating systems on each of them, for a total of two megawatts—a project that would nearly double Florida’s solar-generating capacity. He estimates the venture will cost between $16 million and $20 million and bring in $1.4 million a year. Already, he has lined up financing, found local contractors to do the installation, and staked claims to the rooftops of at least fifty businesses. “And we’re just one tiny player,” he told me. “Look around. You can see how fast this thing is going to move.”

    Indeed, around Gainesville similar projects abound. Paradigm Properties, a residential real estate company, plans to install photovoltaic arrays on fifty local apartment buildings and its downtown headquarters. Achira Wood, a custom carpentry outlet, is plastering the roof of its workshop—roughly 50,000 square feet of galvanized steel—with solar panels. Interstate Mini Storage is doing the same with its sprawling flat-roofed compound. Tom Lane, who owns ECS Solar Energy Systems, a local solar contractor, told me he’s planning to expand his staff from eleven to at least fifty. “The activity we’ve seen is just explosive,” he said. “I’ve been in the business thirty years and I’ve never seen anything like it.”

    Why is the renewable energy market in Gainesville booming while it’s collapsing elsewhere in the country? The answer boils down to policy. In early February, the city became the first in the nation to adopt a “feed-in tariff”—a clunky and un-descriptive name for a bold incentive to foster renewable energy. Under this system, the local power company is required to buy renewable energy from independent producers, no matter how small, at rates slightly higher than the average cost of production. This means anyone with a cluster of solar cells on their roof can sell the power they produce at a profit. The costs of the program are passed on to ratepayers, who see a small rise in their electric bills (in Gainesville the annual increase is capped at 1 percent). While rate hikes are seldom popular, the community has rallied behind this policy, because unlike big power plant construction—the costs of which are also passed on to the public—everyone has the opportunity to profit, either by investing themselves or by tapping into the groundswell of economic activity the incentive creates.

    Though Gainesville is the first to take the leap, other U.S. cities are also moving toward adopting feed-in tariffs. Hawaii plans to enact one this summer, and at least ten other states are considering following suit. Among them is hard-hit Michigan, where Governor Jennifer Granholm has promised that the policy will help salvage the state’s economy and create thousands of jobs by allowing “every homeowner, every business” to become “a renewable energy entrepreneur.” There is also a bill for a federal feed-in tariff before Congress.

    Could this approach help revive our renewable energy market, and give a needed jolt to the U.S. economy? There is reason to believe it could. In Germany, which pioneered the modern feed-in tariff, it has given rise to the world’s most vibrant green energy sector. More than forty countries, from Nicaragua to Israel, have followed Germany’s lead, often with dramatic results. Study after study has shown that not only do feed-in tariffs deliver more renewable energy than other market incentives, they do so at a lower cost. “People hesitate to call anything a panacea,” says Toby Couture, an energy and financial markets analyst at the Department of Energy’s National Renewable Energy Laboratory. “But if you’re interested in creating jobs, getting capital flowing, and expanding renewable energy, feed-in tariffs get the job done—often more cost effectively than other policies.”

    To understand why feed-in tariffs are potentially revolutionary, you first have to understand how they differ from the system we’ve been using to drive investment in renewable energy so far. For the last fifteen years, the United States has relied on a patchwork of state subsidies and federal tax breaks—mostly production tax credits for wind power, which let investors take write-offs for the energy produced. When Wall Street was riding high on mortgage-backed securities, this made green energy an appealing option for big banks, which funneled billions of dollars into sprawling wind farms as a way of lowering their taxes. But when the market collapsed and corporate profits dried up, so did the incentive to invest. Since last year, the number of tax equity investors—mainly big investment banks—sinking money into wind farms has dwindled from as many as eighteen to four, and the remaining players have scaled back.

    This tax-based system has other drawbacks as well. Because Congress has to renew the tax credits—and has often failed to do so—renewable energy is a risky market. Frenzied bursts of investment are followed by near-total collapse, a pattern that has hampered the growth of our domestic green manufacturing sector. Also, tax incentives (and the quota systems in place in about half of U.S. states) end up favoring large-scale projects, mostly monster wind farms concentrated in remote places like the Texas panhandle. This has been lucrative for the companies, like GE and Siemens, that build them, but of limited economic benefit to local communities. What’s more, a lot of energy is wasted transporting power from the sparsely populated areas where it’s produced to the cities and coasts—assuming it can be transported at all. Transmission lines are in such short supply that turbines (and occasionally entire wind farms) sometimes have to be shut down because of bottlenecks in the grid.

    Feed-in tariffs promise to solve many of these problems by encouraging small, local production, driven not by Wall Street banks but by ordinary entrepreneurs—a system that boosts efficiency and fortifies local economies.

    Feed-in tariffs are not a new idea. In fact the United States tried them once before, in the 1970s. At the time the global economy was in shambles, the result of OPEC choking off the world’s oil supply. In a bid to ward off future oil shocks, Congress passed the Public Utility Regulatory Policies Act of 1978 (PURPA), which required power companies to buy electricity from small renewable generators. This spurred a green energy boom, especially in California, which offered producers long-term contracts at rates that were tied to the then-soaring price of natural gas (specifically, they were linked to future-cost projections). Virtually all of the renewable generating power the state has today came online under the policy. More importantly, the technical breakthroughs made in California during this era helped give rise to the modern renewable energy industry.

    But this approach also had some glaring flaws, which came into focus in the early 1990s, when the price of natural gas tumbled. Rates for renewable energy sank so low that there was no incentive to invest, and the industry collapsed. Power companies were also stuck with high-priced contracts, which stirred a well of public resentment. Several key states, including California, rolled back the contract requirements, essentially taking the teeth out of PURPA.

    But not every nation had the luxury of cheap, abundant fossil fuels. Even in the 1980s and ’90s, when the United States was flush with energy, Germany was struggling to meet its demand—a by-product of its scant oil and gas reserves and the groundswell of opposition to nuclear power after the Chernobyl meltdown. One of the solutions the country settled on was dusting off the feed-in tariff model. The original German bill, passed in 1991, only created an incentive for wind and hydropower. Still, it doubled the share of renewable electricity the country produced, from 3 to 6 percent, over the next nine years. In 2000, the incentive was extended to all renewable energy sources. The pricing structure was also overhauled so rates were tied to the cost of production and varied by energy source—a key point of distinction from PURPA. The aim of the policy was to cultivate a broad enough portfolio of renewable options that Germany could one day replace fossil fuels entirely, and do so outside conventional energy markets. “Big power companies have too many vested interests against renewable energy,” explains Hermann Scheer, a member of the German parliament, who championed the policy. “They will never be the driving forces behind its development.”

    The policy has allowed Germany not only to meet but to exceed its renewable energy goals. Initially, the aim was to get 12 percent of its electricity from renewable sources by 2010. But it passed that milestone three years early, and has since reached the 15 percent mark—the most rapid growth seen in any country. By mid-century, Germany aims to increase that share to 50 percent. Already, the nation, which is about as sunny as Juneau, Alaska, is home to almost half the world’s solar generating capacity, and churns out more solar power than any country except Japan. Although it is half the size of Texas, and far less windy, it is also vying with the United States for the number one spot when it comes to generating capacity for wind power.

    The driving forces behind this boom are local communities and small entrepreneurs. If you travel the country top to bottom, you’ll see the signs of this everywhere, from the drizzly port of Hamburg, where wind turbines are tucked between stacks of rusty shipping containers, to villages in the Black Forest, where farmers are ripping out ancient waterwheels and replacing them with modern turbines. In Freiburg, a walled medieval city full of cobbled streets and Gothic spires, there are roof-mounted photovoltaic panels everywhere, from churches and schools to train stations and factories, even the local soccer stadium. Some residents have also found more creative ways to harvest energy. Among them is local architect Rolf Disch: his home, which looks like a squat upside-down rocket, has a billboard-sized solar array on the roof and wrap-around balconies with liquid-filled railings that double as solar heat collectors. It also rotates to follow the sun. All told, the building generates five times more electricity than it uses. Disch has also designed solar gas stations and a suburban housing development, where the homes act like mini power stations. But he is careful to note that his clients are not hippies or eco-rebels. “These are doctors, teachers, engineers,” he told me when I visited Freiburg last June. “In other words, ordinary people.”

    What inspires ordinary Germans to invest in renewable energy? Part of the answer is that it’s about as safe as government bonds—and brings a better return. Under the German system, renewable energy producers are given long-term, fixed-rate contracts, designed to deliver a profit of 7 to 9 percent. This makes green energy a secure bet for both investors and banks.

    T he German system contains another ingenious feature: every year, the rate paid for new contracts falls, so a company that installs a large rooftop solar array this year will lock in a rate that is nearly 20 percent higher than one that waits until 2011. This has two salutary effects. First, it creates an incentive for would-be entrepreneurs to get in the game as soon as possible, thereby spurring a rush of investment (which helps explain why Germany was able to meet its renewable energy targets three years early). Second, it forces the green energy sector to innovate. If they want to stay in business and hold on to their margins, manufacturers have no choice but to continually seek out new efficiencies.

    This combination of a fast-growing market and rapid innovation has turned the country into a green industry powerhouse. Germany is the leading destination for green capital, with $14 billion invested in 2007 alone. It is also a front-runner in green job creation. Some 300,000 people work in the nation’s renewable energy sector today. By 2020 green technology is expected pass the auto and electrical engineering industries to become the nation’s top employer, with more than 700,000 workers. One of the forces driving this growth is exports. In fact, many of the windmills and solar panels that are cropping up from New York to the Texas panhandle are made in Germany.

    The economic benefits of this green tech boom have reached into the poorest corners of the country, including ragged patches of former East Germany. The region between Frankfurt-Oder and Dresden was once as grim as the drabbest outpost in the American Rust Belt. But in recent years, a vibrant green energy corridor, known as “solar valley,” has sprung up amid the abandoned coal mines and shuttered factories. Thousands of workers from the defunct East German semiconductor industry (some of whom had languished for years on unemployment rolls) are now gainfully employed in solar panel factories.

    Most importantly, although Germany’s economy has been devastated by the downturn, its green energy sector continues to thrive. In fact, Ernst & Young recently ranked the nation number one on its index of most attractive markets for renewable energy investment. “Just as cash is king,” the report found, “feed-in tariffs are favored by investors,” especially in uncertain financial times.

    Y ou might expect that a system like this—one that allows countless independent producers to sell electricity at premium rates—would come with a hefty price tag. But that is not the case. Studies have shown that even though German-style feed-in tariffs encourage the use of relatively expensive forms of renewable energy, such as solar power, they produce power more cheaply on a watt-for-watt basis than other renewable energy policies. This is because there is less investment risk, and less risk means investors can get lower-interest loans for generating equipment. This is one reason installing a solar panel in Freiburg costs less than it does in San Francisco. Renewable energy producers are also willing to accept lower profit margins because the returns are all but guaranteed. In contrast, under other systems utilities are forced to pay hefty risk premiums. This is particularly true of the quota systems (known as renewable portfolio standards) that are in use in about half of U.S. states and some European countries.

    These findings are not lost on Germany’s neighbors. To date, at least eighteen of the European Union’s twenty-seven member states—along with some twenty-five countries, cities, and provinces elsewhere in the world—have adopted feed-in tariffs. Mario Ragwitz, who is spearheading a long-term EU study comparing renewable energy incentives, says three-quarters of the renewable electricity that the bloc produces each year is a direct result of this trend. “Almost everything Europe has when it comes to clean energy stems from the feed-in tariff policy,” he says. “No other system compares.”

    In some nations where feed-in tariffs have reached critical mass, there is evidence that they have actually driven down the overall price of electricity. This may seem counterintuitive—after all, renewable energy is more expensive on average than, say, coal power. But the price of electricity is often driven by natural gas, a costly and volatile fuel that is frequently used to meet peak power needs. If you have a large volume of renewable energy (particularly less-expensive wind power) you can cut your use of natural gas, bringing prices down across the board.

    I n the United States, tax credits and quotas are still the policies of choice. But this may be changing. While the stimulus package expands existing incentives, it also has some novel twists. Namely, in lieu of tax write-offs, companies that break ground on renewable energy projects (such as solar, wind, and geothermal plants) in the next two years can recover 30 percent of their project costs from the Treasury in the form of direct grants. This opens the renewable market to a wide range of players, rather than just big companies with outsized tax bills.

    Investors and industry analysts have hailed this as an enormous step forward—one that, in concept, could unclog the pipelines of capital and breathe life back into the renewable sector. “Theoretically, this approach could really supercharge the industry,” says Cai Steger of the Natural Resource Defense Council’s Center for Market Innovation. But they are divided over just how much investment it will attract. This is because, while the policy broadens the pool of potential investors, it doesn’t thaw the frozen credit markets, which have made it difficult to get financing for renewable projects (except in places where the return is guaranteed). Also, although the green energy measures in the stimulus package are longer term than past incentives (the production tax credits were extended for three years instead of one, as has often been the case in the past) they don’t entirely fix the quandary of market instability. Will the industry collapse again when the Treasury grants expire in 2010? Nobody really knows. Moreover, analysts expect the system will continue to favor large-scale projects. This means it is unlikely to spur the kind of small, local production, widespread economic development, and rapid job growth seen in places like Germany.

    O n this front, some lawmakers would like to see America give Europe a run for its money. “Why should Germany be dominating all this job creation?” Rep. Jay Inslee of Washington told me when I visited him on Capitol Hill in January. “It’s time for us to get in the game.” Last June, the Democratic congressman, who has long been pushing green energy as an engine of economic growth, introduced a bill for a federal feed-in tariff —part of a surge of interest in the policy reaching from California to Maine. In recent months, there has been a flurry of white papers, reports, and conferences on the topic. Interest is also growing in research circles. Toby Couture of the National Renewable Energy Laboratory says that six to eight months ago many of his colleagues didn’t even know the policy existed. Now, he adds, “Everyone on my team is asking, ‘Why aren’t we doing this?’”

    Congress, meanwhile, is clearing away some of the logistical stumbling blocks, like our nation’s aging, patchwork electric grid, which could make the intermittency of renewable energy difficult to manage, especially if large quantities come online at once. The stimulus package helps solve this problem by providing $11 billion to modernize our energy infrastructure and develop a “smart grid,” with advanced sensors and distributed computing capabilities, so it can instantly reroute power to meet demand or avoid system overloads. This should pave the way for a better integration of renewable electricity—and, perhaps, open the door to strong, consistent policy that channels America’s entrepreneurial drive into renewable energy.

    The drive is there waiting to be unlocked. Just ask Tim Morgan. As the sun dipped behind the live oaks outside Ballyhoo, and “Margaritaville” blared over the speakers, he let me in on the grander scheme behind his Gainesville venture. As he trolls the city for rooftops where he can install photovoltaic arrays, he’s purposely gravitated toward chain stores. That way as other cities and states adopt feed-in tariffs, he’ll have ready-made inroads. “I wanted the system to be scalable, so I can expand,” he explained. “If the incentives are right, there’s no reason there couldn’t be solar panels on every Walgreens and Sam’s Club across the country.”

    Will Tim Morgan turn out to be the Sam Walton of solar power? Who knows. But hearing his plan, I definitely had the sense he was a man on the ground floor of something big.

  • Rebuilding New Orleans to be energy efficient

    Related article from Renewable Energy News

    New Orleans is going green as it continues rebuilding after Hurricane Katrina — with a big assist from the U.S. Department of Energy’s National Renewable Energy Laboratory.

    Sprouting in once-flooded neighborhoods are some new energy-efficient homes featuring rooftop solar panels, extensive insulation and more efficient climate systems. These standards will be applied citywide in schools and hospitals, too.

    Many of the improvements are based on renewable energy programs and strategies provided by DOE and the laboratory.

    Nor are the energy-saving improvements limited to hurricane reconstruction. Even before Katrina, many of the city’s commercial buildings and dwellings were blighted. Entire neighborhoods were built decades ago without insulation and are subject to termite infestations.

    The lab’s commitment to demonstration projects and community partnerships has encouraged city officials to embrace renewable energy.

    Now the motto “Cleaner … Smarter” is stenciled on the city’s new buses that run on a 5 percent biodiesel blend, and New Orleans has been selected as one of DOE’s Solar America Cities.

    “New Orleans has an amazingly vibrant local culture,” says senior project leader Phil Voss, who returned to Golden in January after 18 months in New Orleans. He is the lab’s first energy expert to be embedded in a field project.

    “And until now, that same culture has not been open to many outside ideas – like energy efficiency.”

  • Mercury treaty puts more pressure on coal

    From the Guardian

    Environment ministers overcame seven years of obstacles today and committed to reducing the world’s mercury pollution.

    In a sign of America’s return to a global leadership role, United Nations environment ministers meeting in Nairobi agreed to take immediate steps to limit exposure to mercury.

    The White House said it would press hard for a legally binding treaty when negotiations get under way later this year.

    “The United States will play a leading role in working with other nations to craft a global, legally binding agreement that will prevent the spread of mercury into the environment,” said Nancy Sutley, chair of the White House council on environmental quality.

    The Bush administration had blocked international efforts to limit mercury – although such protections are in place in America.

    Mercury, which can travel thousands of miles from its original source, damages the central nervous system, and is especially dangerous to pregnant women and babies.

    The treaty will include measures to reduce the supply of mercury and its use in products, such as thermomenters, and processes, like paper making. It will also seek to cut back on mercury emissions from coal-fired power plants, which are responsible for about half of the world’s mercury pollution.

    The new-found consensus in Nairobi, which saw the US, India and China lifting their resistance to a binding global mercury treaty, raised hopes for progress later this year at the crucial UN meeting in Copenhagen on an international climate change deal.

    “There was a seismic shift from the American government from its previous position,” said Nick Nuttall, the spokesman for the UN environment programme. “It was clear from the beginning of this week that the US negotiators had been given a clear line from Washington, and indeed the White House, to come together with the rest of the world and do something.”

    “The US has taken a leadership role that will chart a new course on mercury protections around the world. We have set a strong example that is already influencing others to do the same,” said Susan Egan Keane, an analyst at the US National Resources Defence Council.

    Barack Obama had earlier taken a number of steps at home to break with the George Bush legacy on the environment – most notably restoring the power of government agencies to regulate carbon dioxide from power plants.

    The strong push from the US side in Nairobi this week evidently helped wear down resistance from governments such as China and India. China is heavily dependent on coal-fired power plants, while Indian manufacturers still use many processes that depend on the metal.

    The eight-point plan agreed on Friday calls for reduction in mercury emissions from power plants, and in its use in thermometers and other household products, as well as in plastics production and paper-making. It would cut down on the use of mercury in gold panning, a process that results in huge quantities of the heavy metal being washed into streams.

    Mercury is a naturally occurring element, but pollution has caused levels to rise sharply in many fish species, increasing the danger to humans that eat them.

    “Today the world’s environment ministers, armed with the full facts and full choices, decided the time for talking was over – the time for action on this pollution is now,” said Unep’s director, Achim Steiner.

    Formal treaty negotiations will get underway later this year, with a view to reaching a final agreement in 2013.

  • Fertiliser prices knock ethanol production

    Read related story from The Land
    For the past year the price of fertiliser has been skyrocketing in the United States, which lead to slow sales and increased stockpiles of fertiliser.

    The increase prompted many companies to decrease production.

    Last northern autumn prices began to come down, but farmers continued to wait to make fertiliser purchases in the hopes that prices would continue to go down.

    Now as planting time draws nearer, fertiliser manufacturers are claiming that delivery channels for fertiliser are unable to move product due to a full supply chain.

    According to Mosaic Company chief executive officer James Prokopanko warehouses at all levels – from distribution to retailer – are full.

    “I’m not going to forecast a shortage, but capacity is going to be ever more constricted,” Mr Prokopanko said.

    One of the big challenges to overcome, according to Mr Prokopanko, is the idling of railways that has occurred in response to the slowdown in commodity shipments.

    He says the railroad will need time to get equipment back in operation.

    Compounding the problem is the fact that many dealers are reluctant to mark down the price of fertiliser that they purchased last summer when prices were high.

    “It’s one thing to have high inventory,” said Mark Gulley, an analyst at Soleil Securities Corp in New York.

    “It’s another thing to have high-priced inventory.”

    The result in parts of the US are a wide variety when it comes to fertiliser prices.

    Due to the clogged supply chain Mmr Prokopanko says there could be a shortage that could limit farmers ability to get the fertiliser they need.

    It was estimated on January 6 that US farmers would plant 85 million acres of corn this season, but now with the fertiliser situation as it is, Mr Prokopanko says he expects farmers may plant only 82.5 million acres.

  • Brain cancer rise mysterious

    A BRAIN tumor has long been the most terrifying of malignancies, feared for its lethality and its position at the source of all thought and emotion. And now experts say the incidence of brain cancer may be on the rise.New studies of epidemiological data from this country and abroad indicate that the rise is especially dramatic among the elderly, but scientists say that even among the young, the rate of at least one rare form of brain cancer is surging.

    Other studies suggest that certain jobs may predispose workers or their children to brain cancer, and some researchers believe electromagnetic fields from power lines and power stations can help promote the growth of brain tumors, although many experts fiercely dispute the theory.

    Experts Are Concerned

    ”Wherever I go, people ask me whether there’s an increase in brain tumors,” said Dr. Paul L. Kornblith, chairman of the neurosurgery department at the Albert Einstein College of Medicine and Montefiore Medical Center in New York. ”And an awful lot of people in my field have the impression that there is a greater incidence than there was before. They are concerned about it.”

    Scientists emphasize that there is by no means an epidemic of brain cancer. They say the incidence of brain cancer remains very low for the population as a whole, accounting for about 1.5 percent of all malignancies. For most age groups, the rate of the two most common and deadly brain tumors, the gliomas and the astrocytomas, has been relatively stable for at least 20 years.

    Experts stress that trends in brain cancer are especially difficult to sort out, largely because the technology for diagnosing brain tumors has sharply improved over the last 15 years. With the aid of advanced imaging methods like CAT scans and magnetic resonance imaging, or MRI, doctors are now able to diagnose brain cancers that in the past might have mistakenly been described as strokes, senile dementia or other neurological disorders.

    ”If we agree that we are diagnosing a greater number of patients with brain tumors than before, a lot of that could be explained by the increased sensitivity of diagnostic tools,” said Dr. Edward H. Oldfield, chief of surgical neurology at the National Institute of Neurolgical Disorders and Stroke. ”When the CAT scan was introduced in the early 70’s there was a big jump in the detection of brain tumors, and the MRI has an even greater sensitivity for detecting small tumors.”

    Studies Track Increase

    Yet recent studies indicate that certain patterns in brain cancer trends cannot be dismissed as a result superior diagnosis.

    In one study, a new analysis of data collected by the National Cancer Institute’s nationwide cancer surveillance program, researchers at the National Institute on Aging in Bethesda, Md., have determined that among people over the age of 75, the incidence of brain tumorsmore than doubled from 1968 to 1985, the last year for which statistics are available. For people over 80, the rate of increase was even more shocking, soaring by 300 percent to 400 percent over the 17-year period, or by as much as 23 percent a year. ”Better diagnosis can explain some of the rise,” said Dr. Stanley I. Rapoport, chief of the laboratory of neuroscience at the Institute and the main author of the new report, which is to be published in The Journal of the National Cancer Institute. ”But something else is going on as well. Brain cancer in the elderly deserves more attention.”

    Further confirming the Rapoport results, scientists at the National Research Council in Washington, the Karolinska Institute in Stockholm and other institutions recently compared mortality figures from about 1968 to 1987 for the United States, Britain, Italy, France, West Germany and Japan. They found that among people 65 and older, deaths from brain tumors rose in all nations at up to 200 percent for the period.

    ”There’s a stunning increase in mortality” from brain tumors, said Dr. Devra Lee Davis, an author of the paper, which is to appear in the December issue of The American Journal of Industrial Medicine. ”It holds true for all countries, a very sharp increase in a relatively short period of time.”

    Dr. Davis said the increases in the six countries have continued long after the introduction of better imaging technology, indicating that improved diagnosis alone cannot explain the persistent rise.

    Another Possible Cause

    Among all age groups, the rate of a rare type of tumor, central nervous system lymphoma, which accounts for less than 5 percent of brain malignancies, has climbed 300 percent in 10 years. Experts say some of the rise is a result of AIDS, which makes people more susceptible to the malignancy. But others speculate that Epstein-Barr virus, which is becoming increasingly prevalent in the general population, may also be a cause.

    Beyond the risk of primary tumors originating in brain tissue, malignancies that have spread to the brain from elsewhere in the body are rising rapidly. ”The longer people are surviving from cancers of the breast, lungs and other organs, the more chance they have that some of their tumor cells will metastasize to the brain,” said Dr. William R. Shapiro, chairman of neurology at the Barrow Neurological Institute of St. Joseph’s Hospital in Phoenix. Doctors emphasize that even among the elderly, the risk of brain cancer is low, and that any rise in occurrence is modest compared, for example, with the steep climb in malignant melanoma and lung cancer among women.

    But they say brain cancer merits attention as an especially virulent disease for which there often is no treatment. The most prevalent types of brain tumors grow rapidly, spreading tumorous fingers into surrounding tissue and often killing within a year of diagnosis.

    ”Brain cancer is an awful, depressing cancer,” said Nigel H. Greig of the National Institute on Aging, a co-author of the Rapoport paper. ”It has one of the worst prognoses of all cancers. It’s almost invariably fatal. It’s lagged behind other cancers in chemotherapy and treatment, and survival time has not improved.”

    For that reason, experts say, it is worth trying to determine why brain cancer seems to be rising among older groups, and to eliminate whatever risk factors can be identified. Dr. Davis says that to understand why brain tumors are on the rise in the elderly, researchers must consider the past.

    ”You must look at those aspects of the world that changed 30 or 40 yers ago, because the latency period for brain cancer is that long,” she said.

    Speculating on such aspects, she points out that several decades ago, many more people worked in industrial, blue-collar jobs than do now, and that factories are often full of hazardous chemicals, running the gamut of the periodic table. ”There’s no question that proportionally more people used to work in dirtier places,” she said.

    The high proportion of factory workers may partly explain why brain tumors are now showing up in many industrial nations. Assuming the workplace is now cleaner than it was, Dr. Davis said, the incidence of brain cancer may begin to drop in the future. But she believes that other chemicals in the environment, like pesticides, will compensate for any improvements in the workplace.

    Dr. Davis believes that poor diet may be part of the reason for the rise in brain cancer. In the past, she said, people tended to pickle their meats and fish with suspected carcinogens like nitrites, and they ate few fresh vegetables and fruits, which contain anti-oxidants and other compounds thought to act as anti-cancer agents. Other researchers note that in the past, doctors and dentists were more cavalier in using X-rays and other forms of high-energy, or ionizing, radiation, now known to mutate DNA and wreak destruction in cells.

    A number of researchers are now investigating the possibility that even low-energy, or non-ionizing, radiation, may somehow promote the growth of brain tumors. They contend that electromagnetic fields from power lines, power stations and even common household appliances can be a health hazard. But many experts dispute those assertions. They say that, unlike ionizing radiation, which strips apart atoms and damages DNA, electricity is non-ionizing and is not thought to mutate genetic material. Nevertheless, some experts suggest electromagnetic fields could subtly increase the risk of cancer, particularly high-voltage currents and alternating currents generated by large power stations and substations.

    Writing in a recent issue of The New Yorker, the journalist Paul Brodeur discussed an apparent cluster of brain tumors on a street in Guilford, Conn., near a power substation. In a report in May, the Environmental Protection Agency said that there was a possible link between cancer and low-level electromagnetic fields, but that there still was not enough evidence to conclude that the fields directly caused cancer. In one study, Dr. David A. Savitz, an epidemiologist at the School of Public Health at the University of North Carolina in Chapel Hill, and colleagues considered all cases of childhood cancer from 1976 to 1983 in the Denver area.

    Samples Are Small

    They concluded that children who live near power lines that expose them to powerful electromagnetic fields had a 50 percent greater chance of developing brain tumors than those who did not live near power lines. But they said the samples were small and other potential health hazards in the environments considered had not been ruled out. Many experts insist the studies are inconclusive and contradictory. ”People are being very much alarmed over something for which there is no real evidence whatsoever,” said Dr. Eleanor R. Adair of the John B. Pierce Laboratory at the Center for Research in Health and the Environment, an affiliate of Yale University. ”Electricity has been around for a long, long time, and people’s life expectancy has nearly doubled since the invention of the light bulb.”

  • Wind powering ahead

    As RenewableEnergyWorld.com reported last week, the U.S. wind energy industry shattered all previous records in 2008 by installing 8358 MW of new generating capacity, according to the American Wind Energy Association (AWEA).

    Increasing total installed wind capacity by 50%, AWEA says the combined development channeled investment of some US $17 billion into the economy.

    The share of domestically manufactured wind turbine components has grown from under 30% in 2005 to about 50% in 2008 and manufacturers announced, added or expanded 70 new facilities in the past two years, including more 55 in 2008.

    However, warning of an uncertain outlook for 2009 due to the continuing financial crisis, AWEA noted that, towards the end of the year, financing for new projects and orders for turbine components slowed to a trickle and layoffs began to hit the wind turbine manufacturing sector.

    Nonetheless, with a total installed capacity of 25 GW installed, the U.S. has now officially overtaken Germany, with 24 GW of wind.

    Statistics released this week by the European Wind Energy Association (EWEA) show that 43% of all new electricity generating capacity built in the European Union last year was wind energy, more than all other technologies, including gas, coal and nuclear power.

    In 2008, a total of 19,651 MW of new generating capacity was installed across the economic bloc. Of this, 8484 MW was wind, 6932 MW of gas with a 35% share, 2495 MW of oil, a 13% share and 4%; 762 MW of coal.

    A total of 64,949 MW of wind capacity was operating in the EU by the end of 2008, 15% higher than in 2007 and a total of some 160,000 workers were employed directly and indirectly in the sector. Investments in the sector came in at about €11 billion in the EU as a whole in 2008.

    Germany has a narrow lead, with 1665 MW installed against Spain’s 1609 MW. In 2008 Italy added 1010 MW to reach a total of 3736 MW; France 950 MW to reach 3404 MW and the UK, 836 MW to reach 3241 MW. EWEA says that, overall, 2008 saw a much more balanced expansion led by France, the UK and Italy, part of a “second wave” of countries that are providing real momentum to the surge in wind energy. Together with the Netherlands, Portugal, Sweden and Ireland, ten EU Member States — over one-third — now have more than 1000 MW each. Austria and Greece follow close behind with 995 MW and 985 MW respectively. (View the charts below, which show the top 10 countries for installed capacity and for new capacity in 2008.)

    Furthermore, a distinct “third wave” became visible for the first time in 2008 as the new Member States had their strongest year ever, EWEA says. Hungary doubled its capacity to 127 MW and Bulgaria tripled its capacity from 57 MW to 158 MW. Poland, one of the fastest growing younger markets, now has 472 MW up from 276 MW. Outside the EU Member States, Turkey tripled its wind energy capacity from 147 MW to 433 MW.

    In terms of offshore wind energy, 357 MW of capacity was added in 2008, to reach a total of 1471 MW. Nearly 2.3% of total installed EU capacity is now offshore.

    Christian Kjaer, EWEA chief executive, observed: “The figures show that wind energy is the undisputed number one choice in Europe’s efforts to move towards clean, indigenous renewable power.”

    He added: “Wind energy is an example of an intelligent investment that puts EU citizens’ money to work in their own economies rather than transferring it to a handful of fuel-exporting nations.”

    With close to a third of all new capacity in 2008 installed in Asia, China also added about 6.3 GW, reaching a total of over 12 GW installed. China’s total capacity doubled for the fourth year in a row and in its response to the financial crisis, the Chinese government has identified the development of wind energy as one of the key economic growth areas.

    “These figures speak for themselves: there is huge and growing global demand for emissions-free wind power, which can be installed quickly, virtually everywhere in the world,” said Steve Sawyer, secretary general of Global Wind Energy Council (GWEC).

    “The 120 GW of global wind capacity in place at the end of 2008 will produce 260 TWh and save 158 million tonnes of CO2 every year,” he continued.

    GWEC’s chairman, Professor Arthouros Zervos said, “Wind power is often the most attractive option for new power generation in both economic terms and in terms of increasing energy security, not to mention the environmental and economic development benefits. The wind industry also creates many new jobs: over 400,000 people are now employed in this industry, and that number will be in the millions in the near future.”
