  • France Sets Ambitious Renewable Energy Targets

    "These targets mark a new era in the development of wind and solar power in France, and though they are ambitious, they can be achieved," Jean-Michel Parroufe head of the renewable energy division at the French Environment and Energy Management Agency (Ademe, Agence de l’Environnement et de la Maîtrise de l’Energie), told RenewableEnergyAccess.com.

    He said the plan would change the structure of France’s primary energy consumption — 275 million TOE (tons of oil equivalent) in 2006 — so that 20 percent would come from renewables, 25 percent from nuclear and 55 percent from fossil fuels by 2020, saving 20 million tons of oil.

    "From now on a bigger range of renewable energies, and not just biomass, will help meet the challenge of fighting global warming in France," Parroufe said.

    Parroufe, however, admitted it would not be easy for France to reach the target for wind.

    With just 810 MW of installed capacity, France is the third biggest market in Europe behind Germany with 2233 MW and Spain with 1587 MW.

    Installed wind capacity has been growing rapidly, doubling in 2004 and also in 2005 following a change in the law that had prohibited the state electrical company EDF Electricity France from buying electricity from wind parks over 12 MW.

    According to Parroufe, the most difficult part of meeting the wind target will be "finding enough good sites for the wind turbines because they shouldn’t spoil the landscape. It is a big target but we believe the right financial and legal framework is in place and we can make a leap forward in wind power," he said.

    The government has already laid solid foundations for growth in renewables by introducing more favorable feed-in tariffs for electricity from wind and solar power in July 2006 as well as tax breaks.

    As a result of the tax breaks, solar thermal systems grew by 80 percent in 2006 to reach 210 MW of installed capacity.

    Growth in PV installed capacity was 150 percent in 2006 boosted by a base feed-in tariff of 30 cents per KW/h for PV electricity in cities, said Rachel Massion from Enerplan, the Professional Association for Solar Energy [Association Professionelle de l’Energie Solaire].

    "We expect the same sorts of figures this year and in the future," Rachel Masson told RenewableEnergyAccess.com. "Photovoltaics are growing at different rates in different parts of the country depending on the policies of the local authorities."

    The Pays de Loire has become the leader in France with 1.4 MW of installed capacity followed by the Languedoc Rousillon, which has 1.18 MW because of special incentives for integrating solar panels into buildings.

    Also, the city of Narbonne plans to build a 9 MW PV station to supply energy for public buildings and street lighting.

    In spite of the growth in the wind and solar sectors, biomass will continue to provide the lion’s share of renewables in France even in 2020, Parroufe said.

    With 9.3 million TOEs in 2006, France is the biggest consumer of fuel wood in Europe after Sweden and Finland: more than 40 percent of all domestic heating systems in the country today use wood as fuel — and the number is growing.

    However, Parouffe said that expanding the use of biomass would require setting up a better network for collecting wood from the country’s forests.

    Other measures that the French government has announced on the renewable front include huge new investments in renewable energy research, like developing second generation biofuels.

    To boost the use of biogas, in 2006 the government increased the price by 50 percent as an incentive for drivers to use cleaner cars, such as electric and hybrid models.

    Also, energy performance certificates recording the carbon emissions of new cars became obligatory in May 2006 and financial incentives were introduced to make cars with low carbon emissions more attractive.

    The President of France Nicolas Sarkozy announced the new push for more renewables and more energy-efficiency to fight climate change in October following a three-month consultation period with representatives from environmental, business and social groups.

    He said that cutting carbon emissions would be factored in to all government decisions in the future, including the construction of new buildings and the handling of waste.

    The French parliament is set to pass the law in 2008.

  • Scientists Test Sonic Levitation on Goldfish

    Wenjun Xie and his team of colleagues used ultrasonic fields in their testing to keep a myriad of small animals in levitational stasis. Scientists were able to successfully levitate beetles, ants, spiders, ladybugs, tadpoles and fish between the sound wave emitter and reflector that comprise the device. While the ants, ladybugs and other insects were successfully levitated for over 30 minutes apiece without harm, the fish used in the experiment perished despite the scientists’ attempts to add water to the field with a syringe.

    While the team has tested the levitation equipment on small quantities of mercury and iridium, the heaviest known liquid and solid respectively, this is the first time it has been used to levitate living creatures. The initial aim of the project was to devise a way to levitate hazardous materials that could corrode containers or for whatever reason aren’t conducive to storage. And while the successful levitation of hazardous materials could prove useful for the production of pharmaceuticals and other industries that involve volatile substances, Xie says that the levitation of animals could open up a whole new realm of possibilities for such technology:

    Our results may provide some methods or ideas for biology research. We have tried to hatch eggs of fish [during] acoustic levitation.

    Results for the study were published in the online periodical Applied Physics Letters on November 20th.

  • Lovins reveals alternative oil plan

    Energy guru Amory Lovins lays out his plan for weaning the US off oil and revitalizing the economy in the process at the Technology, Entertainment and Design conference in Monterey, California. It’s the subject of his book Winning the Oil Endgame, and he makes it sound fairly simple: On one hand, the deadly risks of continued dependency, and on the other, some win-win solutions.

    The basis of his approach is that peak oil and climate change are engineering problems, not moral ones and that we simply need to think hard to come up with solutions. One of his most accessible solutions is to reduce the weight of automobiles by more than half. Currently most cars weigh at least ten times the human that drives them. This means that ninety percent of the energy they consume is used to drive the car, not the passenger around. 

  • Cell death may keep us young

    As the American population grows older, questions regarding the aging process and how it can be positively influenced are increasingly becoming the focus of scientific research and public interest. The age-related accumulation of proteins and lipids damaged by chemically aggressive forms of oxygen is considered by most in the geriatrics field to be a normal part of the aging process. As a result in most age-associated diseases, such as Alzheimer’s, damaged proteins accumulate in excessive amounts, which leads to progressive cell death in the brain.

    All cells undergo autophagy — literally self-eating, — which requires the assembly of specialized vesicles called autophagosomes. These vesicles surround or engulf damaged cellular proteins or structures and then traffic the "bagged garbage" to a second group of vesicles, which disposes of the trash with the help of digestive enzymes. This process can be enhanced when animals are placed on a calorie-restricted diet, a regime known to extend lifespan.

    "The activation of autophagy facilitates the removal of damaged molecules that accumulate during cellular aging," says Finley. "This may be particularly important in the nervous system since neurons produce damaged molecules at a much higher rate than most cell types." Keeping cells free of damaged molecules is critical for neurons because unlike many cells, they do not divide or replace themselves once created at birth. "They rely on autophagy together with other clearance and detoxification pathways to keep themselves healthy and functioning for decades," explains Finley.

    For their studies, the Salk researchers turned to the fruit fly Drosophila, a powerful model organism, whose genetics can easily be manipulated. When initial experiments indicated that the expression of several autophagy genes decreased over the normal lifespan of fruit flies, the Salk researchers focused on one particular protein, Atg8a. This protein is an essential component needed for the formation of new autophagosomes. Finley and her team found that levels of Atg8a were significantly reduced by four weeks of age, a time when the flies are considered middle aged. At the same time, protein aggregates were not efficiently cleared by the cellular clean-up crew and started to accumulate.

    Without Atg8a, things went from bad to worse. Damaged proteins tagged for degradation started to pile up early and life expectancy plummeted. "The abnormal accumulation of protein aggregates had striking similarities to those seen in the most common human neurodegenerative diseases," says first author Anne Simonsen, Ph.D., a visiting scientist from the University of Oslo, Norway.

    When the researchers kept the neuronal levels of Atg8a high, the genetically engineered flies were spared the ravages of time. Promoting the pathway not only prevented the accumulation of protein aggregates but also significantly extended the average lifespan. "Our experiments show for the first time genetically that autophagy can sequester and eliminate misfolded and damaged proteins, which accumulate in neurons as normal part of the aging process," says Simonsen, "but most importantly they demonstrate that enhancing the clearance of damaged proteins and protein aggregates increases longevity."

    Insulin signaling and caloric restriction are two major determinants of longevity and they also impact the activity level of autophagy. Therefore, regulating autophagy, the pathway that directly does the cleanup work, may be the key factor in controlling the aging process, the researchers say. "By maintaining the expression of a rate-limiting autophagy gene in the aging nervous system there is a dramatic extension of lifespan and resistance to age-associated oxidative stress," says Finley.

    Researchers who also contributed to the study include post-doctoral researcher and co-first author Robert C. Cumming, formerly in the Cellular Neurobiology Laboratory at the Salk Institute and now at the University of Western Ontario, Canada, and researchers Andreas Brech, Ph.D., and Pauline Isakson, Ph.D., both at the University of Oslo, Norway, and professor David R. Schubert in the Cellular Neurobiology Laboratory.

  • The Return of the Bread Riot

    Italy is not the only country experiencing growing political turbulence over the cost of staple foods. Last January, 70,000 people marched through the streets of Mexico City in a protest that has become known as the "tortilla riot." In response to these demonstrations, president Felipe Calderon signed an agreement to stabilize tortilla prices, which have skyrocketed more than 700% since 1994, the year that the North American Free Trade Agreement became law. After NAFTA took effect, many Mexican peasants were pushed off their land as cheap U.S. corn flooded the now tariff-free domestic market. Now that many American farmers are turning over significant portions of their corn harvest to the production of ethanol, Mexican consumers have no hedge against rising international corn prices.

    Where are such apparently isolated protests leading? It might be useful to get some historical perspective by considering one of the world’s most famous bread riots. On the morning of October 5th, 1789, a small girl began banging a drum and chanting a protest in one of Paris’s markets. According to the historian George Rudé, this protest quickly drew a large crowd of sympathetic women, who set out together on a march to make their complaint heard to the royal household in Versailles. Their numbers grew quickly to six or seven thousand; as they marched, the town guards were disarmed and their weapons were handed to men who followed the crowd of enraged women through the streets. We all know where this protest led ultimately.

    Yet the march on Versailles, like the storming of the Bastille earlier that year, was motivated not by anger over the conspicuous consumption of royals like Marie Antoinette, but rather by the far more immediate issue of the cost of bread. A laboring family of four in Paris ate 1.2 tons of grain a year in this period, 80 percent of which had to get to the city from the surrounding Paris basin on a poorly maintained road network. In the 1780s a series of floods in this area led to poor harvests, provoking soaring bread prices. By 1789, a worker’s daily bread took nearly 90 percent of her or his income. The demand for bread was central to practically all the journées, the popular insurrections and demonstrations that broke out repeatedly in Paris between 1789 and 1795. Women, on whose shoulders the crushing burden of domestic economy rested, were pivotal catalysts and participants in these demonstrations.

    Of course, nothing like this could happen today, right? The past decade and a half has seen a global wave of democratization, a vital hedge against famine according to the economist Amartya Sen. In addition, we’re blessed with a highly flexible food production and distribution system, the product not simply of a few decades of globalization but also of the thoroughgoing transformation of agriculture wrought by the Green Revolution following the 1950s. There are signs, however, that the energy-intensive practices of industrial agriculture spread around the world by the Green Revolution are not sustainable. As Michael Pollan recently argued in the New York Times, the mysterious disappearance of bees over the last year and the growth of drug-resistant Staphylococcus bacteria (which is now killing more Americans each year than AIDS) are both signs of the precariousness of the vast monocultures on which our current food system is based. According to Pollan, "whenever we try to rearrange natural systems along the lines of a machine or a factory, whether by raising too many pigs in one place or too many almond trees, whatever we may gain in industrial efficiency, we sacrifice in biological resilience."

    As important as these symptoms of a brewing crisis are, however, one doesn’t have to go as far as a hospital ward or an almond grove to get a sense of the unsustainability of the global agricultural system. A trip to the local supermarket to buy pasta will suffice. The rising cereal prices that drew protests in Italy and Mexico this year are the concrete harbingers of a calamity in the making. Over the last year, the food price index of the United Nations’ Food and Agriculture Organization rose by more than 40 percent, adding to a significant increase of 9 percent in 2006. According to the head of the FAO, Jacques Diouf, prices of wheat and oilseeds are at record highs; wheat prices have risen by $130 a ton, or 52 percent, since a year ago. In tandem with this inflation in the cost of staple cereals, reserves have become severely depleted. World wheat stores declined 11 percent this year, to the lowest level since 1980. That corresponds with 12 weeks of the world’s total consumption. There are only 8 weeks of corn left.

    Joachim von Braun, the head of the International Food Policy Research Institute, recently pointed out that crises have not materialized despite these dwindling supplies because states have literally eaten into their national grain stocks. According to von Braun, this situation may change soon because China, in particular, has nearly exhausted its supplies. In a speech in Beijing, von Braun stated that "over the next 12 to 24 months we are in a fairly risky situation. Large consuming nations, particularly China, will feel pressed to enter international markets to bid up prices to unusual levels." Chinese consumers are already facing galloping food inflation. According to a local paper quoted by the Manchester Guardian, three shoppers died recently in a stampede at a supermarket that was offering discounted rapeseed oil. With its massive foreign exchange reserves, China could potentially buy the global food crop many times over, driving international commodity prices through the roof.

    Just as was true in late-eighteenth century Paris, rising food prices are also related to climatic conditions. The early ­ and still relatively mild ­ effects of global warming have seriously damaged crop yields in breadbasket regions such as Australia and Ukraine in recent years. As S. Mark Howden of Australia’s Commonwealth Scientific and Industrial Research organization pointed out recently, "If there’s a significant change in climate in one of our high production areas, if there is a disease that affects a major crop, we are in a very risky situation."

    And, just as in the days of the French Revolution, it is the poor who will suffer the most from the spiraling cost of food. International aid agencies are having trouble keeping up with their shipments of food not just as a result of the inflated price of basic foodstuffs, but also because it has become far more expensive to transport food around the world given the surging value of petroleum. High oil prices also directly affect agriculture and, with it, food stocks, because petroleum is a vital ingredient of both fertilizers and pesticides, as well, of course, as being necessary to run the tractors and diesel pumps that are essential to industrial agriculture the world over. In addition, the threat of climate change is affecting poor countries in another way: as bio-fuels have been embraced as an important alternative to petroleum, food and fuel have entered into direct competition. According to a recent article in the Guardian, for example, Bangladeshi officials report that the price of cooking oil – of which it imports 1.2 million tons a year – has almost tripled in the past two years because it is now valued as an alternative to diesel oil.

    Of course it’s hard to say exactly how these disturbing trends will work out, but it’s unlikely that there is going to be an easy resolution. The rising cost of oil, one of the central catalysts of the crisis, is not a product of a political showdown as in the 1970s, but rather of speculation prompted by increasingly tight supplies. Moreover, short-term thinking is not likely to resolve our problems. The specter of famine may, for example, lead farmers the world over to expand crop production to ecologically sensitive or otherwise marginal areas. Yet although this may solve a potential crisis in the short term, it obviously does not represent a viable solution to the gathering crisis of the global industrial agricultural system. A more sustainable approach is suggested by FAO head Jacques Diof. With oil and food prices at near record highs, Diof recently argued that rich countries should stop sending food aid to poor nations and should instead concentrate on helping farmers grow food locally. Mr. Diof’s plan echoes the call of the international organization Via Campesina, which has made food sovereignty a cornerstone of its battle for peasant rights.

    Until now, however, such an approach has fallen on deaf ears in the halls of powerful international institutions such as the World Trade Organization, which have been dominated by the notion of food security advanced by the US, which argues, as always, for free trade since its industrially produced food products have until now been able to undercut the prices of all competitors on international markets. The result has been policies of food dumping, slashing of price supports that keep small farmers solvent, privatization of credit, and the patenting of crop genetic resources that have combined to push millions of farmers off their land and into the metastasizing mega-cities of the global South. Agriculture is now one of the most monopolistic of industries, with a handful of giant transnational corporations like Monsanto controlling both ends of the production process. Mr. Diof’s call for food sovereignty thus implies a wide-ranging transformation of the central institutions of globalization and, indeed, of the entire system of globalized industrial agriculture.

    With the contradictions of the industrial food system piling up to potentially deadly effect, it is high time we rejected this unsustainable model of globalized food and turned instead to the more sustainable model of local production and food sovereignty championed by organizations like Via Campesina. Organizing a local pasta strike might be a good if humble way to make this point. One can only hope that it will not take bloody bread riots and large-scale famines to push the world down a more sustainable path.
