Siemens to stop selling turbines for new coal-fired power plant projects FacebookTwitterLinkedInEmailPrint分享Reuters:Siemens Energy, which builds steam turbines for power plants, will no longer take on new business to supply coal-fired powered stations, it said on Tuesday, making it the latest firm to scale back fossil fuel-related operations.Selling turbines to coal-fired power plants accounts for a low single-digit percentage of the company’s sales, or roughly 820 million euros ($970 million) based on 2020 figures. It has said the business is profitable.Siemens Energy will still meet existing commitments, including placed bids, and honour service contracts for combined heat and power stations.Siemens Energy, which owns 67% of wind turbine maker Siemens Gamesa, makes about 30% of its sales by catering to fossil-fuel power stations, mostly gas, where it competes with General Electric and Mitsubishi Heavy Industries.Fourth-quarter earnings before interest, tax and amortisation (EBITA) before special items fell 87% to 70 million euros ($83 million) due to impairments and restructuring costs.[Christopher Steitz]More: Siemens Energy drops most coal business following spin-off
Dams have a deleterious affect on water quality and on fish habitat and passage. Indeed, wild salmon numbers in the Pacific Northwest’s Columbia River basin are down some 85 percent since the big dams went in there a half century ago. Pictured: the world famous Hoover dam, built in 1936. Photo Cred: iStockPhoto/ThinkstockDear EarthTalk: How is it that dams actually hurt rivers?— Missy Davenport, Boulder, CODams are a symbol of human ingenuity and engineering prowess—controlling the flow of a wild rushing river is no small feat. But in this day and age of environmental awareness, more and more people are questioning whether generating a little hydroelectric power is worth destroying riparian ecosystems from their headwaters in the mountains to their mouths at the ocean and beyond.According to the non-profit American Rivers, over 1,000 dams across the U.S. have been removed to date. And the biggest dam removal project in history in now well underway in Olympic National Park in Washington State where two century-old dams along the Elwha River are coming out. But why go to all the trouble and expense of removing dams, especially if they contribute much-needed renewable, pollution-free electricity to our power grids?The decision usually comes down to a cost/benefit analysis taking into account how much power a given dam generates and how much harm its existence is doing to its host river’s environment. Removing the dams on the Elwha River was a no-brainer, given that they produced very little usable electricity and blocked fish passage on one of the region’s premiere salmon rivers. Other cases aren’t so clear cut.According to the Hydropower Reform Coalition (HRC), a consortium of 150 groups concerned about the impact of dams, degraded water quality is one of the chief concerns. Organic materials from within and outside the river that would normally wash downstream get built up behind dams and start to consume a large amount of oxygen as they decompose. In some cases this triggers algae blooms which, in turn, create oxygen-starved “dead zones” incapable of supporting river life of any kind. Also, water temperatures in dam reservoirs can differ greatly between the surface and depths, further complicating survival for marine life evolved to handle natural temperature cycling. And when dam operators release oxygen-deprived water with unnatural temperatures into the river below, they harm downstream environments as well.Dammed rivers also lack the natural transport of sediment crucial to maintaining healthy organic riparian channels. Rocks, wood, sand and other natural materials build up at the mouth of the reservoir instead of dispersing through the river’s meandering channel. “Downstream of a dam, the river is starved of its structural materials and cannot provide habitat,” reports HRC.Fish passage is also a concern. “Most dams don’t simply draw a line in the water; they eliminate habitat in their reservoirs and in the river below,” says HRC. Migratory fish like salmon, which are born upstream and may or may not survive their downstream trip around, over or through a dam, stand an even poorer chance of completing the round trip to spawn. Indeed, wild salmon numbers in the Pacific Northwest’s Columbia River basin are down some 85 percent since the big dams went in there a half century ago.While the U.S. government has resisted taking down any major hydroelectric dam along the Columbia system, political pressure is mounting. No doubt all concerned parties will be paying close attention to the ecosystem and salmon recovery on the Elwha as it unfolds over the next few decades.CONTACTS: American Rivers, www.americanrivers.org; HRC, www.hydroreform.org.EarthTalk® is written and edited by Roddy Scheer and Doug Moss and is a registered trademark of E – The Environmental Magazine ( www.emagazine.com).

The Quest for a Petroleum Free LawnIt’s early morning and the neighbors are still asleep when I roll the mower out of the garage. I quickly position the machine to make the first pass and I’m off, grass flying and weeds tumbling. Half-an-hour later I’m starting to see progress. Half of my front yard looks as tidy as a new Marine’s head. The neighbors are still asleep. The birds are still chirping. The symphony of a rural morning is barely interrupted by the soft, sewing machine-like hum of my reel mower.For the sake of full disclosure I will state this up front. I think mowing grass is a complete waste of time. It’s not that I mind the work, that I don’t like to be out in the sun, get dirty or break a sweat. It’s just that the mindless riding in circles, week after week, summer after summer that produces nothing besides giving my lawn the awkward nakedness of a freshly shorn sheep makes no sense to me.Over my years of mowing grass I’ve also become conscious of another big, dirty fact. Lawn care requires oil. Lots of oil. It’s a vicious little cycle. The petroleum-based herbicides and fertilizers make your lawn grow so well you have to mow more which means pouring more oil into that gasoline-powered lawn machine of yours. The EPA estimates the mowing part alone uses 800 million gallons of gas in the U.S. each year. In fact according to their estimates 17 million more gallons of gas are spilled while we’re refueling our mowers (the oil it takes to make that much gas is as much as the Exxon Valdez spilled). The petroleum consumed in lawn care isn’t limited to the $4 a gallon gas we put into our mowers. Remember all the watering and applying pesticides and fertilizers and taking grass clippings to the landfill? Those products and processes are using as much oil as the act of mowing itself. Sounds like the value our culture places on a beautiful lawn was dreamed up in the marketing department of a petroleum company.The environmental impact doesn’t end with oil consumption. Most powered lawn tools have little or no emissions control equipment. The EPA quantifies the pollution they create at nearly 125 pounds of CO2 and other pollutants per mower each season. To put that number into perspective for every hour that your mower runs it’s like eleven cars are being driven at interstate speeds. Is it possible that your lawn care is outweighing the fact that you own a Prius?You would think that a person who has my reservations about mowing would live in an apartment, but my rural home is surrounded by acres of woods, orchards, gardens and grass. Literally acres. I fought back, planted flower beds, expanded the garden, let as much of my property go “natural” as possible, but in the end there was a certain amount of grass that had to be maintained to keep the skunks and ticks at bay. Factor in the orchard, the outbuildings and the walking paths and I was still stuck with about an acre and a half left to mow.According to the experts I’m the wrong person to use a reel mower. My yard is too big and too bumpy. I have too many trees to mow around that drop branches that jam the reel. According to them I’m probably morally justified in continuing to use my gasoline mower. I could keep riding and still sleep at night. But something about all the oil that was going into my lawn nagged at my conscious. So last spring after doing the research and considering the options I downgraded from a riding mower to a walk behind reel mower and spent the summer with a human powered yard.Green living Web sites and retailers trying to sell you a reel mower can spend hours extoling the virtues of the human-powered machines. They cut grass cleaner, leaving the grass healthier, more resistant to disease, pests and drought and spray your yard with a fine coat of mulch as they go. I have to admit in that first summer I didn’t notice any difference in how my lawn looked. Then again, I couldn’t care less if the neighbors admire the PGA qualities of my crab grass.But I also discovered that using a reel mower gave me benefits beyond aesthetics or the money I was saving from not buying gasoline. I never used a stopwatch, but in the end, mowing with a reel mower seemed just as fast as my riding mower. This factors in not only the “seat time” involved in mowing but also the time spent on “support activities.” No dead batteries as you’re scrambling to beat the rain. No broken belts at 4:50 p.m. on a Saturday afternoon. No special trips to town for mower gas. And I was getting exercise. Health experts estimate using a reel mower burns about 375 calories an hour. Every spring my exercise time gets crammed to the edge of my schedule by mowing. By using the reel mower I was getting both done at the same time.Reel mowers are good for the environment and allow you to exerciseThen there were the small things. I didn’t have a front row seat to breathing in lawn mower exhaust. My clothes didn’t smell like gas fumes. I wasn’t exposed to gas or oil spills. I didn’t have to wear ear plugs for hours. The quietness of the mower allowed nature to continue on its business uninterrupted and allowed me to better observe it. Mowing had ceased to be an industrial activity in spite of nature and became an activity within nature, like hiking or biking.Then one day, sometime in the fourth straight hour of pushing a mower around my lawn, it struck me. America’s energy crisis is not simply about the price of gas, or whether coal can be mined and burned cleanly, it is a crisis of our personal energy and how we spend it. Our lives are cluttered with time saving gadgets. We mount our lawnmowers and then, expending nearly no personal energy, blast through our yards. Why? So that we have the time to go to a gym and sit under fluorescent lights watching T.V. while riding a bike that doesn’t go anywhere?It’s hard for me to understand how anyone with an average-sized backyard would use anything besides a reel mower. How did these little, practical machines get replaced by the hassle of the internal combustion engine? Maybe mowing is just another aspect of our suburban automobile culture. Gasoline gives you the upper hand on nature. It allows you to do things your way, on your schedule in the shortest amount of time. We clutter our life with technology that is supposed to save us time and effort, but how do we use the time and effort we save and at what expense to others and our environment is our leisure purchased?I finished the lawn, quickly tucked my mower back in the garage and stepped back for a moment to admire my work. I expected to feel a rush of self-righteous satisfaction knowing that another week had passed without a drop of oil going into my lawn. But instead all I could see were the rest of the places in my life where my energy was being wasted, the places where my convenience was coming at the expense of others. Sometimes by taking a step in the right direction you can see more clearly how far you are from where you want to be. For me the real challenge lies ahead. Maybe the best place I could have started was in my own back yard.Sidebar – Reel Mower Tips and Tricks1. Keep your reel mower sharp and adjusted. A sharp properly adjusted mower requires less effort and cuts the grass cleaner. Most new mowers come with instructions and tools on how to do this. If not, find a shop that can do it for you.2. Don’t let the grass get too high. Reel mowers do not cut effectively once the grass gets higher than the reel.3. Pick up branches and other yard debris. Twigs, nuts, fruit and seeds will jam the reel.4. If you have a large yard, divide it into parts and mow it over the course of several days.5. Buy used – A brand new reel mower will cost you somewhere in the neighborhood of $100 to $300, comparable to slightly cheaper than their gasoline powered equivalents. Used reel mowers can often be found at garage sales or on Craigslist for less than $50.
In a personal video project from Australian filmmaker and biker Raechel Harding, two minorities in the biking community get the chance to share a new story. Female fixed-gear riders take charge in this view of Melbourne from behind the handlebars. Harding, an internationally known and award-winning videographer, created this short film in order to “highlight these talented women, giving voice to women on the scene”. Thanks to Raechel, we can all learn more about the nuances of bike culture from those that come from outside the norm. Check out “Fixed on Fixed” by Raechel Harding, and get a new perspective on these old tricks.Fixed On Fixed from Raechel Harding on Vimeo.
Do you ever sit at work and think, “wouldn’t it be cool to be drinking beer on the river?” I have learned not to leave such important things to fate, which is why we’ve kicked off a new Riverkeeper beer series for this summer. Each month the French Broad Riverkeeper and MountainTrue are partnering with a brewery and outdoor gear manufacturer to create a beer, hold a river cleanup, and paddle all the way down the French Broad River, one section at a time.In May we helped Oskar Blues brew a session pale ale called “Riverkeep it Real”, (aka we poured and stirred some stuff while drinking beer.) The backup name was “Riverkeep Like It’s 1999”. Pretty solid either way. We also drank this tasty beer while lounging in ENO hammocks at the brewery.June’s beer collaboration was extra-easy because Catawba Brewing Co. and Astral were our partners, and as it turns out they had already created a very tasty beer, the Bootie Beer. So if it ain’t broke don’t fix it. Everyone did a great job of drinking lots of Bootie Beer in June, which means we get to keep the lights on and keep cleaning up the river.July’s saison brew with Blue Ghost Brewing Co. in Fletcher will be released this Saturday. We will start the day hauling tires out of Cane Creek and our reward for this dirty work, will be the first taste of our latest collaboration, with a really cool up and coming brewery. Blue Ghost is a new brewery, but the folks there are turning out great beers. (At least they tasted great at 9:30am on the Monday morning I was drinking their beer.)So if you can’t figure out a way to sucker your boss into letting you paddle and drink beer, then come join us and pretend.For more information or to register for any upcoming events go to http://mountaintrue.org/riverkeeper-beer-series/
By Dialogo August 17, 2010 I lived in Barbados in 1952 and I now witness with admiration the level of technology which Barbados has reached, I hope they keep growing because they are a hard-working people. Sailors and Marines deployed aboard High Speed Vessel (HSV) Swift 2 began subject matter expert (SME) exchanges in Bridgetown, Barbados. Swift’s crew is scheduled to conduct SME exchanges in Barbados for the next two weeks, and will continue the deployment throughout the region until early this fall. The exchanges support Southern Partnership Station (SPS) 2010’s primary mission of information sharing with navies, coast guards, and civilian services in the U.S. Southern Command’s Area of Responsibility throughout the Caribbean and Central America. “These professional exchanges between the U.S. and Barbados are what SPS 2010 is all about,” said Capt. Kurt Hedberg, mission commander, SPS 2010. “Over the upcoming weeks we will forge a valuable partnership with defense forces in Barbados, which we hope will result in long-lasting maritime security for both nations in the future.” “It’s always great to get together with another nation’s military and show them what we know, but it’s also exciting to learn about their way of doing the same job,” said Hedberg. “While we hope we have a lot to offer with our knowledgeable facilitators, we know we’re also going to learn a lot from the experts here in Barbados.” While each exchange includes some lecture and group discussion, much of the time is spent in hands-on exhibitions of one another’s knowledge and expertise on a particular topic. Scheduled SME exchanges for the upcoming weeks include small boat maintenance, port and physical security, visit, board, search and seizure (VBSS) operations, and tactical land navigation and martial arts facilitated by the embarked Marine Corps detachment.
By Dialogo January 24, 2011 Ecuador will send 36 tons of humanitarian aid to the victims of mudslides that killed at least 800 people in Brazil, the Foreign Ministry said. Bottled water, food, hygiene and cleaning kits are among the items that will be shipped, the ministry declared. Heavy rains in the second week of January sent torrents of water and mud sliding through towns and villages in a mountainous area just north of Rio de Janeiro, killing hundreds. At least, another 200 people are still missing and 14,000 remain homeless, according to Rio’s state health and civil defense service. The disaster is considered the worst natural catastrophe in Brazil’s history.
By Dialogo December 02, 2011 A Mexican national in charge of a human smuggling ring responsible for the drowning deaths of nine illegal immigrants was sentenced to 30 years in a US prison, prosecutors said. Joel Cardenas-Meneses, 43, was in charge of recruiting illegal immigrants from Central America, arranging their transportation to northern Mexico and then smuggling them across the Rio Grande River to Texas. US officials began investigating the ring after discovering the bodies of seven men and two women who had drowned inside a vehicle that had fallen into an irrigation canal near Hildago, Texas. They determined that the vehicle’s teenaged driver had been driving — as instructed — with the lights off to avoid detection and lost control after making a sharp turn. The victims were illegal immigrants from El Salvador and Honduras. Cardenas-Meneses was arrested in Houston, Texas in February — more than four years after he was indicted on human trafficking charges — and convicted in September.
By Dialogo November 30, 2012 Military Forces representatives at the third edition of the Carlos Lleras Restrepo Paranational Sport Games, which started on November 24, are showing the courage that identifies national Soldiers. So far, six gold, four silver and four bronze medals have been obtained by the athletes during the competition’s first three days, excelling in cycling, swimming, track and field, and shooting. The party reflects the sport’s ideal of inclusion with the arrival of 1,419 athletes representing 19 political administrative regions in Colombia, which are competing in 16 sports until December 2. Around 300 cyclists in the different disciplines for the Paracycling tournament already competed in Cali about two weeks ago, where athletes from Bogotá dominated the competition winning nine gold, four silver, and four bronze medals, to leave the capital as leaders in the medal grid of the III Paranational Games. Major expectations are placed on Corporal Fabio Torres, weight lifting national champion, who is expected to break his own mark again, and Soldier Mauricio Vega, national and international champion in wheelchair tennis, who gave an impressive performance in South Africa 2010. This version of the Paranational Games features 17 sports, 32 competitions, 639 gold medals, 639 silver medals, and 741 bronze medals.
