Utilizing wind power and solar energy or the power coming from the sun’s rays has many benefits. Let us take a closer look on each of them.
•Solar energy saves money.
In 2006, we saw the highest jump on residential electric rate. In some areas of the country, as much as a 60% increase was seen. Some cities in the state of Florida experienced an increase just this month (Jan-09) to start out the new year with. Many experts agree that the trend will likely continue in the years to come. This means that you have to pay larger sums of cash to sustain your monthly electric consumption. However by producing your own power, with the use of eitherwind power, solar energy or both you can prevent paying the high cost of energy – especially now when energy prices Keep fluctuating. Should American households switch to other types of alternative energy the nation’s spending on imported oil will diminish greatly.
From learning to collaborative e-learning….. ……my experiences of being an e-teacher. Suryaveer Singh PGT (Post Graduate Teacher) Geography S.D.PUBLIC SCHOOL, BU BLOCK, PITAMPURA, DELHI , India- 110088
I am a Teacher I am a counselor and psychologist to a problem-filled child, I am a police officer that controls a child gone wild, I am a travel agent, who takes a child to distant unseen places, I am a confidante that wipes a crying child’s tear, I am a banker, who collects thoughts of a child, I am a librarian showing adventures that a storybook brings, I am a custodian of child’s faith, I am a photographer seeing a child grow, When mother and father are gone for the day, I become both, I am a politician that must do tricks I am a news reporter updating on our nation’s current events, I am a detective solving small mysteries and ending all suspense, I am a clown and comedian that make the children laugh, I am a preacher when a child strays from values, I am proud to be these people because…. “I’m a teacher”

More than three-and-a-half years after announcing ambitious plans in October 2007 to become carbon neutral by investing in wind energy projects in India, internet search giant Yahoo Inc is yet to open its account here for such projects.
“The short answer is there is no current activity,” Christina Page, Yahoo’s director for climate and energy strategy, wrote in a response to DNA’s query requesting details of Yahoo’s wind energy investments in India. Page did not elaborate on why there is no current activity.
Why can’t we generate all the electricity we need from the wind? That’s a question that I often hear coming from people who are starting to learn about the environmental challenges that are facing us, and it’s a good question. At first glance, it might seem straightforward: We’re already producing clean electricity using wind turbines, so we know it works. Why not just build lots and lots of them until we produce enough power, thus solving the problems caused by dirty power plants?
Sadly, as is often the case, reality is a bit more complex than that. To answer this question, we need to better understand how wind power works, and how a power grid works. Let’s dive right in, shall we?
How Does Wind Power Work? The gases that make up the Earth’s atmosphere are moving around, mostly because of solar energy. This can create strong winds, and with a wind turbine, it is possible to convert that movement into electricity. Basically, the wind is moving the blades of the turbine, making it spin. In turn, this mechanical energy is making an electrical generator spin, producing electrical current. This generator works on the same principle as the alternator in your car, turning movement into electricity.

If you’ve read my posts and published articles you’ve gleaned some understanding of the noise pollution created near the large, three-blade industrial wind turbines being proliferated across the formerly beautiful and quiet lands of Maine.
Some visiting my site appear incensed at my cautions about this technology, insisting we must do something to reduce pollution from other power generation technologies such as coal, and touting wind technology as a pollution-free alternative.
Now, I already know that wind technology is not pollution-free. It produces noise pollution, a world-around formally recognized and serious health impact, within a locale around each turbine of perhaps a mile, and that locale increases in size for multiple-turbine facilities especially near water or in hill-valley topography. Yet: did you know that the wind turbines require very large quantities of so-called “rare earth” metals to form the large magnets in the generators? That these metals are mined? That these mines are a total ecological disaster, directly affecting the health of thousands of people living nearby?
Wind energy is an inexpensive source of electricity that is being adopted by many westernized countries. Wind farms can be placed in open water and generate enough power to run an entire city. Despite the huge support for this renewable energy source, wind energy pros and cons need to be assessed before jumping into the wind.
Wind Energy Pros
The world’s largest producer of wind turbines, and the whole idea of large-scale wind energy itself, suffered a setback this summer with news that all the turbines at Denmark’s Horns Rev (Reef)–the biggest offshore wind farm built to date–would be moved to shore for repair and replacement of defective transformers and generators. Vestas Wind System A/S in Ringkøbing blamed harsh sea conditions for the substandard performance of equipment supplied by ABB Ltd., the Swedish-Swiss energy conglomerate headquartered in Zurich. The generator and transformer problems made it necessary to retrofit all 81 of the 2-megawatt turbines, at considerable expense.
Vestas, the world’s leading wind technology supplier, installed the Horns Rev turbines in 2002, under contract with Denmark’s biggest power producer, Elsam A/S in Fredericia [see photo, " Let It Blow"]. The mishap at Horns Rev is especially embarrassing because similar problems arose at the first big wind farm Vestas installed, near Copenhagen. The company had expressed confidence when erecting the Horns Rev turbines that this time things would go more smoothly.
Yet to judge from IEEE Spectrum’s reporting and observations in Denmark during late August and early September, Denmark’s commitment to wind, which now supplies about 20 percent of its electricity, is unshaken. Its wind program is a point of national pride, and the manufacture of wind turbines, in this country of some 6 million people, now has a weight comparable to that of auto industries in much larger countries.
With the aim of expediting development of offshore wind farms, the federal government yesterday designated 417 miles of coastal waters in New Jersey as Wind Energy Areas, a move that should tighten the timeframe for approval of projects.
