Find Out How Wind Power Works
Posted by admin in environment on 10 11th, 2009Did you know that you can generate electricity from the wind? This is a rather informative article on how it is possible to provide power to your home utilising wind energy.
My interest will revolve around the following subjects: installing your own solar power system, producing electricity from solar cells or rather a review on how to generate your own power at home.
You have heard that it is possible to produce electricity utilising the wind and you are asking your self; how exactly does wind power work. It’s a good idea to want to know how something functions before deciding to purchase it. This information is all provided in the paragraphs that follow.
Electricity from wind is generated using a scientific principle based on magnetism. Ever notice how you can bring the opposite ends of a magnet together. Well if you can have something constantly cutting the force between the poles of a magnet you can create electricity.
So in trying to know how exactly does wind power work I would give the following answer. The larger the magnet and the quicker you can cut the force between the poles the higher the output that you canproduce. That’s why wind turbines come indifferent sizes. The larger ones are able to create more power. The only disadvantage is they will have a higher kick in speed. This is because wind power is is relied on a supplementary source of power.
So the wind power system is normally linked to the national grid; and only after the turbine speed reaches a certain speed will it kick in take over. For as long as the wind remains above that value it will generate power for you. Excess power that you produce can be kept in batteries for later use.
So if you are contemplating this as an option then you must be in an area where the wind attains speeds of above 10miles per hr. This is the spees that will produce electricity efficiently and get a sizeable output from your wind system. These are just some of the things you may need to know about how exactly does wind power work.

Posted by admin in environment on 08 4th, 2009We so often hear about the benefits of buying locally- buy your food locally, buy furniture made by people in your area, etc. The basic idea is that local products need not be transported, reducing their environmental impact. However, the idea that local creation of products is valuable extends past consumer products. In particular, it’s incredibly important for the environment that electricity is produced locally.
One argument that immediately springs to mind is that all power is produced locally. Californians aren’t getting their power from New York. However, this is largely out of necessity. Making power a local endeavor can be taken much further.
For a moment, consider the factors at play in producing power. First, one has to consider the source of the power (i.e. coal, solar, wind, etc.), then where it’s made (in a plant, in your backyard, etc.), then how far it has to travel (NY to CA or from the source to your breaker box). Something many don’t realize is that electricity does not travel well. While our technologies for creating power have advanced rapidly, our technologies for transporting and storing power have not. Some new developments, such as hydrogen fuel cells, have promise, but the kinks are not all worked out yet.
It seems clear, then, that truly green power is created close to where it is used. This prevents the degradation of the signal that occurs in power lines, in transformers, etc. However, that is not the only benefit. Producing local power takes advantage of whatever natural form of energy is avaialable- be that solar, wind or hydro.
Today it is easier than ever to build green power at your own home. Systems have been created that can be deployed in any number of environments, urban, rural, or suburban. You don’t even need much land today to make some of your power from natural sources, and there are numerous guides to assist you in the process. Thus, thinking globally and acting locally is a tenet that we should absolutely be applying to our power systems. Even a polluting plant in your own backyard would end up requiring you to use less energy than the same polluting plant 100 miles away- and you could sell extra power to the utility company. Thus, building your own green power is a goal that you can take as an environmental goal, a conservation goal, and even an economic goal. I would strongly encourage everyone to at least consider the possibilty of building green power in your own home.

The Alternative Energy Wind Power
Posted by admin in environment on 07 22nd, 2009With so much talk about environmental damage, dwindling fossil fuels, and sky rocketing oil and energy prices it is now clear that we must look for home made energy resources that will be able to supply our endless needs without the possibility of it being exhausted.
Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government,” the Energy Department’s Craig Stevens says. And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. “We should [only have to] pay you the wholesale rate for … your electricity,” according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy. However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, “It’s quality power that strengthens the grid.”
Beneath Power Is Wind
The Sun unevenly heats the Earth that differences of heat distribution; the poles receive less than the equators do. Unlike the land, the oceans, seas and rivers do not have covering so it retains more heat than soil. This contrast results in a global atmospheric convection that reaches from the stratosphere and into the earth’s surface. Energy in these wind movements are stored at high altitudes where in the wind can achieve speeds up to 160km/hr. Here after with the effects of friction the wind’s energy is diffused into heat throughout the planet and its atmosphere. This vast amount of sustainable power can provide us unimaginable amounts of energy, far more than we currently consume.
Wind Speed Distribution
Wind varies in strength. The average value of a certain location does not specify the energy of a single wind turbine. The wind speed’s frequency can be assessed in a particular location, they are fitted by a probable distribution function to the particular observed data. Different wind distributions varies from different locations, hourly wind speeds at different locations are being monitored by the Rayleigh model, which basically means a continuous probability distribution which was named after Lord Rayleigh.
Electrical Generation
Using the power of electricity from a wind farm is usually fed through a network of electrical power transmissions. This is done by connecting the individual turbines with a medium voltage power system and a series of communications networks. The electrical current is then increased with a transformer to be able to connect to the high voltage transmitting system. System operators supplies the wind farm owner with a code that indicates requirements to be able to connect to the transmission grid which includes the power factor, the constancy of the frequency and the behavior of the wind turbines when experiencing system faults.
Now that we know that the speed of wind is not constant, a farm’s energy production is not as much as the sum of the nameplate rating being multiplied by the year’s total hours being used. The ratio of this productivity in a whole year is called the capacity factor. This is the ratio of productivity in a year to this theoretical maximum.
A greener planet using DIY wind generators
Posted by admin in environment on 07 18th, 2009Being environmentally friendly and building a DIY solar panel will enble you to think more about our planet. Cust electricty charges and have the government pay you when you utilize natural wind power. Two keys to effectively using wind power are wind velocity and consistency and if you are located in an area with these key elements the DIY wind generator may be for you.
Position your wind generator turbine in the direction where there is 9 mile or more an hour wind speed. Additionally, the tower used should be made of sturdy wood or steel and away from the home. The height of the tower, the pitch angle and number of blades will all be determined by your individual needs.
Surf the web as there are many sites which offer information and special offers to help you build your wind generator or maybe a solar power system, they will let you know exactly what materials are required. The cost of the overall installation is generally low and a unit will often pay for itself in savings in just a short time.
To avoid damage to your wind generator in strong winds and storms you may want to consider designing the blades to be collapsed when needed.
Why not do some research into how wind and solar power can save you money and save the planet.
There is so much information available to help you make your decision and get more indepth information about environmentally friendly energy solutions. Why not think about harnessing the power of the sun and set up a solar power system. Home which are built with the environment in mind are the future. Take a stand now for a greener planet, whether it is installing alternative green energy systems or recycling. There are many environmental options and ideas which can help keep our planet around.
Go Green Today, don’t forget to be environmentally friendly.
What can you do to be more environmentally friendly?
Posted by admin in environment on 07 16th, 2009Going Green has become so much more popular all over the world. Homes are traditionally known as energy cows. This drain on energy reserves can also be a drain on homeowner’s wallets. Being green can help save money and the planet.
Insulation
Insulation is included as a part of almost every new home built today. If your home is older than this may be different. Building which were build before the 1940’s usually are not properly insulated. Homeowners who’s house is alot older would need to check if it is insulated. Cavity wall insulation is the most common insulation process. Most home insulations can easily be set up in the cavity between two outside walls.
Insulation will stop the conduction of heat into or out of your home and save the power you have traditionally used to heat or cool your home. Sometimes heat insulation in countries such as Japan, America, and the UK is funded by local power companies, so homeowners are urged to contact their power provider before installing insulation.
Turning Out the Lights
Another simple way to save the environment and homeowners’ money is buy turning out the lights. For many years it is clear that when you turn off the lights when you leave a room it will save you money on your bills. But how many homeowners follow this advice?
There are surveys carried out which show that a majority of people do not turn off the lights when the rooms is empty. This is very sad because something as simple as turning out a lights will not only save the environment but will also save money. Most families do not use the majority of rooms in their homes. If they could turn out the lights in these rooms they could cut their power bills by 25 percent.
Of course, you cannot live in the dark and you must have your lights on sometime. Companies have recognized this need to balance the use of electricity and the need to preserve the environment and are now producing environmentally friendly light bulbs. These bulbs use a smaller percentage of electricity every time they are on in the home. They also last longer therefore producing less waste.
Don’t forget to Flush
Water bills rank right up there with power bills when it comes to both homeowners’ expenses and protecting the environment. Water is wasted every day in bathrooms and toilets. Anyone can save water if they really wanted to, maybe turn the water off when you are washing up or turn off the water when you are brushing your teeth. There are products available to install which can help with saving water.
Several companies are making low flow shower heads that reduce the amount to water that comes from the shower every time it is turned on. These types of shower heads are cheaper and can be installed by most people.
Toilets also waste water and devices can be purchased and installed that lower the flow and fill level in all toilets. The devices on the market will allow you to save water when using the toilet and bathroom.
Generate your own electricity using the sun and the wind, this in turn will help you to become more friendly to the planet and your finances. Maybe take a look at building your own solar power or wind generators.
Going green not only helps the planet it also helps you keep a healthy mind and body! Why not try Human Growth Hormone genf20 hgh. HGH is produced during your entire life span from inside your body, it is produced from your pituitary gland, which is the main nerve centre.
Use The Wind To Solve Your Water Problem
Posted by admin in environment on 07 1st, 2009
Water pumping windmills are a very effective tool for the farmers. Farmers often face times of drought where there is just not enough rain, and this is a big risk for losing all the crops and the source of income for the year. However, even when there’s no rain, farmers can use water pumping windmills to save their harvest, provided there is air, which there usually is, because the trees and brushes that block the current of air die or lose their leaves in times of drought.
A windmill is not only a great source of electricity, its a good way to pump water from the ground to water crops. The wind moving the large blades is able to pull water from deep underground. Due to the fact that there is no cap on the wind available, it is a great energy source that can always be used. That’s the reason why you see many water pumping windmills around agricultural centers. Many farmers like the option of free energy to pump water in cases of drought or a big delay in the rainy season starting.
A water pumping windmill is very good for those farms located in areas with abundant wind. They generate plenty of electricity to meet the needs of your family and your household. They can easily be connected to electric fences and provide the power to run them at no cost. This will give animals a small shock if they come tot he crops, but this will only scare it away and not harm the animal. This will keep animals from invading the crops and eating them. It can also be used to keep cattle from escaping. In addition, if an area is flooded, they can be used to pump out the water, in order to dry it.
Water pumping windmills are also excellent to pull water out of the ground and then push it into water storage tanks. Due to climate changes occurring, many populated areas are already experiencing lower water levels and water rationing. If a family always keeps several water tanks full of water for emergencies, they won’t suffer as much the next time public water is cut off, or the pressure is so low that the water can’t reach the top of the house.
So, as you can see, there are many advantages to water pumping windmills. While water pumping windmills are unpractical in big cities, if you live in a farm or in an open area with lots of winds, water pumping windmills are a great idea. In addition, you can’t help but relax when you sit out in your porch and watch those water pumping windmills’ blades rotate with the air.
Solar power and wind power could be the making of you and our planet
Posted by admin in environment on 06 23rd, 2009In the world today the sun has become a more popular energy source and is the most environmentally friendly popular power source for homes around the world. The cost of rising energy bills and the decline in the environment have made people sit up and start thinking of alternative ways of saving money and the environment.
One of the most popular ways of harnessing the suns energy is to turn your home into a solar powered home. The sun can be used to run home appliances, for example: washing machines, driers, cookers, televisions, radios and much more. Solar energy can be used to heat the water you bath in or wash up in.
By installing solar panel heaters you can save money after time and this could also mean the electric companies may end up paying you? The energy you do not use can be sent to the local grid and the provider will pay you.
Solar and wind powered electricity homes are being built all around the world to reiterate to governments that solar homes are extremely efficient and make complete sense. There are also grants which are offered to individuals and companies by the government to assist with the cost of building a solar environment.
If you are confident enough you can build your own solar panels otherwise there are a number of solar companies which will install solar panels into your home for you.
Solar water heating, solar electricity are efficient and a financial plus for everyone. Solar houses, solar flats, solar homes are the future.
There are numerous guides on setting up a solar environment within your home. These guides show you exactly how to build or buy the necessary components to start harnessing the solar energy.
There are many uses for solar power for example: Solar electricity, solar water heaters and solar gadgets (Solar batteries, torches, clocks) Using solar PV is becoming so much more popular and governments are now starting to recognise this. Many governments around the world today offer grants to help you start using solar energy.
Information about solar power is available to everyone and we should embrace it now before it is too late.
Green Energy Source Wind Power
Posted by admin in environment on 05 11th, 2009Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs—while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.
Electric bills and fuel bills are rising steadily—but the cost of wind is is zero, and the cost of installing and hooking up a wind generator kits is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient. In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to “go primitive”, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment. Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers. In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total “green” energy systems’ costs. In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called “net metering laws”. The rates that they are being paid by the local power companies for this energy are standard retail rates—in other words, the homeowners are actually profiting from their own energy production.
Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government,” the Energy Department’s Craig Stevens says. And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. “We should [only have to] pay you the wholesale rate for … your electricity,” according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy. However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, “It’s quality power that strengthens the grid.”
Home Power - Living Off The Grid
Posted by admin in environment on 05 3rd, 2009
When you imagine using alternative energy and living off the grid, do you think you will have to give up your TV or freezer to live that way?Think you have to live like hippies, survivalists, or anti-techno Luddites and live with less technology? Not so. Living off the grid with home power is a possibility open to you or anyone.If you need high-power, for freezers, TV and such, you build a bigger system to drive them.It is not to say.
Because of increased demand driven by the cost of gas and the economy, demand for renewable energy technology has soared, leading to more efficient and easy to use components. Thus, anyone caring about their carbon footprint and eneergy consumption has an option of living off the grid.
Using home power to produce electricity is fairly simple.You need power. Sun, wind and water are the big three right now for home power.Find the one(s) that work for you and choose components to fit.A low voltage direct current is harnessed through the components.Through an inverter, current is converted from DC into usable house current (AC).Your excess current generated can be stored in battery banks and retrieved when needed.
When living off the grid with renewable power resources, there is little special attention needed and is almost completely automated. You do need to:
Tend to the maintenance of your batteries
Monitor your energy use to make sure you keep your supply more than your demand.
The main key to success in living off the grid is making sure you have a system built in a size to meet the demand of your energy needs.
Living off the grid can be exhilarating. The feeling of freedom alternative energy brings is like breathing fresh air. You can be proud of yourself in helping to combat global warming.Just think - power outages may be a thing of the past.
It is important to research and determine which are the best alternative energy sources for your geographical area, for example, the number of days of sun in your area, or average wind, but it is definitely worthwhile to learn how to live off the grid and feel the rush of freedom being off the grid can give.
Renewable Resources To Power An Energy Devouring Planet
Posted by admin in environment on 12 24th, 2008The world as it is today is an fuel thirsty place and it’s imperative that we be researching greener channels of power to provide that thirst. We also need to discover better ways of utilizing the current sustainable energy technology that are already in place. We all need to be worried about the impact that is being placed on our earth and how the high cost of energy is affecting us. It makes no sense the amount of energy that is wasted each and every day. People should be more sensible of what they could do to be more moderate in their use. It doesn’t make any sense the amount of energy that is wasted each and every day. People really need to be more aware of what they could do to be more moderate in their utilization. There are solutions to these problems but how willing have people been to carry out these solutions at the present.
One of the more popular forms of renewable energy is wind power. The price of the power it develops is turning very competitive with established methods of energy production such as coal and natural gas. Power used to be created by windmills in the past on the family farm for many years. Back in the day farmers were real trend setters because you could find one on every farm and it was used to provide power not as a yard decoration. It is an identified fact today that the states of Texas, Kansas, and North Dakota have adequate wind to supply power for the whole U.S.
Corn over the past several years has been seen as a savior to our oil dependence. The ethanol that is created from corn is a clean burning energy source and crops can be grown year after year so it is inexhaustible but at what cost. The cost of corn has gone up as the result of this, which is good for the farmer but bad for the consumer. There are better alternative to corn and one of them is prairie grass. It actually produces more energy per acre than corn. Prairie grass grows wild. You don’t have to cultivate or tend to it. It is a chemical free crop that just needs to harvested and processed.
Another renewable energy source we see and hear more of is solar power. There are solar panels that will convert the suns energy into electricity and solar water heating systems to provide hot water. I recently read an article in a solar energy magazine about a family that installed a solar energy system on their home. They lived in Seattle. Of all the place in the world to put up a solar installation. Believe or not they had a respectable payback. Even though this is a very cloudy rainy area the ROI was very amazing.
Solar power offers the chance for people to take charge of their own energy independence and self-sufficiency. The control of power can be decentralized. Maybe that is one of the reasons why there hasn’t been as much advancement as there should be and why costs remain high. Large corporations want to protect their profits and unfortunately it almost seems as though they’d do anything to make that happen.
Regardless there are many alternatives that are now being explored because we know we can’t stay dependent on the oil pipeline forever. Aggressive measure need to be taken to start setting in place and implementing a new energy infrastructure. We can start to benefit from it now but we also need to think of how it is going to be of value to the next generation. You can do something to help make green energy a very real possibility for everyone.
You can learn more about solar power, wind power , and other forms of sustainable energy sources by studying on-line about the subject that intrigues. Be green and help keep the globe healthy and vibrant for our children.
