Wind Generator Basics

Moon Rise behind the San Gorgonio Pass Wind FarmWind generators are basically a propeller which is then attached to a generator and produces power. Small wind generators are capable of producing small amounts of power. There are larger wind generators who are capable of powering huge amounts of power, enough to be used commercially.

Wind generators, or wind turbines as they are more accurately described, attach to generators that are connected to the local electric grid. The power produced by the wind generator goes directly into the electric generator and reduces the need for traditional power sources. The amount of power added to the local power grid is variable.

There are many different types of wind generators, in different styles. There are horizontal wind generators, which must be pointed directly into the wind. They generally have gear boxes that are used to increase the speed of the rotor?s rotation, which powers the generator. These are the most commonly used forms of wind generators, and are most commonly in a traditional three spoke design.

Vertical wind generators, on the other hand, have the distinct advantage of not needing direct access to windy places. This means that they can be placed almost anywhere, including on the top of a building. Unfortunately, because it receives less wind, the vertical wind generators produce less power.

If an area has enough open areas with direct access to large amounts of wind, it can utilize wind generators for large amounts of their power needs. This requires such a large amount of windy land that there are very few areas with this kind of set up. As a result, wind generators are not being used to produce the bulk of their power options.

More commonly, wind generators are used to create smaller amounts of energy, which are sufficient to power a single household or business or to help offset the energy usage of a business. For this purpose, there are small wind generators that can be added to businesses or houses.

For areas with large open windy spaces, a wind farm is a good idea. This is a large amount of wind generators, placed in the field in the way you’d place fruit trees, which all plug into generators and eventually, the power grid. This produces large amounts of energy, reducing the area’s dependence on traditional energy sources.

Wind generators are a clean, quiet, alternative energy source. Because of the many advantages offered by wind generators, there are more and more people who are becoming involved in bringing wind generators to their local area. Wind generators have several advantages, but those that are considering them need to be aware of their limitations.

Basics of Generators and Repair

Some services have to operate even during a power outage, so a backup generator critical for hospitals, fire departments, and phone companies. What is essential for these organizations is becoming increasingly popular for individual homeowners because of the convenience and security a backup generator provides. If you are contemplating a generator, it is important to consider your actual power needs, safety precautions you need to take, and the ongoing cost of generator repair and maintenance.

Generators come in all shapes and sizes, from the high-output generators used to power hospitals and other vital services to the small, portable models used for power while camping. The cost of a generator is roughly equivalent to the amount of power it puts out, so in order to get the best value it is important to start by assessing how much power you will actually need.

The best way to start this assessment is to begin by looking at your electrical bill.For most of us, the only part of the bill we pay attention to is the amount due, but the bill also tells us how much energy we use. By tracking that consumption rate over a couple of bill cycles, you can determine how much energy it takes to run your home under normal conditions.

It is also important to bear in mind that the times you will use your backup generator will not be normal times. You may be able to save a considerable amount on the purchase of a generator by taking a look at how you can reduce your normal consumption during a power outage. This may also help you to find ways to conserve energy under normal circumstances as well, saving money and making your household more environmentally friendly.

Safety is a very important concern when selecting and installing a backup generator. Each year, asphyxiation from carbon monoxide claims the lives of homeowners whose generators are not adequately ventilated. Just like a car, a generator’s exhaust can be lethal in high concentrations, so you should have your new generator installed by a professional who will ensure that it is properly ventilated and who will make sure you understand other precautions you should take for safe operation.

In addition to the cost of buying and installing a generator, it is also important to consider the ongoing costs of operating the generator. Most generators are gas powered, but generators are coming onto the market that burn a variety of kinds of fuel. While bio-fuels and other eco-engineered options may seem attractive, the costs of these fuels in the long term needs to be part of the buying decision.

Maintenance and repair are also important to consider. Many new generators come with full warranties and have extended warranties available. If you are buying a used generator, however, it is a good idea to look into generator repair providers in your area and to talk to them about the reliability and value of the model you are considering.

Once you have covered your bases by investigating fuel and generator repair costs, by assessing your electrical needs, and by making sure you know how to run your generator safely, you will be ready to make an informed buying decision. The next time the weather is cold and the power goes out, you’ll be glad you did.

How Wind Generators Produce Power

Windmills at the windmill farm MiddelgrundenWind is everywhere, and it is part of the planet’s most widely available sources of sustainable, renewable energy. It is a growing part of long-term strategies for large-scale power production. Small-scale wind power generators cause minimal environmental damage. And as the wind generator increases in efficiency, wind will likely be responsible for more of the power that we use every day.

Using wind to generate power is simple. A windmill is erected high enough that the propeller at its top is above obstacles. Wind blowing across the propeller turns it, which turns a turbine, which drives a generator. The power output of a good generator is approximately 2,300 kilowatt-hours per year.

Wind turbines are used on a small scale to provide supplemental power, similar to residential solar panel installations. This is especially prevalent on farms and other rural-industrial establishments in flat areas where consistent wind is plentiful. Much larger installations of wind turbines, called wind farms, are also becoming popular.

The largest onshore wind farm in the world boasts 627 turbines, generating enough power for 250,000 households. It was built between 2008 and 2009, with a total construction cost of over $1 billion, on a site near Roscoe, TX.

The largest off-shore wind farm in the world almost wasn’t finished. It was beset by financial challenges during its development, and the project changed hands numerous times. However, it was finally built and it now lies 7 miles off the coast of Thanet district in Kent, England. It covers approximately 13.5 square miles, cost about $1.4 billion, and adds 300 MW of power to the Kent grid.

There is plenty of criticism of wind power, especially the large-scale projects that cover vast areas of land or sea. Of these, the most common has to do with the unpredictability of wind. A windmill is expensive to build, and in order to be cost-effective it needs a high average wind velocity. However, winds change from day to day and from year to year. It is difficult to ensure that the infrastructure investment will pay off. And in fact, without subsidies wind production is rarely cost-effective.

Wind power is also ironically criticized for causing environmental damage. Although the production process doesn’t use any fossil fuels, large scale wind farms do take up an enormous amount of space. The areas that make good wind farms – rural zones with high average wind velocities -are often home to birds. Construction of the wind farm can upset their habitat, and once it is built the spinning blades can kill them. One company’s recent application to kill golden eagles in order to build a massive wind farm has drawn strong criticism from animal rights activists.

However, a high quality wind generator in the right location does hold the promise of producing energy for a long time. As a result, it stands to reason that large-scale wind farms will continue to proliferate and that those who care about the environment – or about their own independence from the energy grid – will continue to look at wind as a source of private energy production as well.

The Benefits Of A Propane Generator

Navy supplies generator to Aceh hospital after tsunamiRegardless if you use it for portable, recreational, business, or residential reasons, a propane powered generator is a great way to power a generator. Propane barbeque grills are used by many outdoor cooks. Propane is a nonrenewable fuel that is made from both crude oil refining and natural gas processing and is frequently called liquefied petroleum gas and will burn much cleaner than any other fossil fuel. The propane fuel is stored in safe cylinders that are easy to connect to appliances and refill. Propane generators are very easy to fill and use in the same manner.

Unlike gasoline that has a limited shelf life, filled propane cylinders can be easily bought and stored. While propane will produce carbon dioxide, propane generators are safer for the environment, easily moved, and uncomplicated to fuel. Propane generators provide a very efficient energy output to cost ratio, can fuel large fuel cylinders, and can generate sufficient electricity to run many different devices for a long time. Propane generators can meet the electrical requirements of several electrical applications in this way and provide a considerable amount of power reasonably.

If you live in a region where the electricity goes out frequently, a propane generator can be lifesaver. The propane and gasoline powered generators are the most popular. There are many benefits to propane generators. It is difficult to justify purchasing any other kind of generator, because there are so many benefits that propane generators have over any other kind.

You can find Propane tanks located in department stores, camping stores, and home repair shops. Sometimes even gas stations will sell propane tanks. However, gasoline can only be purchased at a gas station. If you should find yourself in some kind of natural disaster or even a snowstorm that causes your electricity to go out, the gas pumps in gas stations won’t do you any good. You are simply out of luck if you are out of gas. In addition, propane generators don’t need to be refueled and will run for longer than any other kind of generator.

Because owners don’t have to handle the filling and refueling, there are fewer opportunities for fire hazards with a propane generator. All you have to do when your propane generator is out of fuel is purchase a new tank of propane and reconnect to your generator whereas with a gasoline generator you have to refuel it yourself. Propane also has a longer shelf life than gasoline because it doesn’t evaporate like gasoline.

You will save money by using a propane generator because propane is more efficient and less expensive than gasoline. Also, a generator that is powered by gasoline will have a shorter lifespan and will break down more frequently. Propane generators will also save you money on replacement and repairs because they experience less wear and tear even when they are run frequently.

Propane generators emit less harmful fumes and are cleaner to operate. The generators that are powered by gasoline can contaminate or stain the surfaces that are surrounding them and will produce more odors. Conversely, propane will dissipate while the generator is running because it is simply a gas.

The Answer, My Friend, is Blowing in Wind Generators

I love a sunburnt countryYou’ve put a lot of strange but pressing questions into Google’s search box. How to cook mahi mahi tuna in the oven. How to beat the many versions of “Grand Theft Auto”. How to fix your windshield wipers. Will I ever be married to Robert Pattinson? You may not have known how Google would find an answer to that last question, but you typed it in anyway. Now, your question involves wind generators. As in, “What in the world is a wind generator?” The good news is that question can be answered. (Yes, Google saves the day. Doesn’t it always?) Whether you’re writing a report or just have a desire for basic knowledge on wind generators, read on.

What is a Wind Generator?

You might want to be snarky and think “something that generates wind.” While you wouldn’t get the prize for cleverest witticism, you’d be about a quarter of the way there. Wind generators make electrical power from the energy of the wind.

There are two types of wind generators. Wind generators that convert energy for the purpose of operating machinery are called windmills. Wind turbines are those contraptions that get turned into electricity.

Wind Generators: What Do We Need Them For?

The answer is that we need wind generators for a variety of uses. Compact versions of turbines can be used to charge batteries. They can also be used as auxiliary power for boats. In the past, windmills have been used to mill grain and to operate other industrial machinery.

Now’s the time to go from small wind generators to ones on a bigger scale. Large scale electrical systems are often connected through grids consisting of…you guessed it, huge wind turbines. You may see some of these turbine farms in out of the way locations such as locations in Europe and the South Pole.

Fun With Wind Generators

The Enercon E-126, at a height of 650 feet, is the largest capacity wind turbine in existence. In the past few years, several companies are involved in a race to build turbines even larger than the Enercon E-126.

Ancient Greece might have been home to the first ever windmill. Heron of Alexandria created the first windmill prototype well before the start of the Industrial Revolution. The item consisted of an air tight chamber heated by fire, which displaced the water put in the chamber beforehand. After the water is collected, the resulting weight would open doors.

That was just a brief introduction into the wonders of wind generators. Whether you’re discussing turbines or windmills, the many actions that can transpire from the power of wind can be mind-boggling. Because of this technology, not only can you power the batteries to your remote control, but also steer a boat. Remember to thank Google the next time you’re searching for cheat codes to “Call of Duty.”

The Windmill Farmer
A nurturing farmer in is danger of losing his crop of windmills when he struggles against the cyclical forces of nature. Created at the UCLA Animation Workshop, with music by Nick Fevola. This film was inspired while driving back from a trip to Palm Springs, when a friend said that it must take them forever to plant and grow so many windmills. I wrote down the title The Windmill Farmer for an idea to explore later, and about a year later I started developing it into a character and story. This film took 4 months to complete from the first boards until the final mix. Watch more films by Joaquin Baldwin: www.pixelnitrate.com Follow Joaquin Baldwin on Twitter twitter.com
