Advantages & Disadvantages of Wind Energy – Things You Should Know About

Wednesday, August 31st, 2011

The Pros

Wind energy (WE) has been developed in the past several years so that it is now cost competitive to other fuel sources (like natural gas) and it is the least expensive of all renewable energy sources. Because the fuel in the form of blowing wind is free, wind energy can provide a stable long-term cost for energy production. So is it surprising that wind energy is the fastest developing energy generation industry around the world?

We can help to meet the growing global energy demand, and commitments from governments globally to international agreements including the Kyoto Protocol (UNFCCC 1997) to eliminate the emission of greenhouse gases, as well as individual country commitments to mandatory renewable power goals.

Due to the right support it has been claimed that it can provide up to 28% of EU electricity by 2030. WE is also advantageous over conventional methods of creating energy, in the sense that it is getting cheaper and cheaper to produce this kind of energy as the technology develops, and mass production of the blades becomes routine. Wind may soon be the cheapest technique to produce energy on the large scale, after all, it has come so far already in such a short time, and there should be a lot more methods to optimize its efficiency not even dreamt of yet.

Wind energy is very abundant in many parts of America. Blowing wind sources tend to be characterized by wind-power density classes , ranging from class 1 (the lowest) to class 7 (the highest). It is clean energy. Unlike coal or natural gas, every kilowatt-hour of this kind of energy is free of charge of toxic emissions that contaminate our atmosphere and water.

In contrast to coal or natural gas, every kilowatt-hour is free of toxic emissions that contaminate our air and water. Wind farms create no atmosphere or water pollution because no fuel is burned. It is in reality just a form of solar energy.

Using windmills is an extremely ancient ability, which may have even been developed in China before 1 AD, but the earliest written documentation comes from 1219. Cretans were reported to be using literally hundreds of sail-rotor windmills to pump water for crops and livestock. WE does not sterilize land from production. Farmers and ranchers can continue to work the land because the generators use only tiny a fraction of the land area.

Wind energy plant owners make rent payments to the farmer or rancher for the use of the land, which supports the economy remote areas and provides job opportunities for local people. Farmers who own land that is ideal for wind farming could also take advantage of their location simply by installing their own wind generator or by renting wind rights to a wind energy company.

Then methods we use today to harness the blowing wind are still developing. This is not a great technology, but it holds powerful potential to diversify energy generation all over the world.

The Cons

Wind energy is not easily stored, and not all air currents can be harnessed to meet the timing of electricity demands. Good wind sites tend to be located in remote locations far from areas of electric power demand such as urban centers. This means that huge investment will be required in brand new energy distributions systems that will add to the cost greatly, and mean a lot more unsightly energy lines marching across the land.

So, wind energy is not necessarily the cure all it is offered to be. Due to the intermittent nature, industrial scale WE can produce about 10-21 % of the set up capacity (wind advocates claim 30%), requiring back up generation of 80-90%, which is usually going to have to be natural gas or coal.

Wind energy is not a linear function of the speed of the blowing wind. For instance, an increase in wind speed from 5 m/s to 6 m/s leads to an increase in the yield of a turbine of not 20% but usually of 45%! But, once the wind rises too much no power at all is generated as the wind generator blades are furled for their own protection.

However, this particular energy source method could be built on the small scale easily. Models can be found which range from small size residential wind turbines creating about 10 kilowatt of energy to experimental behemoths that are over 500 feet tall and produce 3 MW of energy, wind harnessing technology has many forms and purposes.

Terribly positioned wind energy facilities have the potential to create major problems for wildlife, especially for bird life. Turbines mounted on buildings which were not designed as a turbine foundation commonly shake apart over time. Additionally, the vibrations produce sound and may be unbearably noisy for those in the residences nearby. These are the major advantages and disadvantages of wind energy.

Electric Underfloor Heating Or Water Underfloor heating

Saturday, August 27th, 2011

Underfloor heating is one of the very best methods of keeping the home warm and comfortable. In truth, it’s quite an energy saver too. The amount of energy required to heat your home with underfloor heating is about 15 percent less. If you want to save money and energy, don’t simply consider the obvious such as solar panels. Underfloor heating doesn’t waste energy by heating the ceiling, it offers a cozy warm floor to rest your feet in the morning and keeps the room you occupy warm.

In traditional heating, the warm air blows into the area. Basic research tells us warm air rises, so while our top halves are toasty warm, our toes are experiencing the winter chills. With underfloor heating, the process is the same, other than, the warmth begins at the ft. Instead of dry air blowing onto the area and rising, the floors warm and radiate the heat. Doing so eliminates the need for a radiator that wastes space. It also means it is possible to set your thermostat lower since you’ll benefit from the heat rather than waste it warming the chandelier.On top of the energy benefits, there are air high quality benefits too. This type of heating doesn’t reuse the dust and dirt or stir it up.

In fact, a lot of experts consider this method of heating as the very best to reduce the potential of allergens in the home. Since mites and molds are often the cause of many allergies, the heat that stems from the flooring reduces the relative humidity at the floor level where they often live. Several studies show the decrease in mites and mold with this form of heating.

Once you decide to choose underfloor heating, you’ll have another selection, the type of heating to select. There are several types from which to select. One is the electric or cable type of underfloor heating. It contains strands of copper with a protective conductive jacket. The wire warms in the covering and the area above it. Because it’s waterproof, it’s the ideal solution for wet areas such as bathrooms. To accomplish the task of heating, you can use a cable heating matt for quicker installation in large areas or basically use cables if the region is smaller or more complex.

Within the world of electric underfloor heating, there are various types of heating products. Each one performs best in certain circumstances. For instance, the type of floor covering you have makes a difference in the set up of the product and the type of product you use. If you’re fitting an electric underfloor heat in a wet area, such as a bathroom, choosin one designed for a wet area is necessary. The amount of insulation and type of insulation you use also varies.

With the water-heated version of the product, the heating system is a series of pipes in the floor. This type of heating generally works best in new construction since the piping goes into the cement screeded subfloor. One huge benefit of water underfloor heating is the ability to use it to cool, something the cable heating can’t provide. Just as the warmed water heats the floor, cold water run through the pipes reduces the heat.

Irrespective of the type of underfloor heating you select, you’ll find it another way besides solar panels, to keep the cost of your energy use lower. Depending on the type, saving money doesn’t occur just in the winter months but also in the summer by deflecting the warmth.

Underfloor heating is becoming something that a lot of house owners are thinking about; however, there are some key choices to make. You will need to decide where in your home you want the underfloor heating and what style may suit your needs best. Although both styles are equally good, some people prefer to have electric underfloor heating and others like the water underfloor heating.

The water underfloor heating works by a system of water becoming heated and circulated throughout the pipe work under the flooring. This system will use the water from the radiators and can circulate it evenly throughout the whole area. The pipe work that is installed is quite long lasting and will last on average up to 100 years.

Though this style of underfloor heating is more expensive, it will cut your energy expenses significantly. Having said that, it can be plenty of work to have the pipe work lay correctly, and this can take longer and cost more than the alternatives. The electric underfloor heating is a good way to provide uniform warmth throughout the area, and supplies the heat through mats and cables.

This system of underfloor heating is far easier to install, which lessens the total cost of the process. The electric underfloor heating requires very little maintenance and there is very little that can go wrong. You have the ability to use numerous thermostats to control the temperature throughout the home.

However, with the water underfloor heating you will need pumps and valves to control the temperature. Although both systems have their good and bad points, whatever underfloor heating you decide on it will heat your home very well. Not only will the underfloor heating provide you will a great warm home but also save you cash.

With increasing gas costs, individuals are wanting to save money in any way that they can, and solar panels, underfloor heating and insulation are all common options. You need to take into account what style of underfloor heating is best for your needs and budget.

the style that is selected will be determined on the style of floor that you have throughout your home. New builds are excellent for water underfloor heating, due to the construction and ability to conceal the pipe work. Older style flooring will need to be lifted and raised, which may be a problem, and this is frequently why electric underfloor heating is selected. Both systems are good and something that all home owners should take into account.

Both systems will provide an adequate heat supply for your home and make sure that no other heat source is needed. The running charges for both systems are very energy efficient; however, it may cost slightly more to run the electric underfloor heating. You will need to take into account if you want greater installing costs and smaller energy bills, or a smaller start up cost and greater bills. Both of the styles of underfloor heating have their benefits, and you need to decide, which one is suitable for you.

How Might Solar Energy Produce Electrical energy

Tuesday, August 23rd, 2011

The sun creates enormous amounts of energy which are transmitted down to the earth’s surface. As soon as the sun’s light contact the earth’s surface the intensity of the heat directly from the sun is not as hot mainly because some of the heat energy is really rerouted before it actually reaches the earth’s atmosphere. When the sun is hot and it’s summer time we feel that it couldn’t get a lot hotter as the mid day sun makes you run to find shade, but it could get hotter if it wasn’t rerouted.

Solar power could be hot enough to power machinery and that is what precisely ended up being discovered more than one 100 years ago when a man working on machinery wondered if steam from the warmth of the day may well be used to power up machinery. He was correct and therefore created a new form of production, heat and electrical energy. These days solar technology is being used everywhere across the planet. The sunlight power is being concentrated directly into a Solar Panels generator where the heating is utilized in many different ways. We nevertheless depend on our method of heating and powering our homes but in the near future it might all be powered from the sun. It is actually cost effective to make use of solar power as the only costs you have is in your solar power panel.

To use solar powered energy you will have to have some thing which can attract the direct sun light and allow the heating to be targeted where it can stay warm for long periods of time. This really is reasonably easy when you consider all the know-how and also resources of which we already have access to. When you use solar technology for heating and power source of electricity you can not fail.

Solar power is entrusted in space shuttles because they realize that this will help create the most efficient energy with the least amount of difficulties. The solar power panels are faced toward the sunshine at all times to be able to power the shuttle efficiently. There are a lot fewer problems from solar power than with other methods. Even when there tend to be days that there are clouds in the sky in addition to rain, snow or some other weather conditions, it is still possible to develop enough heat in your solar panel to create enough energy to last until the sun can come back down. Solar power is in our foreseeable future we must be prepared for it. Right now solar systems is just being used by those who’re more aware and concerned with regards to our earth’s atmosphere when it’s a concern we really should be concerned with.

We can learn a lot from the past and the way in which solar technology was utilized. Every minute of the sunlight was used doing everything that needed taken care of because after the sun went down there was no longer light. I don’t believe that we could do this at this point. Solar power has so many amazing advantages for us that we don’t recognize them all and just how it can be a whole lot more efficient to use the solar power than different methods.

Build a Windmill To Change Our Energy Dependency

Wednesday, August 17th, 2011

We are in the middle of an energy crisis. Our fuel sources tend to be running low, and we are leaving an permanent mark in our environment. However, there are things that you can do to change your energy dependency. Building a windmill is a fantastic way in reducing your energy costs and to eliminate carbon footprint on earth as alternative renewable energy that is available for free.

Once you have made the decision that you want to commit to constructing a windmill in your home you will need to spend a little time doing some analysis. The first step in constructing a windmill is taking a careful look at learning the quantity and pressure of wind, known as the quantum, that flows through your property. If you have been in your house for a fair period of time you most likely have a good idea, but if not you will want to take some time to document the wind levels in your area.

You second step toward constructing a windmill is to establish a construction plan. You might have to accomplish a little research about this, but it is not a tough plan to develop for those who do not have a technical qualifications. When developing your windmill-building plan you don’t have to buy the top of the line equipment. There are very inexpensive yet powerful pieces of equipment on the market. You can actually get a windmill-building project going for under $200. That is a small amount of money to invest when you think about the money that you will be saving by supplementing your energy from your windmill. In fact, it is really worth noting that by using a windmill as your primary power source you will be able to save around 95% on your energy prices.

When constructing a windmill you will want to buy a DC motor. This might be the most crucial supply for your windmill project, but it is also the highest priced one. You will need to be prepared to spend about $35 on your DC motor, but it will be the heart of your windmill’s operating system so you will be sure to recoup your prices quickly.

According to your individual building plan you will then need to buy the other parts that you have set out on your to buy list. It is a great time to do this while you are waiting for your DC motor to come in.

You will also have to spend some time looking for a recycled body for the windmill project. By finding a recycled one, you will not only be saving yourself money, but you will also be practicing the earth awareness that you were trying to take on with your original project of making a windmill.

Once you have purchased all of the items that you need you can begin production of your windmill. If you get your entire family in on the act then it might only take you about five days to put it together. If you decide to make a wind generator together with your family, it won’t only help to save you money, but it will also help bring your family together!

Crucial Considerations On 3 Ways To Think About Solar Electricity

Tuesday, August 16th, 2011

If you are entertaining the idea of alternative forms of energy generation, you’re almost certainly wondering about solar panels. You’ll find 3 various ways to generate solar electricity this way and every one has certain setup and equipment needs. Let’s look at the various techniques:

For grid inter-tied, we will be completely linked to the local electricity supplier. When you do that the power produced from the solar panels is sent through an inverter and through an AC breaker unit, supplying the household needs but in addition delivering it back via the meter to your utility grid. In some instances your meter will move backwards as you receive credits for the amount of power that you’re generating over and above your usual, home needs.

The next technique we can look at is basically much like the initial except that this one has a battery backup as well. At this point, if a blackout occurs you’ll have the means to retain some of the energy that you created, so that you will be able to function even during darkness. Although this option may not be as efficient in total terms as the previous one, many homeowners appreciate the security they can get by initially paying for any additional components essential to put a battery bank into the line.

Of more value to those people who live in very out of the way areas, an off grid system can nonetheless be the final word with regards to providing for yourself and maintaining self-sufficiency. This might require a certain type of living however and when you’ve been used to the “constantly accessible” power available from the supplier, you will invariably become used to switching things off whenever you don’t need them and using your generated power sparingly, too.

There are quite a few components needed in any system however so if you are not so inclined you may well find it better to talk to professionals in this field, who will be able to handle the design and assembly of systems in accordance with your defined specifications.

Learn Exactly How Wind Power Works For Your Home Alternative Energy

Sunday, August 14th, 2011

One of the greatest types of renewable energy – it is Eco-friendly, clean, and never-ending! In a way, wind energy is the result of solar energy – our planet’s wind starts because of the sun heating our planet’s surface unevenly, causing wind the rise and fall at various rates all over the world, and the air begins to move about based on physical law, creating what we experience as wind. Wind turbines stand in the wind and this causes them to turn, to spin, and to generate energy. And with your own wind generator you can take advantage of this free energy to generate your own electrical energy rather than paying the energy company to get it done for you — and their energy is usually produced from non-renewable, non-environmentally friendly sources.

But before you start to use a wind generator, you might want to know precisely how wind energy works. The most straightforward way is to imagine a fan going backwards in time: instead of electricity interacting with magnets to turn the fan blades and hence generate wind, the wind turns the fan blades and this interacts with magnets to create electricity. Put simply:

* wind blows on the blades of the fan
* the fan blades are angled and hence begin to turn
* the axle holding the blades spins
* the generator at the other end of the axle generates electricity

There is usually a gearing mechanism to amplify the motion, thereby producing even more electricity. There is also usually an automatic stopping mechanism to avoid possible harm to the entire assembly if the wind speeds gets too high. Domestic wind turbines usually come in two varieties: (1) Turbines with a vertical axis (2) Turbines with a horizontal axis It is the second form that is usually favored now, and upon which the US Department of Energy is focusing most of its research recently. These usually have two or three blades (those with two blades usually faces away from the wind, and those with three blades usually face into the wind).

You might have observed huge three-bladed wind turbines around the countryside, clustered together in what are known as wind farms, and they can produce a lot of electricity — the larger the blades, the more electricity, in general. Domestic wind turbines are much smaller, and can create typically 50 kilowatts for home use.

In remote rural locations wind turbines can also be used to pump water out of the ground, and such places will often create electricity utilizing a combination of solar panel systems and wind turbines. They make use of batteries to collect excess electricity they have generated, and in some cases they can even sell additional excess electricity back to the energy company!

However in an urban setting a wind turbine will be used as a supply of energy to supplement the normal grid supply of electricity from the power company. The reason for this is that there is usually the opportunity that there is not enough wind energy to generate electricity — if the wind is much below 8 miles per hour then most wind turbines will not generate energy, and the grid will supply the electricity requirements. As the wind speed increases and the wind generator generates more electricity, the total amount taken from the grid gradually decreases.

A general rule of thumb is that the average wind speed must be about 11 miles per hour; if it is lower than that the tower supporting the generator will have to be higher to trap the higher-speed winds at higher altitudes — but there are diminishing returns there and if your wind speed is often too low then it may not be worth setting up wind turbines.

Taking into consideration not only the cost savings from not using grid electricity, plus the occasional opportunity to sell energy back to the energy company, wind turbines can help to eliminate a home’s power expenses simply by an amount in the region of 50% to 90%, although there are lots of factors affecting this. If your home uses 10,000 kWh (kilowatt-hours) of electricity each year, a small generator of rating between five and fifteen kilowatts should be sufficient to your requirements. There will obviously be initial expenses associated with setting up a wind generator, but these will quickly be recouped — and you will save more money by building one yourself – instruction manuals and videos are available for a low price over the internet.

Now that you’ve got some idea of how wind energy works, you need to think seriously about setting up a wind generator for your home – not only will you be saving money, you will also be saving the earth – and all because of a little breeze!

A Bright Future For Solar Energy: An Alternative Energy Source

Saturday, August 13th, 2011

Sun energy is the cleanest and inexhaustible of all known energy sources. Solar energy is nothing but the light, heat and other radiation that is emitted from the sun. Solar radiation holds giant amounts of energy and is responsible for all the natural processes on earth.

The need of the hour is to build solar power. They can no longer afford to spew out tonnes of carbon dioxide in to the atmosphere, nor can they easily cope with the rising fuel prices anymore. The myth of a never-ending natural reserve has been dispelled. They are surrounded by renewable sources of energy all around us which is fundamentally waiting to be tapped in to.
