Wind Turbines And The Direction Of Renewable Energy

Wind turbines.

 

Wind turbines are one of the safest and cleanest means of generating energy and wind farms are a sustainable solution to our energy crisis.

There is significant growth in the wind turbine industry around the globe and many offshore projects are being planned and implemented now. Wind turbines are popping up all over the world. It is not unusual to find single windmills or acres of wind turbines creating clean energy these days. This energy producing alternative is costly to install, but very effective in reducing the price of energy for consumers over time. This type of natural power is clean energy, but what exactly does that mean? Wind turbines do not rely on fossil fuels or natural gas to produce energy and therefore do not deplete the earth of its natural resources. This power can be directly acquired from the country in which it is generated, cutting importing costs and further reducing prices for the consumer.

 

The Manufacturing Of Windmills.

 

The economic growth of the industry also lies in the manufacture of the windmills themselves. The more in demand they are, the more economic and employment growth will develop. This growth not only depends on building the actual windmills, but also on manufacturing the batteries, capacitors, and cables which store and transmit the energy accumulated by these rotating giants.

 

Offshore Wind Farms.

 

It has been predicted that by the year 2030, many of these wind farms will be set offshore. The huge turbines would almost not be seen above water, but the power they would produce could be immense. This is a first of its kind innovation and is reported to be somewhat stalled in the bureaucratic phase for the time being.Batteries will ensure that the turbines will continue to move even when the force of the wind is significantly reduced. By contrast, the East Coast wind farms will probably never suffer from a lack of power source. These farms will be highly productive and the predicted outlook is excellent for the immediate future and long-term future.Huge offshore cables, called “spines”, are buried in shallow trenches under the sea to transport the collected energy to the mainland. Initial reports indicate that this development could possibly produce enough wind energy to sufficiently power the entire Eastern seaboard. The cable is being laid now, even before the windmills are planted.The amount of energy created by these offshore farms is predicted to significantly reduce the load of the current energy grid in the Northeastern US. The cost of this project is said to be in the high mufti-billion dollar range, which is causing some delay. There are other significant factors, however, which are also delaying the progress of this project.Fishermen make their living off the North American eastern coast and studies are being conducted regarding the reconciliation of the two industries. Another problem being faced is the fact that there are sacred burial grounds submerged in the sea there, which should not be disturbed. A third hindrance is the assumption by special interests groups that this development will destroy the beautiful view off the East Coast, who are lobbying to stop the project.Wind turbines are one of the safest and cleanest means of generating energy, providing economic growth and reducing the load on the current energy grid. Along with solar power and thermal heat, it is a viable and sustainable solution to our energy crisis. There is significant growth in the wind-turbine industry all around the globe. There are many online sites with information regarding the direction in which renewable energy efforts are headed for the immediate and long-range future.

Wind power solutions at home

Wind power solutions

With the world’s ever-increasing demand of power being more than its supply, it is about time that we take concrete steps to save power. Apart from being conscious about the usage of power and water at home, one can employ pollution-free and cost-effective power solutions at our homes. Solar power solutions and wind power solutions are the two of the most efficient solutions that can replace the conventional power solutions employed at our homes.

These solutions can help you combat power outages, reduce your electricity bills, and also help the environment.

This article will explore the cost-effective wind power solution that you can employ at home.

Wind power solutions work best when the following conditions are met:
• You have a house or farmhouse spread over a big area. Typically, wind power solutions are employed in areas that spread over an acre.
• The average wind speed in your area is around 11 miles per hour. If you stay in a place that has little wind flow, your system will not work. Consult an expert before installing the wind power solution at home.
• You need to draw water from external sources. You can install a wind power system even when you do not need to draw water from outside. However, if you need to draw water from outside on a regular basis, a wind power system offers the best solution.
• Your house needs a lot of uninterrupted power supply. Combating those power outages is easy with the pollution-free wind power systems. You need no longer worry about a break in your work because of a power uncertainty.

A typical wind power system comprises of a tower and five blades to churn out wind energy. The length of the wind tower varies depending on the location of your house. You may need a longer tower if you are in low-wind zone; you can work with a shorter tower if you live by the beach. Using a wind generator, this wind energy can be converted into useful electrical energy to be employed at home for running various electrical appliances. You can even store the power generated for later use, making wind generators more efficient than convention power systems.

If you are confused with the wind power jargon, here’s a piece of information for you. The terms, wind mills, wind turbines, and wind generators are used to refer to the same machine.

Windmill design

What constitutes a windmill?

A windmill is device that converts wind energy into mechanical energy which is later converted into

electrical energy. A windmill typically consists of the following parts:

• The blades – A windmill can consist of any number of blades from four to 20. Some special wind

mills have higher number of blades.

• The tower – The tower holds the rotating blades high up in the air so that the winds rotate them.

• The shaft – The shaft is responsible for joining the blades with the tower and for the smooth

rotation of blades.

• The generator – The generator is what generates electricity from the mechanical energy. It also

stores power for future use.

• The base: The base of the windmill keeps it grounded to the earth.

What factors affect windmill design?
There are many factors that affect the design of a windmill. Let’s understand the major ones:

Wind speed: The wind speed can be accurately measured with the help of an anemometer. It is not

possible to determine the right kind of wind mill without knowing the accurate wind speed.

Wind direction: For designing a windmill, it is also important to know the direction from which

the wind flows most of the time.

• Change in wind speed: Apart from the constant speed of mind, it is required that you know how the

wind changes its speed.

• Change of wind direction: The direction of wind will not be constant, so it important to note the

way it changes its direction.

• Obstructions on the site: It is best t install a windmill at a place without many obstructions.

Look out for existing and potential structures that may affect the performance of your windmill.

• Wind turbulence: The movement of wind is not always predictable. However, it is a good idea to

understand the patter of wind turbulence in your site.

• Distance of wind activity from the ground: The height of the tower is dependent on the height at

which the wind is active.

What are the possible designs of windmills?
Aerodynamics determines the design of a windmill based on the factors mentioned in the section

above.

The designs of windmills vary in the following measures:
• Number of blades
• Shape of the blades
• Height of the tower
• Kind of generators
• Distance of the installation spot from the ground
• Distance between the tower and the generator
