How the Wind Turbines Operate to Generate Power

March 14, 2010 Leave a Comment

Many times when we think of wind energy, the first picture that surfaces is those large windmills out on farm land around the country. Have you ever wondered how they work? They really aren’t hard to understand, it’s just a few blades connected to a shaft that rotates and creates power. We make it sound easier then it is, but we’ll get into a little more detail in a minute.

Here’s a better example. Do you remember those little windmills you could stick in the front yard? Wind turbines work the same way. Obviously the technology is extremely better then those things we remember as kids, but the concept is to use wind and turn it into energy. While windmills are common, there are other terminologies used when electricity is generated. Whether it’s a wind power unit, a wind energy converter, or wind generator, they’re all the same.

One type of turbine is the HAWT which just stands for Horizontal-axis wind turbine. They are composed of the rotor shaft plus a generator which are both located on top of the tower, these are positioned to face into what wind there is. Larger turbines normally utilize a sensor along with what is called a servo motor. These usually contain a gearbox, and this helps the slow-speed rotating blades go faster which is more effective for powering the electric generator.

The turbines actually have to be pointing upwind if they’re going to create a substantial amount of power. However, it’s important to understand that these are extremely durable and they’re built to be safe. In fact, if you’re up-close and personal with one, you’ll notice the blades are built in front of the shaft so when turbulence hits or strong winds, it won’t collapse.

If you don’t have access to a HAWT, then the vertical-axis version (VAWTs) will be used. These are set up so the rotor shaft is in a vertical position. The benefit around this option is that the turbines don’t have to be situated against the wind in order to be efficient. Most people utilize this option when the wind tends to come from various directions throughout the day.

Unfortunately it’s extremely difficult to have the VAWTS mounted onto the high towers. So you’ll find these installed around the base of the tower.

When you see these towers, none of them are small. It is recommended that they be at least 100 feet high so they can get an increase in energy.

If you want to truly do your part and take advantage of a renewable resource, try combining it with solar power as well. It will allow you to reduce your energy costs, help keep the environment cleaner, and let everyone around you breathe cleaner air.

Why Wind Energy Outshines other Alternative Fuels

October 28, 2009 Leave a Comment

Among all the energy that can be generated and renewed, wind energy is the one that has great abundance and is always present. Other energy, like the fossil fuels, will become depleted and may disappear over time and usage, but the wind will always stay.

It will be hard to forget the period when gas shortages and the high fuel prices overcame the economy. With wind power, this crisis will not happen again although the competition is really fast progressing. Even fuel shortages in the future will no longer happen if wind power is being generated throughout the world.

Competition against the fossil fuel generation is already taking place and many wind energy bids are being won, able to prove that increased fuel costs just are not in their future equation. Once the initial equipment is in place, the costs remain steady. What a great feeling.

Breathing easier while taking care of the environment is what wind power is aiming for. Without spending too much, this operation will reduce pollution and air contamination brought by mercury and other pollutants from the power plants. Health-related problems like asthma and respiratory illnesses are expected to go lower too as the air becomes clean again through the use of the wind power.

As wind power is continually developed, this power has become available also for other applications like for the powering of homes, businesses and farms. The energy from wind also provides energy to areas where the situation is remote. This energy is applied to provide power to pump water and enable operation of telecommunication sites.

Conventional plants that generate their power from fossil and nuclear fuels use vast amounts of water for cooling. You will not find wind turbines taking fresh water. 77% of our fresh water is presently being used as part of our need to produce power, the old way and could be given back for more urgent needs.

The benefits of wind energy ia now experienced by people in the rural areas and urban areas. The power from the wind turbine is now being used in the urban areas at an affordable price. The good thing with the turbine is that the rotating turbines do not affect the crops and livestock in urban areas.

But for all of the reason listed above, public support ranks at the top of the list. People are tired of the games with everyday living expenses and want options that are simple, well defined and cost effective. Wind generation supplies this and much more. Maintenance will not be as high or nearly as complicated, it is a source of energy that does not have to relied upon by a worldwide cartel and national security will be much more controllable with everything being homegrown and kept at home. Wind power as we know it today is probably just the tip of the iceberg in what technology will come up with for wind tomorrow but one thing is for sure-wind energy is here to stay.

Photovoltaic Solar Or Electromagnetic Induction Energy

The earth has been very generous by offering us so many renewable sources of energy for our needs and creating alternative energy in many different forms. All over the world, people have used renewable power in one way or another but often only where mechanical electricity, powered by petroleum was not easily available.

We must seek to develop, store and generate the earth’s current form into usable power for our needs. Even though the wind, sun, and even the earth itself will never stop providing us the energy we desire. As our fossil fuel continues to be depleted, we seek with urgency to find a way to transition into alternative energy sources.

To transform these forms of energy into alternative energy is not really difficult. It has been actually utilized and done by people centuries ago. The fossil fuels were developed and turned into gas, diesel, and petroleum blends that are useful and needed nowadays. The problem is the costs it will take to do this kind of process.

It may be unfamiliar to all of us but this kind of transitioning energy is what the world needs today in order to preserve and protect the world from the worsening condition of global warming.

This transitioning is very useful and helpful to all of us. An example of this useful alternative energy is the solar power. Solar power can be generated into electricity, which is needed everywhere but is very expensive. By using solar electricity, people do not need to pay for electricity power since solar comes from the sun. But one thing that limits the development of this is the costs involved in making the necessary equipments to be able to convert the solar energy into electricity. This is what all of us should ponder and decide on.

Michael Faraday, a British scientist discovered electricity back in the 1800’s. Electricity was the same then as it is today. With even different methods of changing energy into electrical energy, the most common is the induction electromagnetic. That is when kinetic energy is transformed into electricity. To just put the basics of electricity to work for us in a different way will take a bit of training, skills, and education.

When it comes to solar power, the photovoltaic technology is the most popular and fast growing. But since the solar panels for photovoltaic technology is very expensive, only few were able to afford its price and maintenance. This PV solar panel is known to have been used in rich countries like Japan, Germany, and some states in USA like California and New Jersey. If other countries will develop this technology into market which everyone can afford, then, within the next few years, the solar power will be available to places where it is more practical than using petroleum fuels.

Through our mistakes and learning a lot about new products, we will find a better way to create a source of power. Our children have a lot of knowledge in how to save our earth by not polluting the air that is to protect us. Children are starting to appreciate the wind, the sun, and the earth. As soon as we can start to generate alternative renewable fuel, the better our planet will be.
