Wind power can produce electricity and so Wind Turbines can supply electricity to an Electricity Grid which could be a Smart Grid too. The following media presentation is very useful because it explains something important for beginners to know. Wind Power needs land and there is a formula to show that simply adding more wind turbines in a given are may not produce the energy expected by someone who is unfamiliar with wind technology. 


Of course, we also need wind and there are ways to measure the wind by a device called an Anemometer which is important because it helps the Wind Turbine to more accurately face the wind because wind direction can change. You will see an Anemometer installed on the top of this Wind Turbine. The presentation shows us how wind forcing the turbine blades to spin produces mechanical energy which is converted to electricity by a magnetic rotor rotating inside copper wire loops working with a transformer to increase the voltage. The electricity is carried through cables to a local substation and transmission line.


Since this site is about Meter Data, we thought it would be appropriate to mention a little more about the meter called the Anemometer. Anemometers are not alike and they come in all shapes, forms and sizes.  It is probably going to be extremely important for someone planning to install multiple turbines in a specific location (wind farm) to first obtain accurate and reliable data on wind speed and direction over a period of time i.e. Wind Data. They might face different kinds of challenges depending on where the measurements are taking place because of temperature changes, weather conditions and wind velocities. The wind can be blowing extremely softly and all of a sudden increase in velocity. This means that the Anemometers must be able to work reliably in conditions that change. Operators might be using either mechanically based wind meters or even non mechanical types using sonic technology as explained in the next media presentation. There will most likely be a personal preference in what type of technology will be used to gather  Meter Data i.e. wind speed data as well as wind direction data.

Back to Wind Turbines. Some of us have probably never seen a Wind Farm but Californians, for example, will probably be very familiar with them.  Wind Turbines are classified as an alternative source of energy and previously many of them were installed due to oil crisis fears. Over the last decade there have been moves to improve the efficiency of turbines and  manufacturing capabilities of suppliers  so that costs can be lowered and more efficient electricity can be produced by them. There is now a great interest in wind power as part of a future source of energy and many enthusiasts are even installing smaller versions in their own backyard.
