Wind Power

Size matters with wind turbines because larger turbines are more efficient at capturing wind energy due to their increased rotor diameter and taller tower height. This allows them to generate more electricity at lower wind speeds and produce higher energy outputs. Additionally, larger turbines benefit from economies of scale, making them more cost-effective than smaller turbines in terms of energy production per unit.

Of course new generation wind turbine has to face wind.The concept of wind turbine is this that wind has kinetic energy, and this energy is converted by WTG by rotary blade into mechanical energy through gear box then again into electrical energy through generator. Here mainly wind is the main criteria, which rotates blade in variable speed depends upon wind density. More density and wind speeed more power will be generated.

Besides this there are many versions of wind turbine, Upwind means new generation wind turbine normally we observed, In Down wind turbines turbines has no relation with wind perpendicular to wind.

I think you must have got the answer.

The conversion of wind energy into a useful form of energy is called the WIND... ENERGY. Have to add the ellipsis for it to work.

When energy is created from wind turbines the energy is created from the atmospheres wind currents and no chemical processes are required. With no chemical processes(burning) involved the atmospheres chemical composition is not altered. Burning fossil fuel, simply put is the chemical process of changing a form of concentrated carbon into heat and carbon dioxide. Ancient life on the planet absorbed the carbon dioxide from the atmosphere and time and natural processes sequestered the carbon from the ancient life into coal and oil reserves. When you burn the fossil fuel you are placing the carbon, that was once sequestered through the millions of years Earth has had life, back into the atmosphere thus changing the composition of the atmosphere. The results of putting the carbon back into the atmosphere is debated.

Example A: A pin-wheel is attached to a generator. The wind blows the pin wheels blades and the generator makes electricity. This electricity runs into a coil and the energy is transferred into heat and you warm your hands up.

Example B: You have a dead stick from a tree in your yard that grew for a year and fell off the tree. During that year the tree converted energy from the sun and the carbon from the air to create the stick. You burn the stick and warm your hand.

Wind turbines typically require a minimum wind speed of about 7-10 miles per hour to start generating electricity. The optimal wind speed for producing the maximum amount of electricity is around 25-35 miles per hour. Turbines are designed to automatically adjust their blade angles to capture the maximum energy from varying wind speeds.

Betz' Law is related to wind turbines. Developed by German physicist Albert Betz, it simply states that the maximum energy that can be captured by any wind turbine is 59.3 percent of the kinetic energy of the wind.

The original source of the energy in wind is the sun, which creates temperature differences in the atmosphere leading to air movement. For flowing water, the source of energy is typically the sun as well, which drives the water cycle and creates precipitation that fills rivers and streams.

the sun, it heats air, hot air rises up creating a vacuum for cooler air to blow and take up the vacuum space..sun gets its energy from fusion of helium atoms, they got their energy from the big bang and no one knows what happened before that.

In British slang, "gets the wind up" means to become nervous, anxious, or afraid. It suggests feeling unsettled or worried about something.

Wind power is considered renewable because it relies on the natural and continuous movement of air masses caused by the uneven heating of the Earth's surface by the sun. As long as the sun continues to shine, wind energy will be available. Additionally, wind turbines do not consume any finite resources and produce no greenhouse gas emissions during operation.

Wind turbines are not 100% efficient due to factors such as air resistance, mechanical losses in the turbine components, inefficiencies in the generator, and variability in wind speed. The Betz limit also imposes a theoretical maximum efficiency of 59.3% for converting kinetic energy in the wind into mechanical energy.

For me it is the fear of it coming apart and flying through the area I'm in causing severe harm..I also had a reoccurring dream as a child about them.they have always been frightening to me and are now more popular in my area : (

Wind power is unreliable. Fossil fuels can be used in greater quantities when in higher demand; we don't get to pick when the wind is effective. You can only put wind turbines where there is a stable amount of wind constantly. For example, a place shielded from winds would not make much power at all, causing in a power deficit.

Solar energy affects human health by triggering production of vitamin D within the body. Solar energy is also necessary for plants to grow; these plants and the animals that eat them provide food sources for humans.

Solar power uses photovoltaic cells to convert sunlight into electricity, while wind power uses turbines to convert the kinetic energy of wind into electricity. Solar power is dependent on sunlight, whereas wind power is dependent on wind speed and consistency. Both are renewable sources of energy, but they rely on different natural elements for generation.

Wind turbines convert energy from the sun into electricity indirectly by harnessing the sun's heat through uneven heating of the Earth's surface, causing air currents (wind) to form. The wind turns the turbine's blades, which spin a generator to produce electricity.

The spines on a wind turbine are called blades. These blades capture the energy from the wind and convert it into rotational motion to generate electricity. The design and length of these blades play a crucial role in determining the efficiency and power output of the wind turbine.

The largest wind turbines can reach up to 260 meters (853 feet) in height. These turbines are typically found in offshore wind farms where the taller height allows them to capture more wind energy at sea.

The height of a wind turbine tower typically ranges from 200 to 300 feet, although some can be taller. The height is important for maximizing the turbine's exposure to wind at higher speeds, which increases energy production.

Windmills typically have three blades because it strikes a balance between efficiency and cost. Three blades have been found to be the most efficient design for capturing wind energy while minimizing material and construction expenses. Additionally, a three-blade configuration allows the windmill to operate smoothly and withstand varying wind conditions.

The sun's energy is the primary driver of wind patterns on Earth. As the sun heats the Earth's surface unevenly, air masses of differing temperatures and pressures are created, leading to the movement of air which we feel as wind. In this way, the sun's energy is indirectly responsible for creating wind.

Nuclear reactors and wind turbines both vary in size and the amount of power they can generate, so an exact answer is really not possible.

But, a nuclear reactor can typically generate in the neighborhood of 1100 Megawatts of power, and as of 2011, a typical wind turbine installed on a large wind farm can generate in the neighborhood of 2 Megawatts of power.

So dividing 1100 by 2, you get 550. But this isn't the answer you want because wind turbines don't generate at their full capacity most of the time (while nuclear reactors do.) It would take 550 wind turbines to equal one nuclear reactor if they both operated at their maximum capacity all the time, which is not the case.

To correct for this, you need adjust by what's called the capacity factor. For nuclear reactors this is around 90%. That means over the long run, they generate electricity at 90% of their maximum. The capacity factor for large wind turbines is much lower, 30-35%. So 90%/30% is 3, and we need to multiply the 550 number by 3 to get the real equivalent.

550 X 3 = 1650.

So a reasonable number to quote for the number of turbines that equal one nuclear reactor is 1650.

Wind itself does not generate electricity, but using wind turbines it is converted into mechanical energy and the mechanical energy is converted into electrical energy.

"Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. Take a look inside a wind turbine to see the various parts. View the wind turbine animation to see how a wind turbine works."

Wind power isn't stored. It is immediately generated into electricity that goes straight into the power lines. This is why there has to be power lines in and area for it to be able to have a wind farm.
