Energy

About: <p><strong>What Is Wind Energy? Wind energy (or wind power) refers to creating electricity using the wind or air flows that occur naturally in the earth&rsquo;s atmosphere. Modern wind turbines are used to capture kinetic energy from the wind and generate electricity.</strong></p> <h2>Wind Energy: Three Main Types Of Wind Energy:</h2> <ul> <li>Utility-scale wind:&nbsp;Wind turbines that range in size from 100 kilowatts to several megawatts. The electricity is delivered to the power grid and distributed to the end-user by electric utilities or power system operators.</li> <li>Distributed or "small" wind:&nbsp; Single small wind turbines below 100 kilowatts used to power a home, farm, or small business directly and are not connected to the grid.</li> <li>Offshore wind:&nbsp;Wind turbines erected in large bodies of water, usually on the continental shelf.&nbsp;Offshore wind turbines are more massive than land-based turbines and can generate more power.</li> </ul> <h2>How Wind Turbines Work</h2> <p>When the wind blows past a wind turbine, its blades capture the wind&rsquo;s kinetic energy and rotate, turning it into mechanical energy. This rotation turns an internal shaft connected to a gearbox, which increases the speed of rotation by a factor of 100. That spins a generator that produces electricity.</p> <p>Typically standing at least 80 meters (262 feet) tall, tubular steel towers support a hub with three attached blades and a 'nacelle,' which houses the shaft, gearbox, generator, and controls. Wind measurements are collected, which direct the turbine to rotate and face the strongest wind, and the angle or "pitch" of its blades is optimized to capture energy.</p> <p>The Haliade-X offshore turbine features a 12 MW capacity, 220-meter rotor, a 107-meter blade, and digital capabilities is the&nbsp;not only the most powerful wind turbine in the world but also features a 63% capacity factor&mdash;five to seven points above industry standard. Capacity factor compares how much energy was generated against the maximum that could have been produced at the continuous full-power operation during a specific period. Each incremental point in capacity factor represents around $7 million in revenue for our customers over the life of a windfarm.</p> <p>A typical modern turbine will generate electricity when wind speeds reach six to nine miles per hour (mph), known as the cut-in speed. Turbines will shut down if the wind is blowing too hard (roughly 55 miles an hour) to prevent equipment damage.</p> <p>Over the course of a year, modern turbines can generate usable amounts of electricity over 90 percent of the time. For example, if the wind at a turbine reaches the cut-in speed of six to nine mph, the turbine will generate electricity. As wind speeds increase, so does electricity production.</p> <p>Another standard measure of wind energy production is called the capacity factor. This measures the amount of electricity a wind turbine produces in a given period (typically a year) relative to its maximum potential.</p> <p>For example, suppose the maximum theoretical output of a two-megawatt wind turbine in a year is 17,520 megawatt-hours (two times 8,760 hours, the number of hours in a year). However, the turbine may only produce 7,884 megawatt-hours over the year because the wind wasn&rsquo;t always blowing hard enough to generate the maximum amount of electricity the turbine was capable of producing. In this case, the turbine has a 45 percent (7,884 divided by 17,520) capacity factor. Remember&mdash;this does not mean the turbine only generated electricity 45 percent of the time. Modern wind farms often have capacity factors more significant than 40 percent, close to some types of coal or natural gas power plants.</p> <h2>Windmills vs. Wind Turbines</h2> <p>Sometimes people use the terms 'windmill' and 'wind turbine' interchangeably, but there are significant differences. People have been using windmills for centuries to grind grain, pump water, and do other work. Windmills generate mechanical energy, but they do not generate electricity. In contrast, modern wind turbines are highly evolved machines with more than 8,000 parts that harness wind's kinetic energy and convert it into electricity.</p> <h2>What Is A Wind Farm?</h2> <p>Often a large number of wind turbines are built close together, which is referred to as a wind project or wind farm. A wind farm functions as a single power plant and sends electricity to the grid.</p> <h2>How Does Wind Energy Get To You?</h2> <p>The turbines in a wind farm are connected, so the electricity they generate can travel from the wind farm to the power grid. Once wind energy is on the primary power grid, electric utilities or power operators will send the electricity to where people need it.</p> <p>Smaller transmission lines, called distribution lines, collect electricity generated at the wind project and transport it to larger 'network' transmission lines. The electricity can travel across long distances to the locations where it is needed. Finally, smaller distribution lines deliver electricity directly to your town, home, or business.</p> <p><strong>Before you go!</strong></p> <p><em><strong>Recommended:&nbsp;</strong><a href="https://www.whatsorb.com/energy/wind-turbines-learning-about-the-limits-of-this-renewable"><strong>Wind Turbines: Limits Of This Renewable</strong></a></em></p> <p><em><strong>Do you like this article about Gravitricity, or do you have a question or remark?

10 Best Home Wind Electricity Turbines 2020
We've all probably seen a windmill once: these enormous turbines generate energy in a green way, often to power communities and cities. But can you also imagine that you have your wind turbine, which only supplies your house with electricity? Your Own Energy Generator There are several windmills specially designed to power a single household and cover some or even all your monthly energy needs. Wind electricity is a well- known way to generate clean energy: are home wind electricity turbines our future? In this article, we tell you all about the ten best home electricity turbines of this year. Recommended: Urban Windmills: Wind Energy: The Future Or A Mere Eyesore? Wind energy. How does it work? Simply put: a wind turbine rotates and converts the released wind energy into electrical power. The continuous rotating movement, caused by the wind turbine blades, creates energy without releasing any harmful substances. Although wind energy is very trendy nowadays, the idea of wind energy is used for centuries. For example, flour used to be made in traditional mills: thanks to the rotating movement of the blades. Wind energy can play a crucial role in the ambition to use more sustainable energy sources. Downsizing Energy Costs And Other Benefits If you are considering a wind turbine for home use, you naturally want to know the pros and cons. The most significant advantage of having your windmill is, of course, the lowering of your energy bill. How much power you will eventually produce for home use depends entirely on the type of turbine and the wind speed on your site. If you assume the right weather conditions, a turbine that produces about 5 kW of energy can generate about 8,000 kWh per year. Other advantages of your wind turbine are that you cooperate in the fight against pollution, that you are not dependent on the energy grid, and that you can often count on subsidies from the government. {youtube}                                                                                  Wind Turbines 2020 Good to know: You would naturally prefer a home windmill as small as possible, but you should count on a diameter of about 13 (13 m.) to 18 feet (5,5 m.). Also, the wind turbine should ideally be placed in an area where strong winds often pass through so that you can enjoy all the above advantages. Another drawback may be the purchase price, but cheaper turbines can be unreliable and provide less power. You will have to spend between $ 30,000 and $ 70,000 to purchase a home wind turbine - and we have not yet included the installation costs. Based on the above calculation of 8,000 kWh per year, you can recoup the investment in about two to five years. Of course, that also depends on your energy consumption. Recommended: Vortex Bladeless Wind Turbine - The Future of Wind Turbines? Small Wind Turbines: Checks There are a few things you should check out if you want to install your wind turbine. First of all, it is good to research the rules in the area where you live: in some communities. You cannot install a home windmill; in others, you will get a subsidy for it. Also, try to map out your energy consumption as much as possible. This way, you can create a realistic picture of your future energy costs. And most importantly: check the weather conditions around your property. Is there enough wind? If so, you can be sure that your windmill can provide you with power all year round. If the mill you have in mind has a certification from the Small Wind Certification Council, you can surely buy the best quality wind turbine. The 10 Best Home Wind Turbines 1.

10 Best Home Wind Electricity Turbines 2020
Wind Turbines: Limits Of This Renewable
Wind energy is valuable to generate power, but how useful is it? Some researchers say they have evidence that the more you use it, the less is available. Wind Turbines Energy: Highly Overestimated The wind is everywhere, but does it have enough power to turn wind turbines? US researchers say it's highly overestimated. Amanda Adams of the University of North Carolina and David Keith of Harvard say that wind farms could eventually limit energy. They say the limitation is not due to the economy or technique, but it is one of the atmospheric physics. When the wind blows against a blade, and it continues to rotate, it will transfer energy to the blade. From there on, the power will slam into the turbine. That decelerates the wind. Harvested by advanced technical systems honed over decades of research and development, wind energy has become a mainstream energy resource. However, continued innovation is needed to realize the potential of wind to serve global demand for clean energy. Here, we outline three interdependent, cross-disciplinary grand challenges underpinning this research endeavor. The first is the need for a deeper understanding of the physics of atmospheric flow in the critical zone of plant operation. The second involves science and engineering of the most massive dynamic, rotating machines in the world. The third encompasses optimization and control of fleets of wind plants working synergistically within the electricity grid. Addressing these challenges could enable wind power to provide as much as half of our global electricity needs. Recommended:  Wind Turbines: Cheaper, More Efficient. Make Them Telescopic The Limits Of Renewable Wind Turbines: Wind Shadows Each turbine carries a 'wind shadow.' So, wind farm entrepreneurs have to make arrangements to place their turbines as far apart from each other as possible. They should not get in each other's way. After all, a group of wind turbines breaks the force of the wind and leaves a long trail where the wind is not as strong. This is called a wind shadow. The production depends on the calculations related to capacity and density. Commonly, a wind farm can handle an output of 2 to 4 watts per square meter, which is 2 to 4 megawatts over a square kilometer. Offshore wind farms involve complex optimization challenges, as numerous factors must be considered wind direction, water depths, erosion zones, foundation costs, physical obstacles, types of cables, cable loss, and the fact that the wind turbines do not cast 'shadows' on each other.

Wind energy is valuable to generate power, but how useful is it? Some researchers say they have evidence that the more you use it, the less is available. Wind Turbines Energy: Highly Overestimated The wind is everywhere, but does it have enough power to turn wind turbines? US researchers say it's highly overestimated. Amanda Adams of the University of North Carolina and David Keith of Harvard say that wind farms could eventually limit energy. They say the limitation is not due to the economy or technique, but it is one of the atmospheric physics. When the wind blows against a blade, and it continues to rotate, it will transfer energy to the blade. From there on, the power will slam into the turbine. That decelerates the wind. Harvested by advanced technical systems honed over decades of research and development, wind energy has become a mainstream energy resource. However, continued innovation is needed to realize the potential of wind to serve global demand for clean energy. Here, we outline three interdependent, cross-disciplinary grand challenges underpinning this research endeavor. The first is the need for a deeper understanding of the physics of atmospheric flow in the critical zone of plant operation. The second involves science and engineering of the most massive dynamic, rotating machines in the world. The third encompasses optimization and control of fleets of wind plants working synergistically within the electricity grid. Addressing these challenges could enable wind power to provide as much as half of our global electricity needs. Recommended:  Wind Turbines: Cheaper, More Efficient. Make Them Telescopic The Limits Of Renewable Wind Turbines: Wind Shadows Each turbine carries a 'wind shadow.' So, wind farm entrepreneurs have to make arrangements to place their turbines as far apart from each other as possible. They should not get in each other's way. After all, a group of wind turbines breaks the force of the wind and leaves a long trail where the wind is not as strong. This is called a wind shadow. The production depends on the calculations related to capacity and density. Commonly, a wind farm can handle an output of 2 to 4 watts per square meter, which is 2 to 4 megawatts over a square kilometer. Offshore wind farms involve complex optimization challenges, as numerous factors must be considered wind direction, water depths, erosion zones, foundation costs, physical obstacles, types of cables, cable loss, and the fact that the wind turbines do not cast 'shadows' on each other. The location of each turbine on a farm is also important to avoid that they so to speak 'steal' energy from the turbines behind them.

Wind Turbines: Waste From These Blade Runners?
Wind turbines are very reliable in generating usable energy. Besides, turbines are economically exploitable. However, there are disadvantages to a wind turbine.  The biggest downside is waste. For years the wind turbines are used to produce sustainable energy. But then there is that inevitable moment: the wind turbine is obsolete. And then what? History Behind Wind Turbines Just like the sun, the wind is an energy source. A wind turbine generates electrical energy directly for its use and can be returned to the grid. The concept of a windmill has been known for centuries. It was formerly used to drive a millstone or a waterwheel, for example. However, we can also drive a generator (large dynamo) directly, which generates electricity. In the last few years, the development of the windmill has grown, and the windmill, now often referred to as the wind turbine, is currently seen as the essential choice for generating clean electricity on a large scale.

Governments and corporations around the world have promised to use only clean energy by 2050. To accomplish this goal, we have to use wind energy, among others. Wind turbines generate electricity without polluting the air, without affecting the climate and without depleting resources. Some CO2 is released during construction, maintenance, and demolition of the turbine, but after 3 to 6 months of operation, a turbine has already saved that amount of CO2 emissions.

Therefore, you need a particular diamond-encrusted industrial saw to saw it into three pieces that can be tied back onto a trailer. Then they go to a particular garbage dump. Recycle Parts Of A Wind Turbine Fortunately, there are parts of a wind turbine that can be recycled. Many materials can even be reused for new mills. The pole and foundation are no problem. They consist mainly of metal and cement, which is easy to recycle. However, the problem lies in the blades. Twenty years ago, the windmills were a lot smaller.

Gravitricity: Energy Storage Too Good To Be True?
Energy

What Is Wind Energy? Wind energy (or wind power) refers to creating electricity using the wind or air flows that occur naturally in the earth’s atmosphere. Modern wind turbines are used to capture kinetic energy from the wind and generate electricity.

Wind Energy: Three Main Types Of Wind Energy:

  • Utility-scale wind: Wind turbines that range in size from 100 kilowatts to several megawatts. The electricity is delivered to the power grid and distributed to the end-user by electric utilities or power system operators.
  • Distributed or "small" wind:  Single small wind turbines below 100 kilowatts used to power a home, farm, or small business directly and are not connected to the grid.
  • Offshore wind: Wind turbines erected in large bodies of water, usually on the continental shelf. Offshore wind turbines are more massive than land-based turbines and can generate more power.

How Wind Turbines Work

When the wind blows past a wind turbine, its blades capture the wind’s kinetic energy and rotate, turning it into mechanical energy. This rotation turns an internal shaft connected to a gearbox, which increases the speed of rotation by a factor of 100. That spins a generator that produces electricity.

Typically standing at least 80 meters (262 feet) tall, tubular steel towers support a hub with three attached blades and a 'nacelle,' which houses the shaft, gearbox, generator, and controls. Wind measurements are collected, which direct the turbine to rotate and face the strongest wind, and the angle or "pitch" of its blades is optimized to capture energy.

The Haliade-X offshore turbine features a 12 MW capacity, 220-meter rotor, a 107-meter blade, and digital capabilities is the not only the most powerful wind turbine in the world but also features a 63% capacity factor—five to seven points above industry standard. Capacity factor compares how much energy was generated against the maximum that could have been produced at the continuous full-power operation during a specific period. Each incremental point in capacity factor represents around $7 million in revenue for our customers over the life of a windfarm.

A typical modern turbine will generate electricity when wind speeds reach six to nine miles per hour (mph), known as the cut-in speed. Turbines will shut down if the wind is blowing too hard (roughly 55 miles an hour) to prevent equipment damage.

Over the course of a year, modern turbines can generate usable amounts of electricity over 90 percent of the time. For example, if the wind at a turbine reaches the cut-in speed of six to nine mph, the turbine will generate electricity. As wind speeds increase, so does electricity production.

Another standard measure of wind energy production is called the capacity factor. This measures the amount of electricity a wind turbine produces in a given period (typically a year) relative to its maximum potential.

For example, suppose the maximum theoretical output of a two-megawatt wind turbine in a year is 17,520 megawatt-hours (two times 8,760 hours, the number of hours in a year). However, the turbine may only produce 7,884 megawatt-hours over the year because the wind wasn’t always blowing hard enough to generate the maximum amount of electricity the turbine was capable of producing. In this case, the turbine has a 45 percent (7,884 divided by 17,520) capacity factor. Remember—this does not mean the turbine only generated electricity 45 percent of the time. Modern wind farms often have capacity factors more significant than 40 percent, close to some types of coal or natural gas power plants.

Windmills vs. Wind Turbines

Sometimes people use the terms 'windmill' and 'wind turbine' interchangeably, but there are significant differences. People have been using windmills for centuries to grind grain, pump water, and do other work. Windmills generate mechanical energy, but they do not generate electricity. In contrast, modern wind turbines are highly evolved machines with more than 8,000 parts that harness wind's kinetic energy and convert it into electricity.

What Is A Wind Farm?

Often a large number of wind turbines are built close together, which is referred to as a wind project or wind farm. A wind farm functions as a single power plant and sends electricity to the grid.

How Does Wind Energy Get To You?

The turbines in a wind farm are connected, so the electricity they generate can travel from the wind farm to the power grid. Once wind energy is on the primary power grid, electric utilities or power operators will send the electricity to where people need it.

Smaller transmission lines, called distribution lines, collect electricity generated at the wind project and transport it to larger 'network' transmission lines. The electricity can travel across long distances to the locations where it is needed. Finally, smaller distribution lines deliver electricity directly to your town, home, or business.
