What role does the sun play in the creation of wind farms?

User Avatar

Asked by Wiki User

The sun's heat causes uneven heating of the Earth's surface, creating temperature differences that lead to the generation of wind. Wind turbines in wind farms harness this wind energy to generate electricity. Therefore, the sun indirectly contributes to the creation of wind farms by driving the wind patterns that power the turbines.

How fast do you have to travel to catch fire?

User Avatar

Asked by Wiki User

It is not possible to catch fire due to speed alone. However, if an object is traveling at extremely high speeds in Earth's atmosphere, the friction with the air could generate enough heat to cause it to catch fire. The specific speed needed would depend on various factors such as the object's shape and materials.

When the wind speed is x meters per second the wind turbine generates twice as much power as it does when the wind speed is 10 ms Calculate the value of x Give your answer to 3 significant figures?

User Avatar

Asked by Wiki User

To determine the wind speed x at which the turbine generates twice as much power as at 10 m/s, you can use the cube law for wind turbines, which relates power output to wind speed cubed. Let P be the power generated at wind speed x and P0 be the power generated at 10 m/s. Using the cube law equation (P/P0 = (x/10)^3), plug in P/P0 = 2 to find x. (3 significant figures): x ≈ 17.3 m/s.

Why don't wind turbines work at night?

User Avatar

Asked by Wiki User

Wind turbines work whenever there is wind, regardless of the time of day. However, wind speeds tend to be lower at night, which can result in lower electricity generation. Additionally, wind turbines may be shut off at night for maintenance or safety reasons.

What is the theme for the wind and the sun?

User Avatar

Asked by Wiki User

The theme of "The Wind and the Sun" fable is that persuasion is more effective than force. The story illustrates how the Sun's gentle warmth is able to persuade the traveler to remove his cloak, whereas the Wind's forceful blowing fails to achieve the same result.

Why do bats die near a wind turbine?

User Avatar

Asked by Wiki User

Bats die near wind turbines because they may collide with the rotating blades, which can cause fatal injuries. The fast-moving blades create a low-pressure zone that can cause barotrauma in bats, leading to internal injuries and death. The behavior of bats, such as feeding or mating, may also bring them closer to the turbines, increasing the risk of collision.

What do reflectors do in solar power?

User Avatar

Asked by Wiki User

Reflectors in solar power systems are used to redirect and concentrate sunlight onto solar panels or receivers, increasing the amount of energy captured. By focusing sunlight onto a smaller area, reflectors can boost the efficiency and output of a solar power system, especially in locations with low sunlight intensity.

How does wind energy derives its energy from the sun?

User Avatar

Asked by Wiki User

Wind energy is derived from the sun because the sun's uneven heating of the Earth's surface creates temperature and pressure differences, which in turn generate wind. Wind turbines convert the kinetic energy of wind into mechanical power, which is then converted into electricity. Thus, wind energy ultimately originates from the sun's role in creating natural wind patterns.

What kind of winds cause avalanches?

User Avatar

Asked by Wiki User

Strong and sudden winds, such as gusts during a storm or foehn winds, can cause avalanches by depositing snow in unstable layers on steep slopes. These winds can create wind slabs that are prone to breaking loose and triggering avalanches.

Who founded solar power?

User Avatar

Asked by Wiki User

Solar power as a technology has been utilized for centuries, but Alexandre Edmond Becquerel is often credited with discovering the photovoltaic effect in 1839, which laid the foundation for modern solar power. Charles Fritts is credited with creating the first solar cell in 1883, marking an important milestone in the development of solar energy.

Why does wind power need sunlight?

User Avatar

Asked by PR1NCESSNO1

Wind power does not directly require sunlight for operation. Wind turbines generate electricity by harnessing the kinetic energy of the wind. However, sunlight is indirectly linked to wind power as it influences weather patterns and ultimately drives wind movement.

How does the sun's energy create wind?

User Avatar

Asked by Wiki User

As the sun warms the Earth's surface, the atmosphere warms too. Some parts of the Earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air, which weighs less than cold air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.

Who invented solar pannels?

Asked by Wiki User

Solar panels were invented by Bell Labs in 1954. The team was led by Gerald Pearson, Calvin Fuller, and Daryl Chapin. They created the first working silicon solar cell, which eventually led to the development of modern solar panels.

Where does the earth's wind power come from?

User Avatar

Asked by Wiki User

The Earth's wind power primarily comes from the uneven heating of the Earth's surface by the sun. As air near the Earth's surface becomes heated, it rises and cooler air moves in to take its place, creating wind. This movement of air generates kinetic energy that can be harnessed for power generation.

How does topography effect where to place a wind farm?

User Avatar

Asked by Wiki User

Topography affects wind farm placement by influencing wind patterns. Areas with terrain features like hills or ridges can create wind turbulence or block the wind flow, making them unsuitable for wind turbines. Conversely, locations with unobstructed, consistent wind flow, such as coastal areas or open plains, are ideal for placing wind farms.

How does wind energy contribute to any form of pollution on land?

User Avatar

Asked by Wiki User

Wind energy does not directly produce pollution on land. However, during the manufacturing, transportation, installation, and maintenance of wind turbines, some pollution from greenhouse gas emissions and waste generation can occur. Additionally, if wind turbines are not properly disposed of at the end of their life cycle, they can contribute to pollution on land.

Why is wind power solar power and geothermal power considered renewable?

User Avatar

Asked by Wiki User

Wind power, solar power, and geothermal power are considered renewable because they rely on naturally replenishing resources. Wind is generated by the sun heating the Earth's surface, creating air movement. Solar power directly harnesses sunlight, which is an inexhaustible energy source. Geothermal power taps into the heat stored in the Earth's core, which is continuously produced through the decay of radioactive materials. These sources do not deplete over time and can be used indefinitely without causing harm to the environment.

What are geotropic winds?
