Wind Power

A wind barrier, such as a row of trees or shrubs, helps reduce erosion on a farm by blocking the force of strong winds that can carry away soil particles. By creating a physical barrier, wind speeds are reduced, preventing soil erosion and promoting soil conservation. This can also help protect crops and reduce the risk of damage from wind erosion.

The energy of a moving object is proportional to the square of its velocity (speed) so fast moving air has much more energy which can be extracted (by a windmill or wind turbine to do work) than slow moving air.

Wind turbines do not use any fossil fuels to operate as they generate electricity from the wind. The amount of electricity generated depends on the wind speed and turbine efficiency, not on fossil fuel consumption.

It's a cleaner greener non-polluting way of generating electricity. The old ways of burning coal and oil are only adding to greenhouse gases and the warming of the planet.

It's also used there because they get a lot of wind and technology is making it cost effective to install and employ, even on farms, buildings, and city housing.

It depends on the technology. Current wind turbines placed in windy areas can produce electricity at 3-5 cents/kwh.

Newer technologies like high altitude turbines or vertical low velocity turbines claim they can produce for 2 cents/kwh or less.

That depends on the windmill.

Generally a single windmill is not sufficient, two or more wind mills are connected together to form a wind farm.

Generally a single wind mill can generate power only in kilowatts, not in megewatt.

An argument against the use of wind power is that it can be unreliable due to the intermittent nature of wind. This can lead to fluctuations in energy production and may require backup energy sources to maintain a steady supply. Additionally, concerns about the visual impact of wind turbines on landscapes and wildlife disruptions are also commonly cited.

Wind power is considered a clean and sustainable energy source that produces electricity without emitting carbon dioxide or other greenhouse gases. While the construction and maintenance of wind turbines can have minor environmental impacts, such as bird collisions, overall wind power has a much lower environmental footprint compared to fossil fuel-based electricity generation, making it a more environmentally friendly option for producing electricity.

Wind can contribute to weathering by carrying abrasive particles (like sand) that can wear away rock surfaces through abrasion. Wind can also transport fine particles that erode softer rocks through a process called deflation. Additionally, winds can enhance chemical weathering by bringing in moisture or gases that react with rock surfaces.

Wind turbines can be good for the environment because they use a completely renewable source of energy. Once installed, running costs are lower than many other electrical generation systems. Wind power avoids carbon dioxide emissions during operation.

However, all structures have an environmental impact. Many people complain of the visual impact as well as damage to local eco-systems. They are often placed in remote locations and access roads may need to be built for construction and maintenance.

The unreliable nature of wind also means that other power generation sources cannot be de-commissioned as they are needed for all periods when wind is not available.

The balance between negative and positive impacts on the environment needs to be carefully considered in each case.

an example of prevailing winds is like when you lick your finger to see which direction the wind is...

Ohm's Law and Watt's Law are important for wind turbine technicians to understand because they help in calculating and understanding the relationship between voltage, current, resistance, and power in wind turbine systems. This knowledge is crucial for troubleshooting electrical issues, optimizing system performance, and ensuring the safe operation of the wind turbine.

The lateen sail increased a sailor's ability to sail effectively into the wind, rather than decreasing dependence on the wind's force. By allowing for better maneuverability and efficiency in changing wind conditions, the lateen sail revolutionized sailing techniques and made it easier to sail against the wind.

Yes, geothermal energy can be harvested by tapping into the heat stored beneath the Earth's surface through drilling wells to access hot water and steam. This heat can then be used for various purposes, such as generating electricity or heating buildings. Geothermal energy is a renewable and sustainable source of energy that has the potential to provide a stable supply of power.

Mass movement refers to the process of gravity-driven movement of rock, soil, and debris down slope. This includes landslides, rockfalls, mudflows, and other mass wasting events. Factors such as slope steepness, type of material, and the presence of water can contribute to mass movement.

It's not (unless you mean solar wind which sends charged particles shooting through space where the collide with gas in the Earth's atmosphere to form Auroras).

Solar Energy is an example of renewable energy, like wind and water power.

yes wind blows all the time....it might be not as windy to see.... but does wind is like water you dont know if it moving or not .but its tiny particules are always moving....with little movement

It depends whether the shore is North, South, East or West of the sea.

The antitrade winds, also known as the westerlies, can be found in the mid-latitudes of both hemispheres between 30 and 60 degrees latitude. They flow from the west towards the east and are responsible for the movement of weather systems in these regions.

The answer was potential energy, which surely is wrong. The energy generated is, self evidently, mechanical energy. This can then be used directly or indirectly to generate other forms of energy, typically water flow is converted directly into mechanical then pure electrical energy in a generator turbine, as at a Hydroelectric power station.

Variable wind refers to wind that changes direction and speed frequently within a short period of time. It is often associated with unstable weather conditions and can make it challenging to predict the wind's behavior. Pilots and sailors must be particularly cautious when dealing with variable wind to ensure safe navigation.

approaching strong low-pressure system. These conditions often occur when a cold front is moving into an area, bringing unstable atmospheric conditions with it. Wind and thunderstorms are common along and behind the cold front as the contrasting air masses interact.

The velocity of the winds blowing at 89 miles per hour during a storm on the North Carolina coast is 89 miles per hour.

The problem with wind energy is that it does not produce much electricity. Wind does not flow at all places. So having wind energy as a major source of electricity is not a option.

Many localities in California have geographical constraints such as mountainous terrain or dense vegetation that make it challenging to build wind farms. Additionally, environmental concerns, such as impacts on wildlife habitats or migratory bird routes, can also limit suitable locations for wind farm development. Finally, navigating complex permitting processes and local opposition can further restrict the number of acceptable sites for building wind farms in California.
