Wind Power

A wind up toy uses mechanical energy. When you wind up the toy, you are storing potential energy in a spring or other mechanism. As the spring unwinds, it releases this stored energy, which is then converted into kinetic energy that powers the toy's movement.

The winds in a tornado spin, so the wind itself can come from any direction. Except for rare cases, tornadoes in the northern hemisphere rotate counterclockwise while those in the southern hemisphere spin clockwise.

Wind turbines may not turn on windy days due to maintenance or repair work, lack of grid demand for electricity, or environmental restrictions that prevent operation. Additionally, if the wind speed is too low or too high for the turbine to efficiently generate power, it may remain stationary.

They don't really save energy, per se. They capture wind energy, which is considered a renewable resource. This reduces the need to burn fossil fuel to satisfy the same energy needs, and arguably results in lower greenhouse gas emissions.

The turbine is solidly connected to the generator, which is similar to a very large AC generator that you have in a car, but produces a high voltage output, usually something like 20 kV. The whole assembly rotates at a rate to produce either 50 Hz or 60 Hz AC depending on the system it is part of.

Wind Turbines control system controls Pitch of blades to maintain optimum speed in all wind conditions, if wind is too fast, turbine's brakes will be automatically engaged to slow it down or even stop it in case of storms, if the brakes or control system fails, it will rotate freely and ultimately breakdown under stress from large centrifugal forces.

Wind is a form of renewable energy that is produced by the differential heating of the earth's surface. This causes air to move from one place to another, sometimes with a lot of force. This energy can be harnessed by employing wind turbines to generate electricity from wind energy.

Wind energy is in turn a product of Solar energy. The differential heating of the earth's atmosphere is a result of the solar energy impacting on the earth's surface which receives the sun's rays at different angles at different locations at different times of the year. In fact, all forms of renewable energy except Geothermal energy are derivatives of Solar energy.

-- Windmill or water-wheel turns generator

-- Generator charges battery

-- Energy stays in battery until needed

-- Battery operates lights at night when wind dies down or crick dries up

An electrical motor converts electrical energy into kinetic energy by using magnetic fields to produce motion in a mechanical component, such as a rotor or shaft. This conversion process allows the motor to drive various machines and devices by transferring motion based on the flow of electricity through the system.

The speed at which the blades on a windmill spin can vary based on factors such as wind speed and design of the windmill. On average, windmill blades typically rotate at speeds ranging from 10 to 20 revolutions per minute (RPM) in low wind conditions, and can reach speeds of 50 to 70 RPM or higher in stronger winds.

Yes, a round magnet rotating in a coil of wire can produce electricity through electromagnetic induction. As the magnet spins, it generates a changing magnetic field that induces a current in the coil according to Faraday's law of electromagnetic induction. This current can be harnessed as electrical energy.

Wind energy is a form of kinetic energy that is derived from the movement of air molecules in the atmosphere. This kinetic energy is harnessed using wind turbines to generate electricity.

Electricity can be generated from a turbine through the process of converting mechanical energy into electrical energy. When a turbine spins, it rotates a shaft that is connected to a generator. The rotation of the shaft inside the generator creates a magnetic field, inducing an electrical current in the wires of the generator which generates electricity.

Because it is transfered to a long distance with less loses as compared to other form of energy

A2. Electrical energy can be transported across "empty" space and can be stored and can be transformed to other forms of energy.

A3. Electrical, much like geothermal, is a natural energy source that can be harvested from lightning and other weather related sources. In theory, we should be able to use these sources to create usable energy: the source producing more energy that it takes to harvest it in a plant.

People rely on wind as a renewable energy source for generating electricity. Wind is abundant and can be harnessed using wind turbines to produce clean energy without emitting greenhouse gases. Additionally, wind power can help reduce dependence on finite fossil fuels and mitigate climate change.

A concern when windmill farms are used to generate electricity is their impact on wildlife and ecosystems. The noise pollution caused by wind turbines is not typically a significant concern, as they are designed to operate quietly.

In wind energy, the motion of the wind rotates the blades of a turbine. This rotation is then transferred to a shaft connected to a generator. As the shaft turns, it spins the generator's rotor, which converts the mechanical energy into electrical energy through electromagnetic induction.

Wind power is harnessed by using wind turbines to convert the kinetic energy of the wind into electricity. The rotating blades of the wind turbine drive a generator, which produces electricity that can be used to power homes, businesses, and communities. Wind power is a clean and renewable energy source that can help reduce reliance on fossil fuels and decrease greenhouse gas emissions.

A windmill typically produces electricity by converting wind energy into rotational mechanical energy, which then drives a generator to produce electricity. This electricity can be used to power homes, businesses, or other devices that require electrical energy.

Yes, a windmill uses the kinetic energy of the wind to spin its blades, which in turn drives a generator to produce electricity. The kinetic energy of the wind is converted into mechanical energy and then into electrical energy through this process.

No, a penny dropped from the Empire State Building would not go through a person's body. While it would fall with enough force to potentially cause injury, the penny's small size and shape would not allow it to penetrate through a person's body.

Some negative effects of using wind energy include potential harm to wildlife, including birds and bats, from collisions with wind turbine blades, noise pollution for nearby residents, and visual impact on landscapes. Additionally, there may be concerns about the manufacturing and disposal of wind turbine components impacting the environment.

The amount of energy produced by a wind turbine at 28 mph will depend on the specific characteristics of the turbine, such as its size and efficiency. On average, a wind turbine with a moderate wind speed like 28 mph can generate around 50-60% of its maximum output capacity. It is recommended to consult the turbine manufacturer's specifications for a more precise estimate.

From a survey of 100 people 78% of them would not like a wind farm near them. But most of them don't mind it being anywhere else. Maybe for these negatives and positives...

Positives, - low maintenance, no by product (think nuclear) energy. flexible locations, long term, sustainable and consistent.

Negative - affects local landscape, doesn't work in slow wind OR too faster winds(!), no jobs provided, the oil companies barely get anything from it.
