- The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. Winds have to be at least 17 mph strong to make the blades spin and thus produce energy. There will be times when they produce no electricity at all. Large wind machines have to be shutdown if the wind is too strong, to avoid damage. The only practical way to produce large amounts of power is to use hundreds of them in an array in a place where the wind is most constant, such as floating on platforms out to sea, as is being done in Sweden. They can not, as some people think, just be spread out and 'tapped' into the power grid.
- Many people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They disfigure the countryside and are generally ugly. Many people feel that the countryside should be left untouched, without these large structures being built. The landscape should left in its natural form for everyone to enjoy.
- Wind turbines are noisy. Each one can generate the same level of noise as a family car traveling at 70 mph.
- Large wind farms are needed to provide entire communities with enough electricity. For example, the largest single turbine available today can only provide enough electricity for 475 homes, when running at full capacity. How many would be needed for a town of 100,000 people?
- The huge blades pose a danger to birds. Many birds can instantly be killed because the fast spinning blades of the turbines can not be seen very well. (The turbines are now being built with larger slower-moving blades, so fewer birds are killed.)
- Wind turbines cannot be placed near cities (where they are needed the most) because of the noise. Suitable areas for wind farms are often near the coast, where land can be expensive.
- Right now (2277) wind power costs more than fossil fuel energy.
- They require more conventional power plants to address variability in wind-power production. A national grid would require other forms of generation - wave, tidal, solar, coal, gas, nuclear, etc - to guarantee a continuous supply.
What else can I help you with?
Are wind power and wind energy the same?
Yes, wind power and wind energy are often used interchangeably to refer to the electricity generated from harnessing the power of wind. Wind power is a renewable energy source that comes from converting wind into electricity through wind turbines.
What are the good and bad points about wind?
Good points: Wind is a renewable energy source that is abundant and widely available. It produces no greenhouse gas emissions during operation and helps reduce reliance on fossil fuels. Bad points: Wind energy can be intermittent, as wind speeds can vary. Wind turbines can also have visual and noise impacts on local communities and wildlife, and infrastructure costs can be high.
What are two differences between using solar energy and wind energy?
One difference is the source: solar energy comes from the sun, while wind energy comes from the movement of air. Another difference is the way energy is converted: solar energy is converted directly using solar panels, while wind energy is converted through wind turbines.
What three things affects the size and energy of a wave?
Three things that affect the size and energy of a wave are the wind speed, the duration of the wind blowing, and the fetch (the distance over which the wind blows uninterrupted). These factors determine the amount of energy that can be transferred to the water, resulting in different wave heights and strengths.
What is energy from wind called?
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.
What are bad things about wind turbines?
turbine is a one that is rotating motor which delivers the energy to machines
What type of things are sustainable besides energy?
solar energy

Why is wind an energy source?
Wind is considered to be an energy source because it moving and creating impact on the things around it. Wind can affects water sources for example.
Why is wind energy bad for us?
because of greg perez's mom
What did wind energy do?
Among other things it drives machinery.
What are some things wind energy powers?
houses can be one also other things
How your ancestors used wind energy?
They used wind for many things, like sailing boats, the wind blows the ails and the ship moves, they used wind to dry things like clothes.
What does an ill wind mean?
The quotation is "it is an ill wind that blows nobody any good." This is from Shakespeare. An "ill" wind would be a bad or unpleasant wind - but the quote means that even a bad wind can result in good things in the end.
What are bad things about wind electricity?
i dont know abut it i want the answer
How does wind store potential energy?
Wind (air) may have a bit of gravitational potential energy, since it's up there and not on the ground. But the real, substantial energy of wind, and the energy we take out of it to turn things and generate electrical energy, is its kinetic energy. That's the reason that 'windmill farms' are built in places with steady wind. If there's no wind, then there's no kinetic energy available to be robbed from it.
