Wind Power

Wind power is derived from the conversion of wind energy to become a useful form of energy to propel ships, make electricity or pump water. Wind is a renewable source of energy that is widely available and produces no harmful emission during operation.

Is Diesel generator set a renewable energy sources?

Not if it uses fuel derived from fossil oil deposits or other fossil fuels which are not renewable. If it uses bio fuel then that is renewable, as a new crop grows every year.

Example of wind force?

Hurricane force winds are an example of strong wind forces, which can reach speeds of 74 mph (119 km/h) or higher. These winds can cause significant damage to buildings, trees, and infrastructure due to their powerful nature and high velocity.

Why do cities heat up?

I suppose you mean why are cities usually hotter than surrounding open country areas? This is due to several effects: buildings absorb more heat from the sun, buildings are usually heated inside, dense road traffic produces heat and in narrow streets this can't easily escape. In summer conditions many buildings have air conditioning. this keeps them cool inside but the heat rejected to the outside can only appear in the general atmosphere in the city.

How will wind energy be used in the future?

There is no telling how wind energy will be used in the future. It could be used to replace car fuel in some way for example.

How is wind used to generate energy?

Power generation is done the same way weather (pun intended) it's drive is from the wind, water or fossil fuel. A generator produces electricity by spinning a rotor inside a stator. Not to get too deep, it's like a wind mill spinning a generator and causing electron flow.
The force of wind turns a large propeller which rotates a turbine that rotates magnets around a coil of wire to produce electricity. (Magnetic Flux)

How does a propeller generate thrust?

Technically it doesn't produce thrust, it produces lift the same as a wing - each blade of the propeller is a wing just like a helicopter blade so the plane is flying or lifting in a forward direction - the backwash of a prop is produced by the air being redirected by the airfoil of the prop. Lift (or forward motion) is created by making the air pressure lower on the front of the propeller blade than the back so the aircraft is actually being pulled / pushed forward by air pressure rather than being pushed by thrust - thrust is created by the forceful ejection of fuel such as from a jet or rocket engine Not understanding why props work is why early ship propellers were so inefficient - before the principal of lift was discovered it used to be thought they worked by creating thrust, and so were designed by trial and error to create as much backwash as possible. But the backwash has little to do with how a prop works. It's one of the problems the Wright brothers had to solve with their first airplane - all props of the time were poorly designed - the brothers correctly realized the prop was a wing and designed their own props as such.

What is the science behind wind energy?

Wind energy is harnessed through wind turbines that convert the kinetic energy of the wind into mechanical power. The blades of the turbine capture the wind's energy by rotating, which then drives a generator to produce electricity. Wind energy is a renewable and sustainable resource that helps reduce greenhouse gas emissions and dependence on fossil fuels.

Was wind successfully used in the past?

Yes, it has been used for thousands of years by sail boats, and then by sailing ships. It has been used for hundreds of years by windmills to pump water.

It has been very successful because it is a renewable resource. Hi Mya!

Wind turbine prices?

A wind turbine costs around 48,000 to 65,000, currently. However, a turbine with a generating capacity of 10 kilowatts may lower a utility bill by anywhere from 50 to 90 percent.

How many wind farms are there in the world?

There are many wind farms in the world. Every country has its own set of wind farms. There is no such list for all the wind farms in the world. However you can go through the list of Top 10 Biggest Wind Farms in the world in the given link.

What kind of fossil fuel do wind turbines need to produce electricity?

You obviously don't understand what fossil fuels are-coal, oil, natural gas. Wind turbines don't need any of these to produce electricity

Is hydroelectric power better than fossil fuels?

Hydroelectric power is better than fossil fuels because it is renewable. The water cycle ensures that there will always be water flowing downstream to turn turbines. Fossil fuels take millions of years to create.

Is wind power renewable?

Yes. This means we can use it as much as we can one day, and then it all comes back again next day ready to be used again. As wind power comes from the sun, it will be around a long time.

A:Wind is more properly described as an inexhaustible resource like sunlight or gravity.

But wind is generally regarded as being a source of renewable energy.

Can wind energy power cars?

Yes,

This would likely be done by first converting the wind energy into electricity and then using that electricity to power an electric car.

Though if you want a car powered directly by the wind, it would look more like a skate board with a sail, and so wouldn't really be considered a car. Though it is transportation by wind energy.

What kind of work can a windmill do?

Windmills were originally used to grind grain and pump water. Recently they are used to produce electricity. See the related link for more information.

How is wind power collected extracted removed from the environment?

By building a windmill to turn the wind power into electrical power

Can wind power from wind farms or turbines be stored?

In most cases it is not stored. But there are a number of methods (batteries, compressed air storage, hydro) in partial use and in experimental projects. One Japanese company is planning to build wind turbines with built-in batteries.

What energy do airplanes use?

Airplanes generally use gas (jet fuel) and sometimes the experimental ones use solar power. The fuel powers the engines or engine which make the plane fly.

It also powers the lights and other electrical appliances on a n aircraft through the

engine.

How much energy does a wind farm produce on average?

Large units are up to 2 Mwe now, though older ones are probably more like 1.5 Mwe. So just count the number of units and multiply. Of course that is the max assuming just the right amount of wind, on average it will be less.

Why is Nuclear Power so expensive?

Nuclear power plants require high upfront capital costs for construction, maintenance, and decommissioning. Strict safety and security measures, complex regulatory requirements, and long project timelines also contribute to the high costs associated with nuclear power. Additionally, challenges related to radioactive waste disposal and public perception can further increase expenses.
