Wind Power

Wind energy has been used by humans for centuries, dating back to ancient civilizations who used windmills to grind grain and pump water. The earliest recorded use of wind energy for power dates back to the 1st century AD in Persia and China. However, modern wind turbines for generating electricity were developed in the late 19th and early 20th centuries.

As the world continues to need more and more power, many countries are looking for alternative sources of power. Solar and wind energy are attractive sources of power because they would be cheap, and would not be harmful to the environment.

The Savonius turbine is of simple geometry and its construction is cheap. It starts rotating a llower wind speeds as compared to its counterpart wind turbines, having a high starting torque. It produces low noise and can make use of the wind flowing in any horizontal direction to its rotation. However, in spite of these advantages, this wind turbine faces one main disadvantage of having low efficiency.

Wind power isn't measured in watts. It takes a certain amount of wind to spin the blades. They can turn the angle of the wind turbine blades to help catch the wind. I beileve the wind has to be at least 30km an hour but i could be wrong. There are lots of places to look that up on the internet. Wikipedia has a fairly good article on wind power. If the wind is going too fast, the often shut down the turbines because they are built to withstand a certain pressure. If the wind is too high (which sometimes happens in Southern Alberta, Canada), they risk destroying the turbines. Watts are a measure of electrical power, not wind power.

A windmill (wind pump) is a structure or machine that converts wind into usable energy through the rotation of a wheel made up of adjustable blades.

Wind is used to turn the blades of a turbine, which spins a generator to produce electricity. As the blades turn, the generator converts the mechanical energy from the wind into electrical energy through electromagnetic induction. This electricity is then sent through transmission lines to power homes and businesses.

No, a fan does not convert electricity into wind energy. The electricity powers the motor in the fan, which then rotates the blades to create airflow or wind. The wind energy is not converted into electricity.

Winds generally blow from areas of high pressure to areas of low pressure. However, local factors such as topography, temperature gradients, and proximity to large bodies of water can influence wind direction as well.

1. Wind is the movement of air from high pressure areas to low pressure areas.
2. Winds are caused by the uneven heating of Earth's surface by the sun.
3. Wind can be harnessed as a source of renewable energy through wind turbines.

-- coal burns in oxygen

-- burning releases heat

-- heat is used to boil water

-- steam from boiling water is guided through the fan of a turbine

-- pressure of the steam through the fan turns the turbine

-- turbine turns an electric generator

-- if you're lucky, maybe 35% of the energy in the coal comes out as usable electrical energy.

The rest makes all the equipment hot, and eventually seeps off into the atmosphere.

Wind possesses kinetic energy, which is the energy of motion. As wind blows, it carries kinetic energy that can be harnessed to generate electricity through wind turbines.

The least amount of wind in the country is typically found in areas that are shielded by geographical features such as mountains or forests, or regions that are located far inland and away from coastlines where sea breezes are common. Areas with consistent high-pressure systems can also experience lower wind speeds. Some examples include parts of the Great Plains in the United States or inland valleys in regions like the Midwest or the central United Kingdom.

Fossil fuels are made from the remains of ancient organisms like plants and animals that have been buried for millions of years. This organic matter gets transformed into fuels like coal, oil, and natural gas through heat and pressure underground. Their formation process over such a long timescale is what makes them known as fossil fuels.

Wind power is useful because it is a renewable energy source that produces electricity without emitting greenhouse gases or other pollutants. It helps reduce reliance on fossil fuels, contributes to energy security, and can help mitigate the effects of climate change.

Opinions on wind energy vary. Some people view it as a clean and sustainable alternative to fossil fuels, contributing to lower greenhouse gas emissions. Others have concerns about its visual impact on landscapes, noise levels, and potential harm to wildlife.

Wind power technology has improved significantly over time, leading to more efficient turbines with higher energy output. Innovations in design, blade materials, and control systems have made wind power a more reliable and cost-effective source of renewable energy. As a result, wind power capacity has grown rapidly worldwide, becoming a key player in the transition to clean energy.

Wind power is often considered better than biomass because it is a renewable energy source that does not produce greenhouse gas emissions during electricity generation. Wind power also has a lower environmental impact compared to biomass, which can involve land use changes, emissions from transportation of biomass feedstock, and air pollution from combustion. Additionally, wind power is more cost-effective and has lower operating and maintenance expenses compared to biomass energy.

Wind turbines blades are about 15 meters long (average wind turbine)

The thickness of the blade depends on the length of the blade. The width is about 10% of the length, in this case, would be about 1.5 meters thick.

it is dependent on weather conditions, making it unpredictable and intermittent. This can lead to fluctuations in electricity generation and can require backup power sources to maintain a consistent supply.

The measurements of a windmill can vary depending on the size and design. The typical height of a windmill can range from 20 to 80 meters tall, with rotor diameters ranging from 50 to 120 meters. The size of the tower, blades, and overall structure will depend on the power output and location of the windmill.

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.

Technically YES... the wind forces the turbine blades to spin a rod inside that moves a magnet in and out of a copper coil that generates the flow of electron. The wind that you feel is movement of gases that make our atmosphere (Nitrogen, Oxygen etc) on a very large scale. Globally, the two major driving factors of large-scale winds (the atmospheric circulation) are (a) the differential heating between the equator and the poles (difference in absorption of solar energy leading to buoyancy forces) and (b) the rotation of the planet. Both of the reasons why we have wind on Earth are technically due to the Sun. Nuclear energy plants utilize energy from material that was created in a supernova before the birth of our solar system.

The wind turns a windmill which then turns a turbine that generates electricity using inductance. Also, more 'primitive' applications simply use a windmill to turn gears and shafts to pump water or grind grain, etc.

The minimum wind speed of a gale is typically defined as sustained winds of 34 to 40 knots (39 to 46 mph or 63 to 74 km/h). It can vary slightly depending on the source and classification system used.
