40 Wind Energy And Wind Turbine Facts

wind energy facts

The power of the wind is harnessed by mankind for thousands of years and was first used for transportation (on sea and land), for agriculture, and lately, to produce clean energy that can power homes and companies.

The energy demand increases from one year to another due to the fact that the number of people living on the planet continues to grow and because the fossil fuels used to produce energy are becoming more expensive, we need to use alternative energy sources such as wind energy to create an additional source of power that can meet the growing energy demand.

What is Wind Energy?

Wind energy is considered one the best and cleanest sources of renewable energy available on the planet today.

Wind energy is harnessed today both offshore and onshore with the help of large wind turbines that are converting the kinetic energy of the wind into clean electricity with the help of generators.

Wind is considered a renewable energy source because is produced by the Sun by heating the different layers of the atmosphere in an uneven way.

Wind energy is considered a clean and alternative energy source because is produced by the Sun every day and the wind turbine that converts the kinetic force of the wind into clean electricity are releasing no harmful emissions in the atmosphere.

Facts About Wind Energy And Wind Turbines

Wind Energy is a renewable energy sector in continuous development.

Wind Is An Ancient Source Of Power For Mankind

The power of the wind has been used by mankind starting with 2000 B.C. when the ancient sailors from Persia and China used the wind to sail with their ships.

Farmers have used windmills to grind grains and pump water.

Wind Energy Has Many Uses

Wind power can be used in many ways, such as: to sail with sailboats, in farming activities that require a windmill (grinding grain, pumping water, etc.) and to produce clean electricity using a horizontal or a vertical wind turbine.

Wind Has A Great Potential To Generate Green Power

Wind energy has a huge potential to generate clean electricity, but today we are harnessing only a very small percentage of this potential on land and sea.

Wind Is An Energy Source Of The Future

Wind power increases its presence in the energy mix of many countries of the world, but we need to wait a few more decades until wind power will replace the fossil fuels as a main energy source in the world’s energy mix.

Wind Turbines Start Generating Power At Low Rotational Speeds

A wind turbine starts generating clean electricity when the wind has a speed of at least 7 mph (11 km/h).
The nominal output of the turbine is reached at a rotational speed of 15 to 20 RPM (revolutions per minute).

Wind Turbines Can Produce Power Day And Night

A wind turbine rotates 70 to 80% of the time and produces clean electricity all this time.

A Large Wind Turbines Requires A Small Area Of Land

A wind turbine requires less than 1 acre of land to install the turbine and the transmission substation used to send power into the grid.

The Land Used By A Wind Turbine Can Other Other Uses As Well

The land hosting a wind turbine and the substation attached, can still be used for farming.

Wind Power Is Generated In Open Areas

A wind turbine can work properly on a land that has no natural or artificial obstacles such as mountains, hills, tall forests or buildings.

Without these obstacles the wind can fly freely, so the turbine will be able to generate huge amounts of clean electricity day and night.

A Large Wind Turbine Can Power Itself Hundreds Of Homes

A large wind turbine can generate enough energy to power hundreds of households during the days with good winds.

A Large Wind Turbine Can Displace Thousands Of Solar Panels

A large wind turbine can displace a number of 16,000 medium-sized solar panels in terms of clean electricity generation.

Wind Turbines Have Low Operational Costs

After the installation, a wind turbine has low operational and maintenance costs, and will produce clean electricity for about 25 years.

A Wind Turbine Can Recover The Energy Consumed During Its Manufacturing Process Quickly

The energy consumed during the construction of a wind turbine will be produced by the turbine in the first six months of operation.

Wind Turbines Reduce Air Pollution

A large wind turbine will displace about 2,350 tonnes of CO2 every year.

Wind Turbines Do Not Consume Water To Generate Power

Coal, gas and nuclear energy consume water to produce electricity, but a wind turbine operates without consuming water.

Wind Turbines Save A Large Volume Of Water Every Year

A large wind turbine can save about 14 million gallons of water during one year of functioning.

Wind Turbines Do Kill Some Birds And Bats Every Year

Wind turbines kill a small number of birds and bats every year, but the number of bird fatalities produced by wind turbines is way smaller than the number of birds killed by cars, cats, power lines and buildings every year.

Modern Wind Turbines Are Less Noisy

A modern wind turbine is quieter than the previous models because the sound heard at a distance of 400 meters from the turbine is only 40 db(A) (A-weighted decibels), which is similar to the sound produced by a fridge.

Onshore Wind Is The Cheapest Source Of Electricity

Onshore wind has become today the cheapest form of renewable energy, and could become even cheaper than natural gas in the future.

Governmental Subsidies Promote Wind Power

The world governments provide subsidies for wind energy in order to promote a wide spread of this form of clean power.

In the EU Wind Turbines Produce Very Cheap Electricity

In some European countries such as Denmark, wind energy has become cheaper than the energy produced by fossil fuels.

Offshore Wind Has A Great Potential

Wind turbines work well in offshore because there are no natural obstacles to block the wind.

Wind Power Reduces Our Dependence On Fossil Fuels

Wind power can reduce the dependence on foreign fossil fuels.

Europe Started Early To Produce Electricity Using Wind Power

Europe is a world leader in offshore wind power and started to use this form of renewable energy almost three decades ago (the first offshore wind farm was installed in Denmark in 1991).

The first offshore wind farm in the U.S. (Block Island Wind Farm uses 5 turbines with an output of 30 MW) was commissioned in December 2016.

Denmark Has The Lagest Offshore Wind Turbine

The largest offshore wind turbine in the world is installed in Denmark and has a height of 722 feet (220 meters) and 80 meters-long blades.

Vestas V164 Is The Largest Onshore Wind Turbine In The World

The largest onshore wind turbine in the world generates 9.5 MW and has a height of 722 ft (220 m), and a diameter of 538 ft (164 m).

The largest offshore wind turbine in the world is Heliade-X 12 MW that has a height of 853 ft (260 m) and the rotor has a diameter of 722 ft (22 m).

These turbines are built by GE Renewable Energy and each one produces energy that powers a number of 16,000 European residential homes.

The Share Of Wind Power In The Energy Mix Of the U.S. Continues To Grow

7% of the total energy produced in the U.S. was generated by wind power in 2019, and this percent is set to increase at 20% by 2030.

Wind Power Can Be Produced Day And Night

Solar energy works well only during the sunny days, but wind power can work both during the day and the night if there is wind that can spin the blades.

Nearly 60% Of Americans Consider Wind Power An Alternative Energy Source

Today, more than 6 out of 10 people agree that wind energy must be further developed in order to reduce our dependence on fossil fuels.

The percentage of people supporting the further development of the wind energy sector will increase to 80% in the next decade.

Wind Turbines Are More Affordable Every Year

The advances in technology and the increased production of wind turbines in the world lowers the initial costs of the turbines, which makes wind power more affordable to a larger number of clients.

    Thanks Magda,

    I’m really getting more and more interested in setting up a personal wind energy system to support my solar energy system! Do you have an article on how an individual can go about that with estimated costs?
