Denmark aims to run 100% on wind energy by 2050


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 inhabitants on the planet increases 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 with the help of 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

Fact 1. 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.

Fact 2. 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.

Fact 3. 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.

Fact 4. 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.

Fact 5. A wind turbine rotates with a speed of 15 to 20 RPM (revolutions per minute) while generating clean electricity.

Fact 6. A wind turbine rotates 70 to 80% of the time and produces clean electricity all this time.

Fact 7. A wind turbine requires less than 1 acre of land to install the turbine and the transmission substation used to send the power into the grid.

Fact 8. The land that hosts the wind turbine and the substation can still be used for farming.

Fact 9. 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.

Fact 10. A large wind turbine can generate enough energy to power a number of 1,220 households.

Fact 11. The same large wind turbine can displace a number of 16,000 medium-sized solar panels in terms of clean electricity generation.

Fact 12. After the installation, the wind turbine will have low operational costs and will produce clean electricity for about 25 years.

Fact 13. The energy consumed during the construction of the wind turbine will be produced by the turbine in the first six months of operation.

Fact 14. A large wind turbine will displace about 2,350 tonnes of CO2 per year.

Fact 15. Coal, gas and nuclear energy consume water to produce electricity, but a wind turbine operates without consuming water.

Fact 16. A large wind turbine can save about 14 million gallons of water during one year of functioning.

Fact 17. Wind turbines kill a small number of birds and bats every year, but the number of bird fatalities is smaller than the number of birds killed by cars, cats, power lines or buildings per year.

Fact 18. 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.

Fact 19. Onshore wind has become today the cheapest form of renewable energy, and could become even cheaper than natural gas in the future.

Fact 20. The world governments provide subsidies for wind energy in order to promote a wide spread of this form of clean power.

Fact 21. In some European countries such as Denmark, wind energy has become cheaper than the energy produced by fossil fuels.

Fact 22. Wind turbines work well in offshore because there are no natural obstacles to block the wind.

Fact 23. Wind power can reduce the dependence on foreign fossil fuels.

Fact 24. 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.

Fact 25. 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.

Fact 26. The largest onshore wind turbine in the world generates 4.8 MW and has a height of 787 feet (240 meters) and a propeller with the diameter of 158 meters.

The turbine is produced by GE Renewable Energy and will produce energy that can power a number of 5,000 European residential homes.

Fact 27. 5.5% of the energy produced in the U.S. is generated by wind power, and this percent is set to increase at 20% by 2030.

Fact 28. 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.

Fact 29. 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.

Fact 30. 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.

Fact 31. Wind power works well along with the conventional sources of energy and can lower the consumption of dirty energy (produced by fossil fuels).

Fact 32. In the near future, the floating wind turbines that will harness the wind power at high altitudes will become available on a large scale.

Fact 33. Coastal countries have a great potential for wind power because the wind is stronger there due to the proximity of the ocean.

Fact 34. Texas has the highest capacity of wind power installed in the U.S. with an output of 20,000 MW (20 GW).

Fact 35. The U.S. state that generates the highest amount of electricity from wind power in its energy mix is Iowa.

Fact 36. California is hosting the largest wind farm in the United States (Alta Wind Energy Center, which is also known as Mojave Wind Farm), with an output of 1548 MW.

Fact 37. Nebraska is the eighteenth U.S. state that has started to harness the power of the wind and today has an installed capacity of 1,000 MW.

Fact 38. Roscoe Wind Farm located in Roscoe, Texas, is the largest wind farm in Texas with a number of 627 wind turbines and an output of 781.5 MW.

The second largest wind farm in Texas is Horse Hollow Wind Energy Center with an output of 735.5 MW.

Fact 39. The EU is more advanced in wind power generation and today has an installed capacity of 160 GW.

Fact 40. Estimates say that the EU will have an installed capacity of wind power of 323 GW in 2030, from which 253 GW onshore and 70 GW offshore.

Wind is a clean and free energy source provided by the Sun, and we need to harness all the wind energy capacity of the planet to reduce the use of fossil fuels for a cleaner future.

    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?
