Informations and news about wind turbines
We know about turbines something less or more but have you ever think about how big wind turbines can be? Norway has announced plans to build the world’s largest wind turbine. The turbine will measure 533 feet high with a rotor diameter of 475 feet. With that big size will also come big power – the turbine is expected to…
Another type of turbine developed at about the same time as the Darrieus was the Savonius turbine, developed in Finland by S. J. Savonius. This is anothervertical axis machine which needs no orientation into the wind. Alternative energy enthusiasts often build this turbine from used oil barrels by cutting the barrels in half lengthwise and welding the two halves back together offset from…
The Darrieus wind turbines was patented in the United States by G. J. M. Darrieus in 1931. It was reinvented by engineers with the National Research Council of Canada in the early 1970’s. Sandia Laboratories built a 5 m diameter Darrieus in 1974, and has been strongly involved with further research on the Darrieus turbine since that time.…
Horizontal-axis wind turbines (HAWT) have the main rotor shaft and electrical generator at the top of a tower, and may be pointed into or out of the wind. Small turbines are pointed by a simple wind vane, while large turbines generally use a wind sensor coupled with a servo motor. Most have a gearbox, which turns the…
We know that there is enough wind globally to satisfy much, or even most, of humanity’s energy requirements – if it could be harvested effectively and on a large enough scale. Vertical axis wind turbines (VAWTs), which may be as efficient as current horizontal axis systems, might be , simpler and significantly cheaper to build and maintain…
The wind energy sector is experiencing significant growth, with global installed capacity projected to surpass 300 gigawatts (GW) by the end of 2023. This translates to generating enough clean energy to power 114 nuclear power plants, a significant milestone in the global transition towards renewable energy sources. Key Statistics: 300 GW: Global wind power capacity expected…
There are two types of wind turbines. One is Vertical axis wind turbines and the other is horizontal axis wind turbines. We know that there is enough wind globally to satisfy much, or even most, of humanity’s energy requirements – if it could be harvested effectively and on a large enough scale. Vertical Axis Wind Turbines Vertical axis wind turbines(VAWTs), which may be…
What is Wind? Wind is simply air in motion. It is caused by the uneven heating of the earth’s surface by radiant energy from the sun. Since the earth’s surface is made of very different types of land and water, it absorbs the sun’s energy at different rates. Water usually does not heat or cool as quickly…
Wind energy is one of the more efficient alternatives to fossil fuel energy. Wind power gives a significant Return On Investment (ROI) since it’s free energy that also has an endless renewable power source. 59% efficiency is the BEST a conventional wind turbine can do in extracting power from the wind. Wind Power depends on: • amount of air (volume)• speed…
