Extrinsic hemolytic anemia is also known as autoimmune hemolytic anemia. This type of anemia develops when the spleen traps and destroys healthy red blood cells. Intrinsic hemolytic anemia develops when the red blood cells produced by your body are defective.

Today, the windmill's modern equivalent-a wind turbine-can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.
Learn how long humans have been using windmills, how big wind turbines can be, how much of the worldâs electricity is generated from wind power and much more. Wind power involves turning energy from the wind into other forms of useful energy. Wind power can be harnessed in a number of different ways.For example, windmills create mechanical energy, sails move boats and wind turbines generate electricity.Windmills have been around for a long time, they were used in Persia (Iran) as far back as 200 B.C. Wind energy is clean and renewable.Large groups of wind turbines are called wind farms. Around 80 different countries use wind power to generate electricity commercially (as of 2009). In 1997 wind power generated only 0.1% of the worldâs electricity, this increased to 1.5% in 2008 and 2.5% in 2010.ind energy is clean and renewable.
