Taking you back to high school shop class, here's how to make your own wind turbine blades out of wood. The wood base easily picked up at any home building store (or heck, from fallen trees in the nearby forest), wood turbines are a more affordable option for a do-it-yourselfer as you can measure and handle the wood before you purchase and begin cutting.
Wind power is seen as one of the renewable energy sources that can be tapped to decrease the greenhouse gas in the atmosphere. At present, it is used across the world, with some countries getting ten percent of their power from it.
Let us take a break from all the DIY projects for now and learn of the story of a teenager from Malawi, who harnessed the power of the wind by building windmills out of junk. At present, William Kamkwamba has high-profile fans, such as Al Gore and other business leaders, all over the world.
