The interest in renewable energy has increased greatly. The US currently produces enough wind energy to power 14 million homes. Approximately 2% of our energy comes from wnd, which is double from just 3 years ago. many beleive that in 2030, 15-20% of our energy will come from wind.
The reason for the growth is partially associated with new government regulations concerning our impact on the environment. Federal and local governments are receiving pressure from voters to find alternative sources. Experts believe that if the 2030 scenerio occurs, we would reduce carbon dioxide emissions by 7600 metric tons and create 200,000 jobs.
Windmills have been around for centuries to pump water and grind seeds into grain. A wind turbine is an advancement that turns an electrical generator. The force of the wind, turns the blades. the rotor turns and spins a driveshaft that is connected to an generator. the generator converts this mechanical energy in to electrical energy.
There are several variables that determine the amount of energy produced: wind speed, diameter of the rotor, density of the air, and efficiency of the turbine.
A great product for teaching wind power concepts is the Basic Turbine. The Basic Turbine is a great start for teaching about wind energy in the classroom. Visit www.heathscientific.net to purchase this item. This is the most affordable and robust wind turbine kit on the market. Design blades and test your power output with a multimeter, LED bulbs, or an ultra capacitor.
The instructions that are included will show you how to build this PVC turbine, how to make blades for your wind turbine, how to use a multimeter to record electrical data and will discuss some basic wind energy science.
