Wind Power

 Freeway Wind Power

With the Republicans kicking and screaming as they are dragged along, it seems like the Untied States is finally trying to make some forward progress in alternative energies. The desire to live off the grid has exploded and everyone is wanting to become a part of the trendy new solution to world destruction and fossil-fuel dependency. Many Americans now see that these new technologies not only shrink their environmental footprint but also saves them some cold hard cash in the process. This revelation has brought green living many new converts over the last several years, but without widespread cooperation from the private, corporate, and federal level, change may be too slow to come. Let’s face it, we can’t just wait around until everyone has the money to buy an electric car and put solar panels on their roof. Perhaps it is time to start exploiting some of the United States unnatural, renewable resources.

One must look no further than the daily commute to work to discover one of our nation’s greatest, untapped resources. According to the Federal Highway Administration, the United States currently has over 45,000 miles of interstate highways hosting millions of travelers each day. Besides the countless tons of pollutants being spilled out of these vehicles’ collective tail pipes, the freeway traffic has one other commonly created resource; wind turbulence. As these vehicles barrel down our nation’

This s highways, at nearly 70 mph, they displace the air around them causing air currents that could be harnessed by wind turbines located in the medians. Our roads could one day be lined with millions of these small, vertical-axis wind turbines turning what is currently a black stain on environmentalism into a serious hope for the future. nearly free, clean energy could be a major factor in easing the national dependency on fossil fuels as well as power millions of homes and businesses around the country.

Advantages of Wind Energy

Wind power actually works a lot like hydroelectric power. Both of them simply require a driving force that creates kinetic energy. With hydroelectricity, it’s water that creates a driving force. With a wind generator, or turbine, wind is the driving force.

A wind generator consists of three basic parts:

  • Rotor blades: Rotor blades transfer energy from the wind and turn it into kinetic energy.
  • Shaft: When the rotor blades rotate, they turn the shaft, which transfers mechanical energy into the generator.
  • Generator: Generators utilize the principle of electromagnetic induction. When the magnets are rotated around a conductor, they generate electricity.

Wind generators are really that simple. Electricity is generated by magnets rotating around an electrical coil.

The power of the wind is used to rotate the magnetic field around the coil, and this causes the atoms and electrons to be displaced. Kinetic energy is created, and this energy is then turned into electricity.

When you’re trying to calculate the cost-effectiveness of a wind turbine, you must consider two things: energy costs and wind speed. The basic rule of thumb is that the average wind speed in your area should be be at least 10 mph. If finances are a concern, wind turbines begin to make economic sense at about 10 cents per kilowatt hour.

Today, wind turbines are becoming more economical to produce, as well as more and more efficient all the time. You can expect to see wind turbines powering rural homes and being used more often in windy areas – even turbines used in the ocean will soon become a common occurrence.
