Energy Sources Explained Part 03: Wind Power

What is Wind Power?

Wind power is the power produced by moving air which is caused by the differences in atmospheric pressure. Speed of wind vary based on topography season and geography. So there are locations suited for energy generation and locations not suited.

Locations

Best locations for wind energy generation are most of the time close to the sea but high enough, or offshore.

How does it work?

If the blowing wind is able to turn the blades, we will receive electricity from the generator that is attached to it. A closer look at the blade shows that it has a lot of airfoil cross-sections consisting of different sizes and shapes from root to tip. These basic airfoil tech makes the blades turn. The blades use to be positioned in a tilted manner in order to align with the relative wind speed. The blades are attached to a gearbox which is there because our rotation is still low-speed. The gearbox is attached to the generator which is transferred through cables to the base of the wind turbine where a step-up transformer is situated.

History of wind power

Through the eons our civilization have used this energy for reasons like pumping water or milling grain.

Advantages of wind energy production

The major advantage of wind power is that the production of electricity has no direct CO2 emissions. Secondary advantages are that wind power is inexhaustible, it doesn't use water unlike conventional electricity sources and wind power is cost-effective.

Disadvantages of wind energy production

As you might have guessed wind does not blow all the time and fluctuate each day. It might be cost-effective as production but it involves high upfront capital investment. Some authorities believe that there are noise disturbances that might reduce the local fauna (newer models are better and produce less noise).
