Introduction

In the last decade, we have heard more and more about the need of renewable clean energy, but not much has been done. Today, pollution and greenhouse gases are at its peak all over the world and the price of oil is higher than ever. Our earth is getting very sick, and it is time that we start contributing in fighting pollution by exploiting renewable clean energy. These clean energy consist of solar energy, wind power, geothermal heat, hydroelectricity, biofuels, and more. Currently, the wind power energy is the most popular of all of these green technologies. Thousands of wind turbines are being invested and installed everywhere worldwide. Thus, many questions arise. What is a wind turbine? What are the different types of design? What are the advantages and disadvantages? How do the aerodynamic blades work? Are these wind turbines worth investing? Is it feasible? Will they help us significantly in reducing greenhouse gases? And what are impacts of wind turbine in our environment? These are the questions that I will attempt to answer.
