3. SECTION 1: SUMMARY Wind power is electricity made by wind turning a turbine. In this PowerPoint, I will explain the history of wind power generation, how wind energy is made, it's pros and cons, Examples of wind generation and the total cost of the turbines.

4. SECTION 2: HISTORY OF WIND GENERATION During July 1887 a Scottish academic built a wind turbine in his backyard to power his cottage. He used that source of energy until the 1900s to power his laboratory and house. In the mid 1920s companies started making wind turbines and sold them to people. They were extremely popular but were rendered obsolete due to large demands of electricity. In 1931 a French engineer made a horizontal axis turbine. In 1956 a former student of La Court built a 3 bladed turbine that influenced many designs of turbines.

5. SECTION 3: HOW WIND ENERGY IS GENERATED Wind energy is generated by moving metal through a magnetic field. This movement is generated by the wind turning the turbines.

6. Renewable Clean Reduced Greenhouse Gas Emissions Reduced fossil fuels used Abundant supply Sustainable PROS

7. Wind is inconsistent, unsteady, unpredictable The wind turbines aren’t cheap Visual pollution Loud About 20,000 birds die annually Impact on weather locally CONS

8. EXAMPLES

10. Commercial-scale wind turbines normally cost 1.3-2.2 million dollars per 1 megawatt of storage. Most wind turbines have 2 megawatts of storage, and cost 3-4 million dollars. There are also other aspects like tax and other incentives that could majorly decrease the price. COST
