1. Wind Energy Mohammad Farooq, Khayyam Saleem, Evan Keating

2. ● Wind energy -> Mechanical Energy -> Electrical Energy ● Generator used to convert mechanical energy into electrical energy How Wind Power is Generated

4. ● Characterized by wind power density classes o 1-7, 7 being the highest ● Good wind resources: 3 or higher ● Energy derived proportional to square of wind speed Resources of Wind Energy (US)

6. Industrial => Every state => Farms Utilities => States with open space Consumer => Little to none ($$$) Target Market

7. ● Free, renewable source ● Clean, non-polluting electricity production o 1990 - California’s wind production offset emission of carbon by >2.5B pounds ● Sustainable Advantages of Wind Power

8. ● Domestic source of energy o Reduces dependence on foreign countries ● Turbines can be built on existing farms and ranches Advantages of Wind Power

9. ● Good wind sites usually located far from where power is needed ● Turbines may not be the most profitable use of land Disadvantages of Wind Power

10. ● Noise and aesthetic pollution ● Turbines may damage local wildlife/ upset ecosystem o Birds fly into wind turbines ● Wind can not be predicted Disadvantages of Wind Power

11. ● Available space for turbines often distant from major cities and power plants ● Wind not consistent in most areas ● Technology still developing ● More expensive than cheap fossil fuels Roadblocks

12. ● US taxpayers paying extra $8.5-$10 billion per year for wind energy ● Only generates 3.5% of electricity Expenses

14. Expenses

16. Total Initial Cost/(Annual Energy Cost Savings – Annual Operating Costs) = Payback time, in years ---------------------------------------------------------------------------- Residential 5 kW system = $15,000 Residential $0.06/kWh x 10,000 kWh = $600 Residential $0.01/kWh x 10,000 kWh = $100 ---------------------------------------------------------------------------- $15,000/($600 – $100) = $15,000/$500 = 30 years Payback Period for Deployment
