Engineering Technology Division Power Plant Construction and QA/QC Section 1.8– Wind Energy

2 Development Limitations Environmental Aspects
Section 1.8– Wind Energy Overview Definition Generation History Benefits Resources Effect on Height Development Limitations Environmental Aspects

3 Section 1.8– Wind Energy Definition Wind is the flow of gases or air on a large scale. In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet.

4 Differential Heating / Cooling
Section 1.8– Wind Energy Generation High to Low Pressure Differential Heating / Cooling “Coriolis Effect”

5 Section 1.8– Wind Energy History

6 Does not contribute to global warming
Section 1.8– Wind Energy Benefits Wind energy Releases no pollution Does not contribute to global warming Wind power is a free and inexhaustible ("renewable") Diversifies the national energy portfolio Reduces reliance on imported fuels wind turbines do not consume water. Drawback Inconsistent (supplemental only)

7 Section 1.8– Wind Energy Benefits - Emissions

8 Section 1.8– Wind Energy Resources

9 Turbulent versus Laminar Flow
Section 1.8– Wind Energy Effect on Height Turbulent versus Laminar Flow

10 Section 1.8– Wind Energy Development - Types

11 Development - Limitations
Section 1.8– Wind Energy Development - Limitations Winds unreliability factor. Wind turbines generally produce allot less electricity. Wind turbine construction can be very expensive. Costly to surrounding wildlife. The noise pollution is sometimes similar to a small jet engine. Protests and/or petitions usually confront any proposed wind farm development.

12 Wind Farm Land Usage – Large tracts required
Section 1.8– Wind Energy Environmental Aspects Wind Farm Land Usage – Large tracts required Construction – underground habitats Birds and Bats – noise and blade movement Noise Pollution – wind speed and distance Visual Impact – man-made versus natural

13 Section 1.8– Wind Energy Questions?
