Engineering Technology Division Power Plant Construction and QA/QC Section 1.8– Wind Energy
Section 1.8– Wind Energy Overview • Definition • Generation • History • Benefits • Resources • Effect on Height • Development Limitations • Environmental Aspects
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.

Section 1.8– Wind Energy History
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)

Section 1.8– Wind Energy Development - Types
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.
