Plusses and Minuses of Wind Energy - Wilkes University

Plusses and Minuses of Wind Energy By Haoxiang Wang, Alec Bolinsky, Rhiannon (Annie) Stauffer, Abdullah Harkan Prepared for BIO / EES / EGY 105 at Wilkes University, 11 December 2015 Introduction to Wind Energy - History Proof of wind energy use as early as 5000 B.C.

By 200 B.C., simple windmills were used in China Vertical-axis windmills used in Persia and the Middle East

By the 11th century, Middle East used windmills extensively for food production a. Idea was also brought to Europe by merchants and crusaders The Dutch refined the windmill

a. Settlers took windmills to the New World in the late 19th century Wind Energy History Development of electric power - windmills used in 20th century

Interest in wind power became greater during oil shortages in 1970s Wind energy in the US waned during 1980s

Continued to grow in Europe Wind Energy Today Wind energy is now considered fastest growing energy source in the world Wind-powered generators in operation in every size range

Currently produces more than 10% of electricity in 9 states Wind Energy Growth How a Wind Turbine Works Pros & Cons of Wind Energy

1 .U.S. emissions have primarily come from power sector a.38% Nation-wide emission b.Coal = 70% of power sector emissions. c.Natural Gas= 20% of power sector emissions 2. Potential for wind energy is extraordinary a.Can supply an estimated 20% of U.S. and world electricity b.Currently only accounts for 4% of the power sector Future of Wind Energy

Wind Vision Report Wind energy can become one of Americas top electricity sources by mid-century a.

10% by 2020 b. 20% by 2030 c. 35% by 2050

Will deliver tens of billions of dollars of savings per year Wind power positives outweigh the negatives Any negative impact of wind power has a solution

We must promote wind power renewable energy economy Wind can provide a sustainable energy for the future
