Wind Energy

By Evan Ruderman

what is it
What is it?
  • Conversion of wind energy into a useful form of electricity
  • Over past 5 years installations have grown by 27.6%
  • Currently generates 2.5% of world’s needed energy
  • Will be able to generate 3.35% by 2013
  • Should be able to generate 8% by 2018
can be utilized greatly
Can be utilized greatly:
  • Denmark- 21%
  • Portugal- 18%
  • Spain- 16%
  • Ireland- 14%
  • Germany- 9%
types of wind energy
Types of Wind Energy
  • Sail- propel a ship
  • Windmills- mechanical energy
  • Wind pumps- pumping or draining water
  • Wind turbines- make electricity (wind farms- 100s of wind turbines)
history
History
  • Has been used to propel boats for over 5,500 years
  • Began to be used to power irrigation pumps in 7th century
  • 1887- UK began experimenting with wind power, the US began to experiment with it too
  • January 1888- Charles F. Brush harvested electricity, powered his house and lab with it
  • 1970’s NASA started testing, developed many modern features of the wind turbine
  • Modern turbine industry started in 1979 by Danish Manufacturers

First wind farm in US was on Crotched Mountain

offshore wind energy
Offshore Wind Energy
  • Wind farms can be built offshore
  • Offshore offers better wind speeds
  • Some people complain it ruins coastline
downsides
Downsides
  • Visual impairment
  • Noise (nearby)
  • Sometimes need to clear land
  • Sometimes need to build roads
  • Can be unpredictable
overall
Overall

Pros

Cons

Can visually impair

Sometimes land needs to be cleared

Can be unpredictable

  • Alternative to fossil fuels
  • Renewable
  • Can be used on or offshore
  • Very clean
  • No green house gases produced
  • About same price as coal or natural oil
  • Uses little land
