Transcript of wind power

environmental impact onshore wind farm group of wind turbines in the same area
onshore offshore http://de.wikipedia.org/wiki/Windpark
http://www.evwind.es/wp-uploads/2012/07/offshoregrande.jpg general •advantage
easier to implement
less expensive
lower yield
•installed on ridgelines three kilometres from the nearest shoreline
•minimum distance between each turbine
prevailing wind direction: five times the rotor diameter
addition to wind direction: triple rotor diameter
•for optimum efficiency: distance of 15 times the rotor diameter conversion of wind energy into a useful form of energy

- wind turbines
- windmills
- wind pumps
- sails http://en.wikipedia.org/wiki/Wind_farm
http://de.wikipedia.org/wiki/Windpark assets and drawbacks examples •first wind farm in New Hampshire
in 1980
20 wind turbines of 30 kilowatt
total of 0,6 MW •largest in Europa in Romania
in 2012
240 turbines
total of 600 MW •largest wind farm in India
in 2001
total of 1064 MW + alternative to fossil fuels
+ plentiful
+ renewable
+ clean
+ widely distributed
+ produces no greenhouse gas
+ uses little land

- dependent on the weather
- higher construction costs

- also higher energy costs facts http://en.wikipedia.org/wiki/Wind_farm
http://en.wikipedia.org/wiki/F%C3%A2nt%C3%A2nele-Cogealac_Wind_Farm http://gizmodo.com/5675719/the-best-of-green-tech-wind-turbines
http://en.wikipedia.org/wiki/File:F%C3%A2nt%C3%A2nele-Cogealac_Wind_Farm_2011.jpg 83 countries using wind power

2010: production was over 2.5%
of total worldwide electricity usage

growing rapidly

international collaboration wind energy offshore the construction of wind farms in bodies of water
better wind speeds available
so offshore wind power output is higher
However, offshore wind farms are relatively expensive. http://www.flickr.com/photos/gcook/2553467373/sizes/l/in/photostream/ http://www.flickr.com/photos/karelh/5170147530/sizes/l/in/photostream/ http://en.wikipedia.org/wiki/Offshore_wind_power wind farms followed by the Walney Wind Farm at 367 MW, also in the UK http://en.wikipedia.org/wiki/Offshore_wind_power
http://www.power-technology.com/projects/greatergabbardoffsho/images/1-image-1.jpg the Greater Gabbard Wind Farm is the largest offshore wind farm in the world at 504 MW Martin Allinger

Felix Mach environmental impact is relatively
low compared to the impact of
traditional energy sources
- vegetation clearing for wind farms is minimal
- farmers lease their land to companies building wind farms
- only 1% of land is used for wind farms
- affecting wildlife (birds, bats,…)
aesthetics: subjective - some people like them
and some don’t http://en.wikipedia.org/wiki/Environmental_impact_of_wind_power http://en.wikipedia.org/wiki/Environmental_impact_of_wind_power ecology environmental impact impacts on people noise: modern wind turbines produce
less noise than older ones shadow and noise for nearby residences video - wind turbine construction by 2020, offshore wind power capacity is expected to reach a total of 75 GW worldwide www.youtube.com/watch?v=DxOYwWu7Xcc
