WIND Energy Neel Sangal Joey Trinity Stefani Spence
How wind works! • Turbines transform mechanical energy to electrical energy. • Wind • Turbines • http://www.youtube.com/watch?v=0Kx3qj_oRCc&feature=related
Wind Usage • All around the world! 5,112MW 40,000MW 42,000MW 27,214MW
Positive Benefits • Reduced CO2, SO2 outputs. • Reduced use of nonrenewable energy • The energy needed to build turbines is quickly recovered • Wind power uses less land
Negative Consequences • Difficult to connect many wind turbines to get the energy out of the • Property values decrease where wind farms are visible. • Hurts tourism • Kills bats
How efficient would this resource be? • An individual windmill can produce around 60-75 kW • In California, a wind farm of 17,000 windmills produces 1400MW (80% of US wind capacity) • In 1998 wind farms produced enough electricity to power San Francisco • Wind energy = 2nd least expensive source in CA
Continued • It is estimated that there is enough wind energy in Texas and the Dakotas for the entire US • Wind currently supplies less than 1% of the world’s electricity, but could supply 10% and eventually surpass the #1 source (hydropower – 20%)
Where is the ideal location in the US? • The coastal Northeast • Belt from Texas to the Rockies and the Dakotas • Mountains in North Carolina/northern Coachella Valley (CA) • Good site has sustained wind velocity of 5 m/sec • Wind velocity increases over hilltops and through mountain passes • Where land is unavailable, turbines can be sited offshore
Is it available in our community? • On the individual level: • Bethlehem and Lebanon Townships are drafting ordinances to regulate individually-owned wind turbines • Wind energy had been added to the list of things with “inherently beneficial use” along with hospitals, schools, etc
Is it available in our state? • New Jersey’s goal = generate 200MW from wind turbines by 2020 (currently 3MW) • In 2008 Corzine drafted energy plan that would provide for 1000MW of offshore wind by 2020 as well as a wind farm that would be operable by 2013
What is the cost? • 1 state-of-the-art commercial turbine totals about $700,000 (including installation) and generates enough energy for 200 homes • Smaller turbines (under 100KW) cost around $3000-$5000 per kilowatt of capacity • As more efficient turbines are being developed, the price is steadily decreasing • Wind energy costs about 4 cents/kWh – competitive with natural gas/coal • Using wind energy lowers monthly utility costs by about $8-$15, and about $96-$180 per year
How this source is provided to consumers • This source is provided by wind farms. You would buy your energy from them. • You can also purchase your own wind turbine that would provide energy to a generator that you would also purchase. This is another method to use wind energy and run your house that way as well.
How wind energy gets to your house • When the turbines are spun by the wind, and capture the kinetic energy. This turns a shaft inside the generator that the turbine is linked to. • This powers the generator, which in turn is connected to your house from a wind farm or your own personal generator.
How wind energy effects transportation • Wind energy effects transportation by providing electricity for new up and coming electric cars.
Does it pollute? • The only pollution it gives off is noise pollution. This also depends on how fast the wind is blowing in which it may not produce any noise pollution. • The only other form of pollution that it has is the pollution it takes to put in the wind farm. This is also minimal. • In general this is a very eco friendly energy source.
Is wind energy easy to assimilate into our lives? • Yes it is very easy to assimilate into our lives. • The wind energy comes in from wind farms like any other electrical power plant. • With a personal turbine it is very easy to assimilate just like putting solar panels on a roof.
Can it work well with other forms of energy. • Wind energy can work well with other forms of energy. • A personal turbine would be the equivalent of putting a few solar panels on your roof.
