1MatlabMATLAB was used to analyze the data, which was from a Bonneville Power Administration (BPA) meteorological site in Oregon.Matlab provides:The ability to perform loopsIntuitive function namesThe ability to read and write Excel filesA program was written toGet the dataCalculate the power using a model taken from http://www.stanford.edu/group/efmh/winds/aj07_jamc.pdf for a GE 1.5 MW turbine2Use of MATLABCalculate the capacity factor and average per-turbine outputCompare this output to the load3

4The wind power and the load5Data AnalysisOur data showed that the wind is highest at nightThe wind speed was lowest around noon.Some of our data proved that the lower the temperature, the better the wind output.

6Using a turbine to model the wind dataWe used a 1.5 MW GE turbine as our modelIt would take 8879 wind turbines to generate as much energy as was consumed by the load. The cost of this would be $12 billion 200 turbines would provide 2.25% of the load at a cost of $260 million The capacity factor is 45.47% very high for a wind farm.The average load is 6.0555 GW over the time period in question.

7Why Wind is the Future Wind shows potential to be the answer. It looks promising as a alternative source of power. The wind is forever freeUnlike fossil fuel power stations, wind turbines do not produce harmful emissions.By dispersing wind farms, a certain percentage of the total energy output can be used for base-load power generation.

8Offshore wind power provides continuous reliable powerWind can be integrated easily with the grid because most of the energy from a wind turbine is already in the form of 60Hz ACAs height increases, wind becomes steadier

9Cons and misconceptions of wind The wind doesnt blow all the time at any given site.The speed of the wind is constantly changing.Some people think its too noisy.

10Do wind turbines kill birds?

11Not in significant numbers!Man-made structure/technologyAssociated bird deaths per year (U.S.)Feral and domestic catsHundreds of millions [source: AWEA]Power lines130 million -- 174 million [source: AWEA]Windows (residential and commercial)100 million -- 1 billion [source: TreeHugger]Pesticides70 million [source: AWEA]Automobiles60 million -- 80 million [source: AWEA]Lighted communication towers40 million -- 50 million [source: AWEA]Wind turbines10,000 -- 40,000 [source: ABC]12Not in my back yard People do not want wind turbines near their houses

BUTMost wind sites are in sparsely populated areasSome of the land is occupied by farmers, but wind turbines do NOT prevent the growth of crops on the landLeasing the right to place wind turbines on the land would be an option.13

14Our ProposalWind would do very little for a city like Knoxville. So we found a place that is such that wind could provide most of its energy 15Santa BarbaraPopulation 90,000 It is located between a mountain and an ocean Both are great places for wind turbines.

16Santa Barbara has a power demand of about 30MW and a peak demand of 50 MW.So what we are proposing is that (10) 6 MW offshore wind turbines be put in place and (20) 2MW wind turbines be put on the mountain The overall cost would be around $150 million 17This plan could be used for small towns all around the USA that are close to the ocean and mountains.Over time the savings in electricity would repay the cost of building wind farms.1819
