Wind and Energy and....Stuff
Development of the Technology
People have been harnessing wind power since about 5000 b.c. They often used it to propel their boats around the Nile in Egypt. In the 1950's, the use of wind energy dropped dramatically due to cheap oil and low energy prices. But in the 1970's there was an oil shortage. The government began to build large scale wind turbines. They put 13 turbines into operation. Some states even gave tax incentives for those using alternative energy sources. Although in the late 1980's they took the incentives away and use of wind energy went down. Currently, there are 52,000 wind turbines in 40 states and Puerto Rico. There are 225,000 worldwide. (As of 2012.)
How much does it cost for "Wind Energy"?
There isn't really a price for wind energy but there are prices for things that generate wind energy. Wind Turbines generate wind energy and are roughly $3000 to $8000 per year. The 10 kilowatts machine that is used to power a large home can range from $50000 to $80000 per year. In 2014 the federal governments cost was $1.24 per week. As we got more electricity the price went up so we are not sure how much it is today.
Wind Energy in N.C.
The wind for schools program sponsored by DOE National Renewable Energy.
First, the wind will move the blades on the turbine. Then, the blades will turn a shaft inside the nacelle, or the box at the top of the turbine. The shaft, that's inside the gearbox, will start to increase speed. The generator will then convert rational energy into electrical energy. The transformer converts electricity from 700 v to 33,000 v, which is best for distribution. The National Grid spreads energy around the country.
Are there any concerns to wild life?
Yes. Concerns vary with wild life and enviroments.
the concerns are:
- noise impacts
- sight impacts
- death of birds and bats
- ruining of rural grounds ect...
