    Wind Power Wind Power Presentation Transcript

    • History •Humans have been using wind as a form of power for over 5000 years. •The earliest known form of wind power was used by the Ancient Egyptians.
    • History • The first windmills date back to the early 1100s in the middle east. • Holland is home to some of the oldest windmills in the world. • The earliest windmills were used to grind grain. • First windmill used to generate electricity in the US was installed in 1890.

    • How it Works
    • How it Works
    • Pros and Cons of Wind power Pros Cons •Clean • The wind doesn’t •Renewable always blow •Saves fossil fuels • Limited building •Payoff over-time locations •Least expensive source of electric • Power Storage is power limited • Expensive to install
    • Facts The Wind power capacity in the United States has seen a 400% increase over the last 5 years, with over 24000MW as of 2008 and is expected to grow by another 8,500MW in 2009. Source: http://www.windpowerexpo.org/
    • Facts •Off-shore wind farms can generate 50-70% more power then land based wind farms. •Wind speeds on the open ocean is 30-40% higher then on land. •Wind speeds near shore are 25-20% higher then on land. •The US has the largest offshore wind farm potential of any other country in the world.
    • Facts • The largest offshore wind-farm in the world is located in Great Britain. • Its 54 turbines have a capacity of 194MW, enough to power 130,000 homes. •Steel foundation tubes were hammered 25 meters into the chalk below sea floor.
    • Should I get one?  Who should consider buying a wind turbine? • Persons with property size of one acre or more. • Persons who have at least a 10 mph average wind speed and are paying 10 cents/kWh or more for electricity  How much does a wind system cost? • A small turbine can cost anywhere from $6,000 to $22,000.  How reliable are wind turbines? Will I have to perform much maintenance? • Most small turbines have very few moving parts and do not require any regular maintenance. They are designed for a long life (up to 20 years) and operate completely automatically.  How do wind turbines perform as an investment? • The wind system will usually recoup its investment through utility savings within six to fifteen years.
