History of Wind Energy, Types of Turbines, and Applications of Wind Energy


“Windmills have fascinated us for centuries and will continue to do so. Like campfires or falling water, they’re mesmerizing; indeed, entrancing.”

Paul Gipe, Wind Power for Home, Farm, & Business


Wind Energy has been Popular for a long time

The pilgrims arrived under the power of wind. Cape Cod was home to the first windmill in America. Wind helped fuel our country’s early economy.


Early “WINDMILL” in Afghanistan (900AD)


Dutch Style Windmills used for 100s of years across the World


Water Pumping Windmills helped settle the American West


Early Electric Wind Turbines helped Electrify Remote Farms in the early 1900’s


Birth of the Modern Wind Turbine

California Wind Turbines 1980’s

Smith-Putnam

1.25 MW Turbine

Vermont, 1940's


Types of Electricity Generating Windmills

  • Small (10 kW)

  • Homes

  • Farms

  • Remote Applications

  • (e.g. water pumping, telecom sites, icemaking)

  • Intermediate

  • (10-250 kW)

  • Village Power

  • Hybrid Systems

  • Distributed Power

  • Large (250 kW - 2+MW)

  • Central Station Wind Farms

  • Distributed Power

What is Wind Power Used For?


Wind Turbine Applications

  • Generating electricity at Remote Sites

  • Producing electricity in parallel with utility

  • Water Pumping


Wind Farms


Offshore Wind


Why do We NeedNew Energy Sources?


Drivers for Wind Power

  • Rising Fuel Price and Uncertainty

  • Declining Wind Costs

  • Federal and State Policies & Incentives

  • Local Economic Development

  • Environmental Stewardship

  • Energy Security

  • Consumer Demand

Concerns about Wind Energy


Some Concerns about Wind(that can be addressed with proper information)

  • Visual / Aesthetic

  • Property Values

  • Noise

  • Birds

  • Safety

  • Are benefits real?


Carnage!


Are the benefits real?

  • Back up Power?

    • Turbines do not require any new back up generation or spinning reserves.

  • Emission reductions?

    • Wind energy is accepted on the grid before any other source when it is available, offsetting the need for more polluting sources. Each MWh of wind is one less MWh of electricity from a fossil fuel plant

  • Economics?

    • Wind provides long-term price stability and is competitive with today’s energy costs. Economic benefit is realized by whoever buys (and sells) the power.


We should not compare wind energy to no wind energy


Need to Change Perceptions…
