Wind Energy Basics The Kidwind Project

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 Smith-Putnam 1.25 MW Turbine Vermont, 1940's California Wind Turbines 1980’s

Types of Electricity Generating Windmills Small (  10 kW) Homes Farms Remote Applications (e.g. water pumping, telecom sites, icemaking) Large (250 kW - 2+MW) Central Station Wind Farms Distributed Power Intermediate ( kW) Village Power Hybrid Systems Distributed Power KidWind Project |

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…
