Warm Up 1/27/14Voices are at “0”

Evaluate our Learning Target for today.1.Where do we obtain energy? In other words,

what are our sources for energy?2.How do we transform energy? In other

words, what form does it need to be in for us to be able to use it?

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 TurbineVermont, 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

Concerns about Wind Energy

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

Visual / AestheticProperty ValuesNoiseBirdsSafetyAre 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

Alternative Energy Notes 25Jigsaw Reading

1. Each group member take a section of the reading on Energy

2. Read Silently then write facts from your section on a sheet of loose leaf paper. Include Type of Resource (Renewable, Non Renewable, Definitions, Advantages, Disadvantages)

3. When time is called pass your paper to the left. 4. When you get your new paper write the other

person’s information down in your notebook.
