All Around the World

Welcome to Kissamos, Crete!

Kissamos is set in beautiful landscapes on the west of Crete 35 km from Chania and has about 15,000 inhabitants. The port of Kissamos links Crete to the nearest island of Kythira and the city's of Kalamata, Gythion and even Piraeus (Athens). As every place on Crete, its history goes far back, and its myths and traditions are still alive.

slide6

Situated in the area of Drapanias, 35 kilometers from Chania on the northwest coast of Crete, Kissamos Windmills Apartments: arouse the fantasy of every Don Quixote, but not to fight with them but to be captured by their friendly warm atmosphere. Perfectly designed apartments with TV, air conditioning, completely equipped kitchen, W.C. and bedroom . You can choose an apartment which has a traditional Cretan floor, a bedroom with an exotic view of Kissamos Gulf, just 100m away that is surrounded from the east by Cape Spatha and the west by Cape Gramvoussa .

The Netherlands

The Multi-Story Windmill

There were once over 10,000 windmills in the Netherlands. Even today there are more than a thousand. And the number increases every year as mills are restored and replica mills built on historic mill sites. Windmills dominate, although there are watermills in the eastern provinces. Rivers in much of the country are however not suitable for watermills. But the flat, low lying land and strong prevailing wind mean that the windmill was widely developed as a source of power.

slide9

There were of course many corn mills. Fortified cites had several mills on their ramparts. But the windmill was also the source of power for land drainage - including land below sea level. Some polders had large numbers of mills used to pump out water, before they were replaced by steam and electrical power.

slide10

The wind was also an important source of power for industry and led to an early industrial revolution - particularly in the area to the north of Amsterdam known as the Zaanstreek. Today it is still possible to see working saw mills, oil mills, paint mills and a paper mill.

In the late 19th century, multi-bladed windmills were used to generate electricity. This one is located at a rural home in Oklahoma.

slide13

Wind power is a renewable energy source because wind is inexhaustible. Our oil, natural gas, and coal will not last forever. For future generations, we need to be using wind resources now.

Wind power is non-polluting, cost effective, and environmentally friendly because it does not deplete our natural resources and it does not threaten our Earth’s global climate by increasing greenhouse gases. Each penny spent on wind power keeps a pound of carbon dioxide out of the air.

slide14

Governor Henry has singled out wind power as one of the state’s brightest economic development opportunities saying, “It’s one way Oklahoma can remain an energy state indefinitely.”

We have WIND!!!

We can clearly power homes and businesses while putting money in landowners’ pockets instead of in Wyoming’s coal mines.

Advantages:

renewable resource

almost free and non-polluting; environmentally friendly

cost effective

Disadvantages:

noise pollution

wildlife impacts

large tracts of land needed

intermittent

storage issues and transmission lines

Can you think of some others?

California's Tehachapi Pass

The Tehachapi Pass is one of the world's largest producer of wind-generated electricity. The more than 5,000 wind turbines in the Tehachapi-Mojave wind resource area of Kern County generate approximately 1.3 Terawatt-hours (1,300,000,000 kWh) per year. This is enough electricity to meet the residential needs of more than 500,000 Southern Californians or nearly one million Europeans.

December 2003 Wind Summary: Weatherford Tower Sensors at 10m and 20m (.pdf document)

This wind rose is for a tall tower near Weatherford, OK and the measurements were made during the month of November 2003 at a height of 20 meters above the ground

Directional distributions of wind energy provided by wind roses are used to help position multiple turbines so that each turbine has a minimal effect on the others.
