Презентация к уроку Альтернативные источники энергии

«Это величайшая возможность для нашей страны получить новые энергетические и «зеленые» технологии. Это инвестиции,

которые поступят в Казахстан за

время подготовки к выставке, а так

же дальнейшее использование ее объектов»

WHAT IS WATER ENERGY?

Water energy is energy derived from the power of water, most often its ___1___. Energy sourc

es using water have been around for thousands of years in the form of water clocks and ____2______.

A more recent innovation has been hydroelectricity, or the ___3___ produced by the flow of water over dams. In the twenty-first century scientists are developing water-based applications ranging from tidal power to thermal power.

HYDRO POWER: HARNESSING THE ENERGY OF WATER.

Basics in micro-hydro

Early applications used the power of water for milling, pumping, and driving machinery. Unlike wind and sun, the right hydro source can deliver 24 hours a day, 365 days a year. Allowing to run irrigation pumps and mills and to make clean, ___4__ electricity at reasonable cost.

How it works

Hydro power works through the combination of vertical drop (commonly called “head”) and water flow. The vertical drop creates __5___ and the flow of water in a hydro system provides ongoing source energy. Pressurized __6__ water is very dense and hydro-electric systems ___7__ a very large percentage of the available energy into electricity making it the most effective method of energy conversion.

Task 3

Text 1:

Near our house the powerful and forceful river flows in cool and wet freshness

of fog on the enormous area of a plain. Generally, all surroundings seem great

and majestic.

The landscape is predominantly highlands. Hard bushes covered mountains.

Text 2:

It is the most mysterious and undiscovered place in the world.

Here romance, intrigue and heroism live altogether.

It is a beautiful and peaceful place.

There are glaciers drowned in water, icebergs playing with all blue shades,

charged ice-drifts in the long rows.

Indescribable view and 40 o C degrees below zero (on Celsius) capture our spirit.

Text 3:

Our street is straight and wide.

In summer there are a lot of green plants because on one hand there is a forest line with

a comfortable alley going from the hill. The street is very long and has been covered by

beautiful stony bars. The end of the street goes to the sea.

Wonderful scenery with vast dark blue breadth (ширь) can be seen out of the windows of

high buildings.
