"We do not get the Earth from our parents, we borrow it from our children," this is what the native Americans say. And we should agree with them. The Earth belongs to all generations. We can't use all its resources and pass it on to our children empty and polluted.

However, nobody would agree to stop using oil and gas, to close factories and plants, to give up heating our houses and travelling by air and to go back to primitive tools. We cannot stop technological progress and make it move backwards, can we?

The only correct solution for us is to develop safe technologies and to use renewable energy sources. There are many ways to do this.

Way No.1

The idea to use wind power is not a new one – people built windmills centuries ago. The windmills ground grains, pumped water, and did other jobs. The wind turbines we use today are just a highly upgraded old windmill.

The wind turbine used today is placed on the top of a tall, narrow tower. The wind makes the turbine rotate and the energy of the wind is made into electricity. Like a sunflower turns to face the sun, the turbine turns to face the wind.

It is equipped with a special device to detect the direction of the wind.

Way No. 2

The sun generates a great amount of energy. Some of it reaches our planet and supports life here. Solar energy is actually the cleanest source of energy which will never run out while the Sun shines in the sky.

There are two types of solar technology - active solar and passive solar. Active solar technology involves using special panels with cells.

The cells catch the sun's rays and convert their energy into electricity. Passive solar technologies mean smart engineering solutions and materials. They allow a house to catch and store as much heat energy as needed.
