Solar energy : 

Solar energy

Dictionary : 

Dictionary Land = kopno Herb = biljka Provide = omogućiti Oil = nafta Seaweed = alga Seabed = morsko dno Panel = ploča Adopt = prihvatiti Design = dizajan Magnifier glass = (staklo) povećalo

What is solar energy? : 

What is solar energy? Solar energy is energy of the Sun. It’s popular in Germany. When Sun light shines one year to the one square meter of solar cells it provides energy like one hunderd litres of oil.

Base of solar energy : 

Base of solar energy Nature is the best place to learn that we must use solar energy. Lot of animals and herbs need Sun lights. Herb is using Sun lights to get energy for own self. Solar energy is based by it.

Who needs oxygen : 

Who needs oxygen Billions of years ago water green seaweeds began using Sun light like energy resource to produce energy, oxygen and food. That is happening on land too. Animals and people need oxygen to breath.

Why use oil? : 

Why use oil? When herbs fell to the sea bed, natural fuel or oil are absloving out. Lot of factories use this energy. That is worse than solar energy. Smoke is everywhere. Global warning is more dangerous every day.

The best way for environment : 

The best way for environment The best way to use energy of Sun is solar collector. One roof collector in germany gives energy as 3 liters of eating oil per month. Solar cells convert Sun energy to electrical energy.

Using solar panels on Earth : 

Using solar panels on Earth Solar panels are used in the space technology. Satelits and astronauts need lot of energy too. Now they want to use this technology on the Earth. Very good idea.

Utility of solar cells : 

Utility of solar cells Solar cells are adopted in Institut for solar energy systems. Cells convert 34% of Sun energy to electric energy. That is silicon cell. Changed design will show better progress.

Is solar cell simply to make? : 

Is solar cell simply to make? Sun energy passes trought magnifier glass. There are 3 layers of solar cell. Sun light then shines in different spectroum. That means we can use super solar cells for light produced by the Sun.

Large turnable mirror : 

Large turnable mirror Producing energy by solar energy begins by turnable mirror. Face of mirror is always turned to the Sun. We can save a lot of fossile fuel by using this. It is very good to have it at home and save money.

Is there some better way? : 

Is there some better way? Athina Zouni is looking for something more revolutionary. Her vision can help future generations. Answer is in computer reproduction of protein molecule. She knows how it works in process. But she doesn’t know can peolpe copy it.

Questions for you : 

Questions for you What is solar energy? Why don’t use oil? Which country has the most solar collectors? Where began using of solar energy? How much collector saves our money?

Grammar : 

Grammar Herb is using Sun lights. -present continous (use+ing=using) Seaweeds began using Sun light. -past tense (begin, began, begun) That is worse than solar energy. -comparation (bad, worse, the worst) Sun energy passes through magnifier glass. -present simple (pass+es=passes)
