Englisch-Korrekturlesen

Ich habe einen Aufsatz geschrieben und ich glaube, es sind ein paar Grammatik-Fehler drin. Wäre sehr nett, wenn ihr den Text korrigieren könntet.


Renewable energy produces up to now only a small part of the global electricity. As renewable all energy sources can be called which regenerate on the new one. They are sustainable available and are nearly inexhaustible. For example, water power, solar energy and the wind power are renewable. As a reaction to the high oil prices of 1973 renewable energy sources came to fashion, however as the oil prices dropped again, the interest decreased.
Only today, 30 years later, solar cells, wind energy and water power stations could create the commercial breakthrough. In the meantime, they have become considerable more efficient and less expensive. Scientifically, economically and politically it is a matter of investing in the long term in it.
The sun is the biggest and most fertile energy source them the people is available. It delivers huge energy amounts in form of radiant energy. During one day the sun contributes the 15000 fold amount on energy of the everyday need of the whole earth population.
The direct use of the solar energy occurs by solar collectors. Solar collectors catch the energy of the sun in form of radiation so that the caught energy is being converted into electric energy directly.
After the unique investment costs for the purchasing and the construction of a solar arrangement, no other costs for other fuels are needed. Although solar arrangements are very ecologically friendly, big amounts of energy are needed for their production.
Solar cells can be installed at the most different places: in the facades or on the roofs of houses, in gigantic plots in the desert, even sewed in clothes as an energy supply of portable electronic equipment.
The biggest challenge consists in reducing the price of solar cells. Thanks to improved production procedures the prices have sunk during the last ten years.
