Solar Energy: Difference between revisions

There are a lot of different ways to create energy, but because of the limited capabilities, it is important to use sustainable energy. Our earth gets more and more abuse, because of the globalisation, flying by plane, using cars etc., on the other hand the globalisation can help us to get new systems for using new ways for getting energy and to get all the materials for it. But the global warming and the accumulation of greenhouse gases in our atmosphere brings extreme weather events and rising sea levels (Curtis, Fred: Climate, Peak Oil, and Globalization: Contradictions of Natural Capital), just to name some of the consequences.   

The other problem are the limited capabilities. Oil is getting low and also it is getting more expensive. The oil price already rose from $20 per barrel in 2001 to $70 per barrel in 2006 (Curtis, Fred: Climate, Peak Oil, and Globalization: Contradictions of Natural Capital). In the future oil will become a product of luxury.

In the future we will either run out of oil or it it will be too expensive for everybody, so that only rich people can use it. Also because of the ecologically harmful power stations electricity will be getting more expensive, and eventually run out (http://www.handelsblatt.com/ (14.11.2009)). So either we will run out of the capabilities, we will have to pay high prices for it or we will harm our world even more.  

Especially because of the globalisation, the transportation and the high standard of living we will use more and more electricity capabilities. That is why it is important to think about other ways to produce energy.

One form of sustainable energy is the sun. Solar energy is one of the sustainable methods. There are also more techniques like wind power or using water for getting energy. The following paragraph will be written about solar energy; what it is, how it works and what the advantages and disadvantages are. In the beginning I briefly will describe in short form the technical way of this system, afterwards there will be a short term, then briefly talk about some other forms of sustainable energy systems. Following I will move on to the advantages and the disadvantages of using solar energy. And at the end there will be written a conclusion this way of using sustainable energy.

In the 18th century the solar cell was invented by Horace-Bénédict de Saussure, a successful naturalist, who came up with the solar cell, similar to the one which is used today. In the 19th century Augustin Mouchot was the first person who used the convex mirror. This was the first step to refining this technique. It was also the first time that the energy of the sun was used for electricity (http://www.ht-handelsagentur.de (14.11.2009)).
