Globalisation contains a lot of different fields. One part is the process of word wide interaction and linking up between people, companies and nations. The interaction increases especially in the field of politic, economy, culture, environment and communication. This interaction effects individuals in the same way as institutions ore societies. | Globalisation contains a lot of different fields.

A big topic of globalisation is the environment, the sustainable management of limited recourses. I will focus especially on the supply of water. | A big topic of globalisation is the environment, the sustainable management of limited recourses. I will focus especially on the supply of water. | ||

The cultural aspect describes the blending, border-crossing and the spreading of different cultures. There are different chances and risk that can be discussed, therefore advantages and disadvantages of the globalisation for all these different areas concerning every single person as part of the social life and the global living. The different chances and risk concernin one of this fields (eventually social, culutural aspect)in detail will be discussed later in this text. | The cultural aspect describes the blending, border-crossing and the spreading of different cultures.

'''Sustainable Energy – Solar energy | |||
''' | |||
There are a lot of different ways to create energy, but because of the limited capabilities and the growing ozone hole, it is important to use sustainable energy. On one hand the ozone hole gets bigger because of the globalisation, flying by plane, using cars etc., on the other hand the globalisation can help to get new systems of using 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. Just to name some of the consequences. | |||
The other problem are the limited capabilities. Oil is getting low, the oil price already rose from $20 per barrel in 2001 to $70 per barrel in 2006. Either we will run out of oil or it is getting to expensive that just rich people can use it in the future. And because of the ecologically harmful power station, also the electricity will be running out and will be getting expensive. | |||
And especially of the globalisation, the transportation, the high living standard we will use more and more electricity, heat and all the capabilities. That is why it is important to think about other ways of producing energy. | |||
One form of using sustainable energy is the sun. Solar energy is one of the sustainable methods. There a more techniques like wind power or using water for getting energy, but the following text will be written about solar energy; what it is, how it works and what the advantages and disadvantages are. In the beginning it will describe in short form the technical way of this system, afterwards there will be a short term about some other forms of sustainable energy systems. Following the text will move on to the advantages and the disadvantages of using solar energy. And at the end there will be written a conclusion of this way of using sustainable energy. | |||
Already in the 18th century the solar cell was made up. Horace-Bénédict de Saussure was a successful naturalist and 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 refine this technique. It was also the first time when the energy of the sun was used for electricity. | |||
Solar energy means the energy which is produced throw atomic fusion. Lately it is not known that the energy of the sun decreases, it stays constant. Parts of the energy gets reflected and other components of the energy gets absorbed and already changed into heat energy. And the rest gets throw, down to the earth. How much of the sun energy will get to earth depends on the humidity, the cloudiness and the length of the way the sunbeams needs to put back. The energy of the sun is five thousand times higher then the energy the mankind needs. This already is one point why using the energy of the sun. There will still be enough electricity and the limited capabilities of the earth won‘t be used. | |||
