Wind Energy
The process of using the wind to generate mechanical power or electricity is known as wind power or wind energy. Wind turbines transform the wind's kinetic energy into mechanical energy. This mechanical energy can be employed for specialized operations (such as grain grinding or water pumping) or transformed into electricity by a generator.

Fossil fuel (fossiler Brennstoff) was firstly mentioned by Andreas Libavius, a german physician, in 1597 and later used by Mikhail Lomonosov, a russian polymath (man with high knowledge at different subjects) and scientist, in 1757. The term "fossil fuel" was firstly used by Caspar Neumann, a german chemist, in 1759. Fossil means, that it is obtained by digging into the ground.

Hydrogen (Wasserstoff) was discovered in 1766 by Henry Cavendish, an English scientist, when he made base metals react with acids (Säuren). He called the element "phlogiston". In 1783, A. L. de Lavoisier succeeded in synthesizing the gases hydrogen and oxygen to water. Lavoisier then named hydrogen after two Greek (griechisch) terms: hydro (water) and gennao (I generate) as "hydrogene" – “I generate water”. In 1814, the element symbol "H" was introduced by Berzelius, a Swedish chemist. But how has this element changed over the years?

"Stored deep under us and ready to release"
Expression
The term "geothermal energy" refers to energy stored in the subsurface in the form of heat. At a depth of about 15 meters, the surface temperature remains constant throughout the year. In Switzerland, the temperature below the surface generally increases by around 30°C for every kilometer of depth. The temperature at a depth of 5'000 metres is about 160°C. At depths greater than 1'000 meters, significant amounts of heat above 40°C can be used. This geothermal heat can be obtained using various methods.

Introduction
Copper (Latin cuprum) is a chemical element with the element symbol Cu and atomic number 29. It is a transition metal, in the periodic table it is in the 4th period and the 1st subgroup (according to new counting group 11) or copper group. The Latin name cuprum is derived from (aes) cyprium "ore from the Greek island of Cyprus", where copper was mined in ancient times.
As a relatively soft metal, copper is easy to shape and tough. As an excellent conductor of heat and electricity, it has many uses. It also belongs to the group of coinage metals.
As an important technology or functional metal, copper belongs to the group of semi-precious metals.
Mining
Copper ores are often contain sulphur. Sulphuric acid can be released from mining dumps through weathering processes and washed into the surrounding area by rainwater. The groundwater is because of that in dangerous.
Processing
In the next step , sulphur is going to be seperated from copper. It ist possible that because of that the smelling of SO2 ist very strong und it can cause irritation of the mucous membranes.
Acid rain
Even far-off regions can be affected, as pollutants can be transported by the wind. In this way soil organisms are disturbed and plant communities are damaged.
Example
Copper is often used in cabels and pans. It is a good conductor of electricity.

Florian and I have chosen the theme of transportation. Transport seems to us to be an extremely important factor for our economy.
Almost everything is transported by ship. Over nine billion tonnes of global sea freight per year can be felt not only under the sea but also on the surface: high pollutant measurements of nitrogen dioxide (NO2) in the atmosphere correlate with busy shipping routes. The volume of NO2 from ship exhaust gases is now almost equal to those caused by road traffic. Ozone levels in coastal areas are rising sharply.
Texte 18/2009: Strategie für einen nachhaltigen Güterverkehr (umweltbundesamt.de)
Exemple Germany: "Der zunehmende Güterverkehr hatte in den letzten Jahren wenig damit zu tun, dass aufgrund des Wirtschaftswachstums die Zahl oder das Gewicht der transportierten Güter angewachsen wären. Vielmehr sind andere Ursachen zu suchen. Der Güterverkehrsaufwand5 wuchs – gemessen in Tonnenkilometern (tkm) – wesentlich stärker als das Transportaufkommen. Seit 1960 hat er sich vervierfacht. Das Wachstum beschleunigte sich deutlich in den 1990er Jahren und setzte sich – bei stagnierendem Transportaufkommen – auch nach der Jahrtausendwende fort.
Grund dafür sind zunehmende Transportweiten. So stieg die mittlere Weite eines Lkw-Transportes im gewerblichen Güterverkehr zwischen 1997 und 2005 um 32% von 98 km auf 129 km pro Fahrt. Bei der Bahn stiegen die mittleren Transportweiten im selben Zeitraum um 31% von 230 km auf 301 km.

In order for all the transportation in our world economy to run smoothly, many means of transportation are used, one is airplanes, ships, cars, trucks and so on. They make sure that the product gets from A to B without suffering any damage. Was sehr spannend an diesem ganzen ist, ist der Wasserweg. Es werden 50% des Rohöls per Tanker und ganze 80% aller Güter über Flüsse und Meere transportiert.
