  1. Global Warming

  2. Amount of CO2 – emissionsin Germany

  3. The climate change is currently one of the most important concerns in the world. • If we don´t do anything against it, the earth is going to grow warmed • Besides many Mediterranean regions would have 30% less amount of water • For now the priority lies in stopping the climate change, because it most certainly cannot be reversed

  4. Methane: • Australian, British and American scientistsreportthatsince 2007 theconcentrationofmethane in theatmospherehasbeenincreasingagainforalmosttenyears. • As a greenhouse gas, methaneisabout 25 timesaseffectiveas CO2. Itsshareofthe global warmingproblemiscurrently 16 percent.

  5. Climatechange & Environmental protection • The issuesofclimatechangeand environmental protectionareamongthemostimportantofour time. We will explainwhatcontributionyoucanmaketoprotecttheenvironmentby solar energyandhowmuchemissioncanbesavedannually.

  6. Environmental protectionby solar energy • Solar energyis a renewableand clean energy. • More andmore solar and thermal systemsandphotovoltaicsystemsarebeinginstalled, forexampletheincreasefrom 2007 to 2008 was 100 percentin Germany

  7. Solar systemsreducecarbonemissions • A conventionalheatingcauses 603 gramsofclimate-damagingcarbondioxide per kilowatthour. • This gas isresponsibleforamongotherthings • As fortheuseof solar energynosubstancesareburned, thistechnologysaves a large amountofemissionsandprotectstheenvironment. • The amountdepends on the type of solar collectorandthe solar system.

  8. Polluter of climate change

  9. summary • Traditional energy generation in Germany • Co2 emissions of fossil fuels • Share of energy generation • Energy turnaround since 2011 (fukushima) • “Garzweiler 2” (lignite mine) • Co2 emissions per head in Germany

  10. Energy generation in Germany The electricity mix in Germany consists of very different energy sources: coal, nuclear and renewable energy are the most important. In industrialized countries, is a life without electricity hardly conceivable. Electricity is usually generated in power plants, power generation in Germany is now privatized. Electricity is generated by energy forms such as heat or kinetic energy which are converted into electrical energy. Coal has the largest share of electricity generation. http://www.strom-magazin.de/stromerzeugung/

  11. Germany is one of the leading industrial nations!co2 emissions of fossil fuels http://www.gasag.de/SiteCollectionImages/Unternehmen/F%25C3%25BCr%2520Berlin/CO2-Emisssionen-fossiler-energietraeger.jpg

  12. Share of energy generation in 2012 • http://www.forschungs-blog.de/wp-content/uploads/2012/07/120730-Brutto-Stromerzeugung-DE-2011-FhG-AST_V2.jpg

  14.

  15. The energy turnaround since 2011 • A shift away from nuclear energy and towards green energy. This is the principle of German energy policy following the nuclear disaster in Fukushima. • In Germany, energy turnaround is the new buzzword for the nuclear phase-out in politics and in the media. It is to be facilitated by the development of renewable energy. • The term energy turnaround has been around longer and it actually refers to a complete transition to sustainable energy. Not only nuclear, but also the fossil fuels (oil, coal, natural gas) should be replaced by renewable energies (wind energy, hydropower, solar energy, bio-energy and geo-thermal energy). • http://www.lpb-bw.de/energiewende.html

  16. Garzweiler • The lignite mine Garzweiler, is an open pit of RWE Power in the Rhenish lignite mining area in North Rhine-Westphalia and was named after the village in the municipality of GarzweilerJuechen.

  18. Global Warming Consequences of the Climate Change

  19. Extreme weatherconditions

  20. Extreme weather conditions • The winters are warmer • The summers are hotter • The weather conditions are very extreme • Climate Change was not very obvious in Germany thisyear • We had very bad weather, ice and snow in May 2013. This is unusual and definitely does not feel like global warming

  21. Ozone Hole

  22. Ozone Hole • The ozone layer thins out and a hole above the poles originates • Reasons: mainly chlorine atoms • This causes higher solar and ultra violet radiation • This is dangerous for all living beings • From time to time the ozone hole getsbigger

  23. Rising of the sea level

  24. Rising of the sea level • The sea levelisrising 3.2 mm per year on average • Reason: glaciers melt because of warmer temperatures • The heating of the oceans leads to a thermal expansion of the water • The ice is melting → more water in the oceans • Experts forecast a rise of sea levels of two or three metres until 2100

  25. Rising of the sea level in Germany • The sea level is rising in Germany as well • The North Sea and the Baltic Seaarepredictedto flood the north of the country • One third of Germany will beflooded

  26. Floods in Germany • In June there were serious floods in Germany

  27. Floods in Germany • The German government pays 1.5 Billion € and the Federal States pay 3.5 Billion € to remove the damages • There were also floods in 6 other countries • At least 25 people died

  28. Measures against floods • Flooding areas are built to reduce the damage • Several dykes are built Dams Sandbags Mobile barriers Flood protection Retention basins Flooding areas Important measures to ward off floods Less sealed areas
