1 environmental problems and technical solutions
Technical English environmental problems and technical solutions by Sebastian Soik & Huy Pham Duc

2 Structure Environmental problems Development Technical solutions Alternative energy sources Reduction of CO 2 -emissions Recycling

3 Environmental problems
Waste gases and greenhouse gases Produced by: Vehicle exhaust Industry Cfc gases …boost the greenhouse effect ! Vocabulary waste gases Abgase Greenhouse gases Treibhausgase Cfc FCKW Particulate matter - Feinstaub

4 Vocabulary Solar radiation - kosmische Strahlung Thermos Thermoskanne Wavelength el.-m. Wellenlänge Longwave - langwellig

5 Global Warming Vocabulary Global warming - Klimawandel, globale Erderwärmung Prediction - Vorhersage Surface Oberfläche Measurement - Messung Natural habitat - Natürlicher Lebensraum

6 Environmental problems
Garbage Household rubbish Toxic waste Illegal waste disposal Vocabulary Garbage (also waste, rubbish) - Müll waste disposal Müllentsorgung Heavy metals Schwermetalle Toxic Waste Giftmüll Salt mine Salzbergwerk

7 Environmental problems
Modern energy demand Vocabulary Energy demand - Energiebedarf Necessity Notwendigkeit Home appliances - Haushaltsgeräte

8 primary energy consumption from Germany
2. Energy Development Renewable Sources: The wind, Sun, and biomass are three renewable energy sources  primary energy consumption from Germany Art/Years Mineraloil 36,0 % ,6 % Gas 22,7 % ,8 % bituminous coal 12,9 % ,1 % brown coal 11,2 % ,7 % renewable energy 4,6 % ,4 % nuclear energy 12,5 % ,9 % other ,5 % all-up PJ PJ Vocabulary inaugurat - eingeweiht

9 Energy Development -Fossil fuels: There are three main types of fossil fuels: coal, petroleum, and natural gas. .Electricity from fossil fuel power plants produces more CO2-proportion into the atmosphere. . Current governments subsidize renewable energies by an estimated $ billion a year.

10 2. Energy development -CO2 emissions boost the greenhouse effect, the consequence is a massive, global temperature increase reduction of CO2-emission: hybrid engines more renewable energies installation of carbon filters in cars

11 3. Technical Solutions Alternative energy sources – Renewable energy I Wind Vocabulary Renewable energy - Erneuerbare Energien

12 3. Technical Solutions Alternative energy sources – Renewable energy I Wind Operation plan of a windmill / wind turbine Vocabulary windmill - Growian Wind turbine - „Kopf des Growians“ Gearbox - Getriebe Yaw system - Windnachführung Offshore Wind park - Windkraftwerk auf See

13 3. Technical Solutions Alternative energy sources – Renewable energy II Water Hydro electricity power plant Wave energy power plant Vocabulary Hydro electrricity power plant - Wasserkraftwerk Wave energy power plant - Gezeitenkraftwerk

14 3. Technical Solutions Alternative energy sources – Renewable energy II Water Hydro energy power plant operation plan Vocabulary dam - Damm Backwater - Rückstau Carbon neutral - klimaneutral

15 3. Technical Solutions Alternative energy sources – Renewable energy II Water Sea level raiser wave energy power plant operation plan Vocabulary ebb - Ebbe tide - Flut Tides - Gezeiten

16 3. Technical Solutions III Sunlight Solar panels photovoltaics produce carbon neutral & free electric energy Vocabulary Solar panel Solarzelle Junction Verbindung

17 3. Technical Solutions III Sunlight [Video Clip]
