  3. Global warming: fact, no doubt end of summer 2002 August ,1984 Mt. Hood Oregon

  4. THE FACT OF GLOBAL WARMING CAN NOT BE QUESTIONED 1941 2004 Bruce Molnia,Glacier Bay National Park, 2004, U.S. Geological Survey USA

  5. GLOBAL WARMING: FACT, NO DOUBT What is the reason? BECAUSE OF THE PEOLE (LET’S SHAME US)! UNCONTROLLABLE PROCESS?

  6. Global warming, greenhouse effect heat hő visiblelight látható fény CO2 C O2 Energia elnyelés energy dissipation

  7. Drastic increase in carbon dioxide concentration since the industrial revolution

  8. Greenhouse gases: not only carbon dioxide Methane  organic matter decomposition (paddy field, landfill) Nitrous oxide (N2O)  biomass burning, fluidized boiler, catalytic cars, nitrogen fertilizer Chlor-fluor-carbon gases  refrigerators, solvents, blowing

  9. GREENHOUSE EFFECT ALWAYS WAS AND ALWAYS WILL BE; CAUSE: WATER VAPOR http://www.geocraft.com/WVFossils/TableOfCont.html They do not beleve in the role of carbon-dioxide.

  10. Water vapor and greenhouse effect Evaporation increases, Greenhouse Effect intensifies Earth’s average temperature increseas Evaporation increases, amount of cloud increases, irradiation decreases, Earth’ average temperature decreases

  11. PERIODICALLY CHANGING CLIMATE ?GLOBAL WARMING Everything is based on something! Yes, this may cause the warming This is true, but don’t cause such a rapid warming

  12. POSSIBLE CAUSES OF PERIODICALLY CLIMATE CHANGE 1. Periodically change of solar flares (period of time: 11 and 206 years) 2. Change of Earth’s elliptical orbit around the Sun (period of time: 100 000 years) irradiation change - about 0,2%

  13. POSSIBLE CAUSES OF PERIODICALLY CLIMATE CHANGE 3. Angle of Earth’s Axis change (period of time: 41 000 years) 4. Change of day and night equal date (period of time: 22 00 years) irradiation change – about 15% During an equinox, the Earth is not tilted toward or away from the Sun and the length of the day is the same at all points on the Earth's surface.

  14. Air pollutant: heating and cooling effect Particle pollution ↓ global cooling? 25% of atmospheric particle are anthropogenic

  15. There were warmer periods!

  16. CO2 average temperature

  17. Better safe than sorry !

  18. Can we do something against global warming? Developing countries (China, India, etc.): It’s not the biggest problem European Union is committed USA: no commercial interest

  19. Renewable energy against the global warmingNO CARBON DIOXIDE EMISSION Water energy Solar energy Wind energy Geothermal energy Biomass Tidal energy (Lunar energy) Wave energy Let‘s see the possibilities in Hungary ?

  20. Water energy It is a real hydroelectric plant

  21. Hydroelectric plants in Hungary Kisköre 28 MW Tiszalök 11,4 MW Electric power plants in Hungary ~ 9400 MW No level differences on flat area !

  22. Solar energy IT IS SAID, IT IS FREE, LET US USE IT. Low energy density: 1kW/m2 What is the situation in Hungary? Incoming: july 5 kWh/m2day jan. 1,5 kWh/m2day Available: july 2,8 kWh/m2day jan. 1,1 kWh/m2day DOMESTIC HOT WATER SUPPLY (FAMILY HOUSE) 200 dm3 60°C water/day claims: 14 kWh/day Collector surface: ≈ 12 – 15 m2 DOMESTIC HEATING (100 m2 FAMILY HOUSE) Average heat output (6 winter moth): 1,4 kWh/m2. It' average is far from the peak !! claims: 1400 m2 Collector surface: ≈ 140 - 180 m2 Domestic hot water:YES Heating:Not enough

  23. Solar power plant 464 000 m2 collector area 80 MW

  24. Wind energy Well known from ancient time

  25. Wind energy Wind farms on land and off shore 1 MW wind turbine: height : 45 meter, rotor diameter : 55 meter Europe’s wind turbine output: ≈40000 MW Problem: the storage of electric energy. If there is no wind, a conventional fast response power plant capacity must be available.

  26. Geothermal energy

  27. Geothermal energy Hungary’s potential in geothermal energy is quite remarkable Problem: thermal waste The currently used methods for the discharge of utilized thermal water involves: direct discharge into sub-surface water sources (reinjection), discharge into periodical water courses and discharge into receiving waters directly or indirectly (through drainage). Only about 20 are injection wells, although recent legislation prohibits new geothermal systems from being established without injection; only waters used for balneotherapy are allowed to be discharged at the surface.

  28. Energy from biomass Realistic in Hungary ? Different sources Wood Used for hundreds of years. Forest area is not too much in Hungary. forest chips pellet

  29. Energy from biomass energy plants instead of wood Energy willow Energy poplar 1 and 3 years old Szarvas - energy grass 35 km2 1 MW whole area of Hungary 2657 MW
