2. RENEWABLE ENERGY SOURCES 3. RENEWABLE ENERGY SOURCES The sun: solar energy. Subsectors: the active solar systems, the passive solar systems and the solar panel conversion. The wind: wind energy. The chutes: hydropower, with restriction on small hydropower of less than 10 MW. Geothermy: geothermal energy: high and low enthalpy. Biomass: thermal or chemical energy with biofuel production, the use of logging residue and the utilization of rural and urban waste. 4. RENEWABLE ENERGY SOURCES Since antiquity, Greek people knew the importance of the renewable energy sources and therefore worshipped them as gods. Specifically they had deified: The wind energy in the face of Aeolus. Aeolus kept the winds in the bag and released them at Zeus command. He had six sons and six daughters, who personified the winds. 5. WiND ENERGY 6. ANCIENT GREEK PEOPLE HAD DEIFIED The solar energy in the face of the sun. The sun, Homer relates him to Titan Hyperion. The sun drove his fiery chariot to Heaven. He had two sisters, his Goddess of the moon, Selene and the Goddess of dawn, Io. 7. SOLAR ENERGY 8. ANCIENT GREEK PEOPLE HAD DEIFIED The water energy in the face of Poseidon. Poseidon was the god of the seas the rivers, of springs and of drinking water. Son of Saturn and Rhea and brother of Zeus lived in Olympus or in his Palace in the depths of the sea. 9. WATER ENERGY 10. GEOTHERMAL ENERGY Geothermal energy is one of the cleanest and most reliable renewable energy sources. It exploits the use of the heat from the interior of the earth. This heat comes out near the surface in the form of steam or hot water through volcanic cracks, circulation of underground water, and also exists in natural reservoirs with very hot water. 11. GEOTHERMAL ENERGY 12. GEOTHERMAL ENERGY IN GREECE Greece has a dynamic of immediate use that exceeds 1000MWth and 25MW for the production of electricity mainly in the islands of Milos and Nisiros. 13. BIOMASS Biomass is a renewable form of energy, well known for many years. Biomass: all material that comes from organic matter such as wood, agricultural residue, livestock waste, industrial discharges and municipal waste, and can be used as fuel for electricity production. Biogas is rich in methane produced from organic waste and can be used to generate heat and electricity, as well as fuel for internal combustion engines. 14. BIOMASS 15. THE KEY FACTORS FOR THE REVIVAL OF INTEREST FOR R.E.S.Starting in the mid 1970s st 1 factor: Energy security The oil crisis of 1973 and 1979-1980 led industrially developed countries to reconsider their absolute dependence on fossil fuel and especially oil. 16. THE KEY FACTORS FOR THE REVIVAL OF INTEREST FOR R.E.S. 2nd factor: The green house effect, major priority of the international community during the past few years. Nevertheless, the energy sector carries the main responsibility for the pollution of the environment because 95% of the atmospheric pollution which leads to planet overheating is due to the production, transformation and the use of conventional fuel. 17. GREENHOUSE EFFECT 18. THE KEY FACTORS FOR THE REVIVAL OF INTEREST FOR R.E.S.3rd factor: The depletion of fossil fuel and the high price of the remaining avantities. It is characteristic, that drillings reach the depth of 12,000 m. in search of new deposits. 4th factor: Nuclear accidents and nuclear wastes drive the public opinion away from nuclear energy. 19. IL CRISIS AND RECESSIONS The golden age of cheap oil and energy efficient markets ended with the oil crises of 1973 and 1979. Result:downturn to economic activity around the world and of course in Europe. 20. Specifically: In 1973, the OPEC countries made a coordinated reduction of oil production, announcing increases in fuel prices. The EU tried to take initiatives to manage crisis but failed to adopt uniform policies.The member states pursued independent policies, which resulted in failure of dealing effectively with the problem. 21. REVIEW OF STRATEGIES FOR ENERGY But the crisis eventually led the Member States and the EU to revise their strategy concerning energy. The EU countries agreed to adopt the "new strategy" (1974) which forsaw: Oil Reduction Utilization of domestic energy production capacities (primarily nuclear). 22. REVIEW OF STRATEGIES FOR ENERGY Reasonable management of energy use. Investments in research and development in the energy sector. Promotion, although to a limited extent, of the use of the R.E.S. 23. MEASURES TO SOLVE THE PROBLEM In 2007,the leaders of the European Union decide the so-called 20-20-20 which means: The nations must reduce their greenhouse gas emissions at the percentage of 20%. On a parallel basis, they have to increase the use of the R.E.S. from 6.5%,of the total produced energy, to 20% until 2020. 24. MEASURES TO SOLVE THE PROBLEM For Greece this means: By 2020, the percentage of the R.E.S. in the national electrical energy production must be at least 29%. Therefore, the target of 20% by the year 2010 should reach 29% by the year 2020. 25.
