  1. Module 06 Renewable Energy (RE) Technologies & Impacts (continued) - Use of RE sources in electricity generation, in transport, and in other energy consumption modes Ecological impacts of RE sources, and mitigation measures

  2. RE technology options: • Hydroelectric  • Solar  • Wind  • Geothermal • Marine (Wave and Tidal) • Biofuels (Biomass, Bioethanol and Biodiesel)

  3. Wind Energy Wind power report. 7th ed. London: ABS Energy Research; 2010

  4. Wind Energy Top 05 wind energy users Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  5. Wind Energy Onshore wind farm Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  6. Wind Energy Top 10 onshore wind farms until 2010 Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  7. Wind Energy Top 10 proposed onshore wind farms Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  8. Wind Energy Offshore wind turbine Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  9. Wind Energy Large offshore wind farms Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  10. Wind Energy The nacelle contains the gear box (sometimes), generator, step-up transformer & cooling system

  17. Wind Energy Wind turbine size • In a large modern wind turbine, • - the generator can be 100 times of the size of a similar turbine in 1980, • blade length has increased almost 8 times over the same period. • the rotor diameter ranges from 40 to 90 m, and is rated between 500 kW and 2 MW Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  18. Wind Energy "Aerogenerator X" is a vertical axial machine, that would stretch nearly 275 m from blade tip to tip and would stand nearly 600 ft high above the waves. Each turbine (10 MW capacity) should be able to generate energy equivalent to 2 million barrels of oil in 25-year lifetime.

  19. Wind Energy - Sway (Norway) is planning to build massive floating turbines that would stick straight out of the sea from 100m-deep floating "masts" anchored to the seabed. - An EU-sponsored research project is also investigating 8 –10 MW turbines. - American and Danish companies are planning 9 MW machines. - Full-scale prototypes of all three leading designs are expected to be complete within three years. - These projects have the potential to transform the global energy market forever.

  20. Wind Energy Wind turbine size However manufacture of a large wind turbine could be hampered by factors like special reinforced materials and bespoke lifting vehicles, etc. Leung DYC, Yang Y. Renewable and Sustainable Energy Reviews 16 (2012):1031–39

  21. Wind Energy each Lens measuring 112 meters in diameter, can provide enough energy for an average household.
