tailieunhanh - The ICOLD Committee on “Dams for Hydroelectric Energy”

Thuỷ điện đóng một vai trò quan trọng trong việc đáp ứng với nhu cầu năng lượng, cung cấp khoảng MW (khoảng 20% của tổng số) của năng lượng sạch và năng lượng tái tạo. o Bộ sưu tập, xem xét và thảo luận các dữ liệu tổng hợp về: | Tri An Hydropower Plant in the South Vietnam 400 MW power capacity km3 water storage reservoir The ICOLD Committee on Dams for Hydroelectric Energy - Some topics discussed at the Committee Meeting in Sofia 2008 Mr. Giovanni RUGGERI Chairman of the Committee Hydroelectric power plays an important role in the response to the energy needs supplying about 715000 MW about 20 of the total of clean and renewable energy. o Collection review and discussion of synthetic data about Electricity demand and production Contribution of renewable energies Role of hydro production Evolution in time current situation geographical distribution current trends . .Examples are given in Section Note Data age rapidly emphasis should therefore be given to rather global data and long term trends. o Future Scenarios Long term IEA Int. Energy Agency scenarios to 2050 based on existing and nearcommercial technologies. - IEA 2006 Reference Scenario in which renewables will only constitute of w-orld primary energy demand by 2030 IEA 2006 Alternative Policy Scenario in which renewables share rises to assuming the implementation of policies currently being considered by governments to ensure energy security and reduce CO2 emissions. Some 8200 large dams are currently in operation having hydropower as main or sole purpose. o Collection review and discussion of synthetic data about Hydropower plants sources IHA specialised magazines etc. Dams for hydroelectric purpose source ICOLD World Register of Dams Evolution in time current situation geographical distribution. see examples in Sect. 2 . It s therefore a clear interest to analyse and promote the development of sustainable hydropower dams. o Discussion about the contribution of renewables to energy security the environmental benefits of renewable energy is well known but its contribution to energy security is less widely recognis d security uninterrupted physical avaiablity of energy products on the market at a price which is .
