Các công ty công nghiệp thậm chí có thể sản xuất năng lượng gió của họ trong khu vực với gió tốt tài nguyên và chuyển giao quyền lực trên transmissionsystem cho việc sử dụng tại các cơ sở của riêng mình - hoặc bán hàng cho một bên thứ ba. | side walls of the enclosed reservoir. Part of this energy can then be used to pump the remaining water to a high-level reservoir which would operate a conventional hydro-electric power plant. In this way with a capital investment of about US 40 million some 20 MW of electricity can be generated at a cost of only 30 mils per kW h. The possible fish output from the reservoir is estimated at 1 000 tons annum and its value may well exceed that of the electricity. Tidal-wave power-generation has several advantages over conventional resources. Some of the primary advantages are it is a renewable source of energy it is pollutionfree it can produce energy all round the year 24x7x365 hours annum . Interestingly the peak output coincides with peak energy-demand. Moreover water is a free resource. Above all it is highly efficient coal oil efficiency 30 per cent tidal power efficiency 80 per cent . Some of the potential sites of the world so far surveyed are given below6 1. Siberia Russia 2.

Madagascar The current challenge in younger and experimental renewable energysources is that although they have great potential in serving the energyneeds of developed and developing countries alike they first need to prove their full commercial viability. However rapid research and development of these areas and the number of companies working on potentially commercial technologies is a strong sign that these new renewable energysources hold great promise for the future. - 78 - CHAPTER 7 ENERGY POLICY AND PLANNING Situation in .
