The Global Outlook for Additional Hydropower Useby Ellis L. Armstrong, Ellis L. Armstrong Associates, Salt, Lake City, UT, USA,
Abstract: The present installed capacity of hydropower, worldwide, is nearly 400,000 megawatts which provides approximately 25 percent of the electricity generated. Extensive studies of the 86-Nation World Energy Conference estimate that by the year 2020 the amount of hydropower will increase three to four times. However, the advantages of hydropower greatly increases its relative importance. Hydropower development is affected by technology, economic and environmental impacts, other needs and uses of water, and social factors including legal and political considerations. Major developments require large multidiscipline organizations and objective and extensive planning. Some of the developments now underway are discussed. The present worldwide activity is impressive as is the technology transfer. Training programs underway are important.
