Various renewable energy applications for water operations are described here. Some of them are utility-scale and others are small- scale. Our purpose is to show both the applicability at various scales and, when relevant information is available, the cost/efficiency patterns. Some of the installations are connected to electric power grids that can be used for balancing the production and load and others are isolated and off-grid. 14.1 DEVELOPING COUNTRIES VERSUS HIGH-INCOME COUNTRIES The need to balance production and load can look quite different in high-income and in low-income regions. People in higher-income areas will require power availability round the clock and will usually not accept too many interruptions in power delivery, whereas people getting their first electric power source will probably be more tolerant Downloaded from https://iwaponline.com/ebooks/book-pdf/520710/wio9781780409443.pdf by IWA Publishing user
