3.Although demand-management should always be examined first when additional water is needed, conservation will not always preclude the need for new sourcesofsupply.
5.By using all possible sourcesof clean energy supply through market mechanism, the diversification of energy supply will be promoted, and adequate and stable energy supply security system will be ensured.
8.The analytical results reveal that there are five sourcesof PGEs in coals: magmatic hydrothermal activation, low-temperature hydrothermal fluid, synsedimentary volcanic ash, erogenous supply, and seawater.
10.The Distributed Generation System (DGS), which is composed of various energy sources by parallel connection, is the one of way to dramatically develop renewable energy resource, improve the reliability and expand the capacity of power supply system.
