Recent growth in the renewable energy industry has increased government support for alternative energy. In the United States, hydropower is the largest source of renewable energy and also one of the most efficient. Currently, there are 30,000 megawatts of potential energy capacity through smalland micro-hydro projects throughout the United States. Increased development of micro-hydro could doub...

Land tenure issues such as tenure forms and its allocation and land acquisition procedure are not extensively considered in hydropower development. As a result hydropower projects are not sustainable. The main aim of the study is to find the role of land tenure in hydropower development. Desk study is carried out and is followed by the scientific literature review. The study reveals that the co...

-This paper presents recent work on the control strategy and algorithm for automatic voltage control (AVC) of hydropower station with multiple units and large capacities. Under the conditions that no dynamic voltage problems are considered, a method intended primarily to control steady state voltage of HV bus by economically regulating the reactive power generation of hydropower station is prop...

The current energy crisis in Nepal clearly indicates that the future energy-demand cannot be met by traditional energy-sources. Community-based micro-hydropower operations are considered to be one of the most feasible options for energy development. However, the power plant capacity factor remains very low due to limited commercial and business opportunities. Generation of hydrogen (H2) from th...
