Electricity supply database from the Afghan national authority for electricity supply shows that about only 20% of the population in Afghanistan had access to grid electricity by 2010. The national utility has a total capacity of about 842 MW, out of which about 696 MW was operational. Additionally, many decentralized units (Micro Hydropower (MHP) plants, diesel generators and solar home system...

In our country we have enormous low head potation flows in agricultures and aquacultures with almost fix flow rates that can be used as micro hydro power plants for producing energy. But the main problem is the high capital price per kW. Therefore there is needed to design a simple machine with a good runner for covering the various potential flows. In this paper an axial hydro turbine has desi...

Micro hydropower helps the rural areas to supply power with off grid electrification. This study deals design of micro scheme in Gobecho kebele, Genale Dawa river basin, Ethiopia. The site for construction diversion weir is located upstream Ganga kebele. were implemented based on available hydrological data collected from 1991 2020 discharge at different stations by selecting one, which near ca...

Support for low-carbon energy and opposition to new large dams encourages global development of small hydropower facilities. This support is manifested in national and international energy and development policies designed to incentivize growth in the small hydropower sector while curtailing large dam construction. However, the preference of small to large dams assumes, without justification, t...

Renewable energy is an important topic in China as the country experiences increased wealth and energy demand. Historically, hydropower has been a valuable source of renewable energy production in China, and will continue to be as the Chinese increase hydroelectric facilities by 2020. Using provincial level data from 1980-2010, this paper estimates the relationship between the percentage of hyd...

despite the numerous advantages of large dams, there is still a deep suspicion about the real,long-term benefits and costs of their construction. land use change on a vast scale, displacement of a largepopulation of indigenous people, loss of biodiversity and production of greenhouse gas emissions, as well as environmental, socioeconomic and cultural consequences resulting therefrom, indicate c...
