Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy production.
[1] [2] The Sông Đà Reservoir, with a capacity of 9 billion m 3 was formed as the river was dammed. [3] The dam is located in Hòa Bình City of the Hòa Bình Province in the north of Vietnam. It measures 128 m (420 ft) in height, and 970 m (3,182 ft) in length. It is owned by Vietnam Electricity and operated by the Hoa Binh Hydro Power ...
Electricity generation in Laos is produced by one coal-fired power plant and several hydroelectric dams. 53% of power generated in 2016 came from renewable sources.The majority of power produced from the Hongsa plant is exported to Thailand.

Fiber-reinforced plastic tubes were adopted for the penstock and the tailrace instead of steel tubes in order to avoid seawater corrosion and adhesion of barnacles. [1] The pump turbine was partially made of stainless steel resistant to seawater. [1] [5] A 66 kV line connected the power station with the power grid of The Okinawa Electric Power ...
The Shilongba Hydropower Station is the first hydroelectric power plant in China. [31] It was built in Yunnan province in 1912, with a capacity of 240 kW. Due to the subsequent period of political and social instability, little additional progress was made in power infrastructure in the country at that time.
From January 2008 to December 2012, if you bought shares in companies when Donald L. Lucas joined the board, and sold them when he left, you would have a 47.8 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
The energy conversion efficiency of geothermal energies is low, at 10-15%, so that the released thermal energy is much larger than the obtained electrical energy. But thermal energy does not cost anything, so a low energy conversion efficiency does not hurt.
