Small hydro may be developed by constructing new facilities or through re-development of existing dams whose primary purpose is flood control, or irrigation. Old hydro sites may be re-developed, sometimes salvaging substantial investment in the installation such as penstock pipe and turbines, or just re-using the water rights associated with an ...
Hydropower technology and attitude began to shift in the second half of the 20th century. While countries had largely abandoned their small hydropower systems by the 1930s, the smaller hydropower plants began to make a comeback in the 1970s, boosted by government subsidies and a push for more independent energy producers.

Alternatively, small hydro projects may be built in isolated areas that would be uneconomic to serve from a grid, or in areas where there is no national electrical distribution network. Since small hydro projects usually have minimal reservoirs and civil construction work, they are seen as having a relatively low environmental impact compared ...
Small micro hydro installations may successfully use industrial centrifugal pumps, run in reverse as prime movers; while the efficiency may not be as high as a purpose-built runner, the relatively low cost makes the projects economically feasible. In low-head installations, maintenance and mechanism costs can be relatively high.
It would burn imported coal using a high-temperature technology that emits fewer greenhouse gases. And the company insisted that the people affected by the plant would be identified and protected. Tata’s planning documents noted that some villagers would lose farmland, access to communal grazing land and, in a few cases, their homes.
U.S. data-center power demand could nearly triple in the next three years, and consume as much as 12% of the country's electricity, as the industry undergoes an artificial-intelligence ...
In Switzerland one study suggested that the total installed capacity of small pumped-storage hydropower plants in 2011 could be increased by 3 to 9 times by providing adequate policy instruments. [42] Using a pumped-storage system of cisterns and small generators, pico hydro may also be effective for "closed loop" home energy generation systems ...
Federal regulators are urging people not to use liquid-burning firepits following two deaths and 60 injuries since 2019. 'Extremely dangerous': Feds urge against using select fire pits after 2 ...
