Run-of-the-river hydroelectricity (ROR)
- ROR is a type of hydroelectric generation plant whereby little or no water storage is provided.
- Substantial flooding of the upper part of the river is not required for run-of-river projects as a large reservoir is not required. As a result, people living at or near the river don't need to be relocated and natural habitats and productive farmlands are not wiped out.
- It does not require the formation of a reservoir thus eliminating the methane and carbon dioxide emissions generally caused by the decomposition of organic matter in the reservoir of a conventional hydro-electric dam.
Science City
- Haryana is about to be set up a Science City in Sonepat.
- The Haryana government has also requested the ministry to consider this as a project of the National Capital Region (NCR) as there is no Science City in NCR and the vicinity.
- Thematic galleries on climate change, biodiversity, cutting-edge science and technology, nanoscience, biotechnology and robotics will be created.
- It will also have a fun science gallery explaining various aspects of science and technology, interactive demonstrations, Laser Show, 3D/4D/5D science-show facilities, virtual reality exhibits, simulator, space theatre etc.
